Description

Electrode sheet, tumor electric field therapy system, detection method and signal control method Technical Field

[0001] The present application relates to Tumor Treating Fields (TTF) technology, and in particular to an electrode sheet, a tumor treating field system, a detection method, and a signal control method. Background Art

[0002] Tumor electric field therapy is a method that uses low-intensity, medium- and high-frequency alternating electric fields to prevent the formation of spindle microtubules during mitosis in certain tumor cells, thereby inhibiting the separation of intracellular organelles during cell division and inducing cell apoptosis during mitosis, thereby achieving the purpose of treating tumors.

[0003] Compared with traditional cancer treatments, TTF has an innovative mechanism of action. Some physiological characteristics of tumor cells, such as geometric shape and high-frequency mitosis, make them susceptible to TTF. TTF disrupts the normal aggregation of tubulin by exerting directional forces on polar particles (such as macromolecules and organelles) in cells. These processes may lead to physical damage to the cell membrane and cell apoptosis. At the end of cell mitosis, the structural morphology of the cleavage furrow will lead to uneven distribution of the electric field around it. At the same time, under the influence of TTF, the electric field intensity at the cleavage furrow is significantly enhanced, and the charged substances in the cell move toward the cleavage furrow, which interferes with or even destroys the formation of the cell structure, and ultimately leads to cell division failure and apoptosis.

[0004] In existing tumor electric field therapy systems, an electric field generator is used to transmit the alternating current signal for tumor electric field therapy to the electrodes, which then apply an alternating electric field to the patient's tumor site for tumor electric field therapy. When the tumor therapy electric field is applied to the patient's body, heat accumulates at the electrode application site, and the temperature of the electrode application site also rises accordingly. Therefore, it is necessary to constantly monitor the temperature of the electrode application site. When the monitored temperature rises to a certain preset value, it is necessary to promptly adjust the electric field strength applied to the patient's tumor site to avoid excessive temperature at the electrode application site, which may cause burns to the patient's skin.

[0005] The tumor electric field therapy system includes at least one pair of electrode sheets, each of which contains multiple electrode units. Even if the same alternating current signal is applied to each electrode unit, the heat generated by each electrode unit will vary due to its different location, that is, the temperature of each electrode unit on the entire electrode sheet will not be completely consistent. This may result in the temperature of some electrode units in the entire electrode sheet exceeding the preset temperature, while the temperature of other electrode units is normal. In order to ensure that the tumor electric field therapy has a sufficiently long application time while avoiding low-temperature burns on the patient's body surface, it is necessary to implement individual control of the overheated electrode units. However, for existing electrode sheets, implementing individual control of the electrode units requires providing a conductive trace for each electrode unit in the substrate of the electrode sheet. This will increase the number of conductive traces in the electrode sheet substrate, making the electrode sheet less likely to bend, and the cable electrically connected to the electrode sheet will also be thickened, which increases the overall weight of the electrode sheet, making it difficult to apply the electrode sheet.

[0006] Therefore, it is necessary to provide an electrode sheet, a tumor electric field therapy system, a detection method, and a signal control method that use fewer conductive traces to perform partitioned control on multiple electrode units. Summary of the Invention

[0007] The first purpose of this application is to provide a tumor electric field therapy system and an electrode sheet to solve or eliminate the problems in the related art.

[0008] The second object of the present application is to provide a method for detecting the temperature of an electrode.

[0009] The third object of the present application is to provide a signal control method for tumor electric field therapy.

[0010] To achieve the above-mentioned purpose, the present application provides the following technical solutions: an electrode sheet for tumor electric field therapy, comprising: a plurality of electrode units, wherein the plurality of electrode units are divided into a plurality of row groups and a plurality of column groups in terms of circuit connection; and a flexible circuit board, configured for the plurality of electrode units to be arranged at intervals thereon, wherein a plurality of conductive traces are embedded in the flexible circuit board, wherein the plurality of conductive traces include: a plurality of grounding wires, corresponding one-to-one to the plurality of row groups, each of the grounding wires being configured to short-circuit corresponding parts of each electrode unit in the corresponding row group to ground; and a plurality of dual-purpose signal lines, corresponding one-to-one to the plurality of column groups, each of the dual-purpose signal lines being configured to transmit an alternating current signal to each electrode unit in the corresponding column group in a first mode, and to transmit a direct current signal or a temperature detection signal detected by each electrode unit in the corresponding column group in a second mode.

[0011] According to the tumor electric field therapy system of the present application, the flexible circuit board of its electrode sheet is provided with multiple dual-purpose signal lines, which can transmit AC signals in the first mode and transmit DC signals or collect temperature detection signals of each electrode unit in the second mode. There is no need to set up separate conductive traces for transmitting AC signals only, which can reduce the number of wire cores of the wires connecting the electrode sheet and the adapter.

[0012] To achieve the above-mentioned purpose, the present application also provides the following technical solution: a method for detecting electrode sheet temperature, applied to the above-mentioned electrode sheet or to the above-mentioned tumor electric field therapy system, the method comprising the following steps: turning on all the multiplexed signal lines corresponding one-to-one to the multiple column groups of the corresponding electrode sheet to collect temperature signals; and turning on each of the multiple grounding lines corresponding one-to-one to the multiple row groups of the corresponding electrode sheet in sequence and in a time-sharing manner to collect the temperature detection signals of each electrode unit in each row group of the electrode sheet by row through the multiplexed signal lines.

[0013] To achieve the above-mentioned purpose, the present application also provides the following technical solution: a signal control method for tumor electric field therapy, applied to the above-mentioned electrode sheet or to the above-mentioned tumor electric field therapy system, wherein the signal for tumor electric field therapy is achieved by combining and controlling the conduction and disconnection of multiple dual-purpose signal lines that correspond one-to-one to each column group of the electrode sheet and are electrically connected to the electrode units of each column group, and multiple ground lines that correspond one-to-one to each row group of the electrode sheet and are electrically connected to the electrode units of each row group, so that each electrode unit of the electrode sheet can cyclically switch between applying an alternating current signal and collecting or transmitting a temperature detection signal.

DETAILED DESCRIPTION

[0057] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

[0058] FIG1 is a schematic diagram of a tumor electric field therapy system 100 according to an embodiment of the present application. As shown in FIG1 , the tumor electric field therapy system 100 includes: at least one pair of electrode sheets 10, an adapter 20 electrically connected to the electrode sheets 10, and an electric field generator 30 electrically connected to the adapter 20. The electric field generator 30 generates an alternating current (AC) signal for tumor treatment and applies the AC signal to the electrode sheets 10 via the adapter 20 to generate a therapeutic electric field between the paired electrode sheets 10. The adapter 20 is electrically connected between the electrode sheets 10 and the electric field generator 30 and is used to transmit the AC signal generated by the electric field generator 30 to the electrode sheets 10. In other words, the electric field generator 30 is capable of generating an AC signal, which is transmitted to each electrode sheet 10 via the adapter 20, thereby generating a therapeutic electric field for tumor treatment between the same pair of electrode sheets 10.

[0059] As shown in Figure 1, in this embodiment, the number of electrode sheets 10 is 4. From the perspective of spatial structural arrangement, each electrode sheet 10 includes a plurality of electrode units 12 that are both axially symmetrically arranged and centrally symmetrically arranged and of the same number, a number of connecting portions 111 located between two adjacent electrode units 12, a bridging portion 113 erected between two adjacent connecting portions 111, a wiring portion 112 connected to the bridging portion 113, and a first cable 13 connected to the wiring portion 112. The bridging portion 113 and the wiring portion 112 are arranged vertically to form a "T" shape. The bridging portion 113 is erected between two adjacent connecting portions 111. Each electrode unit 12 of the electrode sheet 10 is electrically connected to the adapter 20 via the first cable 13.

[0060] Each electrode unit 12 has a temperature sensor 14 and a dielectric element 15. The temperature sensor 14 is used to detect the temperature of the part of the patient's body surface to which the electrode unit 12 is applied. It can be a thermistor element or a temperature sensor other than a thermistor, and can be set at any position on the electrode unit 12. The dielectric element 15 is used to apply an AC signal to the patient's tumor site. 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 (unnumbered) provided in the middle for accommodating a corresponding temperature sensor 14. Each electrode unit 12 can also include a diode 16 connected in series with the temperature sensor 14, which can prevent the reverse flow 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.

[0061] In a first mode, the electrode unit 12 applies an AC signal via the dielectric element 15. In a second mode, the temperature sensor 14 detects or collects the temperature of the patient's body surface to which the corresponding electrode unit 12 is applied. In a third mode, the application of the AC signal and temperature detection and collection cease. The first, second, and third modes do not overlap in time periods. That is, the time periods during which the dielectric element 15 of the electrode unit 12 applies the AC signal are staggered and do not overlap with the time periods during which the temperature sensor 14 detects temperature. The electrode unit 12 can cyclically switch between applying the AC signal via its dielectric element 15 and detecting temperature via its temperature sensor 14, that is, the electrode unit 12 can cyclically switch between the first and second modes. The electrode unit 12 can also cyclically switch between the first, second, and third modes, that is, the electrode unit 12 cyclically switches between applying the AC signal via the dielectric element 15, collecting or detecting temperature via the temperature sensor 14, and then cessation of applying the AC signal and collecting temperature.

[0062] Each electrode sheet 10 includes an electrode array (unnumbered) consisting of 20 electrode units 12. The electrode array (unnumbered) also has a flexible circuit board 11 including a connecting portion 111, a wiring portion 112, and a bridging portion 113. The 20 electrode units 12 are distributed in an electrode array (unnumbered) arranged in four rows and six columns. Specifically, the first and last rows each have four electrode units 12, and the middle two rows each have six electrode units 12. The four electrode units 12 in the first row are respectively located in each of the second to fifth columns, the six electrode units 12 in each of the middle two rows are respectively located in each of the first to sixth columns, and the four electrode units 12 in the last row are also respectively located in each of the second to fifth columns.

[0063] The connecting portion 111 is located only between two adjacent electrode units 12 arranged in the column direction in each of the third and fourth columns, and between two adjacent electrode units 12 in the row direction, excluding the two electrode units 12 in the third and fourth columns. That is, the two adjacent electrode units 12 in the third and fourth columns are connected only in the column direction via the connecting portion 111, and are disconnected in the row direction, not connected by the connecting portion 111. The electrode units 12 in each of the first, second, fifth, and sixth columns are connected only to the electrode units 12 adjacent in the row direction via the horizontally arranged connecting portion 111, and are disconnected in the column direction from the electrode units 12 adjacent to them. In other words, the two adjacent electrode units 12 in the first, second, fifth, and sixth columns are disconnected.

[0064] The electrode units 12 in the third column and the longitudinally disposed connecting portions 111 between the electrode units 12 in that column, as well as the electrode units 12 in the fourth column and the longitudinally disposed connecting portions 111 between the electrode units 12 in that column, constitute the backbone 114 of the electrode array (unnumbered). The connecting portions 111 located on opposite sides of the electrode units 12 in the third and fourth columns, connected to the electrode units 12 in the third and fourth columns via the transversely disposed connecting portions 111, and the electrode units 12 connected to the transversely disposed connecting portions 111, constitute the branches 115 of the electrode array (unnumbered). In other words, in this embodiment, the electrode array (unnumbered) includes two backbones 114 and a plurality of branches 115 extending laterally from the two backbones 114. Each branch 115 has a free end distal from the backbone 114. The free ends of adjacent branches 115 are disconnected, and the position and distance between adjacent branches 115 can be freely adjusted according to actual usage scenarios. Specifically, one trunk 114 is composed of the electrode units 12 in the third column and the longitudinally arranged connecting portions 111 between adjacent electrode units 12 in the column. Another trunk 114 is composed of the electrode units 12 in the fourth column and the longitudinally arranged connecting portions 111 between adjacent electrode units 12 in the column. The remaining electrode units 12 connected to the trunk 114 via the transversely arranged connecting portions 111 and the transversely arranged connecting portions 111 are all branches 115.

[0065] Specifically, the branches 115 are: a connecting portion 111 extending laterally to the left from the electrode unit 12 in the first row of the third column and located in the first row, and an electrode unit 12 connected to the connecting portion 111 and located in the second column of the first row; two connecting portions 111 extending laterally to the left from the electrode unit 12 in the second row of the third column and located in the second row, and two electrode units 12 located in the first column of the second row and the second column of the second row; two connecting portions 111 extending laterally to the left from the electrode unit 12 in the third row of the third column and located in the third row, and two electrode units 12 located in the first column of the third row and the second column of the third row; a connecting portion 111 extending laterally to the left from the electrode unit 12 in the fourth row and located in the fourth row, and The electrode unit 12 in the second column of the fourth row; a connecting portion 111 extending laterally to the right from the electrode unit 12 in the first row of the fourth column and located in the first row, and the electrode unit 12 located in the fifth column of the first row; two connecting portions 111 extending laterally to the right from the electrode unit 12 in the second row of the fourth column and located in the second row, and two electrode units 12 located in the fifth column of the second row and the sixth column of the second row; two connecting portions 111 extending laterally to the right from the electrode unit 12 in the third row of the fourth column and located in the third row, and two electrode units 12 located in the fifth column of the third row and the sixth column of the third row; a connecting portion 111 extending laterally to the right from the electrode unit 12 in the fourth row of the fourth column and located in the fourth row, and the electrode unit 12 located in the fifth column of the fourth row.

[0066] The electrode array (unnumbered) is divided into a symmetrical left portion comprising three columns on the left and a right portion comprising three columns on the right, and the left portion and the right portion are connected only by a bridge portion 113. The left portion is composed of a trunk 114 located in the third column and a plurality of branches 115 extending laterally to the left from the trunk 114, and the right portion is composed of a trunk 114 located in the fourth column and a plurality of branches 115 extending laterally to the right from the trunk 114. The two trunks 114 are connected by a bridge portion 113 provided therebetween. Specifically, the two trunks 114 are electrically connected by a bridge portion 113 provided between a connection 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 a connection 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.

In other embodiments, the bridging portion 113 may also be provided between an electrode unit 12 in the third column and an electrode unit 12 in the fourth column. Alternatively, the bridging portion 113 may be provided between two electrode units 12 in the third and fourth columns that are adjacent in the row direction.

[0067] Each electrode unit 12 can be divided into an electrode unit 12 located at the periphery and an electrode unit 12 located at the center according to its position in the electrode array (unnumbered). The electrode units 12 located at the periphery include four electrode units 12 located in the first row, two electrode units 12 located at opposite ends of the second row, two electrode units 12 located at opposite ends of the third row, and four electrode units 12 located in the fourth row. The electrode units 12 located at the center include four electrode units 12 located in the middle of the second row and four electrode units 12 located in the middle of the third row. Some adjacent two electrode units 12 in the plurality of electrode units 12 located at the periphery are connected by a laterally arranged connecting portion 111, and some adjacent two electrode units 12 are arranged in a disconnected state. Among the plurality of electrode units 12 located at the periphery, the adjacent two electrode units 12 connected by the connecting portion 111 are two electrode units 12 that are adjacent in some rows. Specifically, among the plurality of electrode units 12 located at the periphery, two adjacent electrode units 12 in the column direction and two adjacent electrode units 12 in the diagonal direction are all disconnected; some adjacent electrode units 12 in the row direction are also disconnected; and only some adjacent electrode units 12 in the row direction are connected by a laterally extending connection portion 111. Among the plurality of electrode units 12 located at the center, only two adjacent electrode units 12 in the column direction on the trunk 114 are connected by a longitudinally arranged connection portion 111, and only two adjacent electrode units 12 in the row direction on the branches 115 are connected by a laterally arranged connection portion 111.

[0068] The electrode array (unnumbered) also includes spaces (unnumbered) formed between the spaced electrode units 12. These spaces allow moisture from the patient's body to escape, heat exchange between the patient's skin and the surrounding environment, and allow the patient's skin to breathe freely. They also allow for flexible adjustment of the position and spacing between the branches 115 and prevent wrinkles when the electrode sheet 10 is applied. The spaces (unnumbered) include a first space D1 between the two trunks 114 and a second space D2 between the branches 115. The first space D1 is located between the third and fourth columns of electrode units 12, while the second space D2 is located between adjacent rows of electrode units 12. That is, going up along the row, the electrode unit 12 located in the third column is disconnected from the adjacent electrode unit 12 located in the fourth column, and no connecting portion 111 is provided, but the aforementioned first interval D1 is formed; and going up along the column, only the two adjacent electrode units 12 in the third and fourth columns are connected by the connecting portion 111, and the two adjacent electrode units 12 in the column direction in each of the other four columns are not connected by the connecting portion 111 but form the aforementioned second interval D2. The setting of the first and second intervals D1 and D2 can also increase the degree of freedom of some electrode units 12, and can also avoid wrinkles when attaching the electrode sheet 10.

[0069] In some other embodiments, the tumor electric field therapy system 100 may also have more or fewer electrode sheets 10. In some other embodiments, each pair of electrode sheets 10 has the same number of electrode units 12, and different pairs of electrode sheets 10 may 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 sheet 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 of the electrode units 12 of the electrode sheet 10.

[0070] The electrode sheet 10' shown in FIG2 is a variation of the electrode sheet 10 shown in FIG1. ​​The spatial structure of the electrode sheet 10' is the same as that of the electrode sheet 10, and also includes a plurality of electrode units 12' arranged at intervals, a plurality of connecting portions 111' located between two adjacent electrode units 12', a wiring portion 112' connected to the bridging portion 113', and a first cable 13' connected to the wiring portion 112', a first interval D1 formed between the third column electrode unit 12' and the fourth column electrode unit 12', and a second spacing D1 formed between the electrode units 12' in adjacent rows. The only difference is that: the two electrode units 12' adjacent to each other in the column direction in the fourth column are both disconnected and not connected by the longitudinally arranged connecting portion 111', but the two electrode units 12' adjacent to each other in the column direction in the fifth column are connected by the longitudinally arranged connecting portion 111', and each electrode unit 12' in the fourth column is connected to the electrode unit 12' in the fifth column and adjacent to each other in the row direction through the transversely arranged connecting portion 111'; and the bridging portion 113' is connected between the two electrode units 12' located in the third row and the third column and the electrode unit 12' located in the third row and the fourth column.

[0071] FIG3 is a schematic diagram of a circuit connection between the first embodiment of the electrode sheet 10 or its variant embodiment, the electrode sheet 10′, and the adapter 20 of the first embodiment, shown in FIG1 . It is important to note that the arrangement of the electrode units 12 shown in FIG3 is intended to more clearly illustrate the electrical connection between an electrode sheet 10 and the adapter 20. The arrangement of the electrode units 12 shown in FIG3 does not represent the spatial arrangement of the electrode units 12. The following describes the circuit connection using the electrode sheet 10 of the first embodiment as an example. Referring to FIG1 and FIG3 , the flexible circuit board 11 is embedded with multiple conductive traces 18, 19, including multiple grounding wires 18 and multiple dual-purpose signal wires 19. The first cable 13 includes multiple core conductors (not shown) that are electrically connected to the multiple grounding wires 18 and the multiple dual-purpose signal wires 19 of the flexible circuit board 11, one-to-one. The total number of grounding wires 18 and dual-purpose signal wires 19 embedded in the flexible circuit board 11 does not exceed 10. Therefore, the number of conductors of the first cable 13 does not exceed ten.

[0072] In this embodiment, each electrode sheet 10 is provided with 20 electrode units 12. The 20 electrode units 12 are arranged in the order of 1 to 20 for circuit connection, divided into four row groups and five column groups. That is, the 20 electrode units 12 are arranged in four rows and five columns for 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 temperature sensor 14 of each electrode unit 12 are soldered to the flexible circuit board 11, and each dielectric element 15 is short-circuited with the signal terminal 14-2 of the corresponding temperature sensor 14. Because the electrode units 12 are arranged in four rows and five columns for circuit connection, and each electrode unit includes a corresponding dielectric element 15 and a corresponding temperature sensor 14, the multiple temperature sensors 14 are also arranged in four rows and five columns for circuit connection, and the multiple dielectric elements 15 are also arranged in four rows and five columns for circuit connection. It should be noted that the arrangement here is to more clearly illustrate the electrical connection between the electrode sheet 10 and the adapter 20, and does not represent the arrangement of the electrode unit 12 in the spatial structure. Its spatial structure may be a roughly array structure as shown in Figure 1, or it may be other structures, such as petal-shaped or scattered, etc., and it may be a regular or irregular structure. The dielectric element 15 is configured to apply an alternating electric field to the patient's tumor site. The temperature sensor 14 is configured to detect the temperature of the patient's body surface attached to the electrode sheet 10 and output a temperature detection signal to the adapter 20. In this embodiment, the multiplexed signal lines 19 of the flexible circuit board 11 are respectively arranged in a one-to-one correspondence with the multiple column groups of the electrode unit 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 in the corresponding column group. That is, the dielectric components 15 in the same column group are short-circuited via the same dual-purpose signal line 19 on the flexible circuit board 11, while the dielectric components 15 in different column groups are connected in parallel via different dual-purpose signal lines 19 on the flexible circuit board 11. The dual-purpose signal lines 19 on the flexible circuit board 11 are electrically connected one by one to corresponding wires in the first cable 13, and then electrically connected to the electric field generator 30 via the adapter 20. In other words, the dual-purpose signal lines 19 on the flexible circuit board 11 receive the AC signal generated by the electric field generator 30 via the first cable 13 and the adapter 20.

[0073] Multiple grounding wires 18 are provided in a one-to-one correspondence with the multiple row groups of electrode units 12. These wires are used to sequentially short-circuit the temperature sensors 14 of each electrode unit 12 in each row group to ground. Specifically, the ground terminals 14-1 of the temperature sensors 14 in the same row group are all short-circuited via the same grounding wire 18 on the flexible circuit board 11. The ground terminals 14-1 of the temperature sensors 14 in different row groups are each connected to ground in parallel via different grounding wires 18 on the flexible circuit board 11. During the temperature detection period or in the second mode, only one of the multiple grounding wires 18 is connected at any one time; the remaining grounding wires are disconnected.

[0074] Each of the two-way dual-purpose signal lines 19 is further configured to transmit a DC signal to the temperature sensor 14 in each electrode unit 12 in the corresponding column group, thereby collecting and transmitting the detected temperature signal. The signal terminals 14-2 of the temperature sensors 14 in different column groups are connected in parallel via different dual-purpose signal lines 19 on the flexible circuit board 11. The signal terminals 14-2 of the temperature sensors 14 in the same column group are all short-circuited to the same dual-purpose signal line 19 on the flexible circuit board 11. Specifically, each dual-purpose signal line 19 is configured to short-circuit the signal terminal 14-2 of the temperature sensor 14 in at most one electrode unit 12 in each row group to an external device for receiving detection signals. Each of the two-way dual-purpose signal lines 19 is connected to a different signal terminal 14-2 of each temperature sensor 14 to prevent duplicate signals from being subsequently output by the dual-purpose signal lines 19. That is, when the number of electrode units 12 in a row group is the same as the number of dual-purpose signal lines 19, each dual-purpose signal line 19 is electrically connected to the signal end 14-2 of the temperature sensor 14 of a different electrode unit 12 in the row group. When the number of electrode units 12 in a row group is less than the number of dual-purpose signal lines 19, at least one dual-purpose signal line 19 is not electrically connected to the signal end 14-2 of the temperature sensor 14 of an electrode unit 12, and each of the remaining dual-purpose signal lines 19 is electrically connected to the signal end 14-2 of the temperature sensor 14 of a different electrode unit 12 in the row group. In this embodiment, the external device for receiving the detection signal is an adapter 20. The dual-purpose signal lines 19 of the flexible circuit board 11 receive the DC signal from the adapter 20 or the electric field generator 30 via the first cable 13, and transmit the collected or detected temperature signal to the adapter 20, and then transmit it to the electric field generator 30 via the adapter 20.

[0075] In this embodiment, when each electrode unit 12 is equipped with a temperature sensor 14 for temperature detection, the above-mentioned circuit design is used to reduce the number of conductors of the first cable 13, thereby avoiding the cable becoming thicker and the cable becoming harder, which increases the difficulty of fixing the cable; at the same time, it is avoided that the increase in the number of conductors of the first cable 13 affects the adhesion effect between the electrode sheet 10 and the body surface corresponding to the tumor site of the patient. The grounding wire 18 and the dual-purpose signal wire 19 embedded in the flexible circuit board 11 are a total of 9 lines. Specifically, in this embodiment, the grounding wire 18 embedded in the flexible circuit board 11 is 4 lines, and the dual-purpose signal wire 19 is 5 lines. In other embodiments, the grounding wire 18 and the dual-purpose signal wire 19 embedded in the flexible circuit board 11 can also have other numbers according to the circuit arrangement and number differences of the electrode units 12 in different electrode sheets, which will be specifically explained in subsequent embodiments.

[0076] In the tumor electric field therapy system 100, the number of conductive lines electrically connected to the ground line 18 is related to the number M of row groups of the electrode units 12, which 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 lines electrically connected to the dual-purpose signal lines 19 is related to the number N of column groups of the electrode units 12, which 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 lines L embedded in the flexible circuit board 11 of the electrode sheet 10 is equal to the sum of the number of ground lines 18 and the number of dual-purpose signal lines 19. In this embodiment, the number of ground lines 18 is equal to the number M of row groups of the electrode units 12; the number of dual-purpose signal lines 19 is equal to the number N of column groups of the electrode units 12.

[0077] In the embodiment shown in FIG3 , the electrode sheet 10 includes four grounding wires 18, each of which is used to ground the ground terminals 14-1 of the temperature sensors 14 in the same row group. The four grounding wires 18 of the electrode sheet 10 are a first grounding wire 18-1, a second grounding wire 18-2, a third grounding wire 18-3, and a fourth grounding wire 18-4. Of 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 grounding wire 18-1 is used to ground the electrode units 12-1 to 12-5 in the first row group; the second grounding wire 18-2 is used to ground the electrode units 12-6 to 12-10 in the second row group; the third grounding wire 18-3 is used to ground the electrode units 12-11 to 12-15 in the third row group; and the fourth grounding 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 grounding wires 18 can be selectively closed or opened, which can be achieved by connecting each grounding wire 18 in series with a switch, which will be described in detail below. The above-mentioned "grounding the electrode unit 12" can refer to grounding the ground terminal 14-1 of the temperature sensor 14 in the electrode unit 12, or it can 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 line 18 short-circuits the ground terminals 14 - 1 of the temperature sensors 14 of all the electrode units 12 in each row group and connects them to the ground.

[0078] Continuing with reference to FIG3 , the electrode sheet 10 of this embodiment further includes five dual-purpose signal lines 19. One end of each dual-purpose signal line 19 is connected to all electrode units 12 in each column group, and the other end is connected to an adapter 20 for receiving temperature detection signals and transmitting AC signals. That is, for each row group, each dual-purpose signal line 19 can selectively connect to one of the electrode units 12 or not connect to any of the electrode units 12 in that row group, thereby preventing the dual-purpose signal lines 19 from subsequently outputting duplicate signals. Specifically, the five dual-purpose signal lines 19 of the electrode sheet 10 include a first dual-purpose signal line 19-1, a second dual-purpose signal line 19-2, a third dual-purpose signal line 19-3, a fourth dual-purpose signal line 19-4, and a fifth dual-purpose signal line 19-5. One end of the first dual-purpose signal line 19-1 is connected to the dielectric elements 15 of the four electrode units 12, namely, electrode unit 12-1, electrode unit 12-6, electrode unit 12-11, and electrode unit 12-16, and the signal end 14-2 of the temperature sensor 14 of each of the four electrode units 12; one end of the second dual-purpose signal line 19-2 is connected to the dielectric elements 15 of the four electrode units 12, namely, electrode unit 12-2, electrode unit 12-7, electrode unit 12-12, and electrode unit 12-17, and the signal end 14-2 of the temperature sensor 14 of each of the four electrode units 12; one end of the third dual-purpose signal line 19-3 is connected to the dielectric elements 15 of the four electrode units 12, namely, electrode unit 12-3, electrode unit 12-8, and electrode unit 12-1, respectively. 3. Electrode units 12-18: The dielectric elements 15 of each of the four electrode units 12 and the signal terminals 14-2 of each temperature sensor 14. One end of a fourth dual-purpose signal line 19-4 is simultaneously connected to the dielectric elements 15 of each of the four electrode units 12, namely, electrode unit 12-4, electrode unit 12-9, electrode unit 12-14, and electrode unit 12-19, and the signal terminals 14-2 of each temperature sensor 14. One end of a fifth dual-purpose signal line 19-5 is simultaneously connected to the dielectric elements 15 of each of the four electrode units 12, namely, electrode unit 12-5, electrode unit 12-10, electrode unit 12-15, and electrode unit 12-20, and the signal terminals 14-2 of the temperature sensor 14. In short, each dual-purpose signal line 19 parallel-circuits the dielectric elements 15 and the signal terminals 14-2 of each temperature sensor 14 of each electrode unit 12 in the same column group, and is used for connection to an external device. It should be noted that these dual-purpose signal lines 19 can selectively transmit AC signals or receive temperature detection signals. This can be achieved by connecting each dual-purpose signal line 19 in series with a bidirectional switch 26 and coordinating the closing or opening of the grounding line 18. This will be described in detail below.

[0079] Multiple ground lines 18 and multiplexed signal lines 19 are conductive traces embedded within the flexible printed circuit board 11. The flexible printed circuit board 11 is electrically connected to the first cable 13. The multiple ground lines 18 and multiplexed signal lines 19 embedded within the flexible printed circuit board 11 are electrically connected to corresponding wires (not shown) within the first cable 13.

[0080] The tumor electric field therapy system 100 of this embodiment includes at least one pair of the above-mentioned electrode sheets 10, an adapter 20 electrically connected to the electrode sheets 10, and an electric field generator 30 electrically connected to the adapter 20. The adapter 20 is connected between the electrode sheets 10 and the electric field generator 30. The electric field generator 30 provides an AC signal or a DC signal to the dielectric elements 15 in the multiple electrode units 12 of the electrode sheet 10 via the adapter 20 and the dual-purpose signal line 19 of the electrode sheet 10, and is used to receive temperature detection signals output by the temperature sensors 14 in the multiple electrode units 12. The adapter 20 is configured to transmit the AC signal generated by the electric field generator 30 to the dual-purpose signal line 19 of the electrode sheet 10, and is also configured to transmit a DC signal to the dual-purpose signal line 19 of the electrode sheet and receive the temperature detection signal output by the multiple dual-purpose signal line 19 of the electrode sheet 10.

[0081] 3 and 4 , the adapter 20 includes: a first controller 22, multiple analog-to-digital converters 23 connected to the first controller 22, multiple sets of voltage transformers 24 corresponding one-to-one to the multiple analog-to-digital converters 23, multiple sets of grounding switches 25 and multiple sets of bidirectional switches 26, a first communication unit 27, multiple AC signal lines 28 connected one-to-one to the multiple sets of bidirectional switches 26, and a first power supply module 29 connected to the first communication unit 27, the first controller 22, and the multiple analog-to-digital converters 23. The first power supply module 29 provides a DC power supply VCC for each electronic component of the adapter 20. The adapter 20 also includes multiple circuit lines (unnumbered). The multiple circuit lines (unnumbered) are electrically connected one-to-one to the multiple grounding lines 18 and the multiple dual-purpose signal lines 19 in the flexible circuit board 11 of the corresponding electrode sheet 10 through the first cables 13 of the corresponding electrode sheet 10. The multiple circuit lines (unnumbered) include multiple AC signal lines 28 that transmit alternating current signals to corresponding electrode sheets 10 and are electrically connected to the multiplexed signal lines 19 within the flexible circuit boards 11 of the corresponding electrode sheets 10, multiple circuit lines (unnumbered) that are electrically connected one-to-one with the multiplexed signal lines 19 within the flexible circuit boards 11 of the corresponding electrode sheets 10 and are used to power the temperature sensors 14 of the electrode sheets 10 or transmit temperature detection signals for the electrode sheets 10, and multiple circuit lines (unnumbered) that are electrically connected one-to-one with the multiple ground lines 18 within the flexible circuit boards 11 of the corresponding electrode sheets 10. The number P of circuit lines electrically connected by the adapter 20 to one electrode sheet 10 is equal to the sum of the number M of rows and the number N of columns of the electrode units 12 of the electrode sheet 10 plus 1; the number H of circuit lines electrically connected by the adapter 20 to X electrode sheets 10 is equal to X times the number of circuit lines electrically connected to a single electrode sheet 10, that is, H = XP = X*(M+N+1). The number of grounding switches 25 and the number of bidirectional switches 26 are both related to the number of electrode sheets 10. The number of grounding switches 25 and the number of bidirectional switches 26 are the same and no less than the number of electrode sheets 10. Preferably, the number of grounding switches 25 and the number of bidirectional switches 26 are both the same as the number of electrode sheets 10. The following detailed description will only use the example of an electrode sheet 10 having 20 electrode units 12 and the adapter 20 for electrical connection.

[0082] Each set of grounding switches 25 is equipped with multiple grounding switches 25. The multiple grounding switches 25 are respectively connected to the adapter 20 and electrically connected to the circuit lines (not numbered) corresponding to the multiple grounding lines 18 of the corresponding electrode sheet 10, and are configured to control the conduction or disconnection of the multiple grounding lines 18. The circuit lines (not numbered) electrically connected to the multiple grounding lines 18 of the electrode sheet 10 are grounded at one end near the grounding switches 25. The number of grounding switches 25 in each set of grounding switches 25 is related to the number of grounding lines 18 of the flexible circuit board 11 of the corresponding electrode sheet 10, and in this embodiment, the two are equal. As shown in Figure 3, in this embodiment, each set of grounding switches 25 is equipped with multiple grounding switches 25, and in this embodiment, there are four grounding switches 25, namely a first grounding switch 25-1, a second grounding switch 25-2, a third grounding switch 25-3, and a fourth grounding switch 25-4. The multiple grounding switches 25 in each set control the conduction or disconnection of the corresponding grounding line 18 of the corresponding electrode sheet 10. Specifically, the first grounding switch 25-1 is used to control the closing or disconnection of the first grounding line 18-1 of the corresponding electrode sheet 10, and can then cooperate with the corresponding group of two-way switching switches 26 to control the power on and off of each temperature sensor 14 of the five electrode units 12 from electrode unit 12-1 to electrode unit 12-5 in the first row group of the electrode sheet 10; the second grounding switch 25-2 is used to control the closing or disconnection of the second grounding line 18-2 of the electrode sheet 10, and can then cooperate with the corresponding group of two-way switching switches 26 to control the power on and off of each temperature sensor 14 of the five electrode units 12 from electrode unit 12-6 to electrode unit 12-10 in the second row group of the electrode sheet 10. The third grounding switch 25-3 is used to control the closing or disconnection of the third grounding line 18-3 of the electrode sheet 10, and can then cooperate with the corresponding group of two-way switching switches 26 to control the power on and off of each temperature sensor 14 of the five electrode units 12 in the third row group of the electrode sheet 10, from electrode unit 12-11 to electrode unit 12-15; the fourth grounding switch 25-4 is used to control the closing or disconnection of the fourth grounding line 18-4 of the electrode sheet 10, and can then cooperate with the corresponding group of two-way switching switches 26 to control the power on and off of each temperature sensor 14 of the five electrode units 12 in the fourth row group of the electrode sheet 10, from electrode unit 12-16 to electrode unit 12-20. 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 by the first controller 22 of the adapter 20.

[0083] In this embodiment, the multiple groups of grounding switches 25 are all electronic switches. The first controller 22 is in communication with the multiple groups of grounding switches 25 and is configured to sequentially and cyclically control the opening and closing states of the multiple grounding switches 25 in each group of grounding switches 25. This in turn sequentially connects each of the multiple grounding wires 18 of the corresponding electrode sheet 10 and coordinates the switching of the corresponding bidirectional switch 26 to sequentially and time-share the patient's body surface temperature detected by all temperature sensors 14 on the electrode sheet 10. The number of grounding switches 25 in each group is greater than or equal to the number of grounding wires 18 on the flexible circuit board 11 of the corresponding electrode sheet 10. In this embodiment, the number of grounding switches 25 in each group is the same as the number of grounding wires 18 of the corresponding electrode sheet 10.

[0084] Each group of bidirectional switches 26 is provided with a plurality of bidirectional switches 26. The plurality of bidirectional switches 26 in each group are respectively connected to the adapter 20 and are respectively electrically connected to the circuit lines (not numbered) corresponding one-to-one to the multi-channel dual-purpose signal lines 19 of the corresponding electrode sheet 10. The number of bidirectional switches 26 in each group of bidirectional switches 26 is related to the number of dual-purpose signal lines 19 of the flexible circuit board 11 of the corresponding electrode sheet 10, which is greater than or equal to the number of dual-purpose signal lines 19 of the flexible circuit board 11 of the corresponding electrode sheet 10. In the embodiment shown in Figure 3, the two are equal. Each bidirectional switch 26 has two ends 1 and 2. The acquisition end 1 of the plurality of bidirectional switches 26 in the same group is respectively electrically connected one-to-one to the corresponding detection channels of the plurality of detection channels of the corresponding group of analog-to-digital converters 23, and the input end 2 of each bidirectional switch 26 in the same group is electrically connected to the corresponding same AC signal line 28. Each bidirectional switch 26 is configured to control the multiplex signal line 19 to access the corresponding AC signal line 28 to transmit an alternating current signal or to access the corresponding detection channel of the corresponding group of analog-to-digital converters 23 to receive the temperature detection signal output by the temperature sensor 14 .

[0085] As shown in FIG3 , taking the electrical connection between one electrode sheet 10 and the adapter 20 as an example, in this embodiment having 20 electrode units 12, the plurality of bidirectional switches 26 are respectively a first bidirectional switch 26-1, a second bidirectional switch 26-2, a third bidirectional switch 26-3, a fourth bidirectional switch 26-4, and a fifth bidirectional switch 26-5. The plurality of bidirectional switches 26 in the same group each control a corresponding one of the multiplexed signal lines 19 of the same electrode sheet 10 to switch between transmitting an AC signal and transmitting a temperature detection signal.

When the input terminal 2 of each set of bidirectional switches 26 is on and the acquisition terminal 1 is off, an AC signal can be transmitted to the dielectric element 15 of each electrode unit 12 of the corresponding electrode sheet 10. When the acquisition terminal 1 of each set of bidirectional switches 26 is on and the input terminal 2 is off, the switches 26 can cooperate with each of the corresponding set of grounding switches 25 to time-share the temperature detection signals collected by the temperature sensors 14 of each electrode unit 12 on the electrode sheet 10. The bidirectional switches 26 can be mechanical switches, such as relays. Alternatively, they can be electronic switches. The switching between the acquisition terminal 1 and the input terminal 2 of each bidirectional switch 26 can be controlled by the first controller 22 of the adapter 20.

[0086] In this embodiment, the plurality of sets of bidirectional switches 26 are all electronic switches. The first controller 22 is in communication with the plurality of sets of bidirectional switches 26 and is configured to control the plurality of bidirectional switches 26 in each set of bidirectional switches 26 to switch between their respective acquisition terminals 1 and input terminals 2, and to coordinate with the closing or opening of the corresponding grounding switches 25 to continuously monitor the patient's body surface temperature detected by all temperature sensors 14 on the electrode sheet 10 or to transmit an AC signal to the patient.

[0087] In this embodiment, each group of analog-to-digital converters 23 is electrically connected to the collection terminals 1 of the multiple bidirectional switching switches 26 in the corresponding group of bidirectional switching switches 26 through the multi-channel circuit lines (unnumbered) in the adapter 20, and is configured to receive the temperature detection signal transmitted by the multiplexed signal line 19 of the corresponding electrode sheet 10, and convert the temperature detection signal from an analog signal to a digital signal. Each group of analog-to-digital converters 23 includes multiple detection channels A, B, C, D, and E, and each detection channel A, B, C, D, and E is used to connect to a corresponding one-way dual-purpose signal line 19 in the multiplexed signal line 19 through the corresponding bidirectional switching switch 26. The number of detection channels in each group of analog-to-digital converters 23 is related to the number of bidirectional switching 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 electrode units 12 of the corresponding electrode sheet 10. Specifically, the number of detection channels in each set of analog-to-digital converters 23 is equal to the number of bidirectional switches 26 in the corresponding set of bidirectional switches 26, which is not less than the number of column groups of electrode units 12 of the corresponding electrode sheet 10. As shown in FIG3 , each set of analog-to-digital converters 23 includes a total of five detection channels A, B, C, D, and E, which are respectively a first detection channel A, a second detection channel B, a third detection channel C, a fourth detection channel D, and a fifth detection channel E.

Each detection channel A, B, C, D, and E is configured to receive a temperature detection signal collected by the temperature sensor 14 of the electrode unit 12 connected to the corresponding dual-purpose signal line 19. Furthermore, each detection channel A, B, C, D, and E is connected via a corresponding voltage divider resistor 24 within the adapter 20 to a first power module 29 for providing a detection voltage to that detection channel A, B, C, D, and E. The first power module 29 provides a DC signal.

[0088] In this embodiment, the first communication unit 27 is configured to obtain the digital signals output by the multiple analog-to-digital converters 23 and send the digital signals to the electric field generator 30. The electric field generator 30 is also configured to control and adjust the voltage, current, or power of the AC signal provided to the multiple electrode units 12 of the electrode sheet 10 based on the received digital signals. For example, when any of the multiple digital signals received exceeds a preset threshold, it indicates that the temperature of the human body surface to which the corresponding dielectric element 15 is applied, detected by at least one temperature sensor 14 in the electrode sheet 10, exceeds a preset threshold temperature (e.g., 41°C, 42°C, etc.). At this time, the voltage, current, or power of the AC signal output by the electric field generator 30 can be appropriately reduced to prevent the electrode units 12 of the electrode sheet 10 from becoming too hot when the AC signal is applied, thereby causing low-temperature burns to the patient's skin. The above-mentioned preset threshold temperature and preset threshold value can be determined based on the human body safety threshold. The first communication unit 27 is controlled by the first controller 22 and serially transmits the digital signals converted by the multiple analog-to-digital converters 23. In this embodiment, the preset temperature threshold may be a value within the range of 36°C-45°C.

Each first connector 40, such as X1, Y1, X2, and Y2, connects a corresponding set of grounding switches 25 to a corresponding set of analog-to-digital converters 23. Specifically, each first connector 40 is simultaneously connected to the second connector 50 and a corresponding set of analog-to-digital converters 23 via a corresponding set of bidirectional switches 26. Taking four electrode sheets 10 as an example, the second cable 21 has eight conductors: four conductors 1 to 4 electrically connected to corresponding AC signal lines 28 for transmitting AC signals; one conductor 5 electrically connected to the data receiving line RX of the first communication unit 27; one conductor 6 electrically connected to the data transmitting line TX of the first communication unit 27; one conductor 7 electrically connected to the VCC power line of the first power module 29; and one conductor 8 electrically connected to the GND line of the first power module 29.

[0093] The working principle of the tumor electric field treating system 100 of this embodiment will be described in detail below with reference to FIG. 3 to FIG. 5 .

[0094] Specifically, when it is necessary to detect the temperature of each electrode unit 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 the collection end 1 of each of the multiple bidirectional switching switches 26 of a group of bidirectional switching switches 26 electrically connected to the electrode sheet 10 to be turned on and the input end 2 to be disconnected, so as to disconnect the AC 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 of the grounding switches 25 in a group of grounding switches 25 electrically connected to the electrode sheet 10 to be turned on in sequence. At this time, the temperature detection signals collected by each temperature sensor 14 of each electrode unit 12 of each row group of the electrode sheet 10 can be collected in sequence through 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 signal of the temperature sensor 14 corresponding to the electrode unit 12 of each electrode unit 12 in the same row group of the electrode sheet 10 at the same time. The above-mentioned temperature detection signal can be represented by a voltage value. Among the four grounding switches 25 in a group of grounding switches 25 corresponding to the electrode sheet 10, only one grounding switch 25 can be turned on at the same time, and the other three are turned off. Among the five bidirectional switching switches 26 in a group of bidirectional switching switches 26 corresponding to the group of analog-to-digital converters 23, all five bidirectional switching switches 26 are switched to their respective collection terminals 1 so that each dual-purpose signal line 19 of the electrode sheet 10 is electrically connected to the corresponding detection channel A, B, C, D, and E of the corresponding group of analog-to-digital converters 23 in a one-to-one correspondence and is turned on. With this arrangement, the group of analog-to-digital converters 23 can collect the voltage value of the temperature sensor 14 of each electrode unit 12 in the same row group that is short-circuited with the grounding line 18 corresponding to the turned-on grounding switch 25.

[0095] Specifically, when the first grounding switch 25-1 is closed, the second grounding switch 25-2, the third grounding switch 25-3, and the fourth grounding switch 25-4 are all opened, 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 terminals 1, the temperature sensors 14 of the electrode units 12-1 to 12-5 of the first row group are powered on, and the temperature sensors 14 of the electrode units 12-6 to 12-20 of the remaining row groups are powered off, and the first detection channel A in the analog-to-digital converter 23 of the group short-circuits the electrode units 12-1, 12-6, 12-11, and 12-16, respectively. Regarding the signal terminal 14-2 of the temperature sensor 14 of electrode unit 12-1, only the ground terminal 14-1 of the temperature sensor 14 of electrode unit 12-1 is connected to ground, while the ground terminals 14-1 of the temperature sensors 14 of electrode units 12-6, 12-11, and 12-16 are all disconnected. Furthermore, each electrode unit 12 is provided with a diode 16 connected in series with the temperature sensor 14. The remaining temperature sensors 14 in the first row do not affect the resistance of the temperature sensor 14 of electrode unit 12-1. Therefore, only the temperature sensor 14 of electrode unit 12-1 is effectively operating on the first detection channel A of the group of analog-to-digital converters 23. The temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature sensor 14 of electrode unit 12-1. Similarly, the voltage value collected by the second detection channel B of the group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of electrode unit 12-2. The voltage value collected by the third detection channel C of the group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of electrode unit 12-3. The voltage value collected on the fourth detection channel D of the ADC 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-4. The voltage value collected on the fifth detection channel E of the ADC 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-5.

[0096] When the second grounding switch 25-2 is closed, the first grounding switch 25-1, the third grounding switch 25-3 and the fourth grounding switch 25-4 are all opened, 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 terminals 1, the temperature sensors 14 of the electrode units 12-6 to 12-10 of 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 of the remaining row groups are powered off, and the first detection channel A in the analog-to-digital converter 23 of the group short-circuits the electrode units 12-1, 12-6, 12-11 and 12-20. Since only the ground terminal 14-1 of the temperature sensor 14 of electrode unit 12-6 is connected to the ground, and the ground terminals 14-1 of the temperature sensors 14 of electrode units 12-1, electrode units 12-11, and electrode units 12-16 are all disconnected, and each electrode unit 12 is provided with a diode 16 connected in series with the temperature sensor 14, the remaining temperature sensors 14 in the second row will not affect the resistance value of the temperature sensor 14 of electrode unit 12-6. Therefore, only the temperature sensor 14 of electrode unit 12-6 is effectively operating on the first detection channel A of the 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 electrode unit 12-6. Similarly, the voltage value collected by the second detection channel B in the group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of electrode unit 12-7. The voltage value collected by the third detection channel C in the set 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 the set 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 the set of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-10.

[0097] 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 opened, 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 terminals 1, the temperature sensors 14 of the electrode units 12-11 to 12-15 of 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 of the remaining row groups are powered off, and the first detection channel A in the analog-to-digital converter 23 of the group short-circuits the electrode units 12-1, 12-6, 12-11, and 12-20. Since only the ground terminal 14-1 of the temperature sensor 14 of electrode unit 12-11 is connected to the ground, and the ground terminals 14-1 of the temperature sensors 14 of electrode units 12-1, electrode units 12-6, and electrode units 12-16 are all disconnected, and each electrode unit 12 is provided with a diode 16 connected in series with the temperature sensor 14, the remaining temperature sensors 14 in the third row will not affect the resistance value of the temperature sensor 14 of electrode unit 12-11. Therefore, only the temperature sensor 14 of electrode unit 12-11 is effectively operating on the first detection channel A of the 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 electrode unit 12-11. Similarly, the voltage value collected by the second detection channel B in the group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of electrode unit 12-12. The voltage value collected by the third detection channel C in the set of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode units 12-13. The voltage value collected by the fourth detection channel D in the set of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode units 12-14. The voltage value collected by the fifth detection channel E in the set of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode units 12-15.

[0098] 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 opened, 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 terminals 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, and the first detection channel A in the analog-to-digital converter 23 of the group short-circuits the temperature sensors of the electrode units 12-1, 12-6, 12-11 and 12-16. Since only the ground terminal 14-1 of the temperature sensor 14 of electrode unit 12-16 is connected to the ground, and the ground terminals 14-1 of the temperature sensors 14 of electrode unit 12-1, electrode unit 12-6, and electrode unit 12-11 are all disconnected, and each electrode unit 12 is provided with a diode 16 connected in series with the temperature sensor 14, the remaining temperature sensors 14 in the fourth row will not affect the resistance value of the temperature sensor 14 of electrode unit 12-16. Therefore, only the temperature sensor 14 of electrode unit 12-16 is effectively operating on the first detection channel A of the 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 electrode unit 12-16. Similarly, the voltage value collected by the second detection channel B in the group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of electrode unit 12-17. The voltage value collected on the third detection channel C in the 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 in the 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 in the 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 realize the collection of temperature detection signals of the temperature sensors 14 of all electrode units 12 of a certain electrode sheet 10 by controlling a group of bidirectional switching switches 26 and a group of grounding switches 25 that are electrically connected to the electrode sheet 10. Similarly, the temperature detection signals of the temperature sensors 14 of each electrode unit 12 of other electrode sheets 10 can be obtained.

[0099] The first controller 22, the plurality of analog-to-digital converters 23, and the plurality of bidirectional switches 26 can automatically perform operations according to 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 terminal 1, so that the acquisition terminals 1 of the bidirectional switches 26 are all turned on and the input terminals 2 are all turned off, so that the dual-purpose signal lines 19 of the corresponding electrode sheets 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 switches 25-2, third grounding switches 25-3 to fourth grounding switches 25-4 in the group of grounding switches 25 are turned off. During this period, the group Each detection channel A, B, C, D, and E of the analog-to-digital converter 23 acquires the temperature detection signals of each temperature sensor 14 of each electrode unit 12 located in the first row group of the corresponding electrode sheet 10, converts them into digital signals, and stores them in a separately provided memory. Then, after a preset interval, the first controller 22 closes the second grounding switch 25-2 in the group of grounding switches 25 and opens the first grounding switch 25-1, the third grounding switch 25-3, and the fourth grounding switch 25-4 in the group of grounding switches 25. During this period, each detection channel A, B, C, D, and E of the analog-to-digital converter 23 acquires the temperature detection signals of each temperature sensor 14 of each electrode unit 12 located in the second row group. By sequentially opening each grounding switch 25 in the group of grounding switches 25, the temperature detection signals of all temperature sensors 14 located in each row group of the electrode sheet 10 can be obtained. Similarly, through this operation, the temperature detection signals of all temperature sensors 14 on at least one pair of electrode sheets 10 are obtained.

[0100] The tumor electric field therapy system 100 of the present application can realize real-time and comprehensive monitoring of the temperature of all electrode units 12 on the electrode sheet 10 without increasing the weight of the electrode sheet 10 or adding the core of the first cable 13 electrically connected to the electrode sheet 10, and then determine whether the electrode sheet 10 is qualified based on the obtained temperature detection signal; or determine whether the temperature sensor 14 of the electrode sheet 10 is faulty or abnormal based on the obtained temperature detection signal, and determine whether the electrode sheet 10 needs to be replaced based on the number of faulty or abnormal temperature sensors 14 obtained; or if the electrode sheet is qualified, identify the type of electrode sheet based on the obtained temperature detection signal; or if the electrode sheet is qualified, determine whether the electrode unit 12 of the electrode sheet 10 is overheated based on the obtained temperature detection signal, and then control the alternating electric signal applied to the electrode sheet 10 or the electrode unit 12 of the corresponding column of the electrode sheet 10, so as to avoid low-temperature burns on the patient's body surface when tumor treatment is performed through the electrode sheet 10. In addition, the flexible circuit board 11 of the electrode sheet 10 of the present application is electrically connected to 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. While it can transmit both an AC signal and a DC signal for temperature signal acquisition and the collected temperature detection signal through the dual-purpose signal line 19, it also greatly reduces the number of conductive traces (grounding line 18, dual-purpose signal line 19) arranged thereon, thereby reducing the wiring difficulty of the flexible circuit board 11, simplifying the manufacturing process, reducing the weight of the flexible circuit board 11, and reducing manufacturing costs. The electrode sheet 10 of the present application can also switch between applying an AC signal for tumor treatment and transmitting a DC signal for temperature acquisition and the collected temperature detection signal through the combined control of a grounding switch 25 electrically connected to the grounding line 18 arranged thereon and a bidirectional switching switch 26 electrically connected to the dual-purpose signal line 19.

[0101] When it is necessary to apply an alternating current signal to the patient through 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 all the grounding switches 25 in a group of grounding switches 25 corresponding to the electrode sheet 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 sheet 10 to be switched to their respective input ends 2, so that the collection ends 1 of the bidirectional switching switches 26 are all disconnected and the input ends 2 are all turned on, so that the dual-purpose signal lines 19 of the electrode sheet 10 are electrically connected to the adapter 20 and an AC signal line 28 corresponding to the electrode sheet 10, thereby transmitting the alternating current signal to the electrode units 12 of the electrode sheet 10.When the temperature detection signals of the temperature sensors 14 of all the electrode units 12 of the electrode sheet 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 to generate an AC signal with an increased voltage or current amplitude or a constant voltage or current amplitude, and then transmits it to the corresponding pair of electrode sheets 10 through a corresponding AC signal line 28 of the adapter 20, so that the pair of electrode sheets 10 continue to apply the AC signal; when the temperature detection signals of the temperature sensors 14 of all the electrode units 12 of the electrode sheet 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 controls the AC signal generator 34 through its second controller 32 to continue to generate an AC signal with an increased voltage or current amplitude or a constant voltage or current amplitude, and then transmits it to the corresponding pair of electrode sheets 10 through a corresponding AC signal line 28 of the adapter 20, so that the pair of electrode sheets 10 continue to apply the AC signal; The 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, thereby reducing the voltage or current of the alternating current signal applied to the pair of electrode sheets 10; when it is detected that the temperature detection signal of the temperature sensor 14 of an electrode unit 12 in a certain electrode sheet 10 is greater than a preset temperature threshold, the electric field generator 30 controls the AC signal switch 35 electrically connected to the electrode sheet 10 to disconnect through the second controller 32 to stop applying the alternating current signal to the electrode sheet 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 in a group of bidirectional switches 26 electrically connected to the electrode sheet 10 26 are all switched from their input end 2 to the collection end 1, that is, the collection ends 1 of all the bidirectional switch 26 of a group of bidirectional switch 26 electrically connected to the electrode sheet 10 are all turned on and the input ends 2 are all disconnected, thereby stopping the application of the alternating electric signal to the electrode sheet 10; or, when it is detected that the temperature detection signal of the temperature sensor 14 of an electrode unit 12 of a certain electrode sheet 10 is 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 sheet 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 electrically connected to the electrode unit 12 of the electrode sheet 10 to be turned on. The switch 26 switches from its input end 2 to its collection end 1, and the second controller 32 of the electric field generator 30 or the first controller 22 of the adapter 20 simultaneously controls the input ends 2 of the remaining bidirectional switches 26 electrically connected to the electrode units 12 of the electrode sheet 10 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 to continue to maintain electrical connection, thereby stopping the application of the AC signal to all electrode units 12 in the column of the electrode unit 12 of the electrode sheet 10 whose temperature detection signals exceed the preset temperature threshold, and continuing to apply the AC signal to the electrode units 12 in the remaining columns of the electrode sheet 10 whose temperature detection signals do not exceed the preset temperature threshold. This implements the control method of the tumor electric field therapy system 100 for regional application of the AC signal based on the temperature detection signal.When an AC signal is applied, all grounding switches 25 are opened.

[0102] In the embodiment of the present application, the grounding switch 25 electrically connected to each of the multiple grounding lines 18 of the electrode sheet 10 and the bidirectional switch 26 electrically connected to each of the multiple dual-purpose signal lines 19 of the electrode sheet 10 are both provided in the adapter 20. However, in other embodiments, the grounding switch 25 electrically connected to the grounding line 18 and the bidirectional switch 26 electrically connected to the dual-purpose signal line 19 can also be provided on the electrode sheet 10 or provided in the electric field generator 30, which will not be described in detail here. In addition, the analog-to-digital converter 23 provided in the adapter 20 can also be provided in the electric field generator 30 and directly controlled by the second controller 32.

[0103] The present application also provides other embodiments of the electrode sheet 10 , and the differences among the multiple embodiments mainly lie in the different numbers of electrode units 12 and / or the different electrical connection arrangements of the electrode units 12 , which will be described below.

[0104] As shown in FIG6 , an electrode sheet 10A of the second embodiment is provided with 19 electrode units 12. A flexible printed circuit board 11A electrically arranges these 19 electrode units 12 into four rows and five columns. Three rows each have five electrode units 12, and the remaining row has four electrode units 12. The electrode sheet 10A includes four grounding lines 18 and five dual-purpose signal lines 19. Each grounding line 18 is used to ground the ground terminal 14-1 of each temperature sensor 14 in each electrode unit 12 in the same row group. Each dual-purpose signal line 19 short-circuits the dielectric element 15 of each electrode unit 12 and the signal terminal 14-2 of each temperature sensor 14 in each column group, respectively, for receiving temperature detection signals or transmitting AC signals. The four grounding lines 18 of the electrode sheet 10A include a first grounding line 18-1, a second grounding line 18-2, a third grounding line 18-3, and a fourth grounding line 18-4. 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 12-19. Specifically, first grounding line 18-1 is used to ground the ground terminals 14-1 of the temperature sensors 14 of the five electrode units 12 in the first row group, namely, electrode units 12-1 to 12-5. Second grounding line 18-2 is used to ground the ground terminals 14-1 of the temperature sensors 14 of the five electrode units 12 in the second row group, namely, electrode units 12-6 to 12-10.

Fourth grounding line 18-4 is used to ground the ground terminals 14-1 of the temperature sensors 14 of the four electrode units 12 in the fourth row group, namely, electrode units 12-16 to 12-19. In short, each grounding line 18 short-circuits the ground terminals 14-1 of the temperature sensors 14 of all electrode units 12 in each row group and grounds them.

One end of the first dual-purpose signal line 19-1 is simultaneously connected to the dielectric elements 15 of the four electrode units 12, namely, electrode unit 12-1, electrode unit 12-6, electrode unit 12-11, and electrode unit 12-16, and the signal end 14-2 of the temperature sensor 14 of each; one end of the second dual-purpose signal line 19-2 is simultaneously connected to the dielectric elements 15 of the four electrode units 12, namely, electrode unit 12-2, electrode unit 12-7, electrode unit 12-12, and electrode unit 12-17, and the signal end 14-2 of the temperature sensor 14 of each; one end of the third dual-purpose signal line 19-3 is simultaneously connected to the electrode units 12-3, electrode unit 12-8, and electrode unit 12-9. The fourth dual-purpose signal line 19-4 connects the dielectric elements 15 of the four electrode units 12, electrode unit 12-13, and electrode unit 12-18, as well as the signal terminals 14-2 of the temperature sensors 14. One end of the fourth dual-purpose signal line 19-4 is simultaneously connected to the dielectric elements 15 of the four electrode units 12, electrode unit 12-4, electrode unit 12-9, electrode unit 12-14, and electrode unit 12-19, as well as the signal terminals 14-2 of the temperature sensors 14.

In short, each dual-purpose signal line 19 parallel-circuits the dielectric elements 15 of each electrode unit 12 and the signal terminals 14-2 of each temperature sensor 14 in the same column group, and is then used to connect to the adapter 20.

The tumor electric field therapy system formed by the electrode sheet 10A, the adapter 20, and the electric field generator 30 operates in the same manner as the aforementioned tumor electric field therapy system 100. When all grounding switches 25 are disconnected and the input terminals 2 of all bidirectional switches 26 are connected and the acquisition terminals 1 are disconnected, all dual-purpose signal lines 19 and AC signal lines 28 are connected, and all electrode units 12 are connected to the AC signal. When the acquisition terminals 1 of all bidirectional switches 26 are connected and the input terminals 2 are disconnected, the temperature detection signals of the temperature sensors 14 of each electrode unit 12 in each row group are sequentially obtained by sequentially turning on each grounding switch 25.

[0107] As shown in FIG7 , an electrode sheet 10B of the third embodiment includes 17 electrode units 12. A flexible printed circuit board 11B electrically arranges these 17 electrode units 12 into four rows and five columns. Three rows each have five electrode units 12, and the remaining row has two electrode units 12. The electrode sheet 10B includes four grounding lines 18 and five dual-purpose signal lines 19. Each grounding line 18 is used to ground the ground terminal 14-1 of each temperature sensor 14 in each electrode unit 12 in the same row group. Each dual-purpose signal line 19 short-circuits the dielectric element 15 of each electrode unit 12 and the signal terminal 14-2 of each temperature sensor 14 in each column group, respectively, for receiving temperature detection signals or transmitting AC signals.

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 and 12-17. Specifically, first grounding line 18-1 is used to ground the ground terminals 14-1 of the temperature sensors 14 of the five electrode units 12 in the first row group, namely, electrode units 12-1 to 12-5. Second grounding line 18-2 is used to ground the ground terminals 14-1 of the temperature sensors 14 of the five electrode units 12 in the second row group, namely, electrode units 12-6 to 12-10.

The tumor electric field therapy system formed by the electrode sheet 10B, the adapter 20, and the electric field generator 30 operates in the same manner as the aforementioned tumor electric field therapy system 100. When all grounding switches 25 are disconnected and the input terminals 2 of all bidirectional switches 26 are connected and the acquisition terminals 1 are disconnected, all dual-purpose signal lines 19 and AC signal lines 28 are connected, and all electrode units 12 are connected to the AC signal.

[0110] Referring to FIG8 , the electrode sheet 10C of the fourth embodiment, like the electrode sheet 10B of the third embodiment, is provided with 17 electrode units 12. However, the specific circuit connection arrangement of each electrode unit 12 is different. The flexible circuit board 11C of the electrode sheet 10C also electrically arranges these 17 electrode units 12 into four rows and five columns, except that one row has five electrode units 12, and the remaining three rows each have four electrode units 12. The electrode sheet 10C includes four grounding wires 18 and five dual-purpose signal wires 19. Each grounding wire 18 is used to ground the ground terminal 14-1 of the temperature sensor 14 of each electrode unit 12 in the same row group.

One end of the fourth dual-purpose signal line 19-4 is simultaneously connected to the dielectric elements 15 of the four electrode units 12 (electrode unit 12-4, electrode unit 12-9, electrode unit 12-13, and electrode unit 12-17) and the signal terminals 14-2 of their respective temperature sensors 14. One end of the fifth dual-purpose signal line 19-5 is connected to the dielectric element 15 of one electrode unit 12 (electrode unit 12-5) and the signal terminal 14-2 of its temperature sensor 14. In short, each dual-purpose signal line 19 parallel-circuits the dielectric elements 15 and the signal terminals 14-2 of their respective temperature sensors 14 of each electrode unit 12 in the same column group and is used to connect to the adapter 20.

This embodiment differs from the tumor therapy field system 100 described in FIG1 in that this embodiment utilizes the electrode sheet 10D of the fifth embodiment, which is electrically connected to the adapter 20 and electric field generator 30 shown in FIG1 . This embodiment also includes four electrode sheets 10D, each plugging into the first socket 42 of the adapter 20 via a first plug 41D located at the end of a respective first cable 13D. Each electrode sheet 10D similarly includes a plurality of electrode units 12D arranged axially symmetrically and in a centrally aligned arrangement, a plurality of connecting portions 111D located between adjacent electrode units 12, and a connection portion 112D electrically connected to the first cable 13D. However, the connection portion 112D extends from an electrode unit 12 toward the outside of the electrode array (not numbered) and is disposed perpendicularly to a connecting portion 111D. The first cable 13D has eight conductors.

[0114] The electrode units 12D of the electrode sheet 10D have the same structure as the electrode units 12 in the aforementioned embodiment, the only difference being that the number of electrode units 12 in this embodiment is 13, and they are spatially arranged in five rows and five columns. Specifically, the first and last rows each have two electrode units 12, located in the second and fourth columns, respectively; each of the three middle rows has three electrode units 12, and the three electrode units 12 in each row are located in the first, third, and fifth columns, respectively. There are three electrode units 12 located in the center of the electrode array (unnumbered), namely, the three electrode units 12 located in the second row and third column, the third row and third column, and the third row and third column. The rest are electrode units 12 located on the periphery of the electrode array (unnumbered). Adjacent electrode units 12 in the periphery are connected by connecting portions 111D. The electrode units 12 in the second row and third column are connected to the electrode units 12 in the first and second rows and adjacent thereto via connecting portions 111D. The electrode units 12 in the fourth row and third column are connected to the electrode units 12 in the fourth and fifth rows and adjacent thereto via connecting portions 111D. The electrode units 12 in the third row and third column are also connected to the electrode units 12 adjacent thereto in the row and column directions via connecting portions 111D. The electrode units 12 in the periphery are connected in pairs via connecting portions 111D to form an octagonal ring structure.

[0115] Figure 10(A) is a modified embodiment of the electrode sheet 10D shown in Figure 9. The electrode units 12D' of the electrode sheet 10D' in this embodiment are the same in spatial arrangement as the electrode units 12D of the electrode sheet 10D shown in Figure 9, and the setting of the connecting portion 111D' connected to the electrode unit 12D' located in the center is also the same. The only difference is that: in the electrode sheet 10D' in this modified embodiment, two adjacent electrode units 12D' partially located on the periphery are connected by the connecting portion 111D'; and two adjacent electrode units 12D' partially located on the periphery are disconnected and no connecting portion 111D' is provided. Specifically, the two electrode units 12D' in the first row are arranged in a disconnected state, the two electrode units 12D' in the last row are arranged in a disconnected state, the two electrode units 12D' in the first column of the second row and the second column of the first row are arranged in a disconnected state, the two electrode units 12D' in the first column of the third row and the first column of the fourth row are arranged in a disconnected state, the two electrode units 12D' in the fifth column of the second row and the fifth column of the third row are arranged in a disconnected state, and the two electrode units 12D' in the fifth column of the fourth row and the fourth column of the fifth row are arranged in a disconnected state. A first gap D1' is formed between two electrode units 12D' in adjacent columns that are arranged in a disconnected state, and a second gap D2' is formed between two electrode units 12D' in adjacent rows that are arranged in a disconnected state. The provision of the first gap D1' and the second gap D2' can prevent the electrode sheet 10D' from wrinkling when applied, which would affect the overall attachment effect of the electrode sheet.

The electrode units 12D" of the electrode sheet 10D" in this embodiment are the same as the electrode units 12D of the electrode sheet 10D shown in Figure 9 in terms of spatial arrangement, with the only difference being that: in the electrode sheet 10D" in this modified embodiment, the two electrode units 12D" in the first row are arranged in a disconnected state, the two electrode units 12D" in the last row are arranged in a disconnected state, the two electrode units 12D" in the second row and the first column are arranged in a disconnected state from the two electrode units 12D" in the second row and the third column are arranged in a disconnected state, and the two electrode units 12D' in the fourth row and the third column are arranged in a disconnected state from the two electrode units 12D' in the fourth row and the fifth column are arranged in a disconnected state.

The first bidirectional switch 26-1, the second bidirectional switch 26-2, the third bidirectional switch 26-3, and the fourth bidirectional switch 26-4 of the adapter 20 are electrically connected to the first dual-purpose signal line 19-1, the second dual-purpose signal line 19-2, the third dual-purpose signal line 19-3, and the fourth dual-purpose signal line 19-4, respectively, via the first connector 40G. The fifth bidirectional switch 26-5 is in an idle, disconnected state.

[0133] The tumor therapy field system formed by the electrode sheet 10G, adapter 20, and electric field generator 30 operates in the same manner as the aforementioned tumor therapy field system 100. When all grounding switches 25 are disconnected and the input terminals 2 of all bidirectional switches 26 are connected and the acquisition terminals 1 are disconnected, all dual-purpose signal lines 19 and AC signal lines 28 are connected, and all electrode units 12 receive AC signals. When the acquisition terminals 1 of all bidirectional switches 26 are connected and the input terminals 2 are disconnected, the temperature detection signals of the temperature sensors 14 of each electrode unit 12 in each row group are sequentially obtained by sequentially turning on each grounding switch 25. No operation is required for bidirectional switches 26 that are in an idle and disconnected state.

[0134] As shown in Figures 15 and 16 , the primary difference between the tumor therapy field system 100H of this embodiment and the tumor therapy field system 100 is that the electrode sheet 10H of the ninth embodiment includes nine electrode units 12. These nine electrode units 12 are arranged in an array of three rows and three columns. Electrically, the flexible printed circuit board 11H of the electrode sheet 10H arranges these nine electrode units 12 in two rows and five columns, with one row having five electrode units 12 and the other row having four electrode units 12. The electrode sheet 10H includes two grounding wires 18 and five dual-purpose signal wires 19. Each grounding wire 18 connects the ground terminal 14-1 of the temperature sensor 14 of each electrode unit 12 in the same row group to ground. Each dual-purpose signal wire 19 short-circuits the dielectric element 15 of each electrode unit 12 and the signal terminal 14-2 of each temperature sensor 14 in each column group, respectively, for receiving temperature detection signals or transmitting AC signals. The two grounding wires 18 of the electrode sheet 10H are respectively a first grounding wire 18-1 and a second grounding wire 18-2. In the two row groups of the electrode sheet 10H, the first row group includes electrode units 12-1 to 12-5, and the second row group includes electrode units 12-6 to 12-9. Specifically, the first grounding wire 18-1 is used to ground the grounding terminals 14-1 of the temperature sensors 14 of the electrode units 12-1 to 12-5 in the first row group; the second grounding wire 18-2 is used to ground the grounding terminals 14-1 of the temperature sensors 14 of the electrode units 12-6 to 12-9 in the second row group. In short, each grounding wire 18 short-circuits the grounding terminals 14-1 of the temperature sensors 14 of all electrode units 12 in the corresponding row group and grounds them.

[0135] The five dual-purpose signal lines 19 of the electrode sheet 10H include a first dual-purpose signal line 19 - 1 , a second dual-purpose signal line 19 - 2 , a third dual-purpose signal line 19 - 3 , a fourth dual-purpose signal line 19 - 4 , and a fifth dual-purpose signal line 19 - 5 . One end of the first dual-purpose signal line 19-1 is connected to the dielectric elements 15 of the two electrode units 12, electrode unit 12-1 and electrode unit 12-6, and the signal end 14-2 of the temperature sensor 14 of each; one end of the second dual-purpose signal line 19-2 is connected to the dielectric elements 15 of the two electrode units 12, electrode unit 12-2 and electrode unit 12-7, and the signal end 14-2 of the temperature sensor 14 of each; one end of the third dual-purpose signal line 19-3 is connected to the dielectric elements 15 of the two electrode units 12, electrode unit 12-3 and electrode unit 12-8, and the signal end 14-2 of the temperature sensor 14 of each; one end of the fourth dual-purpose signal line 19-4 is connected to the dielectric elements 15 of the two electrode units 12, electrode unit 12-4 and electrode unit 12-9, and the signal end 14-2 of the temperature sensor 14 of each; one end of the fifth dual-purpose signal line 19-5 is connected to the dielectric element 15 of electrode unit 12-5 and the signal end 14-2 of the temperature sensor 14. In short, each dual-purpose signal line 19 short-circuits the dielectric elements 15 and the signal terminals 14 - 2 of the temperature sensors 14 of the electrode units 12 in the same column group in parallel and is used to connect to the adapter 20 .

[0136] The first grounding switch 25-1 and the second grounding switch 25-2 of the adapter 20 are electrically connected to the first grounding line 18-1 and the second grounding line 18-2 of the electrode sheet 10H, respectively, via the first connector 40H. The third grounding switch 25-3 and the fourth grounding switch 25-4 are in an idle and disconnected state. 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 of the adapter 20 are electrically connected to the first dual-purpose signal line 19-1, the second dual-purpose signal line 19-2, the third dual-purpose signal line 19-3, the fourth dual-purpose signal line 19-4, and the fifth dual-purpose signal line 19-5, respectively, via the first connector 40H.

[0137] The tumor therapy field system formed by the electrode sheet 10H, adapter 20, and electric field generator 30 operates in the same manner as the aforementioned tumor therapy field system 100. When all grounding switches 25 are disconnected and the input terminals 2 of all bidirectional switches 26 are connected and the acquisition terminal 1 is disconnected, all dual-purpose signal lines 19 and AC signal lines 28 are connected, and all electrode units 12 receive AC signals. When the acquisition terminals 1 of all bidirectional switches 26 are connected and the input terminals 2 are disconnected, the temperature detection signals from the temperature sensors 14 of each electrode unit 12 in each row group are sequentially connected by turning on each grounding switch 25. No operation is required for grounding switches 25 that are in an idle and disconnected state.

[0138] As shown in FIG17 , the electrode sheet 10J of the tenth embodiment also has nine electrode units 12. Electrically, the flexible printed circuit board 11J of the electrode sheet 10J arranges these nine electrode units 12 into three rows and three columns, with each row having three electrode units 12. The electrode sheet 10J includes three grounding wires 18 and three dual-purpose signal wires 19. Each grounding wire 18 is used to ground the ground terminals 14-1 of the temperature sensors 14 corresponding to each electrode unit 12 in a row. Each dual-purpose signal wire 19 short-circuits the dielectric elements 15 of each electrode unit 12 and the signal terminals 14-2 of each temperature sensor 14 in a column, respectively, for receiving temperature detection signals or transmitting AC signals. The three grounding wires 18 of the electrode sheet 10J are a first grounding wire 18-1, a second grounding wire 18-2, and a third grounding wire 18-3. Of the three row groups of electrode sheet 10J, the first row group includes electrode units 12-1 through 12-3, the second row group includes electrode units 12-4 through 12-6, and the third row group includes electrode units 12-7 through 12-9. Specifically, first grounding wire 18-1 is used to ground the grounding terminals 14-1 of the temperature sensors 14 of electrode units 12-1 through 12-3 in the first row group; second grounding wire 18-2 is used to ground the grounding terminals 14-1 of the temperature sensors 14 of electrode units 12-4 through 12-6 in the second row group; and third grounding wire 18-2 is used to ground the grounding terminals 14-1 of the temperature sensors 14 of electrode units 12-7 through 12-9 in the third row group. In short, each grounding wire 18 short-circuits the grounding terminals 14-1 of the temperature sensors 14 of all electrode units 12 in the corresponding row group and grounds them.

[0139] The three dual-purpose signal lines 19 of the electrode sheet 10J include a first dual-purpose signal line 19-1, a second dual-purpose signal line 19-2, and a third dual-purpose signal line 19-3. One end of the first dual-purpose signal line 19-1 is simultaneously connected to the dielectric elements 15 of the three electrode units 12 (electrode unit 12-1, electrode unit 12-4, and electrode unit 12-7) and the signal end 14-2 of the temperature sensor 14 of each of the three electrode units 12. One end of the second dual-purpose signal line 19-2 is simultaneously connected to the dielectric elements 15 of the three electrode units 12 (electrode unit 12-2, electrode unit 12-5, and electrode unit 12-8) and the signal end 14-2 of the temperature sensor 14 of each of the three electrode units 12. One end of the third dual-purpose signal line 19-3 is simultaneously connected to the dielectric elements 15 of the three electrode units 12 (electrode unit 12-3, electrode unit 12-6, and electrode unit 12-9) and the signal end 14-2 of the temperature sensor 14 of each of the three electrode units 12. In short, each dual-purpose signal line 19 short-circuits the dielectric elements 15 and the signal terminals 14 - 2 of the temperature sensors 14 of the electrode units 12 in the same column group in parallel and is used to connect to the adapter 20 .

[0140] The first grounding switch 25-1, the second grounding switch 25-2, and the third grounding switch 25-3 of the adapter 20 are electrically connected to the first ground line 18-1, the second ground line 18-2, and the third ground line 18-3, respectively, via the first connector 40J. The fourth grounding switch 25-4 is in an idle and disconnected state. The first bidirectional switch 26-1, the second bidirectional switch 26-2, and the third bidirectional switch 26-3 of the adapter 20 are electrically connected to the first dual-purpose signal line 19-1, the second dual-purpose signal line 19-2, and the third dual-purpose signal line 19-3, respectively, via the first connector 40J. The fourth bidirectional switch 26-4 and the fifth bidirectional switch 26-5 are both in an idle and disconnected state.

[0141] The tumor therapy field system formed by the electrode sheet 10J, adapter 20, and electric field generator 30 operates in the same manner as the aforementioned tumor therapy field system 100. When all grounding switches 25 are disconnected and the input terminals 2 of all bidirectional switches 26 are connected and the acquisition terminals 1 are disconnected, all dual-purpose signal lines 19 and AC signal lines 28 are connected, and all electrode units 12 receive AC signals. When the acquisition terminals 1 of all bidirectional switches 26 are connected and the input terminals 2 are disconnected, the temperature detection signals of the temperature sensors 14 of each electrode unit 12 in each row group are sequentially obtained by sequentially turning on each grounding switch 25. No operation is required for grounding switches 25 and bidirectional switches 26 that are in an idle and disconnected state.

[0142] In the tumor electric field therapy system of the present application, the flexible circuit boards (11, 11A, 11B, 11C, 11D, 11E, 11F, 11G, 11H, 11J) of the electrode sheets (10, 10A, 10B, 10C, 10D, 10D', 10D", 10E, 10F, 10G, 10H, 10J) are electrically connected to divide the electrode units 12 into multiple rows and columns, and the ground terminals 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, and the electrode units in the same column are electrically connected to the ground terminals 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. The dielectric elements 15 and signal terminals 14-2 of the respective temperature sensors 14 of the elements 12 are short-circuited and electrically connected to the same dual-purpose signal line 19. The adapter 20 is provided with a plurality of grounding switches 25 and a plurality of bidirectional switches 26. The grounding lines 18 of the electrode sheets (10, 10A, 10B, 10C, 10D, 10D', 10D", 10E, 10F, 10G, 10H, 10J) are electrically connected one by one to the corresponding grounding switches 25, and the dual-purpose signal lines 19 are electrically connected one by one to the corresponding bidirectional switches 26. Among them, the number of grounding switches 25 is greater than or equal to the number of grounding lines 18, and the number of bidirectional switching switches 26 is greater than or equal to the number of dual-purpose signal lines 19. Therefore, the adapter 20 can adapt to a variety of electrode sheets (10, 10A, 10B, 10C, 10D, 10D', 10D", 10E, 10F, 10G, 10H, 10J), which has a grounding switch 25 in an idle disconnected state and / or a bidirectional switching switch 26 in an idle disconnected state.

[0143] In the previous embodiment, the number of grounding switches 25 corresponding to each electrode sheet 10 of the adapter 20 is fixed to 4, and the number of bidirectional switching switches 26 corresponding to each electrode sheet 10 is fixed to 5. This can be applied to a variety of different electrode sheets 10. However, in some usage situations, idle disconnected grounding switches 25 and / or idle disconnected bidirectional switching switches 26 may appear, which makes program control more complicated. Another way is to provide a specific adapter based on the number of grounding wires 18 and the number of dual-purpose signal wires 19 of the electrode sheet to avoid idle disconnected grounding switches 25 and / or idle disconnected bidirectional switching switches 26, thereby facilitating program control. To this end, the present application also provides other embodiments of other electrode sheets and adapters, which will be described separately below.

One end of the second dual-purpose signal line 19-2 is simultaneously connected to the dielectric elements 15 of each of the five electrode units 12 (electrode unit 12-2, electrode unit 12-6, electrode unit 12-10, electrode unit 12-14, and electrode unit 12-18), as well as the signal end 14-2 of each temperature sensor 14. One end of the third dual-purpose signal line 19-3 is simultaneously connected to the dielectric elements 15 of each of the five electrode units 12: electrode unit 12-3, electrode unit 12-7, electrode unit 12-11, electrode unit 12-15, and electrode unit 12-19, as well as the signal end 14-2 of each temperature sensor 14. One end of the fourth dual-purpose signal line 19-4 is simultaneously connected to the dielectric elements 15 of each of the five electrode units 12: electrode unit 12-4, electrode unit 12-8, electrode unit 12-12, electrode unit 12-16, and electrode unit 12-20, as well as the signal end 14-2 of each temperature sensor 14.

[0176] Step 260 : When it is determined that the electrode sheet 10 does not need to be replaced, the AC signal applied to each electrode unit 12 of the electrode sheet 10 is controlled or adjusted according to the temperature detection signal of the temperature sensor 14 of each electrode unit 12 of the electrode sheet 10 .

[0177] Controlling or adjusting the AC signal applied to each electrode unit 12 of the electrode sheet 10 in step 260 also includes:

[0178] Step 261: When the temperature detection signals of the electrode units 12 of the electrode sheet 10 obtained do not exceed the preset temperature threshold, continue to apply the AC signal to the electrode units 12 of the electrode sheet 10; or

[0179] Step 262 : When a temperature detection signal among the acquired temperature detection signals of all the electrode units 12 of the electrode sheet 10 exceeds a preset temperature threshold, stop applying the AC signal to the electrode units 12 of the electrode sheet 10 .

[0180] The stopping of applying the AC signal to the electrode unit 12 of the electrode sheet 10 described in step 262 includes stopping applying the AC signal to all electrode units 12 of the electrode sheet 10, stopping applying the AC signal to the electrode unit 12 in the electrode sheet 10 whose temperature detection signal exceeds the preset temperature threshold, and stopping applying the AC signal to all electrode units 12 in the column where the electrode unit 12 in the electrode sheet 10 whose temperature detection signal exceeds the preset temperature threshold is located.

[0181] When the application of the AC signal to the electrode unit 12 in the electrode sheet 10 whose temperature detection signal exceeds the preset temperature threshold is stopped, the AC signal continues to be applied to the electrode unit 12 in the electrode sheet 10 whose temperature detection signal does not exceed the preset temperature threshold.

[0182] When the application of the AC signal to all electrode units 12 in the column where the electrode unit 12 whose temperature detection signal exceeds the preset temperature threshold in the electrode sheet 10 is located is stopped, the AC signal continues to be applied to all electrode units 12 in the electrode sheet 10 where the temperature detection signal does not exceed the preset temperature threshold and is in a different column from the electrode unit 12 whose temperature detection signal exceeds the preset temperature threshold.

[0184] Step 263: When the temperature detection signal is much lower than the preset temperature threshold, continue to apply the AC signal to each electrode unit 12 of the electrode sheet 10 in a manner of increasing the voltage or current amplitude of the AC signal applied to each electrode unit 12 of the electrode sheet 10 or continue to apply the AC signal to each electrode unit 12 of the electrode sheet 10 in a manner of keeping the voltage or current amplitude of the AC signal applied to each electrode unit 12 of the electrode sheet 10 unchanged; or

[0185] Step 264: When the temperature detection signal approaches a preset temperature threshold, continue to apply the AC signal to each electrode unit 12 of the electrode sheet 10 in a manner that keeps the voltage or current amplitude of the AC signal applied to each electrode unit 12 of the electrode sheet 10 unchanged, or continue to apply the AC signal to each electrode unit 12 of the electrode sheet 10 in a manner that reduces the voltage or current amplitude of the AC signal applied to each electrode unit 12 of the electrode sheet 10.

[0186] Referring to FIG. 36 , the present application further provides a signal control method for tumor electric field therapy, which is used for the electrode sheet 10 described above. The method comprises:

[0187] Step 310: Combine and control the grounding switch 25 and the bidirectional switch 26 electrically connected to the corresponding electrode sheet 10 to apply an AC signal to each electrode unit 12 of the electrode sheet 10 and execute step 320;

[0188] Step 320: Combine and control the grounding switch 25 and the bidirectional switch 26 electrically connected to the electrode sheet 10 to collect temperature detection signals of each electrode unit of the electrode sheet 10 in a row and execute step 330;

[0189] Step 330: Determine the combined control mode of the grounding switch 25 and the bidirectional switch 26 electrically connected to the electrode sheet 10 according to the collected temperature detection signal and execute step 340;

[0190] Step 340 : Control the working state of each electrode unit 12 of the electrode sheet 10 according to the determined combined control mode of the grounding switch 25 and the bidirectional switch 26 .

[0191] The operating states of the electrode units 12 of the electrode sheet 10 described in step 340 include: stopping applying the AC signal and continuing to collect the temperature detection signal, and stopping collecting the temperature detection signal and continuing to apply the AC signal. Continuing to apply the AC signal includes continuing to apply the AC signal in a manner of increasing the voltage or current amplitude of the currently applied AC signal, continuing to apply the AC signal in a manner of maintaining the voltage or current amplitude of the currently applied AC signal, and continuing to apply the AC signal in a manner of decreasing the voltage or current amplitude of the currently applied AC signal.

[0192] The operating state of each electrode unit 12 of the electrode sheet 10 is determined by the temperature detection signal collected by the electrode unit 12. The electrode units 12 of the electrode sheet 10 are divided into different areas. The combination of the grounding switch 25 and the bidirectional switch 26 controls each electrode unit 12 in each area to cyclically switch between applying an AC signal and collecting a temperature detection signal.

[0193] The present embodiment provides another method for detecting the temperature of an electrode sheet for a tumor treatment field system 100. As shown in FIG. 37 , the temperature detection method includes:

[0194] Step 510: disconnect the AC signal input to the electrode sheet 10, perform combination control on the multiple grounding switches 25 and the multiple bidirectional switches 26, and obtain the temperature detection signal of the temperature sensor 14 of the electrode sheet 10 corresponding to each combination in all combinations;

[0195] Step 520: sampling and converting the temperature detection signal detected by each temperature sensor 14 in the electrode sheet 10 to obtain a digital temperature signal;

[0196] Step 530: Transmit the digital temperature signal 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 signal.

[0197] In step 510, “combined control of the plurality of grounding switches 25 and the plurality of bidirectional switches 26” specifically includes:

[0198] Step 511: placing all bidirectional switches 26 at the acquisition terminal 1 to conduct electrical connections between the signal terminals 14 - 2 of the temperature sensors 14 of all electrode units 12 and the corresponding analog-to-digital converters 23 ;

[0199] Step 512: Sequentially and individually closing one of the plurality of grounding switches 25 in a time-sharing manner to collect the temperature detection signals detected by the temperature sensors 14 of the electrode units 12 in the corresponding row group row by row.

[0200] In step 512 , sequentially and time-sharingly closing one of the plurality of grounding switches 25 can connect the detection channels electrically connected between the analog-to-digital converter 23 and each temperature sensor 14 in the row group corresponding to the closed grounding switch 25 .

[0201] In this way, the temperature detection signals of the corresponding temperature sensors 14 in each row group can be obtained in turn, and then after processing by the adapter 20 or the electric field generator 30, the corresponding temperatures of all electrode units 12 on the electrode sheet 10 can be obtained; thereby making the temperature detection of the patient's body surface more comprehensive and accurate.

[0202] For the tumor electric field therapy system 100 of the embodiment of the present application, the temperature of a single electrode unit 12 can also be detected as needed. The specific process of the method for performing temperature detection on a certain electrode unit 12 of the electrode sheet 10 is as follows: disconnect the input of the AC signal, place the bidirectional switch 26 corresponding to the column group where the electrode unit 12 that needs to be individually measured is located at the acquisition end 1, and place the remaining bidirectional switches 26 at the input end 2; at the same time, turn on and ground the ground switch 25 corresponding to the row group where the electrode unit 12 that needs to be individually measured is located, and disconnect all the remaining ground switches 25. In this way, the temperature detection signal of the temperature sensor 14 in the electrode unit 12 that needs to be individually measured can be sampled to obtain the temperature of the electrode unit 12. For example, if the electrode unit 12 that requires independent temperature measurement is electrode unit 12-1, the AC signal switch 35 corresponding to the electric field generator 30 is disconnected, the first bidirectional switch 26-1 corresponding to electrode unit 12-1 is placed at acquisition terminal 1, and the remaining bidirectional switches (second bidirectional switch 26-2, second bidirectional switch 26-3, third bidirectional switch 26-3, and fourth bidirectional switch 26-4) are all placed at input terminal 2. At the same time, the first grounding switch 25-1 corresponding to electrode unit 12-1 is closed and grounded, and the remaining grounding switches (second grounding switch 25-2, third grounding switch 25-3, and fourth grounding switch 25-4) are all disconnected. In this way, the temperature of electrode unit 12-1 can be detected.

[0210] In step 610 , every four adjacent electrode units 12 in the electrode sheet 10 are divided into a region. The four electrode units 12 in each region correspond to a column group and are connected to a dual-purpose signal line 19 corresponding to the same bidirectional switch 26 .

[0211] Step 615: Control the bidirectional switching switch 26 electrically connected to the electrode unit 12 to which an AC signal needs to be applied so that the electrode unit 12 to which an AC signal needs to be applied is electrically connected to the AC signal line 28 to apply the AC signal; at the same time, control the remaining bidirectional switching switches 26 so that 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 is disconnected to stop applying the AC signal.

[0212] In step 615, "electrically connecting the electrode units to which an AC signal needs to be applied to the AC signal line 28 to apply the AC signal and disconnecting the electrical connection between the electrode units 12 in the area where the AC signal does not need to be applied and the AC signal line 28 to stop applying the AC signal" is achieved by placing the bidirectional switching switch 26 electrically connected to the electrode units 12 in the column group corresponding to the area to which the AC signal is to be applied in the electrode sheet 10 at its input end 2, and placing all the bidirectional switching switches 26 electrically connected to the electrode units 12 in the remaining column groups at the collection end 1.

[0213] The first controller 22 or the electric field generator 30 in the adapter 20 of the tumor electric field therapy system 100 of the embodiment of the present application is provided with a preset quantity threshold, a first preset temperature t1, a second preset temperature t2 and a preset temperature threshold t0, wherein the first preset temperature t1 is lower than the second preset temperature t2, and the second preset temperature t2 is lower than the preset temperature threshold t0.
