Tumor electric field treatment system, electrode sheet, tumor treatment device, and identification method

Abstract

This application provides a tumor electric field therapy system, electrode pads, tumor treatment equipment, and identification method. The system includes at least one pair of electrode pads, each electrode pad comprising multiple electrode units and multiple temperature detection units. Each temperature detection unit corresponds to one electrode unit, and the signal terminals of each temperature detection unit are short-circuited to their respective electrode units, and then connected to a switching unit via a dual-purpose signal line. Thus, multiple electrode units can be controlled and temperature detection signals sampled using fewer conductive traces. Furthermore, the type of electrode pad can be determined based on the sampled temperature detection signals, thereby enabling temperature acquisition of the corresponding type of electrode pad.

Description

Technical Field

[0001] This application relates to tumor electric field therapy technology, and more particularly to a tumor electric field therapy system, electrode pads, tumor treatment equipment, and identification method. Background Technology

[0002] Tumor electric field therapy is a treatment that uses low-intensity, medium-to-high-frequency alternating electric fields to prevent the formation of spindle microtubules during mitosis in certain tumor cells, inhibit 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. The adapter needs to collect analog temperature signals from these 9, 13, and 20 temperature sensors, thus requiring the determination of the appropriate electrode pad type. Summary of the Invention

[0006] This application aims to at least partially address one of the technical problems in the related art. Therefore, the first objective of this application is to propose a tumor electric field therapy system that uses fewer conductive traces to control multiple electrode units and sample temperature detection signals, and can automatically identify the type of electrode based on the sampled temperature detection signals, thereby achieving temperature acquisition for the corresponding type of electrode.

[0007] The second objective of this application is to provide an electrode sheet.

[0008] The third objective of this application is to propose another tumor electric field therapy system.

[0009] The fourth objective of this application is to provide a tumor treatment device.

[0010] The fifth objective of this application is to propose a method for identifying electrode type.

[0011] The sixth objective of this application is to provide a computer-readable storage medium.

[0012] The seventh objective of this application is to provide an adapter for tumor electric field therapy.

[0013] The eighth objective of this application is to provide an electric field generator for tumor electric field therapy.

[0014] To achieve the above objectives, a first aspect of this application provides a tumor electric field therapy system, comprising: at least one pair of electrode pads, each electrode pad including multiple electrode units and multiple temperature detection units, each electrode unit capable of applying an alternating electrical signal, each temperature detection unit corresponding to one electrode unit, and the signal terminals of each temperature detection unit being short-circuited to the corresponding electrode unit and 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, so that when the dual-purpose signal line is connected to the temperature sampling point, the analog temperature signal detected by the corresponding temperature detection unit is sampled based on the temperature sampling point, and the sampled analog temperature signal detected by the temperature detection unit is used to determine the encoding array of the corresponding electrode pad, the encoding array including a first code for indicating that the temperature detection unit is in a normal state, and the type of the corresponding electrode pad is determined by the first code in the encoding array; when the dual-purpose signal line is connected to the alternating power supply line, the corresponding electrode unit is applied the alternating electrical signal based on the alternating power supply line.

[0015] According to the tumor electric field therapy system of this application embodiment, for each electrode sheet, the signal terminal of the temperature detection unit corresponding to each electrode unit is short-circuited to the corresponding electrode unit and then connected to a switching unit through 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 analog temperature signal detected by the corresponding temperature detection unit to be sampled based on the temperature sampling point when the dual-purpose signal line is connected to the temperature sampling point, and the corresponding electrode unit to be applied an alternating electrical signal based on the alternating power supply line when the dual-purpose signal line is connected to the alternating power supply line. Thus, the system... The dual-purpose signal line enables temperature sampling and the application of alternating electrical signals without adding new AC signal lines (i.e., AC lines) and eliminating the need for existing AC signal lines. This allows for the control of multiple electrode units with fewer conductive traces, improving the effectiveness of tumor electric field therapy and facilitating electrode application. Simultaneously, the analog temperature signal detected by each sampled temperature detection unit is used to determine the corresponding electrode's encoding array. The encoding array determines the type of electrode, thus automatically identifying the electrode type and enabling temperature acquisition for the appropriate type of electrode.

[0016] To achieve the above objectives, a second aspect of this application provides an electrode pad applied to a tumor electric field therapy system. The tumor electric field therapy system includes a switching unit. The electrode pad includes: a substrate; multiple electrode units and multiple temperature detection units disposed on the substrate. Each electrode unit can apply an alternating electrical signal. Each temperature detection unit corresponds to one electrode unit, and the signal terminals of each temperature detection unit are short-circuited to the corresponding electrode unit and then connected to the switching unit via a dual-purpose signal line. The switching unit switches 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 analog temperature signal detected by the corresponding temperature detection unit is sampled based on the temperature sampling point. The sampled analog temperature signal detected by each temperature detection unit is used to determine the encoding array of the corresponding electrode pad. The encoding array includes a first code indicating that the temperature detection unit is in a normal state. The type of the corresponding electrode pad is determined by the first code in the encoding array. When the dual-purpose signal line is connected to the alternating power supply line, the corresponding electrode unit is applied the alternating electrical signal based on the alternating power supply line.

[0017] To achieve the above objectives, a third aspect of this application provides another tumor electric field therapy system, comprising: at least one pair of the aforementioned electrode pads; an electric field generator for generating an alternating electrical signal and transmitting the alternating electrical signal to each of the electrode pads via the alternating power line; and a control unit for configuring the switching state of the switching unit to sample the simulated temperature signal detected by the corresponding temperature detection unit based on the temperature sampling point, and determining the encoding array of the corresponding electrode pad according to the sampled simulated temperature signal detected by the temperature detection unit, the encoding array including a first code for indicating that the temperature detection unit is in a normal state, and determining the type of the corresponding electrode pad through the first code in the encoding array.

[0018] To achieve the above objectives, a fourth aspect of this application provides a tumor treatment device, including the aforementioned tumor electric field therapy system.

[0019] To achieve the above objectives, a fifth aspect of this application provides an electrode type identification method applied to the aforementioned tumor electric field therapy system. The method includes: determining a temperature detection signal for each electrode unit in each electrode sheet; determining a coding array for the corresponding electrode sheet based on the temperature detection signal, wherein the coding array includes a first code for indicating that the temperature detection unit is in a normal state; and determining the type of the corresponding electrode sheet based on the first code in the coding array.

[0020] To achieve the above objectives, a sixth aspect of this application provides a computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the aforementioned electrode type identification method.

[0021] To achieve the above objectives, a seventh aspect of this application provides an adapter for tumor electric field therapy, including a first memory and a first controller, characterized in that the first memory stores a computer program, which, when executed by the first controller, implements the aforementioned electrode type identification method.

[0022] To achieve the above objectives, an eighth aspect of this application provides an electric field generator for tumor electric field therapy, including a second memory and a second controller, characterized in that the second memory stores a computer program, which, when executed by the second controller, implements the aforementioned electrode type identification method.

Detailed Implementation

[0049] 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.

[0050] Some embodiments:

[0051] 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 1 As shown, the tumor electric field therapy system 100 includes: at least one pair of electrode pads 110, an adapter 120 connected to the at least one pair of electrode pads 110, and an electric field generator 130 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 1The 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.

[0052] 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.

[0053] 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 therein, 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.

[0054] 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 structure shown is generally array-like, but it can also be other structures, such as petal-shaped or scattering-shaped, and can be regular or irregular. Electrode unit 112 is configured to apply alternating electrical signals to the patient's tumor site. Temperature detection unit 113 is configured to detect the temperature of the patient's body surface that is in contact with electrode pad 110, i.e., the temperature at the corresponding electrode unit 112, and output the temperature detection signal to an external device such as adapter 120. In this embodiment, the multi-purpose signal lines 119 of substrate 111 are respectively arranged in a one-to-one correspondence with multiple columns of electrode units 112, and are configured to transmit the alternating electrical signals generated by 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 multi-purpose signal line 119 of substrate 111, and electrode units 112 located in different columns are connected in parallel through different multi-purpose signal lines 119 of 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.

[0055] 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.

[0056] 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.

[0057] 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, preventing the cable from becoming thicker and harder, thus increasing the difficulty of cable fixation; simultaneously, it avoids the increased number of wires in the first cable 116 affecting the adhesion between the electrode pad 110 and the corresponding body surface of the patient's tumor site. The substrate 111 has a total of 9 embedded grounding wires 118 and dual-purpose signal lines 119. Specifically, in this embodiment, the substrate 111 has 4 embedded grounding wires 118 and 5 embedded dual-purpose signal lines 119. The number of grounding wires 118 is related to the number of rows M of the electrode unit 112, and is greater than or equal to the number of rows M, where M is a positive integer. The number of dual-purpose signal lines 119 is related to the number of columns N of the electrode unit 112, and is greater than or equal to the number of columns N, where N is a positive integer. The number of lines L embedded in the substrate 111 of the electrode sheet 110 is equal to the sum of the number of ground lines 118 and the number of dual-purpose signal lines 119. In this embodiment, the number of ground lines 118 is equal to the number of rows M of the electrode unit 112; the number of dual-purpose signal lines 119 is equal to the number of columns N of the electrode unit 112.

[0058] 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 1As 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. Each of the first and fourth rows has four electrode units 112, and each of the second and third rows has six electrode units 112. The four electrode units 112 in each of the first and fourth rows are located in 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.

[0059] like Figure 1As shown, in terms of spatial structure, multiple electrode units 112 are connected in an asymmetrical manner. For example, in the four electrode units 112 located in the first row and third column, the second row and third column, the third row and third column, and the fourth row and third column, adjacent electrode units 112 are connected by a column-directed connecting strip (unlabeled). At the same time, in the four electrode units 112 located in the first row and fifth column, the second row and fifth column, the third row and fifth column, and the fourth row and fifth column, adjacent electrode units 112 are also connected by a column-directed connecting strip (unlabeled). Each electrode sheet 110 has a free end. For example, among the multiple electrode units 112, at least one electrode unit 112 is connected to at most one other electrode unit 112. For instance, each electrode unit 112 located in the first row, second column, second row, first column, second row, second column, third row, first column, third row, and fourth row, second column has no connecting strips in its column direction, thus forming an open space. This open space is adjustable; for example, the position of the electrode unit 112 in the first row, second column is movable relative to the position of the electrode unit 112 in the first row, third column, and so on. The position of the electrode unit 112 in the first row and second column is movable relative to the position of the electrode unit 112 in the third row and second column, and the position of the electrode unit 112 in the fourth row and second column is movable relative to the position of the electrode unit 112 in the fourth row and third column. Thus, when the electrode pad 110 is applied to the patient's body surface, the open space between the corresponding electrode units 112 can be adjusted by adjusting the positions of the electrode units 112 in the first row and second column, the second row and first column, the third row and first column, and the fourth row and second column. This increases the heat dissipation space of the corresponding electrode units 112, thereby accelerating heat dissipation. At the same time, it is beneficial for the patient to adjust the position of the electrode units 112 based on the fever or the skin condition of the area where the electrode pad 110 is applied.Similarly, the electrode units 112 located in the first row, fourth column, second row, fourth column, second row, sixth column, third row, and fourth row, fourth column, are also not connected by connecting strips in their column direction, thus forming an open space. This open space is adjustable; for example, the position of the electrode unit 112 in the first row, third column, relative to the position of the electrode unit 112 in the first row, fifth column, the second row, fourth column, and second row, sixth column, relative to the position of the electrode unit 112 in the second row, fifth column, and so on, can be adjusted. The electrode unit 112 in the fourth row and fourth column is movable relative to the electrode unit 112 in the fourth row and fifth column. Therefore, when the electrode pad 110 is applied to the patient's body surface, the open space between the corresponding electrode units 112 can be adjusted by adjusting the positions of the electrode units 112 in the first row and fourth column, the second row and fourth column, the second row and sixth column, the third row and sixth column, and the fourth row and fourth column. This can increase the heat dissipation space of the corresponding electrode units 112, thereby accelerating heat dissipation. At the same time, it is beneficial for the patient to adjust the position of the electrode units 112 based on the fever or the skin condition of the area where the electrode pad 110 is applied.

[0060] like Figure 1 As shown, in terms of spatial structure, the four electrode units 112 located in the first row can be divided into region 1; the four electrode units 112 located in the first column of the second row, the first column of the third row, the second column of the fourth row, and the third column of the fourth row can be divided into region 2; the four electrode units 112 located in the sixth column of the second row, the sixth column of the third row, the fourth column of the fourth row, and the fifth column of the fourth row can be divided into region 3; the four electrode units 112 located in the second column of the second row, the third column of the second row, the second column of the third row, and the third column of the third row can be divided into region 4; and the four electrode units 112 located in the fourth column of the second row, the fifth column of the second row, the fourth column of the third row, and the fifth column of the third row can be divided into region 5. The electrode units 112 in each region (1-5) are... Figure 2 The circuit connections shown correspond to a column group, and the corresponding 20 electrode units 112 are arranged in a four-row, five-column group. In other embodiments, the 20 electrode units 112 can also be arranged in other ways. Of course, in 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.

[0061] Each electrode unit 112 can be subjected to an alternating electrical signal, thereby enabling the paired electrode pads 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 a polymer dielectric layer made of polymer material. Each temperature detection unit 113 is provided corresponding to one electrode unit 112 to detect the temperature at the corresponding electrode unit 112. Each temperature detection unit 113 can be 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. For example, each electrode unit 112 has a through hole 1121 in the middle, and each electrode unit 112 has a corresponding temperature detection unit 113 housed in the through hole 1121. Each temperature detection unit 113 includes a temperature sensor 114 and a diode 115. The temperature sensor 114 has a signal terminal 114B and a ground terminal 114A. The diode 115 has an anode 115B and a cathode 115A. The anode 115B of the diode 115 is connected to the ground terminal 114A of the temperature sensor 114, and the cathode 115A of the diode 115 serves as the 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 correspondingly provided with a diode 115. The diode 115 is connected in series with the temperature sensor 114 of the corresponding electrode unit 112. It can prevent the reverse flow of current to prevent the detection signal from other electrode units 112 from affecting the temperature sensor 114.

[0062] 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 electrode units 112-1 to 112-5 in the first row group; the second grounding wire 118-2 is used to ground electrode units 112-6 to 112-10 in the second row group; the third grounding wire 118-3 is used to ground electrode units 112-11 to 112-15 in the third row group; and the fourth grounding wire 118-4 is used to ground electrode units 112-16 to 112-20 in the fourth row group. It should be noted that these grounding wires 118 can be selectively closed or opened. This can be achieved by connecting each grounding wire 118 in series with a control switch 124. That is, the grounding 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 aforementioned "grounding 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 connecting the diode 115 in series with the temperature sensor 114 corresponding to the same electrode unit 112 and grounding them together. In short, each grounding wire 118 short-circuits and grounds the grounding terminal 113A of the temperature detection unit 113 corresponding to all electrode units 112 in each row group.

[0063] 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 all electrode units 112 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 one of the electrode units 112 or not connected to any of the electrode units 112 in that row group to avoid subsequent repetitive signal output from the dual-purpose signal line 119. 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 signal terminals 113B; one end of the fourth dual-purpose signal line 119-4 is simultaneously 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 parallel within the same column group as temperature sampling points (unlabeled) for connection to external devices. It should be noted that these dual-purpose signal lines 119 can selectively transmit alternating electrical signals or receive temperature detection signals. This can be achieved by connecting each dual-purpose signal line 119 in series with a bidirectional switching switch 125 and 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. The switching unit (unlabeled) includes multiple bidirectional switching switches 125, which are configured to switch the dual-purpose signal line 119 to the temperature sampling point (unlabeled) or the alternating power line 127. When the dual-purpose signal line 119 is connected to the temperature sampling point (unlabeled), the switching state of the control switch 124 is configured so that the temperature detection signal detected by the corresponding temperature detection unit 113 in each row group is sampled based on the temperature sampling point (unlabeled). 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-purpose signal line 119 is connected to the alternating power line 127, at least one column group's electrode unit 112 is applied with an alternating electrical signal based on the alternating power line 127, which will be described in detail below.

[0064] 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.

[0065] 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.

[0066] 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 and columns of the electrode units 112 of the electrode piece 110; the number H of circuit lines electrically connecting the adapter 120 to X electrode pieces 110 is equal to X times the number of circuit lines electrically connecting it to a single electrode piece 110, that is, H = XL = X*(M+N). The number of groups of control switches 124 and the number of groups of bidirectional switching switches 125 are related to the number of electrode pieces 110. The number of groups of control switches 124 is the same as the number of groups of bidirectional switching switches 125, and is not less than the number of electrode pieces 110. Optionally, the number of groups of control switches 124 and bidirectional switching switches 125 is the same as the number of electrode pieces 110. The following is a detailed description of the electrical connection between an electrode piece 110 with 20 electrode units 112 and the adapter 120.

[0067] 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, that is, related to the number of rows of multiple electrode units 112 configured; in this embodiment, both are equal. Figure 2 As shown, in this embodiment, the multiple control switches 124 in each group of control switches 124 are respectively the first control switch 124-1, the second control switch 124-2, the third control switch 124-3, and the fourth control switch 124-4. The multiple control switches 124 in the same group each control the closing or opening of the corresponding grounding wire 118 of the same electrode plate 110. Specifically, the first control switch 124-1 is used to control the opening or closing of the first grounding wire 118-1 of the corresponding electrode plate 110, and can cooperate with the corresponding set of bidirectional switching switches 125 to control the power supply 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 power supply 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 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 (112-11 to 112-15) in the third row of the electrode plate 110; 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 (112-16 to 112-20) in the fourth row of the electrode plate 110. 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.

[0068] 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.

[0069] 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) that correspond one-to-one with the multi-purpose signal lines 119 of the corresponding electrode plate 110. The number of bidirectional switching switches 125 in each group of bidirectional switching switches 125 is related to the number of multi-purpose signal lines 119 on the substrate 111 of the corresponding electrode plate 110, which 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, the two are equal. Each bidirectional switch 125 has two ends labeled 1 and 2. The ends of multiple bidirectional switches 125 in the same group are electrically connected to the corresponding detection channels of the multiple detection channels of the corresponding group of ADC units 122 through temperature sampling points (unlabeled). The ends of each bidirectional switch 125 in the same group are electrically connected to the same AC power line 127 and are configured to control the multiplex signal line 119 to connect to the corresponding AC power line 127 to transmit AC electrical signals or to connect to the corresponding detection channel of the corresponding group of ADC units 122 to receive the temperature detection signal output by the temperature detection unit 113.

[0070] 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 in each group of 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 control the switching of a corresponding dual-purpose signal line 119 of the multi-channel 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 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 corresponding to 2-16 and the corresponding control switches 124-1, 124-2, 124-3, and 124-4, 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 output the temperature data collected by the temperature detection units 113 corresponding to these electrode units 112 to the corresponding ADC unit 122. Signal; The second bidirectional switch 125-2 is used to control the switching of the second dual-purpose signal line 119-2 of the corresponding electrode 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 110, including electrode units 112-2, 112-7, 112-12, and 112-17, and the conduction of each electrode unit 112 in the second column group of the electrode 110. -17 The signal terminal 113B of each temperature detection unit 113 corresponding to the temperature detection unit 113 is turned on to switch between the two and cooperate with the corresponding control switches 124-1, 124-2, 124-3, and 124-4 so that the second column of electrode units 112-2, 112-7, 112-12, and 112-17 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 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, including electrode units 112-3, 112-8, 112-13, and 112-18, and the conduction of each electrode unit 112 in the third column group of the electrode plate 110.

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 the preset temperature threshold (e.g., 41°C, 42°C, etc.). At this time, the voltage of the alternating electrical signal output by the electric field generator 130 can be appropriately reduced to avoid the electrode 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.

[0077] 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.

[0078] 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.

[0079] Specifically, when control switch 124-1 is closed, and control switches 124-2, 124-3, and 124-4 are all open, and the first bidirectional switching switch 125-1, the second bidirectional switching switch 125-2, the third bidirectional switching switch 125-3, the fourth bidirectional switching switch 125-4, and the fifth bidirectional switching switch 125-5 are all switched to their respective terminals 1, the temperature detection units 113 corresponding to electrode units 112-1 to 112-5 in the first row group are energized, while the temperature detection units 113 corresponding to electrode units 112-6 to 112-20 in the remaining rows are de-energized. In this group of ADC units 122, the temperature detection units corresponding to electrode units 112-1, 112-6, 112-11, and 112-16 in the first detection channel A are short-circuited. Since only the signal terminal 113B of the temperature detection unit 113 corresponding to electrode unit 112-1 is grounded, 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, it 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.

Electrode units 112-1, 112-6, 112-11, and 112-16 are short-circuited on the first detection channel A of the ADC unit 122 in this group. 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 resistance value of the temperature detection unit 113 corresponding to electrode unit 112-6 will not be affected. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-6 is effectively operating on the first detection channel A of this group of ADC units 122. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-6. Similarly, the voltage value collected on the second detection channel B of this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-7. 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 112-8. 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 112-9.

In this group of ADC units 122, electrode units 112-1, 112-6, 112-11, and 112-16 are short-circuited on the first detection channel A. Since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-11 is grounded, while the ground 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 resistance value of the temperature detection unit 113 corresponding to electrode unit 112-11 will not be affected. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-11 is effectively operating on the first detection channel A of this ADC unit 122. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-11. Similarly, the voltage value collected on the second detection channel B of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-12. The voltage value acquired on the third detection channel C of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-13.

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 units 112-15.

[0082] When control switch 124-4 is closed, control switches 124-1, 124-2, and 124-3 are all open, and the first bidirectional switching switch 125-1, the second bidirectional switching switch 125-2, the third bidirectional switching switch 125-3, the fourth bidirectional switching switch 125-4, and the fifth bidirectional switching switch 125-5 are all switched to their respective terminals 1. 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 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. For signal terminal 113B of ADC unit 3, only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-16 is grounded, while the ground terminals 113A of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, and 112-11 are disconnected. Furthermore, each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, which does 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 ADC unit 122. At this time, the temperature detection signal (voltage value) acquired by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-16. Similarly, the voltage value acquired on the second detection channel B of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-17. The voltage value acquired on the third detection channel C of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-18. The voltage value acquired on the fourth detection channel D of this ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-19. The voltage value 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 units 112-20.

[0083] 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.

[0084] The first controller 121 or the second controller 131, multiple ADC units 122, and multiple bidirectional switching switches 125 can automatically perform 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 control switch 124-1 in the corresponding group of control switches 124 and opens the remaining control switches 124-2 to 124-4 in the group of control switches 124. During this period, the group of ADC units 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 control switch 124-2 in the group of control switches 124, and opens control switches 124-1, 124-3, and 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, this operation can be used to obtain the temperature detection signals of all temperature detection units 113 on at least one pair of electrode sheets 110.

[0085] 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, switch 124-1 can be closed first, and switches 124-2, 124-3, and 124-4 can be opened. At this time, only the temperature detection unit 113 corresponding to the electrode unit 112-1 of the first row group is energized. The signal terminal 113B of the temperature detection unit 113 corresponding to the electrode unit 112-1 is shorted on the first detection channel A of the ADC unit 122 of this group. Therefore, the ADC unit 122 of this group will detect the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-1. Then, control switch 124-2 is closed, and switches 124-1, 124-3, and 124-4 are opened. When control switches 124-4 are all 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, control switch 124-3 is closed, and control switches 124-1, 124-2, and 124-4 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, control switch 124-4 is closed, and control switches 124-1, 124-2, and 124-3 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 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.

[0086] Specifically, when it is necessary to apply an alternating electrical signal to each electrode unit 112 of an electrode plate 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls each of the multiple bidirectional switching switches 125 electrically connected to the electrode plate 110 to turn on two ends and turn off one end. At the same time, it controls all the multiple control switches 124 electrically connected to the electrode plate 110 to turn off, and controls a power supply switch 133 electrically connected to the electrode plate 110 to turn on. At this time, the second controller 131 of the electric field generator 130 controls the AC signal generator 132 to apply an alternating electrical signal to each electrode unit 112 of the electrode plate 110 through the alternating power line 127, and the magnitude of the applied alternating electrical signal voltage or current is adjustable. That is, the switching unit (unlabeled) is configured to 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.

[0087] It should be noted that in other embodiments, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can also control a set of bidirectional switching switches 125 electrically connected to a certain electrode plate 110 to apply alternating electrical signals to a portion of the electrode units 112 of the electrode plate 110 at the same time period. For example, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls the first bidirectional switch 125-1 of a group of bidirectional switches 125 electrically connected to the electrode plate 110 to turn on at both ends and turn off at the other end. At the same time, it controls all the control switches 124 of a group of control switches 124 electrically connected to the electrode plate 110 to turn off, and controls a power supply switch 133 electrically connected to the electrode plate 110 to turn on. At this time, the second controller 131 of the electric field generator 130 controls the AC signal generator 132 to apply an alternating electrical signal to the first column of electrode units 112-1, 112-6, 112-11 and 112-16 of the electrode plate 110 through the alternating power line 127, and the magnitude of the applied alternating electrical signal voltage or current is adjustable. That is, the switching unit (unlabeled) is configured to switch the dual-purpose signal line 119 corresponding to each column group to the alternating power supply line 127, 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.

[0088] 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.

[0089] 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):

[0090] VADC=(VCC-VD)×R / (Rz+R) (1)

[0091] 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.

[0092] 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.

[0093] 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.

[0094] 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.

[0095] 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 position 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.

[0096] During sampling, different types of electrode sheets 110 correspond to different numbers of first codes, thus obtaining different code arrays. Therefore, the type of electrode sheet 110 can be automatically identified by the first code in the code array.

[0097] 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.

[0098] like Figure 10 As shown, when the electrode plate 410 has 13 electrode units 412 and 13 temperature detection units 413, the 13 electrode units 412 and 13 temperature detection units 413 are arranged in a three-row, five-column configuration in the circuit connection, and the 13 electrode units 412 and 13 temperature detection units 413 are arranged sequentially. Each temperature detection unit 413 includes a temperature sensor 414 and a diode 415, with corresponding detection bit numbers from 1 to 13. That is, the corresponding detection bits numbered 1 to 13 of the electrode plate 410 all have temperature sensors 414, and the code is 1 for each. Therefore, combining the 13-bit codes yields a 13-bit code array of 1111111111 111. Similarly, Figure 12 The electrode sheet 510 shown Figure 13 The electrode sheet 610 shown Figure 15 The coding array corresponding to the electrode sheet 710 shown is 11111 11111 111.

[0099] like Figure 19 As shown, when the electrode plate 1010 has 9 electrode units 1012 and 9 temperature detection units 1013, the 9 electrode units 1012 and 9 temperature detection units 1013 are arranged in two rows and five columns in the circuit connection, and the 9 electrode units 1012 and 9 temperature detection units 1013 are arranged sequentially. Each temperature detection unit 1013 includes a temperature sensor 1014 and a diode 1015, with corresponding detection bit numbers from 1 to 9. That is, the corresponding detection bits numbered 1 to 9 of the electrode plate 1010 all have temperature sensors 1014, and the code is 1 for each. Therefore, the 9-bit code is combined to obtain a 9-bit code array 111111111. Similarly, Figure 21The coding array corresponding to electrode 1110 shown is 11111 1111.

[0100] Based on the above patterns, we can conclude that: an electrode sheet with 1 electrode unit and 1 temperature detection unit corresponds to the code array 1; an electrode sheet with 2 electrode units and 2 temperature detection units corresponds to the code array 11; an electrode sheet with 3 electrode units and 3 temperature detection units corresponds to the code array 111; an electrode sheet with 4 electrode units and 4 temperature detection units corresponds to the code array 1111; an electrode sheet with 5 electrode units and 5 temperature detection units corresponds to the code array 11111; an electrode sheet with 6 electrode units and 6 temperature detection units corresponds to the code array 11111 1; an electrode sheet with 7 electrode units and 7 temperature detection units corresponds to the code array 1111111; an electrode sheet with 8 electrode units and 8 temperature detection units corresponds to the code array 11111 111; and an electrode sheet with 9 electrode units and 9 temperature detection units corresponds to the code array 11111. 1111; An electrode sheet with 10 electrode units and 10 temperature detection units has a corresponding code array of 1111111111; An electrode sheet with 11 electrode units and 11 temperature detection units has a corresponding code array of 11111 11111 1; An electrode sheet with 12 electrode units and 12 temperature detection units has a corresponding code array of 11111 11111 11; An electrode sheet with 13 electrode units and 13 temperature detection units has a corresponding code array of 11111 11111 111; An electrode sheet with 14 electrode units and 14 temperature detection units has a corresponding code array of 11111 11111 1111; An electrode sheet with 15 electrode units and 15 temperature detection units has a corresponding code array of 11111 11111. 11111; An electrode sheet with 16 electrode units and 16 temperature detection units has a corresponding encoding array of 11111 11111 11111 1; An electrode sheet with 17 electrode units and 17 temperature detection units has a corresponding encoding array of 11111 1111111111 11; An electrode sheet with 18 electrode units and 18 temperature detection units has a corresponding encoding array of 11111 11111 11111 111; An electrode sheet with 19 electrode units and 19 temperature detection units has a corresponding encoding array of 11111 11111 11111 1111; An electrode sheet with 20 electrode units and 20 temperature detection units has a corresponding encoding array of 11111 11111 11111 11111. The encoding array includes the first code.

[0101] Since all 20 numbered arrays are different, 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 110 connected to the adapter 120 by means of the coded array when the electrode 110 is normal.

[0102] 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.

[0103] like Figure 2 As shown, in an electrode sheet 110 with 20 electrode units 112 and 20 temperature detection units 113, if the temperature 114 numbered 20 in the corresponding electrode sheet 110 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 11111 11111111111 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.

[0104] In summary, when the temperature sensor 114 of electrode 110 is functioning normally, the corresponding codes in the code array are all "1", that is, the first code.

[0105] 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.

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

Figure 1 The tumor electric field therapy system 100 of the first embodiment shown differs in that, in terms of spatial structure, the multiple electrode units 312 of the electrode sheet 310 in this embodiment are connected in a symmetrical manner. For example, the four electrode units 312 located in the first row and third column, the second row and third column, the third row and third column, and the fourth row and third column are also connected by a column-directed connecting strip (unlabeled). At the same time, the four electrode units 312 located in the first row and fourth column, the second row and fourth column, the third row and fourth column, and the fourth row and fourth column are connected by a column-directed connecting strip (unlabeled). As can be seen from the figure, the 10 electrode units 312 on the left and the 10 electrode units 312 on the right are symmetrically arranged.

Adjacent electrode units 412 in each of the five rows are connected by a connecting strip (unlabeled). Adjacent electrode units 412 in each of the first, third, and fifth columns are also connected by a connecting strip (unlabeled).

The first two rows each contain 5 electrode units 412, and the third row contains 3 electrode units 412. Therefore, there are only three control switches 424 and three grounding wires 418.
