[0003] Currently, tumor electric field therapy systems mainly include an electric field generator, an adapter electrically connected to the electric field generator, and multiple pairs of electrode pads electrically connected to the electric field generator via the adapter. The electric field generator transmits an alternating electric signal for tumor electric field therapy to each electrode pad through the adapter, and then applies an alternating electric field to the tumor site of the patient through the electrode pads for tumor electric field therapy. Since the alternating electric field applied to the patient will accumulate heat at the corresponding position where the electrode pad is attached to the skin, in order to avoid low-temperature burns to the skin, a temperature sensor needs to be configured at each electrode unit to monitor the temperature of each electrode pad.Skin surface temperature at the electrode unit. However, during tumor treatment using electrode pads, it is inevitable that a very small number of electrode pads will experience individual temperature sensors malfunctioning after a period of use.

At least one pair of electrode pads 110 can be disposed in pairs on the patient's body surface, as shown in Figure 1 with four electrode pads 110, each pair of electrode pads 110 disposed on the patient's body surface. An electric field generator 130 is used to supply power to the at least one pair of electrode pads 110, thereby generating an alternating electric field for tumor treatment between the at least one pair of electrode pads 110. An adapter 120 is electrically connected between the at least one pair of electrode pads 110 and the electric field generator 130, for transmitting the alternating electrical signal generated by the electric field generator 130 to the at least one pair of electrode pads 110. That is, the electric field generator 130 can generate an alternating electrical signal, which is transmitted to each electrode pad 110 through the adapter 120, thereby generating an alternating electric field between the same pair of electrode pads 110.An alternating electric field is generated for treating tumors, so as to apply an alternating electric field to the tumor site of the patient for tumor treatment.

[0040] As shown in FIG1, in this embodiment, there are 4 electrode pads 110, each electrode pad 110 includes the same number of electrode units 112, each electrode unit 112 is electrically connected to the adapter 120, and the number of electrode units 112 on each electrode pad 110 is 20. In some embodiments, the tumor electric field therapy system 100 may have more or fewer electrode pads 110; in some embodiments, each pair of electrode pads 110 has the same number of electrode units 112, and different pairs of electrode pads 110 may have different numbers of electrode units 112; in some embodiments, the number of electrode units 112 on each electrode pad 110 may be 9, 13, 19, etc.

[0041] Figure 2 is a schematic diagram of the circuit connection between an electrode 110 and an adapter 120 of the tumor electric field therapy system 100 shown in Figure 1. It is worth noting that the arrangement of the electrode units 112 shown in Figure 2 is to more clearly show the electrical connection between an electrode 110 and the adapter 120. The arrangement of the electrode units 112 shown in Figure 2 does not represent the spatial arrangement of the electrode units 112. Combining Figures 1 and 2, the electrode 110 includes: a substrate 111, a plurality of electrode units 112 electrically connected to the substrate 111 at intervals, a plurality of temperature detection units 113, and a first cable 116 electrically connected to the substrate 111. The substrate 111 may be a flexible circuit board. The substrate 111 is embedded with multiple conductive traces, including multiple ground lines 118 and multiple dual-purpose signal lines 119. The first cable 116 has nine core wires (not shown), each of which is electrically connected to the multiple grounding wires 118 and the multiple dual-purpose signal lines 119 of the substrate 111. In this embodiment, the total number of grounding wires 118 and dual-purpose signal lines 119 embedded in the substrate 111 does not exceed nine, so the number of wires in the first cable 116 does not exceed nine.

[0042] Multiple electrode units 112 are configured into multiple row groups and multiple column groups. In this embodiment, each electrode sheet 110 has 20 electrode units 112. The 20 electrode units 112 are arranged in the order of 1 to 20 in the circuit connection and are divided into four row groups and five column groups, that is, the 20 electrode units 112 are arranged in four rows and five columns in the circuit connection. Each electrode unit 112 corresponds to a temperature detection unit 113, and each temperature detection unit 113 has a signal terminal 113B and a ground terminal 113A. Both electrode unit 112 and temperature detection unit 113 are soldered onto substrate 111. Electrode unit 112 is connected to the corresponding temperature detection unit 113.The signal terminal 113B of the temperature detection unit 113 is shorted. Since multiple temperature detection units 113 are configured one-to-one with multiple electrode units 112, the multiple temperature detection units 113 are also arranged in a four-row, five-column configuration in their circuit connections. It should be noted that this arrangement is for clearer illustration of the electrical connection between the electrode pad 110 and the adapter 120, and does not represent the spatial arrangement of the electrode units 112. Their spatial structure may be a roughly array-like structure as shown in Figure 1, or other structures such as petal-shaped or scattering structures; they can be regular or irregular. The electrode units 112 are configured to apply alternating signals to the patient's tumor site. The temperature detection units 113 are configured to detect the temperature of the patient's body surface where the electrode pad 110 is attached, i.e., the temperature at the corresponding electrode unit 112, and output a temperature detection signal to an external device such as the adapter 120. In this embodiment, the multi-purpose signal lines 119 of the substrate 111 are respectively configured to correspond one-to-one with multiple columns of electrode units 112, and are configured to transmit the alternating electrical signal generated by the electric field generator 130 to each electrode unit 112 in the corresponding column. That is, the electrode units 112 located in the same column are all short-circuited through the same multi-purpose signal line 119 of the substrate 111, and the electrode units 112 located in different columns are connected in parallel through different multi-purpose signal lines 119 of the substrate 111. The multi-purpose signal lines 119 of the substrate 111 are electrically connected to the first cable 116, and then electrically connected to the electric field generator 130 via the adapter 120. Further, the multi-purpose signal lines 119 of the substrate 111 receive the alternating electrical signal generated by the electric field generator 130 through the first cable 116 and the adapter 120.

[0043] Multiple grounding lines 118 are respectively configured to correspond one-to-one with multiple rows of electrode units 112. The multiple grounding lines 118 are used to sequentially short-circuit and ground each temperature detection unit 113 in each row group. That is, the grounding terminals 113A of multiple temperature detection units 113 located in the same row group are all short-circuited through the same grounding line 118 of the substrate 111, and the grounding terminals 113A of temperature detection units 113 located in different row groups are respectively connected in parallel through different grounding lines 118 of the substrate 111. During the time period of temperature detection, only one of the multiple grounding lines 118 is conducting at any given time, and the rest are disconnected.

[0044] Each of the multiplexed dual-purpose signal lines 119 is further configured to short-circuit the signal terminal 113B of at most one temperature detection unit 113 in each row group to an external device for receiving detection signals. The signal terminals 113B of the temperature detection units 113 connected to each of the multiplexed dual-purpose signal lines 119 are different to avoid subsequent repetitive signal outputs from the dual-purpose signal lines 119. That is, when the number of electrode units 112 in a row group is the same as the number of dual-purpose signal lines 119, each dual-purpose signal...Line 119 is electrically connected to the signal terminal 113B of a different temperature detection unit 113 in the same row group. When the number of electrode units 112 in a row group is less than the number of dual-purpose signal lines 119, at least one dual-purpose signal line 119 is not electrically connected to the signal terminal 113B of the temperature detection unit 113, and the remaining dual-purpose signal lines 119 are electrically connected to the signal terminal 113B of a different temperature detection unit 113 in the same row group. In this embodiment, the external device for receiving the detection signal is an adapter 120. The signal terminals 113B of multiple temperature detection units 113 located in different columns are connected in parallel through different dual-purpose signal lines 119 of the substrate 111, and the signal terminals 113B of multiple temperature detection units 113 located in the same column group are all short-circuited to the same dual-purpose signal line 119 of the substrate 111.

[0045] In this embodiment, with a temperature detection unit 113 configured in each electrode unit 112 for temperature detection, the above-described circuit design reduces the number of wires in the first cable 116, avoiding increased cable thickness and stiffness, which would increase the difficulty of cable fixation; simultaneously, it avoids the increased number of wires in the first cable 116 affecting the adhesion between the electrode pad 110 and the corresponding body surface of the patient's tumor site. The substrate 111 has a total of 9 embedded grounding wires 118 and dual-purpose signal lines 119. Specifically, in this embodiment, the substrate 111 has 4 embedded grounding wires 118 and 5 embedded dual-purpose signal lines 119. The number of grounding wires 118 is related to the number of rows M of the electrode unit 112, and is greater than or equal to the number of rows M, where M is a positive integer. The number of dual-purpose signal lines 119 is related to the number of columns N of the electrode unit 112, and is greater than or equal to the number of columns N, where N is a positive integer. The number of lines L embedded in the substrate 111 of the electrode sheet 110 is equal to the sum of the number of ground lines 118 and the number of dual-purpose signal lines 119. In this embodiment, the number of ground lines 118 is equal to the number of rows M of the electrode unit 112; the number of dual-purpose signal lines 119 is equal to the number of columns N of the electrode unit 112.

[0046] In terms of spatial structure, multiple electrode units 112 are arranged at intervals on the substrate 111 in a roughly two-dimensional array. As shown in Figure 1, the electrode sheet 110 in this embodiment includes 20 electrode units 112 and 20 temperature detection units 113 corresponding to the electrode units 112. The 20 electrode units 112 are arranged in an array of four rows and six columns. Each of the first and fourth rows has four electrode units 112, and each of the second and third rows has six electrode units 112. The four electrode units 112 in each of the first and fourth rows are located in the second to fifth columns, respectively, and the six electrode units 112 in each of the second and third rows are located in the first to sixth columns, respectively.

[0047] As shown in FIG1, in terms of spatial structure, multiple electrode units 112 are connected in an asymmetrical connection manner. For example, in the four electrode units 112 located in the first row and third column, the second row and third column, the third row and third column, and the fourth row and third column, adjacent electrode units 112 are connected by a column-direction connecting strip (unlabeled). At the same time, in the four electrode units 112 located in the first row and fifth column, the second row and fifth column, the third row and fifth column, and the fourth row and fifth column, adjacent electrode units 112 are also connected by a column-direction connecting strip (unlabeled). Each electrode sheet 110 has a free end. For example, at least one electrode unit 112 among the plurality of electrode units 112 is connected to at most one other electrode unit 112. For example, each electrode unit 112 located in the first row, second column, second row, first column, second row, second column, third row, first column, third row, and fourth row, second column has no connecting strips in its column direction, thereby forming an open space. This open space is adjustable; for example, the position of the electrode unit 112 in the first row, second column is movable relative to the position of the electrode unit 112 in the first row, third column. The positions of the electrode units 112 in the second row and first column are movable relative to those in the second row and second column, the positions of the electrode units 112 in the third row and first column are movable relative to those in the third row and second column, and the positions of the electrode units 112 in the fourth row and second column are movable relative to those in the fourth row and third column. Thus, when the electrode pad 110 is applied to the patient's body surface, the open space between the corresponding electrode units 112 can be adjusted by adjusting the positions of the electrode units 112 in the first row and second column, the second row and first column, the third row and first column, and the fourth row and second column. This increases the heat dissipation space of the corresponding electrode units 112, thereby accelerating heat dissipation. At the same time, it is beneficial for the patient to adjust the position of the electrode units 112 based on the fever or the skin condition of the area where the electrode pad 110 is applied. Similarly, the electrode units 112 located in the first row, fourth column, second row, fourth column, second row, sixth column, third row, and fourth row, fourth column also have no connecting strips in the column direction, thus forming an open space. This open space is adjustable. For example, the position of the electrode unit 112 in the first row, fourth column can be moved relative to the position of the electrode unit 112 in the first row, fifth column; the position of the electrode units 112 in the second row, fourth column and second row, sixth column can be moved relative to the position of the electrode unit 112 in the second row, sixth column and third row, sixth column and third row, sixth column and fourth row, fourth column and fourth column can be moved relative to the position of the electrode unit 112 in the fourth row, fifth column and fourth column. Thus, when the electrode pad 110 is applied to the patient's body surface, the position of the electrode unit 112 in the first row, fourth column, second row, sixth column and fourth column can be adjusted.The positions of the electrode units 112 in the first row, the sixth column of the second row, the sixth column of the third row, and the fourth column of the fourth row can be adjusted to increase the heat dissipation space of the corresponding electrode units 112, thereby accelerating heat dissipation. At the same time, it is beneficial for patients to adjust the position of the electrode units 112 based on the fever or the skin condition of the area where the electrode pad 110 is applied.

[0048] As shown in Figure 1, in terms of spatial structure, the four electrode units 112 located in the first row can be divided into region 1; the four electrode units 112 located in the first column of the second row, the first column of the third row, the second column of the fourth row, and the third column of the fourth row can be divided into region 2; the four electrode units 112 located in the sixth column of the second row, the sixth column of the third row, the fourth column of the fourth row, and the fifth column of the fourth row can be divided into region 3; the four electrode units 112 located in the second column of the second row, the third column of the second row, the second column of the third row, and the third column of the third row can be divided into region 4; and the four electrode units 112 located in the fourth column of the second row, the fifth column of the second row, the fourth column of the third row, and the fifth column of the third row can be divided into region 5. The electrode units 112 in each region (1-5) correspond to a column group in the circuit connection shown in Figure 2, and the corresponding 20 electrode units 112 are arranged in a four-row group and a five-column group in the circuit connection. In some other embodiments, the 20 electrode units 112 can also be arranged in other ways. Of course, in other embodiments, the electrode sheet 110 may also have other numbers of electrode units 112. In short, the implementation of this application is not limited by the number and arrangement of the electrode units 112 of the electrode sheet 110.

[0049] Each electrode unit 112 can be applied with an alternating electrical signal, thereby the paired electrode sheets 110 are used to apply an alternating electric field to the tumor site of the patient. Optionally, the electrode unit 112 is a dielectric element, such as a ceramic sheet, or it can be a polymer dielectric layer made of polymer material. Each temperature detection unit 113 is provided corresponding to one electrode unit 112 to detect the temperature at the corresponding electrode unit 112. Each temperature detection unit 113 can be provided at any position of the corresponding electrode unit 112. In this embodiment, each electrode unit 112 is provided with a through hole 1121, which is suitable for installing the temperature detection unit 113. For example, each electrode unit 112 has a through hole 1121 in the middle, and each electrode unit 112 has a corresponding temperature detection unit 113 housed in the through hole 1121. Each temperature detection unit 113 includes a temperature sensor 114 and a diode 115. The temperature sensor 114 has a signal terminal 114B and a ground terminal 114A. The diode 115 has an anode 115B and a cathode 115A. The anode 115B of the diode 115 is connected to the ground terminal 114A of the temperature sensor 114, and the cathode 115A of the diode 115 serves as the temperature detection unit.The ground terminal 113A of 113 and the signal terminal 114B of the temperature sensor 114 serve as the signal terminal 113B of the temperature detection unit 113. The temperature sensor 114 can be a thermistor or other temperature sensors besides the thermistor. Each temperature sensor 114 is provided with a corresponding diode 115. The diode 115 is connected in series with the temperature sensor 114 of the corresponding electrode unit 112. It can prevent the reverse flow of current to prevent the detection signal from other electrode units 112 from affecting the temperature sensor 114.

[0050] As shown in FIG2, the electrode sheet 110 of this embodiment includes four grounding wires 118. Each grounding wire 118 is used to ground the ground terminals 113A of the temperature detection units 113 in the same row group. The four grounding wires 118 of the electrode sheet 110 are the first grounding wire 118-1, the second grounding wire 118-2, the third grounding wire 118-3, and the fourth grounding wire 118-4. In the four rows of electrode sheet 110, the first row includes electrode units 112-1 to 112-5, the second row includes electrode units 112-6 to 112-10, the third row includes electrode units 112-11 to 112-15, and the fourth row includes electrode units 112-16 to 112-20. Specifically, the first grounding wire 118-1 is used to ground the grounding terminal 113A of the temperature detection unit 113 corresponding to each of the electrode units 112-1 to 112-5 in the first row group; the second grounding wire 118-2 is used to ground the grounding terminal 113A of the temperature detection unit 113 corresponding to each of the electrode units 112-6 to 112-10 in the second row group; the third grounding wire 118-3 is used to ground the grounding terminal 113A of the temperature detection unit 113 corresponding to each of the electrode units 112-11 to 112-15 in the third row group; and the fourth grounding wire 118-4 is used to ground the grounding terminal 113A of the temperature detection unit 113 corresponding to each of the electrode units 112-16 to 112-20 in the fourth row group. It should be noted that these grounding wires 118 can be selectively closed or opened. This can be achieved by connecting each grounding wire 118 in series with a control switch 124. That is, the grounding terminal 113A of the temperature detection unit 113 corresponding to each electrode unit 112 in each row group is connected to the grounding pin through a control switch 124, which will be described in detail below. The above-mentioned "grounding the electrode unit 112" can refer to grounding the grounding terminal 114A of the temperature sensor 114 corresponding to each electrode unit 112, or it can refer to the diode 115 being connected in series with the temperature sensor 114 corresponding to the same electrode unit 112 and grounded together. In shortEach grounding wire 118 short-circuits and grounds the grounding terminals 113A of the temperature detection units 113 corresponding to all electrode units 112 in each row group.

[0051] As shown in FIG2, the electrode sheet 110 of this embodiment also includes five dual-purpose signal lines 119. One end of each dual-purpose signal line 119 is connected to all electrode units 112 in each column group, and the other end is connected to the adapter 120 for receiving temperature detection signals and transmitting alternating electrical signals. That is, for each row group, each dual-purpose signal line 119 can be selectively connected to one of the electrode units 112 or not connected to any of the electrode units 112 in the row group to avoid the dual-purpose signal line 119 outputting repeated signals in the future. Specifically, the five dual-purpose signal lines 119 of the electrode sheet 110 include a first dual-purpose signal line 119-1, a second dual-purpose signal line 119-2, a third dual-purpose signal line 119-3, a fourth dual-purpose signal line 119-4, and a fifth dual-purpose signal line 119-5. One end of the first dual-purpose signal line 119-1 is simultaneously connected to the signal terminal 113B of four electrode units 112 (electrode units 112-1, 112-6, 112-11, and 112-16) and their respective temperature detection units 113; one end of the second dual-purpose signal line 119-2 is simultaneously connected to the signal terminal 113B of four electrode units 112 (electrode units 112-2, 112-7, 112-12, and 112-17) and their respective temperature detection units 113; one end of the third dual-purpose signal line 119-3 is simultaneously connected to electrode units 112-3, 112-8, and 112-16. -13, Electrode units 112-18: four electrode units 112 and their corresponding temperature detection units 113, signal terminals 113B; One end of the fourth dual-purpose signal line 119-4 is simultaneously connected to the signal terminals 113B of the four electrode units 112 (112-4, 112-9, 112-14, 112-19, and their corresponding temperature detection units 113); One end of the fifth dual-purpose signal line 119-5 is connected to the signal terminals 113B of the four electrode units 112 (112-5, 112-10, 112-15, 112-20, and their corresponding temperature detection units 113). In short, each dual-purpose signal line 119 short-circuits the signal terminals 113B of each electrode unit 112 and its corresponding temperature detection unit 113 in parallel within the same column group as temperature sampling points (unlabeled) for connection to external devices. It should be noted that these dual-purpose signal lines 119 can selectively transmit alternating electrical signals or receive temperature detection signals. This can be achieved by connecting each dual-purpose signal line 119 in series with a bidirectional switching switch 125 and grounding it.The closure or opening of 118 is achieved. In other words, after the signal terminal 113B of each temperature detection unit 113 in each column group is shorted to the corresponding electrode unit 112, they are connected to a switching unit (unlabeled) through a dual-purpose signal line 119. This switching unit (unlabeled) includes multiple bidirectional switching switches 125, configured to switch the dual-purpose signal line 119 to either a temperature sampling point (unlabeled) or an alternating power supply line 127. When the dual-purpose signal line 119 is connected to a temperature sampling point (unlabeled), the switching state of the control switch 124 is configured so that the temperature detection signal detected by the corresponding temperature detection unit 113 in each row group is sampled based on the temperature sampling point (unlabeled). When the dual-purpose signal line 119 is connected to the alternating power supply line 127, an alternating electrical signal is applied to the electrode unit 112 of at least one column group based on the alternating power supply line 127. The analog temperature signal detected by each sampled temperature detection unit 113 is used to determine the test code array of the corresponding electrode piece 110, as described on page 8 / 27 of the specification, 11 CN. 121265986 A compares the test code array with the preset standard code array to perform quality inspection on the electrode sheet 110. For example, during the use of the electrode sheet 110, the fault condition of each temperature detection unit 113 in the corresponding electrode sheet 110 is identified, or during the production process of the electrode sheet 110, it is determined whether the corresponding electrode sheet 110 is qualified. The details will be described in detail below.

[0052] The multi-path grounding wire 118 and the multi-path dual-purpose signal line 119 are both conductive traces embedded in the substrate 111. The substrate 111 is electrically connected to the first cable 116. The multi-path grounding wire 118 and the multi-path dual-purpose signal line 119 embedded in the substrate 111 are electrically connected to the corresponding wires (not shown) in the first cable 116 one by one.

[0053] The tumor electric field therapy system 100 of this embodiment includes at least one pair of electrode pads 110 as described above, an adapter 120 electrically connected to the electrode pads 110, and an electric field generator 130 electrically connected to the adapter 120. The adapter 120 is connected between the electrode pads 110 and the electric field generator 130. The electric field generator 130 provides alternating electrical signals to the plurality of electrode units 112 of the electrode pads 110 via the adapter 120 and the dual-purpose signal line 119 of the electrode pads 110, or is used to receive temperature detection signals output by the temperature detection units 113 corresponding to the plurality of electrode units 112. The adapter 120 transmits the alternating electrical signals generated by the electric field generator 130 to the dual-purpose signal line 119 of the electrode pads 110, and is also configured to receive temperature detection signals output by the multiple dual-purpose signal lines 119 of the electrode pads 110.

[0054] Referring to Figures 2 and 3, the adapter 120 includes: a first controller 121, and multiple devices connected to the first controller 121.The adapter 120 includes multiple ADC units 122, multiple voltage-changing resistors 123 corresponding to each ADC unit 122, multiple control switches 124, multiple bidirectional switching switches 125 connected to each ADC unit 122, a first communication unit 126, an alternating power supply line 127 connected to each bidirectional switching switch 125, and a first power module 128 connected to the first communication unit 126, the first controller 121, and the multiple ADC units 122. The first power module 128 provides DC power VCC to each electronic component of the adapter 120. The adapter 120 also includes multiple circuit lines (unlabeled), which are electrically connected to multiple ground lines 118 and multiple dual-purpose signal lines 119 in the substrate 111 of the corresponding electrode plate 110 via first cables 116. The multiple circuit lines (unlabeled) include an alternating power supply line 127 that transmits alternating electrical signals to the corresponding electrode 110 and is electrically connected to the multiple dual-purpose signal lines 119 in the substrate 111 of the corresponding electrode 110; multiple circuit lines (unlabeled) that are electrically connected one-to-one to the multiple dual-purpose signal lines 119 in the substrate 111 of the corresponding electrode 110 and are used to power each temperature detection unit 113 of the electrode 110 or transmit the temperature detection signal of the electrode 110; and multiple circuit lines (unlabeled) that are electrically connected one-to-one to the multiple grounding lines 118 in the substrate 111 of the corresponding electrode 110. The number L of circuit lines electrically connecting the adapter 120 to one electrode piece 110 is equal to the sum of the number of rows and columns of the electrode units 112 of the electrode piece 110; the number H of circuit lines electrically connecting the adapter 120 to X electrode pieces 110 is equal to X times the number of circuit lines electrically connecting it to a single electrode piece 110, that is, H=XL=X×(M+N). The number of groups of control switches 124 and the number of groups of bidirectional switching switches 125 are related to the number of electrode pieces 110. The number of groups of control switches 124 is the same as the number of groups of bidirectional switching switches 125, and is not less than the number of electrode pieces 110. Optionally, the number of groups of control switches 124 and bidirectional switching switches 125 is the same as the number of electrode pieces 110. The following is a detailed description of the electrical connection between an electrode piece 110 with 20 electrode units 112 and the adapter 120.

[0055] Each group of control switches 124 is provided with multiple control switches 124. These multiple control switches 124 are respectively connected to the adapter 120 and electrically connected to circuit lines (unlabeled) corresponding one-to-one with the multiple grounding wires 118 of a corresponding electrode piece 110, and are configured to control the on / off state of the multiple grounding wires 118. The circuit lines (unlabeled) that are each electrically connected to the multiple grounding wires 118 of the electrode piece 110 are grounded to GND at the end closest to the control switch 124. Each group of control switches...The number of control switches 124 in group 124 is related to the number of grounding wires 118 on the substrate 111 of the corresponding electrode sheet 110, that is, to the number of rows in which multiple electrode units 112 are configured. In this embodiment, the two are equal. As shown in FIG2, in this embodiment, the multiple control switches 124 in each group of control switches 124 are respectively the first control switch 124-1, the second control switch 124-2, the third control switch 124-3, and the fourth control switch 124-4. The multiple control switches 124 in the same group control the closing or opening of the corresponding grounding wire 118 of the same electrode sheet 110. Specifically, the first control switch 124-1 is used to control the opening or closing of the first grounding wire 118-1 of the corresponding electrode plate 110, and can cooperate with the corresponding set of bidirectional switching switches 125 to control the energization and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 in the first row of the electrode plate 110; the second control switch 124-2 is used to control the opening or closing of the second grounding wire 118-2 of the electrode plate 110, and can cooperate with the corresponding set of bidirectional switching switches 125 to control the energization and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 in the second row of the electrode plate 110. The first control switch 124-3 controls the energization and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 in the third row of the electrode plate 110, and the second control switch 124-3 controls the opening and closing of the third grounding wire 118-3 of the electrode plate 110. This, in conjunction with the corresponding set of bidirectional switching switches 125, controls the energization and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 in the third row of the electrode plate 110, from electrode units 112-11 to 112-15.

The control switch 124 can be a mechanical switch, such as a relay. The control switch 124 can also be an electronic switch, and each control switch 124 can be opened and closed by an additional first controller 121.

[0056] In this embodiment, all sets of control switches 124 are electronic switches. The first controller 121 is communicatively connected to the multiple sets of control switches 124 and is used to sequentially and cyclically control the opening and closing states of multiple control switches 124 in each set of control switches 124, thereby sequentially and individually turning on each grounding wire 118 of the multiple grounding wires 118 of the corresponding electrode pad 110 and cooperating with the switching of the corresponding bidirectional switching switch 125 to collect the temperature of the patient's body surface detected by all temperature detection units 113 on the electrode pad 110.The number of group control switches 124 is not less than the number of grounding wires 118 on the substrate 111 of the corresponding electrode piece 110.

Since the number of columns in which the multiple electrode units 112 of an electrode sheet 110 are configured is related to the number of electrode units 112 in a row group with the most electrode units 112, the number of bidirectional switching switches 125 in each group of bidirectional switching switches 125 is also related to the number of electrode units 112 in a row group with the most electrode units 112 in the corresponding electrode sheet 110; in this embodiment, the two are equal. Each bidirectional switch 125 has two ends labeled 1 and 2. The ends of multiple bidirectional switches 125 in the same group are electrically connected to the corresponding detection channels of the multiple detection channels of the corresponding group of ADC units 122 through temperature sampling points (unlabeled).

When both ends of each bidirectional switch 125 are on and one end is off, alternating electrical signals can be transmitted to each electrode unit 112 of the corresponding electrode plate 110. When one end of each bidirectional switch 125 is on and both ends are off, it can communicate with the corresponding control group.The control switches 124 in the control switch 124 cooperate to sequentially and time-divisionally transmit the temperature detection signals collected by the temperature detection units 113 of each electrode unit 112 on the electrode pad 110. The bidirectional switching switch 125 can be a mechanical switch, such as a relay. The bidirectional switching switch 125 can also be an electronic switch, and each bidirectional switching switch 125 can be switched by an additional first controller 121.

[0059] In this embodiment, all sets of bidirectional switching switches 125 are electronic switches. The first controller 121 is communicatively connected to the multiple sets of bidirectional switching switches 125 and is used to control the multiple bidirectional switching switches 125 in each set of bidirectional switching switches 125 to switch between their respective terminals 1 and 2, and cooperate with the closing or opening of the corresponding control switch 124 to continuously monitor the temperature of the patient's body surface detected by all temperature detection units 113 on the electrode pad 110 or to transmit alternating electrical signals to the patient.

[0060] In this embodiment, each ADC unit 122 is electrically connected to one end of one of the multiple bidirectional switching switches 125 in the corresponding group of bidirectional switching switches 125 through multiple circuit lines (unlabeled) in the adapter 120, and is configured to receive the temperature detection signal transmitted by the multi-channel dual-purpose signal line 119 of the corresponding electrode 110, and convert the temperature detection signal from analog signal to digital signal. Each ADC unit 122 includes multiple detection channels A, B, C, D, and E that are set one-to-one with the corresponding temperature detection points (unlabeled). Each detection channel A, B, C, D, and E is used to connect to one of the corresponding dual-purpose signal lines 119 in the multi-channel dual-purpose signal line 119 through the corresponding bidirectional switching switch 125. As shown in FIG2, each ADC unit 122 includes a total of 5 detection channels A, B, C, D, and E, which are 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, respectively. The first detection channel A is connected to the first dual-purpose signal line 119-1 via terminal 1 of the first bidirectional switch 125-1; the second detection channel B is connected to the second dual-purpose signal line 119-2 via terminal 1 of the second bidirectional switch 125-2; the third detection channel C is connected to the third dual-purpose signal line 119-3 via terminal 1 of the third bidirectional switch 125-3; the fourth detection channel D is connected to the fourth dual-purpose signal line 119-4 via terminal 1 of the fourth bidirectional switch 125-4; and the fifth detection channel E is connected to the fifth dual-purpose signal line 119-5 via terminal 1 of the fifth bidirectional switch 125-5. Each detection channel A, B, C, D, and E is used to receive the temperature detection signal collected by the temperature detection unit 113 corresponding to the electrode unit 112 connected to the corresponding dual-purpose signal line 119. Furthermore, each detection channel A, B, C, D, and E is connected to a corresponding voltage divider resistor 123 within the adapter 120.A first power supply module 128 provides detection voltage to the detection channels A, B, C, D, and E, and the first power supply module 128 provides DC power.

[0061] In this embodiment, the first controller 121 is also configured to determine the test code array of the corresponding electrode plate 110 based on the simulated temperature signal detected by each sampled temperature detection unit 113, and to compare the test code array with the standard code array to identify the fault condition of each temperature detection unit 113 in the corresponding electrode plate 110. The standard code array is the code array when the electrode plate 110 is qualified. The adapter 120 may also include a reminder unit (not shown). When the first controller 121 still finds a faulty temperature detection unit 113 in the electrode plate 110, it controls the reminder unit (not shown) to issue a first reminder message and instructs the electric field generator 130 to continue working. For example, when there is no faulty temperature detection unit 113 in the electrode plate 110, the control reminder unit (not shown) will light up green, and when there is a faulty temperature detection unit 113 in the electrode plate 110, the control reminder unit (not shown) will light up red.

[0062] In this embodiment, the first controller 121 is also configured to determine the number of faulty temperature detection units 113 in the electrode plate 110 when comparing the test code array with the standard code array, and to determine whether the electrode plate 110 needs to be replaced based on the number. For example, when the number exceeds a preset number (which can be set to a minimum of 1), it is determined that the electrode plate 110 needs to be replaced, and when the number does not exceed the preset number, it is determined that the electrode plate 110 does not need to be replaced. The first controller 121 can also control the reminder unit (not shown) to issue a second reminder message and instruct the electric field generator 130 to stop working when it is determined that the electrode plate 110 needs to be replaced. For example, when the first controller 121 determines that the electrode plate 110 needs to be replaced, it controls the reminder unit (not shown) to light up red and flash, and at the same time controls the reminder unit (not shown) to sound an alarm, such as a buzzer.

[0063] In this embodiment, the first communication unit 126 is configured to acquire digital signals output by multiple ADC units 122 and send the digital signals to the electric field generator 130. The electric field generator 130 is also configured to control and adjust the voltage of the alternating electrical signal provided to the multiple electrode units 112 of the electrode plate 110 according to the received digital signal. For example, when any digital signal among the multiple received digital signals exceeds a preset threshold, it means that the temperature detected by the temperature detection unit 113 corresponding to at least one electrode unit 112 in the electrode plate 110 exceeds the preset temperature threshold (e.g., 41°C, 42°C, etc.). At this time, the voltage of the alternating electrical signal output by the electric field generator 130 can be appropriately reduced to avoid the electrode units 112 of the electrode plate 110 from being subjected to alternating current.The temperature is too high when the electrical signal is active, causing low-temperature burns to the patient's skin. The aforementioned preset temperature threshold and preset threshold can be determined according to human safety thresholds. The first communication unit 126 is controlled by the first controller 121 and serially transmits digital signals converted by multiple ADC units 122. In this embodiment, the preset temperature threshold can be a value within the range of 36℃-45℃. In this embodiment, the electric field generator 130 is also configured to determine the test code array of the corresponding electrode 110 based on the analog temperature signal detected by each sampled temperature detection unit 113, and to compare the test code array with the standard code array to identify the fault condition of each temperature detection unit 113 in the corresponding electrode 110.

[0068] In this embodiment, the second controller 131 is further configured to determine the number of faulty temperature detection units 113 in the electrode sheet 110 when comparing the test code array with the standard code array, and to determine whether the electrode sheet 110 needs to be replaced based on the number. For example, if the number exceeds a preset number (which can be set to a minimum of 1), it is determined that the electrode sheet 110 needs to be replaced; if the number does not exceed the preset number, it is determined that the electrode sheet 110 does not need to be replaced. The second controller 131 can also control the reminder unit (not shown) to issue a second reminder message and control the AC signal to be sent when it is determined that the electrode sheet 110 needs to be replaced.The generator 132 stops working. For example, when the second controller 131 determines that the electrode sheet 110 needs to be replaced, it controls the reminder unit (not shown) to light up red and flash, and at the same time controls the reminder unit (not shown) to sound an alarm (such as a buzzer).

[0069] In this embodiment, the first controller 121 or the second controller 131 is also configured to send the test code array to the host computer (not shown) so that the host computer (not shown) can compare the test code array with the standard code array to determine whether the electrode sheet 110 is qualified. For example, the first controller 121 sends the test code array to the host computer (not shown) via the electric field generator 130, or directly to the host computer (not shown), so that the host computer (not shown) can compare the test code array with the standard code array to determine whether the electrode pad 110 is qualified; or, the second controller 131 sends the test code array to the host computer (not shown), so that the host computer (not shown) can compare the test code array with the standard code array to determine whether the electrode pad 110 is qualified. The host computer (not shown) may be connected to a display (not shown) to control the display (not shown) to display the test code array, the standard code array, and whether the electrode pad 110 is qualified. The host computer (not shown) is also connected to an alarm to control the alarm (not shown) to issue a reminder message when the electrode pad 110 is unqualified.

[0070] The working principle of the tumor electric field therapy system 100 of this embodiment will be described in detail below with reference to Figures 2 to 4.

[0071] Specifically, when it is necessary to detect the temperature at each electrode unit 112 of an electrode plate 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls each of the multiple bidirectional switching switches 125 electrically connected to the electrode plate 110 to turn on one end and turn off the other end, so as to disconnect the alternating electrical signal applied to the electrode plate 110; at the same time, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls each of the control switches 124 electrically connected to the electrode plate 110 to turn on sequentially and time-divisionally. At this time, the multiple detection channels A, B, C, D, E of a set of ADC units 122 corresponding to the electrode plate 110 can be used to sequentially and time-divisionally collect the temperature data collected by each temperature detection unit 113 corresponding to each electrode unit 112 in each row of the electrode plate 110. (Instruction manual 15 / 27 pages 18 CN) 121265986 A temperature detection signal. Each detection channel A, B, C, D, and E of each ADC unit 122 simultaneously only acquires the temperature detection signal from the temperature detection unit 113 corresponding to each electrode unit 112 in the same row group of the electrode sheet 110. The aforementioned temperature detection signals can...Characterized by voltage values. Of the four control switches 124 corresponding to the electrode 110, only one can be on at a time, while the other three are off. All five bidirectional switches 125 of the set of bidirectional switches 125 corresponding to the ADC unit 122 are switched to their respective terminals 1, so that each dual-purpose signal line 119 of the electrode 110 is electrically connected to the corresponding detection channels A, B, C, D, and E of the ADC unit 122, thus enabling conduction. With this configuration, the ADC unit 122 can acquire the voltage values ​​of all temperature detection units 113 corresponding to each electrode unit 112 in the same row group that are shorted by a grounding line 118 corresponding to the on control switch 124.

[0072] Specifically, when control switch 124-1 is closed, control switches 124-2, 124-3, and 124-4 are all open, and the first bidirectional switching switch 125-1, the second bidirectional switching switch 125-2, the third bidirectional switching switch 125-3, the fourth bidirectional switching switch 125-4, and the fifth bidirectional switching switch 125-5 are all switched to their respective terminals 1, the temperature detection units 113 corresponding to electrode units 112-1 to 112-5 in the first row group are energized, and the electrode units 112-6 in the remaining rows are energized. When the temperature detection units 113 corresponding to electrode units 112-20 are de-energized, the signal terminals 113B of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, 112-11, and 112-16 in the first detection channel A of the ADC unit 122 are shorted. Since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-1 is grounded, the temperature detection units 113 corresponding to electrode units 112-6, 112-11, and 112-16 are not grounded. The grounding terminal 113A of element 113 is disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114. This does not affect the resistance value of the temperature detection unit 113 corresponding to electrode unit 112-1. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-1 is effectively operating on the first detection channel A of this group of ADC units 122. The temperature detection signal (voltage value) acquired by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-1. Similarly, the voltage value acquired on the second detection channel B of this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-2. The voltage value acquired on the third detection channel C of this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-3. The fourth detection channel of this group of ADC units 122...The voltage value collected on channel D is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-4. The voltage value collected on the fifth detection channel E in the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-5.

[0073] When control switch 124-2 is closed, control switches 124-1, 124-3 and 124-4 are all open, and the first bidirectional switching switch 125-1, the second bidirectional switching switch 125-2, the third bidirectional switching switch 125-3, the fourth bidirectional switching switch 125-4 and the fifth bidirectional switching switch 125-5 are all switched to their respective terminals 1, the temperature detection units 113 corresponding to electrode units 112-6 to 112-10 of the second row group are energized, and the electrode units 112-1 to 112-5 and electrode units 112-11 to 112-2 of the other rows are energized. When the temperature detection units 113 corresponding to 0 are de-energized, the signal terminals 113B of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, 112-11, and 112-16 in the first detection channel A of the ADC unit 122 are shorted. Since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-6 is grounded, while the temperature detection units 112-1, 112-6, 112-11, and 112-16 are shorted, the signal terminals 113B of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, 112-11, and 112-16 are shorted. The grounding terminal 113A of each of the 16 corresponding temperature detection units 113 is disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114. This does not affect the resistance value of the temperature detection unit 113 corresponding to electrode units 112-6. Therefore, only the temperature detection unit 113 corresponding to electrode units 112-6 is effectively operating on the first detection channel A of this group of ADC units 122. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-6. Similarly, the voltage value collected on the second detection channel B of this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-7. The voltage value collected on the third detection channel C of this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-8. The voltage value acquired on the fourth detection channel D in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-9. The voltage value acquired on the fifth detection channel E in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-10.

[0074] When control switch 124-3 is closed, and control switches 124-1, 124-2, and 124-4 are all open, and the first bidirectional switching switch 125-1, the second bidirectional switching switch 125-2, the third bidirectional switching switch 125-3, the fourth bidirectional switching switch 125-4, and the fifth bidirectional switching switch 125-5 are all switched to their respective terminals 1, the temperature detection units 113 corresponding to electrode units 112-11 to 112-15 in the third row group are energized, while the temperature detection units 113 corresponding to electrode units 112-1 to 112-10 and electrode units 112-16 to 112-20 in the other rows are de-energized. In this group of ADC units 122, electrode units 112-1, 112-6, and 112-11 are short-circuited on the first detection channel A. Since only the grounding terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-11 is grounded, while the grounding terminals 113A of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, and 112-16 are disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, it will not affect the resistance value of the temperature detection unit 113 corresponding to electrode unit 112-11. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-11 is effectively operating on the first detection channel A of this ADC unit 122. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-11. Similarly, the voltage value acquired on the second detection channel B in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-12. The voltage value acquired on the third detection channel C in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-13. The voltage value acquired on the fourth detection channel D in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-14. The voltage value acquired on the fifth detection channel E in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-15.

[0075] When control switch 124-4 is closed, control switches 124-1, 124-2, and 124-3 are all open, and the first bidirectional switching switch 125-1, the second bidirectional switching switch 125-2, the third bidirectional switching switch 125-3, the fourth bidirectional switching switch 125-4, and the fifth bidirectional switching switch 125-5 are all switched to their respective terminals 1, and the electrode units of the fourth row group...Temperature detection units 113 corresponding to electrode units 112-16 to 112-20 are powered on, while temperature detection units 113 corresponding to electrode units 112-1 to 112-15 in the remaining rows are de-powered. The signal terminals 113B of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, 112-11, and 112-16 are shorted on the first detection channel A of this group of ADC units 122. Since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-16 is grounded, while the ground terminals 113A of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, and 112-11 are disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a connection to the temperature sensor 114... The series-connected diode 115 does not affect the resistance of the temperature detection unit 113 corresponding to electrode units 112-16. Therefore, only the temperature detection unit 113 corresponding to electrode units 112-16 is effectively operating on the first detection channel A of this ADC unit 122. At this time, the temperature detection signal (voltage value) acquired by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-16. Similarly, the voltage value acquired on the second detection channel B of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-17. The voltage value acquired on the third detection channel C of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-18. The voltage value acquired on the fourth detection channel D of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-19. The voltage value collected on the fifth detection channel E in the ADC unit 122 of this instruction manual (pages 17 / 27, CN 121265986 A) is the voltage value of the temperature detection unit 113 corresponding to the electrode units 112-20.

[0076] Thus, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can collect the temperature detection signals of the temperature detection units 113 corresponding to all electrode units 112 of the electrode unit 110 by controlling a set of bidirectional switching switches 125 and a set of control switches 124 that are electrically connected to a certain electrode piece 110. That is, the switching unit (unlabeled) is configured to switch the dual-purpose signal lines 119 corresponding to at least two column groups to be connected to the corresponding temperature sampling points (unlabeled) at the same time, and the switching state of the corresponding control switches 124 is configured so that the temperature detection signals detected by the corresponding temperature detection units 113 in each row group are sampled based on the corresponding temperature sampling points (unlabeled). Similarly, the temperature detection signals of the temperature detection units 113 of each electrode unit 112 of other electrode sheets 110 can be obtained.

[0077] The first controller 121 or the second controller 131, multiple ADC units 122, and multiple bidirectional switching switches 125 can automatically execute operations through pre-programmed program code. For example, the first controller 121 or the second controller 131 first controls all bidirectional switching switches 125 in the corresponding group to switch to end 1, so that end 1 of these bidirectional switching switches 125 is all turned on and end 2 is all turned off, so that each dual-purpose signal line 119 of the corresponding electrode plate 110 is electrically connected to the corresponding group of ADC units 122. Then, the control switch 124-1 in the corresponding group of control switches 124 is closed, and the remaining control switches 124-2 to 124-4 in the group of control switches 124 are turned off. During this period, each detection channel A, B, C, D, and E of the group of ADC units 122 acquires the temperature detection signal of each temperature detection unit 113 corresponding to each electrode unit 112 in the first row of the corresponding electrode plate 110, converts it into a digital signal, and stores it in a separately set memory. Then, after a preset time interval, The first controller 121 or the second controller 131 then closes control switch 124-2 in the group of control switches 124, and opens control switches 124-1, 124-3, and 124-4 in the same group of control switches 124. During this period, each detection channel A, B, C, D, and E of the ADC unit 122 acquires the temperature detection signal of each temperature detection unit 113 corresponding to each electrode unit 112 located in the second row group. By sequentially and individually turning on each control switch 124 in the group of control switches 124, the temperature detection signals of all temperature detection units 113 on the electrode plate 110 can be obtained. Similarly, through this operation, the temperature detection signals of all temperature detection units 113 on at least one pair of electrode plates 110 can be obtained.

[0078] It should be noted that, in some other embodiments, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can also control a set of bidirectional switching switches 125 and a set of control switches that are electrically connected to a certain electrode plate 110 to collect the temperature detection signal of the temperature detection unit 113 corresponding to a part of the electrode unit 112 of the electrode plate 110 during the same temperature acquisition time period. For example, when only the first bidirectional switch 125-1 is switched to its terminal 1, switch 124-1 can be closed first, and switches 124-2, 124-3, and 124-4 can be opened. At this time, only the temperature detection unit 113 corresponding to the electrode unit 112-1 of the first row group is energized. The signal terminal 113B of the temperature detection unit 113 corresponding to the electrode unit 112-1 is shorted on the first detection channel A of the ADC unit 122 of this group. Therefore, the ADC unit 122 of this group will detect the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-1. Then, switch 124-2 is closed, and the control...When control switches 124-1, 124-3, and 124-4 are all open, the ADC unit 122 will detect the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-6. Then, control switch 124-3 closes, and control switches 124-1, 124-2, and 124-4 are all open. The ADC unit 122 will then detect the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-11. Finally, control switch 124-4 closes, and control switches 124-1, 124-2, and 124-3 are all open. The ADC unit 122 will then detect the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-16. Therefore, within the same acquisition time period, only the temperature detection signal of the temperature detection unit 113 corresponding to one set of electrode units 112 can be sampled. Similarly, during other acquisition time periods, the temperature detection signals of the temperature detection units 113 corresponding to other column groups of electrode units 112 can be sampled. That is, the switching unit (unlabeled) is configured to switch the dual-purpose signal line 119 corresponding to each column group (page 18 / 27 of the specification, CN 121265986 A) to the corresponding temperature sampling point (unlabeled), and the switching state of the control switch 124 is configured so that the temperature detection signals detected by each temperature detection unit 113 in each column group are sampled separately. It should be noted that in some other embodiments, the temperature detection signals of the temperature detection units 113 corresponding to two, three, or four column groups of electrode units 112 can also be sampled during the same acquisition time period, which will not be described in detail here.

[0079] Specifically, when it is necessary to apply an alternating electrical signal to each electrode unit 112 of an electrode plate 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls each of the multiple bidirectional switching switches 125 of a set of bidirectional switching switches 125 electrically connected to the electrode plate 110 to turn on at two ends and turn off at one end. At the same time, it controls all the multiple control switches 124 of a set of control switches 124 electrically connected to the electrode plate 110 to turn off, and controls a power supply switch 133 electrically connected to the electrode plate 110 to turn on. At this time, the second controller 131 of the electric field generator 130 controls the AC signal generator 132 to apply an alternating electrical signal to each electrode unit 112 of the electrode plate 110 through the alternating power line 127, and the magnitude of the applied alternating electrical signal voltage or current is adjustable. That is, the switching unit (unlabeled) is configured to simultaneously connect the dual-purpose signal lines 119 corresponding to at least two column groups to the alternating power supply line 127, so that the electrode units 112 of at least two column groups are simultaneously subjected to alternating electrical signals based on the alternating power supply line 127.

[0080] It should be noted that in other embodiments, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can also control a set of bidirectional switching switches 125 electrically connected to a certain electrode plate 110 to apply alternating electrical signals to a portion of the electrode units 112 of the electrode plate 110 at the same time period. For example, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls the first bidirectional switch 125-1 of a group of bidirectional switches 125 electrically connected to the electrode plate 110 to turn on at both ends and turn off at the other end. At the same time, it controls all the control switches 124 of a group of control switches 124 electrically connected to the electrode plate 110 to turn off, and controls a power supply switch 133 electrically connected to the electrode plate 110 to turn on. At this time, the second controller 131 of the electric field generator 130 controls the AC signal generator 132 to apply an alternating electrical signal to the first column of electrode units 112-1, 112-6, 112-11 and 112-16 of the electrode plate 110 through the alternating power line 127, and the magnitude of the applied alternating electrical signal voltage or current is adjustable. That is, the switching unit (unlabeled) is configured to switch the dual-purpose signal line 119 corresponding to each column group to the alternating power supply line 127 respectively, so that the electrode unit 112 of each column group is simultaneously applied with an alternating electrical signal based on the alternating power supply line 127. It should be noted that in some other embodiments, alternating electrical signals can also be applied to two, three, or four column groups of electrode units 112 at the same time period, which will not be detailed here.

[0081] Specifically, during the use of the electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can determine the test code array of the electrode sheet 110 based on the temperature detection signal detected by each temperature detection unit 113, and compare the test code array with the standard code array to monitor whether the electrode sheet 110 is damaged, so as to replace the electrode sheet 110 in time and avoid or reduce the risk of low-temperature burns to patients. For example, the temperature sensor 114 in the temperature detection unit 113 is a negative temperature coefficient thermistor, which has the characteristic that the higher the temperature, the lower the resistance, and the lower the temperature, the higher the resistance. Since the electrode plate 110 is attached to the human body surface during use, and the human body surface temperature is generally between 36°C and 37°C, a negative temperature coefficient thermistor with a temperature range of 0°C to 50°C can be selected. For example, a thermistor with model number 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.

[0082] As shown in Figure 5, when any control switch 124 is turned on, the DC power supply VCC provides DC power to the voltage divider resistor 123, temperature sensor 114 and diode 115 in sequence. The ADC unit 122 in the adapter 120 collects the voltage between the temperature sensor 114 and the voltage divider resistor 123 through the corresponding acquisition channel, that is, the voltage division between the temperature sensor 114 and the diode 115 and the voltage divider resistor 123, and obtains the AD sampling value, i.e. the voltage value (the voltage value of the thermistor), as shown in the following formula (1): Manual 19 / 27 Page 22 CN 121265986 A

[0083] VADC=(VCC-VD)×R / (Rz+R) (1)

[0084] Wherein, VADC is the AD sampling value, i.e. the voltage value, VCC is also used to represent the voltage of the DC power supply, VD is the voltage drop of the diode 115, R is the resistance of the thermistor, and Rz is the resistance of the voltage divider resistor 123.

[0085] Assuming the voltage drop VD of diode 115 is 0.3V and the resistance Rz of voltage divider resistor 123 is 10KΩ, then when the temperature sensed by temperature sensor 114 is 0℃, 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 temperature sensor 114 is 25℃, the corresponding resistance is approximately 10.0KΩ. Based on formula (1), the corresponding AD sampling value V25 = (3.3 - 0.3) × 10 / (10+10)=1.50V; When the temperature sensed by the temperature sensor 114 is 50℃, the corresponding resistance is about 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 sensor 114 is disconnected, for example, due to abnormal welding of the temperature sensor 114 or open circuit of the temperature sensor 114, the corresponding AD sampling value can be obtained as 3.3V. When the temperature sensor 114 and diode 115 are short-circuited, the corresponding AD sampling value can be obtained as 0V.

[0086] Since the ADC unit 122 collects the voltage value of the temperature sensor 114, the temperature sensor 114 has different voltage values ​​corresponding to different temperatures. Therefore, the voltage value collected by the ADC unit 122 can be reasonably segmented for differentiation. At the same time, the voltage value is converted into the corresponding code. That is, the voltage range in which the voltage value is located corresponds to different codes. Based on the code, the test code array of the electrode sheet 110 can be determined. 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 detection unit 113 is in a normal state, the second code is used to indicate that the temperature detection unit 113 is in an open circuit state or an unset state, and the third code is used to indicate the temperature.The detection unit 113 is in a short-circuit state.

[0087] Specifically, taking the temperature sensor 114 sensing a temperature in the range of 0℃ to 50℃, and the AD sampling value obtained by the ADC unit 122 sampling, i.e., the voltage value, in the range of 0.88V to 2.20V, considering factors such as detection error, the voltage value range can be appropriately expanded to 0.5V to 3V.

[0088] When the AD sampling value obtained by the ADC unit 122 sampling is greater than 0.5V and less than 3V, the corresponding code is the first code, such as 1; when the AD sampling value obtained by the ADC unit 122 sampling is less than or equal to 0.3V, the corresponding code is the third code, such as 0; when the AD sampling value obtained by the ADC unit 122 sampling is greater than or equal to 3.1V, the corresponding code is the second code, such as 2. Therefore, in the corresponding detection positions numbered 1 to 20 of the electrode sheet 110, if the temperature sensor 114 is short-circuited, the corresponding code is 0, i.e., the third code; if there is a temperature sensor 114, the corresponding code is 1, i.e., the first code; if there is no temperature sensor 114 or the temperature sensor 114 is disconnected, the corresponding code is 2, i.e., the second code.

[0089] Referring to Figure 2, under normal circumstances, when the electrode sheet 110 has 20 electrode units 112, and each electrode unit 112 corresponds to a temperature sensor 114 and a diode 115, that is, the corresponding detection positions numbered 1 to 20 of the electrode sheet 110 all have a temperature sensor 114, and the code is 1. The 20 codes are combined to obtain a 20-bit standard code array 11111 11111 11111 11111. When temperature sensor 114 experiences an open circuit, assuming the temperature sensor at detection position 1 is open-circuited, the resulting 20-bit test code array is 21111 11111 11111 11111. When temperature sensor 114 experiences a short circuit, assuming the temperature sensor at detection position 1 is short-circuited, the resulting 20-bit test code array is 01111 11111 11111 11111. Similarly, under normal conditions, the standard code array for electrode plate 210 shown in Figure 6 is 1111 1111 1111 1111 1111.

[0090] Referring to Figure 10, under normal circumstances, when the electrode plate 410 has 13 electrode units 412, and each electrode unit 412 corresponds to a temperature sensor 414 and a diode 415, that is, the corresponding detection positions numbered 1 to 13 of the electrode plate 410 all have temperature sensors 414, and the codes are all 1. Combining the 13 codes, a 13-bit standard code array 11111 11111 111 is obtained. However, when the temperature sensor 414 is open-circuited, assuming that the temperature sensor 414 at detection position number 1 is connected to the specification 20 / 27 page 23 CN 121265986 AIf an open circuit occurs, the resulting 13-bit test code array is 21111 11111 111. However, if the temperature sensor 414 short-circuits, assuming the temperature sensor at detection bit 1 short-circuits, the resulting 13-bit code array is 01111 11111 111. Similarly, under normal conditions, the standard code array for electrode 510 shown in Figure 12 is 1111 1111 11111, the standard code array for electrode 610 shown in Figure 13 is 1111 1111 1111 1, and the standard code array for electrode 710 shown in Figure 15 is 111 111 111 1111.

[0091] Referring to Figure 19, under normal circumstances, when the electrode sheet 1010 has 9 electrode units 1012, and each electrode unit 1012 corresponds to a temperature sensor 1014 and a diode 1015, that is, when the corresponding detection positions numbered 1 to 9 of the electrode sheet 1010 all have temperature sensors 1014, and the codes are all 1, the 9 codes are combined to obtain a 9-bit standard code array 11111 1111. When the temperature sensor 1014 is open-circuited, assuming that the temperature sensor 1014 at detection position number 1 is open-circuited, the resulting 9-bit test code array is 21111 1111. When the temperature sensor 1014 is short-circuited, assuming that the temperature sensor 1014 at detection position number 1 is short-circuited, the resulting 9-bit test code array is 01111 1111. Similarly, the standard code array corresponding to the electrode sheet 1110 shown in Figure 21 is 111 111 111.

[0092] Based on the above coding rules, the quality of the electrode pad 110 can be inspected during use so that the electrode pad 110 can be replaced in time to avoid low-temperature burns. The specific process is as follows:

[0093] Step 1: Provide at least one pair of qualified electrode pads 110 (since the electrode pad 110 is a medical device, each electrode pad 110 will undergo multiple tests before leaving the factory to ensure that the electrode pad 110 is qualified. Therefore, the electrode pads 110 provided to the user are all qualified electrode pads 110). Connect at least one pair of qualified electrode pads 110 to the aforementioned adapter 120, and connect the aforementioned adapter 120 to the aforementioned electric field generator 130.

[0094] Step 2: Power on the electric field generator 130 to provide DC power VCC to the temperature detection unit 113 in at least one pair of qualified electrode pads 110 for temperature detection. The ADC unit 122 in the adapter 120 acquires the analog temperature signal detected by the temperature detection unit 113 of at least one pair of qualified electrode plates 110, and obtains several AD sampling values. The first controller 121 in the adapter 120 obtains at least two sets of standard code arrays A1 and A2 according to the aforementioned encoding rules. The at least two sets of standard code arrays A1 and A2 can be stored in the adapter 120 and used as comparison codes.

[0095] Step 3: Turn off the power to the electric field generator 130 and place the aforementioned at least one pair of qualified electrode pads 110 on the body surface corresponding to the tumor portion of the patient.

[0096] Step 4: Power on the electric field generator 130 to provide a DC power supply VCC to the temperature detection unit 113 in the at least one pair of qualified electrode pads 110 for temperature detection, and simultaneously provide an alternating electrical signal to the electrode unit 112 in the electrode pads 110 to form an alternating electric field between the paired electrode pads 110 for tumor electric field therapy. The ADC unit 122 in the adapter 120 collects the temperature signal detected by the temperature detection unit 113 of the at least one pair of qualified electrode pads 110 and obtains several AD sampling values. The first controller 121 in the adapter 120 obtains at least two sets of detection code arrays B1' and B2' according to the aforementioned encoding rules.

[0097] Step 5: The first controller 121 in the adapter 120 compares the detection code arrays B1' and B2' with the corresponding standard code arrays A1 and A2 one by one. If the detection code arrays B1' and B2' are consistent with the standard code arrays A1 and A2, then steps 4 and 5 are repeated. If at least one detection code array B1' or B2' is inconsistent with the standard code arrays A1 and A2, then step 6 is performed.

[0098] Step 6: The adapter 120 confirms the number of abnormal temperature detection units 113 in the electrode plate 110 corresponding to the inconsistent detection code arrays B1' and / or B2', and determines whether the number of abnormal temperature detection units 113 in the corresponding electrode plate 110 exceeds the upper limit. If it does not exceed the upper limit, then step 7 is performed. If it exceeds the upper limit, then step 8 is performed.

[0099] Step 7: Steps 4 and 5 are repeated.

[0100] Step 8: The adapter 120 issues an alarm through its internal reminder unit (not shown), and simultaneously sends a corresponding signal to the electric field generator 130 through the communication unit 126 on page 24 of the first specification (21 / 27, CN 121265986 A), so that the electric field generator 130 stops providing alternating electrical signals to the electrode unit 112 in the electrode plate 110, reminding the user to replace the corresponding electrode plate 110.

[0101] Step 9: Turn off the power to the electric field generator 130, remove the electrode plate 110 that needs to be replaced from the adapter 120, and connect the new electrode plate 110 to the adapter 120.

[0102] Step 10: Power on the electric field generator 130 to continue providing DC power VCC to the temperature detection unit 113 in the electrode plate 110 connected to the adapter 120 for temperature detection. The ADC unit 122 in the adapter 120 acquires the temperature signal detected by the temperature detection unit 113 of the replaced qualified electrode 110, and obtains several AD sampling values. The first controller 121 in the adapter 120 obtains a new standard code array A1' or / and A2' according to the aforementioned encoding rules, at least one new standard code array.The code array A1' or / and A2' is compared with the previously stored corresponding standard code array A1 or / and A2. If the new standard code array A1' or / and A2' matches the standard code array A1 or / and A2, the power supply of the electric field generator 130 is turned off, and the new electrode pad 110 is placed on the body surface corresponding to the tumor part of the patient. Then, steps four and five are repeated. If, after comparing the new standard code array A1' or / and A2' with the previously stored standard code array A1 or / and A2 one by one, there is at least one set of new standard code arrays A1' and / or A2' that does not match the previously stored and corresponding standard code arrays A1 and / or A2, steps nine and ten are repeated until the new standard code arrays A1' and / or A2' of the qualified electrode pad 110 that is replaced matches the previously stored and corresponding standard code arrays A1 and / or A2.

[0103] It should be noted that in the above steps, the paired electrode plates 110 can be electrode plates 110 with the same design, that is, the standard code arrays of the paired electrode plates 110 are the same, that is, the standard code arrays A1 and A2 are the same.

[0104] The above steps one and two can be replaced by the user inputting at least two sets of standard code arrays A1 and A2, and at least two sets of standard code arrays A1 and A2 can be stored in the adapter 120 and used as comparison codes.

[0105] In step six above, the number of abnormal temperature detection units 113 in the corresponding electrode sheet 110 is determined by comparing the inconsistent detection code arrays A1' and / or A2' with the corresponding standard code arrays A1 and A2 and finding differences in the number of codes. For example, if A1' is compared with A1 and only the first code is different, then the number of abnormal temperature detection units 113 in the corresponding electrode sheet 110 is 1; or if A1' is compared with A1 and only the last two codes are different, then the number of abnormal temperature detection units 113 in the corresponding electrode sheet 110 is 2; and so on.

[0106] In step six above, the upper limit can be set to 1, that is, if there is one abnormal temperature detection unit 113 on the electrode sheet 110, then step eight (alarm and replacement of electrode sheet 110) is performed. In other embodiments, in step six above, the upper limit is not limited to 1, and can also be a positive integer close to the proportion of the number of temperature detection units 113 in the electrode sheet 110.

[0107] In step eight above, the reminder unit (not shown) may include at least two indicator lights (not shown) corresponding one-to-one with the electrode pads 110, indicating the status of the corresponding electrode pad 110. When the electrode pad 110 does not need to be replaced, the indicator lights (not shown) are all green; when the electrode pad 110 needs to be replaced, the indicator light (not shown) of the electrode pad 110 to be replaced is red. Alternatively, the status of the electrode pad 110 not needing to be replaced or needing to be replaced can be indicated by the indicator lights (not shown) being constantly lit or flashing.

[0108] In step eight above, the reminder unit (not shown) may also include a buzzer (not shown) to indicate the status of the electrode pad 110.The status is simultaneously alerted to the user by the indicator light (not shown). When the electrode 110 does not need to be replaced, the buzzer (not shown) does not sound an alarm; when the electrode 110 needs to be replaced, the buzzer (not shown) sounds an alarm.

[0109] While comparing the detection code array with the standard code array in steps four, five, and six above, temperature monitoring is also performed simultaneously. The steps include the following:

[0110] Step eleven: The first controller 121 in the adapter 120 calculates the digital temperature signal detected by the temperature detection unit 113 based on several AD sampling values, and determines whether the digital temperature signal exceeds the preset temperature. If the digital temperature signal detected by the temperature detection unit 113 of the electrode 110 exceeds the preset temperature, then proceed to step twelve; if the digital temperature signal detected by the temperature detection unit 113 of the electrode 110 is below the preset temperature, then continue to step eleven.

[0111] Step Twelve: When the first controller 121 in the adapter 120 detects that the temperature detected by the temperature detection unit 113 of the electrode 110 exceeds the preset temperature, it sends a corresponding signal through the first communication unit 126 so that the electric field generator 130 reduces or shuts down the corresponding alternating current signal until the temperature detected by the temperature detection unit 113 of the corresponding electrode 110 is below the preset temperature. The preset temperature can be in the range of 39℃ to 41℃, preferably 40.5℃.

[0112] It should be noted that the above process is described using the adapter 120 for quality monitoring of the electrode 110 as an example. Quality monitoring of the electrode 110 can also be performed by the electric field generator 130, or partially by the adapter 120 and the electric field generator 130 respectively. Details will not be elaborated here. Furthermore, the number of electrode 110s, the number of electrode units 112 in each electrode 110, and the setting of the sampling code are all exemplary descriptions and are not intended to limit this application.

[0113] Specifically, during the production process of the electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can send the test code array of the electrode sheet 110 to the host computer (not shown), so that the host computer (not shown) can compare the test code array with the standard code array to monitor whether each temperature detection unit 113 of the electrode sheet 110 is properly connected, thereby determining whether the electrode sheet 110 is qualified, so as to screen out unqualified electrode sheets 110, thereby ensuring that each temperature detection unit 113 of the electrode sheet 110 leaving the factory can be tested normally. Among them, the standard code array includes at least the first code of the first code and the second code. The specific process is as follows:

[0114] Step 1: Provide a qualified electrode sheet 110, connect the electrode sheet 110 to the aforementioned adapter 120, the aforementioned adapterThe adapter 120 is connected to the aforementioned electric field generator 130, which is also connected to a host computer (not shown, such as a computer). The host computer (not shown) is also connected to a display (not shown) so that the host computer (not shown) controls the display (not shown) to display the encoding array (i.e., standard encoding array) of the qualified electrode sheet 110 and the encoding array (i.e., test encoding array) of the tested electrode sheet 110' of the same batch and specification as the qualified electrode sheet 110.

[0115] Step 2: Power on the electric field generator 130 to provide DC power VCC to the temperature detection unit 113 of the qualified electrode sheet 110 for temperature detection. The adapter 120 obtains a set of standard encoding array A according to the aforementioned encoding rules. The standard encoding array A is routed from the adapter 120 to the aforementioned electric field generator 130 to the host computer (not shown) and finally stored in the host computer (not shown) as a standard encoding array for comparison.

[0116] Step 3: Provide a test electrode 110' of the same batch and specification as the qualified electrode 110, connect the test electrode 110' to the aforementioned adapter 120, and the aforementioned adapter 120 obtains a set of test code array B according to the aforementioned coding rules. The test code array B is routed from the aforementioned adapter 120 to the aforementioned electric field generator 130 to the host computer (not shown) and displayed on the display (not shown).

[0117] Step 4: The host computer (not shown) compares the test code array B with the standard code array A for consistency judgment. If the test code array B is consistent with the standard code array A, proceed to step 5; if the test code array B is inconsistent with the standard code array A, proceed to step 6.

[0118] Step 5: The display (not shown) shows that the test electrode 110' is "qualified", and the test electrode 110' is placed in the good product area. Then, repeat steps 3 to 4 to test the next test electrode 110'.

[0119] Step Six: The display (not shown) shows that the tested electrode 110' is "unqualified". The tested electrode 110' is placed in the defective product area. Then, steps three and four are repeated to test the next tested electrode 110'.

[0120] In the above step six, while the display (not shown) shows that the tested electrode 110' is "unqualified", the host computer (not shown) can also control the alarm (not shown) to sound an alarm, so as to warn the operator that the tested electrode 110' is "unqualified" and needs to be placed in the defective product area. The alarm (not shown) can be a sound alarm, a light alarm, etc. Manual 23 / 27 pages 26 CN 121265986 A

[0121] It should be noted that through the above quality inspection steps of electrode 110, the standard code arrays of various qualified electrode 110s can be stored in the host computer (not shown) to form a standard code array library of qualified electrode 110s. When there are similarWhen the same type of electrode sheet 110' is tested again, the corresponding standard code array A in the standard code array library can be called as the comparison code for the batch of electrode sheets 110' to be tested, and compared with the test code array B corresponding to the electrode sheet 110' to determine whether the batch of electrode sheets 110' is qualified.

[0122] The code combination of the standard code array A and the corresponding test code array B of the electrode sheet 110' in the above steps is composed of multiple bits of code, and is not limited to the 20-bit code combination corresponding to the electrode sheet 110 in the embodiment of Figure 2. It can be composed of 13-bit, 24-bit, etc. code arrangement combination.

[0123] The above steps are described with the adapter 120 for quality testing of the electrode sheet 110 as an example. The quality testing of the electrode sheet 110 can also be performed by the electric field generator 130. In addition, the number of electrode sheets 110 that the adapter 120 can connect to, the number of electrode units 112 in each electrode sheet 110, and the setting of the sampling code are all exemplary descriptions and are not intended to limit this application.

[0124] It should be noted that in this embodiment, the control switch 124, which is electrically connected to the multiple grounding lines 118 of the electrode 110, and the bidirectional switching switch 125, which is electrically connected to the multiple dual-purpose signal lines 119 of the electrode 110, are both located in the adapter 120. However, in other embodiments, the control switch 124, which is electrically connected to the grounding lines 118, and the bidirectional switching switch 125, which is electrically connected to the dual-purpose signal lines 119, may also be located on the electrode 110 or in the electric field generator 130, which will not be described in detail here. In addition, the ADC unit 122 located in the adapter 120 may also be located in the electric field generator 130 and directly controlled by the second controller 131.

Therefore, the adapter 220 has five control switches 224 to connect five grounding wires 218 respectively; and four bidirectional switching switches 225 to connect four dual-purpose signal lines 219 respectively.

Unlike the tumor electric field therapy system 100 of the first embodiment shown in Figure 1, in terms of spatial structure, the multiple electrode units 312 of the electrode sheet 310 of this embodiment are connected symmetrically.Row connections, for example, adjacent electrode units 312 in the four electrode units 312 located in the first row and third column, the second row and third column, the third row and third column, and the fourth row and third column are connected by a column-direction connecting strip. At the same time, adjacent electrode units 312 in the four electrode units 312 located in the first row and fourth column, the second row and fourth column, the third row and fourth column, and the fourth row and fourth column are also connected by a column-direction connecting strip.
