Description

Technical Field

[0001] The present application relates to the technical field of tumor electric field therapy, and in particular to an adapter of a tumor electric field therapy system, a tumor electric field therapy system, and a tumor treatment device. Background Art

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

[0003] Compared with traditional cancer treatment methods, tumor electric field therapy has an innovative mechanism of action. Some physiological characteristics of tumor cells, such as geometric shape and high-frequency mitosis, make them susceptible to tumor electric field therapy. Tumor electric field therapy disrupts the normal aggregation of microtubules 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 tumor electric field therapy, the electric field intensity at the cleavage furrow is significantly enhanced, and the charged substances in the cell move toward the cleavage furrow, which interferes with or even destroys the formation of the cell structure, and ultimately leads to cell division failure and apoptosis.

[0004] Related art tumor therapy systems use an electric field application device to transmit alternating electrical signals for tumor therapy to electrodes, which then apply an alternating electric field to the patient's tumor site. When the tumor therapy electric field is applied to the patient's body, it accumulates heat at the application site, causing the temperature to rise accordingly. Therefore, the temperature at the application site must be monitored. If the temperature is too high, the electric field intensity must be adjusted promptly to reduce the risk of skin burns caused by excessive heat.

[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 electrical 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 improve the effect of tumor electric field therapy, it is necessary to implement individual control of the over-temperature electrode units. However, for the electrode sheets in the related art, implementing individual control of the electrode units requires setting 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 difficult to bend, and the cable electrically connected to the electrode sheet will also be thickened, which will increase the overall weight of the electrode sheet, making it difficult to apply the electrode sheet and causing inconvenience to the patient. Summary of the Invention

[0006] The present application aims to solve at least one of the technical problems in the related art to a certain extent. To this end, the first purpose of the present application is to propose an adapter for a tumor electric field therapy system. By multiplexing the dual-purpose signal lines of the corresponding electrode sheet and the linkage between the multiplexing switching unit and the rectifier switching unit corresponding to the electrode sheet, the multiple electrode units of the electrode sheet can be partitioned and controlled using fewer conductive traces, which not only ensures the safety of tumor electric field therapy, but also facilitates the application of the electrode sheet. In addition, the adapter can be customized to precisely adapt to the corresponding type of electrode sheet.

[0070] 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.

[0071] Example 1:

[0072] 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 1As shown, the tumor electric field treatment system 100 includes: at least one pair of electrode sheets 13, an adapter 20 connected to the at least one pair of electrode sheets 13, and an electric field generator 30 connected to the adapter 20. The at least one pair of electrode sheets 13 can be arranged in pairs on the patient's body surface, such as Figure 1 There are four electrode sheets 13 in the apparatus, and every two electrode sheets 13 are arranged as a pair on the patient's body surface. The electric field generator 30 can be used to supply power to at least one pair of electrode sheets 13, so that an alternating electric field for treating tumors is generated between at least one pair of electrode sheets 13. The adapter 20 is electrically connected between at least one pair of electrode sheets 13 and the electric field generator 30, and is used to transmit the alternating electric signal generated by the electric field generator 30 to at least one pair of electrode sheets 13. In other words, the electric field generator 30 is capable of generating an alternating electric signal, and the alternating electric signal generated by the electric field generator 30 is transmitted to each electrode sheet 13 through the adapter 20, so that an alternating electric field for treating tumors is generated between the same pair of electrode sheets 13, so as to apply an alternating electric field to the tumor site of the patient for tumor treatment.

[0073] like Figure 1 As shown, in this embodiment, the number of electrode sheets 13 is 4, and each electrode sheet 13 includes a plurality of electrode units 33 of the same number. Each electrode unit 33 is electrically connected to the adapter 20, and the number of electrode units 33 on each electrode sheet 13 is 20. In other embodiments, the tumor electric field therapy system 100 may also have more or fewer electrode sheets 13; in other embodiments, each pair of electrode sheets 13 has the same number of electrode units 33, and different pairs of electrode sheets 13 may have different numbers of electrode units 33; in other embodiments, the number of electrode units 33 on each electrode sheet 13 may be 9, 13, etc., which can be configured according to actual conditions.

[0074] In this embodiment, the connection line between the two electrode units 33 can be called a connecting strip, and the distance between the electrode units 33 can be adjusted by the connecting strip. If an electrode unit 33 is connected to another electrode unit 33 only by one connecting strip, then the electrode unit 33 is an electrode unit 33 at a free end, for example Figure 1Each electrode sheet 13 shown has nine electrode units 33 at free ends. The space surrounding the electrode units 33 at the free ends is an open space, that is, the electrode units 33 at the free ends have a certain degree of freedom and can move freely in the open space. For example, the connecting belt can be stretched or bent to a certain extent, so that the electrode units 33 can move in all directions. The reason why some electrode units 33 of each electrode sheet 13 are set to be in the form of free ends in this embodiment is that after the electrode sheet is applied to the human body, the electric fields of the electrode units 33 are inconsistent due to the wrinkles of the human skin and the corresponding impedance changes, which leads to inconsistent temperatures of the electrode units 33, and the electrode units 33 located on the periphery of the electrode sheet 13 heat up faster. Therefore, when some electrode units 33 in the electrode sheet 13 are at the free ends, the electrode units 33 at the free ends can be adjusted to increase the heat dissipation space of the peripheral electrode units 33, accelerate heat dissipation, and avoid local excessive temperature causing low-temperature burns to the human body. In addition, the application position of the electrode unit 33 at the free end on the human body can be adjusted, so that the electrode unit 33 at the free end can be flexibly applied to the human body according to actual needs, thereby improving the comfort of the human body and improving the treatment effect.

[0075] Figure 3 for Figure 1 The circuit connection diagram of the electrode sheet 13 and the adapter 20 of the tumor electric field treatment system 100 is shown. Figure 4 Schematic diagram of the structure of the electrode unit 33 is shown. It is worth noting that: Figure 3 The arrangement of the electrode units 33 is shown to more clearly illustrate the electrical connection between an electrode sheet 13 and the adapter 20. Figure 3 The arrangement of the electrode units 33 shown does not represent the arrangement of the electrode units 33 in a spatial structure. Figure 3 The figure shows the cooperation between the rectifier switching unit 16 and the multiplexing switching unit (including multiple bidirectional switches 55) to realize the switching between temperature sampling and applying alternating electrical signals. Figure 3As shown, the multiple electrode units 33 in an electrode sheet 13 are arranged into multiple row groups and multiple column groups. A rectifier switching unit 16 having a first switching terminal 1, a second switching terminal 2, and a fixed terminal 3 is provided for each row group. The first switching terminal 1 of the rectifier switching unit 16 is connected to each temperature detection unit 35 connected in series in the corresponding row group. The second switching terminal 2 of the rectifier switching unit 16 is connected to each electrode unit 33 in the corresponding row group. The fixed terminal 3 of the rectifier switching unit 16 is connected to the multiplexing switching unit via a dual-purpose signal line 19. For example, if terminal 1 of the bidirectional switch 55-1 is turned on and terminal 2 is turned off, and the first switching terminal 1 of the corresponding rectifier switching unit 16 is connected to the fixed terminal 3, the temperature detection signal of the temperature detection unit 35 of the corresponding electrode unit 33 in the electrode sheet 13 can be obtained. Alternatively, if terminal 2 of the bidirectional switch 55-1 is turned on and terminal 1 is turned off, and the second switching terminal 2 of the corresponding rectifier switching unit 16 is connected to the fixed terminal 3, an alternating electrical signal can be applied to each electrode unit 33 in the corresponding row group simultaneously.

[0076] Combine Figure 1 、 Figure 3 as well as Figure 4 The electrode sheet 13 includes: a substrate 31, a plurality of electrode units 33 electrically connected to the substrate 31 at intervals, a plurality of temperature detection units 35, a plurality of rectifier switching units 16, and a first cable 15 electrically connected to the substrate 31. The substrate 31 can be a flexible circuit board. The substrate 31 is embedded with multiple conductive traces, which include multiple grounding wires 18, multiple dual-purpose signal wires 19, and a rectifier ground wire (unnumbered) that grounds the multiple rectifier switching units 16. The first cable 15 has multiple core conductors (not shown), each of which is electrically connected to the multiple grounding wires 18, the multiple dual-purpose signal wires 19, and the rectifier ground wire (unnumbered) of the substrate 31 in a one-to-one correspondence. In this embodiment, the total number of grounding wires 18, dual-purpose signal wires 19, and rectifier ground wires (unnumbered) embedded in the substrate 31 does not exceed 10, so the number of conductors of the first cable 15 does not exceed 10.

[0077] The plurality of electrode units 33 are configured into a plurality of row groups and a plurality of column groups. In the present embodiment, 20 electrode units 33 are provided on each electrode sheet 13, and the 20 electrode units 33 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 33 are arranged in four rows and five columns in the circuit connection. Each electrode unit 33 corresponds to a temperature detection unit 35, and each temperature detection unit 35 has a signal terminal 35-2 and a ground terminal 35-1. The electrode unit 33 and the temperature detection unit 35 are both soldered to the substrate 31. Since the plurality of temperature detection units 35 are arranged in a one-to-one correspondence with the plurality of electrode units 33, the plurality of temperature detection units 35 are also arranged in four row groups and five column groups in the circuit connection. It should be noted that the arrangement here is to more clearly show the electrical connection between the electrode sheet 13 and the adapter 20, and does not represent the arrangement of the electrode unit 33 in the spatial structure. Its spatial structure may be as follows Figure 2 The illustrated structure, which is generally an array, can also be other structures, such as a petal or scattered pattern, and can be regular or irregular. The electrode units 33 are configured to apply an alternating electric field to the patient's tumor site. The temperature detection unit 35 is configured to detect the temperature of the patient's body surface to which the electrode sheet 13 is applied, i.e., the temperature at the corresponding electrode unit 33, and output a temperature detection signal to the adapter 20. In this embodiment, the multiplexed signal lines 19 of the substrate 31 are provided in a one-to-one correspondence with the multiple row groups of electrode units 33. They are configured to transmit the alternating electric signal generated by the electric field generator 30 to each electrode unit 33 in the corresponding row group. That is, the electrode units 33 in the same row group can all be connected to the same dual-purpose signal line 19 of the substrate 31 via the corresponding rectifier switching unit 16, while the electrode units 33 in different row groups are connected in parallel via different dual-purpose signal lines 19 of the substrate 31. The dual-purpose signal lines 19 of the substrate 31 are electrically connected to the first cable 15 and then electrically connected to the electric field generator 30 via the adapter 20. Furthermore, the dual-purpose signal line 19 of the substrate 31 receives the alternating electric signal generated by the electric field generator 30 through the first cable 15 and the adapter 20 .

[0078] Multiple grounding lines 18 are provided in a one-to-one correspondence with the multiple column groups of electrode units 33. The multiple grounding lines 18 are used to sequentially short-circuit each corresponding temperature detection unit 35 in each column group to ground. That is, the ground terminals 35-1 of the multiple temperature detection units 35 in the same column group are short-circuited via the same grounding line 18 on the substrate 31, while the ground terminals 35-1 of the temperature detection units 35 in different column groups are connected in parallel via different grounding lines 18 on the substrate 31. During the temperature detection period, only one of the multiple grounding lines 18 is conductive at any given time; the remaining grounding lines are disconnected. Each temperature detection unit 35 includes a temperature sensor 34, each having a signal terminal 34-2 and a ground terminal 34-1 at its two ends. Multiple temperature sensors 34 in the same row group are connected in series. Signal terminals 34-2 of a temperature sensor 34 at the end of each row group are connected to a dual-purpose signal line 19 via a corresponding rectifier switching unit 16, and then to a DC power supply VCC via a corresponding bidirectional switch 55 and a corresponding voltage divider resistor 53. Ground terminals 34-1 of corresponding temperature sensors 34 in each column group are connected together via corresponding diodes, then connected to a control switch 54 via a corresponding ground line in multiple ground lines 18, and then to a ground pin GND. Tumor therapy field system 100 configures the switching timing of bidirectional switches 55 and control switches 54 to sample the analog temperature signals detected by one or more combinations of all temperature sensors 34 in electrode sheet 13.

[0079] like Figure 3As shown, all temperature sensors 34 in the same row group are connected in series to form a line, which is connected to a dual-purpose signal line 19 (such as one of the dual-purpose signal lines 19-1, 19-2, 19-3, and 19-4) through a corresponding rectifier switching unit 16, and then connected to the DC power supply VCC through a corresponding bidirectional switch 55. The ground terminals 34-1 of all temperature sensors 34 in the same row group are connected to the ground pin GND by five ground lines 18 (such as ground lines 18-1, 18-2, 18-3, 18-4, and 18-5), and the ground terminals 34-1 of all temperature sensors 34 in the same column group are connected to the same ground line 18 (such as ground lines 18-1, 18-2, 18-3, 18-4, and 18-5). In one embodiment, the temperature sensors 34 are connected in series to the DC power supply VCC terminal of each row group. The temperature sensors 34 are connected in series to a bidirectional switch 55 (such as bidirectional switch 55-1, 55-2, 55-3 or 55-4) and a voltage divider resistor 53 (such as voltage divider resistor R1, R2, R3 or R4) at the DC power supply VCC terminal. The voltage divider resistor 53 (such as voltage divider resistor R1, R2, R3 or R4) is closer to the DC power supply VCC terminal than the bidirectional switch 55 (such as bidirectional switch 55-1, 55-2, 55-3 or 55-4). Each ground line 18 is connected in series to a control switch 54 (such as control switch 54-1, 54-2, 54-3, 54-4 or 54-5).

[0080] In this embodiment, when each electrode unit 33 is equipped with a temperature detection unit 35 for temperature detection, the above-mentioned circuit design is used to reduce the number of conductors in the first cable 15, 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 in the first cable 15 affects the adhesion effect between the electrode sheet 13 and the corresponding body surface of the patient's tumor site. The grounding wire 18, dual-purpose signal wire 19 and rectifier ground wire (unnumbered) embedded in the substrate 31 are a total of 10 lines. Specifically, in this embodiment, the grounding wire 18 embedded in the substrate 31 is 5 lines, the dual-purpose signal wire 19 is 4 lines, and the rectifier ground wire (unnumbered) is 1 line. The number of grounding wires 18 is related to the number of column groups N of the electrode unit 33, which is greater than or equal to the number of column groups of the electrode unit 33, and N is a positive integer. The number of dual-purpose signal wires 19 is related to the number of row groups M of the electrode unit 33, which is greater than or equal to the number of row groups of the electrode unit 33, and M is a positive integer. The number of lines L embedded within the substrate 31 of the electrode sheet 13 is equal to the sum of the number of rectifier ground lines (unnumbered), 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 N of column groups of electrode units 33; the number of dual-purpose signal lines 19 is equal to the number M of row groups of electrode units 33.

[0081] The plurality of electrode units 33 are arranged on the substrate 31 in a two-dimensional array. Figure 2As shown, the electrode sheet 13 in this embodiment includes 20 electrode units 33, which are arranged in an array of four rows and six columns. The first and fourth rows each contain four electrode units 33, and the second and third rows each contain six electrode units 33. The four electrode units 33 in each of the first and fourth rows are located in the second to fifth columns, and the six electrode units 33 in each of the second and third rows are located in the first to sixth columns. The five electrode units 33 located in the second and third columns of the first row and the first, second, and third columns of the second row are divided into Region 1. The five electrode units 33 located in the fourth and fifth columns of the first row and the fourth, fifth, and sixth columns of the second row are divided into Region 2. The five electrode units 33 located in the first, second, and third columns of the third row and the second and third columns of the fourth row are divided into Region 3. The five electrode units 33 located in the fourth, fifth, and sixth columns of the third row and the fourth and fifth columns of the fourth row are divided into Region 4. Each region (1-4) corresponds to a row group. In other embodiments, the 20 electrode units 33 may also be arranged in other ways. Of course, in other embodiments, the electrode sheet 13 may also have other numbers of electrode units 33. In short, the implementation of the present application is not limited by the number and arrangement of the electrode units 33 of the electrode sheet 13.

[0082] Each electrode unit 33 can apply an alternating electric signal, and the electrode sheets 13 configured in pairs are used to apply an alternating electric field to the patient's tumor site. Optionally, the electrode unit 33 includes a dielectric element, which can be a ceramic sheet or a polymer dielectric layer composed of a polymer material. Each temperature detection unit 35 is set corresponding to an electrode unit 33 to detect the temperature at the corresponding electrode unit 33. Each temperature detection unit 35 can be set at any position of the corresponding electrode unit 33, such as Figure 3 and Figure 4As shown, in this embodiment, each electrode unit 33 is provided with a through-hole 331 suitable for mounting a temperature detection unit 35. For example, a through-hole 331 is provided through the middle of each electrode unit 33, and a corresponding temperature detection unit 35 is accommodated in the through-hole 331 of each electrode unit 33. Each temperature detection unit 35 includes a temperature sensor 34. The electrode sheet 13 is provided with a diode 36 corresponding to each temperature detection unit 35. The temperature sensor 34 has a signal terminal 34-2 and a ground terminal 34-1. The diode 36 has an anode 36-1 and a cathode 36-2. The anode 36-1 of each diode 36 is connected to the ground terminal 34-1 of the corresponding temperature sensor 34. The cathode 36-2 of the diode 36 corresponding to each column group is connected together and then connected to the ground pin GND through the corresponding control switch 54. Specifically, the anode 36-1 of the diode 36 is connected to the ground terminal 34-1 of the temperature sensor 34, and the cathode 36-2 of the diode 36 is connected to the ground pin GND via a corresponding control switch 54. The ground terminal 34-1 of the temperature sensor 34 serves as the ground terminal 35-1 of the temperature detection unit 35, and the signal terminal 34-2 of the temperature sensor 34 serves as the signal terminal 35-2 of the temperature detection unit 35. The temperature sensor 34 can be a thermistor or other temperature sensor other than a thermistor. Each temperature sensor 34 corresponds to a diode 36, which is connected in series with the temperature sensor 34 of the same electrode unit 33. The diode 36 can prevent reverse current flow, thereby preventing the detection signal from other electrode units 33 from affecting the temperature sensor 34.

[0083] like Figure 3As shown, the electrode sheet 13 of this embodiment includes five grounding wires 18. Each grounding wire 18 is used to ground the ground terminals 35-1 of the temperature detection units 35 in the same column group. The five grounding wires 18 of the electrode sheet 13 are a first grounding wire 18-1, a second grounding wire 18-2, a third grounding wire 18-3, a fourth grounding wire 18-4, and a fifth grounding wire 18-5. Among the five column groups of the electrode sheet 13, the first column group includes electrode unit 33-1, electrode unit 33-6, electrode unit 33-11, and electrode unit 33-16; the second column group includes electrode unit 33-2, electrode unit 33-7, electrode unit 33-12, and electrode unit 33-17; the third column group includes electrode unit 33-3, electrode unit 33-8, electrode unit 33-13, and electrode unit 33-18; the fourth column group includes electrode unit 33-4, electrode unit 33-9, electrode unit 33-14, and electrode unit 33-19; and the fifth column group includes electrode unit 33-5, electrode unit 33-10, electrode unit 33-15, and electrode unit 33-20.Specifically, the first grounding line 18-1 is used to ground the temperature detection units 35 corresponding to the electrode units 33-1, 33-6, 33-11, and 33-16 in the first column group; the second grounding line 18-2 is used to ground the two temperature detection units 35 connected in series between the electrode units 33-1 and 33-2, the two temperature detection units 35 connected in series between the electrode units 33-6 and 33-7, the two temperature detection units 35 connected in series between the electrode units 33-11 and 33-12, and the two temperature detection units 35 connected in series between the electrode units 33-16 and 33-17; and the third grounding line 18-3 is used to ground the three temperature detection units 35 connected in series between the electrode units 33-1 and 33-3, the three temperature detection units 35 connected in series between the electrode units 33-6 and 33-8, and the three temperature detection units 35 connected in series between the electrode units 33-11 and 33-13. , the three temperature detection units 35 connected in series from electrode unit 33-16 to electrode unit 33-18 are grounded; the fourth grounding line 18-4 is used to ground the four temperature detection units 35 connected in series from electrode unit 33-1 to electrode unit 33-4, the four temperature detection units 35 connected in series from electrode unit 33-6 to electrode unit 33-9, the four temperature detection units 35 connected in series from electrode unit 33-11 to electrode unit 33-14, and the four temperature detection units 35 connected in series from electrode unit 33-16 to electrode unit 33-19; the fifth grounding line 18-5 is used to ground the five temperature detection units 35 connected in series from electrode unit 33-1 to electrode unit 33-5, the five temperature detection units 35 connected in series from electrode unit 33-6 to electrode unit 33-10, the five temperature detection units 35 connected in series from electrode unit 33-11 to electrode unit 33-15, and the five temperature detection units 35 connected in series from electrode unit 33-16 to electrode unit 33-20. It should be noted that these grounding lines 18 can be selectively closed or opened, for example, by connecting each grounding line 18 in series with a control switch 54. That is, the grounding terminals 35-1 of the temperature detection units 35 corresponding to the electrode units 33 in each column group are connected to the ground pin GND through a control switch 54. This will be described in detail below. Figure 4 The ground terminal 34-1 of the corresponding temperature sensor 34 in each column group is connected to the anode 36-1 of the corresponding diode 36, and then connected together through the cathode 36-2 of the corresponding diode 36. In short, each ground line 18 short-circuits the ground terminals 35-1 of the temperature detection units 35 corresponding to all electrode units 33 in each column group through the diode 36 and then connects to ground.

[0084] like Figure 3As shown, the electrode sheet 13 of this embodiment also includes four dual-purpose signal lines 19. One end of each dual-purpose signal line 19 is connected to the fixed terminal 3 of the rectifier switching unit 16 corresponding to each row group, and the other end is connected to the adapter 20 for receiving the temperature detection signal and transmitting the alternating electrical signal. Specifically, the four dual-purpose signal lines 19 of the electrode sheet 13 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, and a fourth dual-purpose signal line 19-4. The five electrode units 33, electrode units 33-1 to electrode units 33-5, are respectively connected to the second switching end 2 of the corresponding rectifier switching unit 16, and the temperature detection units 35 corresponding to the five electrode units 33, electrode units 33-1 to electrode units 33-5, are respectively connected in series to the first switching end 1 of the corresponding rectifier switching unit 16; the five electrode units 33, electrode units 33-6 to electrode units 33-10, are respectively connected to the second switching end 2 of the corresponding rectifier switching unit 16, and the temperature detection units 35 corresponding to the five electrode units 33, electrode units 33-6 to electrode units 33-10, are respectively connected to the first switching end 1 of the corresponding rectifier switching unit 16; The five electrode units 33, electrode unit 33-11 through electrode unit 33-15, are respectively connected to the second switching end 2 of the corresponding rectifying switching unit 16, and the temperature detection units 35 corresponding to the five electrode units 33, electrode unit 33-11 through electrode unit 33-15, are connected in series and then connected to the first switching end 1 of the corresponding rectifying switching unit 16. The five electrode units 33, electrode unit 33-16 through electrode unit 33-20, are respectively connected to the second switching end 2 of the corresponding rectifying switching unit 16, and the temperature detection units 35 corresponding to the five electrode units 33, electrode unit 33-16 through electrode unit 33-20, are respectively connected to the first switching end 1 of the corresponding rectifying switching unit 16. In short, each dual-purpose signal line 19 is respectively connected to each electrode unit 33 in the same row group through the corresponding rectifying switching unit 16, and is also connected in series with the temperature detection units 35 corresponding to each electrode unit 33 in the same row group. It should be noted that these dual-purpose signal lines 19 can selectively transmit alternating electrical signals or temperature detection electrical signals, which can be achieved by matching each dual-purpose signal line 19 with the corresponding rectification switching unit 16 and multiplexing switching unit.That is, each temperature detection unit 35 in each row group is connected in series to the corresponding rectifier switching unit 16, and then connected to the multiplexing switching unit through a dual-purpose signal line 19. The multiplexing switching unit includes a plurality of bidirectional switches 55, such as a bidirectional switch 55-1, a bidirectional switch 55-2, a bidirectional switch 55-3, and a bidirectional switch 55-4. Each bidirectional switch 55 has a fixed end (unnumbered) electrically connected to the corresponding dual-purpose signal line 19, an end (i.e., a temperature sampling point) electrically connected to the ADC unit 52 in the adapter 20, and an end (i.e., a temperature sampling point) electrically connected to the alternating power line 57. The multiplexing switching unit is configured to switch the dual-purpose signal line 19 to be connected to the temperature sampling point (unnumbered) or the alternating power line 57, wherein any one of the dual-purpose signal lines 19 is connected to the corresponding temperature sampling point (unnumbered). ), the rectifier switching unit 16 corresponding to the dual-purpose signal line 19 is linked to each other so that the first switching end 1 of the rectifier switching unit 16 corresponding to the dual-purpose signal line 19 is connected to the fixed end 3, and the control switches 54 corresponding to the column groups are closed in sequence, so that the analog temperature signals detected by the temperature detection units 35 in the row group corresponding to the dual-purpose signal line 19 are sampled in sequence based on the corresponding temperature sampling points (unnumbered); when any one of the dual-purpose signal lines 19 is connected to the alternating power line 57, the rectifier switching unit 16 corresponding to the dual-purpose signal line 19 is linked to each other so that the second switching end 2 of the rectifier switching unit 16 corresponding to the dual-purpose signal line 19 is connected to the fixed end 3, so that the alternating electric signal is applied to each electrode unit 33 in the row group corresponding to the dual-purpose signal line 19 based on the alternating power line 57.

The substrate 31 is electrically connected to the first cable 15. The multi-channel ground line 18, the dual-channel signal line 19, and the rectifier ground line (not numbered) embedded in the substrate 31 are each electrically connected to a corresponding conductor (not shown) in the first cable 15.

[0086] The tumor electric field therapy system 100 of this embodiment includes at least one pair of the aforementioned electrode sheets 13, an adapter 20 electrically connected to the electrode sheets 13, and an electric field generator 30 electrically connected to the adapter 20. The adapter 20 is connected between the electrode sheets 13 and the electric field generator 30. The electric field generator 30 provides alternating electrical signals to the multiple electrode units 33 of the electrode sheet 13 via the adapter 20 and the dual-purpose signal line 19 of the electrode sheet 13, or is used to receive temperature detection signals output by the temperature detection units 35 corresponding to the multiple electrode units 33. The adapter 20 transmits the alternating electrical signals generated by the electric field generator 30 to the dual-purpose signal line 19 of the electrode sheet 13, and is also configured to receive the temperature detection signals output by the multiplexed dual-purpose signal line 19 of the electrode sheet 13.

[0087] refer to Figure 3 As shown, the adapter 20 includes: a first controller 51, multiple sets of ADC units 52 connected to the first controller 51, multiple sets of voltage dividers 53 and multiple sets of control switches 54 corresponding to the multiple sets of ADC units 52, multiple sets of bidirectional switches 55 connected to the multiple sets of ADC units 52, a first communication unit 56, an alternating power line 57 connected to each set of bidirectional switches 55, and a first power module 58 connected to the first communication unit 56, the first controller 51, and the multiple sets of ADC units 52. The first power module 58 provides a DC power supply VCC to the various electronic components of the adapter 20. The adapter 20 also includes multiple circuit lines (unnumbered). The multiple circuit lines (unnumbered) are electrically connected to the multiple ground lines 18, the multiplexed signal lines 19, and the rectifier ground line (unnumbered) in the substrate 31 of the corresponding electrode sheet 13 through the first cables 15 of the corresponding electrode sheet 13.

The number L of circuit lines electrically connected between the adapter 20 and an electrode sheet 13 is equal to the sum of the number of rows M and the number of columns N of the electrode units 33 of the electrode sheet 13 plus one; the number H of circuits electrically connected between the adapter 20 and X electrode sheets 13 is equal to X times the number of circuit lines electrically connected to a single electrode sheet 13, that is, H=XL=X*(M+N+1). The number of groups of control switches 54 and the number of groups of bidirectional switching switches are both related to the number of electrode sheets 13. The number of groups of control switches 54 is the same as the number of groups of bidirectional switching switches and is not less than the number of electrode sheets 13. Optionally, the number of groups of control switches 54 and bidirectional switching switches is the same as the number of electrode sheets 13. The following is a detailed description taking only the electrical connection between an electrode sheet 13 having 20 electrode units 33 and the adapter 20 as an example.

[0088] Each group of control switches 54 is provided with a plurality of control switches 54, and the plurality of control switches 54 are respectively connected to the adapter 20 and are respectively electrically connected to the circuit lines (not numbered) corresponding to the multi-way grounding lines 18 of the corresponding electrode sheet 13, and are configured to control the conduction or disconnection between the multi-way grounding lines 18 and the ground pin GND. The circuit lines (not numbered) of the multi-way grounding lines 18 electrically connected to the electrode sheet 13 are grounded at one end close to the control switch 54. The number of control switches 54 in each group of control switches 54 is related to the number of grounding lines 18 of the substrate 31 of the corresponding electrode sheet 13, and the two are equal in this embodiment. Figure 3 As shown, in this embodiment, the plurality of control switches 54 are respectively a first control switch 54-1, a second control switch 54-2, a third control switch 54-3, a fourth control switch 54-4, and a fifth control switch 54-5. The plurality of control switches 54 in the same group all control the closing or opening of the corresponding ground line 18 of the same electrode sheet 13. The first control switch 54-1 is used to control the closing or disconnection of the first grounding line 18-1 of the corresponding electrode sheet 13, and can cooperate with the corresponding group of bidirectional switches 55 and the rectifier switching unit 16 to control the power on and off of each temperature detection unit 35 corresponding to the four electrode units 33 of the first column group of the electrode sheet 13, namely, the electrode unit 33-1, the electrode unit 33-6, the electrode unit 33-11, and the electrode unit 33-16; the second control switch 54-2 is used to control the closing or disconnection of the second grounding line 18-2 of the electrode sheet 13, and can cooperate with the corresponding group of bidirectional switches 55 and the rectifier switching unit 16 to control the multiple electrode units 33 in the first column group and the second column group of the electrode sheet 13 (the multiple electrode units 33 can be respectively: electrode unit 33-1 and electrode unit 33-2, electrode unit 33-6 and electrode unit 33-11, electrode unit 33-16). The third control switch 54-3 is used to control the closing or opening of the third ground line 18-3 of the electrode sheet 13, and can cooperate with the corresponding set of bidirectional switches 55 and the rectifier switching unit 16 to control the powering on and off of each temperature detection unit 35 corresponding to the plurality of electrode units 33 in the first column group, the second column group, and the third column group of the electrode sheet 13 (the plurality of electrode units 33 can be respectively: electrode units 33-1 to 33-3, electrode units 33-6 to 33-8, electrode units 33-11 to 33-13, electrode units 33-16 to 33-18). The same applies to the fourth control switch 54-4 and the fifth control switch 54-5. The above-mentioned control switch 54 can be a mechanical switch, such as a relay. The control switches 54 may also be electronic switches, and each control switch 54 may be switched on and off by an additional first controller 51 .

[0089] In this embodiment, the multiple groups of control switches 54 are all electronic switches. The first controller 51 is in communication with the multiple groups of control switches 54 and is used to sequentially and cyclically control the on and off states of the multiple control switches 54 in each group of control switches 54, thereby sequentially and individually connecting each of the multiple grounding wires 18 of the corresponding electrode sheet 13 and coordinating the switching of the corresponding bidirectional switch 55 and the rectifier switching unit 16 to collect the patient's body surface temperature detected by all temperature detection units 35 on the electrode sheet 13. The number of control switches 54 in each group is not less than the number of grounding wires 18 on the substrate 31 of the corresponding electrode sheet 13. In this embodiment, the number of control switches 54 in each group is the same as the number of grounding wires 18 of the corresponding electrode sheet 13.

[0090] Each multiplexing switching unit is provided with a plurality of bidirectional switches 55. The plurality of bidirectional switches 55 are respectively connected to the adapter 20 and are respectively electrically connected to circuit lines (not numbered) corresponding one-to-one with the multiplexed dual-purpose signal lines 19 of the corresponding electrode sheet 13. The number of bidirectional switches 55 in each multiplexing switching unit is related to the number of dual-purpose signal lines 19 of the substrate 31 of the corresponding electrode sheet 13, and is greater than or equal to the number of dual-purpose signal lines 19 of the substrate 31 of the corresponding electrode sheet 13. In this embodiment, the number of bidirectional switches 55 is equal. Each bidirectional switch 55 has two ends marked 1 and 2. End 1 of the multiple bidirectional switches 55 in the same group is a temperature sampling point, which is electrically connected one by one to the corresponding detection channel of the multiple detection channels of the corresponding group of ADC units 52. Both ends of each bidirectional switch 55 in the same group are electrically connected to the corresponding same alternating power line 57, and are configured to control the multiplexed signal line 19 to connect to the corresponding alternating power line 57 to transmit the alternating electrical signal or to connect to the corresponding detection channel of the corresponding group of ADC units 52 to receive the temperature detection signal output by the temperature detection unit 35.

The second bidirectional switch 55-2 is used to control the switching of the second dual-purpose signal line 19-2 of the corresponding electrode sheet 13 between transmitting the alternating electrical signal and transmitting the temperature detection signal, and thereby cooperates with the rectifier switching unit 16 corresponding to the second row group of the electrode sheet 13 to control the conduction of each electrode unit 33 from the electrode unit 33-6 to the electrode unit 33-10 in the second row group, or to connect the signal end 35-2 of each temperature detection unit 35 corresponding to the electrode unit 33-6 to the electrode unit 33-10 in the second row group, and cooperates with the corresponding control switch 54-1, control switch 54-2, control switch 54-3, control switch 54-4, and control switch 54-5 to enable the second row electrode units 33-6 to the electrode unit 33-10 to transmit the alternating electrical signal to the patient, or to enable the temperature detection signals (such as analog temperature signals) detected by the corresponding one or more combinations of the temperature detection units 35 corresponding to these electrode units 33 to be sampled and output to the corresponding ADC unit 52;The third bidirectional switch 55-3 is used to control the switching between the transmission of the alternating electrical signal and the transmission of the temperature detection signal by the third dual-purpose signal line 19-3 of the corresponding electrode sheet 13, and further cooperates with the rectifier switching unit 16 corresponding to the third row group of the electrode sheet 13 to control the conduction of each electrode unit 33 from the electrode unit 33-11 to the electrode unit 33-15 in the third row group of the electrode sheet 13, or to connect the signal end 35-2 of each temperature detection unit 35 corresponding to the electrode units 33-11 to the electrode units 33-15 in the third row group, and cooperates with the corresponding control switch 54-1, control switch 54-2, control switch 54-3, control switch 54-4, and control switch 54-5 to enable the third row of electrode units 33-11 to the electrode unit 33-15 to transmit the alternating electrical signal to the patient, or to enable the temperature detection signals (such as analog temperature signals) detected by the corresponding one or more combinations of the temperature detection units 35 corresponding to these electrode units 33 to be sampled and output to the corresponding ADC unit 52; The fourth bidirectional switch 55-4 is used to control the switching of the fourth dual-purpose signal line 19-4 of the corresponding electrode sheet 13 between transmitting alternating electrical signals and transmitting temperature detection signals, and then work in conjunction with the rectifier switching unit 16 corresponding to the fourth row group of the electrode sheet 13 to control the conduction of each electrode unit 33 from the electrode unit 33-16 to the electrode unit 33-20 in the fourth row group of the electrode sheet 13, or to conduct with the signal end 35-2 of each temperature detection unit 35 corresponding to the electrode unit 33-16 to the electrode unit 33-20 in the fourth row group, and cooperate with the corresponding control switch 54-1, control switch 54-2, control switch 54-3, control switch 54-4, and control switch 54-5 to enable the fourth row of electrode units 33-16 to the electrode unit 33-20 to transmit alternating electrical signals to the patient or enable the temperature detection signals (such as analog temperature signals) detected by the corresponding one or more combinations of the temperature detection units 35 corresponding to these electrode units 33 to be sampled and output to the corresponding ADC unit 52. When two ends of each set of bidirectional switches are turned on and one end is turned off, and the second switching end 2 of the corresponding rectifier switching unit 16 is connected to the fixed end 3, an alternating electrical signal can be transmitted to each electrode unit 33 in the corresponding row group of the corresponding electrode sheet 13. When each bidirectional switch 55 in each set of bidirectional switches 55 is turned on and two ends are turned off in sequence and in a time-sharing manner, and the two ends of the remaining bidirectional switches 55 are all turned on and one end is all turned off, and the first switching end 1 of the corresponding rectifier switching unit 16 is connected to the fixed end 3, it can cooperate with each control switch 54 in the corresponding set of control switches 54 to transmit the temperature detection signal collected by the temperature detection unit 35 of each electrode unit 33 on the electrode sheet 13 in a time-sharing manner. The above-mentioned bidirectional switch 55 can be a mechanical switch, such as a relay. The bidirectional switch can also be an electronic switch, and each bidirectional switch 55 can be switched by the first controller 51 of the adapter 20.

[0092] In this embodiment, the plurality of sets of bidirectional switches 55 are all electronic switches. The first controller 51 is in communication with the plurality of sets of bidirectional switches 55 and is configured to control the plurality of bidirectional switches 55 in each set of bidirectional switches 55 to switch between their respective terminals 1 and 2, and to coordinate the closing or opening of the corresponding control switch 54 to continuously monitor the patient's body surface temperature detected by all temperature detection units 35 on the electrode sheet 13 or to transmit an alternating electrical signal to the patient.

[0093] In some embodiments of the present application, Figure 3 As shown, the rectifier switching unit 16 includes a rectifier circuit 161 and a controllable switch 162. The rectifier circuit 161 is, for example, a rectifier bridge, which is configured to rectify the alternating current provided by the alternating power line 57 and supply it to the controllable switch 162 when the dual-purpose signal line 19 is connected to the alternating power line 57, so that the second switching end 2 of the rectifier switching unit 16 is connected to the fixed end 3.

[0094] Specifically, rectifier circuit 161 has terminals 1-4. Terminal 1 of rectifier circuit 161 is connected to the dual-purpose signal line 19 corresponding to the corresponding row group electrode unit 33 and terminal 3 of controllable switch 162. Terminals 2 and 4 of rectifier circuit 161 are used to provide power to controllable switch 162. Terminal 3 of rectifier circuit 161 is connected to ground pin GND via a rectifier ground line (unnumbered). Multiple electrode units 33 in the same row group are connected in parallel to terminal 2 of controllable switch 162. Multiple temperature sensors 34 in the same row group are connected in series, and a signal terminal 34-2 at the end of each row group is electrically connected to terminal 1 of controllable switch 162. As an example, controllable switch 162 can be a relay, an electronic switch, or the like.

[0095] Among them, the controllable switch 162 is a normally closed switch, that is, its one end is turned on and connected to the temperature sensor 34 by default. The controllable switch 162 is linked with the corresponding bidirectional switch 55. When the corresponding bidirectional switch 55 is switched to its own one end, the controllable switch 162 is also switched to its own one end, connecting the temperature sensor 34 located in the same row group to the corresponding dual-purpose signal line 19, disconnecting the electrode unit 33 in the corresponding row group from the corresponding dual-purpose signal line 19, and cooperating with the corresponding control switch 54 to open and close to obtain the analog temperature signal detected by the corresponding temperature sensor 34; when the corresponding bidirectional switch 55 is switched to its own two ends, the AC signal is rectified by the rectifier circuit 161 and provides power, which will trigger the controllable switch 162. The controllable switch 162 is also switched to its own two ends, connecting the electrode unit 33 located in the same row group to the corresponding dual-purpose signal line 19, disconnecting the temperature sensor 34 in the corresponding row group from the corresponding dual-purpose signal line 19, and disconnecting all the control switches 54 to transmit the AC signal to the electrode unit 33 of the corresponding row group.

[0096] In this embodiment, each ADC unit 52 is electrically connected to one end of each of the plurality of bidirectional switches 55 in the corresponding multiplexing switching unit via a multi-channel circuit line (not numbered) 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 13, and convert the temperature detection signal from an analog signal to a digital temperature signal. Figure 3 As shown, each ADC unit 52 includes a total of four detection channels A, B, C, and D, namely the first detection channel A, the second detection channel B, the third detection channel C, and the fourth detection channel D. Each detection channel A, B, C, and D is used to connect to a corresponding dual-purpose signal line 19 in the multiple dual-purpose signal lines 19 through a corresponding bidirectional switch 55. Specifically, the first detection channel A is connected to the first dual-purpose signal line 19-1 through terminal 1 of the first bidirectional switch 55-1, the second detection channel B is connected to the second dual-purpose signal line 19-2 through terminal 1 of the second bidirectional switch 55-2, the third detection channel C is connected to the third dual-purpose signal line 19-3 through terminal 1 of the third bidirectional switch 55-3, and the fourth detection channel D is connected to the fourth dual-purpose signal line 19-4 through terminal 1 of the fourth bidirectional switch 55-4. Each detection channel A, B, C, and D is used to receive the temperature detection signal collected by the temperature detection unit 35 corresponding to the electrode unit 33 to which the corresponding dual-purpose signal line 19 is connected. In addition, each detection channel A, B, C, D is connected to a first power module 58 for providing detection voltage to the detection channel A, B, C, D via a corresponding voltage divider resistor 53 in the adapter 20. The first power module 58 provides DC power.

[0097] In this embodiment, the first communication unit 56 is configured to acquire digital temperature signals output by multiple sets of ADC units 52 and transmit the digital temperature signals to the electric field generator 30. The electric field generator 30 is further configured to control and adjust the voltage of the alternating electrical signal provided to the multiple electrode units 33 of the electrode sheet 13 based on the received digital temperature signals. For example, when any of the multiple digital temperature signals received exceeds a preset threshold, indicating that the temperature detected by the temperature detection unit 35 corresponding to at least one electrode unit 33 in the electrode sheet 13 exceeds a preset temperature threshold (e.g., 41°C, 42°C, etc.), the voltage of the alternating electrical signal output by the electric field generator 30 can be appropriately reduced to prevent the electrode units 33 of the electrode sheet 13 from overheating when the alternating electrical signal is applied, thereby preventing low-temperature burns on the patient's skin. The above-mentioned preset temperature threshold and the preset threshold can be determined based on human safety thresholds. The first communication unit 56 is controlled by the first controller 51 and serially transmits the digital temperature signals converted by the multiple sets of ADC units 52. In this embodiment, the preset temperature threshold can be a value within the range of 36°C-45°C.

The second power supply module 32 is also connected to the second controller 37 and the AC signal generator 39, respectively, and provides power to them. The second communication unit 38 is electrically connected to the wire 5 of the second connector 70 via its data receiving line RX and to the wire 6 of the second connector 70 via its data transmitting line TX, thereby enabling information exchange between the electric field generator 30 and the adapter 20.

[0101] The following will refer to Figures 3 to 5The working principle of the tumor electric field treatment system 100 of this embodiment is described in detail.

[0102] Specifically, when it is necessary to detect the temperature of each electrode unit 33 of a certain electrode sheet 13, the second controller 37 of the electric field generator 30 controls the corresponding power supply switch 40 to disconnect the alternating electric signal applied to the electrode sheet 13, and the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 controls one end of a plurality of bidirectional switches 55 of a multiplexing switching unit electrically connected to the electrode sheet 13 to be turned on and the other end to be turned off, and the VCC provided by the first power supply module 58 is used to power the corresponding temperature detection unit 35, and the rectifier switching unit linked to the bidirectional switch 55 is turned on. Terminals 3 and 1 of the controllable switch 162 in element 16 are connected; simultaneously, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 controls each of the control switches 54 in a group electrically connected to the electrode sheet 13 to be turned on in sequence and in a time-sharing manner. At this time, the detection channels of the multiple detection channels of the ADC units 52 corresponding to the electrode sheet 13, which are connected to terminal 1 of the bidirectional switch 55, can sequentially sample the combined temperature detection signals detected by the first temperature detection unit 35 or multiple temperature detection units 35 in the corresponding row group. The temperature detection signals can be represented by voltage values. Of the five control switches 54 in the group corresponding to the electrode sheet 13, only one can be turned on at a time; the other four are turned off. Only one of the four bidirectional switches 55 in the multiplexing switching unit corresponding to the group of ADC units 52 is switched to its end 1, and the rest are switched to its end 2, so that one of the dual-purpose signal lines 19 of the electrode sheet 13 is electrically connected to a detection channel (A, B, C or D) of the corresponding ADC unit 52 and is turned on. With this arrangement, the group of ADC units 52 can collect the voltage value of the first temperature detection unit 35 in the same row group that is short-circuited with the ground line 18 corresponding to the turned-on control switch 54, or the voltage value of the first and second temperature detection units 35 in series, or the voltage value of the first to third temperature detection units 35 in series, or the voltage value of the first to fourth temperature detection units 35 in series, or the voltage value of the first to fifth temperature detection units 35 in series.

[0103] Furthermore, when the first control switch 54-1 is closed, the second control switch 54-2, the third control switch 54-3, the fourth control switch 54-4 and the fifth control switch 54-5 are all opened, and the first bidirectional switch 55-1 is switched to its 1 end, the second bidirectional switch 55-2, the third bidirectional switch 55-3 and the fourth bidirectional switch 55-4 are all switched to their respective 2 ends, and the first switching end 1 of the rectifier switching unit 16 corresponding to the first row group is connected to the fixed end 3, the temperature detection unit 35 corresponding to the electrode unit 33-1 is energized, and the temperature detection units 35 corresponding to the remaining electrode units 33 are de-energized, and the signal end 35-2 of the temperature detection unit 35 corresponding to the electrode unit 33-1 is short-circuited on the first detection channel A in the group of ADC units 52. Since only the electrode unit 33-1 is connected to the fixed end 3, the temperature detection unit 35 corresponding to the electrode unit 33-1 is energized. The grounding terminal 35-1 of the temperature detection unit 35 corresponding to the unit 33-1 is connected to the ground, while the grounding terminals 35-1 of the temperature detection units 35 corresponding to the electrode units 33-2, 33-3, 33-4 and 33-5 are disconnected, and each temperature detection unit 35 (including the temperature sensor 34) is connected in series with the corresponding diode 36, which will not affect the resistance value of the temperature detection unit 35 corresponding to the electrode unit 33-1. Therefore, only the temperature detection unit 35 corresponding to the electrode unit 33-1 is effectively operating on the first detection channel A of the ADC unit 52 group, and the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-1, thereby realizing accurate temperature detection at the electrode unit 33-1.

[0104] When the second control switch 54-2 is closed, the first control switch 54-1, the third control switch 54-3, the fourth control switch 54-4 and the fifth control switch 54-5 are all opened, and the first bidirectional switch 55-1 is switched to its 1 end, the second bidirectional switch 55-2, the third bidirectional switch 55-3 and the fourth bidirectional switch 55-4 are all switched to their respective 2 ends, and the first switching end 1 of the rectifier switching unit 16 corresponding to the first row group is connected to the fixed end 3, the temperature detection units 35 corresponding to the electrode unit 33-1 and the electrode unit 33-2 are connected in series and energized, and the temperature detection units 35 corresponding to the remaining electrode units 33 are de-energized, and the signal end 35-2 of the temperature detection unit 35 corresponding to the electrode unit 33-1 is short-circuited on the first detection channel A of the ADC unit 52 in this group, and the temperature detection units 35 corresponding to the electrode unit 33-1 and the electrode unit 33-2 are connected in series. Since only the temperature detection unit 35 corresponding to the electrode unit 33-2 is The ground terminal 35-1 is connected to the ground, while the ground terminals 35-1 of the temperature detection units 35 corresponding to the electrode units 33-3, 33-4, and 33-5 are disconnected, and each temperature detection unit 35 (including the temperature sensor 34) is connected in series with the corresponding diode 36, which will not affect the resistance of the temperature detection units 35 corresponding to the electrode unit 33-1 and the electrode unit 33-2. Therefore, only the temperature detection units 35 corresponding to the electrode unit 33-1 and the electrode unit 33-2 are effectively operating on the first detection channel A of the group of ADC units 52. The temperature detection signal (voltage value) collected by the first detection channel A is the sum of the voltage values ​​of the temperature detection units 35 corresponding to the electrode unit 33-1 and the electrode unit 33-2. The voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-1 is subtracted to obtain the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-2, thereby realizing accurate temperature detection at the electrode unit 33-2.

[0105] Similarly, when the third control switch 54-3 is closed, the first control switch 54-1, the second control switch 54-2, the fourth control switch 54-4 and the fifth control switch 54-5 are all opened, and the first bidirectional switch 55-1 is switched to its end 1, the second bidirectional switch 55-2, the third bidirectional switch 55-3 and the fourth bidirectional switch 55-4 are all switched to their respective ends 2, and the first switching end 1 of the rectifier switching unit 16 corresponding to the first row group is connected to the fixed end 3, what is detected on the first detection channel A of the group of ADC units 52 is the sum of the voltage values ​​of the electrode unit 33-1, the electrode unit 33-2 and the temperature detection unit 35 corresponding to the electrode unit 33-3. By subtracting the sum of the voltage values ​​of the temperature detection unit 35 corresponding to the electrode unit 33-1 and the electrode unit 33-2, the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-3 can be obtained, thereby achieving accurate temperature detection at the electrode unit 33-3.

[0106] By analogy, when the fourth control switch 54-4 is closed, the first control switch 54-1, the second control switch 54-2, the third control switch 54-3 and the fifth control switch 54-5 are all opened, and the first bidirectional switch 55-1 is switched to its 1 end, the second bidirectional switch 55-2, the third bidirectional switch 55-3 and the fourth bidirectional switch 55-4 are all switched to their respective 2 ends, and the first switching end 1 of the rectifier switching unit 16 corresponding to the first row group is connected to the fixed end 3, the temperature at the electrode unit 33-4 can be accurately controlled. Detection; when the fifth control switch 54-5 is closed, the first control switch 54-1, the second control switch 54-2, the third control switch 54-3 and the fourth control switch 54-4 are all disconnected, and the first bidirectional switching switch 55-1 is switched to its 1 end, the second bidirectional switching switch 55-2, the third bidirectional switching switch 55-3 and the fourth bidirectional switching switch 55-4 are all switched to their respective 2 ends, and the first switching end 1 of the rectifier switching unit 16 corresponding to the first row group is connected to the fixed end 3, accurate detection of the temperature at the electrode unit 33-5 can be achieved.

[0107] Thus, the temperature detection signals at the respective electrode units 33 in the first row group can be collected in sequence through the first detection channel A.

[0108] Similarly, when the first control switch 54-1 is closed, the second control switch 54-2, the third control switch 54-3, the fourth control switch 54-4 and the fifth control switch 54-5 are all opened, and the second bidirectional switch 55-2 is switched to its 1 end, the first bidirectional switch 55-1, the third bidirectional switch 55-3 and the fourth bidirectional switch 55-4 are all switched to their respective 2 ends, and the first switching end 1 of the rectifier switching unit 16 corresponding to the second row group is connected to the fixed end 3, the temperature detection unit 35 corresponding to the electrode unit 33-6 is energized, and the temperature detection units 35 corresponding to the remaining electrode units 33 are de-energized, and the signal end 35-2 of the temperature detection unit 35 corresponding to the electrode unit 33-6 is short-circuited on the second detection channel B in the group of ADC units 52. Since only the electrode unit 33-6 is connected, the temperature detection unit 35 corresponding to the electrode unit 33-6 is energized. The grounding terminal 35-1 of the temperature detection unit 35 corresponding to the electrode unit 33-6 is connected to the ground, while the grounding terminals 35-1 of the temperature detection units 35 corresponding to the electrode unit 33-7, the electrode unit 33-8, the electrode unit 33-9 and the electrode unit 33-10 are disconnected, and each temperature detection unit 35 (including the temperature sensor 34) is connected in series with the corresponding diode 36, which will not affect the resistance value of the temperature detection unit 35 corresponding to the electrode unit 33-6. Therefore, on the second detection channel B of the group of ADC units 52, only the temperature detection unit 35 corresponding to the electrode unit 33-6 is effectively operating, and the temperature detection signal (voltage value) collected by the second detection channel B is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-6, thereby realizing accurate temperature detection at the electrode unit 33-6.

[0109] When the second control switch 54-2 is closed, the first control switch 54-1, the third control switch 54-3, the fourth control switch 54-4 and the fifth control switch 54-5 are all opened, and the second bidirectional switch 55-2 is switched to its 1 end, the first bidirectional switch 55-1, the third bidirectional switch 55-3 and the fourth bidirectional switch 55-4 are all switched to their respective 2 ends, and the first switching end 1 of the rectifier switching unit 16 corresponding to the second row group is connected to the fixed end 3, the temperature detection units 35 corresponding to the electrode unit 33-6 and the electrode unit 33-7 are connected in series and energized, and the temperature detection units 35 corresponding to the remaining electrode units 33 are de-energized, and the signal end 35-2 of the temperature detection unit 35 corresponding to the electrode unit 33-6 is short-circuited on the second detection channel B in the group of ADC units 52, and the temperature detection units 35 corresponding to the electrode unit 33-6 and the electrode unit 33-7 are connected in series. Since only the temperature detection unit 35 corresponding to the electrode unit 33-7 is The ground terminal 35-1 is connected to the ground, while the ground terminals 35-1 of the temperature detection units corresponding to the electrode units 33-8, 33-9, and 33-10 are disconnected, and each temperature detection unit 35 (including the temperature sensor 34) is connected in series with the corresponding diode 36, which will not affect the resistance of the temperature detection units 35 corresponding to the electrode units 33-6 and 33-7. Therefore, only the temperature detection units 35 corresponding to the electrode units 33-6 and 33-7 are effectively operating on the second detection channel B of the group of ADC units 52. The temperature detection signal (voltage value) collected by the second detection channel B is the sum of the voltage values ​​of the temperature detection units 35 corresponding to the electrode units 33-6 and 33-7. The voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-6 is subtracted from the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-6, thereby obtaining the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-7, thereby realizing accurate temperature detection at the electrode unit 33-7.

[0110] By analogy, the temperature detection signals at each electrode unit 33 in the second row group can be collected in sequence through the second detection channel B, the temperature detection signals at each electrode unit 33 in the third row group can be collected in sequence through the third detection channel C, and the temperature detection signals at each electrode unit 33 in the fourth row group can be collected in sequence through the fourth detection channel D.

[0111] Thus, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 can collect the temperature detection signals of the temperature detection units 35 corresponding to all electrode units 33 of a certain electrode sheet 13 by controlling a group of bidirectional switches 55 and a group of control switches 54 that are electrically connected to the electrode sheet 13, as well as the rectifier switching unit 16 that is linked to the group of bidirectional switches 55. Similarly, the temperature detection signals of the temperature sensors 34 of the electrode units 33 of other electrode sheets 13 can be obtained.

[0112] The first controller 51 or the second controller 37, the multiple groups of ADC units 52 and the multiple groups of bidirectional switches 55 can automatically perform operations through pre-programmed program codes. For example, the first controller 51 or the second controller 37 first controls one of the corresponding group of bidirectional switches 55 to switch to end 1 so that end 1 of the bidirectional switch 55 is conductive and end 2 is disconnected, so that the corresponding dual-purpose signal line 19 of the corresponding electrode sheet 13 is electrically connected to the corresponding group of ADC units 52, and the first switching end 1 of the rectifier switching unit 16 linked to the bidirectional switch 55 is connected to the fixed end 3, and then the control switch 54-1 of the corresponding group of control switches 54 is closed, and the remaining control switches 54-2 to 54-5 of the control switch group 54 are disconnected. During this period, the ADC units 52 of the corresponding group are closed. The corresponding detection channel of the ADC unit 52 obtains the temperature detection signal of the temperature detection unit 35 corresponding to the electrode unit 33 located in the corresponding row group in the corresponding electrode sheet 13, converts it into a digital temperature signal, and stores it in a separately provided memory. Then, after a preset time interval, the first controller 51 or the second controller 37 closes the second control switch 54-2 in the group of control switches 54 and opens the first control switch 54-1, the third control switch 54-3, the fourth control switch 54-4, and the fifth control switch 54-5 in the group of control switches 54. During this period, the corresponding detection channel of the ADC unit 52 obtains the temperature detection signals of the two temperature detection units 35 connected in series. By subtracting the previously obtained temperature detection signal, the temperature detection signal corresponding to the current electrode unit 33 can be obtained. In this way, each control switch 54 in the group of control switches 54 is turned on separately in turn to obtain the temperature detection signals of all temperature detection units 35 on the electrode sheet 13. Similarly, through this operation, the temperature detection signals of all temperature detection units 35 on at least one pair of electrode sheets 13 are obtained.

[0113] It should be noted that, in other embodiments, the multiplexing switching unit is further configured to, when the control switch 54 corresponding to any column group is closed, switch the target dual-purpose signal line 19 to the corresponding temperature sampling point, and link it through the rectifier switching unit 16 corresponding to the target dual-purpose signal line 19, so that the first switching end 1 of the rectifier switching unit 16 corresponding to the target dual-purpose signal line 19 is connected to the fixed end 3, so that the analog temperature signals detected by the corresponding temperature detection units 35 in the column group are sampled respectively.

[0114] Specifically, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 can also control one of the control switches 54 electrically connected to a certain electrode sheet 13 to be closed, and at the same time control each bidirectional switching switch 55 in the multiplexing switching unit to turn on one end in turn, so that the detection channels A, B, C, and D in the group of ADC units 52 are sampled in turn to obtain the temperature detection signals at each electrode unit 33 in the same column group.

[0115] For example, the first control switch 54-1 can be controlled to be closed, and the second control switch 54-2, the third control switch 54-3, the fourth control switch 54-4, and the fifth control switch 54-5 can be controlled to be opened. Then, when only the first bidirectional switch 55-1 is switched to its terminal 1, and the second bidirectional switch 55-2, the third bidirectional switch 55-3, and the fourth bidirectional switch 55-4 are all switched to their respective terminals 2, and the first switching terminal 1 of the rectifier switching unit 16 corresponding to the first row group is connected to the fixed terminal 3, the temperature detection unit 35 corresponding to the electrode unit 33-1 is powered on, and the temperature detection units 35 corresponding to the remaining electrode units 33 are powered off. The signal terminal 35-2 of the temperature detection unit 35 corresponding to the electrode unit 33-1 is short-circuited on the first detection channel A in the group of ADC units 52. Only the grounding terminal 35-1 of the temperature detection unit 35 corresponding to the electrode unit 33-1 is connected to the ground, while the grounding terminals 35-1 of the temperature detection units 35 corresponding to the electrode units 33-2, 33-3, 33-4 and 33-5 are disconnected, and each temperature detection unit 35 (including the temperature sensor 34) is connected in series with the corresponding diode 36, which will not affect the resistance value of the temperature detection unit 35 corresponding to the electrode unit 33-1. Therefore, only the temperature detection unit 35 corresponding to the electrode unit 33-1 is effectively operating on the first detection channel A of the ADC unit 52 group, and the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-1, thereby realizing accurate temperature detection at the electrode unit 33-1.

[0116] When only the second bidirectional switch 55-2 is switched to its 1 end, the first bidirectional switch 55-1, the third bidirectional switch 55-3 and the fourth bidirectional switch 55-4 are all switched to their respective 2 ends, and the first switching end 1 of the rectifier switching unit 16 corresponding to the second row group is connected to the fixed end 3, the temperature detection unit 35 corresponding to the electrode unit 33-6 is powered on, and the temperature detection units 35 corresponding to the remaining electrode units 33 are powered off. The signal end 35-2 of the temperature detection unit 35 corresponding to the electrode unit 33-6 is short-circuited on the second detection channel B in the group of ADC units 52. Since only the ground end 35-1 of the temperature detection unit 35 corresponding to the electrode unit 33-6 is connected to the ground, the power is turned off. The ground terminals 35-1 of the temperature detection units 35 corresponding to the electrode units 33-7, 33-8, 33-9, and 33-10 are all disconnected, and each temperature detection unit 35 (including the temperature sensor 34) is connected in series with the corresponding diode 36, which will not affect the resistance value of the temperature detection unit 35 corresponding to the electrode unit 33-6. Therefore, only the temperature detection unit 35 corresponding to the electrode unit 33-6 is effectively operating on the second detection channel B of the group of ADC units 52, and the temperature detection signal (voltage value) collected by the second detection channel B is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-6, thereby realizing accurate temperature detection at the electrode unit 33-6.

[0117] By analogy, the temperature detection signals of the electrode units 33 of the first column group can be collected in sequence through the detection channels A, B, C, and D in the group of ADC units 52 .

[0118] Next, the second control switch 54-2 can be controlled to be closed first, and the first control switch 54-1, the third control switch 54-3, the fourth control switch 54-4 and the fifth control switch 54-5 are all opened. Then, when only the first bidirectional switch 55-1 is switched to its 1 end, the second bidirectional switch 55-2, the third bidirectional switch 55-3 and the fourth bidirectional switch 55-4 are all switched to their respective 2 ends, and the first switching end 1 of the rectifier switching unit 16 corresponding to the first row group is connected to the fixed end 3, the temperature detection units 35 corresponding to the electrode unit 33-1 and the electrode unit 33-2 are connected in series and energized, and the temperature detection units 35 corresponding to the remaining electrode units 33 are de-energized, and the signal end 35-2 of the temperature detection unit 35 corresponding to the electrode unit 33-1 is short-circuited on the first detection channel A of the group of ADC units 52, and the temperature detection units 35 corresponding to the electrode unit 33-1 and the electrode unit 33-2 are connected in series. Since only the temperature detection units 35 corresponding to the electrode unit 33-2 are connected in series, The ground terminal 35-1 of the unit 35 is connected to the ground, while the ground terminals 35-1 of the temperature detection units 35 corresponding to the electrode units 33-3, 33-4 and 33-5 are disconnected, and each temperature detection unit 35 (including the temperature sensor 34) is connected in series with the corresponding diode 36, which will not affect the resistance of the temperature detection units 35 corresponding to the electrode unit 33-1 and the electrode unit 33-2. Therefore, only the temperature detection units 35 corresponding to the electrode unit 33-1 and the electrode unit 33-2 are effectively operating on the first detection channel A of the group of ADC units 52. The temperature detection signal (voltage value) collected by the first detection channel A is the sum of the voltage values ​​of the temperature detection units 35 corresponding to the electrode unit 33-1 and the electrode unit 33-2. The voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-1 is subtracted to obtain the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-2, thereby realizing accurate temperature detection at the electrode unit 33-2.

[0119] Similarly, when only the second bidirectional switch 55-2 is switched to its terminal 1, the first bidirectional switch 55-1, the third bidirectional switch 55-3 and the fourth bidirectional switch 55-4 are all switched to their respective terminals 2, and the first switching terminal 1 of the rectifier switching unit 16 corresponding to the second row group is connected to the fixed terminal 3, the temperature detection units 35 corresponding to the electrode units 33-6 and 33-7 are connected in series and energized, and the temperature detection units 35 corresponding to the remaining electrode units 33 are de-energized. The signal terminal 35-2 of the temperature detection unit 35 corresponding to the electrode unit 33-6 is short-circuited on the second detection channel B in the group of ADC units 52, and the temperature detection units 35 corresponding to the electrode units 33-6 and 33-7 are connected in series. Since only the ground terminal 35-1 of the temperature detection unit 35 corresponding to the electrode unit 33-7 is connected to the ground, the electrode units 33-8 and 33- 9. The ground terminals 35-1 of the temperature detection units 35 corresponding to the electrode units 33-10 are all disconnected, and each temperature detection unit 35 (including the temperature sensor 34) is connected in series with the corresponding diode 36, which will not affect the resistance values ​​of the temperature detection units 35 corresponding to the electrode units 33-6 and 33-7. Therefore, only the temperature detection units 35 corresponding to the electrode units 33-6 and 33-7 are effectively operating on the second detection channel B of the group of ADC units 52. The temperature detection signal (voltage value) collected by the second detection channel B is the sum of the voltage values ​​of the temperature detection units 35 corresponding to the electrode units 33-6 and 33-7. The voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-6 is subtracted from the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-6, thereby obtaining the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-7, thereby realizing accurate temperature detection at the electrode unit 33-7.

[0120] By analogy, the temperature detection signals of the electrode units 33 of the second column group can be collected in sequence through the detection channels A, B, C, and D in the group of ADC units 52 .

[0121] Similarly, the temperature detection signals of the electrode units 33 of the third column group, the fourth column group, and the fifth column group can be sampled one by one based on the above method.

[0122] Therefore, in the embodiment of the present application, by cooperating with the control switch 54, the bidirectional switching switch 55 and the controllable switch 162 in the rectifier switching unit 16, temperature detection at each electrode unit 33 can be achieved without mutual interference and with high detection accuracy.

[0123] Specifically, when it is necessary to apply an alternating electric signal to each electrode unit 33 of a certain electrode sheet 13, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 controls the two ends of each of the multiple bidirectional switching switches 55 of the multiplexing switching unit electrically connected to the electrode sheet 13 to be turned on and one end to be turned off. At the same time, the second switching end 2 of the corresponding rectifier switching unit 16 is connected to the fixed end 3, and controls a power supply switch 40 electrically connected to the electrode sheet 13 to be turned on. At this time, the second controller 37 of the electric field generator 30 controls the AC signal generator 39 to apply an alternating electric signal to each electrode unit 33 of the electrode sheet 13 through the alternating power line 57, and the voltage or current of the applied alternating electric signal is adjustable. That is, the multiplexing switching unit is further configured to switch the multi-channel target dual-purpose signal line 19 to connect to the alternating power supply line 57, and to operate in conjunction with the rectifying switching unit 16 corresponding to the multi-channel target dual-purpose signal line 19, so that the second switching end 2 of the rectifying switching unit 16 corresponding to the multi-channel target dual-purpose signal line 19 is connected to the fixed end 3, so that each electrode unit 33 in the row group corresponding to the multi-channel target dual-purpose signal line 19 is simultaneously applied with the alternating electrical signal based on the alternating power supply line 57.

[0124] It should be noted that in other embodiments, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 can also control a group of bidirectional switches 55 electrically connected to a certain electrode sheet 13 to apply an alternating electric signal to some of the electrode units 33 of the electrode sheet 13 in the same time period. For example, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 controls the first bidirectional switch 55-1 among the multiple bidirectional switches 55 in the group of bidirectional switches 55 electrically connected to the electrode sheet 13 to turn on two ends and turn off one end, connect the second switching end 2 of the rectifier switching unit 16 linked to the first bidirectional switch 55-1 to the fixed end 3, and control a power supply switch 40 electrically connected to the electrode sheet 13 to turn on. At this time, the second controller 37 of the electric field generator 30 controls the AC signal generator 39 to apply an alternating electric signal to the first row group of electrode units 33-1 to 33-5 of the electrode sheet 13 through the alternating power line 57, and the voltage or current of the applied alternating electric signal is adjustable. That is, the multiplexing switching unit is configured to switch the dual-purpose signal lines 19 corresponding to each row group to be connected to the alternating power line 57, so that the electrode units 33 of each row group are simultaneously applied with an alternating electrical signal based on the alternating power line 57. It should be noted that in other embodiments, the alternating electrical signal can also be applied to the electrode units 33 of two or three row groups simultaneously within the same time period, which will not be further described in detail here.

[0125] It should be noted that in the embodiment of the present application, the control switch 54 electrically connected to each of the multiple grounding lines 18 of the electrode sheet 13 and the bidirectional switch 55 electrically connected to each of the multiple dual-purpose signal lines 19 of the electrode sheet 13 are both provided in the adapter 20. However, in other embodiments, the control switch 54 electrically connected to the grounding line 18 and the bidirectional switch 55 electrically connected to the dual-purpose signal line 19 may also be provided on the electrode sheet 13 or provided in the electric field generator 30, which will not be described in detail here. In addition, the ADC unit 52 provided in the adapter 20 may also be provided in the electric field generator 30 and directly controlled by the second controller 37.

[0126] The tumor electric field therapy system 100 of the present application can realize real-time, comprehensive and accurate monitoring of the temperature of all electrode units 33 on the electrode sheet 13 without increasing the weight of the electrode sheet 13 and without adding additional cores of the first cable 15 electrically connected to the electrode sheet 13, and then determine whether the electrode sheet 13 is qualified based on the obtained temperature detection signal; or determine whether the temperature detection unit 35 of the electrode sheet 13 is faulty or abnormal based on the obtained temperature detection signal, and determine whether the electrode sheet 13 needs to be replaced based on the number of faulty or abnormal temperature detection units 35 obtained; or identify the type of the electrode sheet based on the obtained temperature detection signal if the electrode sheet is qualified; or determine whether the electrode unit 33 of the electrode sheet 13 is overheated based on the obtained temperature detection signal if the electrode sheet is qualified, and then control the alternating electric signal applied to the electrode sheet 13 or the electrode unit 33 of the corresponding row of the electrode sheet 13 to avoid low-temperature burns on the patient's body surface when tumor treatment is performed through the electrode sheet 13. In addition, the substrate 31 of the electrode sheet 13 of the present application can transmit both alternating current signals and direct current signals for temperature signal acquisition through the dual-purpose signal line 19 arranged thereon. The two functions are completely isolated by the multiplexing switching unit and the rectifier switching unit 16. This not only greatly reduces the number of conductive traces (grounding line 18, dual-purpose signal line 19) arranged thereon, reduces the wiring difficulty of the substrate 31, simplifies the manufacturing process, reduces the weight of the substrate 31, and reduces manufacturing costs. The electrode sheet 13 of the present application can also achieve effective switching between applying alternating current signals for tumor treatment and transmitting direct current signals for temperature acquisition and transmitting the acquired temperature detection signals through the combined control of the control switch 54 electrically connected to the grounding line 18 arranged thereon, the bidirectional switching switch 55 electrically connected to the dual-purpose signal line 19, and the rectifier switching unit 16.

[0127] Specifically, when it is necessary to apply an alternating electric signal to the patient through the electrode units 33 of a certain electrode sheet 13, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 controls to disconnect all the control switches 54 in a group of control switches 54 corresponding to the electrode sheet 13, and at the same time controls to switch all the bidirectional switching switches 55 in a group of bidirectional switching switches 55 corresponding to the electrode sheet 13 to their respective two ends, so that one end of these bidirectional switching switches 55 are all disconnected and the two ends are all turned on, so that all the dual-purpose signal lines 19 of the electrode sheet 13 are electrically connected to the adapter 20 and an alternating power line 57 corresponding to the electrode sheet 13, and based on the linkage of each rectifier switching unit 16, the alternating electric signal is transmitted to each electrode unit 33 of the electrode sheet 13. When the digital temperature signal obtained by converting the temperature detection signal of the temperature detection unit 35 corresponding to all the electrode units 33 of the detected electrode sheet 13 is 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 39 through its second controller 37 to continue to generate an alternating electric 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 13 through a corresponding alternating power line 57 of the adapter 20, so that the pair of electrode sheets 13 continue to apply the alternating electric signal; when the digital temperature signal obtained by converting the temperature detection signal of the temperature detection unit 35 corresponding to all the electrode units 33 of the detected electrode sheet 13 is lower than but close to the preset temperature threshold stored in the electric field generator 30 or the adapter 20, the electric field generator 30 can reduce the alternating electric signal generated by the AC signal generator 39 through the second controller 37. The voltage or current of the signal is reduced, thereby reducing the voltage or current of the alternating electric signal applied to the pair of electrode sheets 13; when it is detected that a digital temperature signal obtained by converting the temperature detection signal of the temperature detection unit 35 corresponding to an electrode unit 33 of a certain electrode sheet 13 is greater than a preset temperature threshold, the electric field generator 30 controls the power supply switch 40 electrically connected to the electrode sheet 13 to be disconnected through the second controller 37 to stop applying the alternating electric signal to the electrode sheet 13; or the second controller 37 of the electric field generator 30 or the first controller 51 of the adapter 20 controls all the bidirectional switches 55 in a group of bidirectional switches 55 electrically connected to the electrode sheet 13 to switch from their 2 ends to 1 end, that is, controls all the bidirectional switches 55 in a group of bidirectional switches 55 electrically connected to the electrode sheet 13 to be turned on at their 1 ends and turned off at their 2 ends, thereby stopping applying the alternating electric signal to the electrode sheet 13;Or, when it is detected that a digital temperature signal obtained by converting the temperature detection signal of the temperature detection unit 35 corresponding to an electrode unit 33 of a certain electrode sheet 13 is greater than a preset temperature threshold, the second controller 37 of the electric field generator 30 controls the power switch 40 electrically connected to the electrode sheet 13 to continue to be turned on, and the second controller 37 of the electric field generator 30 or the first controller 51 of the adapter 20 controls a bidirectional switch 55 electrically connected to the electrode unit 33 of the electrode sheet 13 to switch from its 2nd end to its 1st end, and the second controller 37 of the electric field generator 30 or the first controller 51 of the adapter 20 simultaneously controls the bidirectional switch 55 electrically connected to the electrode unit 33 of the electrode sheet 13 to switch from its 2nd end to its 1st end. The remaining bidirectional switches 55 electrically connected to electrode units 33 in different rows from the electrode units 33 whose digital temperature signals, converted from the temperature detection signals, do not exceed the preset temperature threshold, all continue to maintain electrical connection at their respective ends. This stops applying the alternating electrical signal to all electrode units 33 in the row where the digital temperature signals, converted from the temperature detection signals of the electrode sheet 13, exceed the preset temperature threshold, and continues applying the alternating electrical signal to the electrode units 33 in the remaining rows where the digital temperature signals, converted from the temperature detection signals of the electrode sheet 13, do not exceed the preset temperature threshold. This implements a method for controlling the application of alternating electrical signals based on temperature detection signals in the tumor electric field therapy system 100, reliably and efficiently controlling the operation of the tumor electric field therapy system 100 and improving the therapeutic effect.

[0128] The present application embodiment provides an electrode sheet temperature detection method, which is applied to the above-mentioned electrode sheet 13 or tumor electric field treatment system 100, referring to Figure 8 As shown, it includes the following steps:

[0129] Step 210: Control the multiplexing switching unit so that the dual-purpose signal line 19 corresponding to any row group in the corresponding electrode sheet 13 is connected to the corresponding temperature sampling point, wherein the first switching end 1 of the rectifier switching unit 16 corresponding to the row group in the corresponding electrode sheet 13 is connected to the fixed end 3.

[0130] Specifically, the power supply switch 40, the bidirectional switching switch 55 electrically connected to the electrode units 33 of the electrode sheet 13, and the rectification switching unit 16 are controlled to disconnect the alternating electrical signal applied to the electrode units 33 of the electrode sheet 13, and at the same time connect the direct current signal applied to the signal end 35-2 of the temperature detection unit 35 of the electrode unit 33 of the electrode sheet 13.

[0131] Further, the bidirectional switching switch 55 electrically connected to each electrode unit 33 of the electrode sheet 13 is controlled to switch from one end thereof electrically connected to the alternating electrical signal to one end thereof connected to the direct electrical signal, that is, the bidirectional switching switch 55 electrically connected to the electrode sheet 13 is controlled to switch from its 2 end to its 1 end, and at the same time, the rectifier switching unit 16 is switched from the second switching end 2 to the first switching end 1 and connected to the fixed end 3; or, the bidirectional switching switch 55 electrically connected to each electrode unit 33 of the electrode sheet 13 is controlled to switch the electrode unit 33 of each electrode unit 33 of the electrode sheet 13 from the on state to the off state, and at the same time, the signal end 35-2 of the temperature detection unit 35 of each electrode unit 33 of the electrode sheet 13 is switched from the off state to the on state.

[0132] Step 220: Control the control switch 54 corresponding to each column group to sample the analog temperature signal of the corresponding electrode unit based on the corresponding temperature sampling point.

[0133] Specifically, the control switch 54 electrically connected to the ground terminal 35 - 1 of the temperature detection unit 35 of each electrode unit 33 of the electrode sheet 13 is turned on in a time-sequential manner to obtain the temperature detection signal of the temperature detection unit 35 of each electrode unit 33 of the electrode sheet 13 .

[0134] In some embodiments, controlling the control switch 54 corresponding to each column group includes:

[0135] The control switches 54 corresponding to each column group are controlled to be closed in sequence, so as to sample the analog temperature signals detected by the temperature detection units 35 in the row group in sequence based on the corresponding temperature sampling points.

[0136] In some other embodiments, when the control switch 54 corresponding to any one of the column groups is closed, the method further includes:

[0137] The multiplexing switching unit is controlled so that the dual-purpose signal lines 19 corresponding to each row group in the corresponding electrode sheet 13 are connected to the corresponding temperature sampling points in sequence, so that the analog temperature signals detected by each temperature detection unit 35 in the column group are sampled respectively based on the corresponding temperature sampling points.

[0138] The electrode sheet 13 temperature detection method of the present application can quickly and accurately obtain the temperature of all electrode units 35 of the electrode sheet 13; and based on the obtained temperature detection signals of all temperature detection units 35 of the electrode sheet 13, it can be judged whether the temperature detection unit 35 of the electrode sheet is faulty, whether there is an abnormality, or whether the electrode sheet 13 is qualified or needs to be replaced; it can also be judged whether each electrode unit 33 of the electrode sheet 13 is over-temperature based on the obtained temperature detection signals of all temperature detection units 35 of the electrode sheet 13 when each temperature detection unit 35 of the electrode sheet 13 is normal, and then the alternating electric signal applied to the electrode sheet 13 or applied to each electrode unit 33 of the electrode sheet 13 can be controlled to improve the treatment effect; the electrode sheet type can also be identified when there is no abnormality in the temperature detection signals of each temperature detection unit 35 of the electrode sheet 13.

[0139] The first controller 51 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 threshold, a first preset temperature, a second preset temperature and a preset temperature threshold, wherein the first preset temperature is lower than the second preset temperature, and the second preset temperature is lower than the preset temperature threshold.

[0140] Reference Figure 9 As shown, the present application also provides a method for detecting abnormal temperature of an electrode sheet, which includes the following steps:

[0141] Step 210: Control the multiplexing switching unit so that the dual-purpose signal line 19 corresponding to any row group in the corresponding electrode sheet 13 is connected to the corresponding temperature sampling point, wherein the first switching end 1 of the rectifier switching unit 16 corresponding to the row group in the corresponding electrode sheet 13 is connected to the fixed end 3.

[0142] Step 220 : Control the control switches 54 corresponding to each column group to sample the analog temperature signals of the corresponding electrode units 33 based on the corresponding temperature sampling points to determine the temperature detection signals of the respective electrode units 33 in each electrode sheet 13 .

[0143] Step 230: Determine whether the electrode sheet 13 is abnormal based on the temperature detection signal.

[0144] In some embodiments, determining whether the electrode sheet 13 is abnormal according to the temperature detection signal in step 230 specifically includes the following steps:

[0145] Step 231: Compare the temperature of each electrode unit 33 in the corresponding electrode sheet 13 with a preset temperature threshold based on the temperature detection signal. Specifically, the digital temperature signal corresponding to the temperature detection signal detected by the temperature detection unit 35 corresponding to each electrode unit 33 in the electrode sheet 13 can be compared with the preset temperature threshold.

[0146] Step 232: Determine whether the temperature of the electrode sheet 13 is abnormal based on the comparison result. Specifically, determine whether the temperature of each electrode unit 33 in the electrode sheet 13 is abnormal based on the comparison result.

[0147] The comparison results in step 232 include not exceeding the preset temperature threshold and exceeding the preset temperature threshold. Not exceeding the preset temperature threshold includes being far below the preset temperature threshold and being close to the preset temperature threshold. The preset temperature threshold is 40°C-42°C. Optionally, the preset temperature threshold is 40.5°C-41.5°C. Optionally, the preset temperature threshold is 41°C-41.5°C. Optionally, the preset temperature threshold is 41°C.

[0148] The process of determining whether the temperature of the electrode sheet 13 is abnormal based on the comparison result in step 232 is as follows: if the temperature of any electrode unit 33 in the corresponding electrode sheet 13 exceeds a preset temperature threshold, it is determined that the temperature of the electrode sheet 13 is abnormal. If the temperature of all electrode units 33 in the corresponding electrode sheet 13 does not exceed the preset temperature threshold, it is determined that the temperature of the electrode sheet 13 is not abnormal.

[0149] In other embodiments, determining whether the electrode sheet 13 is abnormal according to the temperature detection signal in step 230 specifically includes the following steps:

[0150] Step 233: When it is determined according to the temperature detection signal that any one of the electrode units 33 in the corresponding electrode sheet 13 is abnormal or faulty, the electrode sheet 13 is determined to be unqualified.

[0151] Specifically, based on the temperature detection signals detected by the temperature detection units 35 corresponding to the electrode units 33 in the electrode sheet 13, it is determined whether the temperature detection units 35 corresponding to the electrode units 33 in the electrode sheet 13 have any abnormality or have failed. Then, based on whether the temperature detection units 35 corresponding to the electrode units 33 in the electrode sheet 13 have any abnormality or have failed, it is determined whether the electrode sheet 13 is qualified. When the temperature detection units 35 corresponding to the electrode units 33 in the electrode sheet 13 have any abnormality or have failed, the electrode sheet 13 is determined to be unqualified. When the temperature detection units 35 corresponding to the electrode units 33 in the electrode sheet 13 do not have any abnormality or have not failed, the electrode sheet 13 is determined to be qualified.

[0152] In some other embodiments, determining whether the electrode sheet 13 is abnormal according to the temperature detection signal in step 230 specifically includes the following steps:

[0153] Step 234 : When it is determined based on the temperature detection signal that an abnormal or faulty electrode unit 33 exists in the corresponding electrode sheet 13 , the number of the abnormal or faulty electrode units 33 is determined.

[0154] Step 235: When the number of abnormal or faulty electrode units 33 reaches a preset threshold, it is determined that the electrode sheet 13 needs to be replaced.

[0155] Specifically, based on the temperature detection signals obtained from the temperature detection units 35 corresponding to the electrode units 33 in the electrode sheet 13, it is determined whether there is an abnormality or a fault in the temperature detection units 35 corresponding to the electrode units 33 in the electrode sheet 13; and then, based on whether there is an abnormality or a fault in the temperature detection units 35 corresponding to the electrode units 33 in the electrode sheet 13, it is determined whether the electrode sheet 13 needs to be replaced.

[0156] For example, when the temperature detection unit 35 corresponding to each electrode unit 33 in the electrode sheet 13 is abnormal or faulty, and the number of abnormal or faulty temperature detection units 35 exceeds a preset threshold, the electrode sheet 13 is determined to need to be replaced. When the number of abnormal or faulty temperature detection units 35 in the electrode sheet 13 does not exceed the preset threshold, the electrode sheet 13 is determined not to need to be replaced. The preset threshold is 20% of the total number of all temperature detection units 35 in the electrode sheet 13.

[0157] Reference Figure 10 As shown, the present application also provides a control method for a tumor electric field treatment system, which includes the following steps:

[0158] Step 210: Control the multiplexing switching unit so that the dual-purpose signal line 19 corresponding to any row group in the corresponding electrode sheet 13 is connected to the corresponding temperature sampling point, wherein the first switching end 1 of the rectifier switching unit 16 corresponding to the row group in the corresponding electrode sheet 13 is connected to the fixed end 3.

[0159] Step 220 : Control the control switches 54 corresponding to each column group to sample the analog temperature signals of the corresponding electrode units 33 based on the corresponding temperature sampling points to determine the temperature detection signals of the respective electrode units 33 in each electrode sheet 13 .

[0160] Step 240: Control the intensity of the alternating electric signal applied to the electrode unit 33 according to the temperature detection signal.

[0161] Specifically, when it is determined that the electrode sheet 13 does not need to be replaced, the alternating electrical signal applied to each electrode unit 33 in the electrode sheet 13 is controlled or adjusted based on the temperature detection signal detected by the temperature detection unit 35 corresponding to each electrode unit 33 in the electrode sheet 13. In other words, steps 234-235 can be added between steps 240 and 220.

[0162] In some embodiments, controlling the intensity of the alternating electrical signal applied to the electrode unit 33 according to the temperature detection signal in step 240 specifically includes the following steps:

[0163] Step 241 : Compare the temperature of each electrode unit 33 in the electrode sheet 13 with a preset temperature threshold according to the temperature detection signal.

[0164] Step 242: Control the intensity of the alternating electric signal according to the comparison result.

[0165] In some embodiments, controlling the strength of the alternating electrical signal according to the comparison result in step 242 specifically includes:

[0166] Step 2421: If the temperature of at least one electrode unit 33 exceeds a preset temperature threshold, stop applying the alternating electrical signal to the electrode units 33 of the electrode sheet 13. Specifically, when the temperature detection signals obtained from all electrode units 33 of the electrode sheet 13 indicate that the temperature exceeds the preset temperature threshold, stop applying the alternating electrical signal to the electrode units 33 of the electrode sheet 13. If the temperature detection signals obtained from all electrode units 33 of the electrode sheet 13 do not exceed the preset temperature threshold, continue applying the alternating electrical signal to each electrode unit 33 of the electrode sheet 13.

[0167] In some embodiments, stopping applying the alternating electric signal to the electrode unit 33 of the electrode sheet 13 in step 2421 specifically includes: stopping applying the alternating electric signal to all electrode units 33 of the electrode sheet 13; or stopping applying the alternating electric signal to all electrode units 33 in the row group of the electrode unit 33 in the electrode sheet 13 that exceeds a preset temperature threshold.

[0168] Furthermore, while the application of the alternating electrical signal to all electrode cells 33 in the row group of the electrode cell 33 in the electrode sheet 13 that exceeds the preset temperature threshold is stopped, the alternating electrical signal continues to be applied to the electrode cells 33 in other rows of the electrode sheet 13. The intensity of the alternating electrical signal applied to the electrode cells 33 in other rows of the electrode sheet 13 is adjustable. For example, the alternating electrical signal continues to be applied to all electrode cells 33 in the electrode sheet 13 whose temperature detection signal corresponds to a temperature that does not exceed the preset temperature threshold and which are in a different row from the electrode cell 33 whose temperature detection signal exceeds the preset temperature threshold, and the intensity of the alternating electrical signal is adjustable.

[0169] In other embodiments, controlling the strength of the alternating electrical signal according to the comparison result in step 242 specifically includes:

[0170] Step 2422: When the temperatures at all electrode units 33 in the electrode sheet 13 do not exceed the preset temperature threshold, if the temperatures at all electrode units 33 in the electrode sheet 13 do not exceed the first preset temperature, increase the intensity of the alternating electric signal applied to the electrode units 33 of the electrode sheet 13, wherein the first preset temperature is less than the preset temperature threshold.

[0171] In step 2422, the electric field strengths corresponding to the row groups whose alternating electric signal strengths are increased have the same increase amplitude.

[0172] Step 2423: When the temperatures at all electrode units 33 in the electrode sheet 13 do not exceed the preset temperature threshold, if the temperature at at least one electrode unit 33 in the electrode sheet 13 exceeds the first preset temperature and is less than the preset temperature threshold, the alternating electric signal strength currently applied to the electrode unit 33 of the electrode sheet 13 is maintained unchanged.

[0173] Step 2424: When the temperatures at all electrode units 33 in the electrode sheet 13 do not exceed the preset temperature threshold, if the temperature at at least one electrode unit 33 in the electrode sheet 13 exceeds the second preset temperature and is less than the preset temperature threshold, the intensity of the alternating electric signal applied to the electrode unit 33 of the electrode sheet 13 is reduced, wherein the second preset temperature is greater than the first preset temperature and less than the preset temperature threshold.

[0174] In step 2424, the electric field strength corresponding to each row group whose alternating electric signal strength is reduced has the same reduction amplitude.

[0175] Exemplarily, when the temperature corresponding to the temperature detection signal is far below the preset temperature threshold, the alternating electric signal is continued to be applied to each electrode unit 33 of the electrode sheet 13 in a manner of increasing the voltage or current amplitude of the alternating electric signal applied to each electrode unit 33 of the electrode sheet 13, or the alternating electric signal is continued to be applied to each electrode unit 33 of the electrode sheet 13 in a manner of maintaining the voltage or current amplitude of the alternating electric signal applied to each electrode unit 33 of the electrode sheet 13 unchanged. When the temperature corresponding to the temperature detection signal is close to the preset temperature threshold, the alternating electric signal is continued to be applied to each electrode unit 33 of the electrode sheet 13 in a manner of maintaining the voltage or current amplitude of the alternating electric signal applied to each electrode unit 33 of the electrode sheet 13 unchanged, or the alternating electric signal is continued to be applied to each electrode unit 33 of the electrode sheet 13 in a manner of reducing the voltage or current amplitude of the alternating electric signal applied to each electrode unit 33 of the electrode sheet 13.

[0176] In some other embodiments, controlling the intensity of the alternating electrical signal according to the comparison result in step 242 specifically includes:

[0177] Step 2425: When the temperature at at least one electrode unit 33 exceeds a preset temperature threshold, determine the number of over-temperature row groups.

[0178] Step 2426 : When the number of over-temperature row groups exceeds a preset number threshold, stop applying the alternating electrical signal to all electrode units 33 of the electrode sheet 13 .

[0179] Step 2427: When the number of over-temperature row groups does not exceed the preset number threshold, stop applying the alternating electrical signal to all electrode units 33 in the row group of the electrode unit 33 in the electrode sheet 13 where the electrode unit 33 exceeding the preset temperature threshold is located.

[0180] Furthermore, while stopping the application of the alternating electrical signal to all electrode cells 33 in the row group containing the electrode cell 33 that exceeds the preset temperature threshold in the electrode sheet 13, the alternating electrical signal continues to be applied to the electrode cells 33 in other row groups in the electrode sheet 13. The intensity of the alternating electrical signal applied to the electrode cells 33 in other row groups in the electrode sheet 13 is adjustable.

[0181] Step 2428: When the number of over-temperature row groups does not exceed the preset number threshold, if the temperature at each electrode unit 33 in the non-over-temperature row group does not exceed the first preset temperature, increase the intensity of the alternating electric signal applied to the electrode unit 33 of the non-over-temperature row group, wherein the first preset temperature is less than the preset temperature threshold.

[0182] In step 2428, the electric field strengths corresponding to the row groups whose alternating electric signal strengths are increased have the same increase magnitude.

[0183] Step 2429: When the number of over-temperature row groups does not exceed the preset number threshold, if the temperature of at least one electrode unit 33 in the non-over-temperature row group exceeds the first preset temperature and is less than the preset temperature threshold, the alternating electric signal strength currently applied to the electrode unit 33 of the non-over-temperature row group is maintained unchanged.

[0184] Step 2430: When the number of over-temperature row groups does not exceed the preset number threshold, if the temperature of at least one electrode unit 33 in the non-over-temperature row group exceeds the second preset temperature and is less than the preset temperature threshold, the intensity of the alternating electric signal applied to the electrode unit 33 of the non-over-temperature row group is reduced, wherein the second preset temperature is greater than the first preset temperature and less than the preset temperature threshold.

[0185] In step 2430, the electric field strength corresponding to each row group whose alternating electric signal strength is reduced has the same reduction amplitude.

[0186] Exemplarily, when the temperature corresponding to the temperature detection signal is far below the preset temperature threshold, the alternating electric signal is continued to be applied to each electrode unit 33 of the electrode sheet 13 in a manner of increasing the voltage or current amplitude of the alternating electric signal applied to each electrode unit 33 of the electrode sheet 13, or the alternating electric signal is continued to be applied to each electrode unit 33 of the electrode sheet 13 in a manner of maintaining the voltage or current amplitude of the alternating electric signal applied to each electrode unit 33 of the electrode sheet 13 unchanged. When the temperature corresponding to the temperature detection signal is close to the preset temperature threshold, the alternating electric signal is continued to be applied to each electrode unit 33 of the electrode sheet 13 in a manner of maintaining the voltage or current amplitude of the alternating electric signal applied to each electrode unit 33 of the electrode sheet 13 unchanged, or the alternating electric signal is continued to be applied to each electrode unit 33 of the electrode sheet 13 in a manner of reducing the voltage or current amplitude of the alternating electric signal applied to each electrode unit 33 of the electrode sheet 13.

[0187] Reference Figure 11 As shown, the present application also provides a method for identifying the type of electrode sheet, which includes the following steps:

[0188] Step 210: Control the multiplexing switching unit so that the dual-purpose signal line 19 corresponding to any row group in the corresponding electrode sheet 13 is connected to the corresponding temperature sampling point, wherein the first switching end 1 of the rectifier switching unit 16 corresponding to the row group in the corresponding electrode sheet 13 is connected to the fixed end 3.

[0189] Step 220 : Control the control switches 54 corresponding to each column group to sample the analog temperature signals of the corresponding electrode units 33 based on the corresponding temperature sampling points to determine the temperature detection signals of the respective electrode units 33 in each electrode sheet 13 .

[0190] Step 250: Identify the type of the electrode sheet 13 according to the temperature detection signal.

[0191] Specifically, when the electrode sheet 13 is qualified or there is no abnormality or failure in each temperature detection unit 35 of the electrode sheet 13, the type of the electrode sheet 13 is identified based on the temperature detection signal detected by the temperature detection unit 35 of each electrode unit 33 in the electrode sheet 13.

[0192] The present application also provides a signal control method for tumor electric field therapy, which is used for the above-mentioned tumor electric field therapy system 100 or for the above-mentioned electrode sheet 13. The method includes: combining and controlling the control switch 54 and the bidirectional switching switch 55 electrically connected to the electrode sheet 13 so that each electrode unit 33 of the electrode sheet 13 switches between applying an alternating electric signal and collecting a temperature detection signal.

[0193] Reference Figure 12As shown, the present application also provides a signal control method for tumor electric field therapy, which is used for the above-mentioned electrode sheet 13, and the method includes:

[0194] Step 310: Combining and controlling the control switch 54 and the bidirectional switch 55 electrically connected to the corresponding electrode sheet 13 to apply an alternating electrical signal to each electrode unit 33 of the electrode sheet 13 and executing step 320;

[0195] Step 320: Combining and controlling the control switch 54 and the bidirectional switch 55 electrically connected to the electrode sheet 13 to collect temperature detection signals of the electrode units 33 of the electrode sheet 13 in rows or columns and executing step 330;

[0196] Step 330: Determine the combined control mode of the control switch 54 and the bidirectional switch 55 electrically connected to the electrode sheet 13 according to the collected temperature detection signal and execute step 340;

[0197] Step 340 : Control the working state of each electrode unit 33 of the electrode sheet 13 according to the determined combined control mode of the control switch 54 and the bidirectional switch 55 .

[0198] The operating state of each electrode unit 33 of the electrode sheet 13 in step 340 includes at least one of: stopping applying the alternating electrical signal and continuing to collect the temperature detection signal; and stopping collecting the temperature detection signal and continuing to apply the alternating electrical signal. Continuing to apply the alternating electrical signal includes continuing to apply the alternating electrical signal by increasing the voltage or current amplitude of the currently applied alternating electrical signal, continuing to apply the alternating electrical signal by maintaining the voltage or current amplitude of the currently applied alternating electrical signal unchanged, or continuing to apply the alternating electrical signal by reducing the voltage or current amplitude of the currently applied alternating electrical signal.

[0199] The operating state of each electrode unit 33 of the electrode sheet 13 is determined by the temperature detection signal it collects. Each electrode unit 33 of the electrode sheet 13 is divided into different regions. Each electrode unit 33 in each region is controlled by a combination of a control switch 54 and a bidirectional switch 55 to cyclically switch between applying an alternating electrical signal and collecting a temperature detection signal.

[0200] This embodiment of the present application provides another electrode temperature detection method for the tumor electric field therapy system 100, please refer to Figure 13 As shown, the temperature detection method includes:

[0201] Step 510: disconnect the input of the alternating electrical signal of the electrode sheet 13, perform combination control on the multiple control switches 54 and the multiple bidirectional switches 55, and obtain the temperature detection signal of the temperature sensor 34 of the electrode sheet 13 corresponding to each combination in all combinations;

[0202] Step 520: sampling and converting the temperature detection signal detected by each temperature sensor 34 in the electrode sheet 13 to obtain a digital temperature signal;

[0203] 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 33 according to the digital temperature signal.

[0204] In step 510, the combined control of the plurality of control switches 54 and the plurality of bidirectional switches 55 specifically includes:

[0205] Step 511: Control the plurality of bidirectional switches 55 so that the dual-purpose signal lines 19 corresponding to each row group in the corresponding electrode sheet 13 are sequentially connected to the corresponding temperature sampling points; one bidirectional switch 55 is placed at end 1, and the remaining bidirectional switches 55 are placed at end 2, so as to electrically connect the signal terminals 35-2 of each temperature detection unit 35 corresponding to each electrode unit 33 in the row group corresponding to the bidirectional switch 55 placed at end 1 with the corresponding ADC unit 52;

[0206] Step 512: Sequentially and individually closing one of the plurality of control switches 54 in a time-sharing manner to collect the temperature detection signals detected by the temperature detection units 35 corresponding to the electrode units 33 in the corresponding row group one by one.

[0207] In step 512 , one of the plurality of control switches 54 is closed in sequence and in a time-sharing manner, so that the ADC unit 52 and each temperature detection unit 35 in the column group corresponding to the closed control switch 54 are grounded in sequence.

[0208] In this way, the temperature detection signals of the corresponding temperature detection units 35 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 33 on the electrode sheet 13 can be obtained, thereby making the temperature detection of the patient's body surface more comprehensive and accurate.

[0209] For the tumor electric field therapy system 100 of the embodiment of the present application, the temperature of a single electrode unit 33 can be detected. For example, the temperature of a single electrode unit 33 located in the first column group can be detected. Taking electrode unit 33-1 as an example: disconnect the input of the alternating electric signal, set the bidirectional switch 55 corresponding to the row group where the electrode unit 33-1 that needs to be individually measured to end 1, and set the remaining bidirectional switches 55 to end 2; at the same time, turn on and ground the control switch 54 corresponding to the column group where the electrode unit 33-1 that needs to be individually measured to end, and turn off all the remaining control switches 54. In this way, the temperature detection signal of the temperature detection unit 35 corresponding to the electrode unit 33-1 that needs to be individually measured can be sampled to obtain the temperature of the electrode unit 33-1. For example, the first bidirectional switch 55-1 corresponding to electrode unit 33-1 is set to terminal 1, and the remaining bidirectional switches (55-2 through 55-4) are all set to terminal 2. At the same time, the first control switch 54-1 corresponding to electrode unit 33-1 is closed and grounded, and the remaining control switches (54-2 through 54-5) are all opened. This allows the temperature of electrode unit 33-1 to be detected. Similarly, the temperatures of the other electrode units 33-6, 33-11, and 33-16 in the first column group can also be individually detected. In addition to temperature detection for a single electrode unit 33 in the first column group, the temperature detection signals for the other electrode units 33 are combined signals. For example, when the first bidirectional switch 55-1 corresponding to electrode unit 33-2 is set to terminal 1, and the remaining bidirectional switches (55-2 to 55-4) are all set to terminal 2; at the same time, the second control switch 54-2 corresponding to electrode unit 33-2 is closed and grounded, and the remaining control switches (54-1, 54-3 to 54-5) are all opened, the temperature detection signal obtained at this time is the combined temperature detection signal of electrode unit 33-1 and electrode unit 33-2. The temperature detection signal of electrode unit 33-2 is obtained by subtracting the temperature detection signal of electrode unit 33-1 from the combined temperature detection signal.

[0210] The present application also provides another method for applying an alternating electric signal for tumor electric field therapy, which is applied to the above-mentioned tumor electric field therapy system 100. Please refer to Figure 14 As shown, the alternating electric signal applying method includes:

[0211] Step 610: Determine the region (1-4) where the electrode unit 33 to which the alternating electrical signal is to be applied is located in the electrode sheet 13;

[0212] Step 611: Combining and controlling a plurality of control switches 54 and a plurality of bidirectional switches 55 electrically connected to the electrode sheet 13 to apply an alternating electrical signal.

[0213] In step 611, the combination of controlling the plurality of control switches 54 and the plurality of bidirectional switches 55 electrically connected to the electrode sheet 13 is specifically as follows:

[0214] Step 612: Disconnect all control switches 54 electrically connected to the electrode sheet 13;

[0215] Step 613: determining the row groups where the electrode units 33 in the areas where the alternating electric signals need to be applied are located according to the areas where the electrode units 33 in the areas where the alternating electric signals need to be applied are located;

[0216] Step 614: determining the bidirectional switches 55 electrically connected to the electrode units 33 in the row groups according to the row groups where the electrode units 33 to which the alternating electrical signals are applied are located;

[0217] Step 615: Control the bidirectional switching switch 55 electrically connected to the electrode unit 33 to which the alternating electric signal needs to be applied so that the electrode unit 33 to which the alternating electric signal needs to be applied is electrically connected to the alternating power line 57 to apply the alternating electric signal; at the same time, control the remaining bidirectional switching switches 55 so that the electrical connection between each electrode unit 33 in the area where the alternating electric signal does not need to be applied and the alternating power line 57 is disconnected to stop applying the alternating electric signal.

[0218] In step 615, "electrically connecting the electrode units to which alternating electric signals need to be applied to the alternating power line 57 to apply the alternating electric signals and disconnecting the electrical connection between the electrode units 33 in the area where the alternating electric signals do not need to be applied and the alternating power line 57 to stop applying the alternating electric signals" is achieved by placing the bidirectional switching switches 55 electrically connected to the electrode units 33 in the row groups corresponding to the areas (1-4) in the electrode sheet 13 to which the alternating electric signals are to be applied at their 2 ends, and placing all the bidirectional switching switches 55 electrically connected to the electrode units 33 in the remaining row groups at their 1 end.

[0219] The first controller 51 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.

[0220] The present application also provides a method for applying an alternating electric signal based on a temperature detection signal, which is used in the above-mentioned tumor electric field treatment system 100. Figure 15 As shown, the application method includes:

Different alternating electric signals, such as different voltages or currents, cannot be applied simultaneously to electrode units 33 in different rows. Figures 27 to 31 Another tumor therapy field treatment system 100' is described below. Its main concept is the same as that of the aforementioned tumor therapy field treatment system 100, with the following difference: in this tumor therapy field treatment system 100', each row of electrode units 33' on the corresponding electrode sheet 13' in the adapter 20' and the electric field generator 30' is provided with a corresponding alternating power line 57', so that different alternating electrical signals, such as voltages or currents of different magnitudes, can be applied simultaneously to different rows of electrode units 33'.

[0408] The specific structure of the adapter 20' is similar to the above adapter 20, except that: Figure 28 and Figure 30 , the adapter 20' is provided with four alternating current power lines 57' corresponding to each electrode sheet 13'. The four alternating current power lines 57' are provided in a one-to-one correspondence with the four row-group electrode units 33' of each electrode sheet 13'. Each electrode sheet 13' is provided with a corresponding bidirectional switch 55' and a grounding switch 54'. Both ends of the bidirectional switch 55' are electrically connected to a separate alternating current power line 57', so that the tumor electric field treatment system 100' can simultaneously apply different alternating current signals, such as different voltages or currents, to different row-group electrode units 33' in each electrode sheet 13' as needed.

[0409] The specific structure of the electric field generator 30' is similar to the above electric field generator 30, except that: Figure 28 and Figure 31A power switch 40' is provided for each alternating power line 57' connected between the AC signal generator 39' and the adapter 20' to individually control the on and off of the alternating electrical signal of each row group of electrode units 33' of each electrode sheet 13'.

The circuit lines (unnumbered) of the multi-way grounding lines 18' that are electrically connected to the electrode sheet 13' are grounded at one end close to the control switch 54'. The number of control switches 54' in each group of control switches 54' is related to the number of grounding lines 18' of the substrate 31' of the corresponding electrode sheet 13', and the two are equal in this embodiment. As Figure 28As shown, in this embodiment, the multiple control switches 54' in each group of control switches 54' are respectively a first control switch 54-1', a second control switch 54-2', a third control switch 54-3', a fourth control switch 54-4', and a fifth control switch 54-5'. The multiple control switches 54' in the same group each control the closing or opening of the corresponding ground line 18' of the same electrode sheet 13'.

The control switch 54' can be a mechanical switch, such as a relay. The control switch 54' can also be an electronic switch. Each control switch 54' can be opened and closed by an additional first controller 51'.

[0412] In this embodiment, the multiple groups of control switches 54' are all electronic switches. The first controller 51' is in communication connection with the multiple groups of control switches 54', and is used to cyclically control the opening and closing states of the multiple control switches 54' in each group of control switches 54', and then turn on each grounding wire 18' of the multiple grounding wires 18' of the corresponding electrode sheet 13' in turn and cooperate with the switching of the corresponding two-way switching switch 55' to collect the temperature of the patient's body surface detected by all temperature detection units 35' on the electrode sheet 13'. The number of each group of control switches 54' is not less than the number of grounding wires 18' of the substrate 31' of the corresponding electrode sheet 13'. In this embodiment, the number of each group of control switches 54' is the same as the number of grounding wires 18' of the corresponding electrode sheet 13'.

[0413] Each set of bidirectional switches 55' includes multiple bidirectional switches 55'. The multiple bidirectional switches 55' in each set are connected to the adapter 20' and are electrically connected to circuit lines (not numbered) that correspond one-to-one with the multiplexed signal lines 19' of a corresponding electrode sheet 13'. The number of bidirectional switches 55' in each set of bidirectional switches 55' is related to the number of dual-purpose signal lines 19' of the substrate 31' of the corresponding electrode sheet 13', and is greater than or equal to the number of dual-purpose signal lines 19' of the substrate 31' of the corresponding electrode sheet 13'. In this embodiment, the number of bidirectional switches 55' is equal to the number of dual-purpose signal lines 19' of the substrate 31' of the corresponding electrode sheet 13'. Each bidirectional switch 55' has two ends marked 1 and 2. One end of multiple bidirectional switches 55' in the same group is electrically connected to corresponding detection channels of multiple detection channels of a corresponding group of ADC units 52' through temperature sampling points (unnumbered).

The multiple bidirectional switches 55' in the same group each control a corresponding dual-purpose signal line 19' in the multiplexed dual-purpose signal line 19' of the same electrode sheet 13' to switch between transmitting an alternating electrical signal and transmitting a temperature detection signal. Specifically, the first bidirectional switch 55-1' is used to control the switching of the first dual-purpose signal line 19-1' of the corresponding electrode sheet 13' between transmitting the alternating electric signal output by the alternating power line 57-1' and transmitting the temperature detection signal, thereby controlling the parallel conduction of each electrode unit 33' from the electrode unit 33-1' to the electrode unit 33-5' in the first row group of the electrode sheet 13' and the conduction of the signal end 35-2' of each temperature detection unit 35' corresponding to the electrode unit 33-1' to the electrode unit 33-5' in the first row group. The switching of the first control switch 54-1', the second control switch 54-2', the third control switch 54-3', the fourth control switch 54-4', and the fifth control switch 54-5' is coordinated with the corresponding first control switch 54-1', the second control switch 54-2', the third control switch 54-3', the fourth control switch 54-4', and the fifth control switch 54-5', so that the first row electrode unit 33-1' to the electrode unit 33-5' transmit a separate alternating electrical signal to the patient or the temperature detection signal (such as an analog temperature signal) detected by the corresponding one or more combinations of the temperature detection units 35' corresponding to the electrode units 33' is sampled and output to the corresponding ADC unit 52'. The second bidirectional switch 55-2' is used to control the switching of the second dual-purpose signal line 19-2' of the corresponding electrode sheet 13' between transmitting the alternating electric signal output by the alternating power line 57-2' and transmitting the temperature detection signal, thereby controlling the parallel conduction of each electrode unit 33' from the electrode unit 33-6' to the electrode unit 33-10' in the second row group of the electrode sheet 13' and the conduction of the signal end 35-2' of each temperature detection unit 35' corresponding to the electrode unit 33-6' to the electrode unit 33-10' in the second row group. and cooperate with the corresponding first control switch 54-1', second control switch 54-2', third control switch 54-3', fourth control switch 54-4', and fifth control switch 54-5', so that the second row electrode units 33-6' to electrode units 33-10' transmit separate alternating electrical signals to the patient or enable the temperature detection signals (such as analog temperature signals) detected by the corresponding one or more combinations of the temperature detection units 35' corresponding to these electrode units 33' to be sampled and output to the corresponding ADC unit 52';The third bidirectional switch 55-3' is used to control the switching between the third dual-purpose signal line 19-3' of the corresponding electrode sheet 13' in transmitting the alternating electric signal output by the alternating power line 57-3' and the temperature detection signal, thereby controlling the parallel conduction of each electrode unit 33' from the electrode unit 33-11' to the electrode unit 33-15' in the third row group of the electrode sheet 13' and the conduction of the signal end 35-2' of each temperature detection unit 35' corresponding to the electrode unit 33-11' to the electrode unit 33-15' in the third row group. and cooperate with the corresponding first control switch 54-1', second control switch 54-2', third control switch 54-3', fourth control switch 54-4', and fifth control switch 54-5', so that the third row electrode units 33-11' to electrode units 33-15' transmit separate alternating electrical signals to the patient or enable the temperature detection signals (such as analog temperature signals) detected by the corresponding one or more combinations of the temperature detection units 35' corresponding to these electrode units 33' to be sampled and output to the corresponding ADC unit 52'; The fourth bidirectional switch 55-4' is used to control the switching between the fourth dual-purpose signal line 19-4' of the corresponding electrode sheet 13' in transmitting the alternating electric signal output by the alternating power line 57-4' and the temperature detection signal, thereby controlling the parallel conduction of each electrode unit 33' from the electrode unit 33-16' to the electrode unit 33-20' in the fourth row group of the electrode sheet 13' and the conduction of the signal end 35-2' of each temperature detection unit 35' corresponding to the electrode unit 33-16' to the electrode unit 33-20' in the fourth row group. The bidirectional switch 55' is switched and cooperates with the corresponding first control switch 54-1', second control switch 54-2', third control switch 54-3', fourth control switch 54-4', and fifth control switch 54-5' to enable the fourth row of electrode units 33-16' to electrode units 33-20' to transmit separate alternating electrical signals to the patient or enable the temperature detection signals (such as analog temperature signals) detected by the corresponding one or more combinations of the temperature detection units 35' corresponding to these electrode units 33' to be sampled and output to the corresponding ADC unit 52'. The above-mentioned bidirectional switch 55' can be a mechanical switch, such as a relay.

Each group of ADC units 52' includes a plurality of detection channels A, B, C, and D, and each detection channel A, B, C, and D is used to connect to a corresponding one of the multiplexed signal lines 19' through the corresponding bidirectional switching switch 55'. Figure 28 As shown, each ADC unit 52' includes a total of four detection channels A, B, C, and D, namely the first detection channel A, the second detection channel B, the third detection channel C, and the fourth detection channel D. The first detection channel A is connected to the first dual-purpose signal line 19-1' via one end of the first bidirectional switch 55-1', the second detection channel B is connected to the second dual-purpose signal line 19-2' via one end of the second bidirectional switch 55-2', the third detection channel C is connected to the third dual-purpose signal line 19-3' via one end of the third bidirectional switch 55-3', and the fourth detection channel D is connected to the fourth dual-purpose signal line 19-4' via one end of the fourth bidirectional switch 55-4'. Each detection channel A, B, C, and D is used to receive the temperature detection signal collected by the temperature detection unit 35' corresponding to the electrode unit 33' to which the corresponding dual-purpose signal line 19' is connected. In addition, each detection channel A, B, C, D is connected to a first power module 58' for providing detection voltage to the detection channel A, B, C, D via a corresponding voltage divider resistor 53' in the adapter 20'. The first power module 58' provides DC power.

[0417] In this embodiment, the first communication unit 56' is configured to acquire digital temperature signals output by multiple sets of ADC units 52' and transmit the digital temperature signals to the electric field generator 30'. The electric field generator 30' is further configured to control and adjust the voltage of the alternating electrical signal provided to the multiple electrode units 33' of the electrode sheet 13' based on the received digital temperature signals. For example, when any of the multiple digital temperature signals received exceeds a preset threshold, it indicates that the temperature detected by the temperature detection unit 35' corresponding to at least one electrode unit 33' in the electrode sheet 13' exceeds a preset threshold temperature (e.g., 41°C, 42°C, etc.). At this time, the voltage of the alternating electrical signal output by the electric field generator 30' can be appropriately reduced or stopped to prevent the electrode units 33' of the electrode sheet 13' from overheating when the alternating electrical signal is applied, thereby preventing low-temperature burns on the patient's skin. The above-mentioned preset threshold temperature and preset threshold value can be determined based on human safety thresholds. The first communication unit 56' is controlled by the first controller 51' and serially transmits the digital temperature signals converted by the multiple sets of ADC units 52'. In this embodiment, the preset threshold temperature may be a value within the range of 36°C-45°C.
