Description

Technical Field

[0001] This application relates to tumor electric field therapy technology, and more particularly to an electrode sheet and a tumor electric field therapy system. Background Technology

[0002] Tumor electric field therapy uses low-intensity, medium- to high-frequency alternating electric fields to inhibit the formation of spindle microtubules during mitosis in certain tumor cells, suppress the separation of intracellular organelles during cell division, and induce apoptosis in mitotic cells, thereby achieving the therapeutic effect on tumors.

[0003] Compared to traditional cancer treatments, tumor electric field (TEF) therapy has an innovative mechanism of action. Certain physiological characteristics of tumor cells, such as their geometry and high-frequency mitosis, make them susceptible to TEF. TEF therapy disrupts the normal aggregation of tubulin by applying directional forces to intracellular polar particles (such as macromolecules and organelles). These processes can lead to physical damage to the cell membrane and apoptosis. During the telophase of mitosis, the morphology of the cleavage groove leads to an uneven distribution of the electric field around it. Under the influence of TEF, the electric field strength at the cleavage groove is significantly enhanced, causing charged substances in the cell to migrate towards the cleavage groove, interfering with or even destroying cell structure formation, ultimately leading to cell division failure and apoptosis.

[0004] Currently, tumor electric field therapy (TEF) systems mainly consist of 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 alternating electrical signals for TGF therapy to each electrode pad via the adapter, and then applies an alternating electric field to the patient's tumor site for TGF therapy. Because tumors are distributed in different locations, the intensity and coverage of the electric field vary depending on the location of the tumor. For example, when the tumor is in the head, the electric field coverage is not very large, and two pairs of electrode pads with nine electrode units are sufficient. When the tumor is in the chest or abdomen, the electric field coverage is larger than that of the head, requiring more electrode units, such as electrode pads with 13, 20, or more than nine electrode units.

[0005] During tumor electric field therapy, the electric field applied to the patient generates heat at the corresponding locations on the skin where the electrode pads are applied. To prevent low-temperature burns, a temperature sensor is required at each electrode unit to monitor the skin surface temperature. Depending on the location of the tumor and the area to be covered by the tumor electric field therapy, there are situations where two pairs of electrode pads with different numbers of electrode units need to be used together. Correspondingly, the number of temperature sensors required for electrode pads with different numbers of electrode units also differs. For example, electrode pads with 9, 13, and 20 electrode units all require different numbers of temperature sensors, and the adapter needs to collect analog temperature signals from these 9, 13, and 20 temperature sensors respectively.

[0006] In related technologies, adapters use the same acquisition program to collect analog temperature signals from the temperature sensors on their connected electrode plates. However, this can lead to interference with the analog temperature signals or the inability to acquire some temperature sensors. For example, if an adapter acquires 20 temperature sensors from a pair of electrode plates with 20 electrode units using the same acquisition program, it will obtain 40 analog temperature signals. If the adapter uses the same acquisition program to acquire temperature sensors from a pair of electrode plates with 13 electrode units, it will also acquire 40 analog temperature signals. Of these 40 signals, only 26 are from the temperature sensors on the 13-electrode-unit electrode plates; the other 14 are interference signals. However, the adapter cannot identify which analog temperature signals are the desired signals. If the adapter collects temperature sensors from a pair of electrode plates with 13 electrode units and a pair of electrode plates with 20 electrode units connected to it according to the acquisition program for collecting 13 temperature sensors, then all temperature sensors on the electrode plates with 13 electrode units can be acquired by the adapter, but 7 temperature sensors on the electrode plates with 20 electrode units will not be acquired by the adapter. Utility Model Content

[0007] This application aims to at least partially solve one of the technical problems in the related art. Therefore, the first objective of this application is to provide an electrode sheet.

[0008] The second objective of this application is to propose a tumor electric field therapy system that can control multiple electrode units in zones using fewer conductive traces. This not only improves the efficacy of tumor electric field therapy but also facilitates electrode application. Furthermore, the type of electrode can be determined based on temperature detection signals.

[0009] To achieve the above objectives, a first aspect of this application provides an electrode pad for use in a tumor electric field therapy system. The tumor electric field therapy system includes a switching unit and a control switch. The electrode pad includes: a substrate; multiple electrode units and multiple temperature detection units disposed on the substrate; each electrode unit is capable of applying an alternating electrical signal; each temperature detection unit corresponds to one electrode unit; wherein the multiple electrode units are configured into at least two row groups and at least two column groups; the grounding terminals of each temperature detection unit in each row group are connected to a grounding pin via a control switch; the signal terminals of each temperature detection unit in each column group are short-circuited to their respective electrode units and then connected via a common path. A dual-purpose signal line is connected to the switching unit to switch the dual-purpose signal line to either a temperature sampling point or an alternating power supply line. When the dual-purpose signal line is connected to the temperature sampling point, the on / off state of the control switch is configured so that the analog temperature signal detected by the corresponding temperature detection unit in each row group is sampled based on the temperature sampling point. The sampled analog temperature signal detected by each temperature detection unit is used to characterize the encoding array of the corresponding electrode sheet, and the encoding array is used to characterize the type of the corresponding electrode sheet. When the dual-purpose signal line is connected to the alternating power supply line, the electrode unit of at least one column group is subjected to the alternating electrical signal based on the alternating power supply line.

[0010] To achieve the above objectives, a second aspect of this application provides a tumor electric field therapy system, comprising: at least one pair of the aforementioned electrode pads; a control switch configured to connect the grounding terminals of each temperature detection unit in each row group in series to a grounding pin via a grounding line; and a switching unit configured to switch the dual-purpose signal line to either a temperature sampling point or an alternating power line, such that when the dual-purpose signal line is connected to the temperature sampling point, the on / off state of the control switch is configured to allow the analog temperature signal detected by the corresponding temperature detection unit in each row group to be sampled based on the temperature sampling point, wherein the sampled analog temperature signal detected by each temperature detection unit is used to characterize an encoding array of the corresponding electrode pad, the encoding array being used to characterize the type of the corresponding electrode pad; and when the dual-purpose signal line is connected to the alternating power line, at least one electrode unit in the column group is subjected to the alternating electrical signal based on the alternating power line.

[0011] According to the tumor electric field therapy system of this application embodiment, for each electrode sheet, multiple electrode units are divided into multiple row groups and multiple column groups. The grounding terminals of the temperature detection units corresponding to each electrode unit in each row group are connected to a grounding pin via a control switch. The signal terminals of the temperature detection units corresponding to each electrode unit in each column group are short-circuited with their respective electrode units and then connected to a switching unit via a dual-purpose signal line. The switching unit is configured to switch the dual-purpose signal line to either a temperature sampling point or an alternating power supply line. This allows the control switch to be configured to allow the analog temperature signal detected by the corresponding temperature detection unit in each row group to be sampled based on the temperature sampling point when the dual-purpose signal line is connected to the temperature sampling point, and vice versa. In the case of a power line, at least one column of electrode units is subjected to an alternating electrical signal based on the alternating power line. Thus, temperature sampling and alternating electrical signal application can be achieved through a dual-purpose signal line. This not only avoids the addition of new AC signal lines (i.e., AC lines) but also eliminates the need for existing AC signal lines. As a result, multiple electrode units can be controlled in zones using fewer conductive traces, which not only improves the effect of tumor electric field therapy but also facilitates electrode patch application. At the same time, the simulated temperature signal detected by each sampled temperature detection unit is used to characterize the corresponding electrode patch's encoding array. The encoding array is used to characterize the type of the corresponding electrode patch. In this way, the type of electrode patch can be automatically identified, thereby enabling temperature acquisition of different types of electrode patches without missing any data or generating interference signals.

Detailed Implementation

[0029] The embodiments of the technical solution of this application will now be described in detail with reference to the accompanying drawings. These embodiments are only used to more clearly illustrate the technical solution of this application and are therefore merely examples, and should not be used to limit the scope of protection of this application.

[0030] Some embodiments:

[0031] Figure 1 The diagram shown is a schematic representation of a tumor electric field therapy system 100 according to the first embodiment of this application. Figure 1As shown, the tumor electric field therapy system 100 includes: at least one pair of electrode pads 110, an adapter 120 electrically connected to the at least one pair of electrode pads 110, and an electric field generator 130 electrically connected to the adapter 120. The at least one pair of electrode pads 110 can be disposed in pairs on the patient's body surface, such as... Figure 1 The device comprises four electrode pads 110, with each pair of electrode pads 110 positioned on the patient's body surface. An electric field generator 130 supplies power to at least one pair of electrode pads 110, generating an alternating electric field between the at least one pair of electrode pads 110 for tumor treatment. An adapter 120 is electrically connected between the at least one pair of electrode pads 110 and the electric field generator 130, transmitting the alternating electrical signal generated by the electric field generator 130 to the at least one pair of electrode pads 110. In other words, the electric field generator 130 generates an alternating electrical signal, which is transmitted through the adapter 120 to each electrode pad 110, thereby generating an alternating electric field between the same pair of electrode pads 110 for tumor treatment, thus applying the alternating electric field to the patient's tumor site for tumor therapy.

[0032] like Figure 1 As shown, in this embodiment, there are four electrode pads 110, each electrode pad 110 including the same number of electrode units 112, each electrode unit 112 being electrically connected to the adapter 120, and each electrode pad 110 having 20 electrode units 112. In other embodiments, the tumor electric field therapy system 100 may have more or fewer electrode pads 110; in other 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 other embodiments, the number of electrode units 112 on each electrode pad 110 may be 9, 13, 19, etc.

[0033] Figure 2 for Figure 1 The diagram shows the circuit connection between the electrode pad 110 and the adapter 120 of the tumor electric field therapy system 100. It is worth noting that: Figure 2 The arrangement of the electrode units 112 shown is to more clearly illustrate the electrical connection between an electrode piece 110 and the adapter 120. Figure 2 The arrangement of electrode units 112 shown does not represent their spatial arrangement. (Combined with...) Figure 1 and Figure 2The electrode sheet 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 has multiple conductive traces embedded in it, 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 ground lines 118 and the multiple dual-purpose signal lines 119 of the substrate 111 in a one-to-one correspondence. In this embodiment, the total number of ground lines 118 and dual-purpose signal lines 119 embedded in the substrate 111 does not exceed nine, therefore the number of wires in the first cable 116 does not exceed nine.

[0034] 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, which are grouped 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. The electrode units 112 and the temperature detection units 113 are both soldered to the substrate 111, and the signal terminal 113B of the electrode unit 112 and the corresponding temperature detection unit 113 are shorted. Since the multiple temperature detection units 113 are arranged in a one-to-one correspondence with the multiple electrode units 112, the multiple temperature detection units 113 are also arranged in four rows and five columns in the circuit connection. It should be noted that the arrangement shown here is to more clearly illustrate the electrical connection between the electrode plate 110 and the adapter 120, and does not represent the spatial arrangement of the electrode unit 112. Its spatial structure may be as follows: Figure 1The generally array-like structure shown can also be other structures, such as petal-shaped or scattering-shaped, and can be regular or irregular. In some other embodiments, the 20 electrode units 112 can also be arranged in other ways. Of course, in some other embodiments, the electrode sheet 110 can 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. The electrode units 112 are configured to apply alternating electrical signals to the tumor site of the patient. The temperature detection unit 113 is configured to detect the temperature of the patient's body surface that is in contact with the electrode sheet 110, that is, the temperature at the corresponding electrode unit 112, and output the temperature detection signal to an external device such as an adapter 120. In this embodiment, the multiplexed signal lines 119 of the substrate 111 are respectively arranged in a one-to-one correspondence with the multiple columns of electrode units 112, and are configured to transmit the alternating electrical signals generated by the electric field generator 130 to each electrode unit 112 in the corresponding column. That is, electrode units 112 located in the same column are all short-circuited through the same dual-purpose signal line 119 of the substrate 111, and electrode units 112 located in different columns are connected in parallel through different dual-purpose signal lines 119 of the substrate 111. The dual-purpose signal line 119 of the substrate 111 is electrically connected to the first cable 116, and then electrically connected to the electric field generator 130 via the adapter 120. Furthermore, the dual-purpose signal line 119 of the substrate 111 receives the alternating electrical signal generated by the electric field generator 130 through the first cable 116 and the adapter 120.

[0035] Multiple grounding lines 118 are respectively configured to correspond one-to-one with multiple rows of electrode units 112, and are used to sequentially short-circuit and ground each temperature detection unit 113 in each row. That is, the grounding terminals 113A of multiple temperature detection units 113 located in the same row 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 rows are respectively connected in parallel through different grounding lines 118 of the substrate 111. During the temperature detection period, only one of the multiple grounding lines 118 is conducting at any given time, and the rest are disconnected.

[0036] Each of the multiplexed dual-purpose signal lines 119 is further configured to short-connect 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 output of duplicate signals from the dual-purpose signal lines 119. Specifically, 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 that 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 a 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 that row group. In this embodiment, the external device used to receive the detection signal is an adapter 120. The signal terminals 113B of the multiple temperature detection units 113 located in different columns are connected in parallel through different dual-purpose signal lines 119 of the substrate 111. The signal terminals 113B of the multiple temperature detection units 113 located in the same column are all shorted to the same dual-purpose signal line 119 of the substrate 111.

[0037] 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 that would complicate cable fixation; simultaneously, it prevents an increase in the number of wires in the first cable 116 from affecting the adhesion between the electrode pad 110 and the corresponding body surface of the patient's tumor site. The substrate 111 contains a total of 9 embedded grounding wires 118 and dual-purpose signal lines 119. Specifically, in this embodiment, the substrate 111 contains 4 embedded grounding wires 118 and 5 embedded dual-purpose signal lines 119. The number of conductive lines electrically connected to the grounding wires 118 of the electrode pad 110 in the tumor electric field therapy system 100 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. In the tumor electric field therapy system 100, the number of conductive lines electrically connected to the dual-purpose signal lines 119 of the electrode pads 110 is related to the number of columns N of the electrode units 112, and is greater than or equal to the number of columns N of the electrode units 112, where N is a positive integer. The number of lines L embedded in the substrate 111 of the electrode pads 110 is equal to the sum of the number of grounding lines 118 and the number of dual-purpose signal lines 119. In this embodiment, the number of grounding lines 118 is equal to the number of rows M of the electrode units 112; the number of dual-purpose signal lines 119 is equal to the number of columns N of the electrode units 112.

[0038] In terms of spatial structure, multiple electrode units 112 are arranged in a roughly two-dimensional array on the substrate 111 at intervals. For example... Figure 1 As shown, 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. The first and fourth rows each have four electrode units 112, and the second and third rows each have six electrode units 112. The four electrode units 112 in each of the first and fourth rows are located in each of the second to fifth columns, and the six electrode units 112 in each of the second and third rows are located in each of the first to sixth columns.

[0039] like Figure 1As shown, in terms of spatial structure, multiple electrode units 112 are connected in an asymmetrical manner. For example, electrode units 112 located in the first row, third column, second row, third row, third column, and fourth row, third column are connected by a column-oriented connecting strip (unlabeled), and electrode units 112 located in the first row, fifth column, second row, fifth column, third row, and fourth row, fifth column are also connected by a column-oriented connecting strip (unlabeled). Each electrode sheet 110 has a free end. For example, at least one electrode unit 112 among the multiple electrode units 112 is connected to at most one other electrode unit 112. For example, electrode units 112 located in the first row, second column, second row, first column, third row, and fourth row, second column have no connecting strips in the column direction, thus forming an open space (unlabeled). This open space (unlabeled) is adjustable. For example, the position of the electrode unit 112 in the first row, second column is movable relative to the positions of the electrode units 112 in the second row, first column, and second row, second column. The positions of the electrode units 112 in the second row and second column of the third row are movable relative to the positions of the electrode units 112 in the first column of the third row and second column of the third row. The positions of the electrode units 112 in the first column of the third row and second column of the third row are movable relative to the positions of the electrode units 112 in the second column of the fourth row. This allows the open space (unlabeled) between the electrode units 112 in the corresponding rows to be adjusted when the electrode pad 110 is applied to the patient's body surface. This increases the heat dissipation space of the corresponding electrode units 112, thereby accelerating heat dissipation. It also allows the patient to adjust the position of the electrode units 112 based on the fever. Similarly, the electrode units 112 located in the first row, fourth column, second row, fourth column, second row, sixth column, third row, fourth column, third row, sixth column, and fourth row, fourth column have no connecting strips in the column direction, thus forming open spaces (unlabeled). These open spaces (unlabeled) are adjustable. For example, the position of the electrode unit 112 in the first row, fourth column is movable relative to the position of the electrode unit 112 in the second row, fourth column is movable relative to the position of the electrode unit 112 in the third row, fourth column is movable relative to the position of the electrode unit 112 in the second row, sixth column is movable relative to the position of the electrode unit 112 in the third row, fourth column is movable relative to the position of the electrode unit 112 in the third row, fourth column is movable relative to the position of the electrode unit 112 in the fourth row, fourth column. Thus, when the electrode pad 110 is applied to the patient's body surface, the open spaces (unlabeled) between the electrode units 112 in the corresponding rows can be adjusted. This increases the heat dissipation space of the corresponding electrode units 112, thereby accelerating heat dissipation and allowing the patient to adjust the position of the electrode units 112 based on their fever status.

[0040] Each electrode unit 112 can be subjected to an alternating electrical signal, thereby enabling the paired electrode sheets 110 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 materials. 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 located 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. Specifically, 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 ground terminal 113A of the temperature detection unit 113. The signal terminal 114B of the temperature sensor 114 serves as the signal terminal 113B of the temperature detection unit 113. The temperature sensor 114 can be a thermistor or other temperature sensor. Each temperature sensor 114 is associated with a corresponding diode 115. The diode 115 is connected in series with the temperature sensor 114 of the same electrode unit 112. It can prevent reverse current flow to prevent detection signals from other electrode units 112 from affecting the temperature sensor 114.

[0041] like Figure 2As shown, the electrode sheet 110 in this embodiment includes four grounding wires 118, each grounding wire 118 being used to ground the grounding 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 the electrode sheet 110, the first row group includes electrode units 112-1 to 112-5, the second row group includes electrode units 112-6 to 112-10, the third row group includes electrode units 112-11 to 112-15, and the fourth row group includes electrode units 112-16 to 112-20. Specifically, the first grounding wire 118-1 is used to ground each temperature detection unit 113 corresponding to electrode unit 112-1 to electrode unit 112-5 in the first row group; the second grounding wire 118-2 is used to ground each temperature detection unit 113 corresponding to electrode unit 112-6 to electrode unit 112-10 in the second row group; the third grounding wire 118-3 is used to ground each temperature detection unit 113 corresponding to electrode unit 112-11 to electrode unit 112-15 in the third row group; and the fourth grounding wire 118-4 is used to ground each temperature detection unit 113 corresponding to electrode unit 112-16 to electrode unit 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 terminals 113A of the temperature detection units 113 corresponding to each electrode unit 112 in each row group are connected to the grounding pin through a single 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 short, each grounding wire 118 short-circuits and grounds the grounding terminals 113A of all the temperature detection units 113 corresponding to all the electrode units 112 in the corresponding row group.

[0042] like Figure 2As shown, the electrode sheet 110 in this embodiment also includes five dual-purpose signal lines 119. One end of each dual-purpose signal line 119 is connected to the signal terminal 113B of each electrode unit 112 and the corresponding temperature detection unit 113 in each row group, and the other end is connected to an 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 the signal terminal 113B of one electrode unit 112 and the corresponding temperature detection unit 113, or not connected to the signal terminal 113B of any electrode unit 112 and the corresponding temperature detection unit 113 in that row group, so as 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 terminals 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 terminals 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, four electrode units 112 (112-18) and their corresponding temperature detection units 113 have their signal terminals 113B connected simultaneously; one end of the fourth dual-purpose signal line 119-4 is connected to the signal terminals 113B of 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 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 the same column group 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 coordinating with the closing or opening of the grounding wire 118.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. Each bidirectional switching switch 125 is configured to switch the dual-purpose signal line 119 to either the temperature sampling point (unlabeled) or the alternating power supply line 127, so that when the dual-purpose signal line 119 is connected to the temperature sampling point (unlabeled), the control switch 124 can be configured to... The switching state causes the temperature detection signal detected by the corresponding temperature detection unit 113 in each row group to be sampled based on the temperature sampling point (unlabeled). The temperature detection signal detected by each sampled temperature detection unit 113 is used to determine the encoding array of the corresponding electrode piece 110. The type of the corresponding electrode piece 110 is determined by the encoding array. When the dual-use signal line 119 is connected to the alternating power line 127, at least one column group of electrode units 112 is given an alternating electrical signal based on the alternating power line 127, which will be described in detail below.

[0043] The multi-path grounding line 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 line 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.

[0044] 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.

[0045] refer to Figure 2 and Figure 3As shown, the adapter 120 includes: a first controller 121, multiple ADC units 122 connected to the first controller 121, multiple voltage-reducing resistors 123 and multiple control switches 124 corresponding to each of the multiple ADC units 122, multiple bidirectional switching switches 125 corresponding to each of the multiple ADC units 122, a first communication unit 126, an alternating power supply line 127 corresponding to each of the bidirectional switching switches 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 through the first cable 116 of the corresponding electrode plate 110. 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 M and columns N of the electrode units 112 of the electrode piece 110 plus 1; 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 + 1). 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 the number of groups of bidirectional switching switches 125 are both 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.

[0046] Each group of control switches 124 has multiple control switches 124, which are respectively connected to the adapter 120 and electrically connected to the circuit lines (unlabeled) corresponding one-to-one with the multiple grounding lines 118 of a corresponding electrode piece 110, and are configured to control the conduction or disconnection of the multiple grounding lines 118. The circuit lines (unlabeled) that are each electrically connected to the multiple grounding lines 118 of the electrode piece 110 are grounded to GND at the end closest to the control switch 124. The number of control switches 124 in each group of control switches 124 is related to the number of grounding lines 118 on the substrate 111 of the corresponding electrode piece 110; in this embodiment, the two are equal. Figure 2 As shown, in this embodiment, the multiple 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 each control the closing or opening of the corresponding grounding wire 118 of the same electrode plate 110. 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, from electrode unit 112-1 to electrode unit 112-5; 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, from electrode unit 112-6 to electrode unit 112-10; the second control switch 124-1 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 third control switch 124-1 is used to control the opening or closing of the first grounding wire 118-1 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 third 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 The third control switch 124-3 is used to control the opening or closing of the third grounding wire 118-3 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 third row of the electrode plate 110 (electrode units 112-11 to 112-15). The fourth control switch 124-4 is used to control the opening or closing of the fourth grounding wire 118-4 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 fourth row of the electrode plate 110 (electrode units 112-16 to 112-20). The control switches 124 can be mechanical switches, such as relays. The control switches 124 can also be electronic switches, and each control switch 124 can be opened and closed by an additional first controller 121.

[0047] 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, thereby sequentially and individually activating each grounding wire 118 of the corresponding electrode pad 110 and coordinating with the switching of the corresponding bidirectional switching switch 125 to collect the patient's body surface temperature detected by all temperature detection units 113 on the electrode pad 110. The number of control switches 124 in each set is not less than the number of grounding wires 118 on the substrate 111 of the corresponding electrode pad 110. In this embodiment, the number of control switches 124 in each set is the same as the number of grounding wires 118 on the corresponding electrode pad 110.

[0048] Each group of bidirectional switching switches 125 has multiple bidirectional switching switches 125. The multiple bidirectional switching switches 125 in each group are respectively connected to the adapter 120 and electrically connected to the circuit lines (unlabeled) corresponding to the multi-purpose signal lines 119 of a corresponding electrode plate 110. The number of bidirectional switching switches 125 in each group is related to the number of multi-purpose signal lines 119 on the substrate 111 of the corresponding electrode plate 110, and is greater than or equal to the number of multi-purpose signal lines 119 on the substrate 111 of the corresponding electrode plate 110; in this embodiment, both are equal. Each bidirectional switching switch 125 has two ends labeled 1 and 2. End 1 of the multiple bidirectional switching switches 125 in the same group is electrically connected to the corresponding detection channels in the multiple detection channels of the corresponding group of ADC units 122 through temperature sampling points (unlabeled). End 2 of each bidirectional switching switch 125 in the same group is electrically connected to the corresponding AC power line 127. Each bidirectional switching switch 125 is configured to control the multiplexer signal line 119 to connect to the corresponding alternating power supply line 127 to transmit alternating electrical signals or to the corresponding detection channel of the corresponding ADC unit 122 to receive the temperature detection signal output by the temperature detection unit 113.

[0049] like Figure 2As shown, taking the electrical connection of one electrode 110 with the adapter 120 as an example, in this embodiment with 20 electrode units 112, the multiple bidirectional switches 125 are respectively the first bidirectional switch 125-1, the second bidirectional switch 125-2, the third bidirectional switch 125-3, the fourth bidirectional switch 125-4, and the fifth bidirectional switch 125-5. The multiple bidirectional switches 125 in the same group each control the switching of a corresponding dual-purpose signal line 119 of the same electrode 110 between transmitting alternating electrical signals and transmitting temperature detection signals. Specifically, the first bidirectional switching switch 125-1 is used to control the switching of the first dual-purpose signal line 119-1 of the corresponding electrode sheet 110 between transmitting alternating electrical signals and transmitting temperature detection signals, thereby controlling the conduction of each electrode unit 112 in the first column group of electrode units 112-1, 112-6, 112-11, and 112-16 of the electrode sheet 110, and controlling the conduction of each electrode unit 112 in the first column group of electrode units 112-1, 112-6, 112-11, and 112-16. The switching between the conduction of the signal terminals 113B of each temperature detection unit 113 and the corresponding first control switch 124-1, second control switch 124-2, third control switch 124-3, and fourth control switch 124-4, in conjunction with these switches, enables the first row of electrode units 112-1, 112-6, 112-11, and 112-16 to transmit alternating electrical signals to the patient or to output temperature detection signals collected by the temperature detection units 113 corresponding to these electrode units 112 to the corresponding ADC unit 122. The second bidirectional switching switch 125-2 is used to control the switching of the second dual-purpose signal line 119-2 of the corresponding electrode plate 110 between transmitting alternating electrical signals and transmitting temperature detection signals, thereby controlling the conduction of each electrode unit 112 in the second column group of the electrode plate 110 (electrode unit 112-2, electrode unit 112-7, electrode unit 112-12, and electrode unit 112-17) and the corresponding electrode units 112-2, 112-7, 112-12, and 112-17 in the second column group. The switching between the conduction of the signal terminal 113B of each temperature detection unit 113 and the switching between the two, and in conjunction with the corresponding first control switch 124-1, second control switch 124-2, third control switch 124-3, and fourth control switch 124-4, enables the second row of electrode units 112-2, 112-7, 112-12, and 112-17 to transmit alternating electrical signals to the patient or to output temperature detection signals collected by the temperature detection units 113 corresponding to these electrode units 112 to the corresponding ADC unit 122;The third bidirectional switching switch 125-3 is used to control the switching of the third dual-purpose signal line 119-3 of the corresponding electrode plate 110 between transmitting alternating electrical signals and transmitting temperature detection signals, thereby controlling the conduction of each electrode unit 112 in the third column group of the electrode plate 110 (electrode unit 112-3, electrode unit 112-8, electrode unit 112-13, and electrode unit 112-18) and the corresponding electrode units 112-3, 112-8, 112-13, and 112-18 in the third column group. The switching between the conduction of the signal terminal 113B of each temperature detection unit and the switching between the two, and in conjunction with the corresponding first control switch 124-1, second control switch 124-2, third control switch 124-3, and fourth control switch 124-4, enables the third row of electrode units 112-3, 112-8, 112-13, and 112-18 to transmit alternating electrical signals to the patient or output temperature detection signals collected by the temperature detection units 113 corresponding to these electrode units 112 to the corresponding ADC unit 122; The four-way bidirectional switch 125-4 is used to control the switching of the fourth dual-purpose signal line 119-4 of the corresponding electrode plate 110 between transmitting alternating electrical signals and transmitting temperature detection signals, thereby controlling the conduction of each electrode unit 112 in the fourth column group of electrode units 112-4, 112-9, 112-14, and 112-19 of the electrode plate 110, and the corresponding electrode units 112-4, 112-9, 112-14, and 112-19 in the fourth column group. The switching between the conduction of the signal terminal 113B of the temperature detection unit 113 and the corresponding first control switch 124-1, second control switch 124-2, third control switch 124-3, and fourth control switch 124-4, enables the fourth row of electrode units 112-4, 112-9, 112-14, and 112-19 to transmit alternating electrical signals to the patient or output temperature detection signals collected by the temperature detection unit 113 corresponding to these electrode units 112 to the corresponding ADC unit 122;The fifth bidirectional switching switch 125-5 is used to control the switching of the fifth dual-purpose signal line 119-5 of the corresponding electrode plate 110 between transmitting alternating electrical signals and transmitting temperature detection signals, thereby controlling the conduction of each electrode unit 112 in the fifth column group of the electrode plate 110 (electrode units 112-5, 112-10, 112-15, and 112-20) and the corresponding electrode units 112-5, 112-10, 112-15, and 112-20 in the fifth column group. The switching between the conduction of the signal terminal 113B of each temperature detection unit 113 and the switching between the two, and in conjunction with the corresponding first control switch 124-1, second control switch 124-2, third control switch 124-3, and fourth control switch 124-4, enables the fifth column of electrode units 112-5, 112-10, 112-15, and 112-20 to transmit alternating electrical signals to the patient or output temperature detection signals collected by the temperature detection units 113 corresponding to these electrode units 112 to the corresponding ADC unit 122. When all control switches 124 are open and both ends of each bidirectional switch 125 are closed (end 2 is on, end 1 is off), alternating electrical signals can be transmitted to each electrode unit 112 of the corresponding electrode plate 110. When end 1 of each bidirectional switch 125 is on and end 2 is off, it can cooperate with each control switch 124 in the corresponding control switch group to transmit, in a time-division manner, the temperature detection signals collected by the temperature detection unit 113 corresponding to each electrode unit 112 on the electrode plate 110. The bidirectional switch 125 can be a mechanical switch, such as a relay. The bidirectional switch 125 can also be an electronic switch, and each bidirectional switch 125 can be switched by the first controller 121.

[0050] In this embodiment, all of the multiple 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 switching of multiple bidirectional switching switches 125 in each set between their respective terminals 1 and 2, and to cooperate with the closing or opening of the corresponding control switch 124, so as 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.

[0051] 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 an analog signal to a digital signal. Each ADC unit 122 includes multiple detection channels A, B, C, D, and E, and each detection channel A, B, C, D, and E is used to connect to one corresponding dual-purpose signal line 119 in the multi-channel dual-purpose signal line 119 through the corresponding bidirectional switching switch 125. Figure 2 As shown, each ADC unit 122 contains five detection channels A, B, C, D, and E, which are respectively the first detection channel A, the second detection channel B, the third detection channel C, the fourth detection channel D, and the fifth detection channel E. The first detection channel A is connected to the first 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.

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 sheet 110 according to the received digital signals. For example, when any of the received digital signals exceeds a preset threshold, it indicates that the temperature detected by the temperature detection unit 113 corresponding to at least one electrode unit 112 in the electrode sheet 110 exceeds a preset temperature threshold (e.g., 41°C, 42°C, etc.). At this time, the voltage or current of the alternating electrical signal output by the electric field generator 130 can be appropriately reduced to avoid the electrode unit 112 of the electrode sheet 110 from becoming too hot when the alternating electrical signal is applied, which could cause 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 the digital signals converted by the multiple ADC units 122. In this embodiment, the preset temperature threshold can be a value within the range of 36℃-45℃.

The second communication unit 135 is electrically connected to the wire 5 of the second connector 150 through its data receiving line RX and to the wire 6 of the second connector 150 through its data transmitting line TX, thereby enabling information exchange between the electric field generator 130 and the adapter 120. The second controller 131 is also electrically connected to the second communication unit 135, the AC signal generator 132, and a set of power switches 133. The second controller 131 is configured to control the opening and closing of each power switch 133 in the set of power switches 133 and to adjust relevant parameters of the alternating electrical signal applied by the AC signal generator 132 based on relevant digital signals received from the adapter 120 by the second communication unit 135.

The AC signal generator 132 is electrically connected to this group of power supply switches 133 via multiple AC power lines 134. Specifically, the number of power supply switches 133 in the electric field generator 130 is related to the number of electrode plates 110. In this embodiment, the number of power supply switches 133 is equal to the number of electrode plates 110, and both are four.

[0056] The following will refer to Figures 2 to 4 The working principle of the tumor electric field therapy system 100 in this embodiment is described in detail.

[0057] 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 in a time-division manner. At this time, the temperature detection signals collected by each temperature detection unit 113 corresponding to each electrode unit 112 in each row of the electrode plate 110 can be collected sequentially in a time-division manner through the multiple detection channels A, B, C, D, E of the ADC unit 122 corresponding to the electrode plate 110. Each detection channel A, B, C, D, and E of each ADC unit 122 in each row simultaneously acquires only the temperature detection signals of the temperature detection units 113 corresponding to the electrode units 112 in the same row of the electrode plate 110. These temperature detection signals can be characterized by voltage values. Only one of the four control switches 124 in the group corresponding to the electrode plate 110 can be on at any given time, while the other three are off. All five bidirectional switches 125 in the group corresponding to the ADC unit 122 are switched to their respective terminals to ensure that each dual-purpose signal line 119 of the electrode plate 110 is electrically connected to the corresponding detection channels A, B, C, D, and E of the ADC unit 122. 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 of the electrode plate 110 that are shorted by a grounding wire 118 corresponding to the on control switch 124.

[0058] Specifically, when the first control switch 124-1 is closed, and the second control switch 124-2, the third control switch 124-3, and the fourth control switch 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, while the temperature detection units 113 corresponding to electrode units 112-6 to 112-20 in the other row groups are de-energized. In this group of ADC units 122, the temperature detection units 113 corresponding to electrode units 112-1, 112-6, 112-11, and 112-16 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 112-1 is grounded at signal terminal 113B, while the grounding terminals 113A of the temperature detection units 113 corresponding to electrode units 112-6, 112-11, 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, the other temperature detection units 113 in the same row group will 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) collected 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 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 unit 112-2. 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 unit 112-3. 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 unit 112-4. The voltage value acquired on the fifth detection channel E of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-5.

[0059] When the second control switch 124-2 is closed, the first control switch 124-1, the third control switch 124-3, and the fourth control switch 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 in the second row group are energized, and the temperature detection units 113 corresponding to electrode units 112-1 to 112-5 and electrode units 112-11 to 112-20 in the other rows are de-energized. 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 in this group are short-circuited. Since only the grounding terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-6 is grounded, while the grounding terminals 113A of the temperature detection units 113 corresponding to electrode units 112-1, 112-11, 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, the other temperature detection units 113 in the same row group will not affect the resistance value of the temperature detection unit 113 corresponding to electrode unit 112-6. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-6 is effectively operating on the first detection channel A of the ADC unit 122 in this group. 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 112-6. 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 unit 112-7. 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 unit 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 unit 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 unit 112-10.

[0060] When the third control switch 124-3 is closed, the first control switch 124-1, the second control switch 124-2, and the fourth control switch 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, and 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. 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 in this group are short-circuited. Since only the grounding terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-11 is grounded at the signal terminal 113B of the temperature detection unit 113, 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, the other temperature detection units 113 in the same row group 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 working on the first detection channel A of the ADC unit 122 in this group. 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.

[0061] When the fourth control switch 124-4 is closed, the first control switch 124-1, the second control switch 124-2, and the third control switch 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. The temperature detection units 113 corresponding to electrode units 112-16 to 112-20 in the fourth row group are energized, while the temperature detection units 113 corresponding to electrode units 112-1 to 112-15 in the other row groups are de-energized. The signal terminals 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 in this group are short-circuited. 113B, since only the grounding terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-16 is connected to ground, while the grounding terminal 113A of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, and 112-11 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, the other temperature detection units 113 in the same row group will not affect the resistance value of the temperature detection unit 113 corresponding to electrode unit 112-16. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-16 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 unit 112-16. 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 112-17. 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 112-18. 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 112-19. 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 112-20.

[0062] Therefore, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can acquire the temperature detection signals of the temperature detection units 113 corresponding to all electrode units 112 of a certain electrode piece 110 by controlling a set of bidirectional switching switches 125 and a set of control switches 124 that are all 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 pieces 110 can be obtained.

[0063] 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, it closes the first control switch 124-1 in the corresponding group of control switches 124 and disconnects the remaining second control switches 124-2 to the fourth control switch 124-4 in the group of control switches 124. During this period, the group of ADC units 122... Each detection channel A, B, C, D, and E of the ADC unit 122 acquires the temperature detection signals of the temperature detection units 113 corresponding to each electrode unit 112 in the first row of the electrode sheet 110, converts them into digital signals, and stores them in a separately provided memory. Then, after a preset time interval, the first controller 121 or the second controller 131 closes the second control switch 124-2 in the group of control switches 124, and opens the first control switch 124-1, the third control switch 124-3, and the fourth control switch 124-4 in the 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 signals of the temperature detection units 113 corresponding to each electrode unit 112 in the second row of the electrode sheet 110. 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 sheet 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 sheets 110 can be obtained.

[0064] 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 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 period. For example, when only the first bidirectional switch 125-1 is switched to its terminal 1, the first control switch 124-1 can be closed first, and the second control switch 124-2, the third control switch 124-3, and the fourth control switch 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, the second control switch 124-2 is closed, and the first control switch 124-1, the third control switch 124-3, and the fourth control switch 124-4 are opened. When all control switches 124-4 are open, the ADC unit 122 in this group will detect the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-6. Then, the third control switch 124-3 is closed, and the first, second, and fourth control switches 124-1 and 124-2 are all open. At this time, the ADC unit 122 in this group will detect the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-11. Finally, the fourth control switch 124-4 is closed, and the first, second, and third control switches 124-1 and 124-2 are all open. At this time, the ADC unit 122 in this group will 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 column of electrode units 112 can be sampled. Similarly, the temperature detection signals of the temperature detection units 113 corresponding to other columns of electrode units 112 can be sampled in other acquisition time periods. That is, the switching unit (unlabeled) is configured to switch the dual-purpose signal line 119 corresponding to each column group to the corresponding temperature sampling point (unlabeled), and the switching state of the corresponding control switch 124 is configured so that the temperature detection signal detected by each temperature detection unit 113 in each column group is 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 within the same acquisition time period, which will not be described in detail here.

[0065] 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 all the control switches 124 of a set of control switches 124 electrically connected to the electrode plate 110 to be disconnected. At the same time, it controls each of the bidirectional switching switches 125 of a set of bidirectional switching switches 125 electrically connected to the electrode plate 110 to have two ends turned on and one end turned off, and controls a power supply switch 133 electrically connected to the electrode plate 110 to be turned 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 switch the dual-use signal lines 119 corresponding to at least two column groups to be simultaneously connected 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.

[0066] 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 all of the multiple control switches 124 of a set of control switches 124 electrically connected to the electrode plate 110 to be disconnected. At the same time, it controls only the first bidirectional switch 125-1 of the multiple bidirectional switches 125 of a set of bidirectional switches 125 electrically connected to the electrode plate 110 to be turned on at both ends and disconnected at the other end. It also controls a power supply switch 133 electrically connected to the electrode plate 110 to be turned 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. 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, so that the electrode unit 112 of each column group is simultaneously subjected to 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 simultaneously within the same time period, which will not be described in detail here.

[0067] Specifically, when it is necessary to determine the type of electrode 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can first sample the temperature detection signal detected by each temperature detection unit 113 in the aforementioned manner, and then determine the encoding array of the corresponding electrode 110 based on the sampled temperature detection signal detected by each temperature detection unit 113, and determine the type of the corresponding electrode 110 according to the encoding array. For example, the temperature sensor 114 in the temperature detection unit 113 is a negative temperature coefficient thermistor, whose characteristic is that the higher the temperature, the lower the resistance, and the lower the temperature, the higher the resistance. Since the electrode 110 is applied 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, you can choose a thermistor with model number NCP18XH103D03RB. When the temperature it senses is 0℃, the corresponding resistance is approximately 27.45KΩ; when the temperature it senses is 25℃, the corresponding resistance is approximately 10.0KΩ; and when the temperature it senses is 50℃, the corresponding resistance is approximately 4.16KΩ.

[0068] like Figure 5 As shown, when any control switch 124 is turned on, the DC power supply VCC provides DC power to the voltage divider resistor 123, the temperature sensor 114, and the 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, the diode 115, and the voltage divider resistor 123, and obtains the AD sampling value, that is, the voltage value (the voltage value of the thermistor), as shown in the following formula (1):

[0069] VADC=(VCC-VD)×R / (Rz+R) (1)

[0070] Where 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 diode 115, R is the resistance of the thermistor, and Rz is the resistance of the voltage divider resistor.

[0071] 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... The 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 temperature sensor 114 is 50℃, the corresponding resistance is approximately 4.16KΩ. Based on formula (1), the corresponding AD sampling value V50 = (3.3-0.3)×4.16 / (10+4.16) = 0.88V. When temperature sensor 114 is disconnected, for example, due to abnormal soldering or open circuit, the corresponding AD sampling value is 3.3V. When temperature sensor 114 and diode 115 are short-circuited, the corresponding AD sampling value is 0V.

[0072] Since the ADC unit 122 collects the voltage value of the temperature sensor 114, and the temperature sensor 114 has different voltage values ​​corresponding to different temperatures, 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 a corresponding code to identify the type of electrode sheet 110, that is, the number of electrode units 112 on the electrode sheet 110.

[0073] Specifically, taking the temperature sensor 114 sensing a temperature range of 0℃ to 50℃, and the AD sampling value obtained by the ADC unit 122 sampling, i.e. the voltage value, ranging from 0.88V to 2.20V, as an example, considering factors such as detection error, the voltage value range can be appropriately expanded to 0.5V to 3V.

[0074] When the AD sampling value obtained by ADC unit 122 is greater than 0.5V and less than 3V, the corresponding acquisition code is 1; when the AD sampling value obtained by ADC unit 122 is less than or equal to 0.3V, the corresponding acquisition code is 0; when the AD sampling value obtained by ADC unit 122 is greater than or equal to 3.1V, the corresponding acquisition code is 2. Therefore, in the corresponding detection positions numbered 1 to 20 of electrode plate 110, if temperature sensor 114 is short-circuited, the corresponding code is 0, i.e., the third code; if temperature sensor 114 is present, the corresponding code is 1, i.e., the first code; if temperature sensor 114 is absent or disconnected, the corresponding code is 2, i.e., the second code.

[0075] refer to Figure 5As shown, during sampling, regardless of the type of electrode 110 (i.e., the number of electrode units 112 or temperature sensors 114 of electrode 110 is less than or equal to 20), the ADC unit 122 acquires 20 AD sampling values ​​each time, and after each acquisition, it forms a 20-bit encoding array based on the 20 AD sampling values. Each type of electrode 110 has a corresponding encoding array, so the type of electrode 110 can be automatically identified through the encoding array.

[0076] The first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can determine the encoding array of the corresponding electrode piece 110 based on several AD sampling values, and determine the type of the corresponding electrode piece 110 based on the encoding array. For example... Figure 2 As shown, 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 of the electrode sheet 110 numbered 1 to 20 all have temperature sensors 114, and the codes are all 1. The 20 codes are combined to obtain a 20-bit code array 11111 11111 11111 11111.

[0077] like Figure 8 As shown, when the electrode sheet 310 has 13 electrode units 312 and 13 temperature detection units 313, the 13 electrode units 312 and 13 temperature detection units 313 are arranged in three rows and five columns in the circuit connection, and the 13 electrode units 312 and 13 temperature detection units 313 are arranged sequentially. A wire (unlabeled) is shorted at a corresponding position of the 13 temperature detection units 313. That is, a wire (unlabeled) is set at the intersection of the three rows and four columns in the circuit connection and shorted to the ground terminal 313A of the temperature detection unit 313 in the same row group, and at the same time shorted to the signal terminal 313B of the temperature detection unit 313 in the same column group. Each temperature detection unit 313 includes a temperature sensor 314 and a diode 315, with corresponding detection positions numbered 1 to 13. That is, each detection position of electrode plate 310 numbered 1 to 13 has a temperature sensor 314, and the code is 1. Unlike electrode plate 110 with 20 electrode units 112, the next detection position (i.e., the corresponding detection position number 14) does not have an electrode unit 312 (no temperature sensor 314) and is shorted in parallel by wires (unlabeled), with a corresponding code of 0. The corresponding detection positions numbered 15 to 20 do not have an electrode unit 312 (no temperature sensor 314) and are not shorted in parallel by wires (unlabeled), and are in an open state, with a corresponding code of 2. Therefore, the 20-bit code is combined to obtain a 20-bit code array of 11111 11111 11102 22222.

[0078] like Figure 13 As shown, when the electrode plate 710 has 9 electrode units 712 and 9 temperature detection units 713, the 9 electrode units 712 and 9 temperature detection units 713 are arranged in two rows and five columns in the circuit connection, and the 9 electrode units 712 and 9 temperature detection units 713 are arranged sequentially. A wire (unlabeled) is shorted at a corresponding position of the 9 temperature detection units 713. That is, a wire (unlabeled) is set at the intersection of the two rows and five columns in the circuit connection and shorted to the ground terminal 713A of the temperature detection unit 713 in the same row group, and at the same time shorted to the signal terminal 713B of the temperature detection unit 713 in the same column group. Each temperature detection unit 713 includes a temperature sensor 714 and a diode 715, with corresponding detection positions numbered 1 to 9. That is, each detection position numbered 1 to 9 of the electrode sheet 710 has a temperature sensor 714, and the code is 1. Unlike the electrode sheet 110 with 20 electrode units 112, the next detection position (i.e., the corresponding detection position number 10) does not have an electrode unit 712 (no temperature sensor 714) and is shorted by a wire (unlabeled), with a corresponding code of 0. The corresponding detection positions numbered 11 to 20 do not have an electrode unit 712 (no temperature sensor 714) and are not shorted by a wire (unlabeled), and are in an open state, with a corresponding code of 2. Therefore, the 20-bit code is combined to obtain a 20-bit code array 1111111110 22222 22222.

[0079] When the adapter 120 is not connected to the electrode plate 110, the ADC unit 122 collects the voltage of the DC power supply VCC, which is 3.3V. Therefore, the 20-bit encoding array is 22222 22222 22222 22222.

[0080] Based on the above patterns, we can deduce that: the corresponding code array for an electrode sheet with one electrode unit and one temperature detection unit is 10222 22222 22222 22222; the corresponding code array for an electrode sheet with two electrode units and two temperature detection units is 11022 22222 22222 22222; the corresponding code array for an electrode sheet with three electrode units and three temperature detection units is 11102 22222 22222 22222; the corresponding code array for an electrode sheet with four electrode units and four temperature detection units is 11110 2222222222 22222; the corresponding code array for an electrode sheet with five electrode units and five temperature detection units is 11111 02222 22222 22222; and the corresponding code array for an electrode sheet with six electrode units and six temperature detection units is 11111. The following are the encoding arrays for different electrode sheets: 10222 22222 22222; 10222 22222 22222; 10222 22222 22222; 10222 22222 22222; 10222 22222 22222; 10222 22222 22222; 10222 102222 22222; 10222 10222 22222; 10222 10222 22222; 10222 10222 10222 22222; 10222 10222 10222 22222 22222; 102 ... 22222; Electrode sheet with 12 electrode units and 12 temperature detection units, corresponding to the encoding array 11111 111111102222222; Electrode sheet with 13 electrode units and 13 temperature detection units, corresponding to the encoding array 1111111111 11102 22222; Electrode sheet with 14 electrode units and 14 temperature detection units, corresponding to the encoding array 11111 11111 11110 22222; Electrode sheet with 15 electrode units and 15 temperature detection units, corresponding to the encoding array 11111 11111 11111 02222; Electrode sheet with 16 electrode units and 16 temperature detection units, corresponding to the encoding array 11111 11111 1111110222; An electrode sheet with 17 electrode units and 17 temperature detection units has a corresponding encoding array of 11111 11111 11111 11022; An electrode sheet with 18 electrode units and 18 temperature detection units has a corresponding encoding array of 11111 11111 11111 11102;An electrode plate with 19 electrode units and 19 temperature detection units corresponds to the encoding array 11111 11111 11111 11110; an electrode plate with 20 electrode units and 20 temperature detection units corresponds to the encoding array 11111 11111 11111111111; when the adapter is not connected to any electrode plate, the corresponding encoding array is 22222 22222 22222 22222. The encoding array includes at least one of a first encoding, a second encoding, and a third encoding.

[0081] All 21 numbered arrays are different. Therefore, when the electrode plate 110 is normal, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can determine the type of electrode plate 110 connected to the adapter 120 or whether the electrode plate 110 is connected by the encoding array.

[0082] When the type of electrode 110 is determined, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 further determines whether the corresponding electrode 110 has a temperature detection fault according to the encoding array. The analog temperature signal detected by each sampled temperature detection unit 113 is also used to characterize whether the electrode 110 has a temperature detection fault.

[0083] like Figure 2 As shown, in an electrode sheet 110 with 20 electrode units 112 and 20 temperature detection units 113, if the temperature sensor 114 numbered 20 is damaged (open circuit), the AD sampling value obtained by the ADC unit 122 is 3.3V, the corresponding sampling code is 2, and the corresponding abnormal code array is 11111 11111 11111 11112. This code array is inconsistent with the normal code array 1111111111 11111 11111. Therefore, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can distinguish the temperature detection fault.

[0084] In summary, when the temperature sensor 114 of electrode 110 is functioning normally, the code "0" in the corresponding 20-bit encoding array is not the last bit, and all codes before the code "0" are "1", and all codes after the code "0" are "2"; or, the code "0" is the last bit and all codes before the code "0" are "1"; or, all codes in the 20-bit encoding array are "1". When the temperature sensor 114 of electrode 110 is damaged, regardless of whether the code "0" in the corresponding 20-bit encoding array is the last bit, the codes before the code "0" will be different from "1" (code "2"), or all codes in the 20-bit encoding array will be "1" or "2".

[0085] It should be noted that in this embodiment, the control switch 124, which is electrically connected to each of the multiple grounding lines 118 of the electrode plate 110, and the bidirectional switching switch 125, which is electrically connected to each of the multiple dual-purpose signal lines 119 of the electrode plate 110, are both located in the adapter 120. However, in other embodiments, the control switch 124, which is electrically connected to the grounding line 118, and the bidirectional switching switch 125, which is electrically connected to the dual-purpose signal line 119, may also be located on the electrode plate 110 or in the electric field generator 130, which will not be elaborated further 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.

[0086] Figure 6 The diagram shown is a schematic representation of a tumor electric field therapy system 200 according to a second embodiment of this application. Figures 1-4 Unlike the tumor electric field therapy system 100 shown, in terms of spatial structure, the multiple electrode units 212 of the electrode sheet 210 in this embodiment are connected in a symmetrical manner. For example, the electrode units 212 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-directed connecting strip (unlabeled). At the same time, the electrode units 212 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 connected by a column-directed connecting strip (unlabeled). As can be seen from the figure, the 10 electrode units 212 on the left and the 10 electrode units 212 on the right are symmetrically arranged.

Figure 1 Unlike the tumor electric field therapy system 100 shown, the electrode sheet 310 of this embodiment has 13 electrode units 312, which are arranged in a spatial structure according to a five-row, five-column arrangement. Figure 8 for Figure 7 The circuit connection diagram of the electrode 310 and the adapter 320 of the tumor electric field therapy system 300 is shown below. Figure 8As shown, the 13 electrode units 312 are configured in a three-row, five-column configuration in the circuit connection. The first two rows each contain 5 electrode units 312, and the third row contains 3 electrode units 312. Therefore, only three of the four control switches 324 are connected to the ground wire 318, while the other control switch 324 is left floating. A wire (unlabeled) is shorted at a corresponding position in the same row. That is, a wire (unlabeled) is set at the intersection of the three-row, four-column configuration in the circuit connection to short the ground terminal 313A of the temperature detection unit 313 in the same row, and at the same time to short the signal terminal 313B of the temperature detection unit 313 in the same column.

Figure 8 The circuit connection of the electrode plate 310 shown differs from that of the adapter 320. In this embodiment, the 13 electrode units 412 are configured in a four-row, four-column configuration. The first three rows each contain four electrode units 412, and the fourth row contains one electrode unit 412. Therefore, only four of the five bidirectional switches 425 are connected to the dual-purpose signal line 419, while the other bidirectional switch 425 is left floating. A wire (unlabeled) is shorted at a corresponding position in the same row. That is, a wire (unlabeled) is set at the intersection of the four rows and two columns in the circuit connection and shorted to the ground terminal 413A of the temperature detection unit 413 in the same row, and at the same time shorted to the signal terminal 413B of the temperature detection unit 413 in the same column.

Figure 11 The diagram shown is a schematic representation of a tumor electric field therapy system 600 according to a sixth embodiment of this application. Figure 7 The tumor electric field therapy system 300 shown differs in that the connecting strips (unlabeled) are arranged differently in terms of spatial structure, forming corresponding open spaces (unlabeled) or intervals (unlabeled) to suit different application methods, such as horizontal or vertical application, to prevent the electrode pads from lifting up during application.

[0093] Third examples:

[0094] Figure 12 The diagram shown is a schematic representation of a tumor electric field therapy system 700 according to the seventh embodiment of this application. Figure 1Unlike the tumor electric field therapy system 100 shown, the electrode sheet 710 of this embodiment has 9 electrode units 712, which are arranged in three rows and three columns in a spatial structure. Figure 13 for Figure 12 The circuit connection diagram of the electrode 710 and the adapter 720 of the tumor electric field therapy system 700 is shown below. Figure 13 As shown, the nine electrode units 712 are configured in two rows and five columns in the circuit connection. The first row contains five electrode units 712, and the second row contains four electrode units 712. Therefore, only two of the four control switches 724 are connected to the ground wire 718, while the other two control switches 724 are left floating. A wire (unlabeled) is shorted at a corresponding position in the same row. That is, a wire (unlabeled) is set at the intersection of the two rows and five columns in the circuit connection to short the ground terminal 713A of the temperature detection unit 713 in the same row and short the signal terminal 713B of the temperature detection unit 713 in the same column.

In this embodiment, the nine electrode units 812 are configured in three rows and three columns, with each row containing three electrode units 812. Therefore, only three of the four control switches 824 are connected to the ground wire 818, while the other control switch 824 is left floating. Only three of the five bidirectional switching switches 825 are connected to the dual-purpose signal line 819, while the other two bidirectional switching switches 825 are left floating.

[0096] It should be noted that for other related descriptions of the third embodiments, please refer to the related descriptions of the first embodiments, which will not be repeated here.

[0097] The electrode substrate of this application is electrically connected to the signal terminals of the same electrode unit and its corresponding temperature detection unit simultaneously via a single dual-purpose signal line. This allows for the transmission of both alternating current signals and DC signals for temperature signal acquisition, along with the acquired temperature detection signals, all through the dual-purpose signal line. Simultaneously, it significantly reduces the number of conductive traces (grounding wire, dual-purpose signal line) laid on the substrate, lowering the wiring complexity, simplifying the manufacturing process, reducing the substrate weight, and lowering manufacturing costs. Furthermore, it enables real-time and comprehensive temperature monitoring of all electrode units on the electrode sheet without increasing the weight of the electrode sheet or the number of cores in the first cable electrically connected to the electrode sheet. When the electrode sheet is qualified, the obtained temperature detection signals can be used to identify the electrode sheet type, thus automatically identifying the type of electrode sheet and enabling temperature acquisition for different types of electrode sheets without missing any data or generating interference signals. When the electrode sheet type is determined, the simulated temperature signal detected by each temperature detection unit is also used to characterize whether the electrode sheet has a temperature detection fault, thereby identifying abnormal temperature detection units.
