Description

Technical Field

[0001] This application relates to tumor electric field therapy technology, and particularly to a tumor electric field therapy system, an electrode patch, a tumor treatment device and a method. Background Art

[0002] Tumor electric field therapy is a treatment method that uses low-intensity, medium-high frequency alternating electric fields to prevent the formation of spindle microtubules during the mitosis of certain tumor cells, inhibit the separation of intracellular organelles during the cell division phase, and induce apoptosis of cells in the mitosis phase, 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 vulnerable to tumor electric field therapy. Tumor electric field therapy disrupts the normal aggregation of tubulin by applying a directional force on polar particles (such as macromolecules and organelles) within cells. These processes may lead to physical damage to the cell membrane and apoptosis. At the end of cell mitosis, the structural morphology of the cleavage furrow causes uneven 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 charged substances in the cell move towards the cleavage furrow, disturbing or even destroying the formation of the cell structure, and ultimately leading to the failure of cell division and apoptosis.

[0004] In the tumor electric field therapy system in the related art, an electric field application device is used to transmit an alternating electric signal for tumor electric field therapy to the electrode patch, and then an alternating electric field is applied to the tumor site of the patient through the electrode patch for tumor electric field therapy. When the tumor treatment electric field is applied to the patient's body, heat will accumulate at the application site, and the temperature will also increase accordingly. Therefore, it is necessary to monitor the temperature at the application site. When the temperature is too high, it is necessary to adjust the electric field intensity in a timely manner to reduce the risk of scalding the patient's skin caused by excessive temperature.

[0005] The tumor electric field therapy system includes at least a pair of electrode patches, and there are multiple electrode units in each electrode patch. Even if the same alternating electric signal is applied to each electrode unit, the heat generated on each electrode unit will vary depending on its location, that is, the temperature of each electrode unit on the entire electrode patch will not be exactly the same. In this way, it is possible that the temperature of some electrode units in the entire electrode patch 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 separate control for the over-temperature electrode units. However, for the electrode patches in the related art, implementing separate control for the electrode units requires setting a conductive trace for each electrode unit in the substrate of the electrode patch, which will increase the number of conductive traces in the electrode patch substrate, making it difficult to bend the electrode patch, and the cable electrically connected to the electrode patch will also thicken, increasing the overall weight of the electrode patch and being unfavorable for the application of the electrode patch.

[0111] The embodiments of the technical solution of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present application more clearly, so they are only examples and cannot be used to limit the protection scope of the present application.

[0112] Embodiment 1:

[0113] Figure 1 The figure shows a schematic diagram of a tumor electric field therapy system 100 according to an embodiment of the present application. As Figure 1 shown, the tumor electric field therapy system 100 includes: at least a pair of electrode patches 13, a adapter 20 connected to the at least a pair of electrode patches 13, and an electric field generator 30 connected to the adapter 20. The at least a pair of electrode patches 13 can be arranged in pairs on the body surface of a patient, such as Figure 1 the 4 electrode patches 13 in the figure, and every two electrode patches 13 are arranged as a pair on the body surface of the patient. The electric field generator 30 is used to supply power to the at least a pair of electrode patches 13, so that the at least a pair of electrode patches 13 generate an alternating electric field for treating tumors. The adapter 20 is electrically connected between the at least a pair of electrode patches 13 and the electric field generator 30, and is used to transmit the alternating electric signal generated by the electric field generator 30 to the at least a pair of electrode patches 13. That is to say, the electric field generator 30 can generate an alternating electric signal, and the generated alternating electric signal is transmitted to each electrode patch 13 through the adapter 20, so as to generate an alternating electric field for treating tumors between the same pair of electrode patches 13, and apply an alternating electric field to the tumor site of the patient for tumor treatment.

[0114] As Figure 1 shown, in this embodiment, the number of electrode patches 13 is 4, and each electrode patch 13 includes a plurality of electrode units 33 with the same number. Each electrode unit 33 is electrically connected to the adapter 20, and the number of electrode units 33 on each electrode patch 13 is 20. In other embodiments, the tumor electric field therapy system 100 may also have more or fewer electrode patches 13; in other embodiments, each pair of electrode patches 13 has the same number of electrode units 33, and different pairs of electrode patches 13 may have different numbers of electrode units 33; in other embodiments, the number of electrode units 33 on each electrode patch 13 may be 9, 13, etc.

[0115] Figure 3 and Figure 4 are Figure 1 schematic diagrams of the circuit connection between the electrode patch 13 and the adapter 20 in two working states of the tumor electric field therapy system 100 shown in the figure. It should be noted that: Figure 3 and Figure 4 the arrangement of the electrode units 33 shown is to more clearly show the electrical connection situation between an electrode patch 13 and the adapter 20, Figure 3 and Figure 4The arrangement of the electrode units 33 shown does not represent the arrangement of the electrode units 33 in the spatial structure. Combining Figure 1 , Figure 3 and Figure 4 , the electrode sheet 13 includes: a substrate 31, a plurality of electrode units 33 spaced and electrically connected to the substrate 31, a plurality of temperature detection units 35, and a first cable 15 electrically connected to the substrate 31. The substrate 31 can be a flexible printed circuit board. A plurality of conductive traces are embedded in the substrate 31, and the plurality of conductive traces include a plurality of ground wires 18 and a plurality of dual-purpose signal lines 19. The first cable 15 has five core wires (not shown), and each core wire is respectively and electrically connected to the plurality of ground wires 18 and the plurality of dual-purpose signal lines 19 of the substrate 31 in a one-to-one correspondence. In this embodiment, the total number of the ground wires 18 and the dual-purpose signal lines 19 embedded in the substrate 31 does not exceed 10, so the number of wires of the first cable 15 does not exceed 10.

[0116] The plurality of electrode units 33 are configured into a plurality of row groups and a plurality of column groups. In this embodiment, 20 electrode units 33 are provided on each electrode sheet 13, and the 20 electrode units 33 are sorted and grouped in the order of 1 to 20 in terms of circuit connection, and are divided into four row groups and five column groups, that is, the 20 electrode units 33 are arranged in four rows and five columns in terms of 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 units 33 and the temperature detection units 35 are both welded to the substrate 31, and the electrode unit 33 is short-circuited with the signal terminal 35-2 of the corresponding temperature detection unit 35. Since the plurality of temperature detection units 35 are provided in 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 terms of circuit connection. It should be noted that the arrangement method here is to more clearly show the electrical connection situation between the electrode sheet 13 and the adapter 20, and does not represent the arrangement of the electrode units 33 in the spatial structure, and its spatial structure may be as Figure 2The shown substantially array-like structure can also be other structures, such as petal-shaped or scattered, etc., and can be regular or irregular structures. The electrode unit 33 is configured to apply an alternating electric field to the tumor site of the patient. The temperature detection unit 35 is configured to detect the temperature of the patient's body surface in contact with the electrode patch 13, that is, the temperature at the corresponding electrode unit 33, and output a temperature detection signal to the adapter 20. In this embodiment, the multi-purpose signal lines 19 of the substrate 31 are respectively arranged in one-to-one correspondence with multiple column groups of the electrode unit 33, and are configured to transmit the alternating electric signals generated by the electric field generator 30 to each electrode unit 33 in the corresponding column group. That is, the electrode units 33 in the same column group are all short-circuited through the same multi-purpose signal line 19 of the substrate 31, and the electrode units 33 in different column groups are respectively connected in parallel through different multi-purpose signal lines 19 of the substrate 31. The multi-purpose signal line 19 of the substrate 31 is electrically connected to the first cable 15, and then electrically connected to the electric field generator 30 through the adapter 20. Further, the multi-purpose signal line 19 of the substrate 31 receives the alternating electric signals generated by the electric field generator 30 through the first cable 15 and the adapter 20.

[0117] The multiple ground wires 18 are respectively arranged in one-to-one correspondence with multiple row groups of the electrode unit 33, and the multiple ground wires 18 are respectively used to short-circuit and ground the corresponding temperature detection units 35 in each row group in sequence. That is, the respective ground terminals 35-1 of the multiple temperature detection units 35 in the same row group are all short-circuited through the same ground wire 18 of the substrate 31, and the ground terminals 35-1 of the temperature detection units 35 in different row groups are respectively connected in parallel through different ground wires 18 of the substrate 31. During the time period of temperature detection, only one of the multiple ground wires 18 is conducting at the same moment, and the other three are all disconnected.

[0118] Each path in the multi-purpose signal line 19 is also configured to short-circuit the signal terminal 35-2 of at most one temperature detection unit 35 in each row group to an external device for receiving detection signals, where the signal terminals 35-2 of the temperature detection units 35 connected by each path in the multi-purpose signal line 19 are different from each other, so as to avoid the multi-purpose signal line 19 outputting duplicate signals subsequently. That is, when the number of electrode units 33 in a row group is the same as the number of paths of the multi-purpose signal line 19, each path of the multi-purpose signal line 19 is electrically connected to the signal terminal 35-2 of a different temperature detection unit 35 in that row group respectively; when the number of electrode units 33 in a row group is less than the number of paths of the multi-purpose signal line 19, there is at least one path of the multi-purpose signal line 19 not electrically connected to the signal terminal 35-2 of the temperature detection unit 35, and each of the remaining paths of the multi-purpose signal line 19 is electrically connected to the signal terminal 35-2 of a different temperature detection unit 35 in that row group respectively. In this embodiment, the external device for receiving detection signals is an adapter 20. The signal terminals 35-2 of multiple temperature detection units 35 located in different column groups are respectively connected in parallel through different paths of the multi-purpose signal line 19 of the substrate 31, and the signal terminals 35-2 of multiple temperature detection units 35 located in the same column group are all short-circuited to the same path of the multi-purpose signal line 19 of the substrate 31.

[0119] In this embodiment, when a temperature detection unit 35 is configured for temperature detection at each electrode unit 33, the above circuit design is adopted to reduce the number of wires of the first cable 15, avoid the cable becoming thicker and the softness of the cable becoming harder, which increases the difficulty of cable fixation; at the same time, avoid the increase in the number of wires of the first cable 15 affecting the adhesion effect between the electrode patch 13 and the corresponding body surface of the patient's tumor site. The ground wire 18 and the multi-purpose signal line 19 embedded in the substrate 31 are a total of 9 circuit paths. Specifically, in this embodiment, the ground wire 18 embedded in the substrate 31 is 4 circuit paths, and the multi-purpose signal line 19 is 5 circuit paths. The number of the ground wire 18 is related to the number of row groups M of the electrode units 33, which is greater than or equal to the number of row groups of the electrode units 33, and M is a positive integer. The number of the multi-purpose signal line 19 is related to the number of column groups N of the electrode units 33, which is greater than or equal to the number of column groups of the electrode units 33, and N is a positive integer. The circuit L embedded in the substrate 31 of the electrode patch 13 is equal to the sum of the number of the ground wire 18 and the number of the multi-purpose signal line 19. In this embodiment, the number of the ground wire 18 is equal to the number of row groups M of the electrode units 33; the multi-purpose signal line 19 is equal to the number of column groups N of the electrode units 33.

[0120] Multiple electrode units 33 are arranged at intervals on the substrate 31 in a substantially two-dimensional array form. As Figure 2As shown, the electrode sheet 13 in this embodiment includes 20 electrode units 33 and 20 temperature detection units 35 corresponding to the electrode units 33. The 20 electrode units 33 are arranged in a four-row and six-column array. The first row and the fourth row each have four electrode units 33, and the second row and the third row each have six electrode units 33. The four electrode units 33 in each of the first row and the fourth row are located in the columns from the second column to the fifth column, and the six electrode units 33 in each of the second row and the third row are located in the columns from the first column to the sixth column. The 4 electrode units 33 in the first row are divided into region 1, the electrode units 33 in the first column of the second row, the first column of the third row, the second column and the third column of the fourth row are divided into region 2, the electrode units 33 in the sixth column of the second row, the sixth column of the third row, the fourth column and the fifth column of the fourth row are divided into region 3, the electrode units 33 in the second column and the third column of the second row and the second column and the third column of the third row are divided into region 4, and the electrode units 33 in the fourth column and the fifth column of the second row and the fourth column and the fifth column of the third row are divided into region 5. Each region (1-5) corresponds to a column group respectively. In some other embodiments, the 20 electrode units 33 can also be arranged in other ways. Of course, in some other embodiments, the electrode sheet 13 can also have other numbers of electrode units 33. In short, the implementation of this application is not limited by the number and arrangement form of the electrode units 33 of the electrode sheet 13.

[0121] Each electrode unit 33 can apply an alternating electric signal, and thus the paired electrode plates 13 are used to apply an alternating electric field to the tumor site of the patient. Optionally, the electrode unit 33 is a dielectric element, such as a ceramic sheet, or can also be a polymer dielectric layer composed of a polymer material. Each temperature detection unit 35 is provided corresponding to an electrode unit 33 to detect the temperature at the corresponding electrode unit 33. Each temperature detection unit 35 can be disposed at any position of the corresponding electrode unit 33. In this embodiment, each electrode unit 33 is provided with a through hole 331, and the through hole 331 is adapted to mount the temperature detection unit 35. For example, the middle of each electrode unit 33 has a through hole 331 penetrating therethrough, and a corresponding temperature detection unit 35 is received in the through hole 331 of each electrode unit 33. Each temperature detection unit 35 includes a temperature sensor 34 and a diode 36. 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 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 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 sensors other than thermistors. Each temperature sensor 34 corresponds to a diode 36, and the diode 36 is connected in series with the temperature sensor 34 of the same electrode unit 33, which can prevent the reverse inflow of current to prevent the detection signal from other electrode units 33 from affecting the temperature sensor 34.

[0122] Such as Figure 3 Or Figure 4As shown, the electrode sheet 13 of this embodiment includes four ground wires 18, and each ground wire 18 is used to ground the ground terminals 35-1 of the temperature detection units 35 in the same row group. The four ground wires 18 of the electrode sheet 13 are respectively the first ground wire 18-1, the second ground wire 18-2, the third ground wire 18-3, and the fourth ground wire 18-4. Among the four row groups of the electrode sheet 13, the first row group is electrode units 33-1 to 33-5, the second row group is electrode units 33-6 to 33-10, the third row group is electrode units 33-11 to 33-15, and the fourth row group is electrode units 33-16 to 33-20. Specifically, the first ground wire 18-1 is used to ground electrode units 33-1 to 33-5 in the first row group; the second ground wire 18-2 is used to ground electrode units 33-6 to 33-10 in the second row group; the third ground wire 18-3 is used to ground electrode units 33-11 to 33-15 in the third row group; the fourth ground wire 18-4 is used to ground electrode units 33-16 to 33-20 in the fourth row group. It should be noted that these ground wires 18 can be selectively closed or opened, which can be achieved by connecting each ground wire 18 in series with a control switch 54 respectively, that is, the ground terminals 35-1 of the temperature detection units 35 corresponding to the electrode units 33 in each row group are commonly connected to the ground pin through a control switch 54, which will be described in detail below. The above "grounding the electrode unit 33" can refer to grounding the ground terminal 34-1 of the temperature sensor 34 corresponding to each electrode unit 33, or it can refer to the diode 36 being connected in series with the temperature sensor 34 corresponding to the same electrode unit 33 and being grounded together. In short, each ground wire 18 shorts and grounds the ground terminals 35-1 of the temperature detection units 35 corresponding to all the electrode units 33 in each row group.

[0123] As Figure 3 or Figure 4As shown, the electrode sheet 13 of this embodiment further includes five dual-purpose signal lines 19. One end of each dual-purpose signal line 19 is respectively connected to all the electrode units 33 in each column group, and the other end is connected to an adapter 20 for receiving temperature detection signals and transmitting alternating current signals. That is to say, for each row group, each dual-purpose signal line 19 can be selectively connected to one of the electrode units 33 or not connected to any of the electrode units 33 in this row group to avoid the subsequent output of duplicate signals by the dual-purpose signal lines 19. Specifically, the five 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, a fourth dual-purpose signal line 19-4, and a fifth dual-purpose signal line 19-5. One end of the first dual-purpose signal line 19-1 is respectively and simultaneously connected to four electrode units 33, namely the electrode unit 33-1, the electrode unit 33-6, the electrode unit 33-11, and the electrode unit 33-16, and the signal terminals 35-2 of the respective corresponding temperature detection units 35; one end of the second dual-purpose signal line 19-2 is respectively and simultaneously connected to four electrode units 33, namely the electrode unit 33-2, the electrode unit 33-7, the electrode unit 33-12, and the electrode unit 33-17, and the signal terminals 35-2 of the respective corresponding temperature detection units 35; one end of the third dual-purpose signal line 19-3 is respectively and simultaneously connected to four electrode units 33, namely the electrode unit 33-3, the electrode unit 33-8, the electrode unit 33-13, and the electrode unit 33-18, and the signal terminals 35-2 of the respective corresponding temperature detection units 35; one end of the fourth dual-purpose signal line 19-4 is respectively and simultaneously connected to four electrode units 33, namely the electrode unit 33-4, the electrode unit 33-9, the electrode unit 33-14, and the electrode unit 33-19, and the signal terminals 35-2 of the respective corresponding temperature detection units 35; one end of the fifth dual-purpose signal line 19-5 is respectively connected to four electrode units 33, namely the electrode unit 33-5, the electrode unit 33-10, the electrode unit 33-15, and the electrode unit 33-20, and the signal terminals 35-2 of the respective corresponding temperature detection units 35. In short, each dual-purpose signal line 19 short-circuits in parallel the electrode units 33 in the same column group and the signal terminals 35-2 of the respective corresponding temperature detection units 35 and is used to connect to an external device. It should be noted that these dual-purpose signal lines 19 can selectively transmit alternating current signals or receive temperature detection signals, which can be achieved by respectively connecting each dual-purpose signal line 19 in series with a bidirectional switch 55 and cooperating with the closing or opening of the ground wire 18.That is to say, after the signal terminals 35-2 of the temperature detection units 35 in each column group are respectively short-circuited with the corresponding electrode units 35, they are jointly connected to a switching unit (not labeled) through a dual-purpose signal line 19. The switching unit (not labeled) includes a plurality of bidirectional switching switches 55, which are configured to switch the dual-purpose signal line 19 to be connected to a temperature sampling point (not labeled) or an alternating power supply line 57. So that when the dual-purpose signal line 19 is connected to the temperature sampling point (not labeled), the temperature detection signals detected by the corresponding temperature detection units 35 in each row group are sampled based on the temperature sampling point (not labeled) by configuring the switch state of the control switch 54, and when the dual-purpose signal line 19 is connected to the alternating power supply line 57, the electrode units 33 of at least one column group are applied with an alternating electric signal based on the alternating power supply line 57, which will be described in detail below.

[0124] The multiple ground wires 18 and the multiple dual-purpose signal lines 19 are both conductive traces embedded in the substrate 31. The substrate 31 is electrically connected to the first cable 15. The multiple ground wires 18 and the multiple dual-purpose signal lines 19 embedded in the substrate 31 are respectively and electrically connected to the corresponding wires (not shown) in the first cable 15 one by one.

[0125] The tumor electric field treatment system 100 of this embodiment includes at least a pair of the above-mentioned electrode plates 13, an adapter 20 electrically connected to the electrode plates 13, and an electric field generator 30 electrically connected to the adapter 20. The adapter 20 is connected between the electrode plates 13 and the electric field generator 30. The electric field generator 30 provides an alternating electric signal to the multiple electrode units 33 of the electrode plates 13 or is used to receive the temperature detection signals output by the temperature detection units 35 corresponding to the multiple electrode units 33 through the adapter 20 and the dual-purpose signal line 19 of the electrode plates 13. The adapter 20 conveys the alternating electric signal generated by the electric field generator 30 to the dual-purpose signal line 19 of the electrode plates 13, and is also configured to receive the temperature detection signals output by the multiple dual-purpose signal lines 19 of the electrode plates 13.

[0126] Reference Figure 3 and Figure 4As shown, the adapter 20 includes: a first controller 51, multiple groups of ADC units 52 connected to the first controller 51, multiple groups of voltage dividing resistors 53 and multiple groups of control switches 54 corresponding to the multiple groups of ADC units 52 one by one, multiple groups of bidirectional switching switches 55 connected to the multiple groups of ADC units 52 one by one, a first communication unit 56, alternating current power lines 57 connected to each group of bidirectional switching switches 55 one by one, and a first power module 58 connected to the first communication unit 56, the first controller 51, and the multiple groups of ADC units 52 at the same time. The first power module 58 provides a DC power supply VCC for each electronic component of the adapter 20. The adapter 20 also includes multiple circuit lines (not labeled), and the multiple circuit lines (not labeled) are respectively electrically connected to multiple ground lines 18 and multiple dual-purpose signal lines 19 in the substrate 31 of the corresponding electrode plate 13 through the first cable 15 of the corresponding electrode plate 13. The multiple circuit lines (not labeled) include multiple alternating current power lines 57 that respectively transmit alternating current signals to the corresponding electrode plates 13 and are electrically connected to all the multiple dual-purpose signal lines 19 in the substrate 31 of the corresponding electrode plates 13, multiple circuit lines (not labeled) that are respectively electrically connected to the multiple dual-purpose signal lines 19 in the substrate 31 of the corresponding electrode plates 13 one by one and are used to supply power to each temperature detection unit 35 of the electrode plate 13 or transmit the temperature detection signal of the electrode plate 13, and multiple circuit lines (not labeled) that are respectively electrically connected to the multiple ground lines 18 in the substrate 31 of the corresponding electrode plates 13 one by one. The number L of circuit lines of the adapter 20 electrically connected to one electrode plate 13 is equal to the sum of the number of rows and columns of the electrode units 33 of the electrode plate 13; the number H of circuits of the adapter 20 electrically connected to X electrode plates 13 is X times the number of circuit lines of the adapter 20 electrically connected to a single electrode plate 13, that is, H = XL = X*(M + N). The number of groups of the control switches 54 and the number of groups of the bidirectional switching switches 55 are both related to the number of the electrode plates 13. The number of groups of the control switches 54 is the same as the number of groups of the bidirectional switching switches 55, and is not less than the number of the electrode plates 13. Optionally, the number of groups of the control switches 54 and the number of groups of the bidirectional switching switches 55 are both the same as the number of the electrode plates 13. The following takes the electrical connection between an electrode plate 13 with 20 electrode units 33 and the adapter 20 as an example for detailed description.

[0127] Each group of control switches 54 is provided with multiple control switches 54. The multiple control switches 54 are respectively connected into the adapter 20 and are respectively electrically connected to the circuit lines (not labeled) corresponding to the multiple ground lines 18 of a corresponding electrode plate 13 one by one, and are configured to control the conduction or disconnection of the multiple ground lines 18. The circuit lines (not labeled) respectively and electrically connected to the multiple ground lines 18 of the electrode plate 13 are grounded at one end close to the control switches 54. The number of control switches 54 in each group of control switches 54 is related to the number of ground lines 18 of the substrate 31 of the corresponding electrode plate 13, and the two are equal in this embodiment. As Figure 3 OrFigure 4 As shown, in this embodiment, the multiple control switches 54 are respectively 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. Multiple control switches 54 in the same group respectively control the closing or opening of the corresponding ground wires 18 of the same electrode plate 13 one by one. The first control switch 54-1 is used to control the closing or opening of the first ground wire 18-1 of the corresponding electrode plate 13, and then can cooperate with the corresponding group of bidirectional switching switches 55 to control the power-on and power-off of each temperature detection unit 35 corresponding to the five electrode units 33-1 to 33-5 in the first row group 33 of the electrode plate 13; the second control switch 54-2 is used to control the closing or opening of the second ground wire 18-2 of the electrode plate 13, and then can cooperate with the corresponding group of bidirectional switching switches 55 to control the power-on and power-off of the temperature detection units 35 corresponding to the five electrode units 33-6 to 33-10 in the second row group 33 of the electrode plate 13; the third control switch 54-3 is used to control the closing or opening of the third ground wire 18-3 of the electrode plate 13, and then can cooperate with the corresponding group of bidirectional switching switches 55 to control the power-on and power-off of each temperature detection unit 35 corresponding to the five electrode units 33-11 to 33-15 in the third row group 33 of the electrode plate 13; the fourth control switch 54-4 is used to control the closing or opening of the fourth ground wire 18-4 of the electrode plate 13, and then can cooperate with the corresponding group of bidirectional switching switches 55 to control the power-on and power-off of each temperature detection unit 35 corresponding to the five electrode units 33-16 to 33-20 in the fourth row group 33 of the electrode plate 13. The above control switches 54 can be mechanical switches, such as relays. The control switches 54 can also be electronic switches, and each control switch 54 can be opened and closed through an additional first controller 51.

[0128] In this embodiment, multiple groups of control switches 54 are all electronic switches.

When two ends of each set of two-way switching switches 55 are turned on and one end is turned off, an alternating electrical signal can be transmitted to each electrode unit 33 of the corresponding electrode sheet 13. When one end of each set of two-way switching switches 55 is turned on and two ends are turned off, 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 element 33 on the electrode sheet 13 in a time-sharing manner. The above-mentioned two-way switching switch 55 can be a mechanical switch, such as a relay. The two-way switching switch 55 can also be an electronic switch, and each two-way switching switch 55 can be switched by an additional first controller 51. ;

[0131] In this embodiment, the plurality of sets of two-way switches 55 are all electronic switches. The first controller 51 is in communication connection with the plurality of sets of two-way switches 55, and is used to control the plurality of two-way switches 55 in each set of two-way switches 55 to switch between their respective ends 1 and 2, and to coordinate the closing or opening of the corresponding control switch 54, so as to continuously monitor the temperature of the patient's body surface detected by all the temperature detection units 35 on the electrode sheet 13 or transmit an alternating electrical signal to the patient.

The electric field generator 30 is also configured to control and adjust the voltage of the alternating current signal provided to the multiple electrode units 33 of the electrode plate 13 according to the received digital signals. Exemplarily, when any one of the multiple received digital signals exceeds a preset threshold, it means that the temperature detected by the temperature detection unit 35 corresponding to at least one electrode unit 33 in the electrode plate 13 exceeds a preset temperature threshold (such as 41°C, 42°C, etc.). At this time, the voltage of the alternating current signal output by the electric field generator 30 can be appropriately reduced to avoid the temperature of the electrode unit 33 of the electrode plate 13 being too high when applying the alternating current signal and causing low-temperature burns to the patient's skin. The above preset temperature threshold and preset threshold can be determined according to the human safety threshold. The first communication unit 56 is controlled by the first controller 51 and serially transmits the digital signals converted by multiple groups of ADC units 52.

[0137] The working principle of the tumor electric field treatment system 100 of this embodiment will be described in detail below with reference to Figures 3 to 5 this.

[0138] Specifically, when it is necessary to detect the temperature at 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 each of the plurality of two-way switches 55 in a group of two-way switches 55 electrically connected to the electrode sheet 13 to turn on the 1-end and turn off the 2-end, so as to disconnect the alternating current signal applied to the electrode sheet 13; at the same time, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 controls each control switch 54 in a group of control switches 54 electrically connected to the electrode sheet 13 to be turned on in sequence at different times. At this time, the temperature detection signals collected by the respective temperature detection units 35 corresponding to each electrode unit 33 in each row group of the electrode sheet 13 can be collected in sequence at different times through the plurality of detection channels A, B, C, D, and E of a group of ADC units 52 corresponding to the electrode sheet 13. Each detection channel A, B, C, D, and E of each group of ADC units 52 only collects the temperature detection signals of the temperature detection units 35 corresponding to the electrode units 33 in the same row group of the electrode sheet 13 at the same time. The above temperature detection signals can be characterized by voltage values. Only 1 of the 4 control switches 54 in a group of control switches 54 corresponding to the electrode sheet 13 can be turned on at the same moment, and the other 3 are turned off. All 5 two-way switches 55 in a group of two-way switches 55 corresponding to the group of ADC units 52 are switched to their respective 1-ends, so that each two-way signal line 19 of the electrode sheet 13 is electrically connected to the corresponding detection channels A, B, C, D, and E of the corresponding ADC unit 52 in a one-to-one correspondence and turned on. With such a setting, the group of ADC units 52 can collect the voltage values of all the temperature detection units 35 corresponding to the electrode units 33 in the same row group short-circuited to a ground wire 18 corresponding to the turned-on control switch 54.

[0139] Specifically, when the control switch 54-1 is closed, the control switches 54-2, 54-3, and 54-4 are all open, and the first double-throw switch 55-1, the second double-throw switch 55-2, the third double-throw switch 55-3, the fourth double-throw switch 55-4, and the fifth double-throw switch 55-5 are all switched to their respective terminal 1, the temperature detection units 35 corresponding to the electrode units 33-1 to 33-5 in the first row group are powered on, and the temperature detection units 35 corresponding to the electrode units 33-6 to 33-20 in the remaining row groups are powered off. The signal terminals 35-2 of the temperature detection units 35 corresponding to the electrode units 33-1, 33-6, 33-11, and 33-16 are short-circuited on the first detection channel A of the group of ADC units 52. Since only the signal terminal 35-2 of the temperature detection unit 35 corresponding to the electrode unit 33-1 is conductively grounded, and the ground terminals 35-1 of the temperature detection units 35 corresponding to the electrode units 33-6, 33-11, and 33-16 are all open, and each temperature detection unit 35 includes a temperature sensor 34 and a diode 36 connected in series with the temperature sensor 34, the resistance value of the temperature detection unit 35 corresponding to the electrode unit 33-1 is not affected. Therefore, only the temperature detection unit 35 corresponding to the electrode unit 33-1 operates effectively on the first detection channel A of the group of ADC units 52, 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. Similarly, the voltage value collected on the second detection channel B of the group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-2. The voltage value collected on the third detection channel C of the group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-3. The voltage value collected on the fourth detection channel D of the group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-4. The voltage value collected on the fifth detection channel E of the ADC unit 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-5.

[0140] When the control switch 54-2 is closed, the control switches 54-1, 54-3 and 54-4 are all open, and the first double-throw switch 55-1, the second double-throw switch 55-2, the third double-throw switch 55-3, the fourth double-throw switch 55-4 and the fifth double-throw switch 55-5 are all switched to their respective terminal 1, the temperature detection units 35 corresponding to the electrode units 33-6 to 33-10 in the second row group are energized, and the temperature detection units 35 corresponding to the electrode units 33-1 to 33-5 and the electrode units 33-11 to 33-20 in the remaining row groups are de-energized. The signal terminals 35-2 of the temperature detection units 35 corresponding to the electrode units 33-1, 33-6, 33-11 and 33-16 are short-circuited on the first detection channel A of the group of ADC units 52. Since only the ground terminal 35-1 of the temperature detection unit 35 corresponding to the electrode unit 33-6 is conductively grounded, and the ground terminals 35-1 of the temperature detection units 35 corresponding to the electrode units 33-1, 33-11 and 33-16 are all open, and each temperature detection unit 35 includes a temperature sensor 34 and a diode 36 connected in series with the temperature sensor 34, the resistance value of the temperature detection unit 35 corresponding to the electrode unit 33-6 will not be affected. Therefore, only the temperature detection unit 35 corresponding to the electrode unit 33-6 operates effectively on the first detection channel A of the group of ADC units 52. At this time, the temperature detection signal (voltage value) collected on the first detection channel A is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-6. Similarly, the voltage value collected on the second detection channel B of the group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-7. The voltage value collected on the third detection channel C of the group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-8. The voltage value collected on the fourth detection channel D of the group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-9. The voltage value collected on the fifth detection channel E of the group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-10.

[0141] When the control switch 54-3 is closed, the control switches 54-1, 54-2 and 54-4 are all open, and when the first double-way changeover switch 55-1, the second double-way changeover switch 55-2, the third double-way changeover switch 55-3, the fourth double-way changeover switch 55-4 and the fifth double-way changeover switch 55-5 are all switched to their respective terminal 1, the temperature detection units 35 corresponding to the electrode units 33-11 to 33-15 of the third row group are powered on, and the temperature detection units 35 corresponding to the electrode units 33-1 to 33-10 and the electrode units 33-16 to 33-20 of the remaining row groups are powered off. On the first detection channel A of this group of ADC units 52, the signal terminals 35-2 of the temperature detection units 35 corresponding to the electrode units 33-1, 33-6, 33-11 and 33-16 are short-circuited. Since only the grounding terminal 35-1 of the temperature detection unit 35 corresponding to the electrode unit 33-11 is conductively grounded, while the grounding terminals 35-1 of the temperature detection units 35 corresponding to the electrode units 33-1, 33-6 and 33-16 are all open, and each temperature detection unit 35 includes a temperature sensor 34 and a diode 36 connected in series with the temperature sensor 34, the resistance value of the temperature detection unit 35 corresponding to the electrode unit 33-11 will not be affected. Therefore, only the temperature detection unit 35 corresponding to the electrode unit 33-11 operates effectively on the first detection channel A of this group of ADC units 52. At this time, the temperature detection signal (voltage value) collected on the first detection channel A is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-11. Similarly, the voltage value collected on the second detection channel B of this group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-12. The voltage value collected on the third detection channel C of this group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-13. The voltage value collected on the fourth detection channel D of this group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-14. The voltage value collected on the fifth detection channel E of this group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-15.

[0142] When the control switch 54-4 is closed, the control switches 54-1, 54-2 and 54-3 are all open, and the first bidirectional switch 55-1, the second bidirectional switch 55-2, the third bidirectional switch 55-3, the fourth bidirectional switch 55-4 and the fifth bidirectional switch 55-5 are all switched to their respective terminal 1, the temperature detection units 35 corresponding to the electrode units 33-16 to 33-20 in the fourth row group are powered on, and the temperature detection units 35 corresponding to the electrode units 33-1 to 33-15 in the remaining row groups are powered off. The signal terminals 35-2 of the temperature detection units 35 corresponding to the electrode units 33-1, 33-6, 33-11 and 33-16 are short-circuited on the first detection channel A of the group of ADC units 52. Since only the ground terminal 35-1 of the temperature detection unit 35 corresponding to the electrode unit 33-16 is conducting to the ground, and the ground terminals 35-1 of the temperature detection units 35 corresponding to the electrode units 33-1, 33-6 and 33-11 are all open, and each temperature detection unit 35 includes a temperature sensor 34 and a diode 36 connected in series with the temperature sensor 34, the resistance value of the temperature detection unit 35 corresponding to the electrode unit 33-16 will not be affected. Therefore, only the temperature detection unit 35 corresponding to the electrode unit 33-16 operates effectively on the first detection channel A of the group of ADC units 52. At this time, the temperature detection signal (voltage value) collected on the first detection channel A is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-16. Similarly, the voltage value collected on the second detection channel B of the group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-17. The voltage value collected on the third detection channel C of the group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-18. The voltage value collected on the fourth detection channel D of the group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-19. The voltage value collected on the fifth detection channel E of the group of ADC units 52 is the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-20.

[0143] 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 the electrode units 33 of a certain electrode plate 13 by controlling a group of bidirectional switching switches 55 and a group of control switches 54 that are all electrically connected to the electrode plate 13. That is, a switching unit (not labeled) is configured to switch the dual-purpose signal lines 19 corresponding to at least two column groups to be simultaneously connected to corresponding temperature sampling points (not labeled), and by configuring the switch states of the corresponding control switches 54, the temperature detection signals detected by the corresponding temperature detection units 35 in each row group are respectively sampled based on the corresponding temperature sampling points (not labeled). Similarly, the temperature detection signals of the temperature detection units 35 of the electrode units 33 of other electrode plates 13 can be obtained.

[0144] The first controller 51 or the second controller 37, multiple groups of ADC units 52, and multiple groups of bidirectional switching switches 55 can automatically execute operations through pre-programmed program codes. For example, the first controller 51 or the second controller 37 first controls all the bidirectional switching switches 55 in the corresponding group of bidirectional switching switches 55 to be switched to the 1 end, so that the 1 ends of these bidirectional switching switches 55 are all turned on and the 2 ends are all turned off, so that the dual-purpose signal lines 19 of the corresponding electrode plate 13 are electrically connected to the corresponding group of ADC units 52. Then, the control switch 54-1 in the corresponding group of control switches 54 is closed, and the remaining control switches 54-2 to 54-4 in this group of control switches 54 are opened. During this period, each detection channel A, B, C, D, E of this group of ADC units 52 obtains the temperature detection signals of the temperature detection units 35 corresponding to the electrode units 33 in the first row group of the corresponding electrode plate 13, converts them into digital signals, and stores them in a separately provided memory. Then, after a preset time interval, the first controller 51 or the second controller 37 closes the control switch 54-2 in this group of control switches 54, and opens the control switch 54-1, the control switch 54-3, and the control switch 54-4 in this group of control switches 54. During this period, each detection channel A, B, C, D, E of this group of ADC units 52 obtains the temperature detection signals of the temperature detection units 35 corresponding to the electrode units 33 in the second row group. In this way, by sequentially and separately turning on each control switch 54 in this group of control switches 54, the temperature detection signals of all the temperature detection units 35 on the electrode plate 13 can be obtained. Similarly, through this operation, the temperature detection signals of all the temperature detection units 35 on at least a pair of electrode plates 13 can be obtained.

[0145] It should be noted that in some other embodiments, the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 can also be used to control a group of bidirectional switches 55 and a group of control switches 54 electrically connected to a certain electrode plate 13 to collect the temperature detection signals of the temperature detection units 35 corresponding to some electrode units 33 of the electrode plate 13 during the same temperature acquisition period. For example, when only the first bidirectional switch 55-1 is switched to its terminal 1, the control switch 54-1 can be first controlled to close, and the control switches 54-2, 54-3, and 54-4 are all opened. At this time, only the temperature detection unit 35 corresponding to the electrode unit 33-1 in the first row group is powered on, and the signal terminal 35-2 of the temperature detection unit 35 corresponding to the electrode unit 33-1 in the first row group is short-circuited on the first detection channel A of the group of ADC units 52. Therefore, the group of ADC units 52 will detect the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-1. Then, the control switch 54-2 is controlled to close, and the control switches 54-1, 54-3, and 54-4 are all opened. At this time, the group of ADC units 52 will detect the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-6. Then, the control switch 54-3 is controlled to close, and the control switches 54-1, 54-2, and 54-4 are all opened. At this time, the group of ADC units 52 will detect the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-11. Finally, the control switch 54-4 is controlled to close, and the control switches 54-1, 54-2, and 54-3 are all opened. At this time, the group of ADC units 52 will detect the voltage value of the temperature detection unit 35 corresponding to the electrode unit 33-16. Thus, during the same acquisition period, only the temperature detection signals of the temperature detection units 35 corresponding to a column group of electrode units 33 can be sampled. Similarly, during other acquisition periods, the temperature detection signals of the temperature detection units 35 corresponding to other column groups of electrode units 33 can be sampled. That is, the switching unit (not labeled) is configured to switch the dual-purpose signal lines 19 corresponding to each column group to be respectively connected to the corresponding temperature sampling points (not labeled), and by configuring the switch states of the control switches 54, the temperature detection signals detected by each temperature detection unit 35 in each column group are respectively sampled. It should be noted that in some other embodiments, the temperature detection signals of the temperature detection units 35 corresponding to two column groups, three column groups, or four column groups of electrode units 33 can also be sampled during the same acquisition period, which will not be elaborated in detail here.

[0146] Specifically, when an alternating electric signal needs to be applied 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 each two-way switch 55 of a group of two-way switches 55 electrically connected to the electrode sheet 13 to conduct at its terminal 2 and disconnect at its terminal 1, and controls a power supply switch 40 electrically connected to the electrode sheet 13 to conduct. At this time, the second controller 37 of the electric field generator 30 controls the alternating current signal generator 39 to apply an alternating electric signal to each electrode unit 33 of the electrode sheet 13 through the alternating power supply line 57, and the magnitude of the voltage or current of the applied alternating electric signal is adjustable. That is, the switching unit (not labeled) is configured to switch the dual-purpose signal lines 19 corresponding to at least two column groups to be simultaneously connected to the alternating power supply line 57, so that the electrode units 33 of at least two column groups are simultaneously applied with an alternating electric signal based on the alternating power supply line 57.

[0147] It should be noted that in some other embodiments, it is also possible to control a group of two-way switches 55 electrically connected to a certain electrode sheet 13 through the first controller 51 of the adapter 20 or the second controller 37 of the electric field generator 30 to apply an alternating electric signal to some 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 two-way switch 55-1 of a group of two-way switches 55 electrically connected to the electrode sheet 13 to conduct at its terminal 2 and disconnect at its terminal 1, and controls a power supply switch 40 electrically connected to the electrode sheet 13 to conduct. At this time, the second controller 37 of the electric field generator 30 controls the alternating current signal generator 39 to apply an alternating electric signal to the first column group electrode units 33-1, 33-6, 33-11, and 33-16 of the electrode sheet 13 through the alternating power supply line 57, and the magnitude of the voltage or current of the applied alternating electric signal is adjustable. That is, the switching unit (not labeled) is configured to switch the dual-purpose signal lines 19 corresponding to each column group to be respectively connected to the alternating power supply line 57, so that the electrode units 33 of each column group are simultaneously applied with an alternating electric signal based on the alternating power supply line 57. It should be noted that in some other embodiments, it is also possible to apply an alternating electric signal to two column groups, three column groups, or four column groups of electrode units 33 simultaneously in the same time period, and the details are not elaborated here.

[0148] It should be noted that in the embodiments of the present application, the control switch 54 electrically connected to each of the multiple ground wires 18 of the electrode sheet 13 and the bidirectional switching 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 ground wire 18 and the bidirectional switching switch 55 electrically connected to the dual-purpose signal line 19 may also be provided on the electrode sheet 13 or in the electric field generator 30, which will not be elaborated 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.

[0149] The tumor electric field treatment system 100 of the present application can realize real-time and comprehensive monitoring of the temperatures of all the electrode units 33 on the electrode sheet 13 without increasing the weight of the electrode sheet 13 or the cores of the first cables 15 electrically connected to the electrode sheet 13. Furthermore, it can judge whether the electrode sheet 13 is qualified based on the obtained temperature detection signals; or it can judge whether there are faults or abnormalities in the temperature detection unit 35 of the electrode sheet 13 based on the obtained temperature detection signals, and judge whether it is necessary to replace the electrode sheet 13 based on the number of temperature detection units 35 with faults or abnormalities; or it can identify the type of the electrode sheet based on the obtained temperature detection signals when the electrode sheet is qualified; or it can judge whether there is an over-temperature situation in the electrode units 33 of the electrode sheet 13 based on the obtained temperature detection signals when the electrode sheet is qualified, and then control the alternating electric signals applied to the electrode sheet 13 or the corresponding column electrode units 33 of the electrode sheet 13 to avoid low-temperature burns on the patient's body surface during tumor treatment through the electrode sheet 13. In addition, the substrate 31 of the electrode sheet 13 of the present application electrically connects the same electrode unit 33 and the signal terminal 35-2 of its corresponding temperature detection unit 35 through the same dual-purpose signal line 19 arranged thereon. While enabling the dual-purpose signal line 19 to transmit both alternating electric signals and direct current signals for temperature signal acquisition and the acquired temperature detection signals, it also greatly reduces the number of conductive traces (ground wires 18, dual-purpose signal lines 19) arranged thereon, reduces the wiring difficulty of the substrate 31, simplifies the manufacturing process, reduces the weight of the substrate 31, and reduces the manufacturing cost. The electrode sheet 13 of the present application can also be switched between applying alternating electric 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 ground wire 18 arranged thereon and the bidirectional switching switch 55 electrically connected to the dual-purpose signal line 19.

[0150] Specifically, when it is necessary to apply an alternating electric signal to the patient through the electrode units 33 of a certain electrode patch 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 patch 13, and at the same time controls to switch all the bidirectional switches 55 in a group of bidirectional switches 55 corresponding to the electrode patch 13 to their 2 ends, so that the 1 ends of these bidirectional switches 55 are all disconnected and the 2 ends are all conducted, realizing that each two-way signal line 19 of the electrode patch 13 is electrically connected to an alternating power supply line 57 corresponding to the adapter 20 and the electrode patch 13, thereby transmitting the alternating electric signal to the electrode units 33 of the electrode patch 13.When the temperature detection signals of all the temperature detection units 35 corresponding to the electrode units 33 of the detected electrode sheet 13 are much lower than the preset temperature threshold stored in the electric field generator 30 or the adapter 20, the electric field generator 30 controls the AC signal generator 39 to continue generating an alternating current signal with an increasing voltage or current amplitude, or a constant voltage or current amplitude through its second controller 37, and then transmits it to the corresponding pair of electrode sheets 13 through a corresponding alternating power line 57 of the adapter 20, so as to continue applying the alternating current signal to the pair of electrode sheets 13; when the temperature detection signals of all the temperature detection units 35 corresponding to the electrode units 33 of the detected electrode sheet 13 are lower than but close to the preset temperature threshold stored in the electric field generator 30 or the adapter 20, the electric field generator 30 can reduce the voltage or current of the alternating current signal generated by the AC signal generator 39 through the second controller 37, and then reduce the voltage or current of the alternating current signal applied to the pair of electrode sheets 13; when it is detected that the temperature detection signal of a temperature detection unit 35 corresponding to an electrode unit 33 of a certain electrode sheet 13 is greater than the 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 current signal to the electrode sheet 13; or the second controller 37 of the electric field generator 30 or the first controller 21 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 their 1 ends, that is, controls all the 1 ends of the group of bidirectional switches 55 electrically connected to the electrode sheet 13 to be turned on and all the 2 ends to be disconnected, so as to stop applying the alternating current signal to the electrode sheet 13; or, when it is detected that the temperature detection signal of a temperature detection unit 35 corresponding to an electrode unit 33 of a certain electrode sheet 13 is greater than the preset temperature threshold, the second controller 37 of the electric field generator 30 controls the power supply 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 21 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 2 end to its 1 end, and at the same time, the second controller 37 of the electric field generator 30 or the first controller 21 of the adapter 20 controls the remaining bidirectional switches 55 electrically connected to the electrode units 33 whose temperature detection signals do not exceed the preset temperature threshold and are in different columns from the electrode units 33 whose temperature detection signals exceed the preset temperature threshold of the electrode sheet 13 to continue to be electrically connected to their respective 2 ends, so as to stop applying the alternating current signal to all the electrode units 33 in the column where the electrode units 33 with temperature detection signals exceeding the preset temperature threshold of the electrode sheet 13 are located, and continue to apply the alternating current signal to the remaining column electrode units 33 of the electrode sheet 13 whose temperature detection signals do not exceed the preset temperature threshold. Thus, a method for controlling the application of an alternating current signal based on a temperature detection signal in the tumor electric field treatment system 100 is realized.

[0151] An embodiment of the present application provides a method for detecting the temperature of an electrode sheet, which is applied to the above-mentioned electrode sheet 13 or the tumor electric field therapy system 100. Referring to Figure 8 as shown, it includes the following steps:

[0152] Step 210: Control the switching unit to connect at least one column group corresponding dual-purpose signal line 19 in the corresponding electrode sheet 13 to the corresponding temperature sampling point.

[0153] Specifically, control the bidirectional switching switch 55 electrically connected to each electrode unit 33 of the electrode sheet 13 to disconnect the alternating current signal applied to each electrode unit 33 of the electrode sheet 13 and simultaneously connect the direct current signal to the signal terminal 35-2 of the temperature detection unit 35 applied to each electrode unit 33 of the electrode sheet 13.

[0154] Further, control the bidirectional switching switch 55 electrically connected to each electrode unit 33 of the electrode sheet 13 to switch from the end electrically connected to the alternating current signal to the end electrically connected to the direct current signal, that is, control the bidirectional switching switch 55 electrically connected to the electrode sheet 13 to switch from its 2 end to its 1 end; or, control the bidirectional switching switch 55 electrically connected to each electrode unit 33 of the electrode sheet 13 to switch each electrode unit 33 of the electrode sheet 13 from the conducting state to the disconnected state and simultaneously switch the signal terminal 35-2 of the temperature detection unit 35 of each electrode unit 33 of the electrode sheet 13 from the disconnected state to the conducting state.

[0155] Step 220: Control the control switch 54 corresponding to each row group to sample the analog temperature signal of the corresponding electrode unit 33 based on the corresponding temperature sampling point.

[0156] Specifically, sequentially turn on 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 to obtain the temperature detection signal of the temperature detection unit 35 of each electrode unit 33 of the electrode sheet 13.

[0157] In some embodiments, when the dual-purpose signal lines 19 corresponding to each column group are respectively connected to the corresponding temperature sampling points, controlling the control switch 54 corresponding to each row group includes: controlling the control switch 54 corresponding to each row group to be closed in sequence to sample the analog temperature signals of each electrode unit 33 in each column group respectively.

[0158] In other embodiments, when the dual-purpose signal lines 19 corresponding to at least two column groups are simultaneously connected to the corresponding temperature sampling points, controlling the control switch 54 corresponding to each row group includes: controlling the control switch 54 corresponding to each row group to be closed in sequence to sample the analog temperature signals of the corresponding electrode units 33 in each row group respectively.

[0159] By using the electrode sheet temperature detection method of the present application, the temperatures of all electrode units of the electrode sheet can be obtained quickly and accurately; and based on the temperature detection signals of all temperature detection units of the obtained electrode sheet, it can be determined whether there are faults or abnormalities in the temperature detection units of the electrode sheet, or whether the electrode sheet is qualified or needs to be replaced; it can also, when the temperature detection units of the electrode sheet are normal, based on the temperature detection signals of all temperature detection units of the obtained electrode sheet, determine whether there is overheating in each electrode unit of the electrode sheet and then control the alternating current signal applied to the electrode sheet or each electrode unit of the electrode sheet; it can also identify the type of the electrode sheet when the temperature detection signals of the temperature detection units of the electrode sheet are normal.

[0160] In the adapter 20 or the electric field generator 30 of the tumor electric field treatment system 100 according to an embodiment of the present application, a preset threshold, a first preset temperature, a second preset temperature, and a preset temperature threshold are provided, where the first preset temperature is lower than the second preset temperature, and the second preset temperature is lower than the preset temperature threshold.

[0161] Referring to Figure 9 As shown, the present application also provides an electrode sheet temperature abnormality detection method, which includes the following steps:

[0162] Step 210: Control the switching unit to connect at least one column group corresponding dual-purpose signal line 19 in the corresponding electrode sheet 13 to the corresponding temperature sampling point.

[0163] Step 220: Control the control switch 54 corresponding to each row group to sample the analog temperature signal of the corresponding electrode unit 33 based on the corresponding temperature sampling point, so as to determine the temperature detection signal of each electrode unit 33 in each electrode sheet 13.

[0164] Step 230: Determine whether the electrode sheet 13 is abnormal according to the temperature detection signal.

[0165] 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:

[0166] Step 231: Compare the temperature at each electrode unit 33 in the corresponding electrode sheet 13 with the preset temperature threshold according to the temperature detection signal. Specifically, the temperature detection signal detected by the temperature detection unit 35 corresponding to each electrode unit 33 in the obtained electrode sheet 13 can be compared with the preset temperature threshold.

[0167] Step 232: Determine whether the temperature of the electrode sheet 13 is abnormal according to the comparison result. Specifically, determine whether there is temperature abnormality in each electrode unit 33 of the electrode sheet 13 according to the comparison result.

[0168] 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 lower than 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.

[0169] The process of determining whether the temperature of the electrode sheet 13 is abnormal according to the comparison result in step 232 is specifically as follows: When the temperature at any one electrode unit 33 in the corresponding electrode sheet 13 exceeds the preset temperature threshold, it is determined that the temperature of the electrode sheet 13 is abnormal. And when the temperatures at all electrode units 33 in the corresponding electrode sheet 13 do not exceed the preset temperature threshold, it is determined that the temperature of the electrode sheet 13 is not abnormal.

[0170] In some other embodiments, the process of determining whether the electrode sheet 13 is abnormal according to the temperature detection signal in step 230 specifically includes the following steps:

[0171] Step 233: When it is determined according to the temperature detection signal that any one electrode unit 33 in the corresponding electrode sheet 13 is abnormal or fails, it is determined that the electrode sheet 13 is unqualified.

[0172] Specifically, according to the obtained temperature detection signals detected by the temperature detection units 35 corresponding to the respective electrode units 33 in the electrode sheet 13, it is determined whether the temperature detection units 35 corresponding to the respective electrode units 33 in the electrode sheet 13 are abnormal or have failed; then, according to whether the temperature detection units 35 corresponding to the respective electrode units 33 in the electrode sheet 13 are abnormal or have failed, it is determined whether the electrode sheet 13 is qualified. Among them, when the temperature detection units 35 corresponding to the respective electrode units 33 in the electrode sheet 13 are abnormal or have failed, it is determined that the electrode sheet 13 is unqualified; when the temperature detection units 35 corresponding to the respective electrode units 33 in the electrode sheet 13 are not abnormal or have not failed, it is determined that the electrode sheet 13 is qualified.

[0173] In still some other embodiments, the process of determining whether the electrode sheet 13 is abnormal according to the temperature detection signal in step 230 specifically includes the following steps:

[0174] Step 234: When it is determined according to the temperature detection signal that there is an abnormal or failed electrode unit 33 in the corresponding electrode sheet 13, determine the number of abnormal or failed electrode units 33.

[0175] Step 235: When the number of abnormal or failed electrode units 33 reaches the preset threshold, it is determined that the electrode sheet 13 needs to be replaced.

[0176] Specifically, based on the temperature detection signals of the temperature detection units 35 corresponding to the respective electrode units 33 in the obtained electrode sheet 13, it is determined whether there is an abnormality or a failure in the temperature detection units 35 corresponding to the respective electrode units 33 in the electrode sheet 13; then, based on whether there is an abnormality or a failure in the temperature detection units 35 corresponding to the respective electrode units 33 in the electrode sheet 13, it is determined whether the electrode sheet 13 needs to be replaced.

[0177] For example, when there is an abnormality or a failure in the temperature detection units 35 corresponding to the respective electrode units 33 in the electrode sheet 13 and the number of temperature detection units 35 with the abnormality or the failure exceeds a preset threshold, it is determined that the electrode sheet 13 needs to be replaced; when the number of temperature detection units 35 with the abnormality or the failure in the electrode sheet 13 does not exceed the preset threshold, it is determined that the electrode sheet 13 does not need to be replaced. Among them, the preset threshold is 20% of the total number of all temperature detection units 35 of the electrode sheet 13.

[0178] Refer to Figure 10 As shown, the present application also provides a control method for a tumor electric field treatment system, which includes the following steps:

[0179] Step 210: Control the switching unit to connect at least one column group corresponding to the dual-purpose signal lines 19 in the corresponding electrode sheet 13 to the corresponding temperature sampling points.

[0180] Step 220: Control the control switches 54 corresponding to each row group, so as to sample the analog temperature signals of the corresponding electrode units 33 based on the corresponding temperature sampling points, and determine the temperature detection signals of the respective electrode units 33 in each electrode sheet 13.

[0181] Step 240: Control the intensity of the alternating electric signal applied to the electrode unit 33 according to the temperature detection signal.

[0182] Specifically, in the case where it is determined that the electrode sheet 13 does not need to be replaced, control or adjust the alternating electric signals applied to the respective electrode units 33 in the electrode sheet 13 according to the temperature detection signals detected by the temperature detection units 35 corresponding to the respective electrode units 33 in the obtained electrode sheet 13. That is to say, steps 234-235 can be added between step 240 and step 220.

[0183] In some embodiments, the control of the intensity of the alternating electric signal applied to the electrode unit 33 according to the temperature detection signal in step 240 specifically includes the following steps:

[0184] Step 241: Compare the temperature at each electrode unit 33 in the electrode sheet 13 with a preset temperature threshold according to the temperature detection signal.

[0185] Step 242: Control the intensity of the alternating electric signal according to the comparison result.

[0186] In some embodiments, the control of the AC signal intensity according to the comparison result in step 242 specifically includes:

[0187] Step 2421: When the temperature at at least one electrode unit 33 exceeds a preset temperature threshold, stop applying the AC signal to the electrode unit 33 of the electrode sheet 13. Specifically, when there is a temperature detection signal exceeding the preset temperature threshold among the temperature detection signals of all electrode units 33 of the obtained electrode sheet 13, stop applying the AC signal to the electrode unit 33 of the electrode sheet 13. And when the temperature detection signals of each electrode unit 33 in the obtained electrode sheet 13 do not exceed the preset temperature threshold, continue to apply the AC signal to each electrode unit 33 of the electrode sheet 13.

[0188] In some embodiments, the stopping of applying the AC signal to the electrode unit 33 of the electrode sheet 13 in step 2421 specifically includes: stopping applying the AC signal to all electrode units 33 of the electrode sheet 13; or stopping applying the AC signal to all electrode units 33 of the column group where the electrode unit 33 exceeding the preset temperature threshold in the electrode sheet 13 is located.

[0189] Further, in the case of stopping applying the AC signal to all electrode units 33 of the column group where the electrode unit 33 exceeding the preset temperature threshold in the electrode sheet 13 is located, continue to apply the AC signal to the electrode units 33 of other column groups in the electrode sheet 13. Among them, the intensity of the AC signal applied to the electrode units 33 of other column groups in the electrode sheet 13 is adjustable. For example, all electrode units 33 in the electrode sheet 13 whose temperature detection signals do not exceed the preset temperature threshold and are in different columns from the electrode units 33 whose temperature detection signals exceed the preset temperature threshold continue to be applied with the AC signal, and this signal is adjustable.

[0190] In other embodiments, the control of the AC signal intensity according to the comparison result in step 242 specifically includes:

[0191] 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 AC signal applied to the electrode units 33 of the electrode sheet 13, where the first preset temperature is less than the preset temperature threshold.

[0192] In step 2422, the increase amplitude of the electric field intensity corresponding to each column group where the AC signal intensity is increased is the same.

[0193] Step 2423: When the temperatures at all the electrode units 33 in the electrode sheet 13 do not exceed the preset temperature threshold, if there is at least one electrode unit 33 in the electrode sheet 13 where the temperature exceeds the first preset temperature and is less than the preset temperature threshold, keep the intensity of the alternating electric signal applied to the electrode units 33 of the electrode sheet 13 unchanged.

[0194] Step 2424: When the temperatures at all the electrode units 33 in the electrode sheet 13 do not exceed the preset temperature threshold, if there is at least one electrode unit 33 in the electrode sheet 13 where the temperature exceeds the second preset temperature and is less than the preset temperature threshold, reduce the intensity of the alternating electric signal applied to the electrode units 33 of the electrode sheet 13, where the second preset temperature is greater than the first preset temperature and less than the preset temperature threshold.

[0195] In step 2424, the reduction amplitude of the electric field intensity corresponding to each column group where the intensity of the alternating electric signal is reduced is the same.

[0196] Exemplarily, when the temperature detection signal is much lower than the preset temperature threshold, continue to apply the alternating electric signal to the electrode units 33 of the electrode sheet 13 by increasing the voltage or current amplitude of the alternating electric signal applied to the electrode units 33 of the electrode sheet 13, or continue to apply the alternating electric signal to the electrode units 33 of the electrode sheet 13 by keeping the voltage or current amplitude of the alternating electric signal applied to the electrode units 33 of the electrode sheet 13 unchanged. When the temperature detection signal is close to the preset temperature threshold, continue to apply the alternating electric signal to the electrode units 33 of the electrode sheet 13 by keeping the voltage or current amplitude of the alternating electric signal applied to the electrode units 33 of the electrode sheet 13 unchanged, or continue to apply the alternating electric signal to the electrode units 33 of the electrode sheet 13 by reducing the voltage or current amplitude of the alternating electric signal applied to the electrode units 33 of the electrode sheet 13.

[0197] In some other embodiments, the control of the intensity of the alternating electric signal according to the comparison result in step 242 specifically includes:

[0198] Step 2425: When the temperature at at least one electrode unit 33 exceeds the preset temperature threshold, determine the number of over-temperature column groups.

[0199] Step 2426: When the number of over-temperature column groups exceeds the preset number threshold, stop applying the alternating electric signal to all the electrode units 33 of the electrode sheet 13.

[0200] Step 2427: When the number of over-temperature column groups does not exceed the preset number threshold, stop applying the alternating electric signal to all the electrode units 33 in the column group where the electrode units 33 exceeding the preset temperature threshold are located in the electrode sheet 13.

[0201] Further, when stopping applying the alternating current signal to all the electrode units 33 in the column group where the electrode unit 33 in the electrode sheet 13 exceeds the preset temperature threshold, continue to apply the alternating current signal to the electrode units 33 in other column groups of the electrode sheet 13. Wherein, the intensity of the alternating current signal applied to the electrode units 33 in other column groups of the electrode sheet 13 is adjustable.

[0202] Step 2428: When the number of over-temperature column groups does not exceed the preset number threshold, if the temperature at each electrode unit 33 in the non-over-temperature column groups does not exceed the first preset temperature, increase the intensity of the alternating current signal applied to the electrode units 33 in the non-over-temperature column groups, wherein the first preset temperature is less than the preset temperature threshold.

[0203] In step 2428, the increase amplitude of the electric field intensity corresponding to each column group where the intensity of the alternating current signal increases is the same.

[0204] Step 2429: When the number of over-temperature column groups does not exceed the preset number threshold, if there is at least one electrode unit 33 in the non-over-temperature column groups where the temperature exceeds the first preset temperature and is less than the preset temperature threshold, keep the intensity of the alternating current signal currently applied to the electrode units 33 in the non-over-temperature column groups unchanged.

[0205] Step 2430: When the number of over-temperature column groups does not exceed the preset number threshold, if there is at least one electrode unit 33 in the non-over-temperature column groups where the temperature exceeds the second preset temperature and is less than the preset temperature threshold, decrease the intensity of the alternating current signal applied to the electrode units 33 in the non-over-temperature column groups, wherein the second preset temperature is greater than the first preset temperature and less than the preset temperature threshold.

[0206] In step 2430, the decrease amplitude of the electric field intensity corresponding to each column group where the intensity of the alternating current signal decreases is the same.

[0207] Exemplarily, when the temperature detection signal is much lower than the preset temperature threshold, continue to apply the alternating current signal to each electrode unit 33 of the electrode sheet 13 by increasing the voltage or current amplitude of the alternating current signal applied to each electrode unit 33 of the electrode sheet 13, or continue to apply the alternating current signal to each electrode unit 33 of the electrode sheet 13 by keeping the voltage or current amplitude of the alternating current signal applied to each electrode unit 33 of the electrode sheet 13 unchanged. When the temperature detection signal is close to the preset temperature threshold, continue to apply the alternating current signal to each electrode unit 33 of the electrode sheet 13 by keeping the voltage or current amplitude of the alternating current signal applied to each electrode unit 33 of the electrode sheet 13 unchanged, or continue to apply the alternating current signal to each electrode unit 33 of the electrode sheet 13 by decreasing the voltage or current amplitude of the alternating current signal applied to each electrode unit 33 of the electrode sheet 13.

[0208] Reference Figure 11 As shown, the present application also provides a method for identifying the type of electrode sheet, which includes the following steps:

[0209] Step 210: Control the switching unit to connect at least one column group corresponding dual-purpose signal line 19 in the corresponding electrode sheet 13 to the corresponding temperature sampling point.

[0211] Step 250: Identify the type of the electrode sheet 13 according to the temperature detection signal.

[0212] 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 according to the temperature detection signal detected by each temperature detection unit 35 of each electrode unit 33 in the obtained electrode sheet 13.

[0213] 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: combinatorially 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.

[0214] Reference Figure 12 As shown, the present application also provides a signal control method for tumor electric field therapy, which is used for the above-mentioned electrode sheet 13. The method includes:

[0215] Step 310: Combinatorially control the control switch 54 and the bidirectional switching switch 55 electrically connected to the corresponding electrode sheet 13 to apply an alternating electric signal to each electrode unit 33 of the electrode sheet 13 and execute step 320;

[0216] Step 320: Combinatorially control the control switch 54 and the bidirectional switching switch 55 electrically connected to the electrode sheet 13 to collect the temperature detection signals of each electrode unit 33 of the electrode sheet 13 row by row and execute step 330;

[0217] Step 330: Determine the combined control mode of the control switch 54 and the bidirectional switching switch 55 electrically connected to the electrode sheet 13 according to the collected temperature detection signal and execute step 340;

[0218] 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 switching switch 55.

[0219] The working states of the electrode units 33 of the electrode sheet 13 in step 340 include at least one of: stopping applying the alternating current signal and continuing to collect the temperature detection signal, and stopping collecting the temperature detection signal and continuing to apply the alternating current signal. Continuing to apply the alternating current signal includes continuing to apply the alternating current signal in a manner of increasing the voltage or current amplitude of the currently applied alternating current signal, or continuing to apply the alternating current signal in a manner of keeping the voltage or current amplitude of the currently applied alternating current signal unchanged, or continuing to apply the alternating current signal in a manner of decreasing the voltage or current amplitude of the currently applied alternating current signal.

[0220] The working state of each electrode unit 33 of the electrode sheet 13 is determined by the temperature detection signal collected by it. Each electrode unit 33 of the electrode sheet 13 is divided into different regions, and through the combined control of the control switch 54 and the bidirectional switch 55, each electrode unit 33 in each region can be cyclically switched between applying the alternating current signal and collecting the temperature detection signal.

[0221] Another electrode sheet temperature detection method for the tumor electric field treatment system 100 is provided in an embodiment of the present application. Please refer to Figure 13 As shown, this temperature detection method includes:

[0222] Step 510: Disconnect the input of the alternating current signal of the electrode sheet 13, perform combined control on a plurality of control switches 54 and a plurality of bidirectional switches 55, and obtain the temperature detection signals of the temperature sensors 34 of the electrode sheet 13 corresponding to each combination in all combinations;

[0223] Step 520: Sample and convert the temperature detection signals detected by each temperature sensor 34 in the electrode sheet 13 to obtain digital temperature signals;

[0224] Step 530: Transmit the digital temperature signals to the electric field generator 30 of the tumor electric field treatment system 100, so that the electric field generator 30 determines the temperature at the corresponding electrode unit 33 according to the digital temperature signals.

[0225] In step 510, the combined control of a plurality of control switches 54 and a plurality of bidirectional switches 55 specifically includes:

[0226] Step 511: Place all the bidirectional switches 55 at the 1 end to conduct the electrical connection between the signal terminals 35-2 of the respective temperature detection units 35 corresponding to all electrode units 33 and the corresponding ADC units 52;

[0227] Step 512: Close one of the plurality of control switches 54 separately in sequence and time division to collect row by row the temperature detection signals detected by the respective temperature detection units 35 corresponding to the electrode units 33 in the corresponding row group.

[0228] In step 512, successively closing one of the multiple control switches 54 separately at different times can conduct the detection channels through which the ADC unit 52 is electrically connected to each temperature detection unit 35 in the row group corresponding to the closed control switch 54.

[0229] Thus, the temperature detection signals of the corresponding temperature detection units 35 in each row group can be obtained successively. Then, after being processed by the adapter 20 or the electric field generator 30, the temperatures corresponding to all electrode units 33 on the electrode patch 13 can be obtained, so as to make the temperature detection on the patient's body surface more comprehensive and accurate.

[0230] For the tumor electric field therapy system 100 according to the embodiment of the present application, the temperature of a single electrode unit 33 can also be detected as needed. The specific process of detecting the temperature of a certain electrode unit 33 on the electrode patch 13 is as follows: Disconnect the input of the alternating electric signal, place the bidirectional switching switch 55 corresponding to the column group where the electrode unit 33 to be separately temperature-measured is located at the 1 end, and place the remaining bidirectional switching switches 55 at the 2 end; at the same time, conduct and ground the control switch 54 corresponding to the row group where the electrode unit 33 to be separately temperature-measured is located, and disconnect all the remaining control switches 54. Thus, the temperature detection signal of the temperature detection unit 35 corresponding to the electrode unit 33 to be separately temperature-measured can be sampled to obtain the temperature of the electrode unit 33. For example, if the electrode unit 33 to be separately temperature-measured is the electrode unit 33-1, at this time, place the bidirectional switching switch 55-1 corresponding to the electrode unit 33-1 at the 1 end, and place all the remaining bidirectional switching switches (55-2 to 55-5) at the 2 end; at the same time, close and ground the control switch 18-1 corresponding to the electrode unit 33-1, and disconnect all the remaining control switches (18-2 to 18-4). Thus, the temperature of the electrode unit 33-1 can be detected.

[0238] Step 615: Control the bidirectional switching switches 55 electrically connected to the electrode units 33 that need to apply alternating electric signals to electrically connect the electrode units 33 that need to apply alternating electric signals to the alternating power supply line 57 to apply alternating electric signals; at the same time, control the remaining bidirectional switching switches 55 to disconnect the electrical connection between the electrode units 33 in the areas where alternating electric signals do not need to be applied and the alternating power supply line 57 to stop applying alternating electric signals.

[0239] In step 615, "electrically connect the electrode units that need to apply alternating electric signals to the alternating power supply line 57 to apply alternating electric signals and disconnect the electrical connection between the electrode units 33 in the areas where alternating electric signals do not need to be applied and the alternating power supply line 57 to stop applying alternating electric signals" is achieved by placing the bidirectional switching switches 55 electrically connected to the electrode units 33 in the column groups corresponding to the areas (1-5) where alternating electric signals need to be applied in the electrode sheet 13 at their 2 ends, and placing all the bidirectional switching switches 55 electrically connected to the electrode units 33 in the remaining column groups at their 1 ends.

[0378] The main concept of the above-mentioned tumor electric field therapy system 100 is that there is an alternating current power line 57 in both the adapter 20 and the electric field generator 30, which controls the synchronous change of the alternating current signals of all the electrode units 33 on one electrode plate 13, such as the voltage or current rising or falling simultaneously, and different alternating current signals cannot be applied to different column groups of electrode units 33 at the same time, such as voltages or currents of different magnitudes. Refer to Figures 17 to 20 Next, another tumor electric field therapy system 100' is described. Its main concept is the same as that of the above-mentioned tumor electric field therapy system 100, but the difference is that: for each column group of electrode units 33' on the corresponding electrode plate 13' in the adapter 20' and the electric field generator 30' of this tumor electric field therapy system 100', there is a corresponding alternating current power line 57', so that different alternating current signals can be applied to different column groups of electrode units 33' at the same time, such as voltages or currents of different magnitudes.

[0379] Figure 18Schematic diagram of the circuit connection of an electrode patch 13', an adapter 20' and an electric field generator 30' of another tumor electric field therapy system 100' according to an embodiment of the present application. The tumor electric field therapy system 100' includes: at least a pair of electrode patches 13', an adapter 20' connected to the electrode patch 13', and an electric field generator 30' connected to the adapter 20'.

[0380] Among them, the specific structure of the electrode patch 13' is the same as that of the above-mentioned electrode patch 13, and will not be elaborated here.

[0381] The specific structure of the adapter 20' is similar to that of the above-mentioned adapter 20, except that: referring to Figure 18 and Figure 19 , five alternating power supply lines 57' are provided in the adapter 20' corresponding to one electrode patch 13'. The five alternating power supply lines 57' are arranged in one-to-one correspondence with the five column group electrode units 33' of one electrode patch 13'. A corresponding bidirectional switching switch 55' and a grounding switch 54' are provided for each electrode patch 13'. Both ends of the bidirectional switching switch 55' are electrically connected to a separate alternating current power supply line 57', so that the tumor electric field therapy system 100' can apply different alternating current signals, such as different voltages or currents, to different column group electrode units 33' in each electrode patch 13' as needed.

[0382] The specific structure of the electric field generator 30' is similar to that of the above-mentioned electric field generator 30, except that: referring to Figure 18 and Figure 20 , a power supply switch 40' is provided for each alternating power supply line 57' between the alternating current signal generator 39' and the alternating power supply line 57' connected to the adapter 20' to independently control the on / off of the alternating current signal of each column group electrode unit 33' of each electrode patch 13'.

[0383] Specifically, referring to Figure 18 and Figure 19As shown, the adapter 20' includes: a first controller 51', multiple groups of ADC units 52' connected to the first controller 51', multiple groups of voltage dividing resistors 53' and multiple groups of control switches 54' corresponding to the multiple groups of ADC units 52' one by one, multiple groups of bidirectional switching switches 55' connected to the multiple groups of ADC units 52' one by one, a first communication unit 56', multiple groups of alternating power supply lines 57' connected to each group of bidirectional switching switches 55' one by one, and a first power supply module 58' connected to the first communication unit 56', the first controller 51' and the multiple groups of ADC units 52' at the same time. The first power supply module 58' provides a DC power supply VCC for each electronic component of the adapter 20'. The adapter 20' also includes multiple circuit lines (not labeled), and the multiple circuit lines (not labeled) are respectively and electrically connected to multiple ground lines 18' and multiple dual-purpose signal lines 19' in the substrate 31' of the corresponding electrode plate 13' through the first cable 15' of the corresponding electrode plate 13'. The multiple circuit lines (not labeled) include multiple different alternating power supply lines 57' that respectively transmit alternating current signals to the corresponding electrode plates 13' and are electrically connected to the multiple dual-purpose signal lines 19' in the substrate 31' of the corresponding electrode plates 13', multiple circuit lines (not labeled) that are respectively and electrically connected to the multiple dual-purpose signal lines 19' in the substrate 31' of the corresponding electrode plates 13' one by one and are used to supply power to each temperature detection unit 35' of the electrode plate 13' or transmit the temperature detection signal of the electrode plate 13', and multiple circuit lines (not labeled) that are respectively and electrically connected to the multiple ground lines 18' in the substrate 31' of the corresponding electrode plates 13' one by one. The number L of circuit lines of the adapter 20' electrically connected to an electrode plate 13' is equal to the sum of the number of rows and columns of the electrode units 33' of the electrode plate 13'; the number H of circuits of the adapter 20' electrically connected to X electrode plates 13' is X times the number of circuit lines of the adapter 20' electrically connected to a single electrode plate 13', that is, H = XL = X*(M + N). The number of groups of the control switches 54' and the number of groups of the bidirectional switching switches 55' are both related to the number of electrode plates 13'. The number of groups of the control switches 54' is the same as the number of groups of the bidirectional switching switches 55', and is not less than the number of electrode plates 13'. Optionally, the number of groups of the control switches 54' and the number of groups of the bidirectional switching switches 55' are both the same as the number of electrode plates 13'.

[0384] For example, each group of control switches 54’ is provided with a plurality of control switches 54’. The plurality of control switches 54’ are respectively connected into the adapter 20’ and are respectively electrically connected to circuit lines (not labeled) corresponding to the multi-way ground wires 18’ of a corresponding electrode plate 13’, and are configured to control the conduction or disconnection of the multi-way ground wires 18’. The circuit lines (not labeled) of the multi-way ground wires 18’ that are respectively and electrically connected to the electrode plate 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 ground wires 18’ of the substrate 31’ of the corresponding electrode plate 13’, and in this embodiment, the two are equal. As Figure 18 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’ and a fourth control switch 54-4’.

The above control switches 54’ can be mechanical switches, such as relays. The control switches 54’ can also be electronic switches, and each control switch 54’ can be opened and closed through an additional first controller 51’.

[0385] In this embodiment, multiple groups of control switches 54' are all electronic switches. The first controller 51' is communicatively connected to the multiple groups of control switches 54' and is configured to sequentially and cyclically control the opening and closing states of the multiple control switches 54' in each group of control switches 54', thereby sequentially and individually conducting each of the multiple ground wires 18' of the corresponding electrode plate 13' and cooperating with the switching of the corresponding bidirectional switching switch 55' to collect the temperatures of the patient's body surface detected by all the temperature detection units 35' on the electrode plate 13'. The number of control switches 54' in each group is not less than the number of ground wires 18' of the substrate 31' of the corresponding electrode plate 13'. In this embodiment, the number of control switches 54' in each group is the same as the number of ground wires 18' of the corresponding electrode plate 13'.

[0386] Each group of bidirectional switching switches 55' is provided with multiple bidirectional switching switches 55'. The multiple bidirectional switching switches 55' in each group are respectively connected into the adapter 20' and are respectively electrically connected to circuit lines (not labeled) corresponding to the multiple multi-purpose signal lines 19' of a corresponding electrode plate 13'. The number of bidirectional switching switches 55' in each group of bidirectional switching switches 55' is related to the number of multi-purpose signal lines 19' of the substrate 31' of the corresponding electrode plate 13', and is greater than or equal to the number of multi-purpose signal lines 19' of the substrate 31' of the corresponding electrode plate 13'. In this embodiment, the two are equal. Each bidirectional switching switch 55' has two ends labeled 1 and 2. The 1 ends of the multiple bidirectional switching switches 55' in the same group are respectively electrically connected to the corresponding detection channels of the multiple detection channels of a corresponding group of ADC units 52' through temperature sampling points (not labeled). The 2 ends of each bidirectional switching switch 55' in the same group are electrically connected to different alternating power supply lines 57', and are configured to control the multi-purpose signal lines 19' to be connected to different alternating power supply lines 57' to transmit alternating current signals or to be connected to the corresponding detection channels of the corresponding group of ADC units 52' to receive the temperature detection signals output by the temperature detection units 35'.

When the 2-end of each group of bidirectional switches 55' is conducting and the 1-end is disconnected, the alternating-current power signal can be transmitted to each electrode unit 33' of each column group of the corresponding electrode plate 13' through different alternating-current power lines 57'. When the 1-end of each group of bidirectional switches 55' is conducting and the 2-end is disconnected, it can cooperate with each control switch 54' in the corresponding group of control switches 54' to transmit the temperature detection signal collected by the temperature detection units 35' of each electrode element 33' on the electrode plate 13' in a time-sharing manner. The above bidirectional switch 55' can be a mechanical switch, such as a relay. The bidirectional switch 55' can also be an electronic switch, and each bidirectional switch 55' can be switched by an additional first controller 51'.

[0388] In this embodiment, multiple groups of bidirectional switches 55' are all electronic switches. The first controller 51' is communicatively connected to multiple groups of bidirectional switches 55' and is used to control the switching of multiple bidirectional switches 55' in each group of bidirectional switches 55' between their 1-ends and 2-ends, and cooperate with the closing or opening of the corresponding control switch 54' to continuously monitor the temperature of the patient's body surface detected by all temperature detection units 35' on the electrode plate 13' or transmit an alternating-current power signal to the patient.

[0389] In this embodiment, each group of ADC units 52' is respectively and electrically connected to one end of a plurality of two-way switches 55' in the corresponding group of two-way changeover switches 55' through a plurality of circuit lines (not labeled) in the adapter 20', and is configured to receive the temperature detection signals transmitted by the multi-purpose signal lines 19' of the corresponding electrode plates 13' and convert the temperature detection signals from analog signals into digital signals. Each group of ADC units 52' includes a plurality of detection channels A, B, C, D, and E, and each detection channel A, B, C, D, and E is used to connect to a corresponding one of the multi-purpose signal lines 19' through the corresponding two-way switch 55'. As Figure 18 shown, each group of ADC units 52' includes a total of 5 detection channels A, B, C, D, and E, namely the first detection channel A, the second detection channel B, the third detection channel C, the fourth detection channel D, and the fifth detection channel E.

Each detection channel A, B, C, D, and E is used to receive the temperature detection signals collected by the corresponding temperature detection unit 35' of the electrode unit 33' connected to the corresponding multi-purpose signal line 19'. In addition, each of the detection channels A, B, C, D, and E is connected to a first power supply module 58' for providing a detection voltage to this detection channel A, B, C, D, and E through a corresponding voltage-dividing resistor 53' in the adapter 20', and the first power supply module 58' provides direct current.

[0390] In this embodiment, the first communication unit 56' is configured to acquire digital signals output by multiple groups of ADC units 52' and send the digital signals to the electric field generator 30'. The electric field generator 30' is further configured to control and adjust the voltage of the alternating electric signal provided to the multiple electrode units 33' of the electrode plate 13' according to the received digital signals. Exemplarily, when any one of the multiple received digital signals exceeds a preset threshold, it indicates that the temperature detected by the temperature detection unit 35' corresponding to at least one electrode unit 33' in the electrode plate 13' exceeds the preset threshold temperature (such as 41 °C, 42 °C, etc.). At this time, the voltage of the alternating electric signal output by the electric field generator 30' can be appropriately reduced or stopped to avoid the temperature of the electrode unit 33' of the electrode plate 13' being too high when applying the alternating electric signal, causing low-temperature burns to the patient's skin. The above preset threshold temperature and preset threshold can be determined according to the human safety threshold. The first communication unit 56' is controlled by the first controller 51' and serially transmits the digital signals converted by multiple groups of ADC units 52'. In this embodiment, the preset threshold temperature can be a value within 36 °C - 45 °C.

[0393] The working principle of the tumor electric field treatment system 100' in this embodiment will be described in detail below with reference to Figures 18 to 20 the following.

[0394] It should be noted that the working principle of temperature acquisition of the tumor electric field treatment system 100' is the same as that of the tumor electric field treatment system 100, and will not be elaborated here.

[0395] The working principle of applying alternating electric signals of the tumor electric field treatment system 100' is similar to that of the tumor electric field treatment system 100. The difference is that in this embodiment, different alternating electric signals can be applied to the electrode units 33 of different column groups at the same time, with higher flexibility.

[0396] Specifically, when it is necessary to apply alternating electric signals to the electrode units 33 of a certain electrode plate 13', the first controller 51' of the adapter 20' or the second controller 37' of the electric field generator 30' controls each two-way switch 55 in a group of two-way switches 55 electrically connected to the electrode plate 13' to conduct at the 2 end and disconnect at the 1 end, and controls a group of power supply switches 40' electrically connected to the electrode plate 13' to conduct. At this time, the second controller 37' of the electric field generator 30' controls the AC signal generator 39' to apply different alternating electric signals to the electrode units 33 of each column group of the electrode plate 13' through different alternating power cords 57', and the magnitudes of the voltages or currents of the different alternating electric signals applied are adjustable. That is, a switching unit (not labeled) is configured to switch the dual-purpose signal lines 19 corresponding to at least two column groups to be connected to different alternating power cords 57', so that each electrode unit 33 of each column group is applied with different alternating electric signals based on different alternating power cords 57'.

[0397] It should be noted that in some other embodiments, the first controller 51' of the adapter 20' or the second controller 37' of the electric field generator 30' can also be used to control a group of bidirectional switches 55' electrically connected to a certain electrode plate 13' to apply different alternating electric signals to some electrode units 33' of the electrode plate 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 second terminal of the first bidirectional switch 55-1' among the multiple bidirectional switches 55' of a group of bidirectional switches 55' electrically connected to the electrode plate 13' to be turned on and the first terminal to be turned off, and controls a power supply switch 40' corresponding to the first bidirectional switch 55-1' among a group of power supply switches 40' electrically connected to the electrode plate 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 the first column group of electrode units 33-1', electrode units 33-6', electrode units 33-11', and electrode units 33-16' of the electrode plate 13' through the corresponding alternating power supply line 57', and the magnitude of the voltage or current of the applied alternating electric signal is adjustable. It should be noted that in some other embodiments, different alternating electric signals can also be applied to two column groups, three column groups, or four column groups of electrode units 33 at the same time period, which will not be elaborated here in detail.

[0398] It should be noted that in the embodiments of the present application, the control switches 54' respectively and electrically connected to the multiple ground wires 18' of the electrode plate 13' and the bidirectional switches 55' respectively and electrically connected to the multiple dual-purpose signal lines 19' of the electrode plate 13' are both provided in the adapter 20'. However, in other embodiments, the control switches 54' electrically connected to the ground wires 18' and the bidirectional switches 55' electrically connected to the dual-purpose signal lines 19' can also be provided on the electrode plate 13' or in the electric field generator 30', which will not be elaborated here. In addition, the ADC unit 52' provided in the adapter 20' can also be provided in the electric field generator 30' and directly controlled by the second controller 37'.

[0399] The tumor electrotherapy system 100' of the present application can achieve real-time and comprehensive monitoring of the temperatures of all electrode units 33' on the electrode patch 13' without increasing the weight of the electrode patch 13' or the core of the first cable 15' electrically connected to the electrode patch 13'. Furthermore, it can judge whether the electrode patch 13' is qualified based on the obtained temperature detection signal; or it can judge whether there are faults or abnormalities in the temperature detection unit 35' of the electrode patch 13' based on the obtained temperature detection signal, and judge whether it is necessary to replace the electrode patch 13' based on the number of temperature detection units 35' with faults or abnormalities; or it can identify the type of the electrode patch based on the obtained temperature detection signal when the electrode patch 13' is qualified; or it can judge whether there is an over-temperature situation in the electrode unit 33' of the electrode patch 13' based on the obtained temperature detection signal when the electrode patch 13' is qualified, and then control the alternating current signal applied to the electrode patch 13' or the corresponding column electrode units 33' of the electrode patch 13' to avoid low-temperature burns on the patient's body surface during tumor treatment through the electrode patch 13'. In addition, the substrate 31' of the electrode patch 13' of the present application electrically connects the same electrode unit 33' and the signal terminal 35-2' of the corresponding temperature detection unit 35' through the same dual-purpose signal line 19' arranged thereon. While it can transmit both the alternating current signal and the direct current signal for temperature signal acquisition and the acquired temperature detection signal through the dual-purpose signal line 19', it also greatly reduces the number of conductive traces (ground wire 18', dual-purpose signal line 19') arranged thereon, reduces the wiring difficulty of the substrate 31', simplifies the manufacturing process, also reduces the weight of the substrate 31', and reduces the manufacturing cost. The electrode patch 13' of the present application can also be switched between applying an alternating current signal for tumor treatment and transmitting the direct current signal for temperature acquisition and the acquired temperature detection signal through the combined control of a control switch 54' electrically connected to the ground wire 18' arranged thereon and a bidirectional switch 55' electrically connected to the dual-purpose signal line 19'.

[0400] Specifically, when it is necessary to apply an alternating electric signal to the patient through each electrode unit 33' of a certain electrode patch 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 patch 13' and simultaneously controls all the bidirectional switching switches 55' in a group of bidirectional switching switches 55' corresponding to the electrode patch 13' to be switched to their respective 2 ends, so that the 1 ends of these bidirectional switching switches 55' are all disconnected and the 2 ends are all conducting, realizing that each two-way signal line 19' of the electrode patch 13' is electrically connected to the corresponding multiple alternating power lines 57' of the adapter 20' and the electrode patch 13', thereby transmitting the same or different alternating electric signals to each electrode unit 33' of the electrode patch 13'. When the temperature detection signals of the temperature detection units 35' corresponding to all the electrode units 33' of the detected electrode patch 13' are much lower than the preset temperature threshold stored in the electric field generator 30' or the adapter 20', the electric field generator 30' controls the AC signal generator 39 to continue generating an alternating electric signal with an increasing voltage or current amplitude, or a constant voltage or current amplitude through its second controller 37', and then transmits it to the corresponding electrode patch 13' through the corresponding multiple alternating power lines 57' of the adapter 20', so as to continue applying the alternating electric signal to the pair of electrode patches 13'; when the temperature detection signals of the temperature detection units 35' corresponding to all the electrode units 33' of the detected electrode patch 13' are lower than but close to the preset temperature threshold stored in the electric field generator 30' or the adapter 20', the electric field generator 30' can reduce the voltage or current of the alternating electric signal generated by the AC signal generator 39' through the second controller 37', and then reduce the voltage or current of the alternating electric signal applied to the pair of electrode patches 13'; when it is detected that the temperature detection signal of the temperature detection unit 35' corresponding to an electrode unit 33' of a certain electrode patch 13' is greater than the preset temperature threshold, the electric field generator 30' controls a group of power supply switches 40' electrically connected to the electrode patch 13' to be disconnected to stop applying the alternating electric signal to the electrode patch 13'; or the second controller 37' of the electric field generator 30' or the first controller 21' of the adapter 20' controls all the bidirectional switching switches 55' in a group of bidirectional switching switches 55' electrically connected to the electrode patch 13' to be switched from their 2 ends to their 1 ends, that is, controls the 1 ends of all the bidirectional switching of the group of bidirectional switching switches 55' electrically connected to the electrode patch 13' to be all conducting and the 2 ends to be all disconnected, thereby realizing stopping applying the alternating electric signal to the electrode patch 13';Or, when it is detected that a temperature detection signal of a 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 a group of power switches 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 21' 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 2 ends to its 1 end, and the second controller 37' of the electric field generator 30' or the first controller 21' of the adapter 20' simultaneously controls the electrode sheet 13' whose temperature detection signal does not exceed the preset temperature threshold and is in a different column from the electrode unit 33' whose temperature detection signal exceeds the preset temperature threshold The remaining two-way switches 55' electrically connected to the unit 33' continue to maintain electrical connection with their respective two ends, so as to stop applying alternating electric signals to all electrode units 33' in the column where the electrode unit 33' whose temperature detection signal of the electrode sheet 13' exceeds the preset temperature threshold, and continue to apply alternating electric signals to the remaining column electrode units 33' whose temperature detection signals of the electrode sheet 13' do not exceed the preset temperature threshold, and the alternating electric signals applied to the remaining column electrode units 33' can be the same or different, for example, the alternating electric signals are continued to be applied in a manner of reducing the voltage or current amplitude of the alternating electric signals for the columns whose temperature detection signals do not exceed the preset temperature threshold but are closer to the preset temperature threshold, and the alternating electric signals are continued to be applied in a manner of increasing the voltage or current amplitude of the alternating electric signals for the columns whose temperature detection signals do not exceed the preset temperature threshold but are farther away from the preset temperature threshold. In this way, the alternating electric signal application control method based on the temperature detection signal of the tumor electric field treatment system 100' is realized. ;

[0401] It should be noted that the alternating electric signal application method, electrode sheet temperature detection method, electrode sheet temperature abnormality detection method, control method, and electrode sheet type identification method of the tumor electric field treatment system 100' of this embodiment are similar to the control method of the aforementioned tumor electric field treatment system 100, with the difference that: the tumor electric field treatment system 100' of this embodiment can also apply different alternating electric signals, such as different voltages or currents, to the electrode units 33' in each area (i.e., each column group) at the same time according to the temperature of the electrode units 33' in each area to prevent the electrode units 33' in the corresponding area from exceeding the preset temperature threshold, so as to apply the electric field continuously for a long time and improve the treatment effect.

[0402] Specifically, the tumor electric field treatment system 100' of this embodiment can be used Figure 8 The electrode sheet temperature detection method shown in the figure determines the temperature of each electrode unit 33' in the electrode sheet 13'. Figure 8 , I will not go into details here.

[0403] The tumor electric field treatment system 100 of this embodiment can be usedFigure 9 The electrode sheet temperature abnormality detection method shown determines whether the electrode sheet 13' is abnormal. For details, refer to Figure 9 , which will not be elaborated here.

[0404] The tumor electric field treatment system 100' of this embodiment can adopt Figure 21 the control method of the tumor electric field treatment system shown to control the intensity of the alternating electric signal applied to the electrode unit 33'. The specific steps are as follows:

[0405] Step 210': Control the switching unit to connect at least one column group corresponding dual-purpose signal line 19' in the corresponding electrode sheet 13' to the corresponding temperature sampling point.

[0406] Step 220': Control the control switch 54' corresponding to each row group to sample the analog temperature signal of the corresponding electrode unit 33' based on the corresponding temperature sampling point, so as to determine the temperature detection signal of each electrode unit 33' in each electrode sheet 13'.

[0407] Step 240': Control the intensity of the alternating electric signal applied to the electrode unit 33' according to the temperature detection signal.

[0408] Specifically, when it is determined that the electrode sheet 13' does not need to be replaced, control or adjust the alternating electric signal applied to each electrode unit 33' in the electrode sheet 13' according to the temperature detection signal detected by the temperature detection unit 35' corresponding to each electrode unit 33' in the obtained electrode sheet 13'.

[0409] In some embodiments, the control of the intensity of the alternating electric signal applied to the electrode unit 33' according to the temperature detection signal in step 240' specifically includes the following steps:

[0410] Step 241': Compare the temperature at each electrode unit 33' in the electrode sheet 13' with a preset temperature threshold according to the temperature detection signal.

[0411] Step 242': Control the intensity of the alternating electric signal according to the comparison result.

[0412] In some embodiments, the control of the intensity of the alternating electric signal according to the comparison result in step 242' specifically includes:

[0413] Step 2421': When the temperature at at least one electrode unit 33' exceeds a preset temperature threshold, stop applying an alternating electric signal to the electrode unit 33' of the electrode sheet 13'. Specifically, when there is a temperature detection signal exceeding the preset temperature threshold among the temperature detection signals of all electrode units 33' of the obtained electrode sheet 13', stop applying the alternating electric signal to the electrode unit 33' of the electrode sheet 13'. When the temperature detection signals of each electrode unit 33' in the obtained electrode sheet 13' do not exceed the preset temperature threshold, continue to apply the alternating electric signal to each electrode unit 33' of the electrode sheet 13'.

[0414] 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 column group where the electrode unit 33' exceeding the preset temperature threshold in the electrode sheet 13' is located.

[0415] Furthermore, when stopping applying the alternating electric signal to all electrode units 33' in the column group where the electrode unit 33' exceeding the preset temperature threshold in the electrode sheet 13' is located, continue to apply the alternating electric signal to the electrode units 33' in other column groups of the electrode sheet 13'. Among them, the intensity of the alternating electric signal applied to the electrode units 33' in other column groups of the electrode sheet 13' is adjustable respectively. For example, all electrode units 33' whose temperature detection signals in the electrode sheet 13' do not exceed the preset temperature threshold and are in different columns from the electrode units 33' whose temperature detection signals exceed the preset temperature threshold will continue to be applied with the alternating electric signal, and the alternating electric signals applied to different column groups can be the same or different. For example, the smaller the amplitude of the voltage or current of the alternating electric signal applied to the column group closer to but not exceeding the preset temperature threshold, and vice versa.

[0416] In some other embodiments, controlling the intensity of the alternating electric signal according to the comparison result in step 242' specifically includes:

[0417] Step 2422': When the temperature at all electrode units 33' in the electrode sheet 13' does not exceed the preset temperature threshold, if the temperature at all electrode units 33' in the electrode sheet 13' does not exceed the first preset temperature, increase the intensity of the alternating electric signal applied to the electrode unit 33' of the electrode sheet 13', where the first preset temperature is less than the preset temperature threshold.

[0418] In step 2422', the increase amplitude of the electric field intensity corresponding to each column group where the intensity of the alternating electric signal is increased can be the same or different, that is, adjustable respectively. For example, the larger the amplitude of the voltage or current of the alternating electric signal applied to the column group with the lower highest temperature, and vice versa.

[0419] Step 2423': When the temperatures at all electrode units 33' in the electrode sheet 13' do not exceed the preset temperature threshold, if there is at least one electrode unit 33' in the electrode sheet 13' where the temperature exceeds the first preset temperature and is less than the preset temperature threshold, keep the intensity of the alternating current signal currently applied to the electrode unit 33' of the electrode sheet 13' unchanged.

[0420] In step 2423', keeping the intensity of the alternating current signal currently applied to the electrode unit 33' unchanged specifically includes: keeping the intensity of the alternating current signal currently applied to the first target column group unchanged, where the first target column group is the column group where there is an electrode unit 33' with a temperature exceeding the first preset temperature and less than the preset temperature threshold. That is to say, it is possible to only keep the amplitude of the voltage or current of the alternating current signal corresponding to the column group with a temperature exceeding the first preset temperature and less than the preset temperature threshold, and the amplitude of the voltage or current of the alternating current signal corresponding to the remaining column groups can still be adjusted according to the temperature of the corresponding column groups.

[0421] Step 2424': When the temperatures at all electrode units 33' in the electrode sheet 13' do not exceed the preset temperature threshold, if there is at least one electrode unit 33' in the electrode sheet 13' where the temperature exceeds the second preset temperature and is less than the preset temperature threshold, reduce the intensity of the alternating current signal applied to the electrode unit 33' of the electrode sheet 13'.

[0422] In step 2424', reducing the intensity of the alternating current signal applied to the electrode unit 33' specifically includes: reducing the intensity of the alternating current signal applied to the electrode unit 33' of the second target column group, where the second target column group is the column group where there is an electrode unit 33' with a temperature exceeding the second preset temperature and less than the preset temperature threshold. That is to say, it is possible to only reduce the amplitude of the voltage or current of the alternating current signal corresponding to the column group with a temperature exceeding the second preset temperature and less than the preset temperature threshold, and the reduced amplitudes can be the same or different, and the amplitude of the voltage or current of the alternating current signal corresponding to the remaining column groups can still be adjusted according to the temperature of the corresponding column groups, such as being kept unchanged or increased.

[0423] Exemplarily, when the temperature detection signal is much lower than the preset temperature threshold, continue to apply an alternating current signal to each electrode unit 33' of the electrode sheet 13' in a manner of increasing the voltage or current amplitude of the alternating current signal applied to each electrode unit 33' of the electrode sheet 13', wherein the amplitudes of the voltage or current of the alternating current signals applied to different column groups may be the same or different, or continue to apply an alternating current signal to each electrode unit 33' of the electrode sheet 13' in a manner of keeping the voltage or current amplitude of the alternating current signal applied to each electrode unit 33' of the electrode sheet 13' unchanged, wherein the amplitudes of the voltage or current of the alternating current signals applied to only some column groups may be kept unchanged. When the temperature detection signal approaches the preset temperature threshold, continue to apply an alternating current signal to each electrode unit 33' of the electrode sheet 13' in a manner of keeping the voltage or current amplitude of the alternating current signal applied to each electrode unit 33' of the electrode sheet 13' unchanged, wherein the amplitudes of the voltage or current of the alternating current signals applied to only some column groups may be kept unchanged, or continue to apply an alternating current signal to each electrode unit 33' of the electrode sheet 13' in a manner of reducing the voltage or current amplitude of the alternating current signal applied to each electrode unit 33' of the electrode sheet 13', wherein the amplitudes of the voltage or current of the alternating current signals applied to different column groups may be the same or different.

[0424] In still some other embodiments, the controlling of the alternating current signal intensity according to the comparison result in step 242' specifically includes:

[0425] Step 2425': When the temperature at at least one electrode unit 33' exceeds the preset temperature threshold, determine the number of over-temperature column groups.

[0426] Step 2426': When the number of over-temperature column groups exceeds the preset number threshold, stop applying the alternating current signal to all electrode units 33' of the electrode sheet 13'.

[0427] Step 2427': When the number of over-temperature column groups does not exceed the preset number threshold, stop applying the alternating current signal to all electrode units 33' of the column group where the electrode units 33' exceeding the preset temperature threshold are located in the electrode sheet 13'.

[0428] Further, in the case of stopping applying an alternating electric signal to all the electrode units 33' in the column group where the electrode units 33' in the electrode sheet 13' exceed the preset temperature threshold, continue to apply an alternating electric signal to the electrode units 33' in other column groups of the electrode sheet 13'. Among them, the intensities of the alternating electric signals applied to the electrode units 33' in other column groups of the electrode sheet 13' are respectively adjustable. For example, all the electrode units 33' in the electrode sheet 13' where the temperature detection signal does not exceed the preset temperature threshold and is in a different column from the electrode units 33' where the temperature detection signal exceeds the preset temperature threshold will continue to be applied with an alternating electric signal, and the alternating electric signals applied to different column groups can be the same or different. For example, the amplitude of the voltage or current of the alternating electric signal applied to the column group closer to but not exceeding the preset temperature threshold is smaller, and vice versa.

[0429] Step 2428': In the case where the number of over-temperature column groups does not exceed the preset number threshold, if the temperature at each electrode unit 33' in the non-over-temperature column groups does not exceed the first preset temperature, increase the intensity of the alternating electric signal applied to the electrode units 33' in the non-over-temperature column groups, where the first preset temperature is less than the preset temperature threshold.

[0430] In step 2428', the increase amplitudes of the electric field intensities corresponding to the column groups where the intensity of the alternating electric signal is increased can be the same or different, that is, respectively adjustable. For example, the larger the amplitude of the voltage or current of the alternating electric signal applied to the column group with the lower highest temperature, and vice versa.

[0431] Step 2429': In the case where the number of over-temperature column groups does not exceed the preset number threshold, if there is at least one electrode unit 33' in the non-over-temperature column groups where the temperature exceeds the first preset temperature and is less than the preset temperature threshold, keep the intensity of the alternating electric signal currently applied to the electrode units 33' in the non-over-temperature column groups unchanged.

[0432] In step 2429', keeping the intensity of the alternating electric signal currently applied to the electrode units 33' unchanged specifically includes: keeping the intensity of the alternating electric signal currently applied to the first target column group unchanged, where the first target column group is the column group where there is an electrode unit 33' with a temperature exceeding the first preset temperature and less than the preset temperature threshold. That is to say, it is possible to only keep the amplitude of the voltage or current of the alternating electric signal corresponding to the column group where the temperature exceeds the first preset temperature and is less than the preset temperature threshold, and the amplitudes of the voltage or current of the alternating electric signals corresponding to the remaining column groups can still be adjusted according to the temperature of the corresponding column groups.

[0433] Step 2430': When the number of over-temperature column groups does not exceed the preset number threshold, if there is at least one electrode unit 33' in the non-over-temperature column groups where the temperature exceeds the second preset temperature and is less than the preset temperature threshold, the intensity of the alternating electric signal applied to the electrode units 33' in the non-over-temperature column groups is reduced, where the second preset temperature is greater than the first preset temperature and less than the preset temperature threshold.

[0434] In step 2430', reducing the intensity of the alternating electric signal applied to the electrode units 33' specifically includes: reducing the intensity of the alternating electric signal applied to the electrode units 33' in the second target column group, where the second target column group is the column group where there is an electrode unit 33' with a temperature exceeding the second preset temperature and less than the preset temperature threshold. That is to say, it is possible to only reduce the amplitude of the voltage or current of the alternating electric signal corresponding to the column group with a temperature exceeding the second preset temperature and less than the preset temperature threshold, and the reduced amplitudes can be the same or different. The amplitudes of the voltage or current of the alternating electric signals corresponding to the remaining column groups can still be adjusted according to the temperature of the corresponding column groups, such as remaining unchanged or increasing.

[0435] Exemplarily, when the temperature detection signal is much lower than the preset temperature threshold, the alternating electric signal is continuously 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', where the amplitudes of the voltage or current of the alternating electric signals applied to different column groups can be the same or different, or the alternating electric signal is continuously applied to each electrode unit 33' of the electrode sheet 13' in a manner of keeping the voltage or current amplitude of the alternating electric signal applied to each electrode unit 33' unchanged, where the amplitudes of the voltage or current of the alternating electric signals applied to only some column groups can be kept unchanged. When the temperature detection signal is close to the preset temperature threshold, the alternating electric signal is continuously applied to each electrode unit 33' of the electrode sheet 13' in a manner of keeping the voltage or current amplitude of the alternating electric signal applied to each electrode unit 33' unchanged, where the amplitudes of the voltage or current of the alternating electric signals applied to only some column groups can be kept unchanged, or the alternating electric signal is continuously 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', where the amplitudes of the voltage or current of the alternating electric signals applied to different column groups can be the same or different.

[0436] The tumor electric field treatment system 100' of this embodiment can adopt Figure 11 the shown electrode sheet type recognition method to recognize the type of the electrode sheet 13', for specific reference Figure 11 and will not be elaborated here.

[0437] The tumor electric field treatment system 100' of this embodiment can adopt Figure 22The signal control method for tumor electrotherapy as shown, combines the control of the control switch 54' and the bidirectional switch 55' electrically connected to the electrode plate 13' to switch each electrode unit 33' of the electrode plate 13' between applying an alternating electric signal and collecting a temperature detection signal.

[0438] Refer to Figure 22 as shown, the method includes:

[0439] Step 310': Combine the control of the control switch 54' and the bidirectional switch 55' electrically connected to the corresponding electrode plate 13' to apply an alternating electric signal to each electrode unit 33' of the electrode plate 13' and execute Step 320';
