Abstract
Description
Technical Field
[0001] This application relates to the technology of Tumor Treating Fields (TTF), and particularly to a method for detecting the temperature of an electrode patch and a method for applying an alternating current signal for tumor treatment. Background Art
[0002] Tumor Treating Fields is a method that inhibits the formation of spindle microtubules during the mitosis of certain tumor cells through low-intensity medium-high frequency alternating electric fields, thereby inhibiting the separation of intracellular organelles during the cell division phase and inducing apoptosis of cells in the mitosis phase, so as to achieve the purpose of treating tumors.
[0003] Compared with traditional cancer treatment methods, TTF has an innovative mechanism of action. Some physiological characteristics of tumor cells, such as geometric shape and high-frequency mitosis, make them vulnerable to TTF. TTF disrupts the normal aggregation of tubulin by applying a directional force on intracellular polar particles (such as macromolecules and organelles). These processes may lead to physical damage to the cell membrane and apoptosis. At the end of cell mitosis, the structural morphology of the cleavage furrow causes uneven electric field distribution around it. At the same time, under the influence of TTF, the electric field intensity at the cleavage furrow is significantly enhanced, and charged substances in the cell move towards the cleavage furrow, interfering with or even destroying the formation of the cell structure, and ultimately leading to the failure of cell division and apoptosis.
[0004] In existing tumor electric field treatment systems, an electric field generating device is used to transmit an alternating current signal for tumor electric field treatment to an electrode patch, and then an alternating electric field is applied to the tumor site of the patient through the electrode patch for tumor electric field treatment. When the tumor treatment electric field is applied to the patient's body, heat will accumulate at the electrode patch attachment site, and the temperature of the electrode patch attachment site will also increase accordingly. Therefore, it is necessary to continuously monitor the temperature at the electrode patch attachment site. When the monitored temperature rises to a certain preset value, it is necessary to timely adjust the electric field intensity applied to the tumor site of the patient to avoid scalding the patient's skin due to excessive temperature at the electrode patch attachment site.
[0005] The tumor electro - field therapy system includes at least a pair of electrode patches. There are multiple electrode units in each electrode patch. Even if the same alternating - current signal is applied to each electrode unit, the heat generated on each electrode unit will vary due to its different positions. That is, the temperatures of each electrode unit on the entire electrode patch will not be exactly the same. In this way, it is possible that the temperatures of some electrode units in the entire electrode patch exceed the preset temperature while the temperatures of other electrode units are normal. In order to ensure that there is a sufficient application time in tumor electro - field therapy while avoiding causing low - temperature burns on the patient's body surface, it is necessary to implement individual control for the over - temperature electrode units. However, for existing electrode patches, implementing individual control for electrode units requires setting a conductive trace for each electrode unit in the substrate of the electrode patch. This will increase the number of conductive traces in the electrode - patch substrate, making the electrode patch difficult to bend, and the cable electrically connected to the electrode patch will also thicken, increasing the overall weight of the electrode patch, which is not conducive to the application of the electrode patch.
[0006] Therefore, it is necessary to provide an electrode - patch temperature - detection method that uses fewer conductive traces to perform zonal control on multiple electrode units. Summary of the Invention
[0007] The purpose of this application is to provide an electrode - patch temperature - detection method and an alternating - current signal application method for tumor electro - field therapy to solve or eliminate problems in related technologies.
[0008] To achieve the above object, the present application provides the following technical solution: An electrode sheet temperature detection method is applied to an electrode sheet that applies an alternating current signal to inhibit tumor growth or inhibit mitosis of cancer cells to a tumor site or a tumor tissue culture. The electrode sheet includes: a plurality of dielectric elements for applying an alternating current signal; a plurality of temperature sensors for detecting the temperature at corresponding parts of the corresponding dielectric elements, the plurality of temperature sensors are respectively arranged in one-to-one correspondence with the plurality of dielectric elements and are configured as a plurality of row groups and a plurality of column groups in electrical connection; a plurality of ground wires, respectively corresponding to the plurality of row groups one by one, and each ground wire is configured to short-circuit and ground the ground terminals of the temperature sensors in the corresponding row group; and a plurality of dual-purpose signal lines, respectively corresponding to the plurality of column groups one by one, and each dual-purpose signal line is simultaneously connected to the signal terminals of the temperature sensors in the corresponding column group and the corresponding dielectric elements in the corresponding column group and switches between transmitting a direct current signal to the temperature sensors in the corresponding column group to collect temperature detection signals and transmitting an alternating current signal to the dielectric elements in the corresponding column group for tumor treatment; the method includes: transmitting a direct current signal to the plurality of dual-purpose signal lines of the electrode sheet; and sequentially and time-divisionally turning on each ground wire of the electrode sheet to collect the temperature detection signals detected by the temperature sensors in each row group of the corresponding electrode sheet row by row; or transmitting a direct current signal to any one of the dual-purpose signal lines in the electrode sheet; and sequentially and time-divisionally turning on each ground wire of the electrode sheet to collect the temperature detection signals detected by the temperature sensors in the corresponding column group one by one.
[0009] Further, transmitting a direct current signal to the plurality of or any one of the dual-purpose signal lines of the electrode sheet is performed after stopping the application of the alternating current signal to the electrode sheet.
[0010] Further, stopping the application of the alternating current signal to the electrode sheet is achieved by stopping transmitting the alternating current signal to each of the dual-purpose signal lines.
[0011] Further, each of the ground wires is disconnected when the dual-purpose signal line transmits an alternating current signal to the dielectric elements in the corresponding column group for tumor treatment.
[0012] Further, the plurality of ground wires are sequentially and time-divisionally closed when the dual-purpose signal line transmits a direct current signal to the temperature sensors in the corresponding column group to collect temperature detection signals, and only one of the ground wires is turned on at the same time, and the rest of the ground wires are all disconnected.
[0013] Further, the method further includes: converting the collected temperature detection signals to obtain respective digital temperature signals; and determining the temperature at the corresponding parts of the respective dielectric elements based on the respective digital temperature signals.
[0014] Further, each ground wire is electrically connected to a grounding switch, and each dual-purpose signal wire is electrically connected to a bidirectional switching switch. The temperature detection signals collected from the temperature sensors are obtained by combining the control of the grounding switches and the bidirectional switching switches.
[0015] Further, the switching between transmitting a DC signal to each temperature sensor in the corresponding column group to collect temperature detection signals and transmitting an AC signal to each dielectric element in the corresponding column group for tumor treatment of the dual-purpose signal wire is achieved by combining the control of the corresponding bidirectional switching switch and each grounding switch.
[0016] Further, the bidirectional switching switch has a fixed end electrically connected to the corresponding dual-purpose signal wire, a collection end that conducts with the fixed end to transmit a DC signal, and an input end that conducts with the fixed end to transmit an AC signal. When the dual-purpose signal wire electrically connected to it transmits an AC signal, the fixed end and the input end of the bidirectional switching switch are conducted, or when the dual-purpose signal wire electrically connected to it transmits a DC signal, the fixed end and its collection end are conducted.
[0017] The present application also provides an AC signal application method for tumor electric field therapy, which controls or adjusts the AC signals applied to the dielectric elements of the electrode plate according to the temperature detection signals obtained by the above method.

Detailed implementation
[0062] The embodiments of the technical solutions of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solutions of the present application more clearly, so they are only examples and cannot be used to limit the protection scope of the present application.
[0063] Figure 1 Shown is a schematic diagram of a tumor electrotherapy system 100 according to an embodiment of the present application. As Figure 1 shown, the tumor electrotherapy system 100 includes: at least a pair of electrode patches 10, an adapter 20 electrically connected to the electrode patches 10, and an electric field generator 30 electrically connected to the adapter 20. The electric field generator 30 generates an alternating current signal for tumor treatment and applies the alternating current signal to the electrode patches 10 through the adapter 20 to generate a treatment electric field between the paired electrode patches 10. The adapter 20 is electrically connected between the electrode patches 10 and the electric field generator 30 and is used to deliver the alternating current signal generated by the electric field generator 30 to the electrode patches 10. That is to say, the electric field generator 30 can generate an alternating current signal, and the generated alternating current signal is transmitted to each electrode patch 10 through the adapter 20, so as to generate a treatment electric field for treating tumors between the same pair of electrode patches 10.
[0064] As Figure 1 shown, in this embodiment, the number of electrode patches 10 is 4. From the perspective of spatial structure arrangement, each electrode patch 10 includes a plurality of electrode units 12 that are both axially symmetrically arranged and centrally symmetrically arranged and have the same number, a plurality of connecting parts 111 located between adjacent two electrode units 12, a bridging part 113 erected between adjacent two connecting parts 111, a wiring part 112 connected to the bridging part 113, and a first cable 13 connected to the wiring part 112. The bridging part 113 and the wiring part 112 are arranged perpendicular to each other to form a "T" shape. The bridging part 113 is erected between adjacent two connecting parts 111. Each electrode unit 12 of the electrode patch 10 is electrically connected to the adapter 20 through the first cable 13.
[0065] Each electrode unit 12 has a temperature sensor 14 and a dielectric element 15. The temperature sensor 14 is used to detect the temperature at which the electrode unit 12 is attached to the patient's body surface part. It can be a thermistor element or other temperature sensors other than thermistors, and can be set at any position on the electrode unit 12. The dielectric element 15 is used to apply an alternating current signal to the patient's tumor part. The dielectric element 15 can be a dielectric ceramic sheet or a polymer dielectric layer composed of a polymer material. In this embodiment, each dielectric element 15 has a through hole (not labeled) in the middle for accommodating a corresponding temperature sensor 14. Each electrode unit 12 may further include a diode 16 connected in series with the temperature sensor 14, which can prevent the reverse inflow of current to prevent the detection signal from other electrode units 12 from affecting the temperature sensor 14. The ground terminal 14-1 of the temperature sensor 14 is connected in series with the anode of the diode 16 and is grounded through the cathode of the diode 16.
[0066] The electrode unit 12 applies an alternating current signal through the dielectric element 15 in the first mode; in the second mode, it detects or collects the temperature of the patient's body surface where the corresponding electrode unit 12 is attached through the temperature sensor 14; in the third mode, it stops applying the alternating current signal and stops temperature detection and collection. The first mode, the second mode, and the third mode do not overlap in time periods. That is, the time period when the dielectric element 15 of the electrode unit 12 applies an alternating current signal is staggered and does not overlap with the time period when the temperature sensor 14 detects the temperature. The electrode unit 12 can cycle between applying an alternating current signal through its dielectric element 15 and detecting the temperature through its temperature sensor 14, that is, the electrode unit 12 can cycle between the first mode and the second mode. The electrode unit 12 can also cycle between the first mode, the second mode, and the third mode, that is, the electrode unit 12 cycles among applying an alternating current signal through the dielectric element 15, collecting or detecting the temperature through the temperature sensor 14, and stopping applying the alternating current signal and temperature collection.
[0067] Each electrode sheet 10 includes an electrode array (not labeled) composed of 20 electrode units 12. The electrode array (not labeled) also has a flexible circuit board 11 including a connection part 111, a wiring part 112, and a bridging part 113. The 20 electrode units 12 are all arranged at intervals in the electrode array (not labeled) arranged in four rows and six columns. Specifically, four electrode units 12 are arranged in each of the first row and the last row, and six electrode units 12 are arranged in each of the middle two rows. The four electrode units 12 in the first row are respectively located in the second to fifth columns, the six electrode units 12 in each of the middle two rows are respectively located in the first to sixth columns, and the four electrode units 12 in the last row are also respectively located in the second to fifth columns.
[0068] The connecting part 111 is only located between two adjacent electrode units 12 arranged in the column direction in each of the third column and the fourth column, and between the other two adjacent electrode units 12 adjacent in the row direction in each row but excluding the two electrode units 12 in the third column and the fourth column in each row. That is, between two adjacent electrode units 12 in the third column and the fourth column, they are only connected in the column direction by the connecting part 111, and are all in a disconnected state and not connected by the connecting part 111 in the row direction; the electrode units 12 in each of the first column, the second column, the fifth column, and the sixth column are only connected to the electrode units 12 adjacent to them in the row direction by the connecting part 111 arranged horizontally, and are all in a disconnected state between them in the column direction and the adjacent electrode units 12. That is to say, between two column - adjacent electrode units 12 in each of the first column, the second column, the fifth column, and the sixth column, they are all in a disconnected state.
[0069] The electrode unit 12 in the third column and the connecting part 111 arranged longitudinally between the electrode units 12 in this column, and the electrode unit 12 in the fourth column and the connecting part 111 also arranged longitudinally between the electrode units 12 in this column together constitute the main trunk 114 of the electrode array (not labeled). The connecting parts 111 located on the opposite sides of the two - column electrode units 12 in the third column and the fourth column and respectively connected to the electrode units 12 in the third column and the fourth column through the horizontally arranged connecting parts 111, and the electrode units 12 connected to the horizontally arranged connecting parts 111 together constitute the branches 115 of the electrode array (not labeled). That is to say, in this embodiment, the electrode array (not labeled) includes two main trunks 114 and several branches 115 respectively extending laterally from the two main trunks 114. Each branch 115 has a free end far from the main trunk 114, and the free ends of adjacent branches 115 are all in a disconnected state, and the positions and distances between adjacent branches 115 can be freely adjusted according to the actual usage scenario requirements. Specifically, one main trunk 114 is composed of the electrode units 12 in the third column and the connecting parts 111 arranged longitudinally between the adjacent electrode units 12 in this column, and the other main trunk 114 is composed of the electrode units 12 in the fourth column and the connecting parts 111 arranged longitudinally between the adjacent electrode units 12 in this column. The remaining electrode units 12 connected to the main trunk 114 through the horizontally arranged connecting parts 111 and the horizontally arranged connecting parts 111 are all branches 115.
[0070] Specifically, the several branches 115 are respectively: a connecting portion 111 that extends laterally to the left from the electrode unit 12 in the first row of the third column and is located in the first row, and an electrode unit 12 that is connected to the connecting portion 111 and is located in the second column of the first row; two connecting portions 111 that extend laterally to the left from the electrode unit 12 in the second row of the third column and are located in the second row, and two electrode units 12 that are located in the first column and the second column of the second row; two connecting portions 111 that extend laterally to the left from the electrode unit 12 in the third row of the third column and are located in the third row, and two electrode units 12 that are located in the first column and the second column of the third row; a connecting portion 111 that extends laterally to the left from the electrode unit 12 in the fourth row of the third column and is located in the fourth row, and an electrode unit 12 that is located in the second column of the fourth row; a connecting portion 111 that extends laterally to the right from the electrode unit 12 in the first row of the fourth column and is located in the first row, and an electrode unit 12 that is located in the fifth column of the first row; two connecting portions 111 that extend laterally to the right from the electrode unit 12 in the second row of the fourth column and are located in the second row, and two electrode units 12 that are located in the fifth column and the sixth column of the second row; two connecting portions 111 that extend laterally to the right from the electrode unit 12 in the third row of the fourth column and are located in the third row, and two electrode units 12 that are located in the fifth column and the sixth column of the third row; a connecting portion 111 that extends laterally to the right from the electrode unit 12 in the fourth row of the fourth column and is located in the fourth row, and an electrode unit 12 that is located in the fifth column of the fourth row.
[0071] The electrode array (not labeled) is divided into a symmetric left side portion including the left three columns and a right side portion including the right three columns, and the left side portion and the right side portion are only connected by the bridging portion 113. The left side portion is composed of a main trunk 114 located in the third column and several branches 115 that extend laterally to the left from the main trunk 114. The right side portion is composed of a main trunk 114 located in the fourth column and several branches 115 that extend laterally to the right from the main trunk 114. The two main trunks 114 are connected by the bridging portion 113 erected between them. Specifically, the two main trunks 114 are electrically connected by the bridging portion 113 erected between the connecting portion 111 connecting the electrode unit 12 in the second row of the third column and the electrode unit 12 in the third row of the third column and the connecting portion 111 connecting the electrode unit 12 in the second row of the fourth column and the electrode unit 12 in the third row of the fourth column. The connecting portion 111 connecting the electrode unit 12 in the second row of the third column and the electrode unit 12 in the third row of the third column, the connecting portion 111 connecting the electrode unit 12 in the second row of the fourth column and the electrode unit 12 in the third row of the fourth column, and the bridging portion 113 are arranged in a substantially "H" shape. In other embodiments, the bridging portion 113 may also be erected between an electrode unit 12 located in the third column and an electrode unit 12 located in the fourth column. Optionally, the bridging portion 113 is erected between two electrode units 12 that are adjacent in the row direction and are located in the third column and the fourth column.
[0072] According to their positions in the electrode array (not labeled), each electrode unit 12 can be divided into the electrode units 12 located at the periphery and the electrode units 12 located at the center. The electrode units 12 located at the periphery include four electrode units 12 in the first row, two electrode units 12 at the opposite ends of the second row, two electrode units 12 at the opposite ends of the third row, and four electrode units 12 in the fourth row. The electrode units 12 located at the center include four electrode units 12 in the middle of the second row and four electrode units 12 in the middle of the third row. Among the multiple electrode units 12 located at the periphery, some adjacent two electrode units 12 are connected by a horizontally arranged connecting portion 111, and some adjacent two electrode units 12 are arranged in a disconnected state. Among the multiple electrode units 12 located at the periphery, the adjacent two electrode units 12 connected by the connecting portion 111 are some row-adjacent two electrode units 12. Specifically, among the multiple electrode units 12 located at the periphery, the two column-adjacent and diagonally adjacent electrode units 12 are all arranged in a disconnected state; some row-adjacent two electrode units 12 are also arranged in a disconnected state; only some row-adjacent two electrode units 12 are connected by a horizontally extending connecting portion 111. Among the multiple electrode units 12 located at the center, only the column-adjacent two electrode units 12 on the main trunk 114 are connected by a vertically arranged connecting portion 111, and only the row-adjacent two electrode units 12 on the branch 115 are connected by a horizontally arranged connecting portion 111.
[0073] The electrode array (not labeled) also has intervals (not labeled) formed between several spaced-apart electrode units 12, which can allow the moisture on the patient's body surface to escape, enable heat exchange between the patient's body surface skin and the outside world, or allow the patient's body surface skin to breathe freely, and also allow the branches 115 to freely adjust their positions and spacings, and can also avoid wrinkles when the electrode patch 10 is applied. The intervals (not labeled) include a first interval D1 between the two main trunks 114 and a second interval D2 between the branches 115. The first interval D1 is located between the third-column electrode unit 12 and the fourth-column electrode unit 12, and the second interval D2 is located between the electrode units 12 in adjacent rows. That is, in the row direction, the electrode unit 12 in the third column and the adjacent electrode unit 12 in the fourth column are disconnected, and no connecting portion 111 is provided but the aforementioned first interval D1 is formed; and in the column direction, only the two column-adjacent electrode units 12 in the third column and the fourth column are connected by the connecting portion 111, and the two column-adjacent electrode units 12 in each of the other four columns are not connected by the connecting portion 111 but form the aforementioned second interval D2. The settings of the first and second intervals D1 and D2 can also increase the freedom of some electrode units 12 and can also avoid wrinkles when attaching the electrode patch 10.
[0074] In some other embodiments, the tumor treating electric field system 100 may also have more or fewer electrode patches 10. In some other embodiments, each pair of electrode patches 10 has the same number of electrode units 12, and different pairs of electrode patches 10 may also have different numbers of electrode units 12. In some other embodiments, the 20 electrode units 12 may also be arranged in other ways. Of course, in some other embodiments, the electrode patches 10 may also have other numbers of electrode units 12. In short, the implementation of the present application is not limited by the number and arrangement form of the electrode units 12 of the electrode patches 10.
[0075] Figure 2 The illustrated electrode patch 10' is Figure 1 a variant embodiment of the electrode patch 10 shown in. The spatial structure of the electrode patch 10' is the same as that of the electrode patch 10, and it also includes a plurality of electrode units 12' arranged at intervals, a number of connecting portions 111' located between two adjacent electrode units 12', a wiring portion 112' connected to the bridging portion 113', a first cable 13' connected to the wiring portion 112', a first interval D1 formed between the third column of electrode units 12' and the fourth column of electrode units 12', and a second interval D2' formed between adjacent rows of electrode units 12'; the difference is only that: two column - adjacent electrode units 12' in the fourth column are both in a disconnected state and not connected by a longitudinally arranged connecting portion 111', but two column - adjacent electrode units 12' in the fifth column are connected by a longitudinally arranged connecting portion 111', and each electrode unit 12' in the fourth column is connected to a row - adjacent electrode unit 12' in the fifth column by a laterally arranged connecting portion 111'; and the bridging portion 113' is connected between two electrode units 12' located in the third row and the third column and the third row and the fourth column.
[0076] Figure 3 is Figure 1 a schematic circuit connection diagram of the first embodiment of the electrode patch 10 for the tumor treating electric field system 100 or its variant embodiment electrode patch 10' and the adapter 20 of the first embodiment. It should be noted that: Figure 3 The arrangement of the illustrated electrode units 12 is for more clearly showing the electrical connection situation between an electrode patch 10 and the adapter 20, Figure 3 The arrangement of the illustrated electrode units 12 does not represent the arrangement of the electrode units 12 in the spatial structure. The following takes the electrode patch 10 in the first embodiment as an example for circuit connection description. Combining Figure 1 and Figure 3, the flexible printed circuit board 11 is embedded with multiple conductive traces 18, 19. The multiple conductive traces 18, 19 include multiple ground lines 18 and multiple dual-purpose signal lines 19. The first cable 13 has multi-core wires (not shown) that are respectively and electrically connected to the multiple ground lines 18 and the multiple dual-purpose signal lines 19 of the flexible printed circuit board 11 in a one-to-one correspondence. The total number of the ground lines 18 and the dual-purpose signal lines 19 embedded in the flexible printed circuit board 11 does not exceed 10. Therefore, the number of wires of the first cable 13 does not exceed 10.
[0077] In this embodiment, each electrode plate 10 is provided with 20 electrode units 12. The 20 electrode units 12 are sorted and grouped in the order of 1 to 20 in terms of circuit connection, and are divided into four row groups and five column groups, that is, the 20 electrode units 12 are arranged in four rows and five columns in terms of circuit connection. The temperature sensor 14 of each electrode unit 12 includes a ground terminal 14-1 and a signal terminal 14-2. The dielectric element 15 and the temperature sensor 14 of each electrode unit 12 are both welded to the flexible printed circuit board 11, and each dielectric element 15 is short-circuited with the signal terminal 14-2 of the corresponding temperature sensor 14. Since the electrode units 12 are arranged in four rows and five columns in terms of circuit connection, and each electrode unit includes a corresponding dielectric element 15 and a corresponding temperature sensor 14, therefore, the multiple temperature sensors 14 are also arranged in four row groups and five column groups in terms of circuit connection, and the multiple dielectric elements 15 are also arranged in four row groups and five column groups in terms of circuit connection. It should be noted that this arrangement method is to more clearly show the electrical connection situation between the electrode plate 10 and the adapter 20, and does not represent the arrangement of the electrode units 12 in the spatial structure. Its spatial structure may be a structure that is roughly in an array as Figure 1 shown, or other structures, such as petal-shaped or scattered-shaped, etc., which can be regular or irregular structures. The dielectric element 15 is configured to apply an alternating electric field to the tumor site of the patient. The temperature sensor 14 is configured to detect the temperature of the patient's body surface in contact with the electrode plate 10 and output a temperature detection signal to the adapter 20. In this embodiment, the multiple dual-purpose signal lines 19 of the flexible printed circuit board 11 are respectively and correspondingly arranged with multiple column groups of the electrode units 12, and are configured to transmit the alternating current signal generated by the electric field generator 30 to the dielectric element 15 in each electrode unit 12 of the corresponding column group. That is, the dielectric elements 15 located in the same column group are all short-circuited through the same dual-purpose signal line 19 of the flexible printed circuit board 11, and the dielectric elements 15 located in different column groups are respectively connected in parallel through different dual-purpose signal lines 19 of the flexible printed circuit board 11. The dual-purpose signal lines 19 of the flexible printed circuit board 11 are respectively and electrically connected to the corresponding wires in the first cable 13, and then are electrically connected to the electric field generator 30 through the adapter 20. That is, the dual-purpose signal lines 19 of the flexible printed circuit board 11 receive the alternating current signal generated by the electric field generator 30 through the first cable 13 and the adapter 20.
[0078] The multiple ground wires 18 are respectively arranged in one-to-one correspondence with multiple row groups of the electrode units 12, and the multiple ground wires 18 are respectively used to sequentially short-circuit the temperature sensors 14 of the corresponding electrode units 12 in each row group to the ground. That is, the ground terminals 14-1 of the multiple temperature sensors 14 in the same row group are all short-circuited through the same ground wire 18 of the flexible circuit board 11, and the ground terminals 14-1 of the temperature sensors 14 in different row groups are respectively connected to the ground in parallel through different ground wires 18 of the flexible circuit board 11. During the time period of temperature detection or in the second mode, only one of the multiple ground wires 18 is conducting at the same moment, and the rest are disconnected.
[0079] Each of the multiple multi-purpose signal lines 19 is also configured to respectively transmit a direct current signal to the temperature sensors 14 in each electrode unit 12 in the corresponding column group to collect and transmit the detected temperature signal. The signal terminals 14-2 of the multiple temperature sensors 14 in different column groups are respectively connected in parallel through different multi-purpose signal lines 19 of the flexible circuit board 11, and the signal terminals 14-2 of the multiple temperature sensors 14 in the same column group are all short-circuited to the same multi-purpose signal line 19 of the flexible circuit board 11. Specifically, each multi-purpose signal line 19 is configured to short-circuit the signal terminal 14-2 of the temperature sensor 14 of at most one electrode unit 12 in each row group to an external device for receiving the detection signal. Among them, the signal terminals 14-2 of the temperature sensors 14 connected by each multi-purpose signal line 19 are different from each other to avoid the subsequent output of repeated signals by the multi-purpose signal line 19. That is, when the number of electrode units 12 in a certain row group is the same as the number of multi-purpose signal lines 19, each multi-purpose signal line 19 is respectively electrically connected to the signal terminal 14-2 of the temperature sensor 14 of a different one of the electrode units 12 in this row group; when the number of electrode units 12 in a certain row group is less than the number of multi-purpose signal lines 19, there is at least one multi-purpose signal line 19 that is not electrically connected to the signal terminal 14-2 of the temperature sensor 14 of the electrode unit 12, and the remaining each multi-purpose signal line 19 is respectively electrically connected to the signal terminal 14-2 of the temperature sensor 14 of a different one of the electrode units 12 in this row group. In this embodiment, the external device for receiving the detection signal is the adapter 20. The multi-purpose signal line 19 of the flexible circuit board 11 receives a direct current signal from the adapter 20 or the electric field generator 30 through the first cable 13, and transmits the collected or detected temperature signal to the adapter 20, and then transmits it to the electric field generator 30 through the adapter 20.
[0080] In this embodiment, when a temperature sensor 14 is configured in each electrode unit 12 for temperature detection, the number of wires of the first cable 13 is reduced through the above circuit design, avoiding the cable from becoming thicker and the softness of the cable from becoming harder, which increases the difficulty of cable fixing; at the same time, it is avoided that the increase in the number of wires of the first cable 13 affects the adhesion effect between the electrode patch 10 and the corresponding body surface of the patient's tumor site. The ground wire 18 and the dual-purpose signal wire 19 embedded in the flexible printed circuit board 11 are a total of 9 circuits. Specifically, in this embodiment, the ground wire 18 embedded in the flexible printed circuit board 11 is 4 circuits, and the dual-purpose signal wire 19 is 5 circuits. In other embodiments, the number of circuits of the ground wire 18 and the dual-purpose signal wire 19 embedded in the flexible printed circuit board 11 may also have other numbers according to the circuit layout and quantity difference of the electrode units 12 in different electrode patches, which will be specifically described in subsequent embodiments.
[0081] In the tumor electric field therapy system 100, the number of conductive circuits electrically connected to the ground wire 18 is related to the number of row groups M of the electrode units 12, and it can be greater than or equal to the number of row groups of the electrode units 12, where M is a positive integer. In the tumor electric field therapy system 100, the number of conductive circuits electrically connected to the dual-purpose signal wire 19 is related to the number of column groups N of the electrode units 12, and it can be greater than or equal to the number of column groups of the electrode units 12, where N is a positive integer. The number of circuits L embedded in the flexible printed circuit board 11 of the electrode patch 10 is equal to the sum of the number of the ground wire 18 and the number of the dual-purpose signal wire 19. In this embodiment, the number of the ground wire 18 is equal to the number of row groups M of the electrode units 12; the dual-purpose signal wire 19 is equal to the number of column groups N of the electrode units 12.
[0082] In Figure 3In the illustrated embodiment, the electrode sheet 10 includes four ground wires 18, and each ground wire 18 is used to ground the ground terminals 14-1 of the temperature sensors 14 in the same row group. The four ground wires 18 of the electrode sheet 10 are respectively a first ground wire 18-1, a second ground wire 18-2, a third ground wire 18-3, and a fourth ground wire 18-4. Among the four row groups of the electrode sheet 10, the first row group includes electrode units 12-1 to 12-5, the second row group includes electrode units 12-6 to 12-10, the third row group includes electrode units 12-11 to 12-15, and the fourth row group includes electrode units 12-16 to 12-20. Specifically, the first ground wire 18-1 is used to ground the electrode units 12-1 to 12-5 in the first row group; the second ground wire 18-2 is used to ground the electrode units 12-6 to 12-10 in the second row group; the third ground wire 18-3 is used to ground the electrode units 12-11 to 12-15 in the third row group; and the fourth ground wire 18-4 is used to ground the electrode units 12-16 to 12-20 in the fourth row group. It should be noted that these ground wires 18 can be selectively closed or opened, which can be achieved by connecting each ground wire 18 in series with a switch, and this will be described in detail below. The above "grounding the electrode unit 12" may refer to grounding the ground terminal 14-1 of the temperature sensor 14 in the electrode unit 12, or may refer to connecting the diode 16 in series with the temperature sensor 14 of the same electrode unit 12 and grounding them together. In short, each ground wire 18 shorts and grounds the ground terminals 14-1 of the temperature sensors 14 of all the electrode units 12 in each row group.
[0083] Continue to refer to Figure 3As shown in the figure, the electrode sheet 10 of this embodiment further includes five two-purpose signal lines 19. One end of each two-purpose signal line 19 is respectively connected to all the electrode units 12 in each column group, and the other end is connected to an adapter 20 for receiving temperature detection signals and transmitting alternating current signals. That is to say, for each row group, each two-purpose signal line 19 can be selectively connected to one of the electrode units 12 or not connected to any of the electrode units 12 in that row group to avoid duplicate signals being output by the two-purpose signal line 19 subsequently. Specifically, the five two-purpose signal lines 19 of the electrode sheet 10 include a first two-purpose signal line 19-1, a second two-purpose signal line 19-2, a third two-purpose signal line 19-3, a fourth two-purpose signal line 19-4, and a fifth two-purpose signal line 19-5. One end of the first two-purpose signal line 19-1 is respectively and simultaneously connected to the dielectric elements 15 and the signal ends 14-2 of the temperature sensors 14 of the four electrode units 12, namely the electrode unit 12-1, the electrode unit 12-6, the electrode unit 12-11, and the electrode unit 12-16; one end of the second two-purpose signal line 19-2 is respectively and simultaneously connected to the dielectric elements 15 and the signal ends 14-2 of the temperature sensors 14 of the four electrode units 12, namely the electrode unit 12-2, the electrode unit 12-7, the electrode unit 12-12, and the electrode unit 12-17; one end of the third two-purpose signal line 19-3 is respectively and simultaneously connected to the dielectric elements 15 and the signal ends 14-2 of the temperature sensors 14 of the four electrode units 12, namely the electrode unit 12-3, the electrode unit 12-8, the electrode unit 12-13, and the electrode unit 12-18; one end of the fourth two-purpose signal line 19-4 is respectively and simultaneously connected to the dielectric elements 15 and the signal ends 14-2 of the temperature sensors 14 of the four electrode units 12, namely the electrode unit 12-4, the electrode unit 12-9, the electrode unit 12-14, and the electrode unit 12-19; one end of the fifth two-purpose signal line 19-5 is respectively connected to the dielectric elements 15 and the signal ends 14-2 of the temperature sensors 14 of the four electrode units 12, namely the electrode unit 12-5, the electrode unit 12-10, the electrode unit 12-15, and the electrode unit 12-20. In short, each two-purpose signal line 19 short-circuits in parallel the dielectric elements 15 and the signal ends 14-2 of the temperature sensors 14 of the respective electrode units 12 in the same column group and is used to connect to an external device. It should be noted that these two-purpose signal lines 19 can selectively transmit alternating current signals or receive temperature detection signals, which can be achieved by respectively connecting each two-purpose signal line 19 in series with a bidirectional switch 26 and coordinating the closing or opening of the ground wire 18, which will be described in detail below.
[0084] The multi-path ground wires 18 and the multi-path dual-purpose signal wires 19 are both conductive traces embedded in the flexible printed circuit board 11. The flexible printed circuit board 11 is electrically connected to the first cable 13. The multi-path ground wires 18 and the multi-path dual-purpose signal wires 19 embedded in the flexible printed circuit board 11 are respectively and electrically connected to corresponding wires (not shown) in the first cable 13 one by one.
[0085] The tumor electric field treatment system 100 of this embodiment includes at least a pair of the above-mentioned electrode plates 10, an adapter 20 electrically connected to the electrode plates 10, and an electric field generator 30 electrically connected to the adapter 20. The adapter 20 is connected between the electrode plates 10 and the electric field generator 30. The electric field generator 30 supplies an alternating current signal or supplies a direct current signal to the dielectric elements 15 in the plurality of electrode units 12 of the electrode plates 10 via the dual-purpose signal wires 19 of the adapter 20 and the electrode plates 10, and is used to receive the temperature detection signals output by the temperature sensors 14 in the plurality of electrode units 12. The adapter 20 is configured to deliver the alternating current signal generated by the electric field generator 30 to the dual-purpose signal wires 19 of the electrode plates 10, and is further configured to transmit a direct current signal to the dual-purpose signal wires 19 of the electrode plates and receive the temperature detection signals output by the multi-path dual-purpose signal wires 19 of the electrode plates 10.
[0086] Reference Figure 3 and Figure 4As shown, the adapter 20 includes: a first controller 22, multiple groups of analog-to-digital converters 23 connected to the first controller 22, multiple groups of voltage dividing resistors 24 corresponding to the multiple groups of analog-to-digital converters 23 one by one, multiple groups of ground switches 25 and multiple groups of bidirectional switching switches 26, a first communication unit 27, multiple AC signal lines 28 respectively connected to the multiple groups of bidirectional switching switches 26 one by one, and a first power module 29 connected to the first communication unit 27, the first controller 22, and the multiple groups of analog-to-digital converters 23 at the same time. The first power module 29 provides a DC power supply VCC for each electronic component of the adapter 20. The adapter 20 also includes multiple circuit lines (not labeled). Among them, the multiple circuit lines (not labeled) are respectively electrically connected to the multiple ground wires 18 and the multiple dual-purpose signal lines 19 in the flexible circuit board 11 of the corresponding electrode piece 10 through the first cable 13 of the corresponding electrode piece 10. The multiple circuit lines (not labeled) include multiple AC signal lines 28 that respectively transmit AC signal to the corresponding electrode piece 10 and are electrically connected to the multiple dual-purpose signal lines 19 in the flexible circuit board 11 of the corresponding electrode piece 10, multiple circuit lines (not labeled) that are respectively electrically connected to the multiple dual-purpose signal lines 19 in the flexible circuit board 11 of the corresponding electrode piece 10 one by one and are used to supply power to each temperature sensor 14 of the electrode piece 10 or transmit the temperature detection signal of the electrode piece 10, and multiple circuit lines (not labeled) that are respectively electrically connected to the multiple ground wires 18 in the flexible circuit board 11 of the corresponding electrode piece 10 one by one. The number P of circuit lines of the adapter 20 electrically connected to one electrode piece 10 is equal to the sum of the number of rows M and the number of columns N of the electrode unit 12 of the electrode piece 10 plus 1; the number H of circuits of the adapter 20 electrically connected to X electrode pieces 10 is equal to X times the number of circuit lines of it electrically connected to a single electrode piece 10, that is, H = XP = X*(M + N + 1). The number of groups of the ground switches 25 and the number of groups of the bidirectional switching switches 26 are both related to the number of the electrode pieces 10. The number of groups of the ground switches 25 is the same as the number of groups of the bidirectional switching switches 26; and is not less than the number of the electrode pieces 10. Preferably, the number of groups of the ground switches 25 and the bidirectional switching switches 26 are both the same as the number of the electrode pieces 10. The following only takes the electrical connection between an electrode piece 10 with 20 electrode units 12 and the adapter 20 as an example for detailed description.
[0087] Each group of ground switches 25 is provided with multiple ground switches 25. The multiple ground switches 25 are respectively connected into the adapter 20 and are respectively electrically connected to the circuit lines (not labeled) corresponding to the multiple ground wires 18 of the corresponding one electrode piece 10, and are configured to control the conduction or disconnection of the multiple ground wires 18. The circuit lines (not labeled) respectively and electrically connecting the multiple ground wires 18 of the electrode piece 10 are grounded at one end close to the ground switch 25. The number of ground switches 25 in each group of ground switches 25 is related to the number of ground wires 18 of the flexible circuit board 11 of the corresponding electrode piece 10, and the two are equal in this embodiment. AsFigure 3 As shown, in this embodiment, each group of grounding switches 25 has a plurality of grounding switches 25, which is 4 in this embodiment, namely the first grounding switch 25-1, the second grounding switch 25-2, the third grounding switch 25-3 and the fourth grounding switch 25-4. Each of the plurality of grounding switches 25 in each group respectively controls the closing or opening of the corresponding grounding wire 18 of a corresponding electrode plate 10. Specifically, the first grounding switch 25-1 is used to control the closing or opening of the first grounding wire 18-1 of the corresponding electrode plate 10, and then can cooperate with the corresponding group of bidirectional switching switches 26 to control the power-on and power-off of each temperature sensor 14 of the five electrode units 12 from the electrode unit 12-1 to the electrode unit 12-5 in the first row group of the electrode plate 10; the second grounding switch 25-2 is used to control the closing or opening of the second grounding wire 18-2 of the electrode plate 10, and then can cooperate with the corresponding group of bidirectional switching switches 26 to control the power-on and power-off of each temperature sensor 14 of the five electrode units 12 from the electrode unit 12-6 to the electrode unit 12-10 in the second row group of the electrode plate 10; the third grounding switch 25-3 is used to control the closing or opening of the third grounding wire 18-3 of the electrode plate 10, and then can cooperate with the corresponding group of bidirectional switching switches 26 to control the power-on and power-off of each temperature sensor 14 of the five electrode units 12 from the electrode unit 12-11 to the electrode unit 12-15 in the third row group of the electrode plate 10; the fourth grounding switch 25-4 is used to control the closing or opening of the fourth grounding wire 18-4 of the electrode plate 10, and then can cooperate with the corresponding group of bidirectional switching switches 26 to control the power-on and power-off of each temperature sensor 14 of the five electrode units 12 from the electrode unit 12-16 to the electrode unit 12-20 in the fourth row group of the electrode plate 10. The above-mentioned grounding switch 25 can be a mechanical switch, such as a relay. The grounding switch 25 can also be an electronic switch, and each grounding switch 25 can be opened and closed through the first controller 22 of the adapter 20.
[0088] In this embodiment, multiple groups of grounding switches 25 are all electronic switches. The first controller 22 is communicatively connected to multiple groups of grounding switches 25, and is used to sequentially and cyclically control the opening and closing states of the multiple grounding switches 25 in each group of grounding switches 25, and then sequentially and separately conduct each grounding wire 18 of the multiple grounding wires 18 of the corresponding electrode plate 10 and cooperate with the switching of the corresponding bidirectional switching switch 26 to sequentially and time-divisionally collect the temperatures of the patient's body surface detected by all the temperature sensors 14 on the electrode plate 10.

The plurality of bidirectional switching switches 26 in each group are respectively connected into the adapter 20 and are respectively electrically connected to circuit lines (not labeled) corresponding one-to-one to the multi-purpose signal lines 19 of a corresponding electrode plate 10. The number of bidirectional switching switches 26 in each group of bidirectional switching switches 26 is related to the number of multi-purpose signal lines 19 of the flexible circuit board 11 of the corresponding electrode plate 10, and is greater than or equal to the number of multi-purpose signal lines 19 of the flexible circuit board 11 of the corresponding electrode plate 10. In Figure 3 the illustrated embodiment, the two are equal. Each bidirectional switching switch 26 has two ends 1 and 2. The collection ends 1 of the plurality of bidirectional switching switches 26 in the same group are respectively electrically connected one-to-one to the corresponding detection channels among the plurality of detection channels of a corresponding group of analog-to-digital converters 23. The input ends 2 of each bidirectional switching switch 26 in the same group are electrically connected to the corresponding same AC signal line 28.

When the input end 2 of each group of bidirectional switches 26 is turned on and the acquisition end 1 is turned off, an alternating current signal can be transmitted to the dielectric elements 15 of each electrode unit 12 of the corresponding electrode plate 10. When the acquisition end 1 of each group of bidirectional switches 26 is turned on and the input end 2 is turned off, it can cooperate with each grounding switch 25 in the corresponding group of grounding switches 25 to transmit the temperature detection signal collected by the temperature sensors 14 of each electrode unit 12 on the electrode plate 10 in a time-sharing manner. The above-mentioned bidirectional switch 26 can be a mechanical switch, such as a relay. The bidirectional switch 26 can also be an electronic switch. The switching of the acquisition end 1 and the input end 2 of each bidirectional switch 26 can be controlled by the first controller 22 of the adapter 20.;
[0091] In this embodiment, multiple groups of bidirectional switches 26 are all electronic switches. The first controller 22 is communicatively connected to multiple groups of bidirectional switches 26 and is used to control multiple bidirectional switches 26 in each group of bidirectional switches 26 to switch between their respective acquisition ends 1 and input ends 2, and cooperate with the closing or opening of the corresponding grounding switch 25 to continuously monitor the temperature of the patient's body surface detected by all the temperature sensors 14 on the electrode plate 10 or transmit an alternating current signal to the patient.
[0092] In this embodiment, each group of analog-to-digital converters 23 is electrically connected to the acquisition ends 1 of a plurality of bidirectional switches 26 in the corresponding group of bidirectional switching switches 26 through a plurality of circuit lines (not labeled) in the adapter 20, and is configured to receive the temperature detection signals transmitted by the multi-purpose signal lines 19 of the corresponding electrode plates 10, and convert the temperature detection signals from analog signals into digital signals. Each group of analog-to-digital converters 23 includes a plurality of detection channels A, B, C, D, and E. Each detection channel A, B, C, D, and E is used to connect to a corresponding one of the multi-purpose signal lines 19 through the corresponding bidirectional switch 26. The number of detection channels in each group of analog-to-digital converters 23 is related to the number of bidirectional switches 26 in the corresponding group. The number of detection channels in each group of analog-to-digital converters 23 is related to the number of column groups of the electrode units 12 of the corresponding electrode plate 10. Specifically, the number of detection channels in each group of analog-to-digital converters 23 is equal to the number of bidirectional switches 26 in a corresponding group of bidirectional switching switches 26, and is not less than the number of column groups of the electrode units 12 of the corresponding electrode plate 10. As Figure 3 shown, each group of analog-to-digital converters 23 includes a total of 5 detection channels A, B, C, D, and E, namely 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.

Each detection channel A, B, C, D, and E is used to receive the temperature detection signals collected by the temperature sensors 14 of the electrode units 12 connected to the corresponding multi-purpose signal lines 19. In addition, each of the detection channels A, B, C, D, and E is connected to a first power supply module 29 for providing a detection voltage to this detection channel A, B, C, D, and E through a corresponding voltage-dividing resistor 24 in the adapter 20, and the first power supply module 29 provides a DC signal.
[0093] In this embodiment, the first communication unit 27 is configured to acquire digital signals output by multiple groups of analog-to-digital converters 23 and send the digital signals to the electric field generator 30. The electric field generator 30 is further configured to control and adjust the voltage or current or power of the alternating current signal provided to the multiple electrode units 12 of the electrode patch 10 according to the received digital signals. Exemplarily, when any one of the multiple received digital signals exceeds a preset threshold, it indicates that the temperature at the human body surface where the dielectric element 15 corresponding to at least one temperature sensor 14 in the electrode patch 10 is attached exceeds the preset threshold temperature (such as 41°C, 42°C, etc.). At this time, the voltage or current or power of the alternating current signal output by the electric field generator 30 can be appropriately reduced to avoid the temperature of the electrode units 12 of the electrode patch 10 being too high when applying the alternating current signal, causing low-temperature burns to the patient's skin. The above preset threshold temperature and preset threshold can be determined according to the human safety threshold. The first communication unit 27 is controlled by the first controller 22 and serially transmits the digital signals converted by the multiple groups of analog-to-digital converters 23. In this embodiment, the preset temperature threshold can be a value within 36°C - 45°C.

[0098] The following will refer toFigures 3 to 5 The working principle of the tumor electrotherapy system 100 of this embodiment will be introduced in detail.
[0099] Specifically, when it is necessary to detect the temperatures of the electrode units 12 of a certain electrode sheet 10, the first controller 22 of the adapter 20 or the second controller 32 of the electric field generator 30 controls each acquisition terminal 1 of each bidirectional switch 26 in a group of bidirectional switches 26 electrically connected to the electrode sheet 10 to conduct, and the input terminal 2 to disconnect, so as to disconnect the alternating current signal applied to the electrode sheet 10; at the same time, the first controller 22 of the adapter 20 or the second controller 32 of the electric field generator 30 controls each grounding switch 25 in a group of grounding switches 25 electrically connected to the electrode sheet 10 to conduct in sequence at different times. At this time, the temperature detection signals collected by the temperature sensors 14 of each electrode unit 12 in each row group of the electrode sheet 10 can be collected in sequence at different times through the multiple detection channels A, B, C, D, and E of a group of analog-to-digital converters 23 corresponding to the electrode sheet 10. Each detection channel A, B, C, D, and E of each group of analog-to-digital converters 23 only collects the temperature detection signals of the temperature sensors 14 of the corresponding electrode units 12 in the same row group of the electrode sheet 10 at the same time. The above temperature detection signals can be characterized by voltage values. Only 1 of the 4 grounding switches 25 in a group of grounding switches 25 corresponding to the electrode sheet 10 can conduct at the same moment, and the other 3 are disconnected. All 5 bidirectional switches 26 in a group of bidirectional switches 26 corresponding to the group of analog-to-digital converters 23 are switched to their respective acquisition terminals 1 so that the various two-way signal lines 19 of the electrode sheet 10 are electrically connected to the corresponding detection channels A, B, C, D, and E of the corresponding group of analog-to-digital converters 23 in a one-to-one correspondence and conduct. With such a setting, the group of analog-to-digital converters 23 can collect the voltage values of the temperature sensors 14 of the electrode units 12 in the same row group short-circuited by a ground wire 18 corresponding to the conducting grounding switch 25.
[0100] Specifically, when the first earthing switch 25-1 is closed, the second earthing switch 25-2, the third earthing switch 25-3 and the fourth earthing switch 25-4 are all open, and the first two-way switching switch 26-1, the second two-way switching switch 26-2, the third two-way switching switch 26-3, the fourth two-way switching switch 26-4 and the fifth two-way switching switch 26-5 are all switched to their respective acquisition ends 1, the temperature sensors 14 of the electrode units 12-1 to 12-5 in the first row group are powered on, and the temperature sensors 14 of the electrode units 12-6 to 12-20 in the remaining row groups are powered off. The signal terminals 14-2 of the temperature sensors 14 of the electrode units 12-1, 12-6, 12-11, and 12-16 are short-circuited by the first detection channel A in this group of analog-to-digital converters 23. Since only the grounding terminal 14-1 of the temperature sensor 14 of the electrode unit 12-1 is conductively grounded, while the grounding terminals 14-1 of the temperature sensors 14 of the electrode units 12-6, 12-11, and 12-16 are all open, and a diode 16 is provided in series with the temperature sensor 14 on each electrode unit 12, the remaining temperature sensors 14 in the first row do not affect the resistance value of the temperature sensor 14 of the electrode unit 12-1. Therefore, only the temperature sensor 14 of the electrode unit 12-1 operates effectively on the first detection channel A of this group of analog-to-digital converters 23, and the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature sensor 14 of the electrode unit 12-1. Similarly, the voltage value collected by the second detection channel B in this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-2. The voltage value collected by the third detection channel C in this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-3. The voltage value collected by the fourth detection channel D in this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-4. The voltage value collected by the fifth detection channel E in this analog-to-digital converter 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-5.
[0101] When the second earthing switch 25-2 is closed, the first earthing switch 25-1, the third earthing switch 25-3 and the fourth earthing switch 25-4 are all open, and the first double-way changeover switch 26-1, the second double-way changeover switch 26-2, the third double-way changeover switch 26-3, the fourth double-way changeover switch 26-4 and the fifth double-way changeover switch 26-5 are all switched to their respective acquisition ends 1, the temperature sensors 14 of the electrode units 12-6 to 12-10 in the second row group are powered on, and the temperature sensors 14 of the electrode units 12-1 to 12-5 and the electrode units 12-11 to 12-20 in the remaining row groups are powered off. The signal ends 14-2 of the temperature sensors 14 of the electrode units 12-1, 12-6, 12-11 and 12-16 are short-circuited by the first detection channel A in this group of analog-to-digital converters 23. Since only the grounding end 14-1 of the temperature sensor 14 of the electrode unit 12-6 is conductively grounded, while the grounding ends 14-1 of the temperature sensors 14 of the electrode units 12-1, 12-11 and 12-16 are all open, and a diode 16 is provided in series with the temperature sensor 14 on each electrode unit 12, the remaining temperature sensors 14 in the second row will not affect the resistance value of the temperature sensor 14 of the electrode unit 12-6. Therefore, only the temperature sensor 14 of the electrode unit 12-6 operates effectively on the first detection channel A of this group of analog-to-digital converters 23. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature sensor 14 of the electrode unit 12-6. Similarly, the voltage value collected by the second detection channel B in this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-7. The voltage value collected by the third detection channel C in this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-8. The voltage value collected by the fourth detection channel D in this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-9. The voltage value collected by the fifth detection channel E in this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-10.
[0102] When the third grounding switch 25-3 is closed, the first grounding switch 25-1, the second grounding switch 25-2 and the fourth grounding switch 25-4 are all open, and the first bidirectional switch 26-1, the second bidirectional switch 26-2, the third bidirectional switch 26-3, the fourth bidirectional switch 26-4 and the fifth bidirectional switch 26-5 are all switched to their respective acquisition ends 1, the temperature sensors 14 of the electrode units 12-11 to 12-15 in the third row group are powered on, and the temperature sensors 14 of the electrode units 12-1 to 12-10 and the electrode units 12-16 to 12-20 in the remaining row groups are powered off. The signal terminals 14-2 of the temperature sensors 14 of the electrode units 12-1, 12-6, 12-11 and 12-16 are short-circuited by the first detection channel A in this group of analog-to-digital converters 23. Since only the grounding terminal 14-1 of the temperature sensor 14 of the electrode unit 12-11 is conductively grounded, and the grounding terminals 14-1 of the temperature sensors 14 of the electrode units 12-1, 12-6 and 12-16 are all open, and a diode 16 in series with the temperature sensor 14 is provided on each electrode unit 12, the remaining temperature sensors 14 in the third row will not affect the resistance value of the temperature sensor 14 of the electrode unit 12-11. Therefore, only the temperature sensor 14 of the electrode unit 12-11 operates effectively on the first detection channel A of this group of analog-to-digital converters 23. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature sensor 14 of the electrode unit 12-11. Similarly, the voltage value collected by the second detection channel B in this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-12. The voltage value collected by the third detection channel C in this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-13. The voltage value collected by the fourth detection channel D in this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-14. The voltage value collected by the fifth detection channel E in this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-15.
[0103] When the fourth grounding switch 25-4 is closed, the first grounding switch 25-1, the second grounding switch 25-2 and the third grounding switch 25-3 are all open, and the first bidirectional switch 26-1, the second bidirectional switch 26-2, the third bidirectional switch 26-3, the fourth bidirectional switch 26-4 and the fifth bidirectional switch 26-5 are all switched to their respective acquisition ends 1, the temperature sensors 14 of the electrode units 12-16 to 12-20 of the fourth row group are powered on, and the temperature sensors 14 of the electrode units 12-1 to 12-15 of the remaining row groups are powered off. In the first detection channel A of this group of analog-to-digital converters 23, the signal terminals 14-2 of the temperature sensors 14 of the electrode unit 12-1, the electrode unit 12-6, the electrode unit 12-11, and the electrode unit 12-16 are short-circuited. Since only the grounding terminal 14-1 of the temperature sensor 14 of the electrode unit 12-16 is conductively grounded, and the grounding terminals 14-1 of the temperature sensors 14 of the electrode unit 12-1, the electrode unit 12-6, and the electrode unit 12-11 are all open, and a diode 16 is provided in series with the temperature sensor 14 on each electrode unit 12, the remaining temperature sensors 14 in the fourth row do not affect the resistance value of the temperature sensor 14 of the electrode unit 12-16. Therefore, only the temperature sensor 14 of the electrode unit 12-16 operates effectively on the first detection channel A of this group of analog-to-digital converters 23. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature sensor 14 of the electrode unit 12-16. Similarly, the voltage value collected on the second detection channel B of this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-17. The voltage value collected on the third detection channel C of this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-18. The voltage value collected on the fourth detection channel D of this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-19. The voltage value collected on the fifth detection channel E of this group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-20. Thus, the first controller 22 of the adapter 20 or the second controller 32 of the electric field generator 30 can collect the temperature detection signals of the temperature sensors 14 of all the electrode units 12 of a certain electrode plate 10 by controlling a group of bidirectional switches 26 and a group of grounding switches 25 that are all electrically connected to the electrode plate 10. Similarly, the temperature detection signals of the temperature sensors 14 of the electrode units 12 of other electrode plates 10 can be obtained.
[0104] The first controller 22, multiple groups of analog-to-digital converters 23, and multiple groups of bidirectional switches 26 can automatically perform operations through pre-programmed program codes. For example, the first controller 22 first controls all the bidirectional switches 26 in the corresponding group of bidirectional switches 26 to switch to the acquisition end 1, so that the acquisition ends 1 of these bidirectional switches 26 are all turned on and the input ends 2 are all turned off, so that the respective dual-purpose signal lines 19 of the corresponding electrode plates 10 are electrically connected to the corresponding group of analog-to-digital converters 23. Then, the first grounding switch 25-1 in the corresponding group of grounding switches 25 is closed, and the remaining second grounding switch 25-2, third grounding switch 25-3, and fourth grounding switch 25-4 in this group of grounding switches 25 are opened. During this period, each detection channel A, B, C, D, E of the group of analog-to-digital converters 23 obtains the temperature detection signals of the respective temperature sensors 14 of the electrode units 12 located in the first row group in the corresponding electrode plate 10, converts them into digital signals, and stores them in a separately provided memory. Then, after a preset time interval, the first controller 22 closes the second grounding switch 25-2 in this group of grounding switches 25, and opens the first grounding switch 25-1, third grounding switch 25-3, and fourth grounding switch 25-4 in this group of grounding switches 25. During this period, each detection channel A, B, C, D, E of the group of analog-to-digital converters 23 obtains the temperature detection signals of the respective temperature sensors 14 of the electrode units 12 located in the second row group. By sequentially and separately turning on each grounding switch 25 in this group of grounding switches 25 in this way, the temperature detection signals of all the temperature sensors 14 in each row group of the electrode plate 10 can be obtained. Similarly, the temperature detection signals of all the temperature sensors 14 on at least a pair of electrode plates 10 are obtained through this kind of operation.
[0105] The tumor electro-field therapy system 100 of the present application can achieve real-time and comprehensive monitoring of the temperatures of all electrode units 12 on the electrode patch 10 without increasing the weight of the electrode patch 10 and without increasing the cores of the first cables 13 electrically connected to the electrode patch 10. Furthermore, it can judge whether the electrode patch 10 is qualified based on the obtained temperature detection signals; or it can judge whether there are faults or abnormalities in the temperature sensors 14 of the electrode patch 10 based on the obtained temperature detection signals, and judge whether it is necessary to replace the electrode patch 10 based on the number of temperature sensors 14 with faults or abnormalities; or it can identify the type of the electrode patch based on the obtained temperature detection signals when the electrode patch is qualified; or it can judge whether there is an over-temperature situation in the electrode units 12 of the electrode patch 10 based on the obtained temperature detection signals when the electrode patch is qualified, and then control the alternating electric signals applied to the electrode patch 10 or the corresponding column electrode units 12 of the electrode patch 10 to avoid low-temperature burns on the patient's body surface during tumor treatment through the electrode patch 10. In addition, the flexible circuit board 11 of the electrode patch 10 of the present application electrically connects the dielectric element 15 of the same electrode unit 12 and the signal terminal 14-2 of the temperature sensor 14 through the same dual-purpose signal line 19 arranged thereon. While it can transmit both alternating current signals and direct current signals for temperature signal acquisition and the acquired temperature detection signals through the dual-purpose signal line 19, it also greatly reduces the number of conductive traces (ground wire 18, dual-purpose signal line 19) arranged thereon, reduces the wiring difficulty of the flexible circuit board 11, simplifies the manufacturing process, also reduces the weight of the flexible circuit board 11, and reduces the manufacturing cost. The electrode patch 10 of the present application can also be switched between applying alternating current signals for tumor treatment and transmitting direct current signals for temperature acquisition and transmitting the acquired temperature detection signals through the combined control of a ground switch 25 electrically connected to the ground wire 18 arranged thereon and a bidirectional switch 26 electrically connected to the dual-purpose signal line 19.
[0106] When an alternating current signal needs to be applied to a patient through each electrode unit 12 of a certain electrode patch 10, the first controller 22 of the adapter 20 or the second controller 32 of the electric field generator 30 controls all the grounding switches 25 in a group of grounding switches 25 corresponding to the electrode patch 10 to be disconnected, and at the same time controls all the bidirectional switching switches 26 in a group of bidirectional switching switches 26 corresponding to the electrode patch 10 to be switched to their respective input terminals 2, so that the acquisition terminals 1 of these bidirectional switching switches 26 are all disconnected and the input terminals 2 are all conducted, realizing that each two-way signal line 19 of the electrode patch 10 is electrically connected to an AC signal line 28 corresponding to the adapter 20 and the electrode patch 10, thereby transmitting the alternating current signal to each electrode unit 12 of the electrode patch 10.When the temperature detection signals of the temperature sensors 14 of all the electrode units 12 of the detected electrode patch 10 are much lower than the preset temperature threshold stored in the electric field generator 30 or the adapter 20, the electric field generator 30 controls the AC signal generator 34 through its second controller 32 to continue generating an alternating current signal with an increasing voltage or current amplitude or a constant voltage or current amplitude, and then transmits it to the corresponding pair of electrode patches 10 through a corresponding AC signal line 28 of the adapter 20, so as to continue applying the alternating current signal to the pair of electrode patches 10; when the temperature detection signals of the temperature sensors 14 of all the electrode units 12 of the detected electrode patch 10 are lower than but close to the preset temperature threshold stored in the electric field generator 30 or the adapter 20, the electric field generator 30 can reduce the voltage or current of the alternating current signal generated by the AC signal generator 34 through the second controller 32, and then reduce the voltage or current of the alternating current signal applied to the pair of electrode patches 10; when the temperature detection signal of the temperature sensor 14 of an electrode unit 12 of a certain electrode patch 10 is detected to be greater than the preset temperature threshold, the electric field generator 30 controls the AC signal switch 35 electrically connected to the electrode patch 10 to be turned off through the second controller 32 to stop applying the alternating current signal to the electrode patch 10; or the second controller 32 of the electric field generator 30 or the first controller 22 of the adapter 20 controls all the bidirectional switches 26 in a group of bidirectional switches 26 electrically connected to the electrode patch 10 to switch from their input terminals 2 to the acquisition terminals 1, that is, controls all the acquisition terminals 1 of all the bidirectional switches 26 in a group of bidirectional switches 26 electrically connected to the electrode patch 10 to be turned on and all the input terminals 2 to be turned off, so as to stop applying the alternating current signal to the electrode patch 10; or, when the temperature detection signal of the temperature sensor 14 of an electrode unit 12 of a certain electrode patch 10 is detected to be greater than the preset temperature threshold, the second controller 32 of the electric field generator 30 controls the AC signal switch 35 electrically connected to the electrode patch 10 to continue to be turned on, and the second controller 32 of the electric field generator 30 or the first controller 22 of the adapter 20 controls a bidirectional switch 26 electrically connected to the electrode unit 12 of the electrode patch 10 to switch from its input terminal 2 to its acquisition terminal 1, and at the same time, the second controller 32 of the electric field generator 30 or the first controller 22 of the adapter 20 controls the remaining bidirectional switches 26 electrically connected to the electrode units 12 whose temperature detection signals do not exceed the preset temperature threshold and are in different columns from the electrode units 12 whose temperature detection signals exceed the preset temperature threshold of the electrode patch 10 to keep their input terminals 2 electrically connected respectively, so as to stop applying the alternating current signal to all the electrode units 12 in the column where the electrode unit 12 with the temperature detection signal exceeding the preset temperature threshold of the electrode patch 10 is located, and continue to apply the alternating current signal to the remaining column electrode units 12 of the electrode patch 10 whose temperature detection signals do not exceed the preset temperature threshold. Thus, a control method for the regional application of the alternating current signal of the tumor electric field treatment system 100 based on the temperature detection signal is realized.When applying an alternating current signal, all the grounding switches 25 are opened.
[0107] In the embodiment of the present application, the grounding switches 25 respectively and electrically connected to the multiple ground wires 18 of the electrode sheet 10 one by one, and the bidirectional switching switches 26 respectively and electrically connected to the multiple dual-purpose signal lines 19 of the electrode sheet 10 one by one are all arranged in the adapter 20. However, in other embodiments, the grounding switches 25 electrically connected to the ground wires 18 and the bidirectional switching switches 26 electrically connected to the dual-purpose signal lines 19 can also be arranged on the electrode sheet 10 or in the electric field generator 30, which will not be elaborated here. In addition, the analog-to-digital converter 23 arranged in the adapter 20 can also be arranged in the electric field generator 30 and directly controlled by the second controller 32.
[0108] The present application also provides other embodiments of the electrode sheet 10. The differences among the multiple embodiments are mainly the differences in the number of the electrode units 12 and / or the different electrical connection arrangement modes of the electrode units 12, which will be described separately below.
[0109] Reference Figure 6As shown, the electrode sheet 10A of the second embodiment is provided with 19 electrode units 12.

The electrode sheet 10A includes 4 ground wires 18 and 5 dual-purpose signal lines 19. Each ground wire 18 is used to ground the ground terminals 14-1 of the temperature sensors 14 of the electrode units 12 in the same row group. Each dual-purpose signal line 19 shorts the dielectric elements 15 of the electrode units 12 in each column group and the signal terminals 14-2 of the temperature sensors 14 respectively, and is used to receive temperature detection signals or transmit alternating current signals.

The working mode of the tumor electric field treatment system formed by the electrode plate 10A, the adapter 20, and the electric field generator 30 is the same as that of the aforementioned tumor electric field treatment system 100. When all the grounding switches 25 are all disconnected and the input ends 2 of all the bidirectional switching switches 26 are conducting and the acquisition ends 1 are disconnected, all the dual-purpose signal wires 19 are conducting with the AC signal wire 28, and all the electrode units 12 are connected to the AC signal; when the acquisition ends 1 of all the bidirectional switching switches 26 are conducting and the input ends 2 are disconnected, by sequentially conducting each grounding switch 25, the temperature detection signals of the temperature sensors 14 of each electrode unit 12 in each row group can be obtained in sequence.

Each ground wire 18 is used to ground the ground terminals 14-1 of the temperature sensors 14 of the electrode units 12 in the same row group. Each dual-purpose signal line 19 shorts the dielectric elements 15 of the electrode units 12 in each column group and the signal terminals 14-2 of the temperature sensors 14 respectively, and is used to receive temperature detection signals or transmit alternating current signals.

When the acquisition ends 1 of all the bidirectional switching switches 26 are turned on and the input ends 2 are disconnected, the grounding switches 25 are sequentially turned on to sequentially obtain the temperature detection signals of the temperature sensors 14 of each electrode unit 12 in each row group. Among them, no operation is required for the grounding switches 25 in the idle disconnected state.

[0146] The working mode of the tumor electric field treatment system formed by the electrode sheet 10J, the adapter 20, and the electric field generator 30 is the same as that of the aforementioned tumor electric field treatment system 100. When all ground switches 25 are disconnected and the input ends 2 of all bidirectional switches 26 are turned on and the acquisition ends 1 are disconnected, all dual-purpose signal lines 19 are turned on to the AC signal line 28, and all electrode units 12 are connected to the AC signal; when the acquisition ends 1 of all bidirectional switches 26 are turned on and the input ends 2 are disconnected, by sequentially turning on the respective ground switches 25, the temperature detection signals of the temperature sensors 14 of the respective electrode units 12 in each row group can be obtained in sequence. Among them, no operation is required for the ground switch 25 in the idle open state and the bidirectional switch 26 in the idle open state.
[0147] In the tumor electro-field therapy system of the present application, the flexible circuit boards (11, 11A, 11B, 11C, 11D, 11E, 11F, 11G, 11H, 11J) of each electrode plate (10, 10A, 10B, 10C, 10D, 10D’, 10D”, 10E, 10F, 10G, 10H, 10J) electrically connect their electrode units 12 into multiple rows and columns. And the grounding ends 14-1 of the temperature sensors 14 of the electrode units 12 in the same row are electrically connected to the same ground wire 18. After the dielectric elements 15 of the electrode units 12 in the same column and the signal ends 14-2 of their respective temperature sensors 14 are short-circuited, they are electrically connected to the same dual-purpose signal wire 19. The adapter 20 is provided with a plurality of grounding switches 25 and a plurality of bidirectional switching switches 26. The respective ground wires 18 of the electrode plates (10, 10A, 10B, 10C, 10D, 10D’, 10D”, 10E, 10F, 10G, 10H, 10J) are respectively and electrically connected to the corresponding grounding switches 25 one by one, and the respective dual-purpose signal wires 19 are respectively and electrically connected to the corresponding bidirectional switching switches 26 one by one. Among them, the number of grounding switches 25 is greater than or equal to the number of ground wires 18, and the number of bidirectional switching switches 26 is greater than or equal to the number of dual-purpose signal wires 19.

However, in some usage cases, there will be grounding switches 25 in an idle and disconnected state and / or bidirectional switching switches 26 in an idle and disconnected state, and the program control will be relatively complex. Another way is to provide a specific adapter for the number of ground wires 18 and the number of dual-purpose signal wires 19 of the electrode plate to avoid the occurrence of grounding switches 25 in an idle and disconnected state and / or bidirectional switching switches 26 in an idle and disconnected state, which is convenient for program control.

Refer to Figure 31 , the working mode of the tumor electric field treatment system formed by the electrode plate 10H, the adapter 20D and the electric field generator 30 is the same as that of the aforementioned tumor electric field treatment system 100. When all the grounding switches 25 are disconnected and the input ends 2 of all the bidirectional switching switches 26 are conducted and the acquisition ends 1 are disconnected, all the dual-purpose signal wires 19 are conducted with the AC signal wire 28, and all the electrode units 12 are connected to the AC signal; when the acquisition ends 1 of all the bidirectional switching switches 26 are conducted and the input ends 2 are disconnected, by sequentially conducting each grounding switch 25, the temperature detection signals of the temperature sensors 14 of each electrode unit 12 in each row group can be obtained in sequence.
[0171] Refer to Figure 32As shown, an adapter 20E of the seventh embodiment adapted to the electrode sheet 10J of the foregoing tenth embodiment is provided. The adapter 20E also includes: a first controller 22, multiple groups of analog-to-digital converters 23 connected to the first controller 22, multiple groups of voltage dividing resistors 24 and multiple groups of grounding switches 25 corresponding to the multiple groups of analog-to-digital converters 23 one by one, multiple groups of bidirectional switching switches 26 connected to the multiple groups of analog-to-digital converters 23 one by one, a first communication unit 27, AC signal lines 28 connected to each group of bidirectional switching switches 26 one by one, and a first power module 29 connected to the first communication unit 27, the first controller 22, and the multiple groups of analog-to-digital converters 23 at the same time. The first power module 29 provides a DC power supply VCC for each electronic component of the adapter 20E. The adapter 20E also includes multiple circuit lines (not labeled) therein. The difference between it and the foregoing adapter 20 is that: each group of grounding switches 25 of the adapter 20E reduces the setting of a fourth grounding switch 25-4, each group of bidirectional switching switches 26 reduces the setting of a fifth bidirectional switching switch 26-5 and a fourth bidirectional switching switch 26-4, and reduces the settings of the detection channels E and D corresponding to the fifth bidirectional switching switch 26-5 and the fourth bidirectional switching switch 26-4 in each group of analog-to-digital converters 23, as well as reduces the settings of the voltage dividing resistors corresponding to the fifth bidirectional switching switch 26-5 and the fourth bidirectional switching switch 26-4 in each group of voltage dividing resistors 24. For the other specific structures and working principles of the adapter 20E, please refer to the relevant specific descriptions of the foregoing adapter 20, which will not be elaborated here.
[0172] The first grounding switch 25-1, the second grounding switch 25-2, and the third grounding switch 25-3 on the adapter 20E are respectively and electrically connected to the first grounding wire 18-1, the second grounding wire 18-2, and the third grounding wire 18-3 one by one through the first connector 40J'.

Refer to Figure 33 , the working mode of the tumor electric field treatment system formed by the electrode sheet 10J, the adapter 20E, and the electric field generator 30 is the same as that of the foregoing tumor electric field treatment system 100. When all the grounding switches 25 are disconnected and the input ends 2 of all the bidirectional switching switches 26 are conducting and the acquisition ends 1 are disconnected, all the dual-purpose signal wires 19 are conducting with the AC signal lines 28, and all the electrode units 12 are connected to the AC signal; when the acquisition ends 1 of all the bidirectional switching switches 26 are conducting and the input ends 2 are disconnected, by sequentially conducting each grounding switch 25, the temperature detection signals of the temperature sensors 14 of each electrode unit 12 in each row group can be obtained in sequence.
[0173] The present application also provides some temperature detection methods and AC signal application control methods, which will be described below by taking the electrode patch 10 as an example.
[0174] An embodiment of the present application provides an electrode patch temperature detection method, which is applied to the above-mentioned electrode patch 10 or the tumor electric field treatment system 100. Refer Figure 34 as shown, it includes the following steps:
[0175] Step 210: Control each bidirectional switching switch 26 electrically connected to each electrode unit 12 of the electrode patch 10 to disconnect the AC signal applied to the dielectric element 15 of each electrode unit 12 of the electrode patch 10, and at the same time connect the DC signal applied to the signal terminal 14-2 of the temperature sensor 14 of each electrode unit 12 of the electrode patch 10;
[0176] Step 220: Sequentially turn on each grounding switch 25 electrically connected to the grounding terminal 14-1 of the temperature sensor 14 of each electrode unit 12 of the electrode patch 10 in time sequence to obtain the temperature detection signal of the temperature sensor 14 of each electrode unit 12 of the electrode patch 10.
[0177] Step 210 is specifically: Control the bidirectional switching switch 26 electrically connected to each electrode unit 12 of the electrode patch 10 to switch from the end electrically connected to the AC signal to the end electrically connected to the DC signal, that is, control the bidirectional switching switch 26 electrically connected to the electrode patch 10 to switch from its input terminal 2 to its acquisition terminal 1; or
[0178] Control the bidirectional switching switch 26 electrically connected to each electrode unit 12 of the electrode patch 10 to switch the dielectric element 15 of each electrode unit 12 of the electrode patch 10 from the conducting state to the disconnected state, and at the same time switch the signal terminal 14-2 of the temperature sensor 14 of each electrode unit 12 of the electrode patch 10 from the disconnected state to the conducting state.
[0179] By using the electrode patch temperature detection method of the present application, the temperatures of all electrode units of the electrode patch can be obtained quickly and accurately; and it is possible to judge whether there is a fault, whether there is an abnormality, whether the electrode patch is qualified, or whether it needs to be replaced based on the temperature detection signals of all the temperature sensors of the obtained electrode patch; it is also possible to judge whether there is overheating in each electrode unit of the electrode patch based on the temperature detection signals of all the temperature sensors of the obtained electrode patch when the temperature sensors of the electrode patch are normal, and then control the AC signal applied to the electrode patch or each electrode unit of the electrode patch; it is also possible to identify the type of the electrode patch when the temperature detection signals of the temperature sensors of the electrode patch are normal.
[0180] Refer Figure 35As shown, the embodiment of the present application further provides an alternating current signal application control method for tumor electric field therapy, which includes the above steps 210 and 220, and after step 220, it further includes:
[0181] Step 260: When it is determined that the electrode patch 10 does not need to be replaced, control or adjust the alternating current signal applied to each electrode unit 12 of the electrode patch 10 according to the temperature detection signals of the temperature sensors 14 of each electrode unit 12 of the electrode patch 10 obtained.
[0182] The control or adjustment of the alternating current signal applied to each electrode unit 12 of the electrode patch 10 in step 260 further includes:
[0183] Step 261: When the temperature detection signals of each electrode unit 12 of the electrode patch 10 obtained do not exceed the preset temperature threshold, continue to apply the alternating current signal to each electrode unit 12 of the electrode patch 10; or
[0184] Step 262: When there is a temperature detection signal exceeding the preset temperature threshold among the temperature detection signals of all electrode units 12 of the electrode patch 10 obtained, stop applying the alternating current signal to the electrode units 12 of the electrode patch 10.
[0185] The stopping of applying the alternating current signal to the electrode units 12 of the electrode patch 10 in step 262 includes stopping applying the alternating current signal to all electrode units 12 of the electrode patch 10, stopping applying the alternating current signal to the electrode units 12 of the electrode patch 10 where the temperature detection signals exceed the preset temperature threshold, and stopping applying the alternating current signal to all electrode units 12 in the column where the electrode units 12 of the electrode patch 10 with temperature detection signals exceeding the preset temperature threshold are located.
[0186] When stopping applying the alternating current signal to the electrode units 12 of the electrode patch 10 where the temperature detection signals exceed the preset temperature threshold, the electrode units 12 of the electrode patch 10 where the temperature detection signals do not exceed the preset temperature threshold continue to be applied with the alternating current signal.
[0187] When stopping applying the alternating current signal to all electrode units 12 in the column where the electrode units 12 of the electrode patch 10 with temperature detection signals exceeding the preset temperature threshold are located, the electrode units 12 of the electrode patch 10 where the temperature detection signals do not exceed the preset temperature threshold and are in different columns from the electrode units 12 with temperature detection signals exceeding the preset temperature threshold continue to be applied with the alternating current signal.
[0188] The process of continuing to apply the alternating current signal to the electrode patch 10 in step 261 is specifically:
[0189] Step 263: When the temperature detection signal is much lower than the preset temperature threshold, continue to apply an alternating current signal to each electrode unit 12 of the electrode sheet 10 by increasing the voltage or current amplitude of the alternating current signal applied to each electrode unit 12 of the electrode sheet 10 or continue to apply an alternating current signal to each electrode unit 12 of the electrode sheet 10 in a manner that keeps the voltage or current amplitude of the alternating current signal applied to each electrode unit 12 of the electrode sheet 10 unchanged; or
[0190] Step 264: When the temperature detection signal is close to the preset temperature threshold, continue to apply an alternating current signal to each electrode unit 12 of the electrode sheet 10 in a manner that keeps the voltage or current amplitude of the alternating current signal applied to each electrode unit 12 of the electrode sheet 10 unchanged or continue to apply an alternating current signal to each electrode unit 12 of the electrode sheet 10 by reducing the voltage or current amplitude of the alternating current signal applied to each electrode unit 12 of the electrode sheet 10.
[0191] See Figure 36 As shown, the present application also provides a signal control method for tumor electric field therapy for the above-mentioned electrode sheet 10, and the method includes:
[0192] Step 310: Combine and control the ground switch 25 and the bidirectional switch 26 electrically connected to the corresponding electrode sheet 10 to apply an alternating current signal to each electrode unit 12 of the electrode sheet 10 and execute Step 320;
[0193] Step 320: Combine and control the ground switch 25 and the bidirectional switch 26 electrically connected to the electrode sheet 10 to collect the temperature detection signals of each electrode unit of the electrode sheet 10 in a row and execute Step 330;
[0194] Step 330: Determine the combined control mode of the ground switch 25 and the bidirectional switch 26 electrically connected to the electrode sheet 10 according to the collected temperature detection signals and execute Step 340;
[0195] Step 340: Control the working states of each electrode unit 12 of the electrode sheet 10 according to the determined combined control mode of the ground switch 25 and the bidirectional switch 26.
[0196] The working states of each electrode unit 12 of the electrode sheet 10 described in Step 340 include: stopping applying the alternating current signal and continuing to collect the temperature detection signals and stopping collecting the temperature detection signals and continuing to apply the alternating current signal. Continuing to apply the alternating current signal includes continuing to apply the alternating current signal by increasing the voltage or current amplitude of the currently applied alternating current signal, continuing to apply the alternating current signal in a manner that keeps the voltage or current amplitude of the currently applied alternating current signal unchanged, and continuing to apply the alternating current signal by reducing the voltage or current amplitude of the currently applied alternating current signal.
[0197] The operating state of each electrode unit 12 of the electrode sheet 10 is determined by the temperature detection signal collected thereby. Each electrode unit 12 of the electrode sheet 10 is divided into different regions, and through the combination control of the grounding switches 25 and the bidirectional switching switches 26, each electrode unit 12 in each region can be cyclically switched between applying an alternating current signal and collecting a temperature detection signal.
[0198] Another electrode sheet temperature detection method for the tumor electric field therapy system 100 is provided in an embodiment of the present application. Please refer to Figure 37 as shown, this temperature detection method includes:
[0199] Step 510: Disconnect the input of the alternating current signal of the electrode sheet 10, perform combined control on a plurality of grounding switches 25 and a plurality of bidirectional switching switches 26, and obtain the temperature detection signals of the temperature sensors 14 of the electrode sheet 10 corresponding to each combination in all combinations;
[0200] Step 520: Sample and convert the temperature detection signals detected by each temperature sensor 14 in the electrode sheet 10 to obtain digital temperature signals;
[0201] Step 530: Transmit the digital temperature signals to the electric field generator 30 of the tumor electric field therapy system 100, so that the electric field generator 30 determines the temperature at the corresponding electrode unit 12 according to the digital temperature signals.
[0202] In step 510, "performing combined control on a plurality of grounding switches 25 and a plurality of bidirectional switching switches 26" specifically includes:
[0203] Step 511: Place all the bidirectional switching switches 26 at the acquisition end 1 to conduct the electrical connection between the signal ends 14-2 of the temperature sensors 14 of all electrode units 12 and the corresponding analog-to-digital converters 23;
[0204] Step 512: Sequentially and separately close one of the plurality of grounding switches 25 to sequentially collect the temperature detection signals detected by the temperature sensors 14 of the electrode units 12 in the corresponding row groups.
[0205] Sequentially and separately closing one of the plurality of grounding switches 25 in step 512 can conduct the detection channels in which the analog-to-digital converter 23 is electrically connected to all the temperature sensors 14 in the row group corresponding to the closed grounding switch 25.
[0206] Thus, the temperature detection signals of the corresponding temperature sensors 14 in each row group can be sequentially obtained, and then through the processing of the adapter 20 or the electric field generator 30, the temperatures corresponding to all the electrode units 12 on the electrode sheet 10 can be obtained; thereby making the temperature detection on the patient's body surface more comprehensive and accurate.
[0207] For the tumor electric field therapy system 100 according to the embodiments of the present application, the temperature of a single electrode unit 12 can also be detected as needed. The specific process of detecting the temperature of a certain electrode unit 12 of the electrode sheet 10 is as follows: disconnect the input of the alternating current signal, place the bidirectional switching switch 26 corresponding to the column group where the electrode unit 12 to be individually temperature-measured is located at the acquisition end 1, and place the remaining bidirectional switching switches 26 at the input end 2; at the same time, turn on and ground the grounding switch 25 corresponding to the row group where the electrode unit 12 to be individually temperature-measured is located, and disconnect all the remaining grounding switches 25. Thus, the temperature detection signal of the temperature sensor 14 in the electrode unit 12 to be individually temperature-measured can be sampled to obtain the temperature of the electrode unit 12. For example, if the electrode unit 12 to be individually temperature-measured is the electrode unit 12-1, at this time, disconnect the corresponding AC signal switch 35 of the electric field generator 30, place the first bidirectional switching switch 26-1 corresponding to the electrode unit 12-1 at the acquisition end 1, and place all the remaining other bidirectional switching switches (the second bidirectional switching switch 26-2, the second bidirectional switching switch 26-3, the third bidirectional switching switch 26-3, and the fourth bidirectional switching switch 26-4) at the input end 2; at the same time, close and ground the first grounding switch 25-1 corresponding to the electrode unit 12-1, and disconnect all the remaining grounding switches (the second grounding switch 25-2, the third grounding switch 25-3, and the fourth grounding switch 25-4). Thus, the temperature of the electrode unit 12-1 can be detected.
[0208] The embodiments of the present application also provide another method for applying an alternating current signal for tumor electric field therapy, which is applied to the above-mentioned tumor electric field therapy system 100.

[0215] In step 610: Divide every adjacent 4 electrode units 12 in the electrode sheet 10 into one area, the 4 electrode units 12 in each area correspond to one column group, and are connected to a two-way signal line 19 corresponding to the same bidirectional switching switch 26.
[0216] Step 615: Control the bidirectional switching switches 26 electrically connected to the electrode units 12 that need to be applied with AC signal to electrically connect the electrode units 12 that need to be applied with AC signal to the AC signal line 28 to apply AC signal; at the same time, control the remaining bidirectional switching switches 26 to disconnect the electrical connection between each electrode unit 12 in the area where no AC signal needs to be applied and the AC signal line 28 to stop applying AC signal.
[0217] In step 615, "electrically connect the electrode units that need to be applied with AC signal to the AC signal line 28 to apply AC signal and disconnect the electrical connection between the electrode units 12 in the area where no AC signal needs to be applied and the AC signal line 28 to stop applying AC signal" is achieved by placing the bidirectional switching switches 26 electrically connected to the electrode units 12 in the column groups corresponding to the area where AC signal needs to be applied in the electrode sheet 10 at their input terminals 2, and placing all the bidirectional switching switches 26 electrically connected to the electrode units 12 in the remaining column groups at the acquisition terminals 1.
