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, tumor treatment equipment, and an electrode quality detection method. Background Art
[0002] At present, the tumor electric field therapy system mainly includes an electric field generator, an adapter electrically connected to the electric field generator, and multiple pairs of electrodes electrically connected to the electric field generator through the adapter. The electric field generator transmits the alternating electric signal for tumor electric field therapy to each electrode through the adapter, and then applies an alternating electric field to the patient's tumor site through the electrode to perform tumor electric field therapy. Since the alternating electric field applied to the patient will accumulate heat at the corresponding position where the electrode is attached to the skin, in order to avoid low-temperature burns of the skin, a temperature sensor needs to be configured at each electrode unit to monitor the skin surface temperature at each electrode unit. However, in the process of using electrode sheets for tumor treatment, it is inevitable that there will be an abnormal problem in which individual temperature sensors on a very small number of electrode sheets fail after a period of use. If the number of temperature sensors on the electrode sheets fails is too large, it is easy to cause the risk of low-temperature burns to the patient. Summary of the Invention
[0003] The present application aims to solve at least one of the technical problems in the related art to a certain extent. To this end, the first purpose of the present application is to propose a tumor electric field therapy system, which uses fewer conductive traces to control the partitioning of multiple electrode units and sample temperature detection signals, which can not only improve the effect of tumor electric field therapy, but also facilitate the application of electrode sheets. In addition, during the use of the electrode sheet, the sampled temperature detection signal can be used to monitor whether the electrode sheet is damaged, so that the electrode sheet can be replaced in time to avoid or reduce the risk of low-temperature burns for patients; during the production process of the electrode sheet, the sampled temperature detection signal can be used to monitor whether each temperature detection unit of the electrode sheet is connected normally, and then determine whether the electrode sheet is qualified, so as to screen out unqualified electrode sheets, thereby ensuring that each temperature detection unit of the electrode sheet leaving the factory can be detected normally.
[0004] The second purpose of this application is to provide a tumor treatment device.

At the same time, the switching unit is configured to switch the dual-purpose signal line to connect to the temperature sampling point or the alternating power line, so that when the dual-purpose signal line is connected to the temperature sampling point, the switching state of the control switch is configured so that the analog temperature signal detected by the corresponding temperature detection unit in each row group is sampled based on the temperature sampling point, and when the dual-purpose signal line is connected to the alternating power line, the electrode units of at least one column group are applied with an alternating electric signal based on the alternating power line. In this way, the temperature sampling and the application of the alternating electric signal can be realized through the dual-purpose signal line, which not only No new AC signal line (i.e., AC line) is added, and the original AC signal line is eliminated, so that multiple electrode units can be partitioned and controlled using fewer conductive traces, which not only improves the effect of tumor electric field therapy, but also facilitates the application of the electrode sheet; in addition, during the use of the electrode sheet, the test code array of the electrode sheet is determined based on the sampled temperature detection signal, and by comparing the test code array with the standard code array for consistency, it is possible to monitor whether the electrode sheet is damaged, so that the electrode sheet can be replaced in time to avoid or reduce the risk of low-temperature burns for patients; in the production process of the electrode sheet, the test code array of the electrode sheet is determined based on the sampled temperature detection signal, and by comparing the test code array with the standard code array for consistency, it is possible to monitor whether each temperature detection unit of the electrode sheet is normally connected, and then determine whether the electrode sheet is qualified, so as to screen out unqualified electrode sheets, thereby ensuring that each temperature detection unit of the electrode sheet leaving the factory can be detected normally.

DETAILED DESCRIPTION
[0034] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.
[0035] Some examples:
[0036] Figure 1 FIG. 1 is a schematic diagram of a tumor electric field treatment system 100 according to a first embodiment of the present application. Figure 1As shown, the tumor electric field treatment system 100 includes: at least one pair of electrode sheets 110, an adapter 120 connected to the at least one pair of electrode sheets 110, and an electric field generator 130 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 alternating electric signal generated by the electric field generator 130 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 the alternating electric field to the tumor site of the patient for tumor treatment.
[0037] like Figure 1 As shown, in this embodiment, there are four electrode sheets 110, each of which 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 therapy system 100 may have more or fewer electrode sheets 110; in other embodiments, each pair of electrode sheets 110 has the same number of electrode units 112, while 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.
[0038] Figure 2 for Figure 1 The diagram shows the circuit connection between an electrode 110 and an adapter 120 of the tumor electric field treatment system 100. It is worth noting that: Figure 2 The arrangement of the electrode units 112 is shown to more clearly illustrate the electrical connection between an electrode sheet 110 and the adapter 120. Figure 2 The arrangement of the electrode units 112 shown does not represent the arrangement of the electrode units 112 in the spatial structure. 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 is embedded with a plurality of conductive traces, which include a plurality of grounding wires 118 and a plurality of dual-purpose signal wires 119. The first cable 116 has nine core conductors (not shown), each of which is electrically connected one-to-one with the plurality of grounding wires 118 and the plurality of dual-purpose signal wires 119 of the substrate 111. In this embodiment, the total number of grounding wires 118 and dual-purpose signal wires 119 embedded in the substrate 111 does not exceed 9, and thus the number of conductors of the first cable 116 does not exceed 9.
[0039] The multiple electrode units 112 are arranged into multiple row groups and multiple column groups. In this embodiment, each electrode sheet 110 is provided with 20 electrode units 112. The 20 electrode units 112 are arranged in the order of 1 to 20 for circuit connection, 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 for 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 temperature detection units 113 are both soldered to the substrate 111, and the electrode units 112 are short-circuited with the signal terminals 113B of the corresponding temperature detection units 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 row groups and five column groups for circuit connection. It should be noted that the arrangement here is to more clearly illustrate 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. The spatial structure may be as follows: Figure 1The generally array-like structure shown can also be other structures, such as petal-shaped or scattered, and can be regular or irregular. The electrode units 112 are configured to apply alternating electrical signals to the patient's tumor site. The temperature detection unit 113 is configured to detect the temperature of the patient's body surface to which the electrode sheet 110 is applied, i.e., the temperature at the corresponding electrode unit 112, and output the temperature detection signal to an external device, such as an adapter 120. In this embodiment, the multiplexed signal lines 119 of the substrate 111 are provided in a one-to-one correspondence with the multiple column groups of electrode units 112, and are configured to transmit the alternating electrical signal generated by the electric field generator 130 to each electrode unit 112 in the corresponding column group. That is, the electrode units 112 in the same column group are short-circuited by the same dual-purpose signal line 119 of the substrate 111, while the electrode units 112 in different column groups are connected in parallel by different dual-purpose signal lines 119 of the substrate 111. The dual-purpose signal line 119 of the substrate 111 is electrically connected to the first cable 116 and then electrically connected to the electric field generator 130 via the adapter 120. Furthermore, the dual-purpose signal line 119 of the substrate 111 receives the alternating electric signal generated by the electric field generator 130 through the first cable 116 and the adapter 120.
[0040] Multiple grounding lines 118 are provided in a one-to-one correspondence with the multiple row groups of electrode units 112. Multiple grounding lines 118 are used to sequentially short-circuit each temperature detection unit 113 in each row group to ground. Specifically, the grounding terminals 113A of the temperature detection units 113 in the same row group are all short-circuited via the same grounding line 118 on the substrate 111. The grounding terminals 113A of the temperature detection units 113 in different row groups are connected in parallel via different grounding lines 118 on the substrate 111. During the temperature detection period, only one of the multiple grounding lines 118 is conductive at any given time; the remaining grounding lines 118 are disconnected.
[0041] Each of the multiplexed dual-purpose signal lines 119 is further configured to short-circuit the signal terminal 113B of at most one temperature detection unit 113 in each row group to an external device for receiving a detection signal. Each of the multiplexed dual-purpose signal lines 119 is connected to a different signal terminal 113B of each temperature detection unit 113 to prevent the dual-purpose signal lines 119 from subsequently outputting duplicate signals. 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 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, at least one dual-purpose signal line 119 is not electrically connected to the signal terminal 113B of a temperature detection unit 113, and each of the remaining dual-purpose signal lines 119 is electrically connected to the signal terminal 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 terminals 113B of the temperature detection units 113 in different column groups are connected in parallel via different dual-purpose signal lines 119 on the substrate 111. The signal terminals 113B of the temperature detection units 113 in the same column group are all short-circuited to the same dual-purpose signal line 119 on the substrate 111.
[0042] 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 conductors in the first cable 116, thereby preventing the cable from becoming thicker and the cable from becoming harder, which increases the difficulty of cable fixation. At the same time, the increase in the number of conductors in the first cable 116 prevents the adhesion effect between the electrode sheet 110 and the patient's body surface corresponding to the tumor site. The grounding wires 118 and dual-purpose signal wires 119 embedded in the substrate 111 total 9 lines. Specifically, in this embodiment, the grounding wires 118 embedded in the substrate 111 are 4 lines, and the dual-purpose signal wires 119 are 5 lines. The number of grounding wires 118 is related to the number M of row groups of the electrode units 112, which is greater than or equal to the number of row groups of the electrode units 112, and M is a positive integer. The number of dual-purpose signal wires 119 is related to the number N of column groups of the electrode units 112, which is greater than or equal to the number of column groups of the electrode units 112, and 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 M of row groups of electrode units 112; the number of dual-purpose signal lines 119 is equal to the number N of column groups of electrode units 112.
[0043] In terms of spatial structure, a plurality of electrode units 112 are arranged on the substrate 111 in a roughly two-dimensional array. 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. 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 respectively 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 respectively located in each of the first to sixth columns.
[0044] like Figure 1As shown, in terms of spatial structure, multiple electrode units 112 are connected in an asymmetric manner. For example, any two 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 (unnumbered). At the same time, any two 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 (unnumbered). Each electrode sheet 110 has a free end. For example, there is at least one electrode unit 112 in the plurality of electrode units 112 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 second row and second column, the third row and first column, the third row and second column, and the fourth row and second column have no connection strips in the column direction, thereby forming an open space, and the open space is adjustable. For example, the position of the electrode unit 112 in the first row and second column is movable compared to the position of the electrode unit 112 in the first row and third column, the position of the electrode unit 112 in the second row and first column is movable compared to the position of the electrode unit 112 in the second row and second column, and the position of the electrode unit 112 in the third row and second column is movable compared to the position of the electrode unit 112 in the third row and second column. The electrode units 112 in the first column of the row are movable compared to the electrode units 112 in the second column of the third row, and the electrode units 112 in the second column of the fourth row are movable compared to the electrode units 112 in the third column of the fourth row. Therefore, when the electrode sheet 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 second column of the first row, the first column of the second row, the first column of the third row, and the second column of the fourth row. This can increase the heat dissipation space of the corresponding electrode units 112, thereby accelerating heat dissipation, and at the same time helping the patient adjust the position of the electrode unit 112 based on the fever situation or the skin condition of the area where the electrode sheet 110 is applied.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 sixth column, and the fourth row and fourth column are not connected by connecting strips in the column direction, thereby forming an open space, and the open space 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 first row and fifth column, the position of the electrode unit 112 in the second row and fourth column and the second row and sixth column is movable compared to the electrode unit 112 in the second row and fifth column, and the position of the electrode unit 112 in the third row and sixth column is movable compared to the electrode unit 112 in the third row and fifth column. The electrode units 112 in the fourth row and fourth column are movable compared to the electrode units 112 in the fourth row and fifth column. Therefore, when the electrode sheet 110 is applied to the patient's body surface, by adjusting the positions of the electrode units 112 in the first row and fourth column, the second row and fourth column, the third row and sixth column, and the fourth row and fourth column, the open space between the corresponding electrode units 112 can be adjusted. This can increase the heat dissipation space of the corresponding electrode units 112, thereby accelerating the heat dissipation and helping the patient to adjust the position of the electrode unit 112 based on the fever situation or the skin condition of the area where the electrode sheet 110 is applied.
[0045] 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 second row and first column, the third row and first column, the fourth row and second column, and the fourth row and third column can be divided into region 2, the four electrode units 112 located in the second row and sixth column, the third row and sixth column, the fourth row and fourth column, and the fourth row and fifth column can be divided into region 3, the four electrode units 112 located in the second row and second column, the second row and third column, the third row and second column, and the third row and third column can be divided into region 4, and the four electrode units 112 located in the second row and fourth column, the second row and fifth column, the third row and fourth column, and the third row and fifth column can be divided into region 5. The electrode units 112 in each region (1-5) are divided into region 1-5. Figure 2 The circuit connections shown correspond to a column group, and the corresponding 20 electrode units 112 are arranged in four rows and five columns in the circuit connection. 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 the present application is not limited by the number and arrangement of the electrode units 112 of the electrode sheet 110.
[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, or a polymer dielectric layer composed of a polymer material. Each temperature detection unit 113 is provided corresponding to an electrode unit 112 to detect the temperature at the corresponding electrode unit 112. Each temperature detection unit 113 can be provided at any position of the corresponding electrode unit 112. In this embodiment, each electrode unit 112 is provided with a through-hole 1121, and the through-hole 1121 is suitable for installing the temperature detection unit 113. For example, the middle part of each electrode unit 112 has a through-hole 1121, and the through-hole 1121 of each electrode unit 112 accommodates a corresponding temperature detection unit 113. 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 sensor other than a thermistor. 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. The diode 115 can prevent reverse current flow 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 four grounding wires 118, each of which is used to ground the ground terminals 113A of the temperature detection units 113 in the same row group. The four grounding wires 118 of the electrode sheet 110 are 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. Among the four 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, first grounding line 118-1 is used to ground electrode units 112-1 to 112-5 in the first row group; second grounding line 118-2 is used to ground electrode units 112-6 to 112-10 in the second row group; third grounding line 118-3 is used to ground electrode units 112-11 to 112-15 in the third row group; and fourth grounding line 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 lines 118 can be selectively closed or opened. This can be achieved by connecting each grounding line 118 in series with a control switch 124. That is, the ground terminals 113A of the temperature detection units 113 corresponding to the electrode units 112 in each row group are connected to the ground pin through a control switch 124. This will be described in detail below. The aforementioned "grounding electrode units 112" may refer to grounding the ground terminal 114A of the temperature sensor 114 corresponding to each electrode unit 112, or it may refer to connecting the diode 115 in series with the temperature sensor 114 corresponding to the same electrode unit 112, thereby grounding both. In short, each grounding wire 118 short-circuits the ground terminals 113A of the temperature detection units 113 corresponding to all electrode units 112 in each row group, thereby grounding them.
[0048] like Figure 2As shown, the electrode sheet 110 of this embodiment also includes five dual-purpose signal lines 119. One end of each dual-purpose signal line 119 is connected to all electrode units 112 in each column group, and the other end is connected to an adapter 120 for receiving temperature detection signals and transmitting alternating electrical signals. In other words, for each row group, each dual-purpose signal line 119 can choose to connect to one of the electrode units 112 or not connect to any electrode unit 112 in the row group to avoid the dual-purpose signal line 119 from subsequently outputting duplicate signals. 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 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 temperature detection unit 113 corresponding thereto; 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 temperature detection unit 113 corresponding thereto; one end of the third dual-purpose signal line 119-3 is connected to the four electrode units 112, namely, electrode unit 112-3, electrode unit 112-8, and electrode unit 112-17, and the signal end 113B of the temperature detection unit 113 corresponding thereto; One end of a fourth dual-purpose signal line 119-4 is connected to the four electrode units 112, namely, electrode units 112-11, 112-13, 112-18, and the signal terminals 113B of their corresponding temperature detection units 113. One end of a fourth dual-purpose signal line 119-4 is connected to the four electrode units 112, namely, electrode units 112-4, 112-9, 112-14, and 112-19, and the signal terminals 113B of their corresponding temperature detection units 113. One end of a fifth dual-purpose signal line 119-5 is connected to the four electrode units 112, namely, electrode units 112-5, 112-10, 112-15, and 112-20, and the signal terminals 113B of their corresponding temperature detection units 113. In short, each dual-purpose signal line 119 parallel-circuits the electrode units 112 and the signal terminals 113B of their corresponding temperature detection units 113 in the same column group as temperature sampling points (not numbered) 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 switch 125 and coordinating the closing or opening of the ground line 118.That is, after the signal terminals 113B of the temperature detection units 113 in each column group are short-circuited with the corresponding electrode units 112, they are connected to a switching unit (not labeled) through a dual-purpose signal line 119. The switching unit (not labeled) includes a plurality of bidirectional switches 125, which are configured to switch the dual-purpose signal line 119 to connect to the temperature sampling point (not labeled) or the alternating power line 127. When the dual-purpose signal line 119 is connected to the temperature sampling point (not labeled), the switching state of the control switch 124 is configured to make the temperature detection signal detected by the corresponding temperature detection unit 113 in each row group Based on the temperature sampling point (unnumbered) being sampled, and when the dual-purpose signal line 119 is connected to the alternating power line 127, an alternating electrical signal is applied to the electrode units 112 of at least one column group based on the alternating power line 127, wherein the analog temperature signal detected by each sampled temperature detection unit 113 is used to determine the test coding array of the corresponding electrode sheet 110, and by comparing the test coding array with the standard coding array for consistency, the fault condition of each temperature detection unit 113 in the corresponding electrode sheet 110 is identified, or it is determined whether the corresponding electrode sheet 110 is qualified, which will be described in detail below.
[0049] The multiple ground lines 118 and the multiplexed signal lines 119 are conductive traces embedded in the substrate 111. The substrate 111 is electrically connected to the first cable 116. The multiple ground lines 118 and the multiplexed signal lines 119 embedded in the substrate 111 are electrically connected to corresponding wires (not shown) in the first cable 116.
[0050] The tumor electric field therapy system 100 of this embodiment includes at least one pair of electrode sheets 110 as described above, 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 alternating electrical signals to the multiple 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 receives temperature detection signals output by the temperature detection units 113 corresponding to the multiple 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 sheet 110, and is also configured to receive the temperature detection signals output by the multiplexed dual-purpose signal line 119 of the electrode sheet 110.
[0051] 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 sets of voltage transformers 123 and control switches 124 corresponding to the multiple ADC units 122, multiple sets of bidirectional switches 125 connected to the multiple ADC units 122, a first communication unit 126, an alternating current power line 127 connected to each set of bidirectional 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 a DC power supply VCC to the electronic components of the adapter 120. The adapter 120 also includes multiple circuit lines (unnumbered), which are electrically connected to multiple ground lines 118 and multiplexed signal lines 119 in the substrate 111 of the corresponding 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 substrate 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 substrate 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 substrate 111 of the corresponding electrode sheet 110. The number L of circuit lines electrically connected between the adapter 120 and one electrode sheet 110 is greater than or equal to the sum of the number of rows and columns of the electrode units 112 of the electrode sheet 110; the number H of circuits electrically connected between the adapter 120 and X electrode sheets 110 is greater than or equal to X times the number of circuit lines electrically connected between the adapter 120 and a single electrode sheet 110, that is, H=XL≥X*(M+N). In this embodiment, the number L of circuit lines electrically connected between the adapter 120 and one electrode sheet 110 is equal to the sum of the number of rows and columns of the electrode units 112 of the electrode sheet 110; the number H of circuits electrically connected between the adapter 120 and X electrode sheets 110 is equal to X times the number of circuit lines electrically connected between the adapter 120 and a single electrode sheet 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 sheets 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 control switches 124 and bidirectional switches 125 is the same as the number of electrode sheets 110. The electrical connection between an electrode sheet 110 having 20 electrode units 112 and the adapter 120 is described in detail below.
[0052] Each group of control switches 124 is provided with a plurality of control switches 124, and the plurality of control switches 124 are respectively connected to the adapter 120 and are respectively electrically connected to the circuit lines (not numbered) corresponding to the multi-way grounding lines 118 of the corresponding electrode sheet 110, and are configured to control the conduction or disconnection of the multi-way grounding lines 118. The circuit lines (not numbered) that are electrically connected to the multi-way grounding lines 118 of the electrode sheet 110 are grounded GND at one end close 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 of the substrate 111 of the corresponding electrode sheet 110, and the two are equal in this embodiment. Figure 2 As shown, in this embodiment, the multiple control switches 124 in each group of control switches 124 are respectively a first control switch 124-1, a second control switch 124-2, a third control switch 124-3, and a fourth control switch 124-4. The multiple control switches 124 in the same group each control the closing or opening of the corresponding ground line 118 of the same electrode sheet 110. Specifically, the first control switch 124-1 is used to control the closing or disconnection of the first grounding line 118-1 of the corresponding electrode sheet 110, and can then cooperate with the corresponding group of two-way switching switches 125 to control the power on and off of each temperature detection unit 113 corresponding to the five electrode units 112 from electrode unit 112-1 to electrode unit 112-5 in the first row group of the electrode sheet 110; the second control switch 124-2 is used to control the closing or disconnection of the second grounding line 118-2 of the electrode sheet 110, and can then cooperate with the corresponding group of two-way switching switches 125 to control the power on and off 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 group of the electrode sheet 110. The third control switch 124-3 is used to control the closing or disconnection of the third grounding line 118-3 of the electrode sheet 110, and can then cooperate with the corresponding group of two-way switching switches 125 to control the power on and off of each temperature detection unit 113 corresponding to the five electrode units 112 from electrode unit 112-11 to electrode unit 112-15 in the third row group of the electrode sheet 110; the fourth control switch 124-4 is used to control the closing or disconnection of the fourth grounding line 118-4 of the electrode sheet 110, and can then cooperate with the corresponding group of two-way switching switches 125 to control the power on and off of each temperature detection unit 113 corresponding to the five electrode units 112 from electrode unit 112-16 to electrode unit 112-20 in the fourth row group of the electrode sheet 110. The above-mentioned control switch 124 can be a mechanical switch, such as a relay. The control switch 124 can also be an electronic switch, and each control switch 124 can be opened and closed by an additional first controller 121.
[0053] In this embodiment, the multiple groups of control switches 124 are all electronic switches. The first controller 121 is in communication with the multiple groups of control switches 124 and is used to sequentially and cyclically control the on and off states of the multiple control switches 124 in each group of control switches 124, thereby sequentially and individually conducting each of the multiple grounding wires 118 of the corresponding electrode sheet 110 and coordinating the switching of the corresponding bidirectional switch 125 to collect the temperature of the patient's body surface detected by all temperature detection units 113 on the electrode sheet 110. The number of each group of control switches 124 is not less than the number of grounding wires 118 of the substrate 111 of the corresponding electrode sheet 110. In this embodiment, the number of each group of control switches 124 is the same as the number of grounding wires 118 of the corresponding electrode sheet 110.
[0054] Each set of bidirectional switches 125 includes a plurality of bidirectional switches 125. The plurality of bidirectional switches 125 in each set are connected to the adapter 120 and are electrically connected to circuit lines (not numbered) that correspond one-to-one with the multiplexed signal lines 119 of a corresponding electrode sheet 110. The number of bidirectional switches 125 in each set of bidirectional switches 125 is related to the number of dual-purpose signal lines 119 of the substrate 111 of the corresponding electrode sheet 110, and is greater than or equal to the number of dual-purpose signal lines 119 of the substrate 111 of the corresponding electrode sheet 110. In this embodiment, the number of bidirectional switches 125 is equal to the number of dual-purpose signal lines 119 of the substrate 111 of the corresponding electrode sheet 110. Each bidirectional switch 125 has two ends labeled 1 and 2. One end of multiple bidirectional switches 125 in the same group is electrically connected one by one to corresponding detection channels of multiple detection channels of a corresponding group of ADC units 122 through temperature sampling points (unnumbered). Both ends of each bidirectional switch 125 in the same group are electrically connected to the same corresponding alternating power line 127, and are configured to control the multiplexed signal line 119 to connect to the corresponding alternating power line 127 to transmit alternating 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.
[0055] like Figure 2As shown, taking the electrical connection between one electrode sheet 110 and the adapter 120 as an example, in this embodiment having 20 electrode units 112, the multiple bidirectional switches 125 in each group of bidirectional switches 125 are respectively a first bidirectional switch 125-1, a second bidirectional switch 125-2, a third bidirectional switch 125-3, a fourth bidirectional switch 125-4, and a fifth bidirectional switch 125-5. The multiple bidirectional switches 125 in the same group each control the switching between transmitting an alternating electrical signal and transmitting a temperature detection signal on a corresponding one of the multiplexed signal lines 119 of the same electrode sheet 110. Specifically, the first bidirectional 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 the alternating electric signal and transmitting the temperature detection signal, thereby controlling the conduction of each electrode unit 112 of the electrode unit 112-1, the electrode unit 112-6, the electrode unit 112-11, and the electrode unit 112-16 in the first column group of the electrode sheet 110 and the conduction of the electrode unit 112-1, the electrode unit 112-6, the electrode unit 112-11, and the electrode unit 112-16 in the first column group. The switching between the conduction of the signal terminals 113B of the temperature detection units 113 corresponding to 2-16 and the corresponding control switches 124-1, 124-2, 124-3, and 124-4 is coordinated to enable the first column of electrode units 112-1, 112-6, 112-11, and 112-16 to transmit alternating electrical signals to the patient or output the temperature detection signals collected by the temperature detection units 113 corresponding to the electrode units 112 to the corresponding ADC units 122. The second bidirectional switch 125-2 is used to control the switching of the second dual-purpose signal line 119-2 of the corresponding electrode sheet 110 between transmitting the alternating electric signal and transmitting the temperature detection signal, thereby controlling the conduction of each electrode unit 112 of the electrode unit 112-2, the electrode unit 112-7, the electrode unit 112-12, and the electrode unit 112-17 in the second column group of the electrode sheet 110 and the conduction of the electrode unit 112-2, the electrode unit 112-7, the electrode unit 112-12, and the electrode unit 112 in the second column group. The signal terminals 113B of the temperature detection units 113 corresponding to the second column 112-17 are switched on and cooperate with the corresponding control switches 124-1, 124-2, 124-3, and 124-4, so that the second column 112-2, 112-7, 112-12, and 112-17 transmit alternating electrical signals to the patient or output the temperature detection signals collected by the temperature detection units 113 corresponding to the electrode units 112 to the corresponding ADC units 122;The third bidirectional switch 125-3 is used to control the switching of the third dual-purpose signal line 119-3 of the corresponding electrode sheet 110 between transmitting the alternating electric signal and transmitting the temperature detection signal, thereby controlling the conduction of each electrode unit 112 of the electrode unit 112-3, the electrode unit 112-8, the electrode unit 112-13, and the electrode unit 112-18 in the third column group of the electrode sheet 110 and the conduction of the electrode unit 112-3, the electrode unit 112-8, the electrode unit 112-13, and the electrode unit 112-18 in the third column group. The signal ends 113B of the temperature detection units corresponding to the electrode units 112 are connected to each other and cooperate with the corresponding control switches 124-1, 124-2, 124-3 and 124-4, so that the third column of electrode units 112-3, 112-8, 112-13 and 112-18 transmit alternating electrical signals to the patient or output the temperature detection signals collected by the temperature detection units 113 corresponding to the electrode units 112 to the corresponding ADC unit 122; The four bidirectional switches 125-4 are used to control the switching of the fourth dual-purpose signal line 119-4 of the corresponding electrode sheet 110 between transmitting the alternating electric signal and transmitting the temperature detection signal, thereby controlling the conduction of each electrode unit 112 of the electrode unit 112-4, the electrode unit 112-9, the electrode unit 112-14, and the electrode unit 112-19 in the fourth column group of the electrode sheet 110 and the conduction of the electrode unit 112-4, the electrode unit 112-9, the electrode unit 112-14, and the electrode unit 112-19 in the fourth column group. The signal terminals 113B of the temperature detection units 113 corresponding to the fourth column 112-4, 112-9, 112-14, and 112-19 are connected to the corresponding control switches 124-1, 124-2, 124-3, and 124-4, so that the fourth column 112-4, 112-9, 112-14, and 112-19 transmit alternating electrical signals to the patient or output the temperature detection signals collected by the temperature detection units 113 corresponding to the electrode units 112 to the ADC unit 122.The fifth bidirectional switch 125-5 is used to control the switching of the fifth dual-purpose signal line 119-5 of the corresponding electrode sheet 110 between transmitting the alternating electric signal and transmitting the temperature detection signal, thereby controlling the conduction of each electrode unit 112 of the electrode unit 112-5, the electrode unit 112-10, the electrode unit 112-15, and the electrode unit 112-20 in the fifth column group of the electrode sheet 110 and the conduction of the electrode unit 112-5, the electrode unit 112-10, the electrode unit 112-15, and the electrode unit 112-20 in the fifth column group. The signal terminals 113B of the temperature detection units 113 corresponding to the electrode sheets 110 are switched on and off, and cooperate with the corresponding control switches 124-1, 124-2, 124-3, and 124-4 to cause 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 the temperature detection signals collected by the temperature detection units 113 corresponding to these electrode units 112 to the corresponding ADC units 122. When the two terminals of each set of bidirectional switches 125 are on and one terminal is off, the alternating electrical signals can be transmitted to the respective electrode units 112 of the corresponding electrode sheet 110. When the one terminal of each set of bidirectional switches 125 is on and the two terminals are off, the bidirectional switches 125 can cooperate with the respective control switches 124 in the corresponding set of control switches 124 to sequentially and time-share the temperature detection signals collected by the temperature detection units 113 of the respective electrode units 112 on the electrode sheet 110. The bidirectional switch 125 may be a mechanical switch, such as a relay. The bidirectional switch 125 may also be an electronic switch, and each bidirectional switch 125 may be switched by an additional first controller 121.
[0056] In this embodiment, the plurality of sets of bidirectional switches 125 are all electronic switches. The first controller 121 is in communication with the plurality of sets of bidirectional switches 125 and is configured to control the plurality of bidirectional switches 125 in each set of bidirectional switches 125 to switch between their respective terminals 1 and 2, and to coordinate the closing or opening of the corresponding control switch 124 to continuously monitor the patient's body surface temperature detected by all temperature detection units 113 on the electrode sheet 110 or to transmit an alternating electrical signal to the patient.
[0057] In this embodiment, each group of ADC units 122 is electrically connected to one end of each of the multiple bidirectional switches 125 in the corresponding group of bidirectional switches 125 through a multi-channel circuit line (not numbered) in the adapter 120, and is configured to receive the temperature detection signal transmitted by the multiplexed signal line 119 of the corresponding electrode sheet 110, and convert the temperature detection signal from an analog signal to a digital signal. Each group of ADC units 122 includes a plurality of detection channels A, B, C, D, and E that are set in a one-to-one correspondence with the corresponding temperature detection points (not numbered). Each detection channel A, B, C, D, and E is used to connect to a corresponding one of the multiplexed signal lines 119 through the corresponding bidirectional switch 125. Figure 2 As shown, each ADC unit 122 includes a total of 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 one end of the first bidirectional switch 125-1, the second detection channel B is connected to the second dual-purpose signal line 119-2 via one end of the second bidirectional switch 125-2, the third detection channel C is connected to the third dual-purpose signal line 119-3 via one end of the third bidirectional switch 125-3, the fourth detection channel D is connected to the fourth dual-purpose signal line 119-4 via one end 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 one end 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, E is connected to a first power module 128 for providing a detection voltage to the detection channel A, B, C, D, E via a corresponding voltage divider resistor 123 in the adapter 120. The first power module 128 provides direct current.
[0058] In this embodiment, the first controller 121 is further configured to determine the test code array of the corresponding electrode sheet 110 based on the sampled analog temperature signal detected by each temperature detection unit 113, and compare the test code array with the standard code array for consistency to identify the fault condition of each temperature detection unit 113 in the corresponding electrode sheet 110. The standard code array is the code array when the electrode sheet 110 is qualified. The adapter 120 may also include a reminder unit (not shown). When there is a faulty temperature detection unit 113 in the electrode sheet 110, the first controller 121 controls the reminder unit (not shown) to issue a first reminder message and instruct the electric field generator 130 to continue working. For example, when there is no faulty temperature detection unit 113 in the electrode sheet 110, the first controller 121 controls the reminder unit (not shown) such as an indicator light to light green, and when there is a faulty temperature detection unit 113 in the electrode sheet 110, the reminder unit (not shown) is controlled such as an indicator light to light red.
[0059] In this embodiment, the first controller 121 is also configured to determine the number of faulty temperature detection units 113 in the electrode sheet 110 when the test coding array is compared with the standard coding array for consistency, and judge whether the electrode sheet 110 needs to be replaced based on the number. For example, when the number exceeds a preset number (the minimum can be set to 1), it is judged that the electrode sheet 110 needs to be replaced, and when the number does not exceed the preset number, it is judged that the electrode sheet 110 does not need to be replaced. The first controller 121 can also control the reminder unit (not shown) to issue a second reminder message and instruct the electric field generator 130 to stop working when it is judged that the electrode sheet 110 needs to be replaced. For example, when the first controller 121 judges that the electrode sheet 110 needs to be replaced, it controls the reminder unit (not shown) such as the indicator light to light red and flash, and can also control the reminder unit (not shown) such as the buzzer alarm.
[0060] In this embodiment, the first communication unit 126 is configured to obtain digital signals output by multiple sets of ADC units 122 and transmit the digital signals to the electric field generator 130. The electric field generator 130 is further configured to control and adjust the voltage of the alternating electrical signal provided to the multiple electrode units 112 of the electrode sheet 110 based on the received digital signals. For example, when any of the multiple digital signals received exceeds a preset threshold, it indicates that the temperature detected by the temperature detection unit 113 corresponding to at least one electrode unit 112 in the electrode sheet 110 exceeds a preset temperature threshold (e.g., 41°C, 42°C, etc.). In this case, the voltage of the alternating electrical signal output by the electric field generator 130 can be appropriately reduced to prevent the electrode units 112 of the electrode sheet 110 from overheating when the alternating electrical signal is applied, thereby preventing low-temperature burns on the patient's skin. The above-mentioned preset temperature threshold and preset threshold can be determined based on human safety thresholds. The first communication unit 126 is controlled by the first controller 121 and serially transmits the digital signals converted by the multiple sets of ADC units 122. In this embodiment, the preset temperature threshold can be a value within the range of 36°C-45°C. In this embodiment, the electric field generator 130 is also configured to determine the test coding array of the corresponding electrode sheet 110 based on the sampled analog temperature signal detected by each temperature detection unit 113, and compare the test coding array with the standard coding array for consistency to identify the fault condition of each temperature detection unit 113 in the corresponding electrode sheet 110.

Figure 1As shown, the adapter 120 also includes a second cable 129 connected to a second connector 150. The second connector 150 includes a second plug 151 located at the end of the second cable 129 away from the first controller 121 and a second socket 152 located on the electric field generator 130. The second plug 151 and the second socket 152 are push-type spring connectors, meaning that the second connector 150 connects the adapter 120 to the electric field generator 130 using a connector. Each first connector 140, such as X1, Y1, X2, and Y2, is connected to the second connector 150 via a corresponding alternating power line 127. The first connectors 140, such as X1, Y1, X2, and Y2, are also connected to a corresponding set of control switches 124 and a corresponding set of ADC units 122. Each first connector 140 is connected to the second connector 150 and a corresponding set of ADC units 122 via a corresponding set of bidirectional switches 125. The second cable 129 has eight conductors, including four conductors 1 to 4 electrically connected to corresponding AC power lines 127 for transmitting alternating electrical signals, one conductor 5 electrically connected to the data receiving line RX of the first communication unit 126, one conductor 6 electrically connected to the data transmitting line TX of the first communication unit 126, one conductor 7 electrically connected to the VCC power line of the first power module 128, and one conductor 8 electrically connected to the GND line of the first power module 128.

The VCC pin of the second connector 150 is also connected to the corresponding set of voltage dividers 123 and the corresponding set of ADC units 122 via the VCC power line of the first power module 128.
[0063] refer to Figure 4The electric field generator 130 includes a second power supply module 136, a second controller 131, an AC signal generator 132, a second communication unit 135, and a set of power switches 133. The VCC pin of the second connector 150 is also electrically connected to the VCC power line of the second power supply module 136, and the GND pin of the second connector 150 is grounded via the GND line of the second power supply module 136. The second power supply module 136 is also connected to the second controller 131 and the AC signal generator 132, respectively, and provides power to them. The second communication unit 135 is electrically connected to the wire 5 of the second connector 150 via its data receiving line RX and to the wire 6 of the second connector 150 via its data transmitting line TX, thereby enabling information exchange between the electric field generator 130 and the adapter 120.

The second controller 131 is configured to control the opening and closing of each of the power switches 133 in the set, and to adjust parameters of the alternating electrical signal applied by the AC signal generator 132, based on digital signals received from the adapter 120 by the second communication unit 135. The AC signal generator 132 is electrically connected to the conductors 1 to 4 of the second connector 150 that transmit the alternating electrical signal via the set of power switches 133. The set of power switches 133 includes a plurality of power switches 133, each corresponding to a plurality of electrode pads 110. Each power switch 133 is electrically connected to a corresponding conductor 1, 2, 3, or 4 in the second connector 150, which transmits an alternating electrical signal, via an AC power line 134-1, 134-2, 134-3, or 134-4. The conductors 1, 2, 3, or 4 of the second connector 150 are then electrically connected to the corresponding electrode pad 110, thereby transmitting an alternating electrical signal to each electrode pad 110. The AC signal generator 132 is electrically connected to the group of power switches 133 via multiple AC power lines 134. Specifically, the number of power switches 133 in the electric field generator 130 is related to the number of electrode pads 110. In this embodiment, the number of power switches 133 is equal to the number of electrode pads 110, and both are four.

[0064] In this embodiment, the second controller 131 is further configured to determine the test code array of the corresponding electrode sheet 110 based on the sampled analog temperature signal detected by each temperature detection unit 113, and compare the test code array with the standard code array for consistency to identify the fault condition of each temperature detection unit 113 in the corresponding electrode sheet 110. The electric field generator 130 may also include a reminder unit (not shown). When there is a faulty temperature detection unit 113 in the electrode sheet 110, the second controller 131 controls the reminder unit (not shown) to issue a first reminder message and continues to control the AC signal generator 132 to output an alternating electric signal.

The host computer (not shown) is also connected to an alarm, so as to control the alarm (not shown) to issue a reminder message when the electrode sheet 110 is unqualified.
[0067] 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.
[0068] 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 disconnected, 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 and 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 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, and E of each group of ADC units 122 only collects the temperature detection signals of the temperature detection units 113 corresponding to the electrode units 112 of the same row group of the electrode sheet 110 at the same time, and the above-mentioned temperature detection signals can be represented by voltage values. 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. All five bidirectional switches 125 in a group of bidirectional switches 125 corresponding to the group of ADC units 122 are 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, and E of the corresponding ADC unit 122 in a one-to-one correspondence and is turned on. With this arrangement, the group of ADC units 122 can collect the voltage values of all temperature detection units 113 corresponding to the electrode units 112 in the same row group that are short-circuited with the ground line 118 corresponding to the turned-on control switch 124.
[0069] 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 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 112-1 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 temperature detection units 113 corresponding to the electrode units 112-1, 112-6, 112-11, and 112-16 of the first detection channel A of the group of ADC units 122 are short-circuited. Since only the signal terminal 113B of the temperature detection unit 113 corresponding to electrode unit 112-1 is connected to the ground, while the ground terminals 113A of the temperature detection units 113 corresponding to electrode units 112-6, 112-11, and 112-16 are disconnected, and each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, the resistance of the temperature detection unit 113 corresponding to electrode unit 112-1 will not be affected. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-1 is effectively operating on the first detection channel A of the 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 by the second detection channel B in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-2. The voltage value collected on the third detection channel C in the set 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 set 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 set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-5.
[0070] When the control switch 124-2 is closed, the control switch 124-1, the control switch 124-3 and the control switch 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 112-6 to the electrode units 112-10 of the second row group are powered on, and the temperature detection units 113 corresponding to the electrode units 112-1 to the electrode units 112-5 and the electrode units 112-11 to the electrode units 112-20 of the remaining row groups are powered off, and the electrode units 112-1, the electrode units 112-6, the electrode units 112-11 and the electrode units 112-16 are short-circuited on the first detection channel A of the group of ADC units 122. Since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-6 is connected to ground, 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 signal terminals 113B of the corresponding temperature detection units 113 do not affect the resistance of the temperature detection unit 113 corresponding to electrode unit 112-6. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-6 is effectively operating on the first detection channel A of the set 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 by the second detection channel B of the set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-7. The voltage value collected on the third detection channel C in the set 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 set 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 set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-10.
[0071] When the control switch 124-3 is closed, the control switch 124-1, the control switch 124-2 and the control switch 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 the 1 end, the electrode units 112-11 to 112-15 of the third row group are powered on, the electrode units 112-1 to 112-10 and 112-16 to 112-20 of the other row groups are powered off, the signal end 113B of the temperature detection unit 113 corresponding to each of the short-circuited electrode units 112-1, 112-6, 112-11 and 112-16 on the first detection channel A of the ADC unit 122 is connected, only the ground end 113A of the temperature detection unit 113 corresponding to the electrode unit 112-11 is connected to the ground, the ground end 113A of each of the temperature detection units 113 corresponding to the electrode units 112-1, 112-6 and 112-16 is disconnected, each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, and the resistance value of the temperature detection unit 113 corresponding to the electrode unit 112-11 is not affected, so only the temperature detection unit 113 corresponding to the electrode unit 112-11 works effectively on the first detection channel A of the ADC unit 122, 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 112-11. Similarly, the voltage value collected by the second detection channel B of the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-12. The voltage value collected by the third detection channel C of the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-13. The voltage value collected by the fourth detection channel D of the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-14. The voltage value collected by the fifth detection channel E of the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-15.
[0072] When the control switch 124-4 is closed, the control switches 124-1, 124-2, and 124-3 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 112-16 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 temperature detection units 113 corresponding to the electrode units 112-1 to 112-15 of the remaining row groups are short-circuited on the first detection channel A of the ADC unit 122 of the group. 3, since only the ground terminal 113A of the temperature detection unit 113 corresponding to electrode unit 112-16 is connected to the ground, while the ground terminals 113A of the temperature detection units 113 corresponding to electrode units 112-1, 112-6, and 112-11 are all 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 112-16 will not be affected. Therefore, only the temperature detection unit 113 corresponding to electrode unit 112-16 is effectively operating on the first detection channel A of the group of ADC units 122. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-16. Similarly, the voltage value collected by the second detection channel B in the group of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to electrode unit 112-17. The voltage value collected on the third detection channel C in the set 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 set 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 set of ADC units 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-20.
[0073] Thus, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can collect the temperature detection signals of the temperature detection units 113 corresponding to all electrode units 112 of a certain electrode sheet 110 by controlling a set of bidirectional switching switches 125 and a set of control switches 124 that are electrically connected to the 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 switching state 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.
[0074] 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 according to 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 the dual-purpose signal lines 119 of the corresponding electrode sheet 110 are electrically connected to the corresponding group of ADC units 122. Then, the control switch 124-1 in the corresponding group of control switches 124 is closed, and the remaining control switches 124-2 to 124-4 in the group of control switches 124 are turned off. During this period, the ADC units 122 in the corresponding group of control switches 124 are turned off. Each detection channel A, B, C, D, and E of the ADC unit 122 obtains the temperature detection signals of each temperature detection unit 113 corresponding to each electrode unit 112 in the first row group of the corresponding electrode sheet 110, converts them into digital signals, and stores them in a separately provided memory. Then, after a preset interval, the first controller 121 or the second controller 131 closes the control switch 124-2 in the group of control switches 124 and opens the 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 obtains the temperature detection signals of each temperature detection unit 113 corresponding to each electrode unit 112 in the second row group. By sequentially turning on each control switch 124 in the group of control switches 124, the temperature detection signals of all temperature detection units 113 on the electrode sheet 110 can be obtained. Similarly, through this operation, the temperature detection signals of all temperature detection units 113 on at least one pair of electrode sheets 110 are obtained.
[0075] It should be noted that in other embodiments, the temperature detection signals of the temperature detection units 113 corresponding to the electrode units 112 of a column group can also be sampled in the same temperature sampling period by controlling the group of bidirectional switches 125 and the group of control switches 124 electrically connected to the electrode sheet 110 through the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130. For example, when only the first bidirectional switch 125-1 is switched to its 1 terminal, the control switch 124-1 can be controlled to be closed, and the control switch 124-2, the control switch 124-3, and the control switch 124-4 are all opened, at this time, only the temperature detection units 113 corresponding to the electrode units 112-1 of the first row group are powered on, 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 of the group of ADC units 122, and 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 control switch 124-2 is controlled to be closed, and the control switch 124-1, the control switch 124-3, and the control switch 124-4 are all opened, at this 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 control switch 124-3 is controlled to be closed, and the control switch 124-1, the control switch 124-2, and the control switch 124-4 are all opened, at this 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 control switch 124-4 is controlled to be closed, and the control switch 124-1, the control switch 124-2, and the control switch 124-3 are all opened, at this 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 sampling period, only the temperature detection signals of the temperature detection units 113 corresponding to the electrode units 112 of a column group can be sampled. Similarly, in other sampling 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 numbered) is configured to switch the two-purpose signal lines 119 corresponding to each column group to be connected to the corresponding temperature sampling points (not numbered) respectively, and the temperature detection signals detected by each temperature detection unit 113 in each column group are sampled by configuring the switch state of the control switch 124. It should be noted that in other embodiments, the temperature detection signals of the temperature detection units 113 corresponding to two column groups, three column groups, or four column groups of electrode units 112 can also be sampled in the same sampling period, which will not be described here in detail.
[0076] Specifically, when it is required 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 2 terminal of each of the plurality of bidirectional switching switches 125 of the group of bidirectional switching switches 125 electrically connected to the electrode sheet 110 to be conductive and the 1 terminal to be disconnected, controls all of the plurality of control switches 124 of the group of control switches 124 electrically connected to the electrode sheet 110 to be disconnected, and controls one of the power supply switches 133 electrically connected to the electrode sheet 110 to be conductive, at this time, the second controller 131 of the electric field generator 130 controls the alternating current signal generator 132 to apply an alternating electric signal to each electrode unit 112 of the electrode sheet 110 through the alternating power supply 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 two-purpose signal line 119 corresponding to at least two column groups to be connected to the alternating power supply line 127 at the same time, so that the electrode units 112 of the at least two column groups are simultaneously applied with the alternating electric signal based on the alternating power supply line 127.
[0077] It should be noted that in other embodiments, a group of bidirectional switching switches 125 electrically connected to a certain electrode sheet 110 can also be controlled by the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 to apply an alternating electric signal to part of the electrode units 112 of the electrode sheet 110 during 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 2 terminal of the first bidirectional switching switch 125-1 of the plurality of bidirectional switching switches 125 of the group of bidirectional switching switches 125 electrically connected to the electrode sheet 110 to be conductive and the 1 terminal to be disconnected, controls all of the plurality of control switches 124 of the group of control switches 124 electrically connected to the electrode sheet 110 to be disconnected, and controls one of the power supply switches 133 electrically connected to the electrode sheet 110 to be conductive, at this time, the second controller 131 of the electric field generator 130 controls the alternating current signal generator 132 to apply an alternating electric signal to the first column group electrode unit 112-1, the electrode unit 112-6, the electrode unit 112-11, and the electrode unit 112-16 of the electrode sheet 110 through the alternating power supply 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 two-purpose signal line 119 corresponding to each column group to be connected to the alternating power supply line 127, respectively, so that the electrode units 112 of each column group are simultaneously applied with the alternating electric signal based on the alternating power supply line 127. It should be noted that in other embodiments, two column groups, three column groups, or four column groups of electrode units 112 can also be simultaneously applied with an alternating electric signal during the same time period, which will not be described in detail here.
[0078] Specifically, during the use of the electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can determine the test code array of the electrode sheet 110 based on the sampled temperature detection signal detected by each temperature detection unit 113, and compare the test code array with the standard code array for consistency to monitor whether the electrode sheet 110 is damaged, so as to facilitate timely replacement of the electrode sheet 110 and avoid or reduce the risk of low-temperature burns in patients. For example, the temperature sensor 114 in the temperature detection unit 113 is a negative temperature coefficient thermistor, which has the characteristic that the higher the temperature, the smaller the resistance, and the lower the temperature, the greater the resistance. Since the electrode sheet 110 is applied to the human body surface during use, and the human body surface temperature is generally between 36°C and 37°C, a negative temperature coefficient thermistor with a temperature range of 0°C to 50°C can be selected. For example, you can choose the thermistor model NCP18XH103D03RB. When the sensed temperature is 0°C, the corresponding resistance is approximately 27.45KΩ; when the sensed temperature is 25°C, the corresponding resistance is approximately 10.0KΩ; when the sensed temperature is 50°C, the corresponding resistance is approximately 4.16KΩ.
[0079] 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 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 (the voltage value of the thermistor), as shown in the following formula (1):
[0080] VADC=(VCC-VD)×R / (Rz+R) (1)
[0081] Wherein, VADC is the AD sampling value, i.e., the voltage value, VCC is also used to represent the voltage of the DC power supply, VD is the voltage drop of the diode 115 , R is the resistance of the thermistor, and Rz is the resistance of the voltage divider resistor 123 .
[0082] Assuming that the voltage drop VD of the diode 115 is 0.3V, and the resistance Rz of the voltage dividing resistor 123 is 10KΩ, when the temperature sensor 114 senses a temperature of 0℃, the corresponding resistance is about 27.45KΩ, and based on the 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 sensor 114 senses a temperature of 25℃, the corresponding resistance is about 10.0KΩ, and based on the formula (1), the corresponding AD sampling value V25=(3.3-0.3)×10 / (10+10)=1.50V can be obtained; when the temperature sensor 114 senses a temperature of 50℃, the corresponding resistance is about 4.16KΩ, and based on the 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 is 3.3V. When the temperature sensor 114 and the diode 115 are short-circuited, the corresponding AD sampling value is 0V.
[0083] Since the ADC unit 122 collects the voltage value of the temperature sensor 114, the temperature sensor 114 detects different temperatures, and each temperature has a corresponding different voltage value, the voltage value collected by the ADC unit 122 can be reasonably segmented for differentiation, and the voltage value can be converted into a corresponding code, i.e., different voltage intervals of the voltage value correspond to different codes, and based on the code, the test code array of the electrode sheet 110 can be determined. The test code array includes at least one of a first code, a second code, and a third code, wherein the first code is used to indicate that the temperature detection unit 113 is in a normal state, the second code is used to indicate that the temperature detection unit 113 is in a disconnected state or an unset state, and the third code is used to indicate that the temperature detection unit 113 is in a short-circuit state.
[0084] Specifically, taking the temperature sensor 114 sensing a temperature in the range of 0℃-50℃ and the AD sampling value, i.e., the voltage value, obtained by the ADC unit 122 being in the range of 0.88V-2.20V as an example, considering the detection error factors, etc., the range of the voltage value can be appropriately enlarged to 0.5V-3V.
[0085] When the AD sampled value obtained by the ADC unit 122 is greater than 0.5V and less than 3V, the corresponding code is a first code, such as 1; when the AD sampled value obtained by the ADC unit 122 is less than or equal to 0.3V, the corresponding code is a third code, such as 0; and when the AD sampled value obtained by the ADC unit 122 is greater than or equal to 3.1V, the corresponding code is a second code, such as 2. Therefore, in the corresponding detection bits numbered 1 to 20 of the electrode sheet 110, if the temperature sensor 114 is short-circuited, the corresponding code is 0, i.e., the third code; if the temperature sensor 114 is present, the corresponding code is 1, i.e., the first code; and if the temperature sensor 114 is absent or disconnected, the corresponding code is 2, i.e., the second code.
[0086] refer to Figure 2 As shown, under normal circumstances, 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 temperature sensors 114, and the codes are all 1, the 20 codes are combined to obtain the 20-bit standard code array 11111 11111 11111 11111 of the electrode sheet 110. When the temperature sensor 114 is short-circuited, assuming that the temperature sensor 114 at the detection position numbered 1 is short-circuited, the 20-bit test code array obtained is 21111 11111 11111 11111. When the temperature sensor 114 is short-circuited, assuming that the temperature sensor 114 at the detection position numbered 1 is short-circuited, the 20-bit test code array obtained is 01111 11111 11111 11111.
[0087] Based on the above coding rules, the quality of the electrode sheet 110 can be checked during use so that the electrode sheet 110 can be replaced in time to avoid low-temperature burns. The specific process is as follows:
[0088] Step 1: Provide at least one pair of qualified electrode sheets 110 (since the electrode sheets 110 are medical devices, each electrode sheet 110 undergoes multiple tests before leaving the factory to ensure that the electrode sheets 110 are qualified. Therefore, the electrode sheets 110 provided to the user are all qualified electrode sheets 110). Connect the at least one pair of qualified electrode sheets 110 to the aforementioned adapter 120, and connect the aforementioned adapter 120 to the aforementioned electric field generator 130.
[0089] Step 2: Power on the electric field generator 130 to provide a DC power supply VCC to the temperature detection unit 113 in at least one pair of qualified electrode sheets 110 for temperature detection. The ADC unit 122 in the adapter 120 collects the analog temperature signals detected by the temperature detection unit 113 of at least one pair of qualified electrode sheets 110, obtaining a plurality of 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 coding 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.
[0090] Step 3: Turn off the power of the electric field generator 130 and place the at least one pair of qualified electrode sheets 110 on the body surface corresponding to the tumor portion of the patient.
[0091] Step 4: Power on the electric field generator 130 to provide a DC power supply VCC to the temperature detection unit 113 in at least one pair of qualified electrode sheets 110 for temperature detection. Simultaneously, it provides an alternating electrical signal to the electrode units 112 in the electrode sheets 110, thereby forming an alternating electric field between the paired electrode sheets 110 for tumor electric field therapy. The ADC unit 122 in the adapter 120 collects the temperature signals detected by the temperature detection units 113 in at least one pair of qualified electrode sheets 110, obtaining a plurality of 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.
[0092] 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, steps 4 and 5 are repeated. If at least one of the detection code arrays B1' or B2' is inconsistent with the standard code arrays A1 and A2, step 6 is performed.
[0093] Step 6: The adapter 120 confirms the number of abnormal temperature detection units 113 in the electrode sheet 110 corresponding to the inconsistent detection code array B1' and / or B2', and determines whether the number of abnormal temperature detection units 113 in the corresponding electrode sheet 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.
[0094] Step 7: Continue to repeat steps 4 and 5.
[0095] Step 8: The adapter 120 issues an alarm by controlling the reminder unit (not shown) inside it, 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 electric signals to the electrode unit 112 in the electrode sheet 110, reminding the user to replace the corresponding electrode sheet 110.
[0096] Step nine: Turn off the power of the electric field generator 130 , remove the electrode sheet 110 to be replaced from the adapter 120 , and connect a new electrode sheet 110 to the adapter 120 .
[0097] Step 10: Power on the electric field generator 130 and continue to provide a DC power supply VCC to the temperature detection unit 113 in the electrode sheet 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 sheet 110 to obtain a number of AD sampling values. The first controller 121 in the adapter 120 obtains a new standard coding array A1' or / and A2' according to the aforementioned coding rules. At least one set of new standard coding arrays A1' or / and A2' is compared with the corresponding stored standard coding arrays A1 or / and A2. If the new standard coding arrays A1' or / and A2' are consistent with the standard coding arrays A1 or / and A2, the electric field generator 130 is turned off. Source, place the replaced new electrode sheet 110 on the body surface corresponding to the tumor part of the patient, and then loop steps four and five; if after comparing the new standard coding array A1' or / and A2' with the aforementioned stored standard coding arrays A1 or / and A2 one by one, there is at least one set of new standard coding arrays A1' and / or A2' that is inconsistent with the aforementioned stored and corresponding standard coding arrays A1 and / or A2, then loop steps nine and ten until the new standard coding arrays A1' and / or A2' of the replaced qualified electrode sheet 110 are consistent with the aforementioned stored and corresponding standard coding arrays A1 and / or A2.
[0098] It should be noted that in the above steps, the paired electrode sheets 110 may be electrode sheets 110 of the same design, that is, the paired electrode sheets 110 have the same standard coding arrays, that is, the standard coding arrays A1 and A2 are the same.
[0099] The above steps 1 and 2 can be replaced by the user inputting at least two sets of standard code arrays A1 and A2. The at least two sets of standard code arrays A1 and A2 can be stored in the adapter 120 and used as comparison codes.
[0100] In the above step six, the number of abnormal temperature detection units 113 in the corresponding electrode sheet 110 is determined by the number of codes that are different when the inconsistent detection code array A1' and / or A2' is compared with the corresponding standard code arrays A1 and A2. For example, when A1' is compared with A1, only the first code is different, then the number of abnormal temperature detection units 113 in the corresponding electrode sheet 110 is 1; for another example, when A1' is compared with A1, only the last two codes are different, then the number of abnormal temperature detection units 113 in the corresponding electrode sheet 110 is 2; and so on.
[0101] In step 6 above, the upper limit can be set to 1, indicating that one temperature detection unit 113 on the electrode sheet 110 is abnormal, and step 8 is executed to generate an alarm and replace the electrode sheet 110. In other embodiments, in step 6 above, the upper limit is not limited to 1, but can be a positive integer close to the ratio of the number of temperature detection units 113 on the electrode sheet 110.
[0102] In step eight above, the reminder unit (not shown) may include at least two indicator lights (not shown) corresponding to each electrode pad 110, indicating the status of the corresponding electrode pad 110. When the electrode pad 110 does not need to be replaced, the indicator lights (not shown) corresponding to the electrode pad 110 to be replaced will light up green; when the electrode pad 110 needs to be replaced, the indicator lights (not shown) corresponding to the electrode pad 110 to be replaced will light up red. Alternatively, the indicator lights (not shown) may be permanently lit or flashing to indicate whether the electrode pad 110 does not need to be replaced or needs to be replaced.
[0103] In step eight above, the reminder unit (not shown) may further include a buzzer (not shown) to indicate the status of the electrode pad 110 and to alert the user simultaneously with the indicator light (not shown). When the electrode pad 110 does not need to be replaced, the buzzer (not shown) does not sound an alarm; when the electrode pad 110 needs to be replaced, the buzzer (not shown) sounds an alarm.
[0104] While comparing the detection code array with the standard code array in steps 4, 5, and 6 above, temperature monitoring is also performed simultaneously. The steps include the following:
[0105] Step 11: The first controller 121 in the adapter 120 calculates the digital temperature signal detected by the temperature detection unit 113 based on a number of 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 sheet 110 exceeds the preset temperature, proceed to step 12; if the digital temperature signals detected by the temperature detection unit 113 of the electrode sheet 110 are all below the preset temperature, continue to step 11.
[0106] 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 sheet 110 exceeds a preset temperature, it sends a corresponding signal via the first communication unit 126, causing the electric field generator 130 to reduce or shut down the corresponding alternating electric signal until the temperature detected by the temperature detection unit 113 of the corresponding electrode sheet 110 is below the preset temperature. The preset temperature range can be 39°C to 41°C, preferably 40.5°C.
[0107] It should be noted that the above process is described using the adapter 120 as an example of quality monitoring of the electrode sheet 110. 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. The details are not repeated here. In addition, the number of electrode sheets 110, the number of electrode units 112 of each electrode sheet 110, and the setting of the sampling code are all illustrative and do not limit the present application.
[0108] Specifically, during the production process of the electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can send the test code array of the electrode sheet 110 to the host computer (not shown), so that the host computer (not shown) can compare the test code array with the standard code array for consistency to monitor whether each temperature detection unit 113 of the electrode sheet 110 is connected normally, and then determine whether the electrode sheet 110 is qualified, so as to screen out unqualified electrode sheets 110, thereby ensuring that each temperature detection unit 113 of the electrode sheet 110 shipped from the factory can be detected normally. Among them, the standard code array includes at least the first code of the first code and the second code. The specific process is as follows:
[0109] Step 1: Provide a qualified electrode sheet 110, connect the electrode sheet 110 to the aforementioned adapter 120, connect the aforementioned adapter 120 to the aforementioned electric field generator 130, and further connect the aforementioned electric field generator 130 to a host computer (not shown), which is further connected to a display (not shown) so that the host computer (not shown) controls the display (not shown) to display the coding array (i.e., standard coding array) of the qualified electrode sheet 110 and the coding array (i.e., test coding array) of the tested electrode sheet 110' of the same batch and specification as the qualified electrode sheet 110.
[0110] Step 2: Power on the electric field generator 130 to provide a DC power supply VCC to the temperature detection unit 113 of the qualified electrode sheet 110 for temperature detection. The aforementioned adapter 120 obtains a set of standard coding arrays A according to the aforementioned coding rules. The standard coding array A is routed by the aforementioned adapter 120 through the aforementioned electric field generator 130 to the host computer (not shown), and finally stored in the host computer (not shown) as a standard coding array for comparison.
[0111] Step 3: Provide a tested electrode sheet 110' that is from the same batch and specification as the qualified electrode sheet 110, connect the tested electrode sheet 110' to the aforementioned adapter 120, and the aforementioned adapter 120 obtains a set of test code arrays 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).
[0112] Step 4: The host computer (not shown) compares the test code array B with the standard code array A for consistency. If the test code array B is consistent with the standard code array A, proceed to step 5; if the test code array B is inconsistent with the standard code array A, proceed to step 6.
[0113] Step 5: The display (not shown) shows that the electrode sheet 110 ′ under test is “qualified”, and the electrode sheet 110 ′ under test is placed in the good product area. Then, steps 3 to 4 are repeated to test the next electrode sheet 110 ′ under test.
[0114] Step 6: The display (not shown) shows that the electrode sheet 110 ′ under test is “failed”, and the electrode sheet 110 ′ under test is placed in a defective product area. Then, steps 3 to 4 are repeated to test the next electrode sheet 110 ′ under test.
[0115] In step 6, while the display (not shown) indicates that the electrode sheet 110' under test is "failed," the host computer (not shown) can also control an alarm (not shown) to sound an alarm, thereby alerting the operator that the electrode sheet 110' under test is "failed" and needs to be placed in a defective product area. The alarm (not shown) can sound an alarm, a light alarm, or the like.
[0116] It should be noted that, through the above-mentioned quality inspection steps for the electrode sheets 110, the standard code arrays of various qualified electrode sheets 110 can be stored in a host computer (not shown) to form a standard code array library of qualified electrode sheets 110. When the electrode sheets 110' under test with the same specifications are tested again, the corresponding standard code array A in the standard code array library can be called as the comparison code for the inspection of the batch of electrode sheets 110' under test, and compared with the test code array B corresponding to the electrode sheets 110' under test, and a judgment can be made as to whether the batch of electrode sheets 110' under test is qualified.
[0117] 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 a multi-bit coding arrangement, which is not limited to the above Figure 2 The 20-bit code combination corresponding to the electrode sheet 110 of the embodiment can be a combination of 13-bit, 24-bit, etc. codes.
[0118] The above steps are described using the adapter 120 as an example to perform quality inspection on the electrode sheet 110. The electric field generator 130 can also be used to perform quality inspection on the electrode sheet 110. In addition, the number of electrode sheets 110 that can be connected to the adapter 120, the number of electrode units 112 in each electrode sheet 110, and the setting of the sampling code are all exemplary and do not limit the present application.
[0119] It should be noted that in the embodiment of the present application, the control switch 124 electrically connected to each of the multiple grounding lines 118 of the electrode sheet 110 and the bidirectional switch 125 electrically connected to each of the multiple dual-purpose signal lines 119 of the electrode sheet 110 are both provided in the adapter 120.

In addition, the ADC unit 122 provided in the adapter 120 may also be provided in the electric field generator 130 and directly controlled by the second controller 131.

While it can transmit both alternating electrical signals and direct current signals for temperature signal acquisition and the acquired temperature detection signals through the dual-purpose signal line, it also greatly reduces the number of conductive traces (grounding wires, dual-purpose signal lines) laid thereon, reduces the wiring difficulty of the substrate, simplifies the manufacturing process, reduces the weight of the substrate, 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 without increasing the wire core of the first cable electrically connected to the electrode sheet, thereby realizing quality detection of the electrode sheet.
[0140] In the tumor electric field therapy system of the present application, an adapter of the same specification and model can adapt to a variety of electrode sheets with different numbers of ground wires and dual-purpose signal lines. Although the adapter may have suspended bidirectional switching switches and / or control switches corresponding to different electrode sheets, its adaptability is improved.

[0144] S120: Determine the test code array of the electrode sheet according to the temperature detection signal.
[0145] Specifically, the temperature detection signal is represented by a voltage value, and a test code array of the electrode sheet 110 is determined based on the temperature detection signal, including: determining the voltage interval in which the voltage value is located; determining the code corresponding to the corresponding temperature detection unit 113 based on the voltage interval in which the voltage value is located, wherein different voltage intervals in which the voltage value is located correspond to different codes; and generating a test code array for the corresponding electrode sheet 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 is used to indicate that the temperature detection unit 113 is in a normal state, the second code is used to indicate that the temperature detection unit 113 is in an open circuit state or an unset state, and the third code is used to indicate that the temperature detection unit 113 is in a short circuit state.

[0148] After the test code array is compared with the standard code array for consistency, the number of faulty temperature detection units 113 in the electrode sheet 110 is determined, and a determination is made based on the number of faulty temperature detection units 113 in the electrode sheet 110 whether the electrode sheet 110 should be replaced. If it is determined that the electrode sheet 110 needs to be replaced, the tumor therapeutic field system 100 is controlled to issue a second reminder message and the electric field generator 130 is controlled to stop operating.
[0149] Specifically, during the production process of the electrode sheet 110, the test code array and the standard code array can be compared for consistency to determine whether the corresponding electrode sheet 110 is qualified, thereby achieving quality inspection of the electrode sheet 110 during the production process. After determining whether the corresponding electrode sheet 110 is qualified, the test code array of the electrode sheet 110, the standard code array, and the result of the determination of whether the electrode sheet 110 is qualified can also be displayed, and a corresponding reminder message can be issued if the electrode sheet 110 is unqualified.
