[0013] The present disclosure relates to the field of medical devices, and in particular to an electrode sheet, an electric field therapy system, and a control method. Background Art
[0014] Currently, the main treatments for tumors include surgery, radiotherapy, and chemotherapy, but all have corresponding disadvantages. For example, radiotherapy and chemotherapy can produce side effects and kill normal cells. Using electric fields to treat tumors is also one of the current research and development frontiers. Tumor electric field therapy is a tumor treatment method that uses an electric field generator to generate a low-intensity, medium-high-frequency, alternating electric field to interfere with the mitotic process of tumor cells. Studies have shown that electric field therapy is effective in treating diseases such as glioblastoma, non-small cell lung cancer, and malignant pleural mesothelioma. The electric field applied by this treatment method can affect the aggregation of microtubules, prevent spindle formation, inhibit the mitotic process, and induce apoptosis in cancer cells.
[0015] Existing tumor electric field therapy systems mainly include an electric field generator that generates alternating electric signals for tumor electric field therapy, an adapter electrically connected to the electric field generator, and multiple pairs of electrodes electrically connected to the electric field generator via the adapter. The electric field generator transmits the alternating electric signal for tumor electric field therapy to each electrode via the adapter, and then applies an alternating electric field to the patient's tumor site through the electrode to perform tumor electric field therapy. When the tumor treatment electric field is applied to the patient's body, heat will accumulate at the corresponding position where the electrode is attached to the skin. Therefore, the temperature of the body surface corresponding to the patient's tumor site where the electrode is attached must be monitored in real time. When the body surface temperature is too high, the electric field strength must be adjusted in a timely manner to avoid excessive temperature causing low-temperature burns on the patient's skin.
[0016] Each electrode sheet is provided with multiple electrode units. Conventional electrode sheets have a thermistor element installed on each of the corresponding electrode units, and each thermistor element is connected in parallel with each other. The resistance of the thermistor element changes with temperature, and the change in resistance of the thermistor element corresponds to the temperature change of the body surface to which the electrode unit is applied. Each electrode sheet is provided with eight thermistor elements, and a 10-core cable is provided between each electrode sheet and the adapter. Each electrode sheet transmits the resistance of the eight thermistor elements via the 10-core cable. That is, the 10-core cable includes eight first signal lines that transmit the temperature signal sensed by the thermistor elements to the adapter, as well as one ground line connected to each thermistor element and one first AC line connected to each electrode unit. Regardless of the number of electrode units on the electrode sheet, the number of thermistor elements on the electrode sheet does not exceed eight, and the electrode sheet is connected to the adapter via the 10-core cable. For example, on the electrode sheet with 9 electrode units, 8 thermistor elements are set, so need 8 independent wires to transmit the signals of 8 thermistor elements, at this moment, the thermistor element coverage is 89% (8 / 9=0.89) in the electrode sheet. For another example, if 8 thermistor elements are set at the electrode sheet with 13 electrode units, at this moment, the thermistor element coverage is 62% (8 / 13=0.62) in the electrode sheet. If on the electrode sheet with 20 electrode units, only have 8 thermistor elements to be distributed on 8 of the 20 electrode units, 12 electrode units do not cover thermistor elements, so the temperature of more than half of the electrode units cannot be monitored, easily occur owing to monitoring not being comprehensive and causing the situation of low-temperature burns on patient's skin.
[0017] Therefore, it is indeed necessary to provide an improved electrode sheet, electric field therapy system and control method to comprehensively monitor the temperature of the patient's body surface to which each electrode unit in the electrode sheet is applied.

[0068] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, identical numerals in different drawings represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of electrode sheets, electric field therapy systems, and control methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
[0069] Some first embodiments
[0070] FIG1 illustrates an electric field therapy system according to some embodiments of the present disclosure. As shown in FIG1 , the electric field therapy system includes: at least one pair of electrode sheets 100L1, a first adapter 200L1 connected to the electrode sheets 100L1, and an electric field generator 300L1 connected to the first adapter 200L1. The electric field generator 300L1 provides an alternating electrical signal to the electrode sheets 100L1, causing the electrode sheets 100L1 to generate a therapeutic electric field. The first adapter 200L1 is electrically connected between the electrode sheets 100L1 and the electric field generator 300L1, and is used to transmit the alternating electrical signal generated by the electric field generator 300L1 to the electrode sheets 100L1. In other words, the electric field generator 300L1 is capable of generating an alternating electrical signal, which is transmitted to each electrode sheet 100L1 via the first adapter 200L1, thereby generating a therapeutic electric field for treating tumors between the same pair of electrode sheets 100L1. As shown in FIG1 , in this embodiment, the number of electrode sheets 100L1 is 4. Each electrode sheet 100L1 includes a plurality of electrode elements 112L1 of the same number, and each electrode element 112L1 is electrically connected to the first adapter 200L1. The number of electrode elements 112L1 on each electrode sheet 100L1 is 20. In other embodiments, the electric field therapy system may also have more or fewer electrode sheets 100L1. In other embodiments, each pair of electrode sheets 100L1 has the same number of electrode elements 112L1, and different pairs of electrode sheets 100L1 may have different numbers of electrode elements 112L1.
[0071] The present disclosure also provides an electrode sheet 100L1. FIG2 shows a schematic block diagram of the electrode sheet 100L1 and the first adapter 200L1 in the electric field therapy system according to the first embodiment of the present disclosure. It is worth noting that the arrangement of the electrode elements 112L1 shown in FIG2 is to more clearly illustrate the electrical connection between the electrode sheet and the first adapter. The arrangement of the electrode elements 112L1 shown in FIG2 does not represent the arrangement of the electrode elements 112L1 in the spatial structure. In conjunction with FIG1 and FIG2, the electrode sheet 100L1 includes a flexible circuit board 120L1, a plurality of electrode units 110L1 electrically connected to the flexible circuit board 120L1 at intervals, an adhesive member (not shown) applied to the plurality of electrode units 110L1, and a first cable 130L1 electrically connected to the flexible circuit board 120L1. The flexible circuit board 120L1 is embedded with a first AC line 121L1C, multiple first ground lines 121L1A, and multiple first signal lines 121L1B. The first cable 130L1 has multiple conductors (not shown), each of which is electrically connected to one first AC line 121L1C, multiple first ground lines 121L1A, and multiple first signal lines 121L1B of the flexible circuit board 120L1 in a one-to-one correspondence.
[0072] Each electrode unit 110L1 includes an electrode element 112L1 and a temperature detector 114L1 corresponding to the electrode element 112L1. The electrode element 112L1 and the temperature detector 114L1 are both soldered to the flexible circuit board 120L1. The electrode element 112L1 is configured to apply an alternating electric field to the patient's tumor site. The temperature detector 114L1 is used to detect the temperature of the patient's body surface to which the electrode sheet 100L1 is attached and output a detection signal to the first adapter 200L1. Specifically, the temperature detector 114L1 detects the temperature of the adhesive piece (not shown) of the electrode sheet 100L1 in contact with the patient's body surface, and then indirectly feeds back the temperature signal of the patient's body surface to which the electrode sheet 100L1 is attached through the temperature of the adhesive piece (not shown). Each temperature detector 114L1 has a ground terminal 114L1A and a signal terminal 114L1B. Multiple electrode units 110L1 are divided into multiple groups. Each group of electrode units 110L1 includes at least one electrode unit 110L1.
[0073] The first AC line 121L1C of the flexible circuit board 120L1 is configured to transmit the alternating electrical signal (AC signal) generated by the electric field generator 300L1 to each electrode element 112L1. In this embodiment, the first AC line 121L1C of the flexible circuit board 120L1 is electrically connected to the first cable 130L1, and then electrically connected to the electric field generator 300L1 via the first adapter 200L1. This AC line receives the alternating electrical signal generated by the electric field generator 300L1 and transmits the alternating electrical signal to the electrode elements 112L1. The alternating electrical signal generated by the electric field generator 300L1 is sequentially transmitted through the first adapter 200L1 and the first cable 130L1 to the first AC line 121L1C of the flexible circuit board 120L1.
[0074] At any given time, only one of the multiple first ground lines 121L1A is conductive, while the other three first ground lines 121L1A are disconnected. The multiple first ground lines 121L1A are each used to sequentially short-circuit the temperature detectors 114L1 of a corresponding group of electrode units 110L1 within the multiple groups of electrode units 110L1 to ground. That is, the multiple first ground lines 121L1A short-circuit the multiple temperature detectors 114L1 in each group to ground. The ground terminals 114L1A of the multiple temperature detectors 114L1 in the same group are short-circuited via the same first ground line 121L1A on the flexible printed circuit board 120L1. The ground terminals 114L1A of the multiple temperature detectors 114L1 in different groups and corresponding to each other are connected in parallel via different first ground lines 121L1A on the flexible printed circuit board 120L1.
[0075] Each of the plurality of first signal lines 121L1B is used to short-circuit the temperature detector 114L1 of at most one electrode unit 110L1 in each group of electrode units 110L1 to an external device for receiving a detection signal. Each of the plurality of first signal lines 121L1B is connected to a different temperature detector 114L1 to prevent duplicate signals from being subsequently output by the first signal lines 121L1B. That is, when the number of electrode units 110L1 in a group of electrode units 110L1 is the same as the number of first signal lines 121L1B, each first signal line 121L1B is electrically connected to a temperature detector 114L1 of each of the plurality of electrode units 110L1 in the group. When the number of electrode units 110L1 in a group of electrode units 110L1 is less than the number of first signal lines 121L1B, at least one first signal line 121L1B is not electrically connected to an electrode unit 110L1, and each of the remaining first signal lines 121L1B is electrically connected to a temperature detector 114L1 of a different electrode unit 110L1 in the group of electrode units 110L1. In this embodiment, the external device for receiving the detection signal is the first adapter 200L1. The signal ends 114L1B of the temperature detectors 114L1 in the same group are connected in parallel via different first signal lines 121L1B of the flexible circuit board 120L1, and the signal ends 114L1B of the corresponding temperature detectors 114L1 in different groups are short-circuited via the same first signal line 121L1B of the flexible circuit board 120L1.
[0076] The electrode sheet 100L1 of the present disclosure is located in the same group of multiple temperature detectors 114L1. The ground terminals 114L1A of each of the multiple temperature detectors 114L1 are short-circuited through the same first ground line 121L1A of the flexible circuit board 120L1. The ground terminals 114L1A of each of the multiple temperature detectors 114L1 located in different groups and corresponding to each other are connected in parallel through different first ground lines 121L1A of the flexible circuit board 120L1. The signal terminals 114L1B of each of the multiple temperature detectors 114L1 located in the same group are connected in parallel through different first signal lines 121L1B of the flexible circuit board 120L1. The signal terminals 114L1B of each of the multiple temperature detectors 114L1 located in different groups and corresponding to each other are connected in parallel through the flexible circuit board 120L1. The same first signal line 121L1B of the circuit board 120L1 is short-circuited, and only one first grounding line 121L1A among the multiple first grounding lines 121L1A is turned on at the same time. Through the above-mentioned connection method of the temperature detector 114L1, the first grounding line 121L1A and the first signal line 121L1B, it is possible to achieve time-sharing acquisition of the detection signals of the temperature detectors 114L1 of each corresponding electrode unit 110L1 in different groups by one first signal line 121L1B; through the multiple first signal lines 121L1B, the detection signals of the temperature detectors 114L1 of all the electrode units 110L1 of the electrode sheet 100L1 in different groups can be acquired in a time-sharing manner, thereby making the patient's body surface temperature detection more comprehensive and accurate.
[0077] The first AC line 121L1C, first ground line 121L1A, and first signal line 121L1B embedded within the flexible circuit board 120L1 total ten lines. This allows the first cable 130L1 to be configured as a ten-core cable, minimizing the number of cores in the first cable 130L1 and thus reducing the overall weight of the electrode sheet 100L1. The first ground line 121L1A and first signal line 121L1B embedded within the flexible circuit board 120L1 total nine lines. In this embodiment, the first ground line 121L1A is embedded within the flexible circuit board 120L1 for four lines, and the first signal line 121L1B for five lines.
[0078] In this embodiment, the electrode elements 112L1 in each electrode unit 110L1 are connected in parallel to the first AC line 121L1C. In other embodiments, the electrode elements 112L1 in each electrode unit 110L1 are connected in series to the first AC line 121L1C. In yet another embodiment, the electrode elements 112L1 in each electrode unit 110L1 are connected to the first AC line 121L1C partially in series and partially in parallel.
[0079] The electrode units 110L1 are arranged on the flexible circuit board 120L1 in a roughly two-dimensional array. Referring to FIG2 , the electrode sheet 100L1 in this embodiment has four groups of electrode units 110L1, and each group of electrode units 110L1 has five electrode units 110L1. The electrode sheet 100L1 in this embodiment has 20 electrode units 110L1. The 20 electrode units 110L1 can be arranged in a two-dimensional array. The 20 electrode units 110L1 of the electrode sheet 100L1 can be arranged in four rows and six columns, with the first and fourth rows each having four electrode units 110L1, and the four electrode units 110L1 in each of the first and fourth rows being located in each of the second to fifth columns, and the two middle rows each having six electrode units 110L1, and the six electrode units 110L1 in each of the two middle rows being located in each of the first to sixth columns. Among the 20 electrode units 110L1 arranged in four rows and six columns, five electrode units 110L1 that are close to each other form a group of electrode units 110L1, so that the 20 electrode units 110L1 are grouped into four groups of electrode units 110L1 to facilitate the wiring design of the first AC line 121L1C, the first ground line 121L1A, and the first signal line 121L1B in the flexible circuit board 120L1. The 20 electrode units 110L1 of the electrode sheet 100L1 can also be arranged in four rows and five columns. Each row of the electrode sheet 100L1 includes five electrode units 110L1, forming a group. In other embodiments, the 20 electrode units 110L1 can also be arranged in other ways. Of course, in other embodiments of the present disclosure, the electrode sheet 100L1 can also have other numbers of electrode units 110L1. In short, the implementation of the present disclosure is not limited by the number and arrangement of the electrode units 110L1 of the electrode sheet 100L1.
[0080] Each electrode unit 110L1 includes an electrode element 112L1 and a temperature detector 114L1. In the embodiment shown in FIG2 , the electrode element 112L1 can be a dielectric element, such as a dielectric ceramic sheet, or a polymer dielectric layer provided on the flexible circuit board 120L1. The temperature detector 114L1 can be a thermistor. Of course, in other embodiments of the present disclosure, the temperature detector 114L1 can also be other temperature sensors other than thermistors or other components capable of temperature detection. Each electrode element 112L1 has an opening 1120L1 extending through the middle thereof. The corresponding temperature detector 114L1 is housed in the opening 1120L1 of each electrode element 112L1. Each electrode unit 110L1 can also include a first diode 115L1. The first diode 115L1 is connected in series with the temperature detector 114L1 of the same electrode unit 110L1. It can prevent reverse current flow, thereby preventing the detection signal from other electrode units 110L1 from affecting the temperature detector 114L1.
[0081] 2 includes four first grounding lines 121L1A, each of which is used to ground each electrode unit 110L1 in the same group. The four first grounding lines 121L1A of the electrode sheet 100L1 are first grounding lines 121L1A-1, 121L1A-2, 121L1A-3, and 121L1A-4. Among the four groups of electrode units 110L1 of the electrode sheet 100L1, the first group of electrode units 110L1 includes electrode units 110L1-1 to electrode units 110L1-5, the second group of electrode units 110L1 includes electrode units 110L1-6 to electrode units 110L1-10, the third group of electrode units 110L1 includes electrode units 110L1-11 to electrode units 110L1-15, and the fourth group of electrode units 110L1 includes electrode units 110L1-16 to electrode units 110L1-20. Specifically, the first grounding wire 121L1A-1 is used to ground the first group of electrode units 110L1 (i.e., electrode unit 110L1-1 to electrode unit 110L1-5); the first grounding wire 121L1A-2 is used to ground the second group of electrode units 110L1 (i.e., electrode unit 110L1-6 to electrode unit 110L1-10); the first grounding wire 121L1A-3 is used to ground the third group of electrode units 110L1 (i.e., electrode unit 110L1-11 to electrode unit 110L1-15); and the first grounding wire 121L1A-4 is used to ground the fourth group of electrode units 110L1 (i.e., electrode unit 110L1-16 to electrode unit 110L1-20). It should be noted that these first grounding lines 121L1A can be selectively closed or opened. This can be achieved by connecting each first grounding line 121L1A in series with a first switch 240L1, as described in detail below. The phrase "grounding the electrode unit 110L1" can refer to grounding the temperature detector 114L1 in the electrode unit 110L1, or it can refer to connecting the first diode 115L1 in series with the temperature detector 114L1 of the same electrode unit 110L1 to ground. In short, each first grounding line 121L1A short-circuits the ground terminals 114L1A of the temperature detectors 114L1 of all electrode units 110L1 in each group of electrode units 110L1, connecting them to ground.
[0082] The electrode sheet 100L1 shown in FIG2 also includes five first signal lines 121L1B. One end of each first signal line 121L1B is connected to at most one electrode unit 110L1 in each group of electrode units 110L1, and the other end is used to connect to a first adapter 200L1 for receiving detection signals. In other words, for each group of electrode units 110L1, each first signal line 121L1B can be connected to one of the electrode units 110L1 or not connected to any electrode unit 110L1 in the group of electrode units 110L1. Moreover, each first signal line 121L1B is connected to a different electrode unit 110L1 to avoid subsequent duplication of signals from the first signal line 121L1B. Specifically, the signal end 114L1B of each temperature detector 114L1 of each electrode unit 110L1 in each group of electrode units 110L1 is connected to a different first signal line 121L1B.

[0084] Specifically, each signal end 114L1B of each temperature detector 114L1 in electrode units 110L1-1 to 110L1-5 of the first group of electrode units 110L1 is electrically connected one by one to a corresponding first signal line 121L1B among the five first signal lines 121L1B (first signal line 121L1B-1 to first signal line 121L1B-5). Similarly, each signal end 114L1B of each temperature detector 114L1 in electrode units 110L1-6 to 110L1-10 of the second group of electrode units 110L1 is electrically connected one by one to a corresponding first signal line 121L1B among the five first signal lines 121L1B (first signal line 121L1B-1 to first signal line 121L1B-5). Each signal end 114L1B of each temperature detector 114L1 in electrode units 110L1-11 to 110L1-15 of the third group of electrode units 110L1 is also electrically connected to a corresponding first signal line 121L1B among the five first signal lines 121L1B (first signal line 121L1B-1 to first signal line 121L1B-5).

[0085] In the first group of electrode units 110L1, the signal end 114L1B of the temperature detector 114L1 of the electrode unit 110L1-1 is connected to the first signal line 121L1B-1; the signal end 114L1B of the temperature detector 114L1 of the electrode unit 110L1-2 is connected to the first signal line 121L1B-2; the signal end 114L1B of the temperature detector 114L1 of the electrode unit 110L1-3 is connected to the first signal line 121L1B-3; the signal end 114L1B of the temperature detector 114L1 of the electrode unit 110L1-4 is connected to the first signal line 121L1B-4; and the signal end 114L1B of the temperature detector 114L1 of the electrode unit 110L1-5 is connected to the first signal line 121L1B-5.

[0086] In short, each first signal line 121L1B short-circuits the signal terminals 114L1B of the temperature detectors 114L1 of different groups of corresponding electrode units 110L1 and is used to connect to an external device. The signal terminals 114L1B of each temperature detector 114L1 of each electrode unit 110L1 in the same group are connected to different first signal lines 121L1B and connected to the external device via different first signal lines 121L1B. That is, the signal terminals 114L1B of each temperature detector 114L1 of each electrode unit 110L1 in each group of electrode units 110L1 are connected to their corresponding first signal lines 121L1B and connected to the external device via their corresponding first signal lines 121L1B. The ground terminals 114L1A of each temperature detector 114L1 of each electrode unit 110L1 in the same group are short-circuited to ground via the same first ground line 121L1A. The signal terminals 114L1B of the temperature detectors 114L1 of the different groups of corresponding electrode units 110L1 are all connected to an external device via the same first signal line 121L1B. That is, the signal terminals 114L1B of the temperature detectors 114L1 of the different groups of corresponding electrode units 110L1 are all connected in parallel to the same first signal line 121L1B and are connected to the external device via the first signal line 121L1B. The ground terminals 114L1A of the temperature detectors 114L1 of the different groups of corresponding electrode units 110L1 are each short-circuited to ground via a corresponding first ground line 121L1A. That is, the ground terminals 114L1A of the temperature detectors 114L1 of the different groups of corresponding electrode units 110L1 are each short-circuited to ground via multiple different first ground lines 121L1A. The signal terminals 114L1B of the temperature detectors 114L1 of different and non-corresponding electrode units 110L1 are connected to an external device via different first signal lines 121L1B, and the ground terminals 114L1A of the temperature detectors 114L1 of different and non-corresponding electrode units 110L1 are also short-circuited to ground via different first ground lines 121L1A. That is, the signal terminals 114L1B of the temperature detectors 114L1 of different and non-corresponding electrode units 110L1 are connected to an external device via different first signal lines 121L1B, and the ground terminals 114L1A of the temperature detectors 114L1 of different and non-corresponding electrode units 110L1 are short-circuited to ground via different first ground lines 121L1A.
[0087] First AC line 121L1C, multiple first ground lines 121L1A, and multiple first signal lines 121L1B are all embedded within flexible circuit board 120L1. Flexible circuit board 120L1 is electrically connected to first cable 130L1. First AC line 121L1C, multiple first ground lines 121L1A, and multiple first signal lines 121L1B embedded within flexible circuit board 120L1 are each electrically connected to a corresponding wire core within first cable 130L1.
[0088] During the use of electrode sheet 100L1, detection signals from each temperature detector 114L1 in 20 electrode units 110L1 can be obtained in a time-sharing manner using only five first signal lines 121L1B. Specifically, each of the multiple first grounding lines 121L1A in electrode sheet 100L1 can be individually turned on in sequence. With each first grounding line 121L1A turned on, detection signals from the temperature detector 114L1 in each electrode unit 110L1 in the group of electrode units 110L1 connected to that first grounding line 121L1A can be obtained. Consequently, by sequentially turning on corresponding first grounding lines 121L1A multiple times, detection signals from the temperature detectors 114L1 in all electrode units 110L1 of electrode sheet 100L1 can be obtained. In the prior art, since each temperature detector 114L1 outputs a detection signal simultaneously, 20 independent first signal lines 121L1B are required to realize temperature detection of all electrode elements 112L1, which will make the wiring of the flexible circuit board 120L1 more difficult, the processing difficult, and the cost increased; and it will also require the corresponding first cable 130L1 to include 22 wire cores (including an additional first ground wire 121L1A and a first AC wire 121L1C), which will greatly increase the overall weight of the electrode sheet 100L1 and increase the manufacturing cost of the first cable 130L1. As can be seen from the embodiment of Figure 2, the first cable 130L1 of the electrode sheet 100L1 of the present invention only includes 10 cores (not shown), namely 4 cores (not shown) electrically connected to the first ground line 121L1A, 5 cores (not shown) electrically connected to the first signal line 121L1B, and 1 core (not shown) electrically connected to the first AC line 121L1C, thereby effectively controlling the overall weight of the electrode sheet 100L1, avoiding the increase in the number of cores (not shown) of the first cable 130L1 affecting the adhesion effect between the electrode sheet 100L1 and the patient's tumor site, and reducing processing costs; in addition, the flexible circuit board Only one first AC line 121L1C, five first signal lines 121L1B and four first ground lines 121L1A are arranged on 120L1 to obtain the detection signals of the temperature detectors 114L1 of each of the 20 electrode units 110L1, and can comprehensively monitor the temperature of all electrode units 110L1 of the electrode sheet 100L1, and then control the alternating electric signal applied to the electrode sheet 100L1 through the temperature signal of each electrode unit 110L1, so as to avoid the electrode units 110L1 of the electrode sheet 100L1 from being too high and causing low-temperature burns on the skin surface of the patient to which it is applied. At the same time, it simplifies the wiring design of the flexible circuit board 120L1 and reduces the manufacturing cost.
[0089] In this embodiment, each electrode sheet 100L1 may further include a first connector 180L1. Each first connector 180L1 is configured to connect a corresponding electrode sheet 100L1 to a first adapter 200L1. In this embodiment, as shown in FIG1 , the first connector 180L1 is a first plug and is disposed at an end of the first cable 130L1 of the corresponding electrode sheet 100L1 that is distal from the flexible circuit board 120L1. The first adapter 200L1 is provided with a first socket 260L1 corresponding to each of the multiple first connectors 180L1. First connector 180L1 has ten interfaces (1-10) corresponding to the wire cores (not shown) of first cable 130L1. First connector 180L1 is plugged into corresponding first receptacle 260L1 of first adapter 200L1 to electrically connect four first ground wires 121L1A, five first signal wires 121L1B, and one first AC wire 121L1C on flexible circuit board 120L1 to first adapter 200L1. First connector 180L1 is configured as a plug to facilitate quick installation and removal of electrode sheet 100L1 and first adapter 200L1. If one electrode sheet 100L1 fails, it can be replaced with another electrode sheet 100L1.
[0090] The number of first ground lines 121L1A embedded in the flexible circuit board 120L1 of the present disclosure is related to the number of groups into which the plurality of electrode units 110L1 arranged on the flexible circuit board 120L1 are divided. That is, the number of first ground lines 121L1A is the same as the number of groups of electrode units 110L1 in the electrode sheet 100L1. The number of first signal lines 121L1B embedded in the flexible circuit board 120L1 is related to the number of electrode units 110L1 in each group of the electrode sheet 100L1. Specifically, the number of first signal lines 121L1B embedded in the flexible circuit board 120L1 is related to the group of electrode units 110L1 with the most electrode units 110L1 among the groups of electrode units 110L1. Specifically, the number of first signal lines 121L1B embedded in the flexible circuit board 120L1 is the same as the total number of electrode units 110L1 in the group with the most electrode units 110L1. The total number of the first ground lines 121L1A and the first signal lines 121L1B is less than the number of the temperature detectors 114L1 .
[0091] The present disclosure also provides an electric field therapy system. The electric field therapy system of the present disclosure will be described in detail below with reference to Figures 1 to 3. The electric field therapy system of the present disclosure includes at least one pair of the above-mentioned electrode sheets 100L1, a first adapter 200L1 electrically connected to the electrode sheets 100L1, and an electric field generator 300L1 electrically connected to the first adapter 200L1. The first adapter 200L1 is connected between the electrode sheet 100L1 and the electric field generator 300L1. The electric field generator 300L1 provides an alternating electric signal to each electrode element 112L1 in the multiple groups of electrode units 110L1 of the electrode sheet 100L1 via the first adapter 200L1 and the first AC line 121L1C of the electrode sheet 100L1. The first adapter 200L1 transmits the alternating electric signal generated by the electric field generator 300L1 to the first AC line 121L1C of the electrode sheet 100L1 and is also configured to receive detection signals output by the multiple first signal lines 121L1B of the electrode sheet 100L1.
[0092] 2 , the first adapter 200L1 includes multiple sets of first switches 240L1, a first controller 210L1, multiple sets of first analog-to-digital converters 220L1, and a first communication transceiver 250L1. The first adapter 200L1 includes multiple circuit lines (unnumbered). These circuit lines (unnumbered) are electrically connected to multiple first ground lines 121L1A, multiple first signal lines 121L1B, and one first AC line 121L1C within a corresponding flexible printed circuit board 120L1 via the first cables 130L1 of the corresponding electrode sheet 100L1.
[0093] Each group of first switches 240L1 is provided with a plurality of first switches 240L1, each of which is connected to the first adapter 200L1 and is electrically connected to a circuit line (not numbered) corresponding to each of the plurality of first ground lines 121L1A of the corresponding electrode sheet 100L1, and is configured to control the conduction or disconnection of the plurality of first ground lines 121L1A. The plurality of circuit lines (not numbered) electrically connected to the plurality of first ground lines 121L1A of the electrode sheet 100L1 are grounded at one end close to the first switch 240L1. As shown in FIG2 , the plurality of first switches 240L1 are respectively first switches 240L1-1, 240L1-2, 240L1-3 and 240L1-4. The plurality of first switches 240L1 in the same group all control the closing and disconnection of the plurality of first ground lines 121L1A of the flexible circuit board 120L1 of the same electrode sheet 100L1. Specifically, the plurality of first switches 240L1 in the same group respectively control the closing or disconnection of the first grounding line 121L1A electrically connected thereto in the same electrode sheet 100L1. In this embodiment, the first switch 240L1-1 is used to control the closing or disconnection of the first grounding line 121L1A-1 of the corresponding electrode sheet 100L1, thereby controlling the power on and off of each temperature detector 114L1 of the first group of electrode units 110L1 (i.e., electrode units 110L1-1 to 110L1-5) of the electrode sheet 100L1; the first switch 240L1-2 is used to control the closing or disconnection of the first grounding line 121L1A-2 of the electrode sheet 100L1, thereby controlling the power on and off of each temperature detector 114L1 of the second group of electrode units 110L1 (i.e., electrode units 110L1-6 to 110L1-10) of the electrode sheet 100L1. Power off; the first switch 240L1-3 is used to control the closing or disconnection of the first grounding line 121L1A-3 of the electrode sheet 100L1, thereby controlling the power on and off of each temperature detector 114L1 of the third group of electrode units 110L1 (i.e., electrode unit 110L1-11 to electrode unit 110L1-15) of the electrode sheet 100L1; the first switch 240L1-4 is used to control the closing or disconnection of the first grounding line 121L1A-4 of the electrode sheet 100L1, thereby controlling the power on and off of each temperature detector 114L1 of the fourth group of electrode units 110L1 (i.e., electrode unit 110L1-16 to electrode unit 110L1-10) of the electrode sheet 100L1. The above-mentioned multiple first switches 240L1 can be mechanical first switches, such as relays. The multiple first switches 240L1 can also be electronic switches, and each first switch 240L1 can be opened and closed by an additional controller.
[0094] In this embodiment, the first switches 240L1 are all electronic switches. The first controller 210L1 is connected to multiple groups of first switches 240L1 and is used to cyclically control the on / off states of multiple first switches 240L1 in each group of first switches 240L1, and to sequentially and individually connect each of the multiple first grounding wires 121L1A of the corresponding electrode sheet 100L1 to continuously monitor the temperature signals detected by all temperature detectors 114L1 on the electrode sheet 100L1, thereby indirectly obtaining the temperature of the patient's body surface to which each electrode unit 110L1 of the electrode sheet 100L1 is attached.
[0095] Each group of first analog-to-digital converters 220L1 is electrically connected to the multiple first signal lines 121L1B of the electrode sheet 100L1 through the multiple circuit lines (unnumbered) within the first adapter 200L1, the first cable 130L1 of the corresponding electrode sheet 100L1, and is configured to receive the detection signals transmitted by the multiple first signal lines 121L1B of the corresponding electrode sheet 100L1, and convert the detection signals from analog signals to digital signals. Each group of first analog-to-digital converters 220L1 includes multiple detection channels A, B, C, D, and E, each detection channel being used to connect to a corresponding first signal line 121L1B in the multiple first signal lines 121L1B. As shown in Figure 2, each group of first analog-to-digital converters 220L1 includes a total of 5 detection channels, namely, the first detection channel A, the second detection channel B, the third detection channel C, the fourth detection channel D, and the fifth detection channel E. The first detection channel A is connected to the first signal line 121L1B-1, the second detection channel B is connected to the first signal line 121L1B-2, the third detection channel C is connected to the first signal line 121L1B-3, the fourth detection channel D is connected to the first signal line 121L1B-4, and the fifth detection channel E is connected to the first signal line 121L1B-5. Each detection channel is used to receive the detection signal of the temperature detector 114L1 of the electrode unit 110L1 to which the corresponding first signal line 121L1B is connected. In addition, each detection channel is connected to the power supply voltage source (VCC) via the first voltage divider resistor 230L1 (high-precision resistor) in the first adapter 200L1 to provide a detection voltage to the detection channel. The power supply voltage source (VCC) is a DC power supply.
[0096] The first communication transceiver 250L1 is configured to obtain multiple groups of digital signals output by the first analog-to-digital converter 220L1 and send the digital signals to the electric field generator 300L1. The electric field generator 300L1 is also configured to adjust the voltage of the alternating electric signal applied to the electrode elements 112L1 in the multiple groups of electrode units 110L1 of the electrode sheet 100L1 according to the received digital signal. For example, when any digital signal among the multiple digital signals received exceeds a preset threshold, it means that the temperature of at least one electrode element 112L1 in the electrode sheet 100L1 exceeds a preset threshold temperature (for example, 41°C, 42°C, etc.). At this time, the voltage of the alternating electric signal output by the electric field generator 300L1 can be appropriately reduced to avoid the electrode sheet 100L1 causing low-temperature burns to the patient's skin. The above-mentioned preset threshold temperature and preset threshold value can be determined based on relevant experimental data, and the range can be 37-42°C. The first communication transceiver 250L1 is controlled by the first controller 210L1 and serially transmits a plurality of sets of digital signals converted by the first analog-to-digital converter 220L1 .
[0097] The working principle of the electric field therapy system of the present disclosure will be described in detail below with reference to FIG. 2 .
[0098] Each detection channel of each group of first analog-to-digital converters 220L1 simultaneously collects the detection signal of only one corresponding temperature detector 114L1 in the same group of electrode units 110L1. This detection signal can be a voltage value. Only one of the four first switches 240L1 can be turned on at a time; the other three are turned off. With this configuration, each group of first analog-to-digital converters 220L1 can only collect the voltage values of all temperature detectors 114L1 in the group of electrode units 110L1 that have a first ground line 121L1A shorted to the corresponding first switch 240L1 that is turned on. Specifically, when the first switch 240L1-1 is closed, the other three first switches 240L1-2, 240L1-3, and 240L1-4 are all disconnected, the temperature detectors 114L1 of the electrode units 110L1-1 to 110L1-5 are powered on, and the temperature detectors 114L1 of the electrode units 110L1-6 to 110L1-20 are powered off. The temperature detectors 114L1 of the electrode units 110L1-1, 110L1-6, 110L1-11, and 110L1-16 are short-circuited on the first detection channel A of the first analog-to-digital converter 220L1. The ground terminals 114L1A of the temperature detectors 114L1 of electrode units 110L1-6, 110L1-11, and 110L1-16 are all disconnected, and each electrode unit 110L1 is provided with a first diode 115L1 connected in series with its temperature detector 114L1, which does not affect the resistance of the temperature detector 114L1 of electrode unit 110L1-1. Therefore, only the temperature detector 114L1 of electrode unit 110L1-1 is effectively operating on the first detection channel A of the first analog-to-digital converter 220L1, and the detected signal (voltage value) is the voltage value of the temperature detector 114L1 of electrode unit 110L1-1. Similarly, the voltage value collected on the second detection channel B of the first analog-to-digital converter 220L1 is the voltage value of the temperature detector 114L1 of electrode unit 110L1-2. The voltage value collected by the third detection channel C of the first analog-to-digital converter 220L1 is the voltage value of the temperature detector 114L1 of the electrode unit 110L1-3. The voltage value collected by the fourth detection channel D of the first analog-to-digital converter 220L1 is the voltage value of the temperature detector 114L1 of the electrode unit 110L1-4. The voltage value collected by the fifth detection channel E of the first analog-to-digital converter 220L1 is the voltage value of the temperature detector 114L1 of the electrode unit 110L1-5.
[0099] The first controller 210L1 and the multiple groups of first analog-to-digital converters 220L1 can automatically perform operations through pre-programmed program codes. For example, the first controller 210L1 first closes the first switch 240L1-1 among the multiple groups of first switches 240L1, and opens the remaining first switches 240L1-2 to 240L1-4. During this period, the multiple groups of first analog-to-digital converters 220L1 obtain the detection values of each detection channel and store them in a separately provided memory. Then, after a preset time interval, the first controller 210L1 closes the first switch 240L1-2 among the multiple groups of first switches 240L1 again, and opens the first switch 240L1-1, the first switch 240L1-3 and the first switch 240L1-4. During this period, the multiple groups of first analog-to-digital converters 220L1 obtain the detection values of each detection channel. By turning on each of the multiple groups of first switches 240L1 in sequence, the detection values of all temperature detectors 114L1 on the electrode sheet 100L1 can be obtained, and further the detection values of all temperature detectors 114L1 on at least one pair of electrode sheets 100L1 can be obtained through this operation.

The second connector 280L1 is configured to connect the first adapter 200L1 to the electric field generator 300L1. Figure 3 is a schematic block diagram of the first adapter 200L1 and the second connector 280L1 in the electric field therapy system of the present disclosure embodiment. As shown in Figure 3, the second connector 280L1 may include 8 input ports (1-8), wherein the 1st to 4th input ports are respectively used to connect to the corresponding first connector 180L1, and are used to further transmit the alternating electric signal generated by the electric field generator 300L1 to the first AC line 121L1C of the corresponding electrode sheet 100L1 through the corresponding first connector 180L1, so that the electrode element 112L1 of each electrode unit 110L1 on the electrode sheet 100L1 is connected to the alternating electric signal and applied to the patient's tumor site and form an alternating electric field for treating the tumor with the opposite electrode sheet 100L1. The fifth input port is used to ground the first adapter 200L1, the sixth input port is connected to the first controller 210L1 and is used to provide a power supply voltage (VCC) to the first controller 210L1, and the seventh and eighth input ports are connected to the transmitter and receiver of the first communication transceiver 250L1 via lines TX and RX, respectively.

Second cable 270L1 may include multiple wires, each corresponding to a plurality of input ports of second connector 280L1. Second connector 280L1 may be similar to first connector 180L1 and configured as a plug to facilitate connection and disconnection with electric field generator 300L1.
[0102] FIG4 shows a schematic block diagram of an electrode sheet 100L2 and a first adapter 200L2 in an electric field therapy system according to a second embodiment of the present disclosure. Unlike the electric field therapy system shown in FIG2 , the electrode sheet 100L2 in this embodiment includes only 13 electrode units 110L2. As shown in FIG4 , these 13 electrode units 110L2 are divided into three groups, with the first two groups each containing five electrode units 110L2, and the third group containing only three electrode units 110L2. Therefore, of the four first ground lines 121L2A of the electrode sheet 100L2 shown in FIG4 , only three first ground lines 121L2A are effectively energized. Furthermore, the electrode sheet 100L2 includes five first signal lines 121L2B, each of which is connected to a temperature detector 114L2 of at most one electrode unit 110L2 in each group of electrode units 110L2. Specifically, the first signal lines 121L2B-1, 121L2B-2 and 121L2B-3 are respectively connected to the temperature detectors 114L2 of a corresponding electrode unit 110L2 in each of the three groups of electrode units 110L2, while the first signal lines 121L2B-4 and 121L2B-5 are only connected to the temperature detectors 114L2 of a corresponding electrode unit 110L2 in each of the first two groups of electrode units 110L2, and the first signal lines 121L2B-4 and 121L2B-5 are not connected to the electrode unit 110L2 in the third group. That is, first signal lines 121L2B-1, 121L2B-2, and 121L2B-3 are each connected in parallel to the signal terminals 114L2B of the temperature detectors 114L2 of the three electrode units 110L2, while first signal lines 121L2B-4 and 121L2B-5 are only connected in parallel to the signal terminals 114L2B of the temperature detectors 114L2 of the two electrode units 110L2. The control method of the electric field therapy system shown in FIG4 is similar to the control method of the electric field therapy system shown in FIG2 and will not be repeated here. The only difference is that the electric field therapy system shown in FIG4 only requires closing three first switches 240L2 (first switches 240L2-1, 240L2-2, and 240L2-3) in sequence, and while first switch 240L2-3 is closed, only the first three detection channels (A, B, and C) of the first analog-to-digital converter 220L1 can obtain detection signals.
[0103] Figure 5 shows a schematic block diagram of an electrode sheet 100L3 and a first adapter 200L3 in an electric field therapy system according to a third embodiment of the present disclosure. Compared to the electric field therapy system of the first embodiment, the electrode sheet 100L3 of this embodiment has an electrode unit 110L3 with the same structure as the electrode sheet of the first embodiment. Each electrode unit 110L3 includes an electrode element 112L3, a temperature detector 114L3, and a first diode 115L3 connected in series with the temperature detector 114L3. Each electrode element 112L3 has an opening 1120L3 extending through the middle thereof, and the corresponding temperature detector 114L3 and first diode 115L3 are housed in the opening 1120L3 of each electrode element 112L3.

This embodiment also has the same electric field generator (not shown) as the first embodiment. Unlike the electric field therapy system of the first embodiment, the electrode sheet 100L3 of this embodiment includes only 13 electrode units 110L3. As shown in FIG5 , these 13 electrode units 110L3 form three groups of electrode units 110L3, with the first two groups each containing five electrode units 110L3, and the third group containing only three electrode units 110L3. In this embodiment, the flexible circuit board 120L3 of the electrode sheet 100L3 is embedded with three first ground lines 121L3A, five first signal lines 121L3B, and one first AC line 121L3C. Each first signal line 121L3B is connected to the temperature detector 114L3 of at most one electrode unit 110L3 in each group of electrode units 110L3. Specifically, first signal lines 121L3B-1, 121L3B-2, and 121L3B-3 are each connected to the temperature detector 114L3 of a corresponding electrode unit 110L3 in each of the three groups of electrode units 110L3. First signal lines 121L3B-4 and 121L3B-5 are only connected to the temperature detector 114L3 of a corresponding electrode unit 110L3 in each of the first two groups of electrode units 110L3. First signal lines 121L3B-4 and 121L3B-5 are not connected to the electrode unit 110L3 in the third group. The three first ground lines 121L3A are each connected to each electrode unit 110L3 in a corresponding group of electrode units 110L3. Similar to the first embodiment, the ground terminals 114L3A of the plurality of temperature detectors 114L3 located in the same group of electrode units 110L3 are short-circuited via the same first ground line 121L3A of the flexible circuit board 120L3, while the ground terminals 114L3A of the plurality of temperature detectors 114L3 located in different groups and corresponding to each other are connected in parallel via different first ground lines 121L3A of the flexible circuit board 120L3.The signal ends 114L3B of the plurality of temperature detectors 114L3 located in the same group of electrode units 110L3 are connected in parallel via different first signal lines 121L3B of the flexible circuit board 120L3, and the signal ends 114L3B of the plurality of corresponding temperature detectors 114L3 located in different groups are short-circuited via the same first signal line 121L3B of the flexible circuit board 120L3.
[0104] In this embodiment, the first cable (not shown) has nine conductors. The nine conductors of the first cable (not shown) are connected one-to-one with three first ground wires 121L3A, five first signal wires 121L3B, and one first AC wire 121L3C embedded in the flexible circuit board 120L3.
[0105] In this embodiment, each set of first switches 240L3 within the first adapter 200L3 comprises three first switches 240L3-1, 240L3-2, and 240L3-3. When either first switch 240L3-1 or first switch 240L3-2 is closed, all detection channels (A, B, C, D, and E) of the first analog-to-digital converter 220L3 can obtain detection signals. When first switch 240L3-3 is closed, only the first three detection channels (A, B, and C) of the first analog-to-digital converter 220L3 can obtain detection signals.
[0106] FIG6 shows a schematic block diagram of an electrode sheet 100L4 and a first adapter 200L4 in an electric field therapy system according to a fourth embodiment of the present disclosure. The electric field therapy system of the fourth embodiment is substantially the same as that of the third embodiment, except that the 13 electrode units 110L4 of the electrode sheet 100L4 of this embodiment are grouped differently, with the first two groups each containing four electrode units 110L4, and the third group containing five electrode units 110L4. In this embodiment, the flexible circuit board 120L4 of the electrode sheet 100L4, which is composed of a flexible circuit board, is also embedded with three first ground lines 121L4A, five first signal lines 121L4B, and one first AC line 121L4C. Among them, the first signal lines 121L4B-1, 121L4B-2, 121L4B-3 and 121L4B-4 are all connected to the temperature detector 114L4 of a corresponding electrode unit 110L4 in each of the three groups of electrode units 110L4, while the first signal line 121L4B-5 is only connected to the temperature detector 114L4 of a corresponding electrode unit 110L4 in the third group of electrode units 110L4, and the first signal line 121L4B-5 is not connected to the electrode units 110L4 of the first two groups.
[0107] Similar to the third embodiment, in this embodiment, the ground terminals 114L4A of the plurality of temperature detectors 114L4 within the same group of electrode units 110L4 are short-circuited via the same first ground line 121L4A on the flexible circuit board 120L4. The ground terminals 114L4A of the plurality of temperature detectors 114L4 within different groups and corresponding to each other are connected in parallel via different first ground lines 121L4A on the flexible circuit board 120L4. The signal terminals 114L4B of the plurality of temperature detectors 114L4 within the same group of electrode units 110L4 are connected in parallel via different first signal lines 121L4B on the flexible circuit board 120L4. The signal terminals 114L4B of the plurality of temperature detectors 114L4 within the same group of electrode units 110L4 are short-circuited via the same first signal line 121L4B on the flexible circuit board 120L4.
[0108] Figure 7 shows a schematic block diagram of an electrode sheet 100L5 and a first adapter 200L5 in an electric field therapy system according to a fifth embodiment of the present disclosure. The electrode sheet 100L5 of the electric field therapy system of the fifth embodiment has the same number of electrode units 110L5 as the corresponding electrode sheets of the electric field therapy systems of the third and fourth embodiments. The difference lies in the different grouping of the 13 electrode units 110L5 of the electrode sheet 100L5 of this embodiment. In this embodiment, the electrode units 110L5 are divided into four groups, with the first three groups each containing three electrode units 110L5, and the fourth group containing four electrode units 110L5. In this embodiment, the flexible circuit board 120L5 of the electrode sheet 100L5, which is composed of a flexible circuit board, is embedded with four first ground lines 121L5A, four first signal lines 121L5B, and one first AC line 121L5C. First signal lines 121L5B-1, 121L5B-2, and 121L5B-3 are all connected to the temperature detector 114L5 of a corresponding electrode unit 110L5 in each of the four groups of electrode units 110L5, while first signal line 121L5B-4 is only connected to the temperature detector 114L5 of a corresponding electrode unit 110L5 in the fourth group of electrode units 110L5. Similar to the previous embodiment, in this embodiment, the ground terminals 114L5A of the multiple temperature detectors 114L5 in the same group of electrode units 110L5 are all short-circuited via the same first ground terminal 121L5A on the flexible printed circuit board 120L5, while the ground terminals 114L5A of the corresponding multiple temperature detectors 114L5 in different groups are connected in parallel via different first ground terminals 121L5A on the flexible printed circuit board 120L5. The signal ends 114L5B of the multiple temperature detectors 114L5 located in the same group of electrode units 110L5 are connected in parallel through different first signal lines 121L5B of the flexible circuit board 120L5, and the signal ends 114L5B of the multiple temperature detectors 114L5 located in different groups and corresponding to each other are short-circuited through the same first signal line 121L5B of the flexible circuit board 120L5.
[0109] This embodiment includes a first cable (not shown) having the same number of conductors as the third and fourth embodiments. The nine conductors of the first cable (not shown) are connected in a one-to-one correspondence with four first ground lines 121L5A, four first signal lines 121L5B, and one first AC line 121L5C embedded in the flexible circuit board 120L5.
[0110] The first adapter 200L5 of this embodiment has the same first controller 210L5 and first communication transceiver 250L5 as the first adapters of the third and fourth embodiments. The first switch 240L5 of the first adapter 200L5 of this embodiment differs from the first switches of the third and fourth embodiments. In this embodiment, the first adapter 200L5 has four first switches 240L5-1, 240L5-2, 240L5-3, and 240L5-4, which correspond one-to-one with the four first ground lines 121L5A. The first analog-to-digital converter 220L5 has four detection channels (A, B, C, and D), which correspond one-to-one with the four first signal lines 121L5B. During the period when first switches 240L5-1, 240L5-2, and 240L5-3 are closed, only the first three detection channels (A, B, and C) of the first analog-to-digital converter 220L5 can obtain detection signals. During the period when first switch 240L5-4 is closed, all detection channels (A, B, C, and D) of the first analog-to-digital converter 220L5 can obtain detection signals. This embodiment also includes an electric field generator (not shown) similar to the third and fourth embodiments.
[0111] FIG8 shows a schematic block diagram of an electrode sheet 100L6 and a first adapter 200L6 in an electric field therapy system according to a sixth embodiment of the present disclosure. The electrode sheet 100L6 of the electric field therapy system of this embodiment includes nine electrode units 110L6. Compared to the corresponding electrode sheet of the electric field therapy system of the fifth embodiment, only the first three groups of electrode units 110L6 are provided in this embodiment, and the fourth group of electrode units 110L6 is not provided. In this embodiment, each of the three groups of electrode units 110L6 includes three electrode units 110L6. In this embodiment, the flexible circuit board 120L6 of the electrode sheet 100L6, which is composed of a flexible circuit board, is embedded with three first ground lines 121L6A, three first signal lines 121L6B, and one first AC line 121L6C. First signal lines 121L6B-1, 121L6B-2, and 121L6B-3 are each connected to the signal terminal 114L6B of the temperature detector 114L6 of a corresponding electrode unit 110L6 in each of the three groups of electrode units 110L6. Three first ground lines 121L6A are each connected to the ground terminals 114L6A of all temperature detectors 114L6 in a corresponding group of electrode units 110L6. Similar to the previous embodiment, in this embodiment, the ground terminals 114L6A of multiple temperature detectors 114L6 in the same group of electrode units 110L6 are short-circuited via the same first ground line 121L6A on the flexible printed circuit board 120L6. The ground terminals 114L6A of multiple corresponding temperature detectors 114L6 in different groups are connected in parallel via different first ground lines 121L6A on the flexible printed circuit board 120L6. The signal ends 114L6B of the plurality of temperature detectors 114L6 located in the same group of electrode units 110L6 are connected in parallel via different first signal lines 121L6B of the flexible circuit board 120L6, and the signal ends 114L6B of the plurality of corresponding temperature detectors 114L6 located in different groups are short-circuited via the same first signal line 121L6B of the flexible circuit board 120L6.
[0112] In this embodiment, the first cable (not shown) has seven conductors. The seven conductors of the first cable (not shown) are connected one-to-one with three first ground lines 121L6A, three first signal lines 121L6B, and one first AC line 121L6C embedded in the flexible circuit board 120L6.
[0113] The first adapter 200L6 of this embodiment has the same first controller 210L6 and first communication transceiver 250L6 as the first adapter of the previous embodiment. Each group of first switches 240L6 of the first adapter 200L6 of this embodiment has the same structure as each group of first switches of the first adapter of the third and fourth embodiments, but each group is provided with three first switches 240L6. In this embodiment, each group of first switches 240L6-1, 240L6-2, and 240L6-3 of the first adapter 200L6 corresponds one-to-one with the three first ground lines 121L6A of the corresponding electrode sheet 100L6. The first analog-to-digital converter 220L6 has three detection channels (A, B, C) that correspond one-to-one with the three first signal lines 121L6B of the corresponding electrode sheet 100L6. During the period when any first switch 240L6 is closed, all detection channels (A, B, C) of the first analog-to-digital converter 220L6 can obtain detection signals. This embodiment also has the same electric field generator (not shown) as the third and fourth embodiments.
[0114] Each electrode unit of the electrode sheet of the present invention, such as 100L1 to 100L6, such as 110L1 to 110L6, includes a temperature detector, such as 114L1 to 114L6. The temperature detectors, such as 114L1 to 114L6, of a corresponding group of electrode units, such as 110L1 to 110L6, can be grounded in sequence through each first grounding line, such as 121L1A to 121L6A. A signal line such as 121L1B to 121L6B electrically connects at most one electrode unit such as 110L1 to 110L6 in each group of electrode units such as 110L1 to 110L6 to a temperature detector such as 114L1 to 114L6, so that multiple first signal lines such as 121L1B to 121L6B can acquire detection signals from multiple temperature detectors such as 114L1 to 114L6 in a time-sharing manner, thereby making the patient's body surface temperature detection more comprehensive and accurate. At the same time, the above-mentioned line connection reduces the number of wires in the first cable connecting the electrode sheets such as 100L1 to 100L6. The number of wires in the first cable is no more than 10, which effectively reduces the overall weight of the electrode sheets such as 100L1 to 100L6 and prevents the adhesion effect between the electrode sheets such as 100L1 to 100L6 and the corresponding body surface of the patient's tumor site due to the increase in the number of wires in the first cable.
[0115] The present disclosure also provides a control method for an electric field therapy system. Taking the electric field therapy system shown in FIG2 as an example, the method includes: sequentially and individually conducting each first grounding line 121L1A of the electrode sheet 100L1; while each first grounding line 121L1A is conducting, obtaining a detection signal from a temperature detector 114L1 of each electrode unit 110L1 in a group of electrode units 110L1 grounded by the first grounding line 121L1A, received by a first adapter 200L1; and adjusting the alternating electric signal applied to each electrode unit 110L1 based on the obtained detection signal.
[0116] FIG9 is a flow chart of a control method for an electric field therapy system according to an embodiment of the present disclosure. Taking the electric field therapy system shown in FIG2 as an example, as shown in FIG9, the method includes the following steps:
[0117] S101, the first controller 210L1 of the first adapter 200L1 simultaneously controls four first switches 240L1 of a group of first switches 240L1 among the multiple groups of first switches 240L1, so that one first switch 240L1 among the four first switches 240L1 (first switches 240L1-1, 240L1-2, 240L1-3 and 240L1-4) is turned on, and the remaining three first switches 240L1 are turned off.
[0118] S102, one group of first analog-to-digital converters 220L1 in the multiple groups of first analog-to-digital converters 220L1 of the first adapter 200L1 collects detection signals of multiple temperature detectors 114L1 short-circuited with the turned-on first switch 240L1 through its corresponding detection channel, and the detection signals are voltage analog signals.
[0119] S103 , one group of first analog-to-digital converters 220L1 among the multiple groups of first analog-to-digital converters 220L1 of the first adapter 200L1 converts the collected voltage analog signal into a digital temperature signal.
[0120] S104 , the first communication transceiver 250L1 of the first adapter 200L1 transmits the digital temperature signal in series to the electric field generator 300L1 .
[0121] Repeat S101-S104 so that the voltage analog signal detected by each temperature detector 114L1 of the electrode sheet 100L1 is collected by the first adapter 200L1 and converted into a digital temperature signal, and then transmitted to the electric field generator 300L1. Specifically, when only the first switch 240L1-1 is closed, all detection channels AE of the first analog-to-digital converter 220L1 will respectively collect the detection signals of the temperature detectors 114L1 of the electrode units 110L1-1 to 110L1-5; when only the first switch 240L1-2 is closed, all detection channels AE of the first analog-to-digital converter 220L1 will respectively collect the detection signals of the temperature detectors 114L1 of the electrode units 110L1-6 to 110L1-10. When only the first switch 240L1-3 is closed, all detection channels AE of the first analog-to-digital converter 220L1 will respectively collect detection signals from the temperature detectors 114L1 of electrode units 110L1-11 to 110L1-15; when only the first switch 240L1-4 is closed, all detection channels AE of the first analog-to-digital converter 220L1 will respectively collect detection signals from the temperature detectors 114L1 of electrode units 110L1-16 to 110L1-20. The specific operating principle is detailed in the relevant description of FIG2 and will not be repeated here. In this way, the electric field generator 300L1 can obtain analog temperature signals detected by all temperature detectors 114L1 on the electrode sheet 100L1.
[0122] After the electric field generator 300L1 obtains the digital temperature signals of all temperature detectors 114L1 of the corresponding electrode sheet 100L1, the following steps are also included: the electric field generator 300L1 compares the preset temperature threshold set therein with all the obtained digital temperature signals and adjusts the alternating electric signal applied to each electrode unit of the corresponding electrode sheet 100L1 according to the comparison result.
[0123] The preset temperature threshold is 37-42°C. The aforementioned adjustment of the alternating electrical signal applied to each electrode unit of the corresponding electrode sheet 100L1 according to the comparison result is specifically as follows: when all digital temperature signals are lower than the preset temperature threshold, the voltage of the alternating electrical signal applied to each electrode unit 110L1 of the corresponding electrode sheet 100L1 is maintained or increased; when a certain digital temperature signal is equal to or higher than the preset temperature threshold, the alternating voltage applied to each electrode unit 110L1 of the corresponding electrode sheet 100L1 is reduced to 0.
[0124] Each electrode unit 110L1 of the multiple groups of electrode units 110L1 of the electrode sheet 100L1 disclosed in the present invention includes a temperature detector 114L1, and the temperature detector 114L1 of a corresponding group of electrode units 110L1 in the multiple groups of electrode units 110L1 is grounded in turn through each first grounding line 121L1A, and the temperature detector 114L1 of at most one electrode unit 110L1 in each group of electrode units 110L1 is electrically connected through each first signal line 121L1B. It is possible to obtain the detection signals of each temperature detector 114L1 of different groups of electrode units 110L1 of the electrode sheet through each first signal line 121L1B in a time-sharing manner, thereby making the patient's body surface temperature detection more comprehensive and accurate.
[0125] Second embodiments
[0126] 10-12 , the electric field therapy system includes at least one pair of electrode sheets 100L7, a first adapter 200L7, and an electric field generator 300L7. The at least one pair of electrode sheets 100L7 can be placed on the patient's body surface in pairs. For example, as shown in FIG10 , four electrode sheets 100L7 are placed on the patient's body surface as a pair of two electrode sheets 100L7. The first adapter 200L7 is electrically connected to each electrode sheet 100L7, and the electric field generator 300L7 is electrically connected to the first adapter 200L7. The electric field generator 300L7 generates an alternating electrical signal for a tumor electric field and transmits the alternating electrical signal to each electrode sheet 100L7 via the first adapter 200L7, thereby applying an alternating electric field to the patient's tumor site for tumor therapy.
[0127] The electrode sheet 100L7 includes a flexible circuit board 120L7, a plurality of electrode elements 112L7, and a plurality of temperature sensors 114L7 disposed on the flexible circuit board 120L7. Each electrode element 112L7 is capable of applying an alternating electric field. Each temperature sensor 114L7 is provided corresponding to an electrode element 112L7 to detect the temperature at the corresponding electrode element 112L7. The electrode sheet 100L7 also includes a first cable 130L7 connected to the flexible circuit board 120L7. A first connector 180L7 is provided between each electrode sheet 100L7 and the first adapter 200L7. The first connector 180L7 is adapted to connect the corresponding electrode sheet 100L7 to the first adapter 200L7. The first connector 180L7 is a plug, disposed at the end of the first cable 130L7 of the corresponding electrode sheet 100L7 away from the flexible circuit board 120L7. The first adapter 200L7 is provided with a plurality of first sockets 260L7 corresponding to the plurality of first connectors 180L7. The first plugs and the first sockets 260L7 are press-type spring connectors, that is, the first connector 180L7 connects the first adapter 200L7 to the electrode sheet 100L7 in a connector manner.
[0128] The flexible circuit board 120L7 of the electrode sheet 100L7 is arranged in a grid pattern. Multiple electrode elements 112L7 and multiple temperature sensors 114L7 are spaced apart on the flexible circuit board 120L7. Each electrode element 112L7 has a through-hole 1120L7, which is suitable for mounting a temperature sensor 114L7. In this embodiment, the opening 1120L7 is located in the center of each electrode element 112L7, and each temperature sensor 114L7 is received within the opening 1120L7 of the corresponding electrode element 112L7. Optionally, the electrode elements 112L7 are dielectric elements, such as ceramic sheets, or polymer dielectric layers disposed on the flexible circuit board 120L7. The temperature sensors 114L7 may also be located elsewhere on the electrode elements 112L7.
[0129] Multiple electrode elements 112L7 and multiple temperature detectors 114L7 constitute multiple electrode units 110L7. The multiple electrode elements 112L7 are generally arranged in an array. As shown in FIG10 , the 20 electrode elements 112L7 are arranged in four rows and six columns. The first and fourth rows each contain four electrode elements 112L7, and the four electrode elements 112L7 in each of the first and fourth rows are located in columns 2 through 5. The middle two rows each contain six electrode elements 112L7, and the six electrode elements 112L7 in each of the middle two rows are located in columns 1 through 6. The 20 electrode elements 112L7 can also be arranged in four rows and five columns, with each row containing five electrode elements 112L7. The spatial arrangement of the multiple temperature detectors 114L7, which are arranged in a one-to-one correspondence with the electrode elements 112L7, is roughly the same as the array arrangement of the multiple electrode elements 112L7.
[0130] Referring to Figure 11 , multiple electrode elements 112L7 are connected in parallel via a common first AC line 121L7C on a flexible circuit board 120L7. Alternating electrical signals are transmitted via the first AC line 121L7C, forming a therapeutic electric field with the opposing electrode pads 100L7 for tumor treatment. The multiple electrode elements 112L7 and the multiple temperature sensors 114L7 are arranged in multiple rows and columns. This means that the multiple electrode units 110L7 are also arranged in multiple rows and columns. In this embodiment, the 20 electrode elements 112L7 are arranged in the order of detection bits 1 to 20, forming four rows and five columns. Since the multiple temperature sensors 114L7 correspond one-to-one with the multiple electrode elements 112L7, the multiple temperature sensors 114L7 are also arranged in four rows and five columns. It should be noted that the arrangement here is to more clearly illustrate the electrical connection between the electrode sheet 100L7 and the first adapter 200L7, and does not represent the arrangement of the electrode element 112L7 in a spatial structure, the spatial structure of which may be a roughly array structure as shown in FIG. 10 .
[0131] Each temperature detector 114L7 has a signal terminal 114L7B and a ground terminal 114L7A. The signal terminals 114L7B of the corresponding temperature detectors 114L7 in each column group are connected together as temperature sampling points. The ground terminals 114L7A of the corresponding temperature detectors 114L7 in each row group are grounded together through a first switch 240L7. The ground terminals 114L7A of the corresponding temperature detectors 114L7 in different row groups are grounded through different first switches 240L7, so that the detection signals of the corresponding temperature detectors 114L7 in each row group can be sampled simultaneously by the corresponding temperature sampling points by configuring the opening and closing states of the first switch 240L7. The sampled detection signals of each temperature detector 114L7 are used to characterize the type of the electrode sheet 100L7. As shown in FIG11 , in this embodiment, the ground terminals 114L7A of the five temperature detectors 114L7 in each row group are short-circuited in parallel via a common first ground line 121L7A of the flexible circuit board 120L7. The signal terminals 114L7B of the five temperature detectors 114L7 in each row group are connected in parallel via five first signal lines 121L7B of the flexible circuit board 120L7. The signal terminals 114L7B of the temperature detectors 114L7 in each column group are short-circuited in parallel via a common first signal line 121L7B of the flexible circuit board 120L7. The ground terminals 114L7A of the temperature detectors 114L7 in each column group are connected in parallel via four first ground lines 121L7A of the flexible circuit board 120L7.
[0132] 11 , each temperature detector 114L7 is further connected in series with a first diode 115L7. Temperature detector 114L7 has a signal terminal 114L7B and a ground terminal 114L7A. First diode 115L7 has an anode 115L7B and a cathode 115L7A. Anode 115L7B of first diode 115L7 is connected to ground terminal 114L7A of temperature detector 114L7, while cathode 115L7A of first diode 115L7 is connected to a corresponding first ground line 121L7A. Signal terminal 114L7B of temperature detector 114L7 is connected to a corresponding first signal line 121L7B. When detecting temperature, the first diode 115L7 prevents the resistance of other temperature detectors 114L7 from affecting the detection signal.
[0133] 11-12 , the first adapter 200L7 includes a main control board electrically connected to the first connector 180L7. The main control board includes a first controller 210L7, a first analog-to-digital converter 220L7, multiple sets of first switches 240L7, and a first communication transceiver 250L7. The first controller 210L7 is used to configure the on / off states of the multiple sets of first switches 240L7. The first analog-to-digital converter 220L7 is connected to the first controller 210L7. The first analog-to-digital converter 220L7 is used to simultaneously sample the detection signals of the corresponding temperature detectors 114L7 in each row group through corresponding temperature sampling points to obtain a plurality of analog-to-digital (A / D) sampling values. The A / D sampling values are then sent to the first controller 210L7 so that the first controller 210L7 can identify the type of the corresponding electrode sheet 100L7 based on the A / D sampling values.
[0134] In this embodiment, the first controller 210L7 selectively controls the on and off of any one of the multiple first switches 240L7 to selectively enable any row group of temperature detectors 114L7 among the 20 temperature detectors 114L7 to detect the temperature of the electrode sheet 100L7. The first analog-to-digital converter 220L7 simultaneously collects the detection signals of the group of temperature detectors 114L7 through the corresponding temperature sampling points to obtain a number of AD sampling values, converts the AD sampling values to obtain digital signals, and transmits the AD sampling values to the first controller 210L7, so that the first controller 210L7 can identify the type of the corresponding electrode sheet 100L7 based on the several AD sampling values.
[0135] The first ADC 220L7 has multiple detection channels, and the number of detection channels is greater than or equal to the number of column groups. In this embodiment, as shown in FIG11 , the first ADC 220L7 has five detection channels, A, B, C, D, and E. Each detection channel simultaneously collects the detection signal of only one corresponding temperature detector 114L7 to obtain an AD sampled value. This AD sampled value is a voltage value, meaning that the detection signal is a voltage value. Only one of the four first switches 240L7 is turned on at a time, while the other three are turned off. This allows the first ADC 220L7 to collect the detection signals of the group of temperature detectors 114L7 that are short-circuited with the turned-on first switch 240L7. Specifically, as shown in FIG11 , the ground terminals 114L7A of the temperature detectors 114L7 numbered 1, 2, 3, 4, and 5 are short-circuited together and grounded through the first switch 240L7-1 in the first adapter 200L7, and the signal terminals 114L7B of the temperature detectors 114L7 numbered 1, 2, 3, 4, and 5 are connected to the detection channels AE of the first analog-to-digital converter 220L7 through corresponding temperature sampling points; the ground terminals 114L7A of the temperature detectors 114L7 numbered 6, 7, 8, 9, and 10 are short-circuited together and grounded through the first switch 240L7-2 in the first adapter 200L7, and the signal terminals 114L7B of the temperature detectors 114L7 numbered 6, 7, 8, 9, and 10 are connected to the detection channels AE of the first analog-to-digital converter 220L7 through corresponding temperature sampling points; The ground terminals 114L7A of the temperature detectors 114L7 numbered 11, 12, 13, 14, and 15 are short-circuited together and grounded through the first switch 240L7-3 in the first adapter 200L7. The signal terminals 114L7B of the temperature detectors 114L7 numbered 11, 12, 13, 14, and 15 are respectively connected to the detection channels AE of the first analog-to-digital converter 220L7 through the corresponding temperature sampling points; the ground terminals 114L7A of the temperature detectors 114L7 numbered 16, 17, 18, 19, and 20 are short-circuited together and grounded through the first switch 240L7-4 in the first adapter 200L7. The signal terminals 114L7B of the temperature detectors 114L7 numbered 16, 17, 18, 19, and 20 are respectively connected to the detection channels AE of the first analog-to-digital converter 220L7 through the corresponding temperature sampling points. At the same time, each temperature sampling point is connected to the DC power supply VCC via a corresponding first voltage dividing resistor 230L7 in the first adapter 200L7.
[0136] As shown in Figure 10, a second connector 280L7 is provided between the first adapter 200L7 and the electric field generator 300L7. The second connector 280L7 is suitable for connecting the electric field generator 300L7 to the first adapter 200L7. The first adapter 200L7 also includes a second cable 270L7 connected to the second connector 280L7. The second connector 280L7 is a second plug, and the electric field generator 300L7 is provided with a second socket 310L7 corresponding to the second connector 280L7. The second plug and the second socket 310L7 are press-type spring connectors, meaning that the second connector 280L7 connects the first adapter 200L7 to the electric field generator 300L7 using a connector-type design. As shown in Figures 10-12 , each of the first connectors 180L7-X1, 180L7-Y1, 180L7-X2, and 180L7-Y2 is connected to the second connector 280L7 via an AC line. The first connectors 180L7-X1, 180L7-Y1, 180L7-X2, and 180L7-Y2 are also connected to multiple sets of first switches 240L7 and the first analog-to-digital converter 220L7, respectively. The second connector 280L7 is connected to the first communication transceiver 250L7 via a receive data line RX and a transmit data line TX. The VCC pin of the second connector 280L7 is connected to the power supply terminal of the first controller 210L7, and the GND pin of the second connector 280L7 is grounded. The VCC pin of the second connector 280L7 is also connected to a temperature sampling point via a corresponding first voltage divider resistor 230L7.
[0137] The first controller 210L7 is connected to multiple groups of first switches 240L7 and is connected between the first analog-to-digital converter 220L7 and the first communication transceiver 250L7. The first controller 210L7 can also send a number of AD sampling values to the electric field generator 300L7 via the first communication transceiver 250L7, so that the electric field generator 300L7 can identify the type of the corresponding electrode sheet 100L7 based on the number of AD sampling values when the electrode sheet is normal. In other words, when the electrode sheet is normal, the first controller 210L7 or the electric field generator 300L7 can determine the type of the corresponding electrode sheet 100L7 based on the AD sampling values.
[0138] Optionally, the temperature detector 114L7 is a thermistor. For example, the temperature detector 114L7 is a thermistor with a negative temperature coefficient, which has the characteristic that the higher the temperature, the smaller the resistance, and the lower the temperature, the larger the resistance. Since the electrode sheet 100L7 is applied to the human body surface during use, and the human body surface temperature is generally between 36°C and 37°C, a thermistor with a negative temperature coefficient in the temperature range of 0°C to 50°C can be selected. For example, a thermistor model NCP18XH103D03RB can be selected. When the temperature it senses is 0°C, the corresponding resistance is approximately 27.45KΩ; when the temperature it senses is 25°C, the corresponding resistance is approximately 10.0KΩ; and when the temperature it senses is 50°C, the corresponding resistance is approximately 4.16KΩ. In other embodiments, the temperature detector 114L7 is a thermistor with a positive temperature coefficient.
[0139] As shown in FIG11 and FIG13, when the first controller 210L7 controls any one of the plurality of first switches 240L7 to be turned on, the DC power supply VCC sequentially provides DC power to the first voltage-dividing resistor 230L7, the temperature detector 114L7, and the first diode 115L7. The first analog-to-digital converter 220L7 in the first adapter 200L7 collects the voltage between the temperature detector 114L7 and the first voltage-dividing resistor 230L7 through the corresponding detection channel, that is, the voltage divided by the temperature detector 114L7, the first diode 115L7, and the first voltage-dividing resistor 230L7, and obtains an AD sampling value, that is, a voltage value (voltage value of the thermistor), as shown in the following formula (1): VADC = (VCC - VD) × R / (Rz + R) (1)
[0140] Among them, VADC is the AD sampling value, that is, the voltage value, VCC is also used to represent the voltage of the DC power supply, VD is the voltage drop of the first diode 115L7, R is the resistance of the thermistor, and Rz is the resistance of the first voltage divider resistor 230L7.
[0141] Assuming that the voltage drop VD of the first diode 115L7 is 0.3V and the resistance Rz of the first voltage divider resistor 230L7 is 10KΩ, then when the temperature sensed by the temperature detector 114L7 is 0°C, the corresponding resistance is approximately 27.45KΩ. Based on formula (1), the corresponding AD sampling value V0 = (3.3-0.3) × 27.45 / (10 + 27.45) = 2.20V can be obtained; when the temperature sensed by the temperature detector 114L7 is 25 When the temperature sensed by the temperature detector 114L7 is 50°C, the corresponding resistance value is approximately 10.0KΩ. Based on formula (1), the corresponding AD sampling value V25 = (3.3-0.3) × 10 / (10+10) = 1.50V can be obtained. When the temperature sensed by the temperature detector 114L7 is 50°C, the corresponding resistance value is approximately 4.16KΩ. Based on formula (1), the corresponding AD sampling value V50 = (3.3-0.3) × 4.16 / (10+4.16) = 0.88V can be obtained. When the temperature detector 114L7 is disconnected, for example, the temperature detector 114L7 is not welded or the temperature detector 114L7 is short-circuited, the corresponding AD sampling value can be 3.3V. When the temperature detector 114L7 and the first diode 115L7 are short-circuited, the corresponding AD sampling value can be 0V.
[0142] Since the first analog-to-digital converter 220L7 collects the voltage value of the temperature detector 114L7, and the temperature detector 114L7 has corresponding different voltage values for different temperatures, the voltage value collected by the first analog-to-digital converter 220L7 can be reasonably segmented for distinction, and the voltage value can be converted into a corresponding code, that is, different voltage intervals of the voltage value correspond to different codes. Based on the code, the code array of the electrode sheet 100L7 can be determined. The code array includes at least one of the first code, the second code, and the third code, wherein the first code is used to indicate that the temperature detector 114L7 is in a normal state, the second code is used to indicate that the temperature detector 114L7 is in an open circuit state or an unset state, and the third code is used to indicate that the temperature detector 114L7 is in a short circuit state. The code array is used to identify the type of the electrode sheet 100L7, that is, the number of electrode elements 112L7 on the electrode sheet 100L7.
[0143] Specifically, taking the temperature detector 114L7 sensing the temperature within the range of 0℃~50℃, and the AD sampling value obtained by the first analog-to-digital converter 220L7, that is, the voltage value range is 0.88V~2.20V as an example, considering the detection error factors, etc., the voltage value range can be appropriately enlarged to 0.5V~3V.
[0144] When the AD sampled value obtained by the first analog-to-digital converter 220L7 is greater than 0.5V and less than 3V, the corresponding code is a first code, such as 1; when the AD sampled value obtained by the first analog-to-digital converter 220L7 is less than or equal to 0.3V, the corresponding code is a third code, such as 0; and when the AD sampled value obtained by the first analog-to-digital converter 220L7 is greater than or equal to 3.1V, the corresponding code is a second code, such as 2. Therefore, in the corresponding detection bits numbered 1 to 20 of the electrode sheet 100L7, if the temperature detector 114L7 is short-circuited, the corresponding code is a third code, such as 0; if the temperature detector 114L7 is normal, the corresponding code is a first code, such as 1; and if there is no temperature detector 114L7 or the temperature detector 114L7 is disconnected, the corresponding code is a second code, such as 2.
[0145] When sampling, no matter which type of electrode sheet 100L7 is used (i.e., the number of electrode elements 112L7 or temperature detectors 114L7 of the electrode sheet 100L7 is any number less than or equal to 20), the first analog-to-digital converter 220L7 obtains 20 AD sampling values each time it collects, and after each collection is completed, a 20-bit coding array is formed based on the 20 AD sampling values. Each type of electrode sheet 100L7 has a corresponding preset coding array, so the type of the electrode sheet 100L7 can be automatically identified by comparing the coding array obtained by collection with the preset coding array.
[0146] The first controller 210L7 can determine the coding array of the corresponding electrode sheet 100L7 according to a number of AD sampling values, and determine the type of the corresponding electrode sheet 100L7 according to the coding array.
[0147] As shown in Figure 11, under normal circumstances, when the electrode sheet 100L7 has 20 electrode elements 112L7, that is, the corresponding detection positions numbered 1 to 20 of the electrode sheet 100L7 all have temperature detectors 114L7, and the codes are all 1, the 20 codes are combined to obtain a 20-bit code array 11111 11111 11111 11111.
[0148] As shown in Figure 14, when the electrode sheet 100L7 has 9 electrode elements 112L7 and 9 temperature detectors 114L7, that is, when it has 9 electrode units 110L7, the 9 electrode elements 112L7 and the 9 temperature detectors 114L7 are arranged in two rows and five columns in the circuit connection, and the 9 electrode elements 112L7 and the 9 temperature detectors 114L7 are arranged sequentially, and a corresponding position of the 9 temperature detectors 114L7 is short-circuited with a wire (unnumbered), that is, a wire (unnumbered) is set at the intersection of the two rows and five columns in the circuit connection to short-circuit the ground terminal 114L7A of the temperature detector 114L7 in the same row group, and at the same time short-circuit the signal terminal 114L7B of the temperature detector 114L7 in the same column group. The detection bits corresponding to each electrode element 112L7 are numbered 1 to 9, that is, the detection bits corresponding to numbers 1 to 9 of the electrode sheet 100L7 all have temperature detectors 114L7, and the codes are all 1. The difference from the electrode sheet 100L7 with 20 electrode elements 112L7 shown in Figure 11 is that the next detection bit (that is, the corresponding detection bit number 10) has no electrode element 112L7 (no temperature detector 114L7) set, and is short-circuited by a wire (unnumbered), and the corresponding code is 0; the corresponding detection bits numbered 11 to 20 have no electrode element 112L7 (no temperature detector 114L7) set, nor are they short-circuited by a wire (unnumbered), and are in a disconnected state, and the corresponding code is 2. Therefore, the 20-bit codes are combined to obtain a 20-bit code array 11111 11110 22222 22222.
[0149] As shown in Figure 15, when the electrode sheet 100L7 has 13 electrode elements 112L7 and 13 temperature detectors 114L7, the 13 electrode elements 112L7 and the 13 temperature detectors 114L7 are arranged in three rows and five columns in the circuit connection, and the 13 electrode elements 112L7 and the 13 temperature detectors 114L7 are arranged sequentially, and a corresponding position of the 13 temperature detectors 114L7 is short-circuited with a wire (unnumbered), that is, a wire (unnumbered) is set at the intersection of the three rows and four columns in the circuit connection to short-circuit the ground terminal 114L7A of the temperature detector 114L7 in the same row group, and at the same time short-circuit the signal terminal 114L7B of the temperature detector 114L7 in the same column group. The detection bits corresponding to each electrode element 112L7 are numbered 1 to 13, that is, the detection bits corresponding to numbers 1 to 13 of the electrode sheet 100L7 all have temperature detectors 114L7, and the codes are all 1. The difference from the electrode sheet 100L7 with 20 electrode elements 112L7 shown in Figure 11 is that the next detection bit (that is, the corresponding detection bit number 14) has no electrode element 112L7 (no temperature detector 114L7) set, and is short-circuited in parallel by wires (unnumbered), and the corresponding code is 0; the corresponding detection bits numbered 15 to 20 have no electrode element 112L7 (no temperature detector 114L7) set, nor are they short-circuited in parallel by wires (unnumbered), and are in a disconnected state, and the corresponding code is 2. Therefore, the 20-bit codes are combined to obtain a 20-bit code array of 11111 11111 11102 22222.
[0150] As shown in Figure 16, when the electrode sheet 100L7 has 19 electrode elements 112L7 and 19 temperature detectors 114L7, the 19 electrode elements 112L7 and the 19 temperature detectors 114L7 are arranged in four rows and five columns in the circuit connection, and the 19 electrode elements 112L7 and the 19 temperature detectors 114L7 are arranged sequentially, and a corresponding position of the 19 temperature detectors 114L7 is short-circuited with a wire (unnumbered), that is, a wire (unnumbered) is set at the intersection of the four rows and five columns in the circuit connection to short-circuit the ground terminal 114L7A of the temperature detector 114L7 in the same row group, and at the same time short-circuit the signal terminal 114L7B of the temperature detector 114L7 in the same column group. The detection bits corresponding to each electrode element 112L7 are numbered 1 to 19, that is, the detection bits corresponding to the numbers 1 to 19 of the electrode sheet 100L7 all have a temperature detector 114L7, and the codes are all 1. The difference from the electrode sheet 100L7 with 20 electrode elements 112L7 shown in FIG11 is that the electrode element 112L7 is not set at the position of the next detection bit (that is, the corresponding detection bit number 20) (no temperature detector 114L7 is set), and it is short-circuited in parallel by wires (unnumbered), and the corresponding code is 0. Therefore, the 20-bit codes are combined to obtain a 20-bit code array of 11111 11111 11111 11110.
[0151] When the first adapter 200L7 is not connected to the electrode sheet 100L7, the voltage collected by the first analog-to-digital converter 220L7 is 3.3V of the DC power supply VCC, so the 20-bit code array obtained is 22222 22222 22222 22222.
[0152] Based on the above rules, it can be seen that the electrode sheet 100L7 with 1 electrode element 112L7 and 1 temperature detector 114L7 corresponds to a coding array of 10222 22222 22222 22222; the electrode sheet 100L7 with 2 electrode elements 112L7 and 2 temperature detectors 114L7 corresponds to a coding array of 11022 22222 22222 22222; the electrode sheet 100L7 with 3 electrode elements 112L7 and 3 temperature detectors 114L7 corresponds to a coding array of 11102 22222 22222 22222; the electrode sheet 100L7 with 4 electrode elements 112L7 and 4 temperature detectors 114L7 corresponds to a coding array of 11110 22222 22222 22222; the electrode sheet 100L7 with 5 electrode elements 112L7 and 5 temperature detectors 114L7, the corresponding coding array is 11111 02222 22222 22222; the electrode sheet 100L7 with 6 electrode elements 112L7 and 6 temperature detectors 114L7, the corresponding coding array is 11111 10222 22222 22222; the electrode sheet 100L7 with 7 electrode elements 112L7 and 7 temperature detectors 114L7, the corresponding coding array is 11111 11022 22222 22222; the electrode sheet 100L7 with 8 electrode elements 112L7 and 8 temperature detectors 114L7, the corresponding coding array is 11111 11102 22222 22222; the electrode sheet 100L7 with 9 electrode elements 112L7 and 9 temperature detectors 114L7, the corresponding coding array is 11111 11110 22222 22222; the electrode sheet 100L7 with 10 electrode elements 112L7 and 10 temperature detectors 114L7, the corresponding coding array is 11111 11111 02222 22222; the electrode sheet 100L7 with 11 electrode elements 112L7 and 11 temperature detectors 114L7, the corresponding coding array is 11111 11111 10222 22222; the electrode sheet 100L7 with 12 electrode elements 112L7 and 12 temperature detectors 114L7, the corresponding coding array is 11111 11111 11022 22222; the electrode sheet 100L7 having 13 electrode elements 112L7 and 13 temperature detectors 114L7, the corresponding coding array is 11111 11111 11102 22222; the electrode sheet 100L7 having 14 electrode elements 112L7 and 14 temperature detectors 114L7, the corresponding coding array is 11111 11111 11110 22222;The electrode sheet 100L7 having 15 electrode elements 112L7 and 15 temperature detectors 114L7 has a corresponding coding array of 11111 11111 11111 02222; the electrode sheet 100L7 having 16 electrode elements 112L7 and 16 temperature detectors 114L7 has a corresponding coding array of 11111 11111 11111 10222; the electrode sheet 100L7 having 17 electrode elements 112L7 and 17 temperature detectors 114L7 has a corresponding coding array of 11111 11111 11111 11022; the electrode sheet 100L7 having 18 electrode elements 112L7 and 18 temperature detectors 114L7 has a corresponding coding array of 11111 11111 11111 11102; For an electrode sheet 100L7 having 19 electrode elements 112L7 and 19 temperature sensors 114L7, the corresponding coding array is 11111 11111 11111 11110; For an electrode sheet 100L7 having 20 electrode elements 112L7 and 20 temperature sensors 114L7, the corresponding coding array is 11111 11111 11111 11111; When the first adapter 200L7 is not connected to the electrode sheet 100L7, the corresponding coding array is 22222 22222 22222 22222.
[0153] The above 21 number arrays are all different. Therefore, if the electrode sheet 100L7 is normal, the first controller 210L7 can use the code array to determine the type of electrode sheet 100L7 connected to the first adapter 200L7 or whether the electrode sheet 100L7 is connected. It should be noted that the electric field generator 300L7 uses the same method to determine the type of electrode sheet 100L7 connected to the first adapter 200L7 or whether the electrode sheet 100L7 is connected. The details will not be repeated here.
[0154] When the type of electrode sheet 100L7 is determined, the first controller 210L7 also determines whether the corresponding electrode sheet 100L7 has a temperature detection fault based on the coding array, wherein the detection signal of each temperature detector 114L7 sampled is also used to characterize whether the electrode sheet 100L7 has a temperature detection fault.
[0155] As shown in Figure 10, in the electrode sheet 100L7 having 20 electrode elements 112L7 and 20 temperature detectors 114L7, assuming that the temperature detector 114L7 numbered 20 is damaged (disconnected), the AD sampling value obtained by the first analog-to-digital converter 220L7 is 3.3V, the corresponding sampling code is the second code 2, and the corresponding abnormal code array is 11111 11111 11111 11112, which is inconsistent with the standard code array 11111 11111 11111 11111, so the first controller 210L7 can distinguish the temperature detection failure.
[0156] As shown in Figure 14, in the electrode sheet 100L7 having 9 electrode elements 112L7 and 9 temperature detectors 114L7, it is assumed that the temperature detector 114L7 numbered 1 is damaged (disconnected), the AD sampling value obtained by the first analog-to-digital converter 220L7 is 3.3V, the corresponding sampling code is the second code 2, and the corresponding abnormal code array is 21111 11110 22222 22222, which is inconsistent with the standard code array 11111 11110 22222 22222, so the first controller 210L7 can distinguish the temperature detection failure.
[0157] In summary, when the temperature detector 114L7 of the electrode sheet 100L7 is normal, the code "0" in the corresponding 20-bit code array is not the last digit, and the codes before the code "0" are all "1", and the codes after the code "0" are all "2"; or, the code "0" is the last digit and the codes before the code "0" are all "1"; or, all codes in the 20-bit code array are "1". When the temperature detector 114L7 of the electrode sheet 100L7 is damaged, regardless of whether the code "0" in the corresponding 20-bit code array is the last digit, the code before the code "0" is a code different from "1" (code "2"), or all codes in the 20-bit code array are "1" or "2".
[0158] The present disclosure also provides a tumor treatment device (not shown), comprising: at least one pair of the aforementioned electrode sheets 100L7, or the aforementioned electric field treatment system.
[0159] According to the tumor treatment device (not shown) of the embodiment of the present disclosure, the aforementioned electrode sheet 100L7 or electric field therapy system can automatically identify the type of electrode sheet 100L7 when the electrode sheet 100L7 is normal, thereby realizing temperature acquisition of different types of electrode sheets 100L7 without missing acquisition or generating interference signals. When the type of electrode sheet 100L7 is determined, it can be determined whether the corresponding electrode sheet 100L7 has a temperature detection failure.
[0160] The present disclosure also provides a computer-readable storage medium (not shown) on which an electrode patch recognition program for an electric field therapy system is stored. When the electrode patch recognition program for an electric field therapy system is executed by a processor (not shown), the aforementioned electrode patch recognition of the electric field therapy system is realized.
[0161] According to the computer-readable storage medium (not shown) of the embodiment of the present disclosure, when the electrode sheet 100L7 is normal, the type of the electrode sheet 100L7 can be automatically identified, thereby realizing temperature acquisition of different types of electrode sheets 100L7 without missing acquisition or generating interference signals. When the type of the electrode sheet 100L7 is determined, it can be determined whether the corresponding electrode sheet 100L7 has a temperature detection failure.
[0162] The present disclosure also provides a first adapter 200L7 of an electric field therapy system, comprising a memory, a processor (not shown), and an electrode patch recognition program of the electric field therapy system stored in the memory and executable on the processor (not shown). When the processor (not shown) executes the electrode patch recognition program of the electric field therapy system, the aforementioned electrode patch recognition of the electric field therapy system is realized.
[0163] According to the first adapter 200L7 of the electric field therapy system of the present disclosure, when the electrode pad 100L7 is functioning normally, the first adapter 200L7 can automatically identify the type of electrode pad 100L7, thereby enabling temperature acquisition for different types of electrode pads 100L7 without missing any data or generating interference signals. Once the type of electrode pad 100L7 is determined, it can be determined whether a temperature detection failure has occurred in the corresponding electrode pad 100L7.
[0164] The present disclosure also provides an electric field generator 300L7 for an electric field therapy system, comprising a memory (not shown), a processor (not shown), and an electrode patch recognition program for the electric field therapy system stored in the memory (not shown) and executable on the processor. When the processor (not shown) executes the electrode patch recognition program for the electric field therapy system, the aforementioned electrode patch recognition of the electric field therapy system is realized.
[0165] According to the electric field generator 300L7 of the electric field therapy system of the present disclosure, when the electrode sheet 100L7 is operating normally, the electrode sheet type can be automatically identified, thereby enabling temperature acquisition for different types of electrode sheets 100L7 without missing any data or generating any interference signals. Once the type of electrode sheet 100L7 is determined, it can be determined whether the corresponding electrode sheet 100L7 has a temperature detection failure.
[0166] Based on the above coding principles, the quality of the electrode sheet 100L7 can be monitored during use, allowing users to replace the electrode sheet 100L7 in a timely manner to avoid low-temperature burns. For example, the first controller 210L7 determines a test code array based on the sampled detection signals of each temperature detector 114L7, and compares the test code array with a preset standard code array to identify the fault condition of each temperature detector 114L7 in the electrode sheet 100L7. The standard code array includes at least the first code of the first code and the second code.
[0167] In some embodiments, the first adapter 200L7 further includes a reminder unit (not shown), which is connected to the first controller 210L7. When a faulty temperature detector 114L7 is present in the electrode sheet 100L7, the first controller 210L7 controls the reminder unit (not shown) to issue a first reminder message and instruct the electric field generator 300L7 to continue operating. For example, when the temperature detector 114L7 is not faulty in the electrode sheet 100L7, the first controller 210L7 controls the reminder unit, such as an indicator light, to light green. When a faulty temperature detector 114L7 is present in the electrode sheet 100L7, the first controller 210L7 controls the reminder unit, such as an indicator light, to light red.
[0168] The first controller 210L7 also determines the number of faulty temperature detectors 114L7 in the electrode sheet 100L7 when comparing the test code array with the preset standard code array, and determines whether the electrode sheet 100L7 needs to be replaced based on the number. For example, when the number exceeds a preset number (the minimum can be set to 1), it is determined that the electrode sheet 100L7 needs to be replaced, and when the number does not exceed the preset number, it is determined that the electrode sheet 100L7 does not need to be replaced. The first controller 210L7 can also control the reminder unit (not shown) to issue a second reminder message when it is determined that the electrode sheet 100L7 needs to be replaced, and instruct the electric field generator 300L7 to stop working. For example, when the first controller 210L7 determines that the electrode sheet 100L7 needs to be replaced, it controls the reminder unit (not shown) such as an indicator light to light red and flash, and can also control the reminder unit (not shown) such as a buzzer alarm, and at the same time send a corresponding signal to the electric field generator 300L7 through the first communication transceiver 250L7 so that the electric field generator 300L7 stops outputting the alternating electric signal.
[0169] During the process of tumor electric field therapy using electrode sheet 100L7, first adapter 200L7 periodically performs the aforementioned fault detection of electrode sheet 100L7 and replaces electrode sheet 100L7 in a timely manner. In addition to periodically performing the aforementioned fault detection of electrode sheet 100L7, first adapter 200L7 also obtains a number of AD sampling values based on the detection signals sampled from each temperature detector 114L7, and transmits the AD sampling values to first controller 210L7. First controller 210L7 converts the AD sampling values into a temperature signal to determine the temperature at the corresponding electrode element 112L7. First controller 210L7 transmits the temperature signal to electric field generator 300L7 via first communication transceiver 250L7. When electric field generator 300L7 identifies an overtemperature condition in electrode sheet 100L7 based on the temperature at the corresponding electrode element 112L7, electric field generator 300L7 reduces the amplitude of the alternating electric signal or stops outputting the alternating electric signal. In this embodiment, the first controller 210L7 can calculate the temperature of each electrode element 112L7 in the electrode sheet 100L7 based on a plurality of AD sampling values, and then compare the temperature with a preset temperature. If the temperature exceeds the preset temperature, the electrode sheet 100L7 is deemed to be overheated. In this case, a corresponding signal can be sent to the electric field generator 300L7 via the first communication transceiver 250L7, so that the electric field generator 300L7 stops outputting the alternating electrical signal or reduces the amplitude of the alternating electrical signal. The preset temperature range can be 39°C to 41°C, preferably 40.5°C.
[0170] It should be noted that the electric field generator 300L7 can also determine the test coding array based on the sampled detection signal of each temperature detector 114L7, and compare the test coding array with the preset standard coding array to identify the fault condition of each temperature detector 114L7 in the electrode sheet 100L7.
[0171] In some embodiments, the electric field generator 300L7 further issues a first reminder message and continues to output the alternating electric signal when a faulty temperature detector 114L7 is present in the electrode sheet 100L7. For example, the electric field generator 300L7 may include a reminder unit (not shown) that controls the reminder unit (not shown), such as an indicator light, to illuminate green when no faulty temperature detector 114L7 is present in the electrode sheet 100L7, and controls the reminder unit (not shown), such as an indicator light, to illuminate red when a faulty temperature detector 114L74 is present in the electrode sheet 100L7.
[0172] The electric field generator 300L7 also determines the number of faulty temperature detectors 114L7 in the electrode sheet 100L7 when comparing the test coding array with the preset standard coding array, and judges whether the electrode sheet 100L7 needs to be replaced based on the number. For example, when the number exceeds the preset number, it is judged that the electrode sheet 100L7 needs to be replaced, and when the number does not exceed the preset number, it is judged that the electrode sheet 100L7 does not need to be replaced. The electric field generator 300L7 also sends a second reminder message and stops outputting the alternating electric signal when it determines that the electrode sheet 100L7 needs to be replaced. For example, when the electric field generator 300L7 determines that the electrode sheet 100L7 needs to be replaced, it controls the reminder unit (not shown) such as the indicator light to light red and flash, and can also control the reminder unit (not shown) such as the buzzer alarm, and stops outputting the alternating electric signal.
[0173] The electric field generator 300L7 also determines the temperature at the corresponding electrode element 112L7 based on a number of AD sampling values, and when the electrode sheet 100L7 is identified as overheated based on the temperature at the corresponding electrode element 112L7, the amplitude of the alternating electric signal is reduced or the output of the alternating electric signal is stopped. For example, the electric field generator 300L7 can calculate the temperature at each electrode element 112L7 in the electrode sheet 100L7 based on a number of AD sampling values, and then compare the temperature with a preset temperature. If the temperature exceeds the preset temperature, it is considered that the electrode sheet 100L7 is overheated. At this time, the output of the alternating electric signal can be stopped or the amplitude of the alternating electric signal can be reduced. The preset temperature range can be 39°C to 41°C, preferably 40.5°C.
[0174] That is to say, the first adapter 200L7 or the electric field generator 300L7 can determine the test code array of the electrode sheet 100L7 based on the AD sampling value, and identify whether the multiple temperature detectors 114L7 in the electrode sheet 100L7 are in a fault condition according to the test code array, and execute corresponding reminder and protection strategies when a fault condition exists; it can also obtain the number of faulty temperature detectors 114L7 based on the test code array when a fault condition exists, and determine whether the electrode sheet 100L7 needs to be replaced based on the number, and execute corresponding reminder and protection strategies when the electrode sheet 100L7 needs to be replaced; it can also obtain the temperature of each electrode element 112L7 in the electrode sheet 100L7 based on the AD sampling value, and determine whether the electrode sheet 100L7 is in an over-temperature condition according to the temperature, and execute corresponding reminder and protection strategies when an over-temperature condition exists.
[0175] The following is an example to illustrate the process:
[0176] Step 1: Provide at least one pair of qualified electrode sheets 100L7 (since the electrode sheets 100L7 are medical devices, each electrode sheet 100L7 undergoes multiple tests before leaving the factory to ensure that the electrode sheets 100L7 are qualified. Therefore, the electrode sheets 100L7 provided to the user are all qualified electrode sheets 100L7). Connect the at least one pair of qualified electrode sheets 100L7 to the aforementioned first adapter 200L7, and connect the aforementioned first adapter 200L7 to the aforementioned electric field generator 300L7.
[0177] Step 2: Power on the electric field generator 300L7 to provide a DC power source VCC to the temperature detectors 114L7 in at least one pair of qualified electrode sheets 100L7 for temperature detection. The first analog-to-digital converter 220L7 in the first adapter 200L7 collects the detection signals from the temperature detectors 114L7 in at least one pair of qualified electrode sheets 100L7, obtaining a plurality of AD sampling values. The first controller 210L7 in the first adapter 200L7 then obtains at least two sets of standard code arrays A1 and A2 based on the aforementioned encoding rules. These at least two sets of standard code arrays A1 and A2 can be stored in the first adapter 200L7 and used as comparison codes.
[0178] Step 3: Turn off the power of the electric field generator 300L7 and place the at least one pair of qualified electrode sheets 100L7 on the body surface corresponding to the tumor part of the patient.
[0179] Step 4: Power on the electric field generator 300L7 to provide a DC power source VCC to the temperature detectors 114L7 in at least one pair of qualified electrode sheets 100L7 for temperature detection. Simultaneously, it provides an alternating electrical signal to the electrode elements 112L7 in the electrode sheets 100L7, thereby forming an alternating electric field between the paired electrode sheets 100L7 for tumor electric field therapy. The first analog-to-digital converter 220L7 in the first adapter 200L7 collects the detection signals from the temperature detectors 114L7 in at least one pair of qualified electrode sheets 100L7, obtaining a plurality of AD sampling values. The first controller 210L7 in the first adapter 200L7 then generates at least two test code arrays B1' and B2' based on the aforementioned encoding rules.
[0180] Step 5: The first controller 210L7 in the first adapter 200L7 compares the test code arrays B1' and B2' with the corresponding standard code arrays A1 and A2 one by one. If the test code arrays B1' and B2' are consistent with the standard code arrays A1 and A2, steps 4 and 5 are repeated. If at least one of the test code arrays B1' or B2' is inconsistent with the standard code arrays A1 and A2, step 6 is performed.
[0181] Step 6: The first adapter 200L7 confirms the number of abnormal temperature detectors 114L7 in the electrode sheet 100L7 corresponding to the inconsistent test coding array B1' and / or B2', and determines whether the number of abnormal temperature detectors 114L7 in the corresponding electrode sheet 100L7 exceeds the upper limit. If it does not exceed the upper limit, proceed to step 7; if it exceeds the upper limit, proceed to step 8.
[0182] Step 7: Continue to repeat steps 4 and 5.
[0183] Step 8: The first adapter 200L7 issues an alarm by controlling the reminder unit (not shown) inside it, and at the same time sends a corresponding signal to the electric field generator 300L7 through the first communication transceiver 250L7, so that the electric field generator 300L7 stops providing alternating electric signals to the electrode elements 112L7 in the electrode sheet 100L7, reminding the user to replace the corresponding electrode sheet 100L7.
[0184] Step nine: Turn off the power of the electric field generator 300L7, remove the electrode sheet 100L7 that needs to be replaced from the first adapter 200L7, and connect a new electrode sheet 100L7 to the first adapter 200L7.
[0185] Step 10: Power on the electric field generator 300L7 and continue to provide a DC power supply VCC to the temperature detector 114L7 in the electrode sheet 100L7 connected to the first adapter 200L7 for temperature detection. The first analog-to-digital converter 220L7 in the first adapter 200L7 collects the temperature signal detected by the temperature detector 114L7 of the replaced qualified electrode sheet 100L7 and obtains a number of AD sampling values. The first controller 210L7 in the first adapter 200L7 obtains a new standard coding array A1' or / and A2' according to the aforementioned coding rules, and compares at least one set of the new standard coding arrays A1' or / and A2' with the corresponding standard coding arrays A1 or / and A2 stored above. If the new standard coding arrays A1' or / and A2' are consistent with the standard coding arrays A1 or / and A2, the electric field generator is turned off. The device 300L7 power supply is used to configure the replaced new electrode sheet 100L7 on the body surface corresponding to the tumor part of the patient, and then steps four and five are repeated; if after comparing the new standard coding array A1' or / and A2' with the aforementioned stored standard coding arrays A1 or / and A2 one by one, there is at least one set of new standard coding arrays A1' and / or A2' that is inconsistent with the aforementioned stored and corresponding standard coding arrays A1 and / or A2, then steps nine and ten are repeated until the new standard coding arrays A1' and / or A2' of the replaced qualified electrode sheet 100L7 are consistent with the aforementioned stored and corresponding standard coding arrays A1 and / or A2.
[0186] It should be noted that in the above steps, the paired electrode sheets 100L7 may use the electrode sheets 100L7 of the same design, that is, the standard coding arrays of the paired electrode sheets 100L7 are the same, that is, the standard coding arrays A1 and A2 are the same.
[0187] The above steps 1 and 2 can be replaced by the user inputting at least two sets of standard code arrays A1 and A2. The at least two sets of standard code arrays A1 and A2 can be stored in the first adapter 200L7 and used as comparison codes.
[0188] In the above step six, the number of abnormal temperature detectors 114L7 in the corresponding electrode sheet 100L7 is determined by the number of codes that are different when the inconsistent coding array A1' and / or A2' is compared with the corresponding standard coding arrays A1 and A2. For example, when A1' is compared with A1, only the first code is different, then the number of abnormal temperature detectors 114L7 in the corresponding electrode sheet 100L7 is 1; for another example, when A1' is compared with A1, only the last two codes are different, then the number of abnormal temperature detectors 114L7 in the corresponding electrode sheet 100L7 is 2; and so on.
[0189] In step 6 above, the upper limit can be set to 1, indicating that one temperature detector 114L7 on the electrode sheet 100L7 is abnormal, and step 8 is performed to alarm and replace the electrode sheet 100L7. In other embodiments, in step 6 above, the upper limit is not limited to 1, and can also be a positive integer that is close to the ratio of the number of temperature detectors 114L7 on the electrode sheet 100L7.
[0190] In step eight above, the reminder unit (not shown) may include at least two indicator lights (not shown) corresponding to the electrode sheets 100L7, indicating the status of the corresponding electrode sheets 100L7. When the electrode sheet 100L7 does not need to be replaced, the indicator lights (not shown) are all green; when the electrode sheet 100L7 needs to be replaced, the indicator lights (not shown) corresponding to the electrode sheet 100L7 to be replaced are red. Alternatively, the indicator lights (not shown) may be permanently lit or flashing to indicate whether the electrode sheet 100L7 does not need to be replaced or needs to be replaced.
[0191] In step eight above, the reminder unit (not shown) may further include a buzzer (not shown) to indicate the status of the electrode sheet 100L7 and to simultaneously alert the user with the indicator light (not shown). When the electrode sheet 100L7 does not need to be replaced, the buzzer (not shown) does not sound an alarm; when the electrode sheet 100L7 needs to be replaced, the buzzer (not shown) sounds an alarm.
[0192] While comparing the test code array with the standard code array in steps 4, 5, and 6 above, temperature monitoring is also performed simultaneously. The steps include the following:
[0193] Step 11: The first controller 210L7 in the first adapter 200L7 calculates the temperature signal detected by the temperature detector 114L7 based on a number of AD sampling values, and determines whether the temperature signal exceeds the preset temperature. If the temperature signal detected by the temperature detector 114L7 of the electrode sheet 100L7 exceeds the preset temperature, proceed to step 12; if the temperature signals detected by the temperature detector 114L7 of the electrode sheet 100L7 are all below the preset temperature, continue to step 11.
[0194] Step 12: When the first controller 210L7 in the first adapter 200L7 detects that the temperature detected by the temperature detector 114L7 of the electrode sheet 100L7 exceeds a preset temperature, the first controller 210L7 transmits a corresponding signal via the first communication transceiver 250L7, causing the electric field generator 300L7 to reduce or shut down the alternating electric signal of the corresponding pair of electrode sheets 100L7 until the temperature detected by the temperature detector 114L7 of the corresponding electrode sheet 100L7 falls below the preset temperature. The preset temperature range may be 39°C to 41°C, preferably 40.5°C.
[0195] It should be noted that the above process is described using the first adapter 200L7 as an example of quality monitoring of the electrode sheet 100L7.

The ground terminals 114L7A of the temperature detectors 114L7 corresponding to each row group are grounded together via a first switch 240L7. By configuring the on / off states of the first switch 240L7, the analog detection signals detected by the temperature detectors 114L7 corresponding to each row group are sampled simultaneously at the corresponding temperature sampling points. The detection signal of each temperature detector 114L7 sampled when the electrode sheet 100L7 is normal is used to characterize the type of the electrode sheet 100L7, so that the type of the electrode sheet 100L7 can be automatically identified, and then the temperature collection of different types of electrode sheets 100L7 can be realized without missing collection or generating interference signals; the detection signal of each temperature detector 114L7 sampled when the electrode sheet type is determined is also used to characterize whether the electrode sheet 100L7 has a temperature detection failure, so that an abnormal temperature detector 114L7 can be identified.

For example, the test code array includes at least one of a first code, a second code, and a third code, wherein the first code is used to indicate that the temperature detector 114L7 is in a normal state, the second code is used to indicate that the temperature detector 114L7 is in an open circuit state or an unset state, and the third code is used to indicate that the temperature detector 114L7 is in a short circuit state.

For example, the first controller 210L7 or the electric field generator 300L7 determines a test code array based on the detection signals sampled from each temperature detector 114L7, and sends the test code array to a host computer (not shown). The host computer compares the test code array with a standard code array of a qualified electrode sheet 100L7 of the same type being tested to determine whether the electrode sheet 100L7 is qualified.
[0217] In some embodiments, the host computer is further connected to a display (not shown) and an alarm (not shown). When performing quality inspection, the host computer controls the display to display the test code array and standard code array of the electrode sheet 100L7 and whether the electrode sheet 100L7 is qualified, and controls the alarm to issue a reminder message when the electrode sheet 100L7 is unqualified. It should be noted that the first adapter 200L7 and / or the electric field generator 300L7, the host computer, the display, and the alarm constitute a quality inspection system for the electrode sheet.
[0218] The following is an example of an embodiment, which specifically includes the following process:

The first adapter 200L7 obtains a set of standard coding arrays A according to the aforementioned coding rules. The standard coding array A is routed by the first adapter 200L7 through the electric field generator 300L7 to the host computer, and is finally stored in the host computer and used as a standard coding array for comparison.
[0221] Step 3: Provide a tested electrode sheet 100L7' of the same batch and type as the qualified electrode sheet 100L7, connect the tested electrode sheet 100L7' to the aforementioned first adapter 200L7, and the aforementioned first adapter 200L7 obtains a set of test code arrays B according to the aforementioned coding rules.

[0224] Step 6: The display shows that the electrode sheet 100L7 ′ under test is “unqualified”, and the electrode sheet 100L7 ′ under test is placed in the defective product area. Then, steps 3 to 4 are repeated to test the next electrode sheet 100L7 ′ under test.
[0225] In step 6, while the display shows that the electrode sheet 100L7' is "unqualified", the host computer can also control the alarm to warn the operator that the electrode sheet 100L7' is "unqualified" and needs to be placed in the defective area. The alarm can be an audible alarm, a light alarm, etc.

The signal terminals 114L8B corresponding to the temperature sensors 114L8 in each column group are connected together as a temperature sampling point. The ground terminals 114L8A corresponding to the temperature sensors 114L8 in each row group are connected to the ground pin GND via the switch unit 440L8 in the second adapter 400L8 (i.e., the first switch in Figures 2 through 16). In Figure 20 , 20 electrode elements 112L8 are connected in parallel to the same conductive trace (i.e., the first AC line) of the flexible printed circuit board 120L8, transmitting the alternating electrical signal AC. The 20 temperature detectors 114L8 are divided into four row groups and five column groups. The ground terminals 114L8A of the five temperature detectors 114L8 in each row group are short-circuited via a common conductive trace (i.e., a first ground trace) on the flexible circuit board 120L8 and connected to the ground pin GND via the switch unit 440L8. The signal terminals 114L8B of the five temperature detectors 114L8 in each row group are connected in parallel via the five conductive traces (i.e., the first signal traces) on the flexible circuit board 120L8. The signal terminals 114L8B of the four temperature detectors 114L8 in each column group are short-circuited via a common conductive trace (i.e., the first signal trace) on the flexible circuit board 120L8, with the short-circuit point serving as a temperature sampling point. The ground terminals 114L8A of the four temperature detectors 114L8 in each column group are connected in parallel via the four conductive traces (i.e., the first ground traces) on the flexible circuit board 120L8.
[0252] In the example of FIG20 , flexible circuit board 120L8 and first connector 180L8 each include four first ground wires (wires 1, 2, 3, and 4) connected to ground pin GND, five first signal wires (wires 6, 7, 8, 9, and 10) transmitting analog temperature signals detected by corresponding temperature detectors 114L8, and one first AC wire (wire 11) transmitting an alternating current signal. Flexible circuit board 120L8 and first connector 180L8 each also include a communication wire (wire 5) for transmitting a communication signal (RSD) from handshake chip 116L8 provided on flexible circuit board 120L8 to second adapter 400L8. As shown in Figures 19 and 20, the first cable 130L8 is electrically connected to the flexible circuit board 120L8, and has 11 wires, which correspond one-to-one to 4 first ground wires (wire 1, wire 2, wire 3, wire 4) connected to the ground pin GND, 5 first signal lines (wire 6, wire 7, wire 8, wire 9, wire 10) transmitting analog temperature signals detected by the corresponding temperature detector 114L8, one first AC line (wire 11) transmitting alternating electrical signals, and a communication line (wire 5) transmitting communication signals from the handshake chip 116L8 to the second adapter 400L8.
[0253] The ground pin of handshake chip 116L8 is connected to a first ground wire (one of wires 1, 2, 3, and 4) and connected to ground pin GND via switch unit 440L8. The communication pin of handshake chip 116L8 is connected to second adapter 400L8 via a communication line (wire 5). As shown in FIG20 , handshake chip 116L8 is connected to wire 5 on first connector 180L8 to obtain power and enable data communication. Handshake chip 116L8 is connected to a first ground wire on first connector 180L8 to establish a controllable GND electrical connection. In this embodiment, referring to FIG20 , handshake chip 116L8 is connected to first ground wire 4 on first connector 180L8. The handshake chip 116L8 can be an energy storage element (not shown) or an external energy storage element (not shown) that stores energy when the communication line (wire No. 5) transmits a high level, and releases energy when the communication line (wire No. 5) transmits a low level, so that the handshake chip 116L8 has sufficient power and can operate normally. Optionally, the energy storage element is a capacitor. In this way, the handshake chip 116L8 only needs to use one additional wire to operate normally. The handshake chip 116L8 is suitable for handshake communication with an external device such as an electric field generator 300L8 to determine the connection status of each pair of electrode sheets 100L8, wherein after the handshake chip 116L8 completes the handshake communication with the electric field generator 300L8, the switching state of the switch unit 440L8 is configured so that the analog temperature signal detected by the corresponding temperature detector 114L8 in each row group is sampled simultaneously by the corresponding temperature sampling point. After conversion, the analog temperature signal detected by each temperature detector 114L8 can be used to characterize the type of the electrode sheet 100L8 if the electrode sheet 100L8 is qualified, and can also be used to characterize whether the electrode sheet 100L8 has a temperature abnormality.
[0254] 19 and 20 , the second adapter 400L8 includes a second controller 410L8, a second analog-to-digital converter 420L8, a filter module 490L8, a second communication transceiver 450L8, a switch unit 440L8, a resistor bank 430L8, and a third cable 470L8. The second controller 410L8, the second analog-to-digital converter 420L8, the filter module 490L8, the second communication transceiver 450L8, the switch unit 440L8, and the resistor bank 430L8 are all located within the second adapter 400L8. The third cable 470L8 and the third socket 460L8 are located on opposite sides of the second adapter 400L8.
[0255] The second controller 410L8 is electrically connected to the communication line (No. 5 wire) of the first connector 180L8 and the flexible circuit board 120L8 to perform data communication with the handshake chip 116L8. When the second controller 410L8 receives the handshake signal sent by the electric field generator 300L8, it configures the switch state of the switch unit 440L8 to power on the handshake chip 116L8, and sends the handshake signal to the handshake chip 116L8, and determines whether the handshake communication with the handshake chip 116L8 is completed according to the feedback signal of the handshake chip 116L8. After the handshake communication is completed, the switch state of the switch unit 440L8 is configured so that the second analog-to-digital converter 420L8 can simultaneously sample the temperature signal detected by the corresponding temperature detector 114L8 in each row group through the corresponding temperature sampling point to obtain a number of AD sampling values. Then, if the electrode sheet 100L8 is qualified, the type of the corresponding electrode sheet 100L8 can be identified according to the several AD sampling values. It can also be determined whether the temperature of the corresponding electrode sheet 100L8 is abnormal according to the several AD sampling values during the process of the electric field generator 300L8 transmitting the alternating electric signal to the corresponding electrode sheet 100L8. When configuring the switch state of switch unit 440L8, second controller 410L8 can control switch unit 440L8 to sequentially and individually electrically connect four first ground lines 1, 2, 3, and 4 in first connector 180L8 to ground pin GND, thereby energizing a group of temperature detectors 114L8 connected to a corresponding first ground line to perform temperature detection. When second controller 410L8 controls switch unit 440L8 to electrically connect one of the four first ground lines in first connector 180L8 to ground pin GND, second controller 410L8 also controls switch unit 440L8 to electrically disconnect the other three first ground lines in first connector 180L8 from ground pin GND.
[0256] Resistor group 430L8 comprises five high-precision voltage-dividing resistors, each connected in series to a DC power supply VCC and the first signal lines (wires 6, 7, 8, 9, and 10) of first connector 180L8, each transmitting the analog temperature signal (voltage value of temperature detector 114L8) detected by the corresponding temperature detector 114L8. This means that each temperature sampling point is connected to the DC power supply VCC via a corresponding voltage-dividing resistor. The five voltage-dividing resistors are connected in series with the corresponding temperature detector 114L8 to provide voltage division, facilitating calculation of the voltage value of the temperature detector 114L8 and conversion of the voltage value into a digital temperature signal by the second analog-to-digital converter 420L8 to obtain an analog-to-digital (A / D) sampled value. The A / D sampled value corresponds to the digital temperature. Therefore, the A / D sampled value can be partitioned by temperature range to facilitate identification of the type of the corresponding electrode sheet 100L8 and determination of whether the corresponding electrode sheet 100L8 is experiencing a temperature anomaly. If the AD sampling value obviously deviates from the detection temperature range, for example, below 0°C or above 50°C, it is determined that the sampling point corresponding to the AD sampling value is not equipped with a temperature detector 114L8 and an electrode element 112L8, thereby determining the number of electrode elements 112L8 to identify the type of electrode sheet 100L8.
[0257] Filter module 490L8 is positioned between the second analog-to-digital converter 420L8 and the corresponding temperature sampling point. It is used to filter the temperature signal detected by each temperature detector 114L8. Filter module 490L8 includes five filter groups, each corresponding to the resistor group 430L8. These groups are designed to attenuate signals above a set cutoff frequency. The first filter group is serially connected to ports 1 and 6 of filter module 490L8; the second filter group is serially connected to ports 2 and 7 of filter module 490L8; the third filter group is serially connected to ports 3 and 8 of filter module 490L8; the fourth filter group is serially connected to ports 4 and 9 of filter module 490L8; and the fifth filter group is serially connected to ports 5 and 10 of filter module 490L8. Optionally, the filter utilizes a first-order RC low-pass filter with a cutoff frequency less than 1 / 10 of the AC frequency of the alternating electrical signal. Optionally, a voltage follower may be incorporated into filter module 490L8 to optimize sampling by the second analog-to-digital converter 420L8.
[0258] The second analog-to-digital converter 420L8 has five detection channels: A, B, C, D, and E. The five detection channels of the second analog-to-digital converter 420L8 are electrically connected to a corresponding set of filters of the filter module 490L8. Specifically, the five detection channels of the second analog-to-digital converter 420L8 are connected in a one-to-one correspondence with ports 6, 7, 8, 9, and 10 of the filter module 490L8, thereby electrically connecting the corresponding set of filters. The second analog-to-digital converter 420L8 can convert the multiple analog temperature signals filtered by the filter module 490L8 into multiple digital temperature signals to obtain multiple analog-to-digital (A / D) sample values. The multiple A / D sample values converted by the second analog-to-digital converter 420L8 are serially transmitted to the third adapter 500L8 by the second communication transceiver 450L8 under the control of the second controller 410L8.
[0259] The second adapter 400L8 exchanges data with the third adapter 500L8 via the second communication transceiver 450L8. The second communication transceiver 450L8 enables the second controller 410L8 to exchange data with the third adapter 500L8. Optionally, the second communication transceiver 450L8 uses a UART unit.
[0260] Referring to Figure 20 , the third cable 470L8 of the second adapter 400L8 includes five conductors. These five conductors transmit alternating current signals (AC), ground (GND), voltage (VCC), and bidirectional serial data transmission. The GND and VCC terminals within the second adapter 400L8 are connected.
[0261] 19 and 21 , the third adapter 500L8 includes a third communication transceiver 520L8, a third controller 510L8, a fourth communication transceiver 530L8, and a fourth cable 560L8. The third communication transceiver 520L8, the third controller 510L8, and the fourth communication transceiver 530L8 are all located inside the third adapter 500L8.
[0262] The third adapter 500L8 is electrically connected to each of the four second adapters 400L8 via a corresponding third connector 480L8. Each third connector 480L8 is adapted to connect a corresponding second adapter 400L8 to the third adapter 500L8. The third connector 480L8 transmits signals transmitted by the third cable 470L8, namely, alternating electrical signals AC, GND, VCC, and bidirectional serial data. The third connector 480L8 is a third plug. The third adapter 500L8 is also equipped with a plurality of corresponding fourth sockets 550L8. These third plugs and fourth sockets 550L8 are plug-in connectors, meaning that the third connector 480L8 is configured to connect the second adapter 400L8 to the third adapter 500L8 using a plug-in connector. The fourth cable 560L8 and the plurality of fourth sockets 550L8 are located on opposite sides of the third adapter 500L8. The third adapter 500L8 is equipped with four fourth sockets 550L8, which are connected one-to-one to the four second adapters 400L8 connected to the four electrode sheets 100L8. Each fourth socket 550L8 has five connection terminals that transmit the signals transmitted by the third cable 470L8: alternating current signal AC, GND, VCC, and bidirectional serial transmission data.
[0263] Each of the four fourth sockets 550L8 has a connection terminal for an alternating electrical signal AC, each connected to one of the four alternating electrical signals (X1, X2, Y1, Y2). Each of the four fourth sockets 550L8 transmits one of the four alternating electrical signals (X1, X2, Y1, Y2) and is electrically connected to the electrode pads 100L8-X1, 100L8-X2, 100L8-Y1, and 100L8-Y2 via a corresponding second adapter 400L8. Among them, the fourth socket 550L8 for transmitting the alternating electrical signal X1 is electrically connected to the third connector 480L8 of a corresponding second adapter 400L8 connected to the electrode sheet 100L8-X1; the fourth socket 550L8 for transmitting the alternating electrical signal X2 is electrically connected to the third connector 480L8 of a corresponding second adapter 400L8 connected to the electrode sheet 100L8-X2; the fourth socket 550L8 for transmitting the alternating electrical signal Y1 is electrically connected to the third connector 480L8 of a corresponding second adapter 400L8 connected to the electrode sheet 100L8-Y1; the fourth socket 550L8 for transmitting the alternating electrical signal Y2 is electrically connected to the third connector 480L8 of a corresponding second adapter 400L8 connected to the electrode sheet 100L8-Y2.
[0264] Third adapter 500L8 is electrically connected to electric field generator 300L8 via fourth connector 540L8. Fourth connector 540L8 is adapted to connect electric field generator 300L8 to third adapter 500L8, allowing GND and VCC signals of electric field generator 300L8, as well as the alternating electrical signals X1, X2, Y1, and Y2 generated thereby, to be transmitted to third adapter 500L8 via fourth connector 540L8. Fourth connector 540L8 is a fourth plug. Meanwhile, electric field generator 300L8 is provided with a second socket 310L8. Both the fourth plug and the second socket 310L8 are connectors. In other words, fourth connector 540L8 is configured to connect third adapter 500L8 to electric field generator 300L8 using a connector configuration.
[0265] The third communication transceiver 520L8 is connected between the four third connectors 480L8 and the third controller 510L8. The third controller 510L8 exchanges data with the second communication transceivers 450L8 of the four second adapters 400L8 via the third communication transceiver 520L8. Optionally, the third communication transceiver 520L8 utilizes a UART unit. The second controller 410L8 can transmit feedback signals from the corresponding handshake chip 116L8 to the third controller 510L8, so that the third controller 510L8 can determine whether the corresponding second controller 410L8 and the handshake chip 116L8 have completed handshake communication based on the feedback signals from the handshake chip 116L8. The second controller 410L8 can also send a number of AD sampling values to the third controller 510L8, so that when the electrode sheet 100L8 is qualified, the third controller 510L8 can identify the type of the corresponding electrode sheet 100L8 based on the number of AD sampling values, and / or, in the process of the electric field generator 300L8 transmitting the alternating electric signal to the corresponding electrode sheet 100L8, determine whether the temperature of the corresponding electrode sheet 100L8 is abnormal based on the number of AD sampling values.
[0266] The third controller 510L8 is generally connected between the third communication transceiver 520L8 and the fourth communication transceiver 530L8. The fourth communication transceiver 530L8 is generally electrically connected to the electric field generator 300L8 via the fourth connector 540L8. The third controller 510L8 exchanges data with the electric field generator 300L8 via the fourth communication transceiver 530L8. Optionally, the fourth communication transceiver 530L8 is an RS485-UART transceiver. The alternating electrical signal within the third adapter 500L8 corresponds one-to-one with a connection terminal (X1, X2, Y1, or Y2) of the fourth socket 550L8 that transmits the alternating electrical signal. The second controller 410L8 can transmit the feedback signal from the handshake chip 116L8 to the electric field generator 300L8 via the third adapter 500L8, so that the electric field generator 300L8 can determine whether the second controller 410L8 and the handshake chip 116L8 have completed handshake communication based on the feedback signal from the handshake chip 116L8. The second controller 410L8 can also transmit a plurality of AD sampling values to the electric field generator 300L8 via the third adapter 500L8, so that if the electrode sheet 100L8 is qualified, the electric field generator 300L8 can identify the type of the corresponding electrode sheet 100L8 based on the plurality of AD sampling values, and / or, when transmitting the alternating electrical signal to the corresponding electrode sheet 100L8, determine whether the corresponding electrode sheet 100L8 has a temperature abnormality based on the plurality of AD sampling values.
[0267] As can be seen from the foregoing description, the determination of handshake communication, the identification of the type of electrode sheet 100L8, and the identification of whether the temperature of the electrode sheet 100L8 is abnormal can be implemented by the second controller 410L8 in the second adapter 400L8, the third controller 510L8 in the third adapter 500L8, or the electric field generator 300L8, and the specific details are not limited here. It should be noted that the number of electrode sheets 100L8, the number of electrode elements 112L8 in each electrode sheet 100L8, the number of temperature detectors 114L8 provided, etc., are all exemplary descriptions and are not intended to limit the present disclosure.
[0268] In the above embodiment, the plurality of electrode elements 112L8 are configured as a plurality of row groups and a plurality of column groups in terms of circuit connection, and the signal terminals 114L8B of the temperature detectors 114L8 corresponding to the temperature detectors 114L8 in each column group are connected together as temperature sampling points, the ground terminals 114L8A of the temperature detectors 114L8 corresponding to the temperature detectors 114L8 in each row group are connected to the ground pin GND through the switch unit 440L8, and the handshake communication is performed with the electric field generator 300L8 through the handshake chip 116L8 to determine the connection status of the electrode sheet 100L8, wherein the handshake chip 116L8 and the electric field generator are connected together. After 300L8 completes the handshake communication, the switching state of the switch unit 440L8 is configured so that the analog temperature signal detected by the corresponding temperature detector 114L8 in each row group is sampled simultaneously by the corresponding temperature sampling point. In this way, the coverage rate of the temperature sensor can be effectively increased while controlling the number of cable cores, thereby avoiding excessive weight on the electrode sheet 100L8 and maintaining the application effect of the electrode sheet 100L8; at the same time, based on the AD sampling value obtained by the sampling analog-to-digital conversion, the type of the electrode sheet 100L8 and whether the electrode sheet 100L8 has a temperature abnormality can be identified.
[0269] The present disclosure also provides a temperature detection method for an electric field therapy system, as shown in FIG22 , the method includes:
[0270] In step S401, a handshake communication is performed with the handshake chip 116L8 via an adapter unit (not numbered) to determine the connection status of the corresponding electrode sheet 100L8.
[0271] In step S402, when each electrode sheet 100L8 is successfully connected to the adapter unit, the switch state of the switch unit 440L8 is configured through the adapter unit so that the temperature signal detected by the corresponding temperature detector 114L8 in each row group is sampled simultaneously through the corresponding temperature sampling point.
[0272] Optionally, the method further includes: identifying the type of the corresponding electrode sheet 100L8 based on the sampled temperature signal detected by each temperature detector 114L8. For example, performing analog-to-digital conversion based on the sampled analog temperature signal detected by each temperature detector 114L8 to obtain a plurality of AD sampling values; determining the number of electrode elements 112L8 of the corresponding electrode sheet 100L8 based on the plurality of AD sampling values, and determining the type of the corresponding electrode sheet 100L8 based on the number of electrode elements 112L8.
[0273] Optionally, during the process of the electric field generator 300L8 transmitting the alternating electric signal to the corresponding electrode sheet 100L8, the method further includes: judging whether the temperature of the corresponding electrode sheet 100L8 is abnormal according to a plurality of AD sampling values.
[0274] Optionally, during the process of the electric field generator 300L8 transmitting the alternating electric signal to the corresponding electrode sheet 100L8, the method further includes: adjusting parameters of the alternating electric signal according to a plurality of AD sampling values.
[0275] For example, the handshake, temperature detection, and electric field control process of an electric field therapy system is shown in Figure 23. This process can be applied to the electric field therapy system shown in Figure 19 to perform tumor electric field therapy. This process is not limited to the example shown in Figure 19 and also applies to the examples shown in Figures 25 and 26. The following steps are based on the example shown in Figure 19.
[0276] In S501, the electric field therapy system is connected. Specifically, four C-shaped electrode sheets 100L8 are connected to corresponding second adapters 400L8, four second adapters 400L8 are connected to a third adapter 500L8, the third adapter 500L8 is connected to the electric field generator 300L8, and the electric field generator 300L8 is connected to an appropriate power source.
[0277] In S502, it is detected whether the user issues a command to turn on the electric field. If no command to turn on the electric field is detected, S502 is repeated; if a command to turn on the electric field is detected, the process proceeds to S503.
[0278] In S503, after the electric field generator 300L8 of the electric field therapy system sends a handshake signal to the X1 port (third connector 480L8-X1, second adapter 400L8) via the third adapter 500L8, the second controller 410L8 of the second adapter 400L8, connected to the third connector 480L8-X1, receives the data transmitted by the corresponding wire No. 5 on the first connector 180L8 and determines whether the handshake succeeded. If it fails, the process proceeds to S504; if it succeeds, the process proceeds to S505. This determination step can occur in the second adapter 400L8, the third adapter 500L8, or the electric field generator 300L8. In this embodiment, the determination step occurs in the second adapter 400L8. Specifically, when the electrode sheet 100L8-X1 is connected normally, the handshake chip 116L8 can receive the handshake request signal from the electric field generator 300L8 and feedback the handshake status to the second controller 410L8 of the second adapter 400L8. The second controller 410L8 of the second adapter 400L8 determines that the handshake is successful. Conversely, when the electrode sheet 100L8-X1 is connected abnormally, the second controller 410L8 of the second adapter 400L8 cannot receive the feedback signal from the handshake chip 116L8. The second controller 410L8 of the second adapter 400L8 determines that the handshake has failed.
[0279] In S504, the electric field therapy system issues an alarm due to handshake failure and then enters step S502.
[0280] In S505, after the electric field generator 300L8 of the electric field therapy system sends a handshake signal to the X2 port (third connector 480L8-X2, second adapter 400L8) via the third adapter 500L8, the second controller 410L8 of the second adapter 400L8, connected to the third connector 480L8-X2, receives the data transmitted by the corresponding wire No. 5 on the first connector 180L8 to determine whether the handshake succeeded. If not, the process proceeds to S502; if successful, the process proceeds to S506. This determination step can occur in the second adapter 400L8, the third adapter 500L8, or the electric field generator 300L8. In this embodiment, the determination step occurs in the second adapter 400L8. Specifically, when the electrode sheet 100L8-X2 is connected normally, the handshake chip 116L8 can receive the handshake request signal from the electric field generator 300L8 and feedback the handshake status to the second controller 410L8 of the second adapter 400L8. The second controller 410L8 of the second adapter 400L8 determines that the handshake is successful. Conversely, when the electrode sheet 100L8-X2 is connected abnormally, the second controller 410L8 of the second adapter 400L8 cannot receive the feedback signal from the handshake chip 116L8. The second controller 410L8 of the second adapter 400L8 determines that the handshake has failed.
[0281] In S506, after the electric field generator 300L8 of the electric field therapy system sends a handshake signal to the Y1 port (third connector 480L8-Y1, second adapter 400L8) via the third adapter 500L8, the second controller 410L8 of the second adapter 400L8, connected to the third connector 480L8-Y1, receives the data transmitted by the corresponding wire No. 5 on the first connector 180L8 and determines whether the handshake succeeded. If not, the process proceeds to S502; if successful, the process proceeds to S507. This determination step can occur in the second adapter 400L8, the third adapter 500L8, or the electric field generator 300L8. In this embodiment, the determination step occurs in the second adapter 400L8. Specifically, when the electrode sheet 100L8-Y1 is connected properly, the handshake chip 116L8 can receive the handshake request signal from the electric field generator 300L8 and feedback the handshake status to the second controller 410L8 of the second adapter 400L8. The second controller 410L8 of the second adapter 400L8 determines that the handshake is successful. Conversely, when the electrode sheet 100L8-Y1 is connected abnormally, the second controller 410L8 of the second adapter 400L8 cannot receive the feedback signal from the handshake chip 116L8. The second controller 410L8 of the second adapter 400L8 determines that the handshake has failed.
[0282] In S507, after the electric field generator 300L8 of the electric field therapy system sends a handshake signal to the Y2 port (third connector 480L8-Y2, second adapter 400L8) via the third adapter 500L8, the second controller 410L8 of the second adapter 400L8, connected to the third connector 480L8-Y2, receives the data transmitted by the corresponding wire No. 5 on the first connector 180L8 to determine whether the handshake passed. If not, the process proceeds to S502; if passed, the process proceeds to S508. This determination step can occur in the second adapter 400L8, the third adapter 500L8, or the electric field generator 300L8. In this embodiment, the determination step occurs in the second adapter 400L8. Specifically, when the electrode sheet 100L8-Y2 is connected normally, the handshake chip 116L8 can receive the handshake request signal from the electric field generator 300L8 and feedback the handshake status to the second controller 410L8 of the second adapter 400L8. The second controller 410L8 of the second adapter 400L8 determines that the handshake is successful. Conversely, when the electrode sheet 100L8-Y2 is connected abnormally, the second controller 410L8 of the second adapter 400L8 cannot receive the feedback signal from the handshake chip 116L8. The second controller 410L8 of the second adapter 400L8 determines that the handshake has failed.
[0283] In the above S503, S505, S506, and S507, after receiving the handshake signal from the electric field therapy system, the second adapter 400L8 needs to control the switch unit 440L8 through the second controller 410L8 to electrically connect the No. 4 wire on the first connector 180L8 to the ground pin GND, so that the handshake chip 116L8 can operate normally. If the connections between the electric field generator 300L8 and the third adapter 500L8, between the third adapter 500L8 and the second adapter 400L8, and between the second adapter 400L8 and the electrode sheet 100L8 are all normal, the handshake signal emitted by the electric field generator 300L8 will ultimately reach the handshake chip 116L8 of the electrode sheet 100L8, and the handshake status of the handshake chip 116L8 can be fed back to the electric field generator 300L8. If at least one connection abnormality occurs between the electric field generator 300L8 and the third adapter 500L8, between the third adapter 500L8 and the second adapter 400L8, or between the second adapter 400L8 and the electrode sheet 100L8, the handshake chip 116L8 cannot connect VCC and GND to form a loop, resulting in the second adapter 400L8, the third adapter 500L8, and the electric field generator 300L8 receiving the handshake status empty signal, and the handshake fails.
[0284] In S508, the electric field generator 300L8 of the electric field therapy system sets the electric field parameters and then proceeds to S509. The electric field parameters include the frequency and amplitude of the alternating electric signal.
[0285] In S509, the third adapter 500L8 sends a temperature reading request to the two second adapters 400L8 corresponding to the third connectors 480L8-Y1 and 480L8-Y2. The third adapter 500L8 then reads the temperature signals to collect the temperatures corresponding to the 40 temperature sensors 114L8 on the electrode sheets 100L8-Y1 and 100L8-Y2. The process then proceeds to S510.
[0286] In S510, the electric field therapy system determines the type of electrode sheets 100L8-Y1 and 100L8-Y2 based on the temperature signals and then proceeds to S511. The type of 100L8-Y1 and 100L8-Y2 is determined by determining the number of electrode elements 112L8 and temperature detectors 114L8 in the electrode sheets 100L8-Y1 and 100L8-Y2. This determination process can occur in the second adapter 400L8, the third adapter 500L8, or the electric field generator 300L8. In the example shown in FIG19, both 100L8-Y1 and 100L8-Y2 are determined to be C-type electrode sheets 100L8. The C-type electrode sheet 100L8 has 20 temperature detectors 114L8, so the C-type electrode sheet 100L8 contains 20 valid temperature signals, and 100L8-Y1 and 100L8-Y2 have a total of 40 valid temperature signals.
[0287] In S511, the electric field therapy system determines whether any one of the 40 valid temperature signals collected by the second adapter 400L8 is abnormal, and if so, proceeds to S513. If all 40 valid temperature signals are normal, proceeds to S512.
[0288] In S512 , the electric field generator 300L8 turns on the alternating electric signals Y1 and Y2 , turns off the alternating electric signals X1 and X2 and enters S514 .
[0289] In S513, the electric field therapy system alarms due to abnormal effective temperature signals of electrode sheets 100L8-Y1 and 100LY-Y2, and then immediately enters S519.
[0290] In S514, the third adapter 500L8 sends a temperature reading request to the two second adapters 400L8 corresponding to the third connectors 480L8-X1 and 480L8-X2. The third adapter 500L8 then reads the temperature signals to collect the temperatures corresponding to all temperature detectors 114L8 on the electrode sheets 100L8-X1 and 100L8-X2. The process then proceeds to S515.
[0291] The above steps S509 and S514 are consistent with those of the second adapter 400L8. For the specific processes of S509 and S514 in the second adapter 400L8, please refer to the process shown in FIG. 24 .
[0292] In S515, the electric field therapy system determines the type of electrode sheets 100L8-X1 and 100L8-X2 based on the temperature signals and then proceeds to S516. This determination process can occur in the second adapter 400L8, the third adapter 500L8, or the electric field generator 300L8. In the example shown in FIG19 , both 100L8-X1 and 100L8-X2 are determined to be C-type electrode sheets 100L8. The C-type electrode sheet 100L8 has 20 temperature detectors 114L8, so the C-type electrode sheet 100L8 contains 20 valid temperature signals, for a total of 40 valid temperature signals from 100L8-X1 and 100L8-X2.
[0293] In S516, the electric field therapy system determines whether any one of the 40 valid temperature signals collected by the second adapter 400L8 is abnormal. If so, the process proceeds to S513. If all 40 valid temperature signals are normal, the process proceeds to S517.
[0294] In S517, the electric field generator 300L8 turns on the alternating electric signals X1 and X2, turns off the alternating electric signals Y1 and Y2, and enters S518. The total time of S512, S514, S515, S516 to S517 is fixed, and the total time is 1 second.
[0295] In S518, the electric field therapy system detects whether it has received a command from the user to turn off the electric field. If it is detected that a command to turn off the electric field has been received, it enters S519; if it is not detected that a command to turn off the electric field has been received, it enters S520.
[0296] In S519, the electric field therapy system turns off the electric field and then enters S502. At this point, the electric field therapy ends and waits for the next electric field turn-on command.
[0297] In S520, the electric field therapy system determines whether the electric field parameters need to be adjusted based on the current electric field amplitude and the collected temperature signal. If adjustment is required, the system proceeds to S508; if not, the system proceeds to S509 through S518 and loops. The total duration of S517, S518, S520, S509, S510, S511, and S512 is fixed, and in this embodiment is 1 second. This allows the electric field therapy system to continuously output alternating electric signals in the X1 and X2 directions, alternating with alternating electric signals in the Y1 and Y2 directions, with a 2-second cycle. Simultaneously, the electric field therapy system can reduce the time interval between turning off the alternating electric signals X1 and X2 and turning on the alternating electric signals Y1 and Y2 to 0 seconds, and also reduce the time interval between turning off the alternating electric signals Y1 and Y2 and turning on the alternating electric signals X1 and X2 to 0 seconds, thereby improving the efficiency of electric field therapy while ensuring the accuracy of temperature acquisition.
[0298] The temperature collection process is shown in Figure 24. This process can be applied to the temperature collection process of the second adapter 400L8 of any applicable electrode sheet 100L8-X1, 100L8-X2, 100L8-Y1, 100L8-Y2. The above flowchart takes the second adapter 400L8 connected to 100L8-X1 as an example.
[0299] In S601, the second adapter 400L8 is connected to the electrode sheet 100L8-X1 and the third adapter 500L8. Then, the process proceeds to S602.
[0300] In S602, the second adapter 400L8 determines whether it has received the temperature reading request sent by the third adapter 500L8. If it has received the temperature reading request, it proceeds to S603; if it has not received the temperature reading request, it repeats S602.
[0301] In S603, the second controller 410L8 of the second adapter 400L8 controls the switch unit 440L8 to electrically connect wire 1 of the first connector 180L8 to GND in the second adapter 400L8, while disconnecting wires 2, 3, and 4 (wires 2, 3, and 4 are disconnected from GND). At this point, the five temperature sensors 114L8 numbered 1-5 on the electrode sheet 100L8-X1 are electrically connected to the resistor group 430L8 and GND, while the 15 temperature sensors 114L8 numbered 6-20 are not electrically connected.
[0302] In S604, the second analog-to-digital converter 420L8 acquires the temperature signals corresponding to the temperature detectors 114L8 numbered 1-5 on the filtered electrode sheet 100L8-X1. The second analog-to-digital converter 420L8 acquires the analog temperature signals detected by the five temperature detectors 114L8 numbered 1-5 on the filtered electrode sheet 100L8-X1 in the order of detection channels AE and converts them into digital temperature signals, then proceeds to S605. During the temperature acquisition period, the alternating electrical signal emitted by the electric field generator 300L8 is electrically connected to Y1 and Y2. In this embodiment, the voltage amplitude between Y1 and Y2 is typically greater than 100 Vpp. At this point, the alternating electrical signal emitted by the electric field generator 300L8 is electrically disconnected from X1 and X2. However, because the device controlling the switching of the alternating electrical signal typically has certain parasitic parameters, when the alternating electrical signal is applied and X1 and X2 are disconnected, X1 and X2 still have a certain voltage amplitude. In the example shown in FIG19 , the voltage amplitude of X1 and Y1 is typically greater than 4 Vpp. At this time, the residual alternating electrical signal between X1 and X2 will be coupled to the various modules and conductive traces inside the second adapter 400L8, affecting the temperature collection of the second adapter 400L8 and generating certain errors. Therefore, the filtering module 490L8 is required to attenuate the medium and high frequency signals in the analog temperature signal detected by the corresponding temperature detector 114L8 and then provide the second analog-to-digital converter 420L8 with the conversion into a more accurate digital temperature signal.
[0303] In S605, the second controller 410L8 of the second adapter 400L8 controls the switch unit 440L8 to electrically connect wire 2 of the first connector 180L8 to the GND in the second adapter 400L8, while wires 1, 3, and 4 are disconnected (wires 1, 3, and 4 are disconnected from GND). At this point, the five temperature sensors 114L8 numbered 6-10 on the electrode sheet 100L8-X1 are electrically connected to the resistor group 430L8 and GND, while the 15 temperature sensors 114L8 numbered 1-5 and coded 11-20 are not electrically connected. The process proceeds to S606.
[0304] In S606, the second analog-to-digital converter 420L8 acquires the temperature signals corresponding to the temperature detectors 114L8 numbered 6-10 on the electrode sheet 100L8-X1 after filtering. The second analog-to-digital converter 420L8 acquires the analog temperature signals detected by the five temperature detectors 114L8 numbered 6-10 on the electrode sheet 100L8-X1 after filtering in the order of detection channels AE and converts them into digital temperature signals, then proceeds to S607.
[0305] In S607, the second controller 410L8 of the second adapter 400L8 controls the switch unit 440L8 to electrically connect wire 3 of the first connector 180L8 to the GND in the second adapter 400L8, while wires 1, 2, and 4 are disconnected (wires 1, 2, and 4 are disconnected from GND). At this point, the five temperature sensors 114L8 numbered 11-15 on the electrode sheet 100L8-X1 are electrically connected to the resistor group 430L8 and GND, while the fifteen temperature sensors 114L8 numbered 1-10 and 16-20 are not electrically connected. The process proceeds to S608.
[0306] In S608, the second analog-to-digital converter 420L8 acquires the temperature signals corresponding to the temperature detectors 114L8 numbered 11-15 on the electrode sheet 100L8-X1 after filtering. The second analog-to-digital converter 420L8 acquires the analog temperature signals detected by the five temperature detectors 114L8 numbered 11-15 on the electrode sheet 100L8-X1 after filtering in the order of detection channels AE and converts them into digital temperature signals, then proceeds to S609.
[0307] In S609, second controller 410L8 of second adapter 400L8 controls switch unit 440L8, electrically connecting wire 4 in first connector 180L8 to GND in second adapter 400L8 and disconnecting wires 1, 2, and 3 (wires 1, 2, and 3 are disconnected from GND). At this point, the five temperature sensors 114L8 numbered 16-20 on electrode sheet 100L8-X1 are electrically connected to resistor group 430L8 and GND, while the 15 temperature sensors 114L8 numbered 1-15 are not electrically connected. The process proceeds to S610.
[0308] At S610, the second analog-to-digital converter 420L8 acquires the temperature signals corresponding to the temperature detectors 114L8 coded 16-20 on the filtered electrode sheet 100L8-X1. The second analog-to-digital converter 420L8 acquires the analog temperature signals detected by the five temperature detectors 114L8 coded 16-20 on the filtered electrode sheet 100L8-X1 in the order of detection channels AE and converts them into digital temperature signals, then proceeds to S611.
[0309] In step S611, the second adapter 400L8 completes temperature acquisition, and the second controller 410L8 transmits a temperature signal to the third adapter 500L8 via the second communication transceiver 450L8, and then proceeds to step S602. The temperature signal in this step is a digital temperature signal converted by the second analog-to-digital converter 420L8. Optionally, the transmitted temperature signal may include information about the type of the electrode sheet 100L8-X1.
[0310] In some embodiments, as shown in FIG. 25 , the electrode sheet 100L9 is a B-type electrode sheet 100L9 having 13 electrode elements 112L9 ; as shown in FIG. 26 , the electrode sheet 100L10 is an A-type electrode sheet 100L10 having 9 electrode elements 112L10 .
[0311] It should be noted that in the example of Figure 19, the electrode sheets 100L8-X1, 100L8-X2, 100L8-Y1, and 100L8-Y2 can be used in any combination of type A, type B, and type C. For example, 100L8X1 and 100L8-X2 use type B electrode sheet 100L9, and 100L8-Y1 and 100L8-Y2 use type C electrode sheet 100L10.
[0312] The temperature acquisition process for the B-type electrode sheet 100L9 in this embodiment is consistent with the process for the C-type electrode sheet 100L8 shown in Figure 19. However, in S608 of the temperature acquisition process, the analog temperature signals acquired by detection channels D and E of the second analog-to-digital converter 420L9 are close to the analog signal of the VCC power supply voltage value. This is because wires 4, 5, 9, and 10 on the electrode sheet 100L9, which are electrically connected to detection channels D and E, are not electrically connected to GND. Similarly, in S610 of the temperature acquisition process, the analog temperature signals acquired by detection channels AE of the second analog-to-digital converter 420L9 are close to the analog signal of the VCC power supply voltage value. This is because wires 1-13 on the electrode sheet 100L9, which are electrically connected to detection channels AE, are not electrically connected to GND. Therefore, in S611, the temperature signal transmitted by the second adapter 400L9 includes the digital temperature signals corresponding to 13 temperature sensors 114L9 on the electrode sheet 100L9 (numbers 1-13), and the digital temperature signals corresponding to 7 temperature sensors 14-20 (numbers 14-20) that are not equipped with temperature sensors 114L9, which are converted from analog signals close to the VCC supply voltage. These 7 digital temperature signals converted from analog signals close to the VCC supply voltage are the interference temperature data.
[0313] The electric field therapy system process for the B-type electrode sheet 100L9 in this embodiment is consistent with the process for the C-type electrode sheet 100L8 shown in Figure 19. Taking the B-type electrode sheet 100L9-X1 as an example, the analog temperature signals corresponding to the seven temperature signals numbered 14-20 without temperature detectors 114L9 in S515 are all analog signals close to the VCC power supply voltage value. The third adapter 500L9 can determine that 100L9-X1 is a B-type electrode sheet based on the above basis. Optionally, the judgment process can occur in the second adapter 400L9. When processing the temperature signal, the electric field therapy system can exclude the temperature signals corresponding to the seven temperature signals numbered 14-20 without temperature detectors 114L9 before performing data processing. For example, for a system in which electrode pieces 100L8-X1 and 100L8-X2 use B-type electrode piece 100L9, and electrode pieces 100L8Y1 and 100L8-Y2 use C-type electrode piece 100L10, the electric field therapy system can determine in S510 that electrode pieces 100L8-Y1 and 100L8-Y2 are both C-type electrode pieces 100L10, and that all 40 temperature signals are valid temperature data, and determine in S511 whether there are any abnormalities in the 40 valid temperature data. Normal; in S515, it is determined that the electrode sheets 100L8-X1 and 100L8-X2 are both type B electrode sheets 100L9, so the temperature signals of the 13 temperature detectors 114L9 numbered 1-13 corresponding to the electrode sheets 100L8-X1 and 100L8-X2 are valid temperature data, and the electrode sheets 100L8-X1 and 100L8-X2 have a total of 26 valid temperature data. Then, in S516, it is determined whether there is any abnormality with these 26 valid temperature data.
[0314] The temperature acquisition process for the A-type electrode sheet 100L10 in this embodiment is consistent with the process for the C-type electrode sheet 100L8 shown in Figure 19 . However, in S606, the analog temperature signal acquired by detection channel E of the second analog-to-digital converter 420L10 is close to the analog signal of the VCC power supply voltage value. This is because wire No. 10 on the electrode sheet 100L10, which is electrically connected to sampling channel 5, is not electrically connected to GND. Similarly, in S608, the analog temperature signals acquired by detection channels AE of the second analog-to-digital converter 420L10 are all close to the analog signal of the VCC power supply voltage value. This is because wires No. 3, 6, 7, 8, 9, and 10 on the electrode sheet 100L10, which are electrically connected to detection channels AE, are not electrically connected to GND. In S610, the analog temperature signals collected by detection channels AE of second analog-to-digital converter 420L10 are all analog signals close to the VCC supply voltage value. This is because wires 6, 7, 8, 9, and 10 on electrode sheet 100L10, which are electrically connected to detection channels AE, are not electrically connected to GND. Therefore, in S611, the temperature signal transmitted by second adapter 400L10 includes the digital temperature signals corresponding to the nine temperature sensors 114L10 numbered 1-9 on electrode sheet 100L10, as well as the digital temperature signals corresponding to the eleven unused temperature sensors 114L10 numbered 10-20, converted from analog signals close to the VCC supply voltage value.
[0315] The electric field therapy system process for the A-type electrode sheet 100L10 in this embodiment is consistent with the process for the C-type electrode sheet 100L8 shown in Figure 19. Taking the A-type electrode sheet 100L10-X1 as an example, the analog temperature signals corresponding to the 11 temperature sensors 114L10 numbered 10-20 in the temperature signal in S515 that are not equipped are all analog signals close to the VCC power supply voltage value. The third adapter 500L10 can determine that 100L10-X1 is an A-type electrode sheet based on the above basis. Optionally, the judgment process can occur in the second adapter 400L10. When processing the signal, the electric field therapy system can exclude the temperature signals corresponding to the temperature sensors 10-20 before performing signal processing. For example, for a system in which 100L8-X1 and 100L8-X2 use type A electrode 100L10, and 100L8-Y1 and 100L8-Y2 use type C electrode 100L8, the electric field therapy system can determine in S510 that 100L8-Y1 and 100L8-Y2 are both type C electrode 100L8, and the 40 temperature signals are all valid temperature data, and determine whether there is an abnormality in the 40 valid temperature data in S511; in S515, it can determine that 100L8-X1 and 100L8-X2 are both type A electrode 100L10, so the temperature signals of channels numbered 1-9 corresponding to 100L8-X1 and 100L8-X2 are valid temperature data, a total of 18 valid temperature data, and then determine whether there is an abnormality in these 18 valid temperature data in S516.
[0316] In this way, type A, type B, and type C electrode sheets 100L8 to 110L10 can be used in combination without changing the electric field generator, the third adapter, the second adapter, and the electric field therapy system process, and the efficiency of electric field therapy can be improved without affecting the flexibility of the electrode cable.
[0317] In the above embodiment, by adopting matrix network temperature detection technology and cooperating with the corresponding electric field control algorithm, temperature detection and electric field control can not only effectively increase the coverage of the temperature detector while controlling the number of cable cores, avoid excessive weight on the electrode sheet, and maintain the application effect of the electrode sheet, but also has the advantages of flexible electrode sheet combination, accurate electrode sheet identification, and small electric field shutdown interval, which can improve patient compliance and improve patient treatment effect; at the same time, whether the corresponding pair of electrode sheets turns off the electric field or adjusts the electric field parameters can be controlled based on the detected temperature.
[0318] The present disclosure also provides a tumor treatment device, comprising: at least one pair of the aforementioned electrode sheets such as 100L8 to 100L10, or the aforementioned electric field treatment system.
[0319] According to the tumor treatment device of the embodiment of the present disclosure, through the aforementioned electrode sheets such as 100L8 to 100L10, or the aforementioned electric field treatment system, it is possible to achieve 100% coverage of temperature detectors such as 114L8 to 114L10 while controlling the number of cable cores, thereby avoiding excessive weight on the electrode sheets such as 100L8 to 100L10 and maintaining the application effect of the electrode sheets such as 100L8 to 100L10.
[0320] The present disclosure also provides a computer-readable storage medium (not shown) on which a temperature detection program of the electric field therapy system is stored. When the temperature detection program of the electric field therapy system is executed by a processor (not shown), the aforementioned electrode patch identification method of the electric field therapy system is implemented.
[0321] According to the computer-readable storage medium of the embodiment of the present disclosure, through the aforementioned temperature detection method of the electric field therapy system, the coverage rate of temperature detectors such as 114L8 to 114L10 can be effectively increased while controlling the number of cable cores, thereby avoiding excessive weight on electrode sheets such as 100L8 to 100L10 and maintaining the application effect of electrode sheets such as 100L8 to 100L10.
[0322] The present disclosure also provides a third adapter of an electric field therapy system, such as 500L8 to 500L10, which includes a memory (not shown), a processor (not shown), and a temperature detection program of the electric field therapy system stored in the memory (not shown) and executable on the processor (not shown). When the processor executes the temperature detection program of the electric field therapy system, the aforementioned temperature detection method of the electric field therapy system is implemented.
[0323] According to the third adapter of the electric field therapy system of the embodiment of the present disclosure, such as 500L8 to 500L10, through the aforementioned temperature detection method of the electric field therapy system, it is possible to effectively increase the coverage rate of temperature detectors such as 114L8 to 114L10 while controlling the number of cable cores, thereby avoiding excessive weight on the electrode sheet and maintaining the application effect of the electrode sheet.
[0324] The present disclosure also provides a second adapter of an electric field therapy system, such as 400L8 to 400L10, which includes a memory (not shown), a processor (not shown), and a temperature detection program of the electric field therapy system stored in the memory (not shown) and executable on the processor (not shown).

[0326] The present disclosure also provides an electric field generator for an electric field therapy system, such as 300L8 to 300L10, which includes a memory (not shown), a processor (not shown), and a temperature detection program for the electric field therapy system stored in the memory (not shown) and executable on the processor (not shown). When the processor (not shown) executes the temperature detection program for the electric field therapy system, the aforementioned temperature detection method for the electric field therapy system is implemented.
[0327] Fourth Embodiments
[0328] FIG27 is a schematic diagram of an electric field therapy system according to one embodiment of the present application. As shown in FIG27 , the electric field therapy system includes: at least one pair of electrode sheets 100L11, a fourth adapter 600L11 connected to the at least one pair of electrode sheets 100L11, and an electric field generator 300L11 connected to the fourth adapter 600L11. The at least one pair of electrode sheets 100L11 can be placed on the patient's body surface in pairs, such as the four electrode sheets 100L11 in FIG27 , where each pair of electrode sheets 100L11 is placed on the patient's body surface as a pair. The electric field generator 300L11 is used to supply power to the at least one pair of electrode sheets 100L11, causing the at least one pair of electrode sheets 100L11 to generate an alternating electric field for treating tumors. The fourth adapter 600L11 is electrically connected between at least one pair of electrode sheets 100L11 and the electric field generator 300L11, and is used to transmit the alternating electrical signal generated by the electric field generator 300L11 to the at least one pair of electrode sheets 100L11. In other words, the electric field generator 300L11 is capable of generating an alternating electrical signal, which is transmitted to each electrode sheet 100L11 via the fourth adapter 600L11, thereby generating an alternating electric field for tumor treatment between the same pair of electrode sheets 100L11, thereby applying the alternating electric field to the patient's tumor site for tumor treatment.
[0329] As shown in FIG27 , in this embodiment, there are four electrode sheets 100L11, each of which includes an equal number of electrode elements 112L11. Each electrode element 112L11 is electrically connected to the fourth adapter 600L11, and the number of electrode elements 112L11 on each electrode sheet 100L11 is 20. In other embodiments, the electric field therapy system may include more or fewer electrode sheets 100L11; in other embodiments, each pair of electrode sheets 100L11 may include the same number of electrode elements 112L11, while different pairs of electrode sheets 100L11 may include different numbers of electrode elements 112L11; in still other embodiments, the number of electrode elements 112L11 on each electrode sheet 100L11 may be 9, 13, or the like.
[0330] Figures 29 and 30 are schematic diagrams of the circuit connection between the electrode sheet 100L11 and the fourth adapter 600L11 in two operating states of the electric field therapy system shown in Figure 27. It is important to note that the arrangement of the electrode elements 112L11 shown in Figures 29 and 30 is intended to more clearly illustrate the electrical connection between a single electrode sheet 100L11 and the fourth adapter 600L11. The arrangement of the electrode elements 112L11 shown in Figures 29 and 30 does not represent the spatial arrangement of the electrode elements 112L11. Referring to Figures 27, 29, and 30, the electrode sheet 100L11 includes a flexible circuit board 120L11, a plurality of electrode elements 112L11 electrically connected to the flexible circuit board 120L11 at intervals, a plurality of temperature sensors 114L11, and a first cable 130L11 electrically connected to the flexible circuit board 120L11. The flexible circuit board 120L11 can be a flexible circuit board. The flexible circuit board 120L11 is embedded with multiple conductive traces, including multiple first ground traces 121L11A and multiplexed signal traces 121L11B. The first cable 130L11 comprises multiple conductors (not shown), each of which is electrically connected to one of the multiple first ground traces 121L11A and multiplexed signal traces 121L11B on the flexible circuit board 120L11. In this embodiment, the total number of first ground traces 121L11A and dual-purpose signal traces 121L11B embedded in the flexible circuit board 120L11 does not exceed 10, and therefore the number of conductors in the first cable 130L11 does not exceed 10.
[0331] The multiple electrode elements 112L11 are arranged into multiple row groups and multiple column groups. In this embodiment, each electrode sheet 100L11 is provided with 20 electrode elements 112L11. The 20 electrode elements 112L11 are arranged in the order of 1 to 20 for circuit connection, divided into four row groups and five column groups. That is, the 20 electrode elements 112L11 are arranged in four rows and five columns for circuit connection. Each electrode element 112L11 corresponds to a temperature detector 114L11. Each temperature detector 114L11 has a signal terminal 114L11B and a ground terminal 114L11A. The electrode elements 112L11 and the temperature detectors 114L11 are both soldered to the flexible circuit board 120L11, and the electrode elements 112L11 are short-circuited with the signal terminals 114L11B of the corresponding temperature detectors 114L11. The electrode element 112L11 and the corresponding temperature detector 114L11 together constitute an electrode unit (unnumbered). Since the multiple temperature detectors 114L11 are arranged in a one-to-one correspondence with the multiple electrode elements 112L11, the multiple temperature detectors 114L11 are also arranged in four rows and five columns in terms of circuit connection. It should be noted that the arrangement here is to more clearly show the electrical connection between the electrode sheet 100L11 and the fourth adapter 600L11, and does not represent the arrangement of the electrode element 112L11 in the spatial structure. Its spatial structure may be a roughly array structure as shown in Figure 28, or other structures, such as petal-shaped or scattered shapes, etc., which may be regular or irregular. The electrode element 112L11 is configured to apply an alternating electric field to the patient's tumor site. Temperature detector 114L11 is configured to detect the temperature of the patient's body surface applied to electrode sheet 100L11, namely, the temperature at the corresponding electrode element 112L11, and output a detection signal to fourth adapter 600L11. In this embodiment, dual-purpose signal lines 121L11B of flexible circuit board 120L11 are provided in a one-to-one correspondence with multiple column groups of electrode elements 112L11. These dual-purpose signal lines 121L11B are configured to transmit the alternating electrical signal generated by electric field generator 300L11 to each electrode element 112L11 in the corresponding column group. Specifically, electrode elements 112L11 in the same column group are short-circuited via the same dual-purpose signal line 121L11B of flexible circuit board 120L11, while electrode elements 112L11 in different column groups are connected in parallel via different dual-purpose signal lines 121L11B of flexible circuit board 120L11. The dual-purpose signal line 121L11B of the flexible circuit board 120L11 is electrically connected to the first cable 130L11 and then to the electric field generator 300L11 via the fourth adapter 600L11. Furthermore, the dual-purpose signal line 121L11B of the flexible circuit board 120L11 receives the alternating electrical signal generated by the electric field generator 300L11 via the first cable 130L11 and the fourth adapter 600L11.
[0332] Multiple first grounding lines 121L11A are provided in a one-to-one correspondence with multiple row groups of electrode elements 112L11. These first grounding lines 121L11A are used to sequentially short-circuit each temperature detector 114L11 in each row group to ground. Specifically, the grounding terminals 114L11A of the temperature detectors 114L11 in the same row group are all short-circuited via the same first grounding line 121L11A on the flexible circuit board 120L11. The grounding terminals 114L11A of the temperature detectors 114L11 in different row groups are connected in parallel via different first grounding lines 121L11A on the flexible circuit board 120L11. During the temperature detection period, only one of the multiple first grounding lines 121L11A is conductive at any given time; the other three are disconnected.
[0333] Each of the multiplexed dual-purpose signal lines 121L11B is further configured to short-circuit the signal terminal 114L11B of at most one temperature detector 114L11 in each row group to an external device for receiving a detection signal, wherein the signal terminals 114L11B of the temperature detectors 114L11 connected to each of the multiplexed dual-purpose signal lines 121L11B are different from each other to avoid subsequent output of duplicate signals by the dual-purpose signal line 121L11B. Specifically, when the number of electrode elements 112L11 in a row group is the same as the number of dual-purpose signal lines 121L11B, each dual-purpose signal line 121L11B is electrically connected to the signal terminal 114L11B of a different temperature detector 114L11 in the row group. When the number of electrode elements 112L11 in a row group is less than the number of dual-purpose signal lines 121L11B, at least one dual-purpose signal line 121L11B is not electrically connected to the signal terminal 114L11B of a temperature detector 114L11. The remaining dual-purpose signal lines 121L11B are each electrically connected to the signal terminal 114L11B of a different temperature detector 114L11 in the row group. In this embodiment, the external device for receiving the detection signal is a fourth adapter 600L11. The signal terminals 114L11B of the temperature detectors 114L11 in different column groups are connected in parallel via different dual-purpose signal lines 121L11B of the flexible circuit board 120L11. The signal terminals 114L11B of the temperature detectors 114L11 in the same column group are all short-circuited to the same dual-purpose signal line 121L11B of the flexible circuit board 120L11.
[0334] In this embodiment, each electrode element 112L11 is equipped with a temperature detector 114L11 for temperature detection. The aforementioned circuit design reduces the number of conductors in the first cable 130L11, preventing cable thickness and stiffness that would increase the difficulty of securing the cable. This also prevents the increased number of conductors in the first cable 130L11 from affecting the adhesion between the electrode sheet 100L11 and the patient's body surface corresponding to the tumor site. The flexible circuit board 120L11 includes nine first grounding wires 121L11A and two dual-purpose signal wires 121L11B. Specifically, in this embodiment, the flexible circuit board 120L11 includes four first grounding wires 121L11A and five dual-purpose signal wires 121L11B. The number of first grounding wires 121L11A is related to the number M of row groups of electrode elements 112L11 and is greater than or equal to the number of row groups of electrode elements 112L11, where M is a positive integer. The number of dual-purpose signal lines 121L11B is related to the number N of column groups of electrode elements 112L11, which is greater than or equal to the number N of column groups of electrode elements 112L11, where N is a positive integer. The number of lines L embedded within the flexible circuit board 120L11 of the electrode sheet 100L11 is equal to the sum of the number of first ground lines 121L11A and the number of dual-purpose signal lines 121L11B. In this embodiment, the number of first ground lines 121L11A is equal to the number M of row groups of electrode elements 112L11, and the number of dual-purpose signal lines 121L11B is equal to the number N of column groups of electrode elements 112L11.
[0335] Multiple electrode elements 112L11 are arranged in a roughly two-dimensional array on a flexible circuit board 120L11 at intervals. As shown in FIG28 , the electrode sheet 100L11 in this embodiment includes 20 electrode elements 112L11 and 20 corresponding temperature sensors 114L11. The 20 electrode elements 112L11 are arranged in an array of four rows and six columns. The first and fourth rows each contain four electrode elements 112L11, while the second and third rows each contain six electrode elements 112L11. The four electrode elements 112L11 in each of the first and fourth rows are located in columns 2 through 5, while the six electrode elements 112L11 in each of the second and third rows are located in columns 1 through 6. The four electrode elements 112L11 in the first row are divided into Region 1. The electrode elements 112L11 in the first column of the second row, the first column of the third row, and the second and third columns of the fourth row are divided into Region 2. The electrode elements 112L11 in the sixth column of the second row, the sixth column of the third row, and the fourth and fifth columns of the fourth row are divided into Region 3. The electrode elements 112L11 in the second and third columns of the second row and the second and third columns of the third row are divided into Region 4. The electrode elements 112L11 in the fourth and fifth columns of the second row and the fourth and fifth columns of the third row are divided into Region 5. Each region (1-5) corresponds to a column group. In other embodiments, the 20 electrode elements 112L11 may also be arranged in other ways. Of course, in other embodiments, the electrode sheet 100L11 may also have other numbers of electrode elements 112L11. In short, the implementation of the present application is not limited by the number and arrangement of the electrode elements 112L11 of the electrode sheet 100L11.
[0336] Each electrode element 112L11 can apply an alternating electrical signal, and the electrode sheets 100L11 configured in pairs are used to apply an alternating electric field to the patient's tumor site. Optionally, the electrode element 112L11 is a dielectric element, such as a ceramic sheet, or a polymer dielectric layer composed of a polymer material. Each temperature detector 114L11 is provided corresponding to an electrode element 112L11 to detect the temperature at the corresponding electrode element 112L11. Each temperature detector 114L11 can be provided at any position of the corresponding electrode element 112L11. In this embodiment, each electrode element 112L11 is provided with an opening 1120L11, and the opening 1120L11 is suitable for installing the temperature detector 114L11. For example, the middle part of each electrode element 112L11 has an opening 1120L11 provided therethrough, and the opening 1120L11 of each electrode element 112L11 accommodates a corresponding temperature detector 114L11. Each temperature detector 114L11 is also connected in series with a first diode 115L11. First diode 115L11 has an anode 115L11B and a cathode 115L11A. Anode 115L11B of first diode 115L11 is connected to ground terminal 114L11A of temperature detector 114L11, while cathode 115L11A of first diode 115L11 is connected to a corresponding first ground line 121L11A. Signal terminal 114L11B of temperature detector 114L11 is connected to a corresponding dual-purpose signal line 121L11B. Temperature detector 114L11 may be a thermistor or other temperature sensor. Each temperature detector 114L11 corresponds to a first diode 115L11. This first diode 115L11 is connected in series with the temperature detector 114L11 of the same electrode element 112L11 to block reverse current flow, thereby preventing detection signals from other electrode elements 112L11 from affecting the temperature detector 114L11. The electrode unit (not numbered) may also include a first diode 115L11.
[0337] As shown in FIG29 or FIG30 , electrode sheet 100L11 of this embodiment includes four first grounding lines 121L11A. Each first grounding line 121L11A is used to ground the ground terminals 114L11A of temperature detectors 114L11 in the same row group, or to ground the cathodes 115L11A of first diodes 115L11 connected in series with temperature detectors 114L11 in the same row group. The four first grounding lines 121L11A of electrode sheet 100L11 are first grounding line 121L11A-1, first grounding line 121L11A-2, first grounding line 121L11A-3, and first grounding line 121L11A-4. Among the four row groups of electrode sheet 100L11, the first row group is electrode elements 112L11-1 to 112L11-5, the second row group is electrode elements 112L11-6 to 112L11-10, the third row group is electrode elements 112L11-11 to 112L11-15, and the fourth row group is electrode elements 112L11-16 to 112L11-20. Specifically, the first grounding line 121L11A-1 is used to ground the electrode elements 112L11-1 to 112L11-5 in the first row group; the first grounding line 121L11A-2 is used to ground the electrode elements 112L11-6 to 112L11-10 in the second row group; the first grounding line 121L11A-3 is used to ground the electrode elements 112L11-11 to 112L11-15 in the third row group; and the first grounding line 121L11A-4 is used to ground the electrode elements 112L11-16 to 112L11-20 in the fourth row group. It should be noted that these first ground lines 121L11A can be selectively closed or opened. This can be achieved by connecting each first ground line 121L11A in series with a control switch 640L11. Specifically, the ground terminals 114L11A of the temperature detectors 114L11 corresponding to each electrode element 112L11 in each row group are collectively connected to a ground pin via a control switch 640L11. This will be described in detail below. The phrase "grounding the electrode element 112L11" mentioned above can refer to grounding the ground terminals 114L11A of the temperature detectors 114L11 corresponding to each electrode element 112L11, or it can refer to connecting the first diode 115L11 in series with the temperature detector 114L11 corresponding to the same electrode element 112L11, thereby grounding them together. In short, each first ground line 121L11A short-circuits the ground terminals 114L11A of all the temperature detectors 114L11 corresponding to each electrode element 112L11 in each row group, connecting them to ground. The control switch in this embodiment is also the first switch in the aforementioned embodiment.
[0338] As shown in Figures 29 and 30 , the electrode sheet 100L11 of this embodiment further includes five dual-purpose signal lines 121L11B. One end of each dual-purpose signal line 121L11B is connected to all electrode elements 112L11 in each column group, and the other end is connected to a fourth adapter 600L11 for receiving detection signals and transmitting alternating electrical signals. In other words, for each row group, each dual-purpose signal line 121L11B can be connected to one of the electrode elements 112L11 or not connected to any electrode element 112L11 in that row group, thereby preventing the dual-purpose signal line 121L11B from subsequently outputting duplicate signals. Specifically, the five dual-purpose signal lines 121L11B of the electrode sheet 100L11 include a first dual-purpose signal line 121L11B- 1 , a second dual-purpose signal line 121L11B- 2 , a third dual-purpose signal line 121L11B- 3 , a fourth dual-purpose signal line 121L11B- 4 , and a fifth dual-purpose signal line 121L11B- 5 . One end of the first dual-purpose signal line 121L11B-1 is connected to the four electrode elements 112L11, namely, electrode element 112L11-1, electrode element 112L11-6, electrode element 112L11-11, and electrode element 112L11-16, and the signal end 114L11B of the temperature detector 114L11 corresponding to each of them. One end of the second dual-purpose signal line 121L11B-2 is connected to the four electrode elements 112L11, namely, electrode element 112L11-2, electrode element 112L11-7, electrode element 112L11-12, and electrode element 112L11-17, and the signal end 114L11B of the temperature detector 114L11 corresponding to each of them. One end of the third dual-purpose signal line 121L11B-3 is connected to the electrode elements 112L11-3, electrode element 112L11-8, and electrode element 112L11-17 corresponding to each of them. 1-13, electrode elements 112L11-18, four electrode elements 112L11 and their corresponding signal ends 114L11B of temperature detectors 114L11; one end of the fourth dual-purpose signal line 121L11B-4 is respectively connected to the four electrode elements 112L11, electrode elements 112L11-4, electrode elements 112L11-9, electrode elements 112L11-14, and electrode elements 112L11-19, and their corresponding signal ends 114L11B of temperature detectors 114L11; one end of the fifth dual-purpose signal line 121L11B-5 is respectively connected to the four electrode elements 112L11, electrode elements 112L11-5, electrode elements 112L11-10, electrode elements 112L11-15, and electrode elements 112L11-20, and their corresponding signal ends 114L11B of temperature detectors 114L11.In short, each dual-purpose signal line 121L11B parallel-connects the electrode elements 112L11 in the same column group and the signal terminals 114L11B of their corresponding temperature detectors 114L11, allowing connection to external devices. It should be noted that these dual-purpose signal lines 121L11B can selectively transmit alternating electrical signals or receive detection signals. This is achieved by connecting each dual-purpose signal line 121L11B in series with a bidirectional switch 690L11 and coordinating the opening and closing of the first ground line 121L11A. That is, after the signal terminals 114L11B of the temperature detectors 114L11 in each column group are short-circuited with the corresponding electrode elements 112L11, they are collectively connected to a switching unit (unnumbered) via a dual-purpose signal line 121L11B. The switching unit (unnumbered) includes a plurality of bidirectional switches 690L11, which are configured to switch the dual-purpose signal line 121L11B to a temperature sampling point (unnumbered) or an alternating power line 700L11. When the dual-purpose signal line 121L11B is connected to the temperature sampling point (unnumbered), the switch state of the switches 690L11 is configured so that the detection signal detected by the corresponding temperature detector 114L11 in each row group is sampled based on the temperature sampling point (unnumbered). Furthermore, when the dual-purpose signal line 121L11B is connected to the alternating power line 700L11, an alternating electrical signal is applied to the electrode elements 112L11 of at least one column group based on the alternating power line 700L11. This will be described in detail below.
[0339] Multiple first ground lines 121L11A and multiplexed signal lines 121L11B are conductive traces embedded within the flexible printed circuit board 120L11. The flexible printed circuit board 120L11 is electrically connected to the first cable 130L11. Multiple first ground lines 121L11A and multiplexed signal lines 121L11B embedded within the flexible printed circuit board 120L11 are each electrically connected to a corresponding wire (not shown) within the first cable 130L11.
[0340] The electric field therapy system of this embodiment includes at least one pair of the aforementioned electrode sheets 100L11, a fourth adapter 600L11 electrically connected to the electrode sheets 100L11, and an electric field generator 300L11 electrically connected to the fourth adapter 600L11. The fourth adapter 600L11 is connected between the electrode sheets 100L11 and the electric field generator 300L11. The electric field generator 300L11 provides alternating electrical signals to the multiple electrode elements 112L11 of the electrode sheet 100L11 or receives detection signals from temperature detectors 114L11 corresponding to the multiple electrode elements 112L11 via the fourth adapter 600L11 and the dual-purpose signal line 121L11B of the electrode sheet 100L11. The fourth adapter 600L11 transmits the alternating electric signal generated by the electric field generator 300L11 to the dual-purpose signal line 121L11B of the electrode sheet 100L11 and is also configured to receive the detection signal output by the multiplexed signal line 121L11B of the electrode sheet 100L11.
[0341] Referring to Figures 29 and 30, the fourth adapter 600L11 includes: a fourth controller 610L11, multiple groups of third analog-to-digital converters 620L11 connected to the fourth controller 610L11, multiple groups of second voltage-dividing resistors 630L11 and multiple groups 640L11 corresponding one-to-one to the multiple groups of third analog-to-digital converters 620L11, multiple groups of bidirectional switches 690L11 connected one-to-one to the multiple groups of third analog-to-digital converters 620L11, a fifth communication unit 650L11, an alternating power line 700L11 connected one-to-one to each group of bidirectional switches 690L11, and a first power supply module 710L11 connected to the fifth communication unit 650L11, the fourth controller 610L11 and the multiple groups of third analog-to-digital converters 620L11. The first power supply module 710L11 provides a DC power supply VCC for each electronic component of the fourth adapter 600L11. The fourth adapter 600L11 also includes multiple circuit lines (unnumbered), which are electrically connected one-to-one with the multiple first ground lines 121L11A and the multiple dual-purpose signal lines 121L11B in the flexible circuit board 120L11 of the corresponding electrode sheet 100L11 through the first cable 130L11 of the corresponding electrode sheet 100L11. The multiple circuit lines (unnumbered) include multiple alternating power lines 700L11 that transmit alternating electrical signals to the corresponding electrode sheets 100L11 and are electrically connected to the dual-purpose signal lines 121L11B in the flexible circuit board 120L11 of the corresponding electrode sheet 100L11, multiple circuit lines (unnumbered) that are electrically connected one-to-one with the dual-purpose signal lines 121L11B in the flexible circuit board 120L11 of the corresponding electrode sheet 100L11 and are used to supply power to the temperature detectors 114L11 of the electrode sheet 100L11 or transmit the detection signals of the electrode sheet 100L11, and multiple circuit lines (unnumbered) that are electrically connected one-to-one with the multiple first ground lines 121L11A in the flexible circuit board 120L11 of the corresponding electrode sheet 100L11. The number L of circuit lines electrically connected between the fourth adapter 600L11 and one electrode sheet 100L11 is equal to the sum of the number of rows and columns of the electrode elements 112L11 of the electrode sheet 100L11; the number H of circuits electrically connected between the fourth adapter 600L11 and X electrode sheets 100L11 is equal to X times the number of circuit lines electrically connected to a single electrode sheet 100L11, that is, H=XL=X*(M+N). The number of groups of 640L11 and the number of groups of the two-way switching switches 690L11 are both related to the number of electrode sheets 100L11. The number of groups of 640L11 is the same as the number of groups of the two-way switching switches 690L11, and is not less than the number of electrode sheets 100L11. Optionally, the number of groups of 640L11 and the number of groups of the two-way switching switches 690L11 are the same as the number of electrode sheets 100L11.The following describes in detail the electrical connection between an electrode sheet 100L11 having 20 electrode elements 112L11 and the fourth adapter 600L11 as an example.
[0342] Each group 640L11 includes multiple 640L11s. Each of the 640L11s is connected to the fourth adapter 600L11 and electrically connected to circuit lines (not numbered) corresponding to the multiple first ground lines 121L11A of a corresponding electrode sheet 100L11. The circuit lines (not numbered) electrically connected to the multiple first ground lines 121L11A of each electrode sheet 100L11 are grounded at one end near the 640L11. The number of 640L11s in each group 640L11 is related to the number of first ground lines 121L11A of the flexible circuit board 120L11 of the corresponding electrode sheet 100L11, and in this embodiment, the number of 640L11s is equal to the number of first ground lines 121L11A of the flexible circuit board 120L11.

At this time, the detection signals collected by each temperature detector 114L11 corresponding to each electrode element 112L11 in each row group of the electrode sheet 100L11 can be collected in a time-sharing manner through multiple detection channels A, B, C, D, and E of a group of third analog-to-digital converters 620L11 corresponding to the electrode sheet 100L11.

The five bidirectional switches 690L11 in a group corresponding to the third analog-to-digital converter 620L11 are all switched to their respective terminals 1, so that each dual-purpose signal line 121L11B of the electrode sheet 100L11 is electrically connected to the corresponding detection channels A, B, C, D, and E of the corresponding third analog-to-digital converter 620L11. With this configuration, the third analog-to-digital converter 620L11 can collect voltage values from all temperature detectors 114L11 corresponding to each electrode element 112L11 in the same row group that is short-circuited with the first ground line 121L11A corresponding to the turned-on control switch 640L11.
