The electrode sheet comprises a plurality of electrode units and a plurality of temperature detection units. The plurality of electrode units are divided into a plurality of row groups and a plurality of column groups.

Description

Technical Field

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

[0002] Currently, tumor electric field therapy 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 the alternating electric signal for tumor electric field therapy to each electrode pad through the adapter, and then applies the alternating electric field to the patient's tumor site for tumor electric field therapy. Because the alternating electric field applied to the patient will accumulate heat at the corresponding location where the electrode pad is attached to the skin, a temperature sensor needs to be installed at each electrode unit to monitor the skin surface temperature at each electrode unit in order to avoid low-temperature burns. However, during the use of electrode pads for tumor treatment, there is an inevitable problem that a very small number of electrode pads may experience individual temperature sensor malfunctions after a period of use. If too many temperature sensors on an electrode pad fail, it can easily lead to the risk of low-temperature burns for the patient. Summary of the Invention

[0003] This application aims to at least partially address one of the technical problems in the related art. To this end, the first objective of this application is to provide a tumor electric field therapy system that can achieve zoned control of multiple electrode units and sampling of temperature detection signals using fewer conductive traces. This not only improves the efficacy of tumor electric field therapy but also facilitates electrode application. Furthermore, during electrode use, the sampled temperature detection signals can monitor whether the electrode is damaged, allowing for timely replacement and avoiding or reducing the risk of low-temperature burns to patients. During electrode production, the sampled temperature detection signals can monitor whether each temperature detection unit of the electrode is properly connected, thereby determining the electrode's qualification and screening out unqualified electrodes, ensuring that each temperature detection unit of the manufactured electrode can perform normal detection. In addition, the adapter in this embodiment can adapt to electrode sheets with different numbers of electrode units.

[0004] To achieve the above objectives, a first aspect of this application provides a tumor electric field therapy system, comprising: an electrode sheet having multiple electrode units and multiple temperature detection units, each electrode unit being capable of applying an alternating electrical signal, each temperature detection unit being respectively configured corresponding to one of the electrode units for detecting the temperature at each electrode unit, and the signal terminals of each temperature detection unit being short-circuited to the corresponding electrode unit, wherein the multiple temperature detection units are configured in a circuit as multiple row groups and multiple column groups, the ground terminals of each temperature detection unit located in the same row group are short-circuited to the same grounding line, and the ground terminals of each temperature detection unit located in different row groups are respectively connected in parallel through different grounding lines; the signal terminals of each temperature detection unit located in the same column group are short-circuited to the same dual-purpose signal line, and the signal terminals of each temperature detection unit located in different column groups are respectively connected through different dual-purpose signal lines. Parallel connection; the dual-purpose signal line is configured to switch between conducting an AC signal transmission path to transmit AC signals to each of the electrode units and conducting a DC signal transmission path to transmit DC signals to the signal terminals of each of the temperature detection units; and a controller configured to combine control of the conduction states of each of the grounding lines and each of the dual-purpose signal lines so that (1) when the dual-purpose signal line conducts a DC signal transmission path to transmit DC signals to the signal terminals of each of the temperature detection units, each of the grounding lines is sequentially and individually conducted so that the temperature detection signals detected by each of the temperature detection units are sampled line by line, the sampled temperature detection signals detected by each of the temperature detection units are used to determine the test code array of the electrode sheet, the test code array is used to perform a consistency comparison with a standard code array; (2) when the dual-purpose signal line conducts an AC signal transmission path, AC signals are transmitted to each of the electrode units.

[0005] The second objective of this application is to propose a method for detecting the quality of electrode sheets.

[0006] To achieve the above objectives, a second aspect of this application provides an electrode temperature detection method applied to the aforementioned tumor electric field therapy system. The method includes: switching each of the dual-purpose signal lines to conduct their DC signal transmission paths to provide DC signals to the signal terminals of each of the temperature detection units; and sequentially activating each of the grounding lines to acquire the temperature detection signals detected by each temperature detection unit row by row.

Detailed Implementation

[0025] 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.

[0026] Some embodiments:

[0027] 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 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 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.

[0028] 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.

[0029] Figure 2 for Figure 1 The diagram shows the circuit connection between an electrode 110 and an adapter 120 in 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.

[0030] 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 is shorted to the corresponding temperature detection unit 113. 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] like Figure 1As shown, in terms of spatial structure, multiple electrode units 112 are connected in an asymmetrical manner. For example, adjacent electrode units 112 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 are connected by a column-directed connecting strip (unlabeled). At the same time, adjacent electrode units 112 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 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, also have no connecting strips in the column direction, thus forming an open space. This open space is adjustable; for example, the position of the electrode unit 112 in the first row, fourth column, 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 position of the electrode unit 112 in the fourth row and fourth column is movable relative to that in the fourth row and fifth 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 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 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.

[0036] 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, 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 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.

[0037] 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.

[0038] 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.

[0039] 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. This switching unit (unlabeled) includes multiple bidirectional switching switches 125, which are 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 switching state of the control switch 124 can be configured to control the temperature detection signal detected by the corresponding temperature detection unit 113 in each row group. Based on the sampling of temperature sampling points (unlabeled) and with the dual-purpose signal line 119 connected to the alternating power line 127, at least one column of electrode units 112 is subjected to an alternating electrical signal based on the alternating power line 127. The analog temperature signal detected by each sampled temperature detection unit 113 is used to determine the test code array of the corresponding electrode piece 110. By comparing the test code array with the standard code array, the fault condition of each temperature detection unit 113 in the corresponding electrode piece 110 is identified, or the corresponding electrode piece 110 is judged to be qualified. This will be described in detail below.

[0040] 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.

[0041] 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.

[0042] 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 greater than or 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 greater than or 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). In this embodiment, 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 both 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 control switches 124 and bidirectional switching switches 125 is the same as the number of electrode plates 110. The following is a detailed description of the electrical connection between an electrode plate 110 with 20 electrode units 112 and the adapter 120.

[0043] 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 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 from electrode unit 112-1 to electrode unit 112-5 in the first row of the electrode plate 110; the second control switch 124-2 is used to control the opening or closing of the second grounding wire 118-2 of the electrode plate 110, and can cooperate with the corresponding set of bidirectional switching switches 125 to control the power supply and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 from electrode unit 112-6 to electrode unit 112-10 in the second row of the electrode plate 110. 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.

[0044] 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.

[0045] 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.

[0046] 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 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 sheet 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 sheet 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 sheet 110. The switching between the conduction of the signal terminals 113B of each temperature detection unit 113 corresponding to 17 and 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 can 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. The switching between the conduction of the signal terminals 113B of each temperature detection unit 113 corresponding to 8 and the corresponding control switches 124-1, 124-2, 124-3, and 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 fourth bidirectional switching 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 the electrode plate 110, including electrode units 112-4, 112-9, 112-14, and 112-19, and the conduction of each electrode unit 112 in the fourth column group of the electrode plate 110. The switching between the conduction of the signal terminals 113B of each temperature detection unit 113 corresponding to 19 and the corresponding control switches 124-1, 124-2, 124-3, and 124-4, so that the fourth column of electrode units 112-4, 112-9, 112-14, and 112-19 can 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 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, including electrode units 112-5, 112-10, 112-15, and 112-20, and the conduction of each electrode unit 112 in the fifth column group. The switching between the conduction of the signal terminals 113B of each temperature detection unit 113 corresponding to 0 and the switching between the two functions, in conjunction with the corresponding control switches 124-1, 124-2, 124-3, and 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 both ends of each group of bidirectional switching switches 125 are on and one end is off, alternating electrical signals can be transmitted to each electrode unit 112 of the corresponding electrode pad 110. When one end of each group of bidirectional switching switches 125 is on and two ends are off, it can cooperate with each control switch 124 in the corresponding group of control switches 124 to sequentially and time-divisionally transmit the temperature detection signals collected by the temperature detection units 113 of each electrode unit 112 on the electrode pad 110. The aforementioned bidirectional changeover switch 125 can be a mechanical switch, such as a relay. The bidirectional changeover switch 125 can also be an electronic switch, and each bidirectional changeover switch 125 can be switched via an additional first controller 121.

[0047] 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.

[0048] 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-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, which are set one-to-one with the corresponding temperature detection points (unlabeled). Each detection channel A, B, C, D, and E is used to connect to one of the corresponding bidirectional switching switches 125 of the multi-purpose signal line 119. 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. Each detection channel A, B, C, D, and E is used to receive the temperature detection signal collected by the temperature detection unit 113 corresponding to the electrode unit 112 connected to the corresponding dual-purpose signal line 119. In addition, each detection channel A, B, C, D, and E is connected to a first power supply module 128 via a corresponding voltage divider resistor 123 in the adapter 120. The first power supply module 128 provides DC power to the detection channel A, B, C, D, and E.

[0049] In this embodiment, the first controller 121 is further configured to determine the test code array of the corresponding electrode plate 110 based on the simulated temperature signal detected by each sampled temperature detection unit 113, and to perform a consistency comparison between the test code array and the standard code array to identify the fault condition of each temperature detection unit 113 in the corresponding electrode plate 110. The standard code array is the code array when the electrode plate 110 is qualified. The adapter 120 may also include a reminder unit (not shown). When the first controller 121 detects a faulty temperature detection unit 113 in the electrode plate 110, it controls the reminder unit (not shown) to issue a first reminder message and instructs the electric field generator 130 to continue operating. For example, when the first controller 121 detects no faulty temperature detection unit 113 in the electrode plate 110, it controls the reminder unit (not shown) to illuminate green, and when a faulty temperature detection unit 113 in the electrode plate 110 is detected, it controls the reminder unit (not shown) to illuminate red.

[0050] In this embodiment, the first controller 121 is further configured to determine the number of faulty temperature detection units 113 in the electrode plate 110 when comparing the test code array with the standard code array, and to determine whether the electrode plate 110 needs to be replaced based on the number. For example, if the number exceeds a preset number (which can be set to a minimum of 1), it is determined that the electrode plate 110 needs to be replaced; if the number does not exceed the preset number, it is determined that the electrode plate 110 does not need to be replaced. The first controller 121 can also control a reminder unit (not shown) to issue a second reminder message and instruct the electric field generator 130 to stop working when it determines that the electrode plate 110 needs to be replaced. For example, when the first controller 121 determines that the electrode plate 110 needs to be replaced, it controls the reminder unit (not shown) to light up a red indicator light and flash, and simultaneously controls the reminder unit (not shown) to sound an alarm, such as a buzzer.

[0051] In this embodiment, the first communication unit 126 is configured to acquire digital signals output by multiple ADC units 122 and send the digital signals to the electric field generator 130. The electric field generator 130 is also configured to control and adjust the voltage of the alternating electrical signal provided to the multiple electrode units 112 of the electrode 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 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.

The VCC pin of the second connector 150 is also electrically connected to the VCC power line of the second power module 136, and the GND pin of the second connector 150 is grounded through the GND line of the second power module 136. The second power module 136 is also connected to and supplies power to the second controller 131 and the AC signal generator 132, respectively. 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 wires 1 to 4 of the second connector 150 for transmitting alternating electrical signals via the set of power switches 133. The set of power switches 133 includes multiple power switches 133, each corresponding to a specific electrode plate 110. Each power supply switch 133 is electrically connected to a corresponding conductor 1, 2, 3, 4 in the second connector 150 via an AC power line 134-1, 134-2, 134-3, 134-4 for transmitting alternating electrical signals, and is also electrically connected to a corresponding electrode plate 110 via corresponding conductors 1, 2, 3, 4 in the second connector 150, to deliver an alternating electrical signal to each electrode plate 110. 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. The power supply switches 133 include a first power supply switch 133-1, a second power supply switch 133-2, a third power supply switch 133-3, and a fourth power supply switch 133-4, which are electrically connected one-to-one with conductors 1 to 4 of the second connector 150.One end of the first power supply switch 133-1 is electrically connected to the AC signal generator 132 via the AC power line of the electric field generator 130, and the other end is electrically connected to the corresponding alternating signal transmission wire 1 in the second connector 150 via an AC power line 134-1, and then electrically connected to the alternating power line 127 at port X1 of the adapter 120 via the wire 1 of the second connector 150. The alternating power line 127 at port X1 of the adapter 120 is electrically connected to the first connector 140, and the first connector 140 at port X1 of the adapter 120 is electrically connected to the corresponding electrode plate 110, so as to control whether the AC signal generator 132 transmits alternating electrical signals to the electrode plate 110 electrically connected to port X1 of the adapter 120. The second power supply switch 133-2 is electrically connected at one end to the AC signal generator 132 via the AC power line of the electric field generator 130, and at the other end via an AC power line 134-2 to the corresponding conductor 2 transmitting alternating electrical signals in the second connector 150. The conductor 2 of the second connector 150 is then electrically connected to the alternating power line 127 at port Y1 of the adapter 120. The alternating power line 127 at port Y1 of the adapter 120 is electrically connected to the first connector 140. The first connector 140 at port Y1 of the adapter 120 is electrically connected to the corresponding electrode 110, thereby controlling whether the AC signal generator 132 supplies alternating electrical signals to the electrode 110 electrically connected to port Y1 of the adapter 120. The third power supply switch 133-3 is electrically connected at one end to the AC signal generator 132 via the AC power line of the electric field generator 130, and at the other end via an AC power line 134-3 to the corresponding conductor 3 transmitting alternating electrical signals in the second connector 150. The conductor 3 of the second connector 150 is then connected to the alternating power line 127 at port X2 of the adapter 120. The alternating power line 127 at port X2 of the adapter 120 is connected to the first connector 140. The first connector 140 at port X2 of the adapter 120 is connected to the corresponding electrode 110. This controls whether the AC signal generator 132 supplies alternating electrical signals to the electrode 110 electrically connected to port X2 of the adapter 120. The fourth power supply switch 133-4 is electrically connected at one end to the AC signal generator 132 via the AC power line of the electric field generator 130, and at the other end via an AC power line 134-4 to the corresponding wire 4 for transmitting alternating electrical signals in the second connector 150. The wire 4 of the second connector 150 is electrically connected to the alternating power line 127 at port Y2 of the adapter 120. The alternating power line 127 at port Y2 of the adapter 120 is electrically connected to the first connector 140. The first connector 140 at port Y2 of the adapter 120 is electrically connected to the corresponding electrode 110, so as to control whether the AC signal generator 132 transmits alternating electrical signals to the electrode 110 electrically connected to port Y2 of the adapter 120.

[0055] In this embodiment, the second controller 131 is further configured to determine the test code array of the corresponding electrode plate 110 based on the simulated temperature signal detected by each sampled temperature detection unit 113, and to perform a consistency comparison between the test code array and the standard code array to identify the fault condition of each temperature detection unit 113 in the corresponding electrode plate 110. The electric field generator 130 may also include an alert unit (not shown). When the second controller 131 detects a faulty temperature detection unit 113 in the electrode plate 110, it controls the alert unit (not shown) to issue a first alert message and continues to control the AC signal generator 132 to output an alternating electrical signal. For example, when the second controller 131 detects no faulty temperature detection unit 113 in the electrode plate 110, it controls the alert unit (not shown) to light up a green indicator light, while when a faulty temperature detection unit 113 in the electrode plate 110 is detected, it controls the alert unit (not shown) to light up a red indicator light.

[0056] In this embodiment, the second controller 131 is further configured to determine the number of faulty temperature detection units 113 in the electrode plate 110 when comparing the test code array with the standard code array, and to determine whether the electrode plate 110 needs to be replaced based on the number. For example, if the number exceeds a preset number (which can be set to a minimum of 1), it is determined that the electrode plate 110 needs to be replaced; if the number does not exceed the preset number, it is determined that the electrode plate 110 does not need to be replaced. The second controller 131 can also control the reminder unit (not shown) to issue a second reminder message and control the AC signal generator 132 to stop working when it determines that the electrode plate 110 needs to be replaced. For example, when the second controller 131 determines that the electrode plate 110 needs to be replaced, it controls the reminder unit (not shown) to light up a red indicator light and flash, and simultaneously controls the reminder unit (not shown) to sound an alarm (such as a buzzer).

[0057] In this embodiment, the first controller 121 or the second controller 131 is further configured to send the test code array to a host computer (not shown), so that the host computer (not shown) can compare the test code array with the standard code array to determine whether the electrode piece 110 is qualified. For example, the first controller 121 sends the test code array to the host computer (not shown) via the electric field generator 130, or directly to the host computer (not shown), so that the host computer (not shown) can compare the test code array with the standard code array to determine whether the electrode piece 110 is qualified; or, the second controller 131 sends the test code array to the host computer (not shown), so that the host computer (not shown) can compare the test code array with the standard code array to determine whether the electrode piece 110 is qualified. The host computer (not shown) may be connected to a display (not shown) to control the display (not shown) to display the test code array, the standard code array, and whether the electrode piece 110 is qualified. The host computer (not shown) is also connected to an alarm device to issue a reminder message when the electrode plate 110 is defective.

[0058] 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.

[0059] 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.

[0060] 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. The temperature detection units 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 112-1 is grounded at signal terminal 113B of unit 113, 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. 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.

[0061] When control switch 124-2 is closed, and control switches 124-1, 124-3, and 124-4 are all open, and the first bidirectional switching switch 125-1, the second bidirectional switching switch 125-2, the third bidirectional switching switch 125-3, the fourth bidirectional switching switch 125-4, and the fifth bidirectional switching switch 125-5 are all switched to their respective terminals 1, the temperature detection units 113 corresponding to electrode units 112-6 to 112-10 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. 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 112-6 is grounded, while the ground 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. 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 112-10.

[0062] When control switch 124-3 is closed, and control switches 124-1, 124-2, and 124-4 are all open, and the first bidirectional switching switch 125-1, the second bidirectional switching switch 125-2, the third bidirectional switching switch 125-3, the fourth bidirectional switching switch 125-4, and the fifth bidirectional switching switch 125-5 are all switched to their respective terminals 1, the temperature detection units 113 corresponding to electrode units 112-11 to 112-15 in the third row group are energized, 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. 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, it will not affect the resistance value of the temperature detection unit 113 corresponding to electrode unit 112-11. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-11 is effectively operating on the first detection channel A of this ADC unit 122. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-11. Similarly, the voltage value acquired on the second detection channel B in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-12. The voltage value acquired on the third detection channel C in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-13. The voltage value acquired on the fourth detection channel D in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-14. The voltage value acquired on the fifth detection channel E in this group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode units 112-15.

[0063] 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.

[0064] 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.

[0065] 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.

[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 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.

[0067] 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.

[0068] 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.

[0069] Specifically, during the use of the electrode pad 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can determine the test code array of the electrode pad 110 based on the temperature detection signal detected by each sampled temperature detection unit 113, and compare the test code array with the standard code array to monitor whether the electrode pad 110 is damaged, so as to replace the electrode pad 110 in time and avoid or reduce the risk of low-temperature burns to the patient. For example, the temperature sensor 114 in the temperature detection unit 113 is a negative temperature coefficient thermistor, which has the characteristic that the higher the temperature, the lower the resistance, and the lower the temperature, the higher the resistance. Since the electrode pad 110 is applied to the human body surface during use, and the human body surface temperature is generally between 36℃ and 37℃, a negative temperature coefficient thermistor with a temperature range of 0℃ to 50℃ 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.

[0070] 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):

[0071] VADC=(VCC-VD)×R / (Rz+R) (1)

[0072] 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 voltage divider resistor 123.

[0073] 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 can be obtained. 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 can be obtained. 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.

[0074] Since the ADC unit 122 acquires the voltage value of the temperature sensor 114, and the temperature sensor 114 detects different voltage values ​​for different temperatures, the voltage values ​​acquired by the ADC unit 122 can be reasonably segmented for differentiation. Simultaneously, this voltage value is converted into a corresponding code; that is, different voltage ranges correspond to different codes. Based on this code, the test code array of the electrode sheet 110 can be determined. The test code array includes at least one of a first code, a second code, and a third code. The first code indicates that the temperature detection unit 113 is in a normal state, the second code indicates that the temperature detection unit 113 is in an open-circuit state or an unset state, and the third code indicates that the temperature detection unit 113 is in a short-circuit state.

[0075] 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.

[0076] When the AD sampling value obtained by ADC unit 122 is greater than 0.5V and less than 3V, the corresponding code is the first code, such as 1; when the AD sampling value obtained by ADC unit 122 is less than or equal to 0.3V, the corresponding code is the third code, such as 0; when the AD sampling value obtained by ADC unit 122 is greater than or equal to 3.1V, the corresponding code is the second code, such as 2. Therefore, in the corresponding detection positions numbered 1 to 20 of 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.

[0077] refer to Figure 2 As shown, under normal circumstances, when the electrode plate 110 has 20 electrode units 112, and each electrode unit 112 corresponds to a temperature sensor 114 and a diode 115, that is, the corresponding detection positions numbered 1 to 20 of the electrode plate 110 all have temperature sensors 114, and the code for each is 1. Combining the 20 codes yields a 20-bit standard code array for the electrode plate 110: 11111 11111 11111 11111. When the temperature sensor 114 is open-circuited, assuming the temperature sensor 114 at detection position 1 is open-circuited, the resulting 20-bit test code array is 21111 11111 11111 11111. When the temperature sensor 114 is short-circuited, assuming the temperature sensor 114 at detection position 1 is short-circuited, the resulting 20-bit test code array is 01111 11111 11111 11111.

[0078] Based on the above coding rules, the quality of electrode 110 can be inspected during use to ensure timely replacement of electrode 110 and prevent low-temperature burns. The specific process is as follows:

[0079] Step 1: Provide at least one pair of qualified electrode pads 110 (since the electrode pads 110 are medical devices, each electrode pad 110 undergoes multiple tests before leaving the factory to ensure its qualification; therefore, the electrode pads 110 provided to the user are all qualified electrode pads 110). Connect at least one pair of qualified electrode pads 110 to the aforementioned adapter 120, and connect the aforementioned adapter 120 to the aforementioned electric field generator 130.

[0080] Step 2: Power on the electric field generator 130 to provide DC power VCC to the temperature detection units 113 in at least one pair of qualified electrode plates 110 for temperature detection. The ADC unit 122 in the adapter 120 collects the analog temperature signals detected by the temperature detection units 113 in at least one pair of qualified electrode plates 110 to obtain several AD sampling values. The first controller 121 in the adapter 120 obtains at least two sets of standard code arrays A1 and A2 according to the aforementioned encoding rules. The at least two sets of standard code arrays A1 and A2 can be stored in the adapter 120 and used as comparison codes.

[0081] Step 3: Turn off the power to the electric field generator 130 and place at least one pair of qualified electrode pads 110 on the body surface corresponding to the tumor portion of the patient.

[0082] Step 4: Power on the electric field generator 130 to provide DC power VCC to the temperature detection units 113 in at least one pair of qualified electrode pads 110 for temperature detection. Simultaneously, provide an alternating electrical signal to the electrode units 112 in the electrode pads 110 to form an alternating electric field between the paired electrode pads 110 for tumor electric field therapy. The ADC unit 122 in the adapter 120 acquires the temperature signals detected by the temperature detection units 113 of at least one pair of qualified electrode pads 110, obtaining several AD sampling values. The first controller 121 in the adapter 120 obtains at least two sets of detection code arrays B1' and B2' according to the aforementioned encoding rules.

[0083] Step 5: The first controller 121 in the adapter 120 compares the detection code arrays B1' and B2' with the corresponding standard code arrays A1 and A2 one by one. If the detection code arrays B1' and B2' are consistent with the standard code arrays A1 and A2, then steps 4 and 5 are repeated. If at least one detection code array B1' or B2' is inconsistent with the standard code arrays A1 and A2, then step 6 is performed.

[0084] Step 6: The adapter 120 confirms the number of abnormal temperature detection units 113 in the electrode plate 110 corresponding to the inconsistency detection code array B1' or / and B2', and determines whether the number of abnormal temperature detection units 113 in the corresponding electrode plate 110 exceeds the upper limit. If it does not exceed the upper limit, proceed to step 7; if it exceeds the upper limit, proceed to step 8.

[0085] Step 7: Continue repeating steps 4 and 5.

[0086] Step 8: The adapter 120 issues an alarm through its internal reminder unit (not shown) and simultaneously sends a corresponding signal to the electric field generator 130 through the first communication unit 126, so that the electric field generator 130 stops providing alternating electrical signals to the electrode unit 112 in the electrode plate 110, reminding the user to replace the corresponding electrode plate 110.

[0087] Step 9: Turn off the power to the electric field generator 130, remove the electrode plate 110 that needs to be replaced from the adapter 120, and connect the new electrode plate 110 to the adapter 120.

[0088] Step 10: Power on the electric field generator 130 to continue providing DC power VCC to the temperature detection unit 113 in the electrode plate 110 connected to the adapter 120 for temperature detection. The ADC unit 122 in the adapter 120 collects the temperature signal detected by the temperature detection unit 113 of the replaced qualified electrode plate 110, and obtains several AD sampling values. The first controller 121 in the adapter 120 obtains a new standard code array A1' or / and A2' according to the aforementioned encoding rules. At least one new standard code array A1' or / and A2' is compared with the corresponding standard code array A1 or / and A2 stored above. If the new standard code array A1' or / and A2' is consistent with the standard code array A1 or / and A2, then the electric field generator 130 is powered off. The source is to place the new electrode 110 on the corresponding body surface of the patient's tumor area, and then repeat steps four and five; if, after comparing the new standard code array A1' and / or A2' with the previously stored standard codes A1 and / or A2 one by one, there is at least one set of new standard code arrays A1' and / or A2' that are inconsistent with the previously stored and corresponding standard code arrays A1 and / or A2, then repeat steps nine and ten until the new standard code arrays A1' and / or A2' of the qualified electrode 110 that are replaced are consistent with the previously stored and corresponding standard code arrays A1 and / or A2.

[0089] It should be noted that in the above steps, the paired electrode pieces 110 can be electrode pieces 110 with the same design, that is, the standard coding arrays of the paired electrode pieces 110 are the same, that is, the standard coding arrays A1 and A2 are the same.

[0090] Steps one and two above can be replaced by the user inputting at least two sets of standard encoding arrays A1 and A2. At least two sets of standard encoding arrays A1 and A2 can be stored in the adapter 120 and used as comparison codes.

[0091] In step six above, the number of abnormal temperature detection units 113 in the corresponding electrode 110 is determined by comparing the inconsistent detection code arrays A1' and / or A2' with the corresponding standard code arrays A1 and A2 and finding that there are differences in the codes. For example, if A1' is compared with A1 and only the first code is different, then the number of abnormal temperature detection units 113 in the corresponding electrode 110 is 1; or if A1' is compared with A1 and only the last two codes are different, then the number of abnormal temperature detection units 113 in the corresponding electrode 110 is 2; and so on.

[0092] In step six above, the upper limit can be set to 1, meaning that if one temperature detection unit 113 on the electrode 110 is abnormal, step eight (alarm and replacement of electrode 110) will be performed. In other embodiments, the upper limit in step six above is not limited to 1, but can also be a positive integer close to the proportion of the number of temperature detection units 113 on the electrode 110.

[0093] In step eight above, the reminder unit (not shown) may include at least two indicator lights (not shown) corresponding one-to-one with each electrode piece 110, indicating the status of the corresponding electrode piece 110. When the electrode piece 110 does not need to be replaced, all indicator lights (not shown) are green; when the electrode piece 110 needs to be replaced, the indicator light (not shown) of the electrode piece 110 to be replaced is red. Alternatively, the status of the electrode piece 110 can be indicated by the indicator light (not shown) remaining constantly or flashing, indicating whether the electrode piece 110 does not need to be replaced or needs to be replaced.

[0094] In step eight above, the reminder unit (not shown) may also include a buzzer (not shown) to indicate the status of the electrode plate 110, which alerts the user simultaneously with the indicator light (not shown). When the electrode plate 110 does not need to be replaced, the buzzer (not shown) does not sound; when the electrode plate 110 needs to be replaced, the buzzer (not shown) sounds.

[0095] While comparing the detection code array with the standard code array in steps four, five, and six above, temperature monitoring is also performed simultaneously. The steps include the following:

[0096] Step 11: The first controller 121 in the adapter 120 calculates the digital temperature signal detected by the temperature detection unit 113 based on several AD sampling values, and determines whether the digital temperature signal exceeds the preset temperature. If the digital temperature signal detected by the temperature detection unit 113 of the electrode 110 exceeds the preset temperature, then proceed to step 12; if the digital temperature signals detected by the temperature detection unit 113 of the electrode 110 are all below the preset temperature, then continue to step 11.

[0097] Step 12: When the first controller 121 in the adapter 120 detects that the temperature detected by the temperature detection unit 113 of the electrode 110 exceeds the preset temperature, it sends a corresponding signal through the first communication unit 126 so that the electric field generator 130 reduces or shuts down the corresponding alternating current signal until the temperature detected by the temperature detection unit 113 of the corresponding electrode 110 is below the preset temperature. The preset temperature can be in the range of 39℃ to 41℃, preferably 40.5℃.

[0098] It should be noted that the above process is illustrated using the adapter 120 for quality monitoring of the electrode sheet 110 as an example. Alternatively, the electric field generator 130 can also perform quality monitoring of the electrode sheet 110, or the adapter 120 and the electric field generator 130 can each perform partial quality monitoring. Specific details will not be elaborated here. Furthermore, the number of electrode sheets 110, the number of electrode units 112 in each electrode sheet 110, and the setting of the sampling code are all illustrative examples and are not intended to limit this application.

[0099] Specifically, during the production process of electrode sheet 110, the first controller 121 of adapter 120 or the second controller 131 of electric field generator 130 can send the test code array of electrode sheet 110 to a host computer (not shown). The host computer (not shown) then compares the test code array with the standard code array to monitor whether each temperature detection unit 113 of electrode sheet 110 is properly connected, thereby determining whether electrode sheet 110 is qualified. This allows for the screening out of unqualified electrode sheets 110, ensuring that each temperature detection unit 113 of the electrode sheet 110 leaving the factory can perform normal testing. The standard code array includes at least the first code from the first code and the second code. The specific process is as follows:

[0100] Step 1: Provide a qualified electrode 110 and connect the electrode 110 to the aforementioned adapter 120. The aforementioned adapter 120 is connected to the aforementioned electric field generator 130. The aforementioned electric field generator 130 is also connected to a host computer (not shown, such as a computer). The host computer (not shown) is also connected to a display (not shown) so that the host computer (not shown) controls the display (not shown) to display the code array (i.e., standard code array) of the qualified electrode 110 and the code array (i.e., test code array) of the tested electrode 110' of the same batch and specifications as the qualified electrode 110.

[0101] Step 2: Power on the electric field generator 130 to provide DC power VCC to the temperature detection unit 113 of the qualified electrode 110 for temperature detection. The aforementioned adapter 120 obtains a set of standard code array A according to the aforementioned encoding rules. The standard code array A is routed from the aforementioned adapter 120 to the aforementioned electric field generator 130 to the host computer (not shown), and is finally stored in the host computer (not shown) as a standard code array for comparison.

[0102] Step 3: Provide a test electrode 110' of the same batch and specification as the qualified electrode 110, connect the test electrode 110' to the aforementioned adapter 120, and the aforementioned adapter 120 obtains a set of test code array B according to the aforementioned coding rules. The test code array B is routed by the aforementioned adapter 120 to the aforementioned electric field generator 130 to the host computer (not shown) and displayed on the display (not shown).

[0103] Step 4: The host computer (not shown) compares the test encoding array B with the standard encoding array A for consistency. If the test encoding array B and the standard encoding array A are consistent, proceed to step 5; if the test encoding array B and the standard encoding array A are inconsistent, proceed to step 6.

[0104] Step 5: The display (not shown) shows that the electrode 110' under test is "qualified". Place the electrode 110' under test in the good product area, and then repeat steps 3 and 4 to test the next electrode 110'.

[0105] Step 6: The display (not shown) shows that the electrode 110' under test is "unqualified". Place the electrode 110' under test in the defective product area, and then repeat steps 3 and 4 to test the next electrode 110'.

[0106] In step six above, while the display (not shown) shows "unqualified" for the tested electrode 110', the host computer (not shown) can also control an alarm (not shown) to alert the operator that the tested electrode 110' is "unqualified" and needs to be placed in the defective product area. The alarm (not shown) can be an audible alarm, a visual alarm, etc.

[0107] It should be noted that through the quality inspection steps of the electrode sheet 110 described above, standard code arrays of various qualified electrode sheets 110 can be stored in the host computer (not shown) to form a standard code array library of qualified electrode sheets 110. When a batch of electrode sheets 110' of the same specification is tested again, the corresponding standard code array A in the standard code array library can be called as the comparison code for the test of this batch of electrode sheets 110' and compared with the corresponding test code array B of the electrode sheet 110' to determine whether the batch of electrode sheets 110' is qualified.

[0108] The coding combination of the standard coding array A and the corresponding test coding array B of the electrode sheet 110' in the above steps is composed of multi-bit coding, and is not limited to the aforementioned. Figure 2 The 20-bit code combination corresponding to the electrode sheet 110 in the embodiment can be a combination of 13-bit, 24-bit, or other code arrangements.

[0109] The above steps are illustrated using the adapter 120 for quality inspection of the electrode sheet 110 as an example. The quality inspection of the electrode sheet 110 can also be performed by the electric field generator 130. Furthermore, the number of electrode sheets 110 that the adapter 120 can connect to, the number of electrode units 112 in each electrode sheet 110, and the setting of the sampling code are all illustrative examples and are not intended to limit this application.

[0110] 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.

[0111] Figure 6 The diagram shown is a schematic of a tumor electric field therapy system 300 according to a second embodiment of this application, whose electrode pads 310 also have corresponding open spaces and free ends. 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, adjacent electrode units 312 in the four electrode units 312 located in the first row and third column, the second row and third column, the third row and third column, and the fourth row and third column are connected by a column-directed connecting strip. At the same time, adjacent electrode units 312 in the four electrode units 312 located in the first row and fourth column, the second row and fourth column, the third row and fourth column, and the fourth row and fourth column are also connected by a column-directed connecting strip. 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.

[0112] It should be noted that for other related descriptions of the second embodiment, please refer to the related descriptions of the first embodiment, which will not be repeated here.

[0113] Second examples:

[0114] Figure 7 The diagram shown is a schematic representation of a tumor electric field therapy system 400 according to a third embodiment of this application. Figure 1 The tumor electric field therapy system 100 of the first embodiment shown differs in that the electrode sheet 410 of this embodiment has 13 electrode units 412, which are arranged in a spatial structure of five rows and five columns. Specifically, each of the first and fifth rows includes two electrode units 412, and the two electrode units 412 in each row are located in the second and fourth columns, respectively; each of the second to fourth rows includes three electrode units 412, and the three electrode units 412 in each row are located in the first, third, and fifth columns, respectively. 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 electrode unit 412 located in the first row and second column is connected to the electrode units 412 located in the second row and first column and the first row and third column respectively via a connecting strip (unlabeled); the electrode unit 412 located in the first row and fourth column is connected to the electrode units 412 located in the second row and third column and the first row and fifth column respectively via a connecting strip (unlabeled); the electrode unit 412 located in the fifth row and second column is connected to the electrode units 412 located in the fourth row and first column and the fourth row and third column respectively via a connecting strip (unlabeled); the electrode unit 412 located in the fifth row and fourth column is connected to the electrode units 412 located in the fourth row and third column and the fourth row and fifth column respectively via a connecting strip (unlabeled). Figure 8 for Figure 7 The circuit connection diagram of one electrode 410 and the adapter 420 of the tumor electric field therapy system 400 is shown below. Figure 8 As shown, the 13 electrode units 412 are configured in a three-row, five-column configuration in the circuit connection. The first two rows each contain 5 electrode units 412, and the third row contains 3 electrode units 412. Therefore, only three of the four control switches 424 are connected to the three grounding wires 418, while the other control switch 424 is left floating.

[0130] 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 the same dual-purpose signal line. While enabling the transmission of both alternating current signals and DC signals for temperature signal acquisition, as well as the acquired temperature detection signals, through the dual-purpose signal line, the number of conductive traces (grounding wire, dual-purpose signal line) laid on it is greatly reduced, thereby reducing the wiring difficulty of the substrate, simplifying the manufacturing process, reducing the weight of the substrate, and lowering manufacturing costs. At the same time, it is possible to achieve 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, thereby achieving quality inspection of the electrode sheet.

[0131] In the tumor electric field therapy system of this application, the same type of adapter can be adapted to a variety of electrode plates with different numbers of grounding wires and dual-purpose signal lines. Although the adapter may have a floating bidirectional switching switch and / or control switch for different electrode plates, its adaptability is improved.

[0132] Reference Figure 15 As shown, this application also provides a method for detecting the quality of electrode sheets, which includes the following steps:

[0133] S110: Determine the temperature detection signal of each electrode unit in the electrode sheet.

[0134] Specifically, refer to Figure 2 The switching unit is controlled to connect the dual-use signal line 119 corresponding to at least one column group in the corresponding electrode sheet 110 to the corresponding temperature sampling point; the control switch 124 corresponding to each row group is controlled to sample the analog temperature signal of the corresponding electrode unit 112 based on the corresponding temperature sampling point, so as to determine the temperature detection signal of each electrode unit 112 in each electrode sheet 110.

[0135] S120: Determine the test code array of the electrode sheet based on the temperature detection signal.

[0136] Specifically, the temperature detection signal is represented by a voltage value. The test code array for the electrode 110 is determined based on the temperature detection signal, including: determining the voltage range in which the voltage value falls; determining the code corresponding to the temperature detection unit 113 based on the voltage range in which the voltage value falls, wherein different voltage ranges correspond to different codes; and generating a test code array for the corresponding electrode 110 based on the code corresponding to each temperature detection unit 113. For example, the test code array includes at least one of a first code, a second code, and a third code, wherein the first code indicates that the temperature detection unit 113 is in a normal state, the second code indicates that the temperature detection unit 113 is in an open-circuit state or an unset state, and the third code indicates that the temperature detection unit 113 is in a short-circuit state.

[0137] S130: Compare the test code array with the standard code array to identify the fault condition of each temperature detection unit in the corresponding electrode sheet, or determine whether the corresponding electrode sheet is qualified.

[0138] Specifically, during the use of electrode pad 110, the test code array can be compared with the standard code array to identify the fault condition of each temperature detection unit 113 in the corresponding electrode pad 110, thereby realizing the quality inspection of electrode pad 110 during use. When a faulty temperature detection unit 113 in electrode pad 110 is identified, the tumor electric field therapy system 100 is also controlled to issue a first reminder message, and the electric field generator 130 is controlled to continue to work.

[0139] After comparing the test code array with the standard code array for consistency, the number of faulty temperature detection units 113 in the electrode pad 110 is determined, and the electrode pad 110 is judged to need to be replaced based on the number of faulty temperature detection units 113 in the electrode pad 110. When it is determined that the electrode pad 110 needs to be replaced, the tumor electric field therapy system 100 issues a second reminder message and controls the electric field generator 130 to stop working.

[0140] Specifically, during the production process of electrode sheet 110, the test code array can be compared with the standard code array to determine whether the corresponding electrode sheet 110 is qualified, thereby realizing the quality inspection of electrode sheet 110 during the production process. After determining whether the corresponding electrode sheet 110 is qualified, the test code array, standard code array, and the judgment result of whether the electrode sheet 110 is qualified can also be displayed, and a corresponding reminder message can be issued when the electrode sheet 110 is unqualified.
