Abstract
Description
Technical Field
[0001] The present application relates to tumor electric field therapy technology, and in particular to a tumor electric field therapy system and medium. Background Art
[0002] Tumor electric field therapy is a method that uses low-intensity, medium-high frequency alternating electric fields to prevent the formation of spindle microtubules in the mitosis process of certain tumor cells, inhibit the separation of intracellular organelles during cell division, and induce apoptosis of cells in the mitosis period, thereby achieving the effect of treating tumors.
[0003] Compared with traditional cancer treatments, tumor electric field therapy has an innovative mechanism of action. Some physiological characteristics of tumor cells, such as geometric shape and high-frequency mitosis, make them susceptible to tumor electric field therapy. Tumor electric field therapy disrupts the normal aggregation of tubulin by exerting directional forces on polar particles (such as macromolecules and organelles) within cells. These processes may lead to physical damage to the cell membrane and cell apoptosis. At the end of cell mitosis, the structural morphology of the cleavage furrow will lead to uneven distribution of the electric field around it. At the same time, under the influence of tumor electric field therapy, the electric field intensity at the cleavage furrow is significantly enhanced, and the charged substances in the cell move toward the cleavage furrow, which interferes with or even destroys the formation of the cell structure, and ultimately leads to cell division failure and apoptosis.
[0004] At present, the tumor electric field treatment system mainly includes an electric field generator, an adapter electrically connected to the electric field generator, and multiple pairs of electrode sheets electrically connected to the electric field generator through the adapter. The electric field generator transmits the alternating electric signal for tumor electric field treatment to each electrode sheet through the adapter, and then applies an alternating electric field to the patient's tumor site through the electrode sheet for tumor electric field treatment. Due to the different distribution of tumors, the intensity and coverage of the electric field are different for different sites of tumor electric field treatment. For example, when the site is the head, the electric field coverage is not very large, and two pairs of electrode sheets with 9 electrode units can cover it; when the site is the chest and abdomen, the electric field coverage is larger than the head, and the number of electrode units required is more than the head, such as using electrode sheets with 13, 20 or other more than 9 electrode units.
[0005] When performing tumor electric field therapy, the electric field applied to the patient will gather heat at the corresponding position of the electrode patch on the skin. In order to avoid low-temperature burns on the skin, a temperature sensor needs to be configured at each electrode unit to monitor the skin surface temperature at each electrode unit. Considering factors such as the location of the tumor distribution and the range that needs to be covered by tumor electric field therapy, when performing tumor electric field therapy, there are situations where two pairs of electrode patches with different numbers of electrode units need to be used in combination. Correspondingly, the number of temperature sensors corresponding to electrode patches with different numbers of electrode units is also different. For example, the number of temperature sensors of an electrode patch with 9 electrode units, an electrode patch with 13 electrode units, and an electrode patch with 20 electrode units are all different. The adapter needs to collect the analog temperature signals of 9 temperature sensors, 13 temperature sensors, and 20 temperature sensors respectively.
[0006] In the related art, the adapter collects the analog temperature signals of the temperature sensors on the electrode sheets connected to it with the same collection procedure, but this may result in interference with the analog temperature signals or failure to collect some temperature sensors. For example, the adapter collects 20 temperature sensors of a pair of electrode sheets with 20 electrode units according to the collection procedure for collecting 20 temperature sensors, and obtains 40 analog temperature signals. If the adapter collects the temperature sensors on a pair of electrode sheets with 13 electrode units connected to it with the same collection procedure, 40 analog temperature signals will be collected. Among these 40 analog temperature signals, only 26 analog temperature signals are analog temperature signals of the temperature sensors on the pair of electrode sheets with 13 electrode units, and the other 14 are interference signals. However, the adapter cannot identify which analog temperature signals are the required analog temperature signals. If the adapter collects temperature sensors of a pair of electrode sheets with 13 electrode units and a pair of electrode sheets with 20 electrode units connected to it according to the collection procedure for collecting 13 temperature sensors, then all temperature sensors on the electrode sheet with 13 electrode units can be collected by the adapter, but 7 temperature sensors on the electrode sheet with 20 electrode units cannot be collected by the adapter.

[0035] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.
[0036] Some of the first embodiments:
[0037] Figure 1FIG. 1 is a schematic diagram of a tumor electric field treatment system 100 according to a first embodiment of the present application. Figure 1 As shown, the tumor electric field treatment system 100 includes: at least one pair of electrode sheets 110, an adapter 120 electrically connected to the at least one pair of electrode sheets 110, and an electric field generator 130 electrically connected to the adapter 120. The at least one pair of electrode sheets 110 can be arranged in pairs on the patient's body surface, such as Figure 1 There are four electrode sheets 110, and every two electrode sheets 110 are arranged as a pair on the patient's body surface. The electric field generator 130 is used to supply power to at least one pair of electrode sheets 110, so that an alternating electric field for treating tumors is generated between at least one pair of electrode sheets 110. The adapter 120 is electrically connected between at least one pair of electrode sheets 110 and the electric field generator 130, and is used to transmit the alternating electric signal generated by the electric field generator 130 to at least one pair of electrode sheets 110. In other words, the electric field generator 130 is capable of generating an alternating electric signal, and the generated alternating electric signal is transmitted to each electrode sheet 110 through the adapter 120, so that an alternating electric field for treating tumors is generated between the same pair of electrode sheets 110, so as to apply an alternating electric field to the tumor site of the patient for tumor treatment.
[0038] like Figure 1 As shown, in this embodiment, the number of electrode sheets 110 is 4, each electrode sheet 110 includes a plurality of electrode units 112 of the same number, each electrode unit 112 is electrically connected to the adapter 120, and the number of electrode units 112 on each electrode sheet 110 is 20. In other embodiments, the tumor electric field treatment system 100 may also have more or fewer electrode sheets 110; in other embodiments, each pair of electrode sheets 110 has the same number of electrode units 112, and different pairs of electrode sheets 110 may have different numbers of electrode units 112; in other embodiments, the number of electrode units 112 on each electrode sheet 110 may be 9, 13, 19, etc.
[0039] Figure 2 for Figure 1 The circuit connection diagram of the electrode sheet 110 and the adapter 120 of the tumor electric field treatment system 100 is shown. 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 sheet 110 and an adapter 120. Figure 2 The arrangement of the electrode units 112 shown does not represent the arrangement of the electrode units 112 in a spatial structure. Figure 1 and Figure 2The electrode sheet 110 includes: a flexible circuit board 111, a plurality of electrode units 112 electrically connected to the flexible circuit board 111 at intervals, a plurality of temperature detection units 113, and a first cable 116 electrically connected to the flexible circuit board 111. The flexible circuit board 111 is embedded with multiple conductive traces, and the multiple conductive traces include multiple grounding wires 118 and multiple dual-purpose signal wires 119. The first cable 116 has multiple core wires (not shown), and each core wire is electrically connected to the multiple grounding wires 118 and the multiple dual-purpose signal wires 119 of the flexible circuit board 111 in a one-to-one correspondence. In this embodiment, the total number of grounding wires 118 and dual-purpose signal wires 119 embedded in the flexible circuit board 111 does not exceed 9, so the number of wires of the first cable 116 does not exceed 9.
[0040] The plurality of electrode units 112 are configured into a plurality of row groups and a plurality of column groups. In the present embodiment, each electrode sheet 110 is provided with 20 electrode units 112, and the 20 electrode units 112 are arranged in the order of 1 to 20 in the circuit connection, and are divided into four row groups and five column groups, that is, the 20 electrode units 112 are arranged in four row groups and five column groups 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 unit 112 and the temperature detection unit 113 are both welded on the flexible circuit board 111, and the electrode unit 112 is short-circuited with the signal terminal 113B of the corresponding temperature detection unit 113. Since the plurality of temperature detection units 113 are arranged one-to-one with the plurality of electrode units 112, the plurality of temperature detection units 113 are also arranged in four row groups and five column groups in the circuit connection. It should be noted that the arrangement here is to more clearly show the electrical connection between the electrode sheet 110 and the adapter 120, and does not represent the arrangement of the electrode unit 112 in the spatial structure. Figure 1The structure shown as an array may also be other structures, such as petal-shaped or scattered, and may be regular or irregular. In other embodiments, the 20 electrode units 112 may also be arranged in other ways. Of course, in other embodiments, the electrode sheet 110 may also have other numbers of electrode units 112. In short, the implementation of the present application is not limited by the number and arrangement of the electrode units 112 of the electrode sheet 110. The electrode unit 112 is configured to apply an alternating electrical signal to the patient's tumor site. The temperature detection unit 113 is configured to detect the temperature of the patient's body surface attached to the electrode sheet 110, that is, the temperature at the corresponding electrode unit 112, and output the temperature detection signal to an external device such as an adapter 120. In this embodiment, the multiplexed signal lines 119 of the flexible circuit board 111 are respectively arranged one by one with the multiple column groups of the electrode unit 112, and are configured to transmit the alternating electrical signal generated by the electric field generator 130 to each electrode unit 112 in the corresponding column group. That is, the electrode units 112 in the same column group are short-circuited through the same dual-purpose signal line 119 of the flexible circuit board 111, and the electrode units 112 in different column groups are connected in parallel through different dual-purpose signal lines 119 of the flexible circuit board 111. The dual-purpose signal line 119 of the flexible circuit board 111 is electrically connected to the first cable 116, and then electrically connected to the electric field generator 130 via the adapter 120. Further, the dual-purpose signal line 119 of the flexible circuit board 111 receives the alternating electric signal generated by the electric field generator 130 through the first cable 116 and the adapter 120.
[0041] The multiple grounding wires 118 are respectively arranged in one-to-one correspondence with the multiple row groups of the electrode unit 112, and the multiple grounding wires 118 are respectively used to short-circuit each corresponding temperature detection unit 113 in each row group to ground. That is, the grounding ends 113A of the multiple temperature detection units 113 in the same row group are short-circuited through the same grounding wire 118 of the flexible circuit board 111, and the grounding ends 113A of the temperature detection units 113 in different row groups are respectively connected in parallel through different grounding wires 118 of the flexible circuit board 111. During the time period of temperature detection, only one of the multiple grounding wires 118 is turned on at the same time, and the rest are disconnected.
[0042] Each of the multiplexed dual-purpose signal lines 119 is also configured to short-connect the signal end 113B of at most one temperature detection unit 113 in each row group to an external device for receiving a detection signal, wherein the signal end 113B of the temperature detection unit 113 connected to each of the multiplexed dual-purpose signal lines 119 is different from each other, so as to avoid the dual-purpose signal line 119 from subsequently outputting duplicate signals. That is, when the number of electrode units 112 in a row group is the same as the number of dual-purpose signal lines 119, each dual-purpose signal line 119 is electrically connected to a signal end 113B of a different temperature detection unit 113 in the row group; when the number of electrode units 112 in a row group is less than the number of dual-purpose signal lines 119, there is at least one dual-purpose signal line 119 that is not electrically connected to the signal end 113B of the temperature detection unit 113, and each of the remaining dual-purpose signal lines 119 is electrically connected to a signal end 113B of a different temperature detection unit 113 in the row group. In this embodiment, the external device for receiving the detection signal is an adapter 120. The signal ends 113B of the plurality of temperature detection units 113 in different column groups are respectively connected in parallel through different dual-purpose signal lines 119 of the flexible circuit board 111, and the signal ends 113B of the plurality of temperature detection units 113 in the same column group are short-circuited to the same dual-purpose signal line 119 of the flexible circuit board 111.
[0043] In this embodiment, when each electrode unit 112 is equipped with a temperature detection unit 113 for temperature detection, the above-mentioned circuit design is used to reduce the number of wires of the first cable 116, so as to avoid the cable becoming thicker and the cable becoming harder, thereby increasing the difficulty of fixing the cable; at the same time, the increase in the number of wires of the first cable 116 is avoided to affect the adhesion effect between the electrode sheet 110 and the body surface corresponding to the patient's tumor site. The grounding wire 118 and the dual-purpose signal line 119 embedded in the flexible circuit board 111 are 9 lines in total. Specifically, in this embodiment, the grounding wire 118 embedded in the flexible circuit board 111 is 4 lines, and the dual-purpose signal line 119 is 5 lines. The number of conductive lines electrically connected to the grounding wire 118 of the electrode sheet 110 in the tumor electric field treatment system 100 is related to the number of row groups M of the electrode unit 112, which is greater than or equal to the number of row groups of the electrode unit 112, and M is a positive integer. The number of conductive lines electrically connected to the dual-purpose signal lines 119 in the tumor electric field treatment system 100 is related to the number of column groups N of the electrode unit 112, which is greater than or equal to the number of column groups of the electrode unit 112, and N is a positive integer. The number of lines L embedded in the flexible circuit board 111 of the electrode sheet 110 is equal to the sum of the number of grounding lines 118 and the number of dual-purpose signal lines 119. In this embodiment, the number of grounding lines 118 is equal to the number of row groups M of the electrode unit 112; the dual-purpose signal lines 119 are equal to the number of column groups N of the electrode unit 112.
[0044] In terms of spatial structure, the plurality of electrode units 112 are arranged on the flexible circuit board 111 in a two-dimensional array. Figure 1 As shown, the electrode sheet 110 in this embodiment includes 20 electrode units 112 and 20 temperature detection units 113 corresponding to the electrode units 112. The 20 electrode units 112 are arranged in an array of four rows and six columns. The first row and the fourth row each have four electrode units 112, and the second row and the third row each have six electrode units 112. The four electrode units 112 in each of the first row and the fourth row are all located in each of the second to fifth columns, and the six electrode units 112 in each of the second row and the third row are all located in each of the first to sixth columns.
[0045] like Figure 1As shown, in terms of spatial structure, multiple electrode units 112 are connected in an asymmetric manner. For example, the 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 (not numbered), and the 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 connected by a column-directed connecting strip (not numbered). Each electrode sheet 110 has a free end. For example, at least one electrode unit 112 among the multiple electrode units 112 is connected to at most one other electrode unit 112. For example, the electrode units 112 located 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 are not connected by a connecting strip in the column direction, thereby forming an open space (not numbered), and the open space (not numbered) is adjustable. For example, the electrode unit 112 in the first row and second column is movable compared to the electrode units 112 in the second row and first column and the second row and second column. The positions of the electrode units 112 in the first column and the second row and the second column are movable compared to the electrode units 112 in the third row and the first column and the third row and the second column, and the positions of the electrode units 112 in the first column and the third row and the second column are movable compared to the electrode units 112 in the fourth row and the second column. Therefore, when the electrode sheet 110 is applied to the patient's body surface, the open space (unnumbered) between the electrode units 112 in the corresponding rows can be adjusted, so that the heat dissipation space of the corresponding electrode units 112 can be increased, thereby accelerating the heat dissipation and facilitating the patient to adjust the position of the electrode unit 112 based on the fever situation. Similarly, the electrode units 112 located in the first row and fourth column, the second row and fourth column, the second row and sixth column, the third row and fourth column, the third row and sixth column, and the fourth row and fourth column are not connected by connecting strips in the column direction, thereby forming an open space (unnumbered), and the open space (unnumbered) is adjustable, for example, the position of the electrode unit 112 in the first row and fourth column is movable compared to the electrode unit 112 in the second row and fourth column, the position of the electrode unit 112 in the second row and fourth column is movable compared to the electrode unit 112 in the third row and fourth column, the position of the electrode unit 112 in the second row and sixth column is movable compared to the electrode unit 112 in the third row and sixth column, and the position of the electrode unit 112 in the third row and fourth column is movable compared to the electrode unit 112 in the fourth row and fourth column, so that when the electrode sheet 110 is applied to the patient's body surface, the open space (unnumbered) between the electrode units 112 of the corresponding rows can be adjusted, so that the heat dissipation space of the corresponding electrode units 112 can be increased, thereby accelerating the heat dissipation, and at the same time facilitating the patient to adjust the position of the electrode unit 112 based on the fever situation.
[0046] Each electrode unit 112 can apply an alternating electric signal, and the electrode sheets 110 configured in pairs are used to apply an alternating electric field to the patient's tumor site. Optionally, the electrode unit 112 is a dielectric element, such as a ceramic sheet, which can also be a polymer dielectric layer composed of a polymer material. Each temperature detection unit 113 is arranged corresponding to an electrode unit 112 to detect the temperature at the corresponding electrode unit 112. Each temperature detection unit 113 can be arranged at any position of the corresponding electrode unit 112. In this embodiment, each electrode unit 112 is provided with a through hole 1121, and the through hole 1121 is suitable for installing the temperature detection unit 113. Specifically, the middle part of each electrode unit 112 has a through hole 1121, and each electrode unit 112 has a corresponding temperature detection unit 113 accommodated 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. 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 sensors other than thermistors. Each temperature sensor 114 is provided with a diode 115 in series. The diode 115 is connected in series with the temperature sensor 114 of the same electrode unit 112, which can prevent the reverse flow of current to prevent the detection signal from other electrode units 112 from affecting the temperature sensor 114.
[0047] like Figure 2As shown, the electrode sheet 110 of this embodiment includes 4 grounding wires 118, and each grounding wire 118 is used to ground the grounding ends 113A of the temperature detection units 113 in the same row group. The 4 grounding wires 118 of the electrode sheet 110 are respectively a first grounding wire 118-1, a second grounding wire 118-2, a third grounding wire 118-3 and a fourth grounding wire 118-4. In the 4 row groups 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 the temperature detection units 113 corresponding to the electrode units 112-1 to 112-5 in the first row group; the second grounding wire 118-2 is used to ground the temperature detection units 113 corresponding to the electrode units 112-6 to 112-10 in the second row group; the third grounding wire 118-3 is used to ground the temperature detection units 113 corresponding to the electrode units 112-11 to 112-15 in the third row group; the fourth grounding wire 118-4 is used to ground the temperature detection units 113 corresponding to the electrode units 112-16 to 112-20 in the fourth row group. It should be noted that these grounding wires 118 can be selectively closed or disconnected, which 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 ground pin through a control switch 124, which will be described in detail below. The above-mentioned "grounding the electrode unit 112" can refer to grounding the grounding terminals 114A of the temperature sensors 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 terminals 113A of the temperature detection units 113 corresponding to all electrode units 112 in each row group.
[0048] like Figure 2As shown, the electrode sheet 110 of this embodiment also includes 5 dual-purpose signal lines 119, one end of each dual-purpose signal line 119 is respectively connected to the signal end 113B of each electrode unit 112 and the corresponding temperature detection unit 113 in each column group, and the other end is connected to the adapter 120 for receiving the temperature detection signal and transmitting the alternating electric signal. That is to say, for each row group, each dual-purpose signal line 119 can choose to connect to the signal end 113B of one of the electrode units 112 and the corresponding temperature detection unit 113 or not connect to any electrode unit 112 in the row group and the signal end 113B of the corresponding temperature detection unit 113, so as to avoid the dual-purpose signal line 119 from subsequently outputting duplicate signals. Specifically, the 5 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 connected to the four electrode units 112, namely, electrode unit 112-1, electrode unit 112-6, electrode unit 112-11, and electrode unit 112-16, and the signal end 113B of the corresponding temperature detection unit 113; one end of the second dual-purpose signal line 119-2 is connected to the four electrode units 112, namely, electrode unit 112-2, electrode unit 112-7, electrode unit 112-12, and electrode unit 112-17, and the signal end 113B of the corresponding temperature detection unit 113; one end of the third dual-purpose signal line 119-3 is connected to the electrode units 112-3, 112-8, and 112-9, and the signal end 113B of the corresponding temperature detection unit 113. One end of the fourth dual-purpose signal line 119-4 is connected to the four electrode units 112, electrode unit 112-13, electrode unit 112-18 and the signal end 113B of the temperature detection unit 113 corresponding to each of them; one end of the fourth dual-purpose signal line 119-4 is connected to the four electrode units 112, electrode unit 112-4, electrode unit 112-9, electrode unit 112-14, electrode unit 112-19 and the signal end 113B of the temperature detection unit 113 corresponding to each of them; one end of the fifth dual-purpose signal line 119-5 is connected to the four electrode units 112, electrode unit 112-5, electrode unit 112-10, electrode unit 112-15, electrode unit 112-20 and the signal end 113B of the temperature detection unit 113 corresponding to each of them. In short, each dual-purpose signal line 119 short-circuits the electrode units 112 and the signal end 113B of the temperature detection unit 113 corresponding to each of them in the same column group in parallel and is used to connect to an external device. It should be noted that these dual-purpose signal lines 119 can selectively transmit alternating electrical signals or receive temperature detection signals, which can be achieved by connecting each dual-purpose signal line 119 in series with a bidirectional switch 125 and coordinating the closing or opening of the ground line 118.That is, after the signal end 113B of each temperature detection unit 113 in each column group is short-circuited with the corresponding electrode unit 112, they are connected to the switching unit (not labeled) through a dual-purpose signal line 119. The switching unit (not labeled) includes a plurality of bidirectional switches 125. Each bidirectional switch 125 is configured to switch the dual-purpose signal line 119 to connect to the temperature sampling point (not labeled) or the alternating power line 127, so that when the dual-purpose signal line 119 is connected to the temperature sampling point (not labeled), the control switch 124 is configured to control the temperature sampling point 112. The switching state is so that the temperature detection signal detected by the corresponding temperature detection unit 113 in each row group is sampled based on the temperature sampling point (unnumbered), and the sampled temperature detection signal detected by each temperature detection unit 113 is used to determine the coding array of the corresponding electrode sheet 110, and the type of the corresponding electrode sheet 110 is determined by the coding array, and when the dual-purpose signal line 119 is connected to the alternating power line 127, the electrode unit 112 of at least one column group is applied with an alternating electric signal based on the alternating power line 127, which will be described in detail below.
[0049] The multiple grounding wires 118 and the multiplexed signal wires 119 are conductive traces embedded in the flexible circuit board 111. The flexible circuit board 111 is electrically connected to the first cable 116. The multiple grounding wires 118 and the multiplexed signal wires 119 embedded in the flexible circuit board 111 are electrically connected to corresponding wires (not shown) in the first cable 116 one by one.
[0050] The tumor electric field treatment system 100 of this embodiment includes at least one pair of the above-mentioned electrode sheets 110, an adapter 120 electrically connected to the electrode sheets 110, and an electric field generator 130 electrically connected to the adapter 120. The adapter 120 is connected between the electrode sheets 110 and the electric field generator 130. The electric field generator 130 provides an alternating electric signal to a plurality of electrode units 112 of the electrode sheet 110 via the adapter 120 and the dual-purpose signal line 119 of the electrode sheet 110, or is used to receive the temperature detection signal output by the temperature detection unit 113 corresponding to the plurality of electrode units 112. The adapter 120 transmits the alternating electric signal generated by the electric field generator 130 to the dual-purpose signal line 119 of the electrode sheet 110, and is also configured to receive the temperature detection signal output by the multiplex dual-purpose signal line 119 of the electrode sheet 110.

The adapter 120 also includes multiple circuit lines (unnumbered), which are electrically connected to multiple ground lines 118 and multiple dual-purpose signal lines 119 in the flexible circuit board 111 of the electrode sheet 110 through the first cables 116 of the corresponding electrode sheet 110. The multiple circuit lines (unnumbered) include an alternating power line 127 that transmits an alternating electrical signal to the corresponding electrode sheet 110 and is electrically connected to the multiplexed signal line 119 in the flexible circuit board 111 of the corresponding electrode sheet 110, multiple circuit lines (unnumbered) that are electrically connected one-to-one with the multiplexed signal line 119 in the flexible circuit board 111 of the corresponding electrode sheet 110 and are used to supply power to each temperature detection unit 113 of the electrode sheet 110 or transmit the temperature detection signal of the electrode sheet 110, and multiple circuit lines (unnumbered) that are electrically connected one-to-one with the multiple ground lines 118 in the flexible circuit board 111 of the corresponding electrode sheet 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 sheets 110. Optionally, the number of groups of control switches 124 and the number of groups of bidirectional switching switches 125 are both the same as the number of electrode sheets 110. The electrical connection between an electrode sheet 110 having 20 electrode units 112 and an adapter 120 is described in detail below.

[0062] The following will refer to Figures 2 to 4 The working principle of the tumor electric field treatment system 100 of this embodiment is described in detail.
[0063] Specifically, when it is necessary to detect the temperature of each electrode unit 112 of a certain electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls one end of each of the multiple bidirectional switching switches 125 of a group of bidirectional switching switches 125 electrically connected to the electrode sheet 110 to be turned on and the two ends to be turned off, so as to disconnect the alternating electric signal applied to the electrode sheet 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 of a group of control switches 124 electrically connected to the electrode sheet 110 to be turned on in sequence in a time-sharing manner. At this time, the temperature detection signals collected by each temperature detection unit 113 corresponding to each electrode unit 112 of each row group of the electrode sheet 110 can be collected in a time-sharing manner in a sequential manner through multiple detection channels A, B, C, D, and E of a group of ADC units 122 corresponding to the electrode sheet 110. Each detection channel A, B, C, D, E of each group of ADC units 122 only collects the temperature detection signal of the temperature detection unit 113 corresponding to each electrode unit 112 of the electrode sheet 110 in the same row group at the same time, and the above temperature detection signal can be represented by a voltage value. Among the four control switches 124 in a group of control switches 124 corresponding to the electrode sheet 110, only one control switch 124 can be turned on at the same time, and the other three are turned off. The five bidirectional switching switches 125 of a group of bidirectional switching switches 125 corresponding to the group of ADC units 122 are all switched to their respective ends 1 so that each dual-purpose signal line 119 of the electrode sheet 110 is electrically connected to the corresponding detection channel A, B, C, D, E of the corresponding ADC unit 122 in a one-to-one correspondence and turned on. With such a setting, the group of ADC units 122 can collect the voltage values of all temperature detection units 113 corresponding to each electrode unit 112 in the same row group that is short-circuited with a ground line 118 corresponding to the turned-on control switch 124.
[0064] Specifically, when the control switch 124-1 is closed, the control switches 124-2, 124-3 and 124-4 are all opened, and the first two-way switch 125-1, the second two-way switch 125-2, the third two-way switch 125-3, the fourth two-way switch 125-4 and the fifth two-way switch 125-5 are all switched to their respective 1 terminals, the temperature detection units 113 corresponding to the electrode units 112-1 to 112-5 of the first row group are powered on, and the temperature detection units 113 corresponding to the electrode units 112-6 to 112-20 of the remaining row groups are powered off, and the signal terminals of the temperature detection units 113 corresponding to the electrode units 112-1, 112-6, 112-11 and 112-16 of the group of ADC units 122 are short-circuited on the first detection channel A. 113B, since only the grounding terminal 113A of the temperature detection unit 113 corresponding to the electrode unit 112-1 is connected to the ground, and the grounding terminals 113A of the temperature detection units 113 corresponding to the electrode units 112-6, 112-11, and 112-16 are disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, the remaining temperature detection units 113 in the same row group will not affect the resistance value of the temperature detection unit 113 corresponding to the electrode unit 112-1, so only the temperature detection unit 113 corresponding to the electrode unit 112-1 is effectively operated on the first detection channel A of the ADC unit 122 of the group, and 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 the electrode unit 112-1. Similarly, the voltage value collected on the second detection channel B in the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-2. The voltage value collected on the third detection channel C in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-3. The voltage value collected on the fourth detection channel D in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-4. The voltage value collected on the fifth detection channel E in the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-5.
[0065] When the control switch 124-2 is closed, the control switches 124-1, 124-3 and 124-4 are all opened, and the first two-way switch 125-1, the second two-way switch 125-2, the third two-way switch 125-3, the fourth two-way switch 125-4 and the fifth two-way switch 125-5 are all switched to their respective ends 1, the temperature detection units 113 corresponding to the electrode units 112-6 to 112-10 of the second row group are powered on, and the temperature detection units 113 corresponding to the electrode units 112-1 to 112-5 and the electrode units 112-11 to 112-20 of the remaining row groups are powered off, and the temperature detection units 113 corresponding to the electrode units 112-1, 112-6, 112-11 and 112-16 of the first detection channel A in the group of ADC units 122 are short-circuited. At the signal end 113B of the temperature detection unit 113, since only the grounding end 113A of the temperature detection unit 113 corresponding to the electrode unit 112-6 is connected to the ground, and the grounding ends 113A of the temperature detection units 113 corresponding to the 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 remaining temperature detection units 113 in the same row group will not affect the resistance value of the temperature detection unit 113 corresponding to the electrode unit 112-6. Therefore, on the first detection channel A of the ADC unit 122 of this group, only the temperature detection unit 113 corresponding to the electrode unit 112-6 is effectively operating. 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 the electrode unit 112-6. Similarly, the voltage value collected on the second detection channel B in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-7. The voltage value collected on the third detection channel C in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-8. The voltage value collected on the fourth detection channel D in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-9. The voltage value collected on the fifth detection channel E in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-10.
[0066] When the control switch 124-3 is closed, the control switches 124-1, 124-2 and 124-4 are all opened, and 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 are all switched to their respective ends 1, the temperature detection units 113 corresponding to the electrode units 112-11 to 112-15 of the third row group are powered on, and the temperature detection units 113 corresponding to the electrode units 112-1 to 112-10 and the electrode units 112-16 to 112-20 of the remaining row groups are powered off, and the temperature detection units 113 corresponding to the electrode units 112-1, 112-6, 112-11 and 112-16 of the first detection channel A in the group of ADC units 122 are short-circuited. At the signal end 113B of the temperature detection unit 113, since only the grounding end 113A of the temperature detection unit 113 corresponding to the electrode unit 112-11 is connected to the ground, and the grounding ends 113A of the temperature detection units 113 corresponding to the electrode units 112-1, 112-6 and 112-16 are disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, the remaining temperature detection units 113 located in the same row group will not affect the resistance value of the temperature detection unit 113 corresponding to the electrode unit 112-11. Therefore, on the first detection channel A of the ADC unit 122 of this group, only the temperature detection unit 113 corresponding to the electrode unit 112-11 is effectively operating. 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 the electrode unit 112-11. Similarly, the voltage value collected on the second detection channel B in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-12. The voltage value collected on the third detection channel C in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-13. The voltage value collected on the fourth detection channel D in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-14. The voltage value collected on the fifth detection channel E in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-15.
[0067] When the control switch 124-4 is closed, the control switches 124-1, 124-2 and 124-3 are all disconnected, and the first two-way switch 125-1, the second two-way switch 125-2, the third two-way switch 125-3, the fourth two-way switch 125-4 and the fifth two-way switch 125-5 are all switched to their respective 1 ends, the temperature detection units 113 corresponding to the electrode units 112-16 to 112-20 of the fourth row group are powered on, and the temperature detection units 113 corresponding to the electrode units 112-1 to 112-15 of the remaining row groups are powered off, and the signal ends 113B of the temperature detection units 113 corresponding to the electrode units 112-1, 112-6, 112-11 and 112-16 are short-circuited on the first detection channel A of the group of ADC units 122 , since only the grounding terminal 113A of the temperature detection unit 113 corresponding to the electrode unit 112-16 is connected to the ground, and the grounding terminals 113A of the temperature detection units 113 corresponding to the electrode units 112-1, 112-6, and 112-11 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 remaining temperature detection units 113 in the same row group will not affect the resistance value of the temperature detection unit 113 corresponding to the electrode unit 112-16, so only the temperature detection unit 113 corresponding to the electrode unit 112-16 on the first detection channel A of the group of ADC units 122 is effectively running, and 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 the electrode unit 112-16. Similarly, the voltage value collected on the second detection channel B in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-17. The voltage value collected on the third detection channel C in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-18. The voltage value collected on the fourth detection channel D in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-19. The voltage value collected on the fifth detection channel E in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-20.
[0068] Thus, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can collect the temperature detection signals of the temperature detection units 113 corresponding to all the electrode units 112 of the electrode sheet 110 by controlling a group of bidirectional switching switches 125 and a group of control switches 124 that are electrically connected to a certain electrode sheet 110. That is, the switching unit (unnumbered) 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 (unnumbered) at the same time, and by configuring the switch states of the corresponding control switches 124, 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 (unnumbered). Similarly, the temperature detection signals of the temperature detection units 113 of each electrode unit 112 of other electrode sheets 110 can be obtained.
[0069] The first controller 121 or the second controller 131, the plurality of ADC units 122 and the plurality of bidirectional switches 125 can automatically perform operations through pre-programmed program codes. For example, the first controller 121 or the second controller 131 first controls all the bidirectional switches 125 in the corresponding group of bidirectional switches 125 to switch to end 1 so that all ends 1 of the bidirectional switches 125 are turned on and all ends 2 are turned off so that all the dual-purpose signal lines 119 of the corresponding electrode sheet 110 are electrically connected to the corresponding group of ADC units 122, and then closes the first control switch 124-1 in the corresponding group of control switches 124, and disconnects the remaining second control switches 124-2 to fourth control switches 124-4 in the group of control switches 124. During this period, the ADC units 122 in the corresponding group of control switches 124 are turned on and off. Each detection channel A, B, C, D, E of the ADC unit 122 obtains the temperature detection signal of each temperature detection unit 113 corresponding to each electrode unit 112 located in the first row group in the corresponding electrode sheet 110 and converts it into a digital signal and stores it in a separately set memory. Then, after a preset interval, the first controller 121 or the second controller 131 closes the second control switch 124-2 in the group of control switches 124 and disconnects the first control switch 124-1, the third control switch 124-3 and the fourth control switch 124-4 in the group of control switches 124. During this period, each detection channel A, B, C, D, E of the ADC unit 122 obtains the temperature detection signal of each temperature detection unit 113 corresponding to each electrode unit 112 located in the second row group. In this way, each control switch 124 in the group of control switches 124 is turned on separately in turn, and the temperature detection signal of all the temperature detection units 113 on the electrode sheet 110 can be obtained. Similarly, the temperature detection signal of all the temperature detection units 113 on at least one pair of electrode sheets 110 is obtained through this operation.
[0070] It should be noted that, in other embodiments, a group of bidirectional switching switches 125 and a group of control switches 124 electrically connected to a certain electrode sheet 110 can be controlled by the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 to collect the temperature detection signals of the temperature detection units 113 corresponding to some electrode units 112 of the electrode sheet 110 in the same temperature collection time period. For example, when only the first bidirectional switch 125-1 is switched to its 1 end, the first control switch 124-1 can be controlled to be closed first, and the second control switch 124-2, the third control switch 124-3 and the fourth control switch 124-4 are all disconnected. At this time, only the temperature detection unit 113 corresponding to the electrode unit 112-1 of the first row group is energized, and the signal end 113B of the temperature detection unit 113 corresponding to the electrode unit 112-1 is short-circuited on the first detection channel A in the group of ADC units 122. Therefore, the group of ADC units 122 will detect the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-1; then, the second control switch 124-2 is controlled to be closed, and the first control switch 124-1, the third control switch 124-3 and the fourth control switch 124-4 are all disconnected. The control switches 124-4 are all disconnected, at which time the group of ADC units 122 will detect the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-6; then the third control switch 124-3 is controlled to be closed, the first control switch 124-1, the second control switch 124-2 and the fourth control switch 124-4 are all disconnected, at which time the group of ADC units 122 will detect the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-11; finally, the fourth control switch 124-4 is controlled to be closed, the first control switch 124-1, the second control switch 124-2 and the third control switch 124-3 are all disconnected, at which time the group of ADC units 122 will detect the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-16. Thus, in the same acquisition time period, only the temperature detection signal of the temperature detection unit 113 corresponding to the electrode unit 112 of one column group can be sampled. Similarly, in other acquisition time periods, the temperature detection signals of the temperature detection units 113 corresponding to the electrode units 112 of other column groups can be sampled. That is, the switching unit (not labeled) is configured to switch the dual-purpose signal line 119 corresponding to each column group to be connected to the corresponding temperature sampling point (not labeled), and the temperature detection signal detected by each temperature detection unit 113 in each column group is sampled respectively by configuring the switch state of the corresponding control switch 124. It should be noted that in other embodiments, the temperature detection signal of the temperature detection unit 113 corresponding to the electrode unit 112 of two column groups, three column groups or four column groups can also be sampled within the same sampling time period, which will not be described in detail here.
[0071] Specifically, when it is necessary to apply an alternating electric signal to each electrode unit 112 of a certain electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls the two ends of each of the multiple bidirectional switch 125 of a group of bidirectional switch 125 electrically connected to the electrode sheet 110 to be turned on and one end to be turned off, and controls a power switch 133 electrically connected to the electrode sheet 110 to be turned on, and at this time, the second controller 131 of the electric field generator 130 controls the AC signal generator 132 to apply an alternating electric signal to each electrode unit 112 of the electrode sheet 110 through the alternating power line 127, and the voltage or current of the applied alternating electric signal is adjustable. That is, the switching unit (not numbered) is configured to switch the dual-purpose signal lines 119 corresponding to at least two column groups to be connected to the alternating power line 127 at the same time, so that the electrode units 112 of at least two column groups are simultaneously applied with alternating electric signals based on the alternating power line 127.
[0072] It should be noted that, in other embodiments, a group of bidirectional switches 125 electrically connected to a certain electrode sheet 110 can be controlled by the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 to apply alternating electric signals to some electrode units 112 of the electrode sheet 110 in 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 two ends of only the first two-way switch 125-1 of the plurality of two-way switches 125 electrically connected to the electrode sheet 110 to be turned on and one end to be turned off, and controls a power switch 133 electrically connected to the electrode sheet 110 to be turned on, at which time the second controller 131 of the electric field generator 130 controls the AC signal generator 132 to apply an alternating electric signal to the first column group electrode unit 112-1, electrode unit 112-6, electrode unit 112-11, and electrode unit 112-16 of the electrode sheet 110 through the alternating power line 127, and the voltage or current of the applied alternating electric signal is adjustable. That is, the switching unit (not numbered) is configured to switch the dual-purpose signal line 119 corresponding to each column group to be connected to the alternating power line 127 respectively, so that the electrode unit 112 of each column group is simultaneously applied with an alternating electric signal based on the alternating power line 127. It should be noted that, in other embodiments, alternating electrical signals may be applied to two-column groups, three-column groups, or four-column groups of electrode units 112 simultaneously in the same time period, which will not be described in detail here.
[0073] Specifically, when it is necessary to determine the type of the electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can first sample the temperature detection signal detected by each temperature detection unit 113 in the aforementioned manner, and then determine the encoding array of the corresponding electrode sheet 110 based on the sampled temperature detection signal detected by each temperature detection unit 113, and determine the type of the corresponding electrode sheet 110 according to the encoding array. For example, the temperature sensor 114 in the temperature detection unit 113 is a thermistor with a negative temperature coefficient, and its characteristic is that the higher the temperature, the smaller the resistance, and the lower the temperature, the larger the resistance. Since the electrode sheet 110 is attached to the human body surface when in use, and the human body surface temperature is generally 36°C to 37°C, a thermistor with a negative temperature coefficient in the temperature range of 0°C to 50°C can be selected. For example, you can choose a thermistor model NCP18XH103D03RB. When the sensed temperature is 0°C, the corresponding resistance is about 27.45KΩ; when the sensed temperature is 25°C, the corresponding resistance is about 10.0KΩ; when the sensed temperature is 50°C, the corresponding resistance is about 4.16KΩ.
[0074] 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 turn. 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 collection channel, that is, the voltage divided by the temperature sensor 114, the diode 115 and the voltage divider resistor 123, and obtains an AD sampling value, that is, a voltage value (voltage value of the thermistor), as shown in the following formula (1):
[0075] VADC=(VCC-VD)×R / (Rz+R) (1)
[0076] Among them, VADC is the AD sampling value, that is, the voltage value, VCC is also used to indicate the voltage of the DC power supply, VD is the voltage drop of the diode 115, R is the resistance value of the thermistor, and Rz is the resistance value of the voltage divider resistor.
[0077] Assuming that the voltage drop VD of the diode 115 is 0.3V and the resistance Rz of the voltage divider resistor 123 is 10KΩ, when the temperature sensed by the temperature sensor 114 is 0°C, the corresponding resistance is about 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 the temperature sensor 114 is 25°C, the corresponding AD sampling value V0=(3.3-0.3)×27.45 / (10+27.45)=2.20V can be obtained. The resistance value is about 10.0KΩ, and 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 the temperature sensor 114 is 50℃, the corresponding resistance value is about 4.16KΩ, and based on formula (1), the corresponding AD sampling value V50=(3.3-0.3)×4.16 / (10+4.16)=0.88V can be obtained. When the temperature sensor 114 is disconnected, for example, the temperature sensor 114 is abnormally welded or the temperature sensor 114 is open, the corresponding AD sampling value can be 3.3V. When the temperature sensor 114 and the diode 115 are short-circuited, the corresponding AD sampling value can be 0V.
[0078] Since the ADC unit 122 collects the voltage value of the temperature sensor 114, and the temperature sensor 114 detects different temperatures with corresponding different voltage values, the voltage value collected by the ADC unit 122 can be reasonably segmented for distinction, and the voltage value can be converted into a corresponding code to identify the type of the electrode sheet 110, that is, the number of electrode units 112 on the electrode sheet 110.
[0079] Specifically, taking the example that the temperature sensor 114 senses a temperature within the range of 0°C to 50°C, and the AD sampling value obtained by the ADC unit 122, that is, the voltage value range is 0.88V to 2.20V, considering the detection error factor, etc., the voltage value range can be appropriately enlarged to 0.5V to 3V.
[0080] When the AD sampling value obtained by the ADC unit 122 is greater than 0.5V and less than 3V, the corresponding acquisition code is 1; when the AD sampling value obtained by the ADC unit 122 is less than or equal to 0.3V, the corresponding acquisition code is 0; when the AD sampling value obtained by the ADC unit 122 is greater than or equal to 3.1V, the corresponding acquisition code is 2. Therefore, in the corresponding detection positions numbered 1 to 20 of the electrode sheet 110, if the temperature sensor 114 is short-circuited, the corresponding code is 0, that is, the third code; if there is a temperature sensor 114, the corresponding code is 1, that is, the first code; if there is no temperature sensor 114 or the temperature sensor 114 is disconnected, the corresponding code is 2, that is, the second code.
[0081] refer to Figure 5As shown, when sampling is performed, no matter which type of electrode sheet 110 is used (i.e., the number of electrode units 112 or temperature sensors 114 of the electrode sheet 110 is any number less than or equal to 20), the ADC unit 122 obtains 20 AD sampling values each time, and after each acquisition is completed, a 20-bit coding array is formed based on the 20 AD sampling values. Each type of electrode sheet 110 has a corresponding coding array, so the type of the electrode sheet 110 can be automatically identified through the coding array.
[0082] The first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can determine the coding array of the corresponding electrode sheet 110 according to a number of AD sampling values, and determine the type of the corresponding electrode sheet 110 according to the coding array. Figure 2 As shown, when the electrode sheet 110 has 20 electrode units 112, each electrode unit 112 corresponds to a temperature sensor 114 and a diode 115, that is, the corresponding detection positions numbered 1 to 20 of the electrode sheet 110 all have a temperature sensor 114, and the codes are all 1, the 20 codes are combined to obtain a 20-bit code array 11111 11111 11111 11111.
[0083] like Figure 8 As shown, when the electrode sheet 310 has 13 electrode units 312 and 13 temperature detection units 313, the 13 electrode units 312 and the 13 temperature detection units 313 are arranged in three rows and five columns in the circuit connection, and the 13 electrode units 312 and the 13 temperature detection units 313 are arranged sequentially, and a corresponding position of the 13 temperature detection units 313 is short-circuited with a wire (unnumbered), that is, a wire (unnumbered) is arranged at the intersection of the three rows and four columns in the circuit connection to short-circuit the ground terminal 313A of the temperature detection unit 313 in the same group, and at the same time short-circuit the signal terminal 313B of the temperature detection unit 313 in the same column group. Each temperature detection unit 313 includes a temperature sensor 314 and a diode 315, and the corresponding detection positions are numbered 1 to 13, that is, the corresponding detection positions of the electrode sheet 310 numbered 1 to 13 all have temperature sensors 314, and the codes are all 1. Different from the electrode sheet 110 having 20 electrode units 112, the next detection position (that is, the corresponding detection position numbered 14) has no electrode unit 312 (no temperature sensor 314) set, and is short-circuited in parallel by wires (unnumbered), and the corresponding code is 0; the corresponding detection positions numbered 15 to 20 have no electrode unit 312 (no temperature sensor 314) set, nor are they short-circuited in parallel by wires (unnumbered), and are in a disconnected state, and the corresponding code is 2. Therefore, the 20-bit codes are combined to obtain a 20-bit code array of 11111 11111 11102 22222.
[0084] like Fig.13 As shown, when the electrode sheet 710 has 9 electrode units 712 and 9 temperature detection units 713, the 9 electrode units 712 and the 9 temperature detection units 713 are arranged in two rows and five columns in the circuit connection, and the 9 electrode units 712 and the 9 temperature detection units 713 are arranged sequentially, and a corresponding position of the 9 temperature detection units 713 is short-circuited with a wire (unnumbered), that is, a wire (unnumbered) is arranged at the intersection of two rows and five columns in the circuit connection to short-circuit the ground terminal 713A of the temperature detection unit 713 in the same row group, and at the same time short-circuit the signal terminal 713B of the temperature detection unit 713 in the same column group. Each temperature detection unit 713 includes a temperature sensor 714 and a diode 715, and the corresponding detection positions are numbered 1 to 9, that is, the corresponding detection positions numbered 1 to 9 of the electrode sheet 710 all have temperature sensors 714, and the codes are all 1. Different from the electrode sheet 110 having 20 electrode units 112, the next detection position (that is, the corresponding detection position numbered 10) has no electrode unit 712 (no temperature sensor 714) set, and is short-circuited by a wire (unnumbered), and the corresponding code is 0; the corresponding detection positions numbered 11 to 20 have no electrode unit 712 (no temperature sensor 714) set, and are not short-circuited by a wire (unnumbered), and are in a disconnected state, and the corresponding code is 2. Therefore, the 20-bit codes are combined to obtain a 20-bit code array 1111111110 22222 22222.
[0085] When the adapter 120 is not connected to the electrode sheet 110 , the ADC unit 122 samples the voltage of the DC power supply VCC, which is 3.3V. Therefore, the 20-bit code array is 22222 22222 22222 22222.
[0086] Based on the above rules, it can be known that: for an electrode sheet with 1 electrode unit and 1 temperature detection unit, the corresponding coding array is 10222 22222 22222 22222; for an electrode sheet with 2 electrode units and 2 temperature detection units, the corresponding coding array is 11022 22222 22222 22222; for an electrode sheet with 3 electrode units and 3 temperature detection units, the corresponding coding array is 11102 22222 22222 22222; for an electrode sheet with 4 electrode units and 4 temperature detection units, the corresponding coding array is 11110 222222222222 22222; for an electrode sheet with 5 electrode units and 5 temperature detection units, the corresponding coding array is 11111 02222 22222 22222; for an electrode sheet with 6 electrode units and 6 temperature detection units, the corresponding coding array is 11111 10222 22222 22222; for an electrode sheet with 7 electrode units and 7 temperature detection units, the corresponding coding array is 11111 11022 22222 22222; for an electrode sheet with 8 electrode units and 8 temperature detection units, the corresponding coding array is 11111 11102 22222222222; for an electrode sheet with 9 electrode units and 9 temperature detection units, the corresponding coding array is 11111 11110 22222 22222; for an electrode sheet with 10 electrode units and 10 temperature detection units, the corresponding coding array is 11111 11111 02222 22222; for an electrode sheet with 11 electrode units and 11 temperature detection units, the corresponding coding array is 11111 11111 10222 22222; for an electrode sheet with 12 electrode units and 12 temperature detection units, the corresponding coding array is 11111 111111102222222; for an electrode sheet with 13 electrode units and 13 temperature detection units, the corresponding coding array is 11111111111 11102 22222; for an electrode sheet with 14 electrode units and 14 temperature detection units, the corresponding coding array is 11111 11111 11110 22222; for an electrode sheet with 15 electrode units and 15 temperature detection units, the corresponding coding array is 11111 11111 11111 02222; for an electrode sheet with 16 electrode units and 16 temperature detection units, the corresponding coding array is 11111 11111 1111110222; for an electrode sheet having 17 electrode units and 17 temperature detection units, the corresponding coding array is 11111 11111 11111 11022; for an electrode sheet having 18 electrode units and 18 temperature detection units, the corresponding coding array is 11111 11111 11111 11102;The electrode sheet with 19 electrode units and 19 temperature detection units has a corresponding coding array of 11111 11111 11111 11110; the electrode sheet with 20 electrode units and 20 temperature detection units has a corresponding coding array of 11111 11111 11111111111; when the adapter is not connected to the electrode sheet, the corresponding coding array is 22222 22222 22222 22222. The coding array includes at least one of the first coding, the second coding and the third coding. ;
[0087] The above 21 number arrays are all different, so the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can determine the type of electrode sheet 110 connected to the adapter 120 or whether the electrode sheet 110 is connected through the coding array when the electrode sheet 110 is normal.
[0088] When the type of the electrode sheet 110 is determined, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 also determines whether the corresponding electrode sheet 110 has a temperature detection failure based on the coding array, wherein the analog temperature signal detected by each temperature detection unit 113 is also used to characterize whether the electrode sheet 110 has a temperature detection failure.
[0089] like Figure 2 As shown, in an electrode sheet 110 having 20 electrode units 112 and 20 temperature detection units 113, in the corresponding electrode sheet 110, assuming that the temperature sensor 114 numbered 20 is damaged (open circuit), the AD sampling value obtained by sampling the ADC unit 122 is 3.3V, the corresponding sampling code is 2, and the corresponding abnormal coding array is 11111 11111 11111 11112, which is inconsistent with the normal coding array 11111111111 11111 11111, so the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can distinguish the temperature detection failure.
[0090] In summary, when the temperature sensors 114 of the electrode sheet 110 are normal, the code "0" in the corresponding 20-bit code array is not the last bit, and the codes before the code "0" are all "1", and the codes after the code "0" are all "2"; or, the code "0" is the last bit and the codes before the code "0" are all "1"; or, all codes in the 20-bit code array are "1". When the temperature sensor 114 of the electrode sheet 110 is damaged, regardless of whether the code "0" in the corresponding 20-bit code array is the last bit, the code before the code "0" is a code different from "1" (code "2"), or all codes in the 20-bit code array are "1" or "2".
[0091] It should be noted that in the embodiment of the present application, the control switch 124 electrically connected to the multi-channel grounding wires 118 of the electrode sheet 110 and the bidirectional switch 125 electrically connected to the multi-channel dual-purpose signal wires 119 of the electrode sheet 110 are both provided in the adapter 120, but in other embodiments, the control switch 124 electrically connected to the grounding wire 118 and the bidirectional switch 125 electrically connected to the dual-purpose signal wire 119 can also be provided on the electrode sheet 110 or provided in the electric field generator 130, which will not be described in detail here. In addition, the ADC unit 122 provided in the adapter 120 can also be provided in the electric field generator 130 and directly controlled by the second controller 131.

Figure 1-Figure 4 The difference between the tumor electric field treatment system 100 shown is that, in terms of spatial structure, the multiple electrode units 212 of the electrode sheet 210 of this embodiment are connected in a symmetrical manner.

Therefore, only three of the four control switches 824 are connected to the ground line 818, and the other control switch 824 is suspended. Only three of the five bidirectional switching switches 825 are connected to the dual-purpose signal line 819, and the other two bidirectional switching switches 825 are suspended.

[0103] The flexible circuit board of the electrode sheet of the present application electrically connects the signal end of the same electrode unit and the temperature detection unit corresponding thereto through the same dual-purpose signal line. While it can transmit both the alternating electrical signal and the direct current signal for temperature signal collection and the collected temperature detection signal through the dual-purpose signal line, it also greatly reduces the number of conductive traces (grounding wire, dual-purpose signal line) arranged thereon, reduces the wiring difficulty of the flexible circuit board, simplifies the manufacturing process, reduces the weight of the flexible circuit board, and reduces the manufacturing cost; at the same time, it can realize real-time and comprehensive monitoring of the temperature of all electrode units on the electrode sheet without increasing the weight of the electrode sheet and the core of the first cable electrically connected to the electrode sheet, and then, if the electrode sheet is qualified, the type of the electrode sheet can be identified according to the obtained temperature detection signal, so that the type of the electrode sheet can be automatically identified, and then the temperature collection of different types of electrode sheets can be realized without missing the collection or generating interference signals; when the type of the electrode sheet is determined, the analog temperature signal detected by each temperature detection unit sampled is also used to characterize whether the electrode sheet has a temperature detection failure, so that an abnormal temperature detection unit can be identified.

[0106] Specifically, refer to Figure 2 , control the switching unit so that the dual-purpose signal line 119 corresponding to at least one column group in the corresponding electrode sheet 110 is connected to the corresponding temperature sampling point; control the control switch 124 corresponding to each row group so as to sample the analog temperature signal of the corresponding electrode unit 112 based on the corresponding temperature sampling point to determine the temperature detection signal of each electrode unit 112 in each electrode sheet 110.
[0107] S120: Determine the coding array of the corresponding electrode sheet according to the temperature detection signal.
[0108] S130: Determine the type of the corresponding electrode sheet based on the coding array.
[0109] Specifically, when the electrode sheet 110 is qualified or there is no abnormality or failure in each temperature detection unit 113 of the electrode sheet 110, the coding array of the corresponding electrode sheet 110 is determined based on the temperature detection signal detected by the temperature detection unit 113 of each electrode unit 112 in the electrode sheet 110, and then the type of the corresponding electrode sheet 110 is determined based on the coding array.
