Abstract
Description
Technical Field
[0001] The present application relates to the technology of tumor treating fields (TTF), and particularly to an electrode patch, a tumor treating field system, a temperature detection method, and a signal application method. Background Art
[0002] Tumor treating fields is a method of treating tumors by applying a low-intensity medium-high frequency alternating electric field to prevent the formation of spindle microtubules during the mitosis of certain tumor cells, inhibit the separation of intracellular organelles during the cell division phase, and induce apoptosis of cells in the mitosis phase, thereby achieving the effect of treating tumors.
[0003] Compared with traditional cancer treatment methods, TTF has an innovative mechanism of action. Some physiological characteristics of tumor cells, such as geometric shape and high-frequency mitosis, make them vulnerable to TTF. TTF disrupts the normal aggregation of tubulin by applying a directional force on intracellular polar particles (such as macromolecules and organelles). These processes may lead to physical damage to the cell membrane and apoptosis. At the end of cell mitosis, the structural morphology of the cleavage furrow causes uneven distribution of the electric field around it. At the same time, under the influence of TTF, the electric field intensity at the cleavage furrow is significantly enhanced, and charged substances in the cell move towards the cleavage furrow, interfering with or even destroying the formation of the cell structure, ultimately leading to the failure of cell division and apoptosis.
[0004] In existing tumor treating field systems, an electric field application device is used to transmit an alternating current signal for tumor treating fields to an electrode patch, and then an alternating electric field is applied to the tumor site of a patient through the electrode patch for tumor treating fields. When the tumor treatment electric field is applied to the patient's body, heat will accumulate at the application site, and the temperature will also increase accordingly. Therefore, it is necessary to monitor the temperature at the application site. When the temperature is too high, it is necessary to adjust the electric field intensity in a timely manner to reduce the risk of scalding the patient's skin due to excessive temperature.
[0005] A tumor treating field system includes at least a pair of electrode patches, and there are multiple electrode units in each electrode patch. Even if the same alternating current signal is applied to each electrode unit, the heat generated on each electrode unit will vary depending on its location, that is, the temperature of each electrode unit on the entire electrode patch will not be exactly the same. In this way, it is possible that the temperature of some electrode units in the entire electrode patch exceeds the preset temperature, while the temperature of other electrode units is normal. In order to improve the effect of tumor treating fields, it is necessary to implement individual control over the over-temperature electrode units. However, for existing electrode patches, implementing individual control over electrode units requires setting a conductive trace for each electrode unit in the substrate of the electrode patch, which will increase the number of conductive traces in the substrate of the electrode patch, making the electrode patch difficult to bend, and the cable electrically connected to the electrode patch will also thicken, increasing the overall weight of the electrode patch, which is not conducive to the application of the electrode patch.
[0006] Therefore, it is necessary to provide an electrode sheet, a tumor electric field treatment system, a temperature detection method and a signal application method for partitioning and controlling a plurality of electrode units with fewer conductive traces. Summary of the Invention

Detailed implementation manners
[0126] The embodiments of the technical solution of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present application more clearly, and therefore are only examples and cannot be used to limit the protection scope of the present application.
[0127] Figure 1 Shown is a schematic diagram of the tumor electric field therapy system 100 of the present invention. As Figure 1 shown, the tumor electric field therapy system 100 includes: at least a pair of electrode plates 13, an adapter 20 connected to the electrode plates 13, and an electric field generator 30 connected to the adapter 20. The electric field generator 30 supplies power to the electrode plates 13 so that the electrode plates 13 generate a treatment electric field. The adapter 20 is electrically connected between the electrode plates 13 and the electric field generator 30 and is used to transmit the alternating current signal generated by the electric field generator 30 to the electrode plates 13. That is to say, the electric field generator 30 can generate an alternating current signal, and the generated alternating current signal is transmitted to each electrode plate 13 through the adapter 20, so as to generate a treatment electric field for treating tumors between the same pair of electrode plates 13. As Figure 1 shown, in this embodiment, the number of the electrode plates 13 is 4. Each electrode plate 13 includes a plurality of electrode units 33 with the same number, and each electrode unit 33 is electrically connected to the adapter 20. The number of the electrode units 33 on each electrode plate 13 is 20. In some other embodiments, the tumor electric field therapy system 100 may also have more or fewer electrode plates 13. In some other embodiments, each pair of electrode plates 13 has the same number of electrode units 33, and different pairs of electrode plates 13 may also have different numbers of electrode units 33.
[0128] Figure 3 With Figure 4 are schematic diagrams of the circuit connections between the electrode plates 13 and the adapter 20 in two working states of the tumor electric field therapy system 100. It should be noted that: Figure 3 With Figure 4 the arrangement of the electrode units 33 shown is to more clearly show the electrical connection situation between an electrode plate 13 and the adapter 20, Figure 3 With Figure 4 the arrangement of the electrode units 33 shown does not represent the arrangement of the electrode units 33 in the spatial structure. Combining Figure 1 , Figure 3 and Figure 4, the electrode sheet 13 includes: a flexible printed circuit board 31, a plurality of electrode units 33 electrically connected to the flexible printed circuit board 31 at intervals, and a first cable 15 electrically connected to the flexible printed circuit board 31. The flexible printed circuit board 31 is embedded with a plurality of conductive traces (18, 19), and the plurality of conductive traces (18, 19) includes a plurality of ground lines 18 and a plurality of dual-purpose signal lines 19. The first cable 15 has a plurality of core wires (not shown), and each core wire is electrically connected to the plurality of ground lines 18 and the plurality of dual-purpose signal lines 19 of the flexible printed circuit board 31 in one-to-one correspondence. The total number of the ground lines 18 and the dual-purpose signal lines 19 embedded in the flexible printed circuit board 31 does not exceed 10. Therefore, the number of wires of the first cable 15 does not exceed 10.
[0129] In this embodiment, 20 electrode units 33 are provided on each electrode sheet 13. The 20 electrode units 33 are sorted and grouped in the order of 1 to 20 in terms of circuit connection, and are divided into four row groups and five column groups, that is, the 20 electrode units 33 are arranged in four rows and five columns in terms of circuit connection. Each electrode unit 33 includes: a dielectric element 35 and a temperature sensor 34. The temperature sensor 34 includes a ground terminal 34-1 and a signal terminal 34-2. The dielectric element 35 and the temperature sensor 34 are both welded to the flexible printed circuit board 31, and the dielectric element 35 is short-circuited with the signal terminal 34-2 of the corresponding temperature sensor 34. Since the plurality of temperature sensors 34 are provided in one-to-one correspondence with the plurality of electrode units 33, the plurality of temperature sensors 34 are also arranged in four row groups and five column groups in terms of circuit connection. It should be noted that this arrangement is to more clearly show the electrical connection between the electrode sheet 13 and the adapter 20, and does not represent the arrangement of the electrode units 33 in the spatial structure. The spatial structure may be as Figure 2The shown substantially array-like structure can also be other structures, such as petal-shaped or scattered, etc., and can be regular or irregular structures. The dielectric element 35 is configured to apply an alternating electric field to the patient's tumor site. The temperature sensor 34 is configured to detect the temperature of the patient's body surface in contact with the electrode patch 13 and output a temperature detection signal to the adapter 20. In this embodiment, the multi-purpose signal lines 19 of the flexible printed circuit board 31 are respectively arranged in one-to-one correspondence with multiple column groups of the electrode unit 33, and are configured to transmit the alternating current signal generated by the electric field generator 30 to the dielectric elements 35 in each electrode unit 33 in the corresponding column group. That is, the dielectric elements 35 in the same column group are all short-circuited through the same multi-purpose signal line 19 of the flexible printed circuit board 31, and the dielectric elements 35 in different column groups are respectively connected in parallel through different multi-purpose signal lines 19 of the flexible printed circuit board 31. The multi-purpose signal line 19 of the flexible printed circuit board 31 is electrically connected to the first cable 15 and then electrically connected to the electric field generator 30 via the adapter 20. Further, the multi-purpose signal line 19 of the flexible printed circuit board 31 receives the alternating current signal generated by the electric field generator 30 through the first cable 15 and the adapter 20.
[0130] The multiple ground wires 18 are respectively arranged in one-to-one correspondence with multiple row groups of the electrode unit 33, and the multiple ground wires 18 are respectively used to short-circuit and ground the temperature sensors 34 of the corresponding electrode units 12 in each row group in sequence. That is, the respective ground terminals 34-1 of the multiple temperature sensors 34 in the same row group are all short-circuited through the same ground wire 18 of the flexible printed circuit board 31, and the respective ground terminals 34-1 of the temperature sensors 34 in different row groups are respectively connected in parallel through different ground wires 18 of the flexible printed circuit board 31. During the period of temperature detection, only one of the multiple ground wires 18 is conducting at the same moment, and the other three are disconnected.
[0131] Each path of the multi-purpose signal line 19 is also configured to short-circuit the signal terminal 34-2 of the temperature sensor 34 of at most one electrode unit 33 in each row group to an external device for receiving a detection signal. Among them, the signal terminals 34-2 of the temperature sensors 34 connected by each path of the multi-purpose signal line 19 are different from each other to avoid the subsequent output of repeated signals by the multi-purpose signal line 19. That is, when the number of electrode units 33 in a row group is the same as the number of paths of the multi-purpose signal line 19, each path of the multi-purpose signal line 19 is electrically connected to the signal terminal 34-2 of the temperature sensor 34 of a different one of the electrode units 33 in this row group respectively; when the number of electrode units 33 in a row group is less than the number of paths of the multi-purpose signal line 19, there is at least one path of the multi-purpose signal line 19 that is not electrically connected to the signal terminal 34-2 of the temperature sensor 34 of the electrode unit 33, and each of the remaining paths of the multi-purpose signal line 19 is electrically connected to the signal terminal 34-2 of a different one of the electrode units 33 in this row group respectively. In this embodiment, the external device for receiving the detection signal is an adapter 20. The signal terminals 34-2 of the multiple temperature sensors 34 located in different column groups are respectively connected in parallel through different paths of the multi-purpose signal line 19 of the flexible circuit board 31, and the signal terminals 34-2 of the multiple temperature sensors 34 located in the same column group are all short-circuited to the same path of the multi-purpose signal line 19 of the flexible circuit board 31.
[0132] In this embodiment, when a temperature sensor 34 is configured for each electrode unit 33 to perform temperature detection, the above circuit design is adopted to reduce the number of wires of the first cable 15, avoid the cable becoming thicker and the softness of the cable becoming harder, which increases the difficulty of cable fixing; at the same time, avoid the increase in the number of wires of the first cable 15 affecting the adhesion effect between the electrode patch 13 and the corresponding body surface of the patient's tumor site. The ground wire 18 and the multi-purpose signal line 19 embedded in the flexible circuit board 31 are a total of 9 paths of circuits. Specifically, in this embodiment, the ground wire 18 embedded in the flexible circuit board 11 is 4 paths of circuits, and the multi-purpose signal line 19 is 5 paths of circuits. The number of the ground wires 18 is related to the number of row groups M of the electrode units 33, which is greater than or equal to the number of row groups of the electrode units 33, and M is a positive integer. The number of the multi-purpose signal lines 19 is related to the number of column groups N of the electrode units 33, which is greater than or equal to the number of column groups of the electrode units 33, and N is a positive integer. The number of circuits L embedded in the flexible circuit board 31 of the electrode patch 13 is equal to the sum of the number of the ground wires 18 and the number of the multi-purpose signal lines 19. In this embodiment, the number of the ground wires 18 is equal to the number of row groups M of the electrode units 33; the multi-purpose signal line 19 is equal to the number of column groups N of the electrode units 33.
[0133] The multiple electrode units 33 are arranged at intervals in a substantially two-dimensional array form on the flexible circuit board 31. As Figure 2As shown, the electrode sheet 13 in this embodiment includes 20 electrode units 33 and 20 temperature sensors 34 corresponding to the electrode units 33. The 20 electrode units 33 are arranged in a four-row and six-column array. Both the first row and the fourth row have four electrode units 33, and both the second row and the third row have six electrode units 33. The four electrode units 33 in each of the first row and the fourth row are located in the columns from the second column to the fifth column, and the six electrode units 33 in each of the second row and the third row are located in the columns from the first column to the sixth column. The 4 electrode units 33 in the first row are divided into region 1, the electrode units 33 in the first column of the second row, the first column of the third row, the second column and the third column of the fourth row are divided into region 2, the electrode units 33 in the sixth column of the second row, the sixth column of the third row, the fourth column and the fifth column of the fourth row are divided into region 3, the electrode units 33 in the second column and the third column of the second row and the second column and the third column of the third row are divided into region 4, and the electrode units 33 in the fourth column and the fifth column of the second row and the fourth column and the fifth column of the third row are divided into region 5. Each region (1 - 5) corresponds to a column group respectively. In some other embodiments, the 20 electrode units 33 can also be arranged in other ways. Of course, in some other embodiments, the electrode sheet 13 can also have other numbers of electrode units 33. In short, the implementation of the present invention is not limited by the number and arrangement form of the electrode units 33 of the electrode sheet 13.
[0134] Each electrode unit 33 includes a dielectric element 35 and a temperature sensor 34. In Figure 3 and Figure 4 the embodiment shown, the dielectric element 35 can be a dielectric ceramic sheet or a polymer dielectric layer made of a polymer material. The temperature sensor 34 can be a thermistor element. Of course, in some other embodiments, the temperature sensor 34 can also be other temperature sensors other than thermistors, and it can be set at any position on the electrode unit 33. In this embodiment, each dielectric element 35 has a through hole (not labeled) penetrating through the middle, and a corresponding temperature sensor 34 is received in the through hole (not labeled) of each dielectric element 35. Each electrode unit 33 can also include a diode 36. The diode 36 is connected in series with the temperature sensor 34 of the same electrode unit 33, and it can prevent the reverse inflow of current to prevent the detection signal from other electrode units 33 from affecting this temperature sensor 34.
[0135] Figure 3 or Figure 4As shown, the electrode sheet 13 of this embodiment includes four ground wires 18, and each ground wire 18 is used to ground the ground terminals 34-1 of the temperature sensors 34 in the same row group. The four ground wires 18 of the electrode sheet 13 are respectively a first ground wire 18-1, a second ground wire 18-2, a third ground wire 18-3, and a fourth ground wire 18-4. Among the four row groups of the electrode sheet 13, the first row group is electrode units 33-1 to 33-5, the second row group is electrode units 33-6 to 33-10, the third row group is electrode units 33-11 to 33-15, and the fourth row group is electrode units 33-16 to 33-20. Specifically, the first ground wire 18-1 is used to ground electrode units 33-1 to 33-5 in the first row group; the second ground wire 18-2 is used to ground electrode units 33-6 to 33-10 in the second row group; the third ground wire 18-3 is used to ground electrode units 33-11 to 33-15 in the third row group; the fourth ground wire 18-4 is used to ground electrode units 33-16 to 33-20 in the fourth row group. It should be noted that these ground wires 18 can be selectively closed or disconnected, which can be achieved by connecting each ground wire 18 in series with a switch respectively, and this will be described in detail below. The above "grounding the electrode unit 33" can refer to grounding the ground terminal 34-1 of the temperature sensor 34 in the electrode unit 33, or it can also refer to the diode 36 being connected in series with the temperature sensor 34 of the same electrode unit 33 and being grounded together. In short, each ground wire 18 shorts and grounds the ground terminals 34-1 of the temperature sensors 34 of all the electrode units 33 in each row group.
[0136] Figure 3 or Figure 4As shown, the electrode sheet 13 of this embodiment further includes five two-purpose signal lines 19. One end of each two-purpose signal line 19 is respectively connected to all the electrode units 33 in each column group, and the other end is connected to an adapter 20 for receiving temperature detection signals and transmitting alternating current signals. That is to say, for each row group, each two-purpose signal line 19 can choose to connect to one of the electrode units 33 or not connect to any of the electrode units 33 in this row group to avoid the two-purpose signal line 19 from outputting duplicate signals subsequently. Specifically, the five two-purpose signal lines 19 of the electrode sheet 13 include a first two-purpose signal line 19-1, a second two-purpose signal line 19-2, a third two-purpose signal line 19-3, a fourth two-purpose signal line 19-4, and a fifth two-purpose signal line 19-5. One end of the first two-purpose signal line 19-1 is respectively and simultaneously connected to the signal terminals 34-2 of the dielectric elements 35 and the respective temperature sensors 34 of the four electrode units 33, namely the electrode unit 33-1, the electrode unit 33-6, the electrode unit 33-11, and the electrode unit 33-16; one end of the second two-purpose signal line 19-2 is respectively and simultaneously connected to the signal terminals 34-2 of the dielectric elements 35 and the respective temperature sensors 34 of the four electrode units 33, namely the electrode unit 33-2, the electrode unit 33-7, the electrode unit 33-12, and the electrode unit 33-17; one end of the third two-purpose signal line 19-3 is respectively and simultaneously connected to the signal terminals 34-2 of the dielectric elements 35 and the respective temperature sensors 34 of the four electrode units 33, namely the electrode unit 33-3, the electrode unit 33-8, the electrode unit 33-13, and the electrode unit 33-18; one end of the fourth two-purpose signal line 19-4 is respectively and simultaneously connected to the signal terminals 34-2 of the dielectric elements 35 and the respective temperature sensors 34 of the four electrode units 33, namely the electrode unit 33-4, the electrode unit 33-9, the electrode unit 33-14, and the electrode unit 33-19; one end of the fifth two-purpose signal line 19-5 is respectively connected to the signal terminals 34-2 of the dielectric elements 35 and the temperature sensors 34 of the four electrode units 33, namely the electrode unit 33-5, the electrode unit 33-10, the electrode unit 33-15, and the electrode unit 33-20. In short, each two-purpose signal line 19 short-circuits in parallel the dielectric elements 35 of the respective electrode units 33 in the same column group and the signal terminals 34-2 of the respective temperature sensors 34 and is used to connect to an external device. It should be noted that these two-purpose signal lines 19 can selectively transmit alternating current signals or receive temperature detection signals, which can be achieved by respectively connecting each two-purpose signal line 19 in series with a two-way switch 55 and cooperating with the closing or opening of the ground wire 18, which will be described in detail below.
[0137] The multi-path ground wires 18 and the multi-path dual-purpose signal wires 19 are both conductive traces embedded in the flexible circuit board 31. The flexible circuit board 31 is electrically connected to the first cable 15. The multi-path ground wires 18 and the multi-path dual-purpose signal wires 19 embedded in the flexible circuit board 31 are respectively and electrically connected to the corresponding wires (not shown) in the first cable 15 one by one.
[0138] The tumor electric field therapy system 100 of this embodiment includes at least a pair of the above-mentioned electrode plates 13, a adapter 20 electrically connected to the electrode plates 13, and an electric field generator 30 electrically connected to the adapter 20. The adapter 20 is connected between the electrode plates 13 and the electric field generator 30. The electric field generator 30 provides an alternating current signal to the dielectric elements 35 in the multiple electrode units 33 of the electrode plates 13 or is used to receive the temperature detection signals output by the temperature sensors 34 in the multiple electrode units 33 via the dual-purpose signal wires 19 of the adapter 20 and the electrode plates 13. The adapter 20 transmits the alternating current signal generated by the electric field generator 30 to the dual-purpose signal wires 19 of the electrode plates 13, and is also configured to receive the temperature detection signals output by the multi-path dual-purpose signal wires 19 of the electrode plates 13.
[0139] Reference Figure 3 And Figure 4As shown, the adapter 20 includes: a first controller 51, multiple groups of analog-to-digital converters 52 connected to the first controller 51, multiple groups of voltage-dividing resistors 53 and multiple groups of grounding switches 54 corresponding to the multiple groups of analog-to-digital converters 52 one by one, multiple groups of bidirectional switching switches 55 connected to the multiple groups of analog-to-digital converters 52 one by one, a first communication unit 56, AC signal lines 57 corresponding to each group of bidirectional switching switches 55 one by one, and a first power module 58 connected to the first communication unit 56, the first controller 51, and the multiple groups of analog-to-digital converters 52 at the same time. The first power module 58 provides a DC power supply VCC for each electronic component of the adapter 20. The adapter 20 also includes multiple circuit lines (not labeled). Among them, the multiple circuit lines (not labeled) are respectively electrically connected to multiple ground wires 18 and multiple dual-purpose signal lines 19 in the flexible circuit board 31 of the corresponding electrode piece 13 through the first cable 15 of the corresponding electrode piece 13 one by one. The multiple circuit lines (not labeled) include multiple AC signal lines 57 that respectively transmit AC signal to the corresponding electrode piece 13 and are electrically connected to the multiple dual-purpose signal lines 19 in the flexible circuit board 31 of the corresponding electrode piece 3, multiple circuit lines (not labeled) that are respectively electrically connected to the multiple dual-purpose signal lines 19 in the flexible circuit board 31 of the corresponding electrode piece 13 one by one and are used to supply power to each temperature sensor 34 of the electrode piece 13 or transmit the temperature detection signal of the electrode piece 13, and multiple circuit lines (not labeled) that are respectively electrically connected to the multiple ground wires 18 in the flexible circuit board 31 of the corresponding electrode piece 13 one by one. The number L of circuit lines of the adapter 20 electrically connected to an electrode piece 13 is equal to the sum of the number of rows and columns of the electrode unit 33 of the electrode piece 13 plus one; the number H of circuit lines of the adapter 20 electrically connected to X electrode pieces 13 is equal to X times the number of circuit lines of it electrically connected to a single electrode piece 13, that is, H = XL = X*(M + N + 1). The number of groups of the grounding switches 54 and the number of groups of the bidirectional switching switches 55 are both related to the number of electrode pieces 13. The number of groups of the grounding switches 54 is the same as the number of groups of the bidirectional switching switches 55; and is not less than the number of electrode pieces 13. Preferably, the number of groups of the grounding switches 54 and the bidirectional switching switches 55 are both the same as the number of electrode pieces 13. The following takes the electrical connection between an electrode piece 13 with 20 electrode units 33 and the adapter 20 as an example for detailed description.
[0140] Each set of grounding switches 54 is provided with a plurality of grounding switches 54. The plurality of grounding switches 54 are respectively connected into the adapter 20 and are respectively electrically connected to circuit lines (not labeled) corresponding to the multiple ground wires 18 of a corresponding one of the electrode plates 13, and are configured to control the conduction or disconnection of the multiple ground wires 18. The circuit lines (not labeled) of the multiple ground wires 18 that are respectively and electrically connected to the electrode plate 13 are grounded at one end close to the grounding switch 54. The number of grounding switches 54 in each set of grounding switches 54 is related to the number of ground wires 18 of the flexible circuit board 31 of the corresponding electrode plate 13. In this embodiment, the two are equal. As Figure 3 or Figure 4 shown, in this embodiment, the plurality of grounding switches 54 are respectively a first grounding switch 54-1, a second grounding switch 54-2, a third grounding switch 54-3, and a fourth grounding switch 54-4. The multiple grounding switches 54 in the same group respectively control the closing or opening of the corresponding ground wires 18 of the same electrode plate 13. The first grounding switch 54-1 is used to control the closing or opening of the first ground wire 18-1 of the corresponding electrode plate 13, and thus can cooperate with the corresponding group of bidirectional switching switches 55 to control the power-on and power-off of the temperature sensors 34 of the five electrode units 33 from the electrode unit 33-1 to the electrode unit 33-5 in the first row group 33 of the electrode plate 13; the second grounding switch 54-2 is used to control the closing or opening of the second ground wire 18-2 of the electrode plate 13, and thus can cooperate with the corresponding group of bidirectional switching switches 55 to control the power-on and power-off of the temperature sensors 34 of the five electrode units 33 from the electrode unit 33-6 to the electrode unit 33-10 in the second row group 33 of the electrode plate 13; the third grounding switch 54-3 is used to control the closing or opening of the third ground wire 18-3 of the electrode plate 13, and thus can cooperate with the corresponding group of bidirectional switching switches 55 to control the power-on and power-off of the temperature sensors 34 of the five electrode units 33 from the electrode unit 33-11 to the electrode unit 33-15 in the third row group 33 of the electrode plate 13; the fourth grounding switch 54-4 is used to control the closing or opening of the fourth ground wire 18-4 of the electrode plate 13, and thus can cooperate with the corresponding group of bidirectional switching switches 55 to control the power-on and power-off of the temperature sensors 34 of the five electrode units 33 from the electrode unit 33-16 to the electrode unit 33-20 in the fourth row group 33 of the electrode plate 13. The above-mentioned grounding switch 54 can be a mechanical switch, such as a relay. The grounding switch 54 can also be an electronic switch, and each grounding switch 54 can be opened and closed through an additional first controller.
[0141] In this embodiment, multiple groups of grounding switches 54 are all electronic switches. The first controller 51 is communicatively connected to the multiple groups of grounding switches 54 and is configured to sequentially and cyclically control the opening and closing states of multiple grounding switches 54 in each group of grounding switches 54, thereby sequentially and individually conducting each of the multiple ground wires 18 of the corresponding electrode plate 13 and cooperating with the switching of the corresponding bidirectional switching switch 55 to continuously and real-time collect the temperature of the patient's body surface detected by all the temperature sensors 34 on the electrode plate 13. The number of grounding switches 54 in each group is not less than the number of ground wires 18 of the flexible circuit board 31 of the corresponding electrode plate 13. In this embodiment, the number of grounding switches 54 in each group is the same as the number of ground wires 18 of the corresponding electrode plate 13.
[0142] Each group of bidirectional switching switches 55 is provided with multiple bidirectional switching switches 55. The multiple bidirectional switching switches 55 in each group are respectively connected into the adapter 20 and are respectively electrically connected to circuit lines (not labeled) corresponding to the multiple multi-purpose signal lines 19 of a corresponding electrode plate 13 one by one. The number of bidirectional switching switches 55 in each group of bidirectional switching switches 55 is related to the number of multi-purpose signal lines 19 of the flexible circuit board 31 of the corresponding electrode plate 13, and is greater than or equal to the number of multi-purpose signal lines 19 of the flexible circuit board 31 of the corresponding electrode plate 13. In this embodiment, the two are equal. Each bidirectional switching switch 55 has two ends labeled 1 and 2. The 1 ends of the multiple bidirectional switching switches 55 in the same group are respectively electrically connected to the corresponding detection channels of the multiple detection channels of a corresponding group of analog-to-digital converters 52 one by one. The 2 ends of each bidirectional switching switch 55 in the same group are electrically connected to the corresponding same AC signal line 57 and are configured to control the multi-purpose signal line 19 to be connected to the corresponding AC signal line 57 to transmit an alternating current signal or to be connected to the corresponding detection channel of the corresponding group of analog-to-digital converters 52 to receive the temperature detection signal output by the temperature sensor 34.

The electric field generator 30 is also configured to control and adjust the voltage of the alternating current signal provided to the multiple electrode units 33 of the electrode plate 13 according to the received digital signals. Exemplarily, when any one of the received multiple digital signals exceeds a preset threshold, it means that the temperature detected by at least one dielectric element 35 in the electrode plate 13 exceeds the preset threshold temperature (such as 41°C, 42°C, etc.). At this time, the voltage of the alternating current signal output by the electric field generator 30 can be appropriately reduced to avoid the temperature of the electrode unit 33 of the electrode plate 13 being too high when applying the alternating current signal, causing low-temperature burns to the patient's skin.

[0150] The working principle of the tumor electric field treatment system 100 of this embodiment will be introduced in detail below with reference to Figures 3 to 5 the following.
[0151] Specifically, when it is necessary to detect the temperatures of the electrode units 33 of a certain electrode sheet 13, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 controls each of the plurality of two-way switches 55 in a group of two-way switches 55 electrically connected to the electrode sheet 13 to conduct at the 1-end and disconnect at the 2-end, so as to disconnect the alternating current signal applied to the electrode sheet 13; at the same time, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 controls each of the grounding switches 54 in a group of grounding switches 54 electrically connected to the electrode sheet 13 to conduct sequentially and time-divisionally. At this time, the temperature detection signals collected by the temperature sensors 34 of each electrode unit 33 in each row group of the electrode sheet 13 can be collected sequentially and time-divisionally through the plurality of detection channels A, B, C, D, and E of a group of analog-to-digital converters 52 corresponding to the electrode sheet 13. Each of the detection channels A, B, C, D, and E of each group of analog-to-digital converters 52 only collects the temperature detection signals of the temperature sensors 34 of the corresponding electrode units 33 among the electrode units 33 in the same row group of the electrode sheet 13 at the same time. The above temperature detection signals can be characterized by voltage values. Only 1 of the 4 grounding switches 54 in a group of grounding switches 54 corresponding to the electrode sheet 13 can conduct at the same moment, and the other 3 are disconnected. The 5 two-way switches 55 in a group of two-way switches 55 corresponding to the group of analog-to-digital converters 52 are all switched to their respective 1-ends so that the various two-way signal lines 19 of the electrode sheet 13 are electrically connected to the corresponding detection channels A, B, C, D, and E of the corresponding analog-to-digital converters 52 one by one and conduct.

The signal terminals 34-2 of the temperature sensors 34 of the electrode units 33-1, 33-6, 33-11 and 33-16 are short-circuited on the first detection channel A of the group of analog-to-digital converters 52. Since only the grounding terminal 34-1 of the temperature sensor 34 of the electrode unit 33-11 is conductively grounded, and the grounding terminals 34-1 of the temperature sensors 34 of the electrode units 33-1, 33-6 and 33-16 are all open, and a diode 36 is provided in series with the temperature sensor 34 on each electrode unit 33, the resistance value of the temperature sensor 34 of the electrode unit 33-11 is not affected. Therefore, only the temperature sensor 34 of the electrode unit 33-11 operates effectively on the first detection channel A of the group of analog-to-digital converters 52.

The voltage value collected on the fifth detection channel E of the group of analog-to-digital converters 52 is the voltage value of the temperature sensor 34 of the electrode unit 33-15.
[0155] When the grounding switch 54-4 is closed, the grounding switches 54-1, 54-2 and 54-3 are all open, and the first double-way switch 55-1, the second double-way switch 55-2, the third double-way switch 55-3, the fourth double-way switch 55-4 and the fifth double-way switch 55-5 are all switched to their respective terminal 1, the temperature sensors 34 of the electrode units 33-16 to 33-20 in the fourth row group are powered on, and the temperature sensors 34 of the electrode units 33-1 to 33-15 in the remaining row groups are powered off. The signal terminals 34-2 of the temperature sensors 34 of the electrode units 33-1, 33-6, 33-11 and 33-16 are short-circuited on the first detection channel A in the group of analog-to-digital converters 52. Since only the grounding terminal 34-1 of the temperature sensor 34 of the electrode unit 33-16 is conductively grounded, and the grounding terminals 34-1 of the temperature sensors 34 of the electrode units 33-1, 33-6 and 33-11 are all open, and a diode 36 is provided in series with the temperature sensor 34 on each electrode unit 33, the resistance value of the temperature sensor 34 of the electrode unit 33-16 will not be affected. Therefore, only the temperature sensor 34 of the electrode unit 33-16 operates effectively on the first detection channel A of the group of analog-to-digital converters 52. At this time, the temperature detection signal (voltage value) collected on the first detection channel A is the voltage value of the temperature sensor 34 of the electrode unit 33-16. Similarly, the voltage value collected on the second detection channel B in the group of analog-to-digital converters 52 is the voltage value of the temperature sensor 34 of the electrode unit 33-17. The voltage value collected on the third detection channel C in the group of analog-to-digital converters 52 is the voltage value of the temperature sensor 34 of the electrode unit 33-18. The voltage value collected on the fourth detection channel D in the group of analog-to-digital converters 52 is the voltage value of the temperature sensor 34 of the electrode unit 33-19. The voltage value collected on the fifth detection channel E in the group of analog-to-digital converters 52 is the voltage value of the temperature sensor 34 of the electrode unit 33-20. Thus, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 can collect the temperature detection signals of the temperature sensors 34 of all the electrode units 33 of a certain electrode plate 13 by controlling a group of double-way switches 55 and a group of grounding switches 54 that are all electrically connected to the electrode plate 13. Similarly, the temperature detection signals of the temperature sensors 34 of the electrode units 33 of other electrode plates 13 can be obtained.
[0156] The first controller 51, multiple groups of analog-to-digital converters 52, and multiple groups of bidirectional switches 55 can automatically perform operations through pre-programmed program codes. For example, the first controller 51 first controls all the bidirectional switches 55 in the corresponding group of bidirectional switches 55 to be switched to the 1 end, so that the 1 ends of these bidirectional switches 55 are all turned on and the 2 ends are all turned off, so that each dual-purpose signal line 19 of the corresponding electrode plate 13 is electrically connected to the corresponding group of analog-to-digital converters 52. Then, the grounding switch 54-1 in the corresponding group of grounding switches 54 is closed, and the remaining grounding switches 54-2 to 54-4 in this group of grounding switches 54 are opened. During this period, each detection channel A, B, C, D, and E of the analog-to-digital converter 52 in this group obtains the temperature detection signals of the temperature sensors 34 of each electrode unit 33 located in the first row group of the corresponding electrode plate 13, converts them into digital signals, and stores them in a separately provided memory. Then, after a preset time interval, the first controller 51 closes the grounding switch 54-2 in this group of grounding switches 54, and opens the grounding switch 54-1, the grounding switch 54-3, and the grounding switch 54-4 in this group of grounding switches 54. During this period, each detection channel A, B, C, D, and E of the analog-to-digital converter 52 in this group obtains the temperature detection signals of the temperature sensors 34 of each electrode unit 33 located in the second row group. By sequentially and separately turning on each grounding switch 54 in this group of grounding switches 54 in this way, the temperature detection signals of all the temperature sensors 34 on the electrode plate 13 can be obtained. Similarly, the temperature detection signals of all the temperature sensors 34 on at least a pair of electrode plates 13 can be obtained through this kind of operation.
[0157] The tumor electrotherapy system 100 of the present application can achieve real-time and comprehensive monitoring of the temperatures of all electrode units 33 on the electrode patch 13 without increasing the weight of the electrode patch 13 and without increasing the cores of the first cables 15 electrically connected to the electrode patch 13. Furthermore, it can judge whether the electrode patch 13 is qualified based on the obtained temperature detection signal; or it can judge whether there are faults or abnormalities in the temperature sensors 34 of the electrode patch 13 based on the obtained temperature detection signal, and judge whether the electrode patch 13 needs to be replaced based on the number of temperature sensors 34 with faults or abnormalities; or it can identify the type of the electrode patch based on the obtained temperature detection signal when the electrode patch is qualified; or it can judge whether there is overheating in the electrode units 33 of the electrode patch 13 based on the obtained temperature detection signal when the electrode patch is qualified, and then control the alternating current signal applied to the electrode patch 13 or the corresponding column electrode units 33 of the electrode patch 13 to avoid low-temperature burns on the patient's body surface during tumor treatment through the electrode patch 13. In addition, the flexible circuit board 31 of the electrode patch 13 of the present application electrically connects the dielectric element 35 of the same electrode unit 33 and the signal terminal 34-2 of the temperature sensor 34 through the same dual-purpose signal line 19 arranged thereon. While it can transmit both alternating current signals and direct current signals for temperature signal acquisition and the acquired temperature detection signals through the dual-purpose signal line 19, it also greatly reduces the number of conductive traces (ground wire 18, dual-purpose signal line 19) arranged thereon, reduces the wiring difficulty of the flexible circuit board 31, simplifies the manufacturing process, reduces the weight of the flexible circuit board 31, and reduces the manufacturing cost. The electrode patch 13 of the present application can also be switched between applying an alternating current signal for tumor treatment and transmitting a direct current signal for temperature acquisition and transmitting the acquired temperature detection signal through the combined control of a ground switch 54 electrically connected to the ground wire 18 arranged thereon and a bidirectional switch 55 electrically connected to the dual-purpose signal line 19.
[0158] When an alternating current signal needs to be applied to the patient through each electrode unit 33 of a certain electrode patch 13, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 controls to disconnect all the grounding switches 54 in a group of grounding switches 54 corresponding to the electrode patch 13, and at the same time controls to switch all the two-way switches 55 in a group of two-way switches 55 corresponding to the electrode patch 13 to their 2 ends respectively, so that the 1 ends of these two-way switches 55 are all disconnected and the 2 ends are all conducted, realizing that each two-purpose signal line 19 of the electrode patch 13 is electrically connected to an AC signal line 57 corresponding to the adapter 20 and the electrode patch 13, thereby transmitting the alternating current signal to each electrode unit 33 of the electrode patch 13.When the temperature detection signals of the temperature sensors 34 of all electrode units 33 of the detected electrode plate 13 are much lower than the preset temperature threshold stored in the electric field generator 20 or the adapter 20, the electric field generator 30 controls the AC signal generator 39 to continue generating an alternating current signal with an increasing voltage or current amplitude or an unchanged voltage or current amplitude through its second controller 37, and then transmits it to the corresponding pair of electrode plates 13 through a corresponding AC signal line 57 of the adapter 20, so as to continue applying the alternating current signal to the pair of electrode plates 13; when the temperature detection signals of the temperature sensors 34 of all electrode units 33 of the detected electrode plate 13 are lower than but close to the preset temperature threshold stored in the electric field generator 30 or the adapter 20, the electric field generator 30 can reduce the voltage or current of the alternating current signal generated by the AC signal generator 39 through the second controller 37, and then reduce the voltage or current of the alternating current signal applied to the pair of electrode plates 13; when the temperature detection signal of the temperature sensor 34 of an electrode unit 33 of a certain electrode plate 13 is detected to be greater than the preset temperature threshold, the electric field generator 30 controls the AC signal switch 40 electrically connected to the electrode plate 13 to disconnect through the second controller 37, so as to stop applying the alternating current signal to the electrode plate 13; or the second controller 37 of the electric field generator 30 or the first controller 21 of the adapter 20 controls all the bidirectional switches 55 in a group of bidirectional switches 55 electrically connected to the electrode plate 13 to switch from their 2 ends to their 1 ends, that is, controls all the 1 ends of the group of bidirectional switches 55 electrically connected to the electrode plate 13 to be conducted and all the 2 ends to be disconnected, so as to stop applying the alternating current signal to the electrode plate 13; or, when the temperature detection signal of the temperature sensor 34 of an electrode unit 33 of a certain electrode plate 13 is detected to be greater than the preset temperature threshold, the second controller 37 of the electric field generator 30 controls the AC signal switch electrically connected to the electrode plate 13 to continue to conduct, and the second controller 37 of the electric field generator 30 or the first controller 21 of the adapter 20 controls a bidirectional switch 55 electrically connected to the electrode unit 33 of the electrode plate 13 to switch from its 2 end to its 1 end, and at the same time, the second controller 37 of the electric field generator 30 or the first controller 21 of the adapter 20 controls the remaining bidirectional switches 55 electrically connected to the electrode units 33 whose temperature detection signals do not exceed the preset temperature threshold and are in different columns from the electrode units 33 with temperature detection signals exceeding the preset temperature threshold of the electrode plate 13 to continue to be electrically connected to their respective 2 ends, so as to stop applying the alternating current signal to all the electrode units 33 in the column where the electrode unit 33 with the temperature detection signal exceeding the preset temperature threshold of the electrode plate 13 is located, and continue to apply the alternating current signal to the remaining column electrode units 33 of the electrode plate 13 whose temperature detection signals do not exceed the preset temperature threshold. Thus, an alternating current signal application control method of the tumor electric field treatment system 100 based on the temperature detection signal is realized.
[0159] In the embodiments of the present application, the grounding switch 54 electrically connected to each of the multiple ground wires 18 of the electrode sheet 13 and the bidirectional switching switch 55 electrically connected to each of the multiple dual-purpose signal lines 19 of the electrode sheet 13 are both provided in the adapter 20. However, in other embodiments, the grounding switch 54 electrically connected to the ground wire 18 and the bidirectional switching switch 55 electrically connected to the dual-purpose signal line 19 may also be provided on the electrode sheet 13 or in the electric field generator 30, which will not be elaborated herein. In addition, the analog-to-digital converter 52 provided in the adapter 20 may also be provided in the electric field generator 30 and directly controlled by the second controller 37.
[0160] An electrode sheet temperature detection method is provided in an embodiment of the present application, which is applied to the above-mentioned electrode sheet 13 or the tumor electric field treatment system 100. Refer Figure 8 as shown, it includes the following steps:
[0161] Step 210: Control the bidirectional switching switch 55 electrically connected to each electrode unit 33 of the electrode sheet 13 to disconnect the alternating current signal applied to the dielectric element 35 of each electrode unit 33 of the electrode sheet 13 and simultaneously connect the direct current signal applied to the signal terminal 34-2 of the temperature sensor 34 of each electrode unit 33 of the electrode sheet 13.
[0162] Step 220: Sequentially conduct the grounding switch 54 electrically connected to the grounding terminal 34-1 of the temperature sensor 34 of each electrode unit 33 of the electrode sheet 13 to obtain the temperature detection signal of the temperature sensor 34 of each electrode unit 33 of the electrode sheet 13.
[0163] Step 210 is specifically: Control the bidirectional switching switch 55 electrically connected to each electrode unit 33 of the electrode sheet 13 to switch from the end electrically connected to the alternating current signal to the end electrically connected to the direct current signal, that is, control the bidirectional switching switch 55 electrically connected to the electrode sheet 13 to switch from its end 2 to its end 1; or
[0164] Control the bidirectional switching switch 55 electrically connected to each electrode unit 33 of the electrode sheet 13 to switch the dielectric element 35 of each electrode unit 33 of the electrode sheet 13 from the conducting state to the disconnected state and simultaneously switch the signal terminal 34-2 of the temperature sensor 34 of each electrode unit 33 of the electrode sheet 13 from the disconnected state to the conducting state.
[0165] By using the electrode sheet temperature detection method of the present application, the temperatures of all electrode units of the electrode sheet can be obtained quickly and accurately; and based on the temperature detection signals of all temperature sensors of the obtained electrode sheet, it can be judged whether there is a fault or an abnormality in the temperature sensors of the electrode sheet, whether the electrode sheet is qualified, or whether it needs to be replaced; it can also judge whether there is overheating in each electrode unit of the electrode sheet based on the temperature detection signals of all temperature sensors of the obtained electrode sheet when the temperature sensors of the electrode sheet are normal, and then control the alternating current signal applied to the electrode sheet or each electrode unit of the electrode sheet; it can also identify the type of the electrode sheet when the temperature detection signals of the temperature sensors of the electrode sheet are normal.
[0166] As shown Figure 9 in FIG. [not shown in the original, assumed to be a figure reference], an embodiment of the present application further provides an electrode sheet qualification detection method, which includes the above steps 210 and 220, and after step 220, it further includes:
[0167] Step 221: Judge whether there is an abnormality or a fault in the temperature sensors 34 of each electrode unit 33 of the electrode sheet 13 according to the temperature detection signals of the temperature sensors 34 of each electrode unit 33 of the obtained electrode sheet 13;
[0168] Step 222: Judge whether the electrode sheet is qualified according to whether there is an abnormality or a fault in the temperature sensor 34 of the electrode sheet 13.
[0169] Judging whether the electrode sheet is qualified in step 222 further includes the following steps:
[0170] When there is an abnormality or a fault in the temperature sensors 34 of each electrode unit 33 of the electrode sheet 13, it is determined that the electrode sheet is unqualified; or
[0171] When there is no abnormality or fault in the temperature sensors 34 of each electrode unit 33 of the electrode sheet 13, it is determined that the electrode sheet is qualified.
[0172] As shown Figure 10 in FIG. [not shown in the original, assumed to be a figure reference], an embodiment of the present application further provides an electrode sheet replacement detection method: it includes the above steps 210 and 220, and after step 220, it further includes:
[0173] Step 230: Judge whether there is an abnormality or a fault in the temperature sensors 34 of each electrode unit 33 of the electrode sheet 13 according to the temperature detection signals of the temperature sensors 34 of each electrode unit 33 of the obtained electrode sheet 13;
[0174] Step 240: Judge whether the electrode sheet needs to be replaced according to whether there is an abnormality or a fault in the temperature sensor 34 of the electrode sheet 13.
[0175] The determination of whether the electrode sheet needs to be replaced in step 240 further includes the following steps:
[0176] When there are abnormalities or malfunctions in the temperature sensors 34 of the electrode sheet 13 and the number of temperature sensors 34 with abnormalities or malfunctions exceeds a preset threshold, it is determined that the electrode sheet needs to be replaced; or
[0177] When the number of temperature sensors 34 with abnormalities or malfunctions in the electrode sheet 13 does not exceed the preset threshold, it is determined that the electrode sheet does not need to be replaced.
[0178] The preset threshold is 20% of the total number of all temperature sensors of the electrode sheet.
[0179] See Figure 11 As shown, the present application also provides a method for detecting abnormal temperature of an electrode sheet. This method includes the above steps 210 and 220, and further includes, after step 220:
[0180] Step 250: Perform temperature anomaly detection at each electrode unit 33 of the electrode sheet 13 according to the temperature detection signals of the temperature sensors 34 of each electrode unit 33 of the obtained electrode sheet 13.
[0181] The temperature anomaly detection of each electrode unit 33 of the electrode sheet 13 in step 250 specifically includes the following steps:
[0182] Step 251: Compare the obtained temperature detection signals of each electrode unit 33 of the electrode sheet 13 with a preset temperature threshold;
[0183] Step 252: Determine whether there is a temperature anomaly in each electrode unit 33 of the electrode sheet according to the comparison result.
[0184] The comparison results in step 252 include not exceeding the preset temperature threshold and exceeding the preset temperature threshold. Not exceeding the preset temperature threshold includes being far lower than the preset temperature threshold and being close to the preset temperature threshold. The preset temperature threshold is 40°C - 42°C. Preferably, the preset temperature threshold is 40.5°C - 41.5°C. Preferably, the preset temperature threshold is 41°C - 41.5°C. Preferably, the preset temperature threshold is 41°C.
[0185] The process of determining whether there is a temperature anomaly in each electrode unit 33 of the electrode sheet 13 in step 252 is specifically as follows:
[0186] Step 253: When the obtained temperature detection signal does not exceed the preset temperature threshold, it is determined that the electrode sheet 13 does not have a temperature anomaly; or
[0187] Step 254: When the obtained temperature detection signal exceeds the preset temperature threshold, it is determined that the electrode sheet 13 has a temperature anomaly.
[0188] SeeFigure 12 As shown, an embodiment of the present application further provides a control method for applying an alternating current signal for tumor electrotherapy, which includes the above-mentioned steps 210 and 220, and after step 220, further includes:
[0189] Step 260: When it is determined that the electrode patch does not need to be replaced, control or adjust the alternating current signal applied to each electrode unit 33 of the electrode patch 13 according to the temperature detection signals of the temperature sensors 34 of each electrode unit 33 of the electrode patch 13 obtained.
[0190] The control method for applying an alternating current signal for tumor electrotherapy according to the embodiment of the present application may further include the above-mentioned steps 230 and 240 between step 220 and step 260.
[0191] The control method for applying an alternating current signal for tumor electrotherapy according to the embodiment of the present application may further include step 250 between step 240 and step 260.
[0192] Controlling or adjusting the alternating current signal applied to each electrode unit 33 of the electrode patch 13 in step 260 further includes:
[0193] Step 261: When the temperature detection signals of each electrode unit 33 of the electrode patch 13 obtained do not exceed the preset temperature threshold, continue to apply the alternating current signal to each electrode unit 33 of the electrode patch 13; or
[0194] Step 262: When there is a temperature detection signal exceeding the preset temperature threshold among the temperature detection signals of all electrode units 33 of the electrode patch 13 obtained, stop applying the alternating current signal to the electrode units 33 of the electrode patch 13.
[0195] The stopping of applying the alternating current signal to the electrode units 33 of the electrode patch 13 in step 262 includes stopping applying the alternating current signal to all electrode units 33 of the electrode patch 13, stopping applying the alternating current signal to the electrode units 33 of the electrode patch 13 whose temperature detection signals exceed the preset temperature threshold, and stopping applying the alternating current signal to all electrode units 33 in the column where the electrode units 33 of the electrode patch 13 whose temperature detection signals exceed the preset temperature threshold are located.
[0196] When stopping applying the alternating current signal to the electrode units 33 of the electrode patch 13 whose temperature detection signals exceed the preset temperature threshold, the electrode units 33 of the electrode patch 13 whose temperature detection signals do not exceed the preset temperature threshold continue to be applied with the alternating current signal.
[0197] When the application of the alternating current signal to all the electrode units 33 in the column where the electrode unit 33 with a temperature detection signal exceeding the preset temperature threshold in the electrode sheet 13 is stopped, all the electrode units 33 in the electrode sheet 13 with a temperature detection signal not exceeding the preset temperature threshold and in a different column from the electrode unit 33 with a temperature detection signal exceeding the preset temperature threshold continue to be applied with the alternating current signal.
[0198] The process of continuing to apply the alternating current signal to the electrode sheet 13 described in step 261 is specifically as follows:
[0199] Step 263: When the temperature detection signal is much lower than the preset temperature threshold, continue to apply the alternating current signal to each electrode unit 33 of the electrode sheet 13 by increasing the voltage or current amplitude of the alternating current signal applied to each electrode unit 33 of the electrode sheet 13 or by keeping the voltage or current amplitude of the alternating current signal applied to each electrode unit 33 of the electrode sheet 13 unchanged; or
[0200] Step 264: When the temperature detection signal is close to the preset temperature threshold, continue to apply the alternating current signal to each electrode unit 33 of the electrode sheet 13 by keeping the voltage or current amplitude of the alternating current signal applied to each electrode unit 33 of the electrode sheet 13 unchanged or by reducing the voltage or current amplitude of the alternating current signal applied to each electrode unit 33 of the electrode sheet 13.
[0201] Refer Figure 13 As shown, the embodiment of the present application further provides a method for identifying the type of electrode sheet, which includes the above steps 210 and 220, and after step 220 when the electrode sheet 13 is qualified or each temperature sensor 34 of the electrode sheet 13 has no abnormality or failure, it further includes:
[0202] Step 270: Perform type identification of the electrode sheet 13 according to the temperature detection signals of the temperature sensors 34 of each electrode unit 33 of the electrode sheet 13 obtained.
[0203] The present application further provides a signal control method for tumor electric field therapy, which is used for the above-mentioned tumor electric field therapy system 100 or for the above-mentioned electrode sheet 13. This method includes: performing combined control on the grounding switch 54 and the bidirectional switching switch 55 electrically connected to the electrode sheet 13 to enable each electrode unit 33 of the electrode sheet 13 to switch between applying the alternating current signal and collecting the temperature detection signal.
[0204] Refer Figure 14 As shown, the present application further provides a signal control method for tumor electric field therapy, which is used for the above-mentioned electrode sheet 13. This method includes:
[0205] Step 310: Combine and control the grounding switch 54 and the bidirectional switch 55 electrically connected to the corresponding electrode sheet 13 to apply an alternating current signal to each electrode unit 33 of the electrode sheet 13 and execute Step 320;
[0206] Step 320: Combine and control the grounding switch 54 and the bidirectional switch 55 electrically connected to the electrode sheet 13 to collect the temperature detection signals of each electrode unit of the electrode sheet 13 row by row and execute Step 330;
[0207] Step 330: Determine the combined control mode of the grounding switch 54 and the bidirectional switch 55 electrically connected to the electrode sheet 13 according to the collected temperature detection signals and execute Step 340;
[0208] Step 340: Control the working states of each electrode unit 33 of the electrode sheet 13 according to the determined combined control mode of the grounding switch 54 and the bidirectional switch 55.
[0209] The working states of each electrode unit 33 of the electrode sheet 13 described in Step 340 include at least one of: stopping applying the alternating current signal and continuing to collect the temperature detection signals, and stopping collecting the temperature detection signals and continuing to apply the alternating current signal. Continuing to apply the alternating current signal includes continuing to apply the alternating current signal in a manner of increasing the voltage or current amplitude of the currently applied alternating current signal, continuing to apply the alternating current signal in a manner of keeping the voltage or current amplitude of the currently applied alternating current signal unchanged, and continuing to apply the alternating current signal in a manner of decreasing the voltage or current amplitude of the currently applied alternating current signal.
[0210] The working states of each electrode unit 33 of the electrode sheet 13 are determined by the temperature detection signals collected by it. Each electrode unit 33 of the electrode sheet 13 is divided into different regions, and through the combined control of the grounding switch 54 and the bidirectional switch 55, each electrode unit 33 in each region can cycle between applying the alternating current signal and collecting the temperature detection signals.
[0211] The embodiment of the present application provides another electrode sheet temperature detection method 500 for the tumor electric field treatment system 100. Please refer to Figure 15 as shown. This temperature detection method 500 includes:
[0212] Step 510: Disconnect the input of the alternating current signal of the electrode sheet 13, combine and control a plurality of grounding switches 54 and a plurality of bidirectional switches 55, and obtain the temperature detection signals of the temperature sensors 34 of the electrode sheet 13 corresponding to each combination in all combinations;
[0213] Step 520: Sample and convert the temperature detection signals detected by each temperature sensor 34 in the electrode sheet 13 to obtain digital temperature signals;
[0214] Step 530: Transmit the digital temperature signal to the electric field generator 30 of the tumor electric field therapy system 100, so that the electric field generator 30 determines the temperature at the corresponding electrode unit 33 according to the digital temperature signal.
[0215] In step 510, "combining and controlling multiple grounding switches 54 and multiple bidirectional switching switches 55" specifically includes:
[0216] Step 511: Place all the bidirectional switching switches 55 at the 1 end to conduct the electrical connection between the signal terminals 34-2 of the temperature sensors 34 of all electrode units 33 and the corresponding analog-to-digital converters 52;
[0217] Step 512: Sequentially and separately close one of the multiple grounding switches 54 at different times to collect the temperature detection signals detected by the temperature sensors 34 of the electrode units 33 in the corresponding row groups row by row.
[0218] Sequentially and separately closing one of the multiple grounding switches 54 at different times in step 512 can conduct the detection channels in which the analog-to-digital converter 52 is electrically connected to all the temperature sensors 34 in the row group corresponding to the closed grounding switch 54.
[0219] Thus, the temperature detection signals of the corresponding temperature sensors 34 in each row group can be obtained in sequence, and then, after being processed by the adapter 20 or the electric field generator 30, the temperatures corresponding to all the electrode units 33 on the electrode patch 13 can be obtained; thereby making the temperature detection on the patient's body surface more comprehensive and accurate.
[0220] For the tumor electric field therapy system 100 according to the embodiment of the present application, the temperature of a single electrode unit 33 can also be detected as needed. The specific process of the method for detecting the temperature of a certain electrode unit 33 on the electrode patch 13 is as follows: Disconnect the input of the alternating current signal, place the bidirectional switching switch 55 corresponding to the column group where the electrode unit 33 to be separately temperature-measured is located at the 1 end, and place the remaining bidirectional switching switches 55 at the 2 end; at the same time, conduct and ground the grounding switch 54 corresponding to the row group where the electrode unit 33 to be separately temperature-measured is located, and disconnect all the remaining grounding switches 54. Thus, the temperature detection signal of the temperature sensor 34 in the electrode unit 33 to be separately temperature-measured can be sampled to obtain the temperature of the electrode unit 33. For example, if the electrode unit 33 to be separately temperature-measured is the electrode unit 33-1, at this time, place the bidirectional switching switch 55-1 corresponding to the electrode unit 33-1 at the 1 end, and place all the remaining bidirectional switching switches (55-2 to 55-5) at the 2 end; at the same time, close and ground the grounding switch 18-1 corresponding to the electrode unit 33-1, and disconnect all the remaining grounding switches (18-2 to 18-4). Thus, the temperature of the electrode unit 33-1 can be detected.
[0221] Another method 600 for applying an alternating current signal for tumor electrotherapy is also provided in an embodiment of the present application, which is applied to the above-mentioned tumor electrotherapy system 100. Please refer to Figure 16 As shown, the method 600 for applying an alternating current signal includes:
[0222] Step 610: Determine the area (1-5) where the electrode unit 33 that needs to apply an alternating current signal is located in the electrode sheet 13;
[0223] Step 611: Combine and control a plurality of grounding switches 54 and a plurality of bidirectional switching switches 55 electrically connected to the electrode sheet 13 to apply an alternating current signal.
[0224] In step 611, "combining and controlling a plurality of grounding switches 54 and a plurality of bidirectional switching switches 55 electrically connected to the electrode sheet 13" specifically means:
[0225] Step 612: Disconnect all the grounding switches 54 electrically connected to the electrode sheet 13;
[0226] Step 613: Determine the column groups where the electrode units 33 in the areas that need to apply an alternating current signal are located according to the area where the electrode unit 33 that needs to apply an alternating current signal is located;
