Description

Technical Field

[0001] The present application relates to Tumor Treating Fields (TTF) technology, and in particular to an electrode array and a tumor treating field system. 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) within the cell. 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 an 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 the existing tumor electric field therapy system, an electric field generator is used to transmit the alternating current signal for tumor electric field therapy to the electrode sheet, and then the alternating electric field is applied to the patient's tumor site through the electrode sheet for tumor electric field therapy. When the tumor treatment electric field is applied to the patient's body, heat will accumulate at the electrode sheet application site, and the temperature of the electrode sheet application site will also increase accordingly. Therefore, it is necessary to monitor the temperature of the electrode sheet application site at all times. When the monitored temperature rises to a certain preset value, it is necessary to adjust the electric field strength applied to the patient's tumor site in a timely manner to avoid excessive temperature at the electrode sheet 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 has multiple electrode units. Even if the same alternating current signal is applied to each electrode unit, the heat generated by each electrode unit will be different due to its different position, that is, the temperature of each electrode unit on the entire electrode sheet will not be completely consistent. In this way, it is possible that the temperature of some electrode units in the entire electrode sheet exceeds 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 separate control on the over-temperature electrode unit. However, for existing electrode sheets, implementing separate control on the electrode units requires that a conductive trace be set for each electrode unit in the substrate of the electrode sheet, which will increase the number of conductive traces in the electrode sheet substrate so that the electrode sheet is not easy to bend, and the cable electrically connected to the electrode sheet will also be thickened, which increases the overall weight of the electrode sheet, which is not conducive to the application of the electrode sheet.

[0006] Therefore, it is necessary to provide an electrode sheet temperature detection method for performing partition control on multiple electrode units using fewer conductive traces. Summary of the invention

[0012] Furthermore, the plurality of electrode units are distributed at intervals in the spatial structure to form a plurality of intervals.

[0013] Furthermore, the interval is located between adjacent branches, and the position between adjacent branches is adjustable.

[0014] Furthermore, the transmission time of the direct current signal and the transmission time of the alternating current signal by the dual-purpose signal line do not overlap each other.

[0015] Furthermore, the electrode unit includes a dielectric element for transmitting an AC signal and a temperature sensor for transmitting a DC signal. The ground terminal of the electrode unit is the ground terminal of the temperature sensor. The signal terminal of the temperature sensor is short-circuited with the dielectric element and serves as the signal input terminal of the electrode unit after short-circuiting.

[0016] Furthermore, the ground wire and the dual-purpose signal wire are both embedded in the connecting portion.

DETAILED DESCRIPTION

[0021] The following embodiments of the technical solution of the present application are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0022] Figure 1 FIG. 1 is a schematic diagram of a tumor electric field treatment system 100 according to an embodiment of the present application. Figure 1 As shown, the tumor electric field treatment 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 signal for tumor treatment and applies the alternating current signal to the electrode sheets 10 through the adapter 20 to generate a therapeutic electric field between the electrode sheets 10 arranged in pairs. The adapter 20 is electrically connected between the electrode sheets 10 and the electric field generator 30, and is used to transmit the alternating current 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 alternating current signal, and the generated alternating current signal is transmitted to each electrode sheet 10 through the adapter 20, so that a therapeutic electric field for treating tumors is generated between the same pair of electrode sheets 10.

[0023] like Figure 1 As shown, 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 plurality 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.

[0024] 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 patient's body surface where the electrode unit 12 is applied. It can be a thermistor element or other temperature sensors other than thermistors, and can be set at any position on the electrode unit 12. The dielectric element 15 is used to apply an alternating current signal to the patient's tumor 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) arranged in the middle to accommodate 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.

[0025] In the first mode, the electrode unit 12 applies an alternating current signal through the dielectric element 15; in the second mode, the temperature sensor 14 is used to detect or collect the temperature of the patient's body surface to which the corresponding electrode unit 12 is attached; in the third mode, the application of the alternating current signal is stopped and the temperature detection and collection are stopped. The first mode, the second mode, and the third mode do not overlap each other in time periods. That is, the time period in which the dielectric element 15 of the electrode unit 12 applies the alternating current signal is staggered and does not overlap with the time period in which the temperature sensor 14 detects the temperature. The electrode unit 12 can switch cyclically between applying an alternating current signal through its dielectric element 15 and detecting the temperature through its temperature sensor 14, that is, the electrode unit 12 can switch cyclically between the first mode and the second mode. The electrode unit 12 can also switch cyclically between the first mode, the second mode, and the third mode, that is, the electrode unit 12 switches cyclically between applying an alternating current signal through the dielectric element 15, collecting or detecting the temperature through the temperature sensor 14, and stopping applying the alternating current signal and collecting the temperature.

[0026] Each electrode sheet 10 includes an electrode array (not numbered) consisting of 20 electrode units 12. The electrode array (not numbered) 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 (not numbered) arranged in four rows and six columns in an interval shape. Specifically, four electrode units 12 are arranged in each of the first and last rows, and six electrode units 12 are arranged in each of the two middle rows. 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 two middle 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.

[0027] The connection portion 111 is only located between two adjacent electrode units 12 arranged in the column direction in each of the third and fourth columns, and between the remaining two adjacent electrode units 12 in the row direction except the two electrode units 12 in the third and fourth columns in each row. That is, the two adjacent electrode units 12 in the third and fourth columns are only connected in the column direction through the connection portion 111, and are disconnected in the row direction and not connected by the connection portion 111; the electrode units 12 in the first, second, fifth and sixth columns are only connected to the electrode units 12 adjacent to them in the row direction through the connection portion 111 arranged in the horizontal direction, and the electrode units 12 adjacent to them in the column direction are disconnected. That is to say, the two adjacent electrode units 12 in the first, second, fifth and sixth columns are disconnected.

[0028] The electrode units 12 located in the third column and the connecting portions 111 located between the electrode units 12 in the column and arranged longitudinally, and the electrode units 12 located in the fourth column and the connecting portions 111 located between the electrode units 12 in the column and also arranged longitudinally all constitute the trunk 114 of the electrode array (not numbered). The connecting portions 111 located on the opposite sides of the electrode units 12 in the third column and the fourth column and connected to the electrode units 12 in the third column and the fourth column respectively through the connecting portions 111 arranged transversely and the electrode units 12 connected to the connecting portions 111 arranged transversely all constitute the branches 115 of the electrode array (not numbered). That is, in this embodiment, the electrode array (not numbered) includes two trunks 114 and a plurality of branches 115 extending laterally from the two trunks 114. Each branch 115 has a free end away from the trunk 114, and the free ends of adjacent branches 115 are arranged in a disconnected state, and the position and distance between adjacent branches 115 can be freely adjusted according to the actual use scenario. Specifically, one trunk 114 is composed of the electrode units 12 located in the third column and the connecting portions 111 located between the adjacent electrode units 12 in the column and arranged in a longitudinal direction, and another trunk 114 is composed of the electrode units 12 located in the fourth column and the connecting portions 111 located between the adjacent electrode units 12 in the column and arranged in a longitudinal direction. The remaining electrode units 12 connected to the trunk 114 through the connecting portions 111 arranged in a transverse direction and the connecting portions 111 arranged in a transverse direction are all branches 115.

[0029] 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 of the third column 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 an 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 an electrode unit 12 located in the fifth column of the fourth row.

[0030] The electrode array (unnumbered) is divided into a symmetrical left part including three columns on the left and a right part including three columns on the right, and the left part and the right part are connected only by a bridge portion 113. The left part 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 part 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 arranged therebetween. Specifically, the two trunks 114 are electrically connected by a bridge portion 113 arranged between a connection portion 111 connecting an electrode unit 12 in the second row of the third column and an electrode unit 12 in the third row of the third column and a connection portion 111 connecting an electrode unit 12 in the second row of the fourth column and an electrode unit 12 in the third row of the fourth column. The connecting portion 111 connecting the electrode unit 12 in the second row of the third column and the electrode unit 12 in the third row of the third column, the connecting portion 111 connecting the electrode unit 12 in the second row of the fourth column and the electrode unit 12 in the third row of the fourth column, and the bridging portion 113 are generally arranged in an "H" shape. In other embodiments, the bridging portion 113 may also be arranged between an electrode unit 12 located in the third column and an electrode unit 12 located in the fourth column. Optionally, the bridging portion 113 is arranged between two electrode units 12 located in the third column and the fourth column and adjacent in the row direction.

[0031] 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. Two adjacent electrode units 12 in the plurality of electrode units 12 located at the periphery that are connected by a 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 electrode units 12 adjacent in the column direction and adjacent in the diagonal direction are all arranged in a disconnected state; some two electrode units 12 adjacent in the row direction are also arranged in a disconnected state; only some two electrode units 12 adjacent 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 electrode units 12 adjacent in the column direction located on the trunk 114 are connected by a longitudinally arranged connection portion 111, and only two electrode units 12 adjacent in the row direction located on the branch 115 are connected by a laterally arranged connection portion 111.

[0032] The electrode array (unnumbered) also has intervals (unnumbered) formed between a number of electrode units 12 distributed at intervals, which can allow moisture on the patient's body surface to escape, heat exchange between the patient's skin and the outside world, or allow the patient's skin to breathe freely, and also allow the positions and spacings between the branches 115 to be freely adjusted, and can also prevent the electrode sheet 10 from wrinkling when applied. The intervals (unnumbered) include a first interval D1 located between the two trunks 114 and a second interval D2 located between the branches 115. The first interval D1 is located between the third column of electrode units 12 and the fourth column of electrode units 12, and the second interval D2 is located between the electrode units 12 in adjacent rows. That is, along the row upward, 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 along the column upward, only the two adjacent electrode units 12 in the third column and the fourth column 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.

[0033] 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 also have different numbers of electrode units 12. In some other embodiments, the 20 electrode units 12 may also be arranged in other ways. Of course, in some other embodiments, the electrode 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.

[0034] Figure 2 The electrode sheet 10' shown is Figure 1 A variation of the electrode sheet 10 shown in the figure has the same spatial structure as 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', 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 interval D2' formed between adjacent rows of electrode units 12'; 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' adjacent to each other in the row direction in the fifth column 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 third row and the fourth column.

[0035] Figure 3 for Figure 1 The diagram shows a circuit connection diagram of the first embodiment of the electrode sheet 10 or its variant embodiment of the electrode sheet 10 ' and the adapter 20 of the first embodiment. It is worth noting that: Figure 3 The arrangement of the electrode units 12 shown is to more clearly illustrate the electrical connection between an electrode sheet 10 and an adapter 20. Figure 3 The arrangement of the electrode units 12 shown does not represent the arrangement of the electrode units 12 in the spatial structure. The following describes the circuit connection by taking the electrode sheet 10 in the first embodiment as an example. Figure 1 as well as Figure 3The 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 has a multi-core wire (not shown) that is electrically connected to the multiple grounding wires 18 and the multiple dual-purpose signal wires 19 of the flexible circuit board 11 in a one-to-one correspondence. 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 wires of the first cable 13 does not exceed 10.

[0036] In this embodiment, each electrode sheet 10 is provided with 20 electrode units 12, and the 20 electrode units 12 are arranged in the order of 1 to 20 in the circuit connection, and are divided into four row groups and five column groups, that is, the 20 electrode units 12 are arranged in four rows and five columns in the circuit connection. The temperature sensor 14 of each electrode unit 12 includes a ground terminal 14-1 and a signal terminal 14-2. The dielectric element 15 and the temperature sensor 14 of each electrode unit 12 are soldered on 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. Since the electrode units 12 are arranged in four rows and five columns in the 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 in the circuit connection, and the multiple dielectric elements 15 are also arranged in four rows and five columns in the circuit connection. It should be noted that the arrangement here is to more clearly show 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. Figure 1 The structure shown is roughly in the form of an array, but may also be other structures, such as petal-shaped or scattered, and may be regular or irregular. 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 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 elements 15 in each electrode unit 12 in the corresponding column group. That is, the dielectric elements 15 in the same column group are short-circuited by the same dual-purpose signal line 19 of the flexible circuit board 11, and the dielectric elements 15 in different column groups are connected in parallel by different dual-purpose signal lines 19 of the flexible circuit board 11. The dual-purpose signal lines 19 of the flexible circuit board 11 are electrically connected to the corresponding wires in the first cable 13 one by one, and then electrically connected to the electric field generator 30 via the adapter 20. That is, the dual-purpose signal lines 19 of the flexible circuit board 11 receive the alternating current signal generated by the electric field generator 30 through the first cable 13 and the adapter 20.

[0037] The multiple grounding wires 18 are respectively arranged in one-to-one correspondence with the multiple row groups of the electrode units 12, and the multiple grounding wires 18 are respectively used to short-circuit the temperature sensor 14 of each electrode unit 12 corresponding to each row group to the ground. That is, the grounding ends 14-1 of the multiple temperature sensors 14 in the same row group are short-circuited through the same grounding wire 18 of the flexible circuit board 11, and the grounding ends 14-1 of the temperature sensors 14 in different row groups are respectively connected to the ground in parallel through different grounding wires 18 of the flexible circuit board 11. During the time period of temperature detection or in the second mode, only one of the multiple grounding wires 18 is turned on at the same time, and the rest are turned off.

[0038] Each of the multiplexed dual-purpose signal lines 19 is also configured to transmit a direct current signal to the temperature sensor 14 in each electrode unit 12 in the corresponding column group to collect and transmit the temperature signal obtained by the detection. The signal ends 14-2 of the multiple temperature sensors 14 located in different column groups are respectively connected in parallel through different dual-purpose signal lines 19 of the flexible circuit board 11, and the signal ends 14-2 of the multiple temperature sensors 14 located in the same column group are short-circuited to the same dual-purpose signal line 19 of the flexible circuit board 11. Specifically, each dual-purpose signal line 19 is configured to short-circuit the signal end 14-2 of the temperature sensor 14 of at most one electrode unit 12 in each row group to an external device for receiving the detection signal, wherein the signal ends 14-2 of the temperature sensors 14 connected to each of the multiplexed dual-purpose signal lines 19 are different from each other to avoid the dual-purpose signal line 19 from outputting duplicate signals later. 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, there is at least one dual-purpose signal line 19 that is not electrically connected to the signal end 14-2 of the temperature sensor 14 of the 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 line 19 of the flexible circuit board 11 receives the DC signal from the adapter 20 or the electric field generator 30 through the first cable 13, and transmits the collected or detected temperature signal to the adapter 20, and then transmits it to the electric field generator 30 through the adapter 20.

[0039] 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 wires of the first cable 13, so as to avoid the cable becoming thicker and the cable becoming harder, thereby increasing the difficulty of fixing the cable; at the same time, the increase in the number of wires of the first cable 13 is avoided to affect 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 may also have other numbers according to the circuit arrangement and quantity differences of the electrode units 12 in different electrode sheets, which will be specifically explained in subsequent embodiments.

[0040] In the tumor electric field therapy system 100, the number of conductive lines electrically connected to the grounding line 18 is related to the number of row groups M of the electrode unit 12, which may be greater than or equal to the number of row groups of the electrode unit 12, and 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 line 19 is related to the number of column groups N of the electrode unit 12, which may be greater than or equal to the number of column groups of the electrode unit 12, and N is a positive integer. The line L embedded in the flexible circuit board 11 of the electrode sheet 10 is equal to the sum of the number of grounding lines 18 and the number of dual-purpose signal lines 19. In the present embodiment, the number of grounding lines 18 is equal to the number of row groups M of the electrode unit 12; the dual-purpose signal line 19 is equal to the number of column groups N of the electrode unit 12.

[0041] exist Figure 3In the illustrated embodiment, the electrode sheet 10 includes four grounding wires 18, each of which is used to ground the grounding ends 14-1 of the temperature sensors 14 in the same row group. The four grounding wires 18 of the electrode sheet 10 are respectively 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. In 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; 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 disconnected, 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 the diode 16 being connected in series with the temperature sensor 14 of the same electrode unit 12 and grounded 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.

[0042] Continue to refer Figure 3As shown, the electrode sheet 10 of this embodiment also includes 5 dual-purpose signal lines 19, one end of each dual-purpose signal line 19 is respectively connected to all electrode units 12 in each column group, and the other end thereof 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 choose to connect to one of the electrode units 12 or not connect to any electrode unit 12 in the row group to avoid the dual-purpose signal line 19 from subsequently outputting duplicate signals. Specifically, the 5 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; 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; one end of the third dual-purpose signal line 19-3 is connected to the electrode unit 12-3, electrode unit 12-8, electrode unit 12-1, and electrode unit 12-2. 3. The dielectric elements 15 of the four electrode units 12 of electrode unit 12-18 and the signal end 14-2 of the temperature sensor 14 of the four electrode units 12; one end of the fourth dual-purpose signal line 19-4 is connected to the dielectric elements 15 of the four electrode units 12 of electrode unit 12-4, electrode unit 12-9, electrode unit 12-14, and electrode unit 12-19 and the signal end 14-2 of the temperature sensor 14 of the four electrode units 12; one end of the fifth dual-purpose signal line 19-5 is connected to the dielectric elements 15 of the four electrode units 12 of electrode unit 12-5, electrode unit 12-10, electrode unit 12-15, and electrode unit 12-20 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 of the electrode units 12 and the signal end 14-2 of the temperature sensor 14 of the same column group in parallel and is used to connect to an external device. It should be noted that these dual-purpose signal lines 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, which will be described in detail below.

[0043] The multiple grounding wires 18 and the multiplexed signal wires 19 are conductive traces embedded in the flexible circuit board 11. The flexible circuit board 11 is electrically connected to the first cable 13. The multiple grounding wires 18 and the multiplexed signal wires 19 embedded in the flexible circuit board 11 are electrically connected to corresponding wires (not shown) in the first cable 13 one by one.

[0044] The tumor electric field treatment 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 sheets 10 via the adapter 20 and the dual-purpose signal line 19 of the electrode sheets 10, and is used to receive the temperature detection signal output by the temperature sensor 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 sheets 10, and is also configured to transmit a DC signal to the dual-purpose signal line 19 of the electrode sheets and receive the temperature detection signal output by the multiple dual-purpose signal line 19 of the electrode sheets 10.

[0045] refer to Figure 3 and Figure 4As shown, the adapter 20 includes: a first controller 22, multiple groups of analog-to-digital converters 23 connected to the first controller 22, multiple groups of pressure resistors 24 corresponding to the multiple groups of analog-to-digital converters 23, multiple groups of grounding switches 25 and multiple groups of two-way switching switches 26, a first communication unit 27, multiple AC signal lines 28 connected to the multiple groups of two-way switching switches 26 in a one-to-one correspondence, and a first power module 29 connected to the first communication unit 27, the first controller 22 and the multiple groups of analog-to-digital converters 23. The first power module 29 provides a DC power supply VCC for each electronic component of the adapter 20. The adapter 20 also includes multiple circuit lines (unnumbered). Among them, the multiple circuit lines (unnumbered) are electrically connected 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 (not labeled) include multiple AC signal lines 28 that transmit AC signals to the corresponding electrode sheets 10 and are electrically connected to the multiplexed signal lines 19 in the flexible circuit board 11 of the corresponding electrode sheets 10, multiple circuit lines (not labeled) that are electrically connected to the multiplexed signal lines 19 in the flexible circuit board 11 of the corresponding electrode sheets 10 and are used to supply power to each temperature sensor 14 of the electrode sheets 10 or transmit the temperature detection signal of the electrode sheets 10, and multiple circuit lines (not labeled) that are electrically connected to the multiple grounding lines 18 in the flexible circuit board 11 of the corresponding electrode sheets 10. The number P of circuit lines electrically connected between the adapter 20 and one electrode sheet 10 is equal to the sum of the number of rows M and the number of columns N of the electrode units 12 of the electrode sheet 10 plus 1; the number H of circuit lines electrically connected between the adapter 20 and 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 groups of the grounding switches 25 and the number of groups of the two-way switching switches 26 are both related to the number of electrode sheets 10. The number of groups of the grounding switches 25 is the same as the number of groups of the two-way switching switches 26; and is not less than the number of electrode sheets 10. Preferably, the number of groups of the grounding switches 25 and the number of groups of the two-way switching switches 26 are both the same as the number of electrode sheets 10. The following is a detailed description of the electrical connection between an electrode sheet 10 having 20 electrode units 12 and an adapter 20 as an example.

[0046] Each group of grounding switches 25 is provided with a plurality of grounding switches 25, which are respectively connected to the adapter 20 and are respectively electrically connected to the circuit lines (not numbered) corresponding to the multi-path grounding lines 18 of the corresponding electrode sheet 10, and are configured to control the conduction or disconnection of the multi-path grounding lines 18. The circuit lines (not numbered) that are electrically connected to the multi-path grounding lines 18 of the electrode sheet 10 are grounded at one end close to the grounding switches 25. The number of grounding switches 25 in each group 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 the two are equal in this embodiment. Figure 3 As shown, in this embodiment, each group of grounding switches 25 is provided with a plurality of 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 plurality of grounding switches 25 in each group respectively control the closing or disconnection of the corresponding grounding wire 18 of a corresponding electrode sheet 10. Specifically, the first grounding switch 25-1 is used to control the closing or disconnection of the first grounding wire 18-1 of the corresponding electrode sheet 10, and further can 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 wire 18-2 of the electrode sheet 10, and further can 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 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 12-11 to electrode unit 12-15 in the third row group of the electrode sheet 10; 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 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 12-16 to electrode unit 12-20 in the fourth row group of the electrode sheet 10. The above-mentioned grounding switch 25 can be a mechanical switch, such as a relay. The grounding switch 25 can also be an electronic switch, and each grounding switch 25 can be opened and closed by the first controller 22 of the adapter 20.

[0047] In this embodiment, the multiple groups of grounding switches 25 are all electronic switches. The first controller 22 is connected to the multiple groups of grounding switches 25 for sequentially and cyclically controlling the opening and closing states of multiple grounding switches 25 in each group of grounding switches 25, and then sequentially and individually conducting each of the multiple grounding wires 18 of the corresponding electrode sheet 10 and cooperating with the switching of the corresponding bidirectional switch 26, so as to sequentially and time-dividedly collect the temperature of the patient's body surface detected by all temperature sensors 14 on the electrode sheet 10. The number of each group of grounding switches 25 is greater than or equal to the number of grounding wires 18 of the flexible circuit board 11 of the corresponding electrode sheet 10. In this embodiment, the number of each group of grounding switches 25 is the same as the number of grounding wires 18 of the corresponding electrode sheet 10.

[0048] Each set of two-way switches 26 is provided with a plurality of two-way switches 26. The plurality of two-way switches 26 in each set are respectively connected to the adapter 20 and are respectively electrically connected to circuit lines (not numbered) corresponding to the multiplex dual-purpose signal lines 19 of the corresponding electrode sheet 10. The number of two-way switches 26 in each set of two-way 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, and 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. Figure 3 In the embodiment shown, the two are equal. Each bidirectional switch 26 has two ends 1 and 2, and the acquisition end 1 of the plurality of bidirectional switches 26 in the same group is electrically connected 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 multiplexed signal line 19 to access the corresponding AC signal line 28 to transmit the 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.

[0049] like Figure 3As shown, taking an electrode sheet 10 electrically connected to an adapter 20 as an example, in this embodiment with 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.

[0058] 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 turned off, 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 in a time-sharing manner.

As for the signal end 14-2 of the temperature sensor 14 of each of the electrode unit 12-16, since only the ground end 14-1 of the temperature sensor 14 of the electrode unit 12-11 is connected to the ground, and the ground ends 14-1 of the temperature sensors 14 of the electrode unit 12-1, the electrode unit 12-6, and the electrode unit 12-16 are 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 located in the third row will not affect the resistance value of the temperature sensor 14 of the electrode unit 12-11, so only the temperature sensor 14 of the electrode unit 12-11 is effectively operated 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 the electrode unit 12-11. Similarly, the voltage value collected on the second detection channel B in the group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-12. The voltage value collected 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 12-13. 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 12-14. 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 12-15.

[0062] 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 two-way switch 26-1, the second two-way switch 26-2, the third two-way switch 26-3, the fourth two-way switch 26-4 and the fifth two-way switch 26-5 are all switched to their respective collection 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 group of analog-to-digital converters 23 short-circuits the temperature sensors of the electrode units 12-1, 12-6, 12-11 and 12-16. Since only the grounding terminal 14-1 of the temperature sensor 14 of the electrode unit 12-16 is connected to the ground, and the grounding terminals 14-1 of the temperature sensors 14 of the electrode unit 12-1, the electrode unit 12-6, and the electrode unit 12-11 are 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 located in the fourth row will not affect the resistance value of the temperature sensor 14 of the electrode unit 12-16. Therefore, only the temperature sensor 14 of the electrode unit 12-16 is effectively operated 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 the electrode unit 12-16. Similarly, the voltage value collected on the second detection channel B in the group of analog-to-digital converters 23 is the voltage value of the temperature sensor 14 of the electrode unit 12-17. The voltage value collected on the third detection channel C 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 collect the temperature detection signals of the temperature sensors 14 of all the 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.

[0063] The first controller 22, the plurality of analog-to-digital converters 23, and the plurality of bidirectional switches 26 can automatically perform operations through pre-programmed program codes. For example, the first controller 22 first controls all the bidirectional switches 26 in the corresponding group of bidirectional switches 26 to switch to the collection end 1 so that the collection ends 1 of the bidirectional switches 26 are all turned on and the input ends 2 are all turned off so that the dual-purpose signal lines 19 of the corresponding electrode sheet 10 are electrically connected to the corresponding group of analog-to-digital converters 23, and then closes the first grounding switch 25-1 in the corresponding group of grounding switches 25, and disconnects 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. During this period, the group Each detection channel A, B, C, D, E of the analog-to-digital converter 23 obtains the temperature detection signal of each temperature sensor 14 of each electrode unit 12 located in the first row group in the corresponding electrode sheet 10 and converts it into a digital signal and stores it in a separately set 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 disconnects 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, E of the group of analog-to-digital converters 23 obtains the temperature detection signal of each temperature sensor 14 of each electrode unit 12 located in the second row group. In this way, each grounding switch 25 in the group of grounding switches 25 is turned on separately in turn, and the temperature detection signal of all the temperature sensors 14 in each row group of the electrode sheet 10 can be obtained. Similarly, the temperature detection signal of all the temperature sensors 14 on at least one pair of electrode sheets 10 is obtained through this operation.

[0064] 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 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 the 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 over-temperature 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 the electrode sheet 10 is used for tumor treatment. 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 end 14-2 of the temperature sensor 14 through the same dual-purpose signal line 19. While it can transmit both AC signals and DC signals for temperature signal collection and collected temperature detection signals 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, reduces the wiring difficulty of the flexible circuit board 11, simplifies the manufacturing process, reduces the weight of the flexible circuit board 11, and reduces the manufacturing cost. The electrode sheet 10 of the present application can also switch between applying AC signals for tumor treatment and transmitting DC signals for temperature collection and transmitting collected temperature detection signals through the combined control of the grounding switch 25 electrically connected to the grounding line 18 arranged thereon and the bidirectional switching switch 26 electrically connected to the dual-purpose signal line 19.

[0065] 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 all the dual-purpose signal lines 19 of the electrode sheet 10 are electrically connected to an AC signal line 28 corresponding to the adapter 20 and 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 far 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 switching switches in a group of bidirectional switching 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 two-way switching switches 26 of a group of two-way switching switches 26 electrically connected to the electrode sheet 10 are all turned on and the input ends 2 are all turned off, 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 two-way switching switch 14 electrically connected to the electrode unit 12 of the electrode sheet 10 to be turned on. The switch 26 is switched 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 whose temperature detection signals of the electrode sheet 10 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, so as to stop applying the AC signal to all the electrode units 12 in the column where the electrode units 12 whose temperature detection signals of the electrode sheet 10 exceed the preset temperature threshold are located, and continue to apply the AC signal to the electrode units 12 in the remaining columns whose temperature detection signals of the electrode sheet 10 do not exceed the preset temperature threshold. In this way, the control method of applying the AC signal of the temperature detection signal to different regions of the tumor electric field treatment system 100 is realized.When an AC signal is applied, all grounding switches 25 are opened.

For other specific structures and working principles of the adapter 20E, please refer to the relevant specific description of the aforementioned adapter 20, which will not be repeated here.

[0131] The first grounding switch 25-1, the second grounding switch 25-2 and the third grounding switch 25-3 on the adapter 20E are electrically connected to the first grounding line 18-1, the second grounding line 18-2 and the third grounding line 18-3 through the first connector 40J'.

Fig.33 The working mode of the tumor electric field therapy system formed by the electrode sheet 10J, the adapter 20E and the electric field generator 30 is the same as that of the aforementioned tumor electric field therapy system 100. When all the grounding switches 25 are disconnected and the input terminals 2 of all the bidirectional switching switches 26 are turned on and the collection terminals 1 are disconnected, all the dual-purpose signal lines 19 and the AC signal lines 28 are turned on, and all the electrode units 12 are connected to the AC signal; when the collection terminals 1 of all the bidirectional switching switches 26 are turned on and the input terminals 2 are disconnected, the temperature detection signals of the temperature sensors 14 of each electrode unit 12 of each row group can be obtained in turn by turning on each grounding switch 25 in turn.

[0132] The present application also provides some temperature detection methods and AC signal application control methods, which are described below using the electrode sheet 10 as an example.

[0133] The present application embodiment provides an electrode sheet temperature detection method, which is applied to the above-mentioned electrode sheet 10 or tumor electric field treatment system 100. Fig.34 As shown, it includes the following steps: Step 210: Control each bidirectional switch 26 electrically connected to each electrode unit 12 of the electrode sheet 10 to disconnect the AC signal applied to the dielectric element 15 of each electrode unit 12 of the electrode sheet 10 and connect the DC signal applied to the signal terminal 14-2 of the temperature sensor 14 of each electrode unit 12 of the electrode sheet 10; Step 220 : Turn on the grounding switches 25 electrically connected to the grounding terminals 14 - 1 of the temperature sensors 14 of the electrode units 12 of the electrode sheet 10 in sequence to obtain temperature detection signals from the temperature sensors 14 of the electrode units 12 of the electrode sheet 10 .

[0134] Step 210 is specifically as follows: controlling the bidirectional switching switch 26 electrically connected to each electrode unit 12 of the electrode sheet 10 to switch from one end electrically connected to the AC signal to one end electrically connected to the DC signal, that is, controlling the bidirectional switching switch 26 electrically connected to the electrode sheet 10 to switch from its input end 2 to its collection end 1; or controlling the bidirectional switching switch 26 electrically connected to each electrode unit 12 of the electrode sheet 10 to switch the dielectric element 15 of each electrode unit 12 of the electrode sheet 10 from the on state to the off state, and at the same time switching the signal end 14-2 of the temperature sensor 14 of each electrode unit 12 of the electrode sheet 10 from the off state to the on state.

[0135] The electrode sheet temperature detection method of the present application can quickly and accurately obtain the temperatures of all electrode units of the electrode sheet; and based on the temperature detection signals of all the temperature sensors of the electrode sheet, it can be judged whether the temperature sensors of the electrode sheet are faulty, whether there is an abnormality, whether the electrode sheet is qualified, and whether it needs to be replaced; it is also possible to judge whether each electrode unit of the electrode sheet is over-temperature based on the temperature detection signals of all the temperature sensors of the electrode sheet when each temperature sensor of the electrode sheet is normal, and then control the alternating current signal applied to the electrode sheet or to each electrode unit of the electrode sheet; it is also possible to identify the type of electrode sheet when there is no abnormality in the temperature detection signals of each temperature sensor of the electrode sheet.

[0136] Ginseng Fig.35 As shown, the embodiment of the present application also provides a method for controlling application of an alternating current signal for tumor electric field therapy, which includes the above steps 210 and 220, and after step 220, further includes: Step 260 : When it is determined that the electrode sheet 10 does not need to be replaced, the alternating current 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 .

[0137] Controlling or adjusting the alternating current signal applied to each electrode unit 12 of the electrode sheet 10 in step 260 also includes: 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 an alternating current signal to the electrode units 12 of the electrode sheet 10; or Step 262 : when there is a temperature detection signal exceeding a preset temperature threshold among the temperature detection signals of all the electrode units 12 of the electrode sheet 10 , stop applying the alternating current signal to the electrode units 12 of the electrode sheet 10 .

[0138] Stopping the application of 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.

[0139] 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.

[0140] When the application of the AC signal to all the 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 the electrode units 12 in the electrode sheet 10 where the temperature detection signal does not exceed the preset temperature threshold and which are in different columns from the electrode unit 12 whose temperature detection signal exceeds the preset temperature threshold.

[0141] The process of continuing to apply the alternating current signal to the electrode sheet 10 in step 261 is specifically as follows: Step 263: When the temperature detection signal is much lower than the preset temperature threshold, the AC signal is continuously applied 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 the AC signal is continuously applied 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 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.

[0142] Ginseng Fig.36 As shown, the present application also provides a signal control method for tumor electric field therapy, which is used for the above-mentioned electrode sheet 10, and the method includes: Step 310: Combining and controlling 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 executing step 320; Step 320: Combining and controlling the grounding switch 25 and the bidirectional switch 26 electrically connected to the electrode sheet 10 to collect the temperature detection signals of the electrode units of the electrode sheet 10 in a row and executing step 330; 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; 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 .

[0143] The working 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 keeping the voltage or current amplitude of the currently applied AC signal unchanged, and continuing to apply the AC signal in a manner of reducing the voltage or current amplitude of the currently applied AC signal.

[0144] The working state of each electrode unit 12 of the electrode sheet 10 is determined by the temperature detection signal collected by the electrode unit 12. Each electrode unit 12 of the electrode sheet 10 is divided into different areas, and each electrode unit 12 in each area can be cyclically switched between applying an AC signal and collecting a temperature detection signal through the combination control of a grounding switch 25 and a bidirectional switch 26.

[0145] The present application embodiment provides another electrode temperature detection method for the tumor electric field treatment system 100, please refer to Fig.37 As shown, the temperature detection method includes: Step 510: disconnect the input of the alternating current signal of the electrode sheet 10, perform combination control on the multiple grounding switches 25 and the multiple bidirectional switching switches 26, and obtain the temperature detection signal of the temperature sensor 14 of the electrode sheet 10 corresponding to each combination in all the combinations; 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; 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.

[0146] In step 510, “combining and controlling the plurality of grounding switches 25 and the plurality of bidirectional switching switches 26” specifically includes: Step 511: placing all the bidirectional switches 26 at the acquisition end 1 to conduct the electrical connection between the signal end 14 - 2 of each temperature sensor 14 of all electrode units 12 and the corresponding analog-to-digital converter 23 ; Step 512: Sequentially and individually close 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.

[0147] In step 512, sequentially and individually closing one of the plurality of grounding switches 25 in a time-sharing manner can turn on the detection channel of the analog-to-digital converter 23 electrically connected to each temperature sensor 14 in the row group corresponding to the closed grounding switch 25 .

[0148] Thus, the temperature detection signals of the corresponding temperature sensors 14 in each row group can be obtained in turn, and then after being processed by the adapter 20 or the electric field generator 30, the corresponding temperatures of all the 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.

[0149] 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 temperature detection of 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 grounding 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 grounding 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, the electrode unit 12 that needs to be individually measured is the electrode unit 12-1. At this time, the corresponding AC signal switch 35 of the electric field generator 30 is disconnected, and the first two-way switch 26-1 corresponding to the electrode unit 12-1 is placed at the collection end 1, and the remaining two-way switches (the second two-way switch 26-2, the second two-way switch 26-3, the third two-way switch 26-3 and the fourth two-way switch 26-4) are all placed at the input end 2; at the same time, the first grounding switch 25-1 corresponding to the electrode unit 12-1 is closed and grounded, and the remaining grounding switches (the second grounding switch 25-2, the third grounding switch 25-3 and the fourth grounding switch 25-4) are all disconnected. In this way, the temperature of the electrode unit 12-1 can be detected.

[0150] The present application also provides another method for applying an alternating current signal for tumor electric field therapy, which is applied to the above-mentioned tumor electric field therapy system 100. Please refer to Fig.38 As shown, the AC signal application method includes: Step 610: determining the area of ​​the electrode unit 12 in the electrode sheet 10 where the alternating current signal needs to be applied; Step 611: Combining and controlling a plurality of grounding switches 25 and a plurality of bidirectional switching switches 26 electrically connected to the electrode sheet 10 to apply an alternating current signal.

[0151] In step 611, “combining and controlling a plurality of grounding switches 25 and a plurality of bidirectional switching switches 26 electrically connected to the electrode sheet 10” is specifically as follows: Step 612: disconnect all grounding switches 25 electrically connected to the electrode sheet 10; Step 613: determining the column group where the electrode units 12 to which the AC signal needs to be applied are located according to the area where the electrode units 12 to which the AC signal needs to be applied are located; Step 614: determining the bidirectional switches 26 electrically connected to the electrode units 12 in the column groups according to the column groups where the electrode units 12 to which the AC signal needs to be applied are located; 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 .

[0152] 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.

[0153] In step 615, "the electrode units to which an AC signal needs to be applied are electrically connected to the AC signal line 28 to apply the AC signal and the electrode units 12 in the area where the AC signal does not need to be applied are electrically disconnected from 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.

[0154] 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.
