Description

TECHNICAL FIELD

[0001] The present application relates to the tumor electric field treatment technology, and in particular to a tumor electric field treatment system, a tumor treatment device and an electrode sheet quality detection method. BACKGROUND

[0002] At present, the tumor electric field treatment system mainly comprises an electric field generator, an adapter electrically connected with the electric field generator, and multiple pairs of electrode sheets electrically connected with the electric field generator through the adapter. The electric field generator transmits an alternating electric signal for tumor electric field treatment to each electrode sheet through the adapter, and then applies an alternating electric field to the tumor site of a patient through the electrode sheet to perform tumor electric field treatment. Since the alternating electric field applied to the patient will gather heat at the corresponding position of the electrode sheet attached to the skin, in order to avoid skin hypothermia burns, a temperature sensor needs to be configured at each electrode unit to monitor the skin surface temperature at each electrode unit. However, during the tumor treatment using the electrode sheet, there will inevitably be an abnormal problem that a small number of temperature sensors on the electrode sheet fail after being used for a period of time. If the number of failed temperature sensors on the electrode sheet is too large, the risk of patient hypothermia burns will be caused. SUMMARY

[0003] The present application aims to at least solve one of the technical problems in the related art. To this end, the first object of the present application is to provide a tumor electric field treatment system, which can control multiple electrode units and sample temperature detection signals using fewer conductive traces, and can realize quality detection of electrode sheets based on the sampled temperature detection signals to monitor whether the electrode sheets are damaged, so as to replace the electrode sheets in time and avoid or reduce the risk of patient hypothermia burns.

[0004] The second object of the present application is to provide a tumor treatment device.

[0005] The third object of the present application is to provide an electrode sheet quality detection method.

[0006] The fourth object of the present application is to provide a computer readable storage medium.

[0007] The fifth object of the present application is to provide an adapter of a tumor electric field treatment system.

[0008] The sixth object of the present application is to provide an electric field generator of a tumor electric field treatment system.

[0009] To achieve the above object, the first aspect of the present application provides a tumor electric field treatment system, comprising: at least one pair of electrode pads, each of the electrode pads comprising a plurality of electrode units and a plurality of temperature detection units, each of the electrode units being capable of applying an alternating electric signal, each of the temperature detection units being arranged corresponding to one of the electrode units, and the signal ends of the temperature detection units being connected to a switching unit through a dual-purpose signal line after being short-circuited with the corresponding electrode units; the switching unit being configured to switch the dual-purpose signal line to be connected to a temperature sampling point or an alternating power supply line, so that, in the case that the dual-purpose signal line is connected to the temperature sampling point, the analog temperature signals detected by the corresponding temperature detection units are sampled based on the temperature sampling point, and the sampled analog temperature signals detected by each of the temperature detection units are used to determine a test code array of the corresponding electrode pad, and the test code array is compared with a standard code array for consistency to detect the quality of the corresponding electrode pad; in the case that the dual-purpose signal line is connected to the alternating power supply line, the corresponding electrode units are applied with the alternating electric signal based on the alternating power supply line.

[0010] According to the tumor electric field treatment system of the present application, for each electrode pad, the signal ends of the temperature detection units corresponding to the electrode units are short-circuited with the corresponding electrode units and are connected to a switching unit through a dual-purpose signal line, and the switching unit is configured to switch the dual-purpose signal line to be connected to a temperature sampling point or an alternating power supply line, so that, in the case that the dual-purpose signal line is connected to the temperature sampling point, the analog temperature signals detected by the corresponding temperature detection units are sampled based on the temperature sampling point, and in the case that the dual-purpose signal line is connected to the alternating power supply line, the corresponding electrode units are applied with the alternating electric signal based on the alternating power supply line. In this way, the sampling of temperature and the application of alternating electric signal can be realized through the dual-purpose signal line, without adding a new alternating signal line (i.e. AC line) and without using the original alternating signal line, so that a smaller number of conductive traces can be used to control a plurality of electrode units, which is conducive to the application of the electrode pad. In addition, the test code array of the electrode pad is determined based on the sampled temperature detection signals, and the test code array is compared with a standard code array for consistency to detect the quality of the corresponding electrode pad, so that whether the electrode pad is damaged can be monitored, and the electrode pad can be replaced in time to avoid or reduce the risk of hypothermia burns of the patient.

DETAILED DESCRIPTION

[0042] The embodiments of the technical scheme of the present application will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical scheme of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0043] First some embodiments:

[0044] Figure 1 The tumor electric field treatment system 100 of the first embodiment of the present application is shown. As shown in the figure, Figure 1 The tumor electric field treatment system 100 includes at least one pair of electrode sheets 110, an adapter 120 connected to the at least one pair of electrode sheets 110, and an electric field generator 130 connected to the adapter 120. The at least one pair of electrode sheets 110 can be arranged in pairs on the surface of the patient, such as Figure 1The four electrode pads 110 in the tumor electric field treatment system 100 are arranged on the surface of the patient's body, and each two electrode pads 110 are arranged as a pair. The electric field generator 130 is used to supply power to at least one pair of electrode pads 110, so that an alternating electric field for treating tumors is generated between the at least one pair of electrode pads 110. The adapter 120 is electrically connected between the at least one pair of electrode pads 110 and the electric field generator 130, and is used to transmit the alternating electric signal generated by the electric field generator 130 to the at least one pair of electrode pads 110. That is, the electric field generator 130 can generate an alternating electric signal, and the alternating electric signal generated by the electric field generator 130 is transmitted to each electrode pad 110 through the adapter 120, so that an alternating electric field for treating tumors is generated between the same pair of electrode pads 110, and an alternating electric field is applied to the tumor site of the patient for tumor treatment.

[0045] As shown in Figure 1 In the present embodiment, the number of electrode pads 110 is four, and each electrode pad 110 includes a plurality of electrode units 112, each of which is electrically connected to the adapter 120, and the number of electrode units 112 on each electrode pad 110 is 20. In other embodiments, the tumor electric field treatment system 100 can also have more or fewer electrode pads 110; in other embodiments, each pair of electrode pads 110 has the same number of electrode units 112, and different pairs of electrode pads 110 can have different numbers of electrode units 112; in other embodiments, the number of electrode units 112 on each electrode pad 110 can be 9, 13, 19, etc.

[0046] Figure 2 As shown in Figure 1 The circuit connection diagram of an electrode pad 110 of the tumor electric field treatment system 100 and the adapter 120 is shown. It is worth noting that: Figure 2 The arrangement of the electrode units 112 shown is to more clearly show the electrical connection between an electrode pad 110 and the adapter 120, Figure 2 The arrangement of the electrode units 112 shown does not represent the spatial arrangement of the electrode units 112. In combination with Figure 1 and Figure 2The electrode sheet 110 comprises a substrate 111, a plurality of electrode units 112 spacedly and electrically connected to the substrate 111, a plurality of temperature detecting units 113, and a first cable 116 electrically connected to the substrate 111. The substrate 111 can be a flexible circuit board. The substrate 111 is embedded with a plurality of conductive tracks, including a plurality of ground lines 118 and a plurality of dual-purpose signal lines 119. The first cable 116 has nine core wires (not shown), each of which is electrically connected to one of the plurality of ground lines 118 and one of the plurality of dual-purpose signal lines 119 of the substrate 111. In the embodiment, the total number of the ground lines 118 and the dual-purpose signal lines 119 embedded in the substrate 111 is no more than 9, and thus the number of the core wires of the first cable 116 is no more than 9.

[0047] The plurality of electrode units 112 are configured as a plurality of row groups and a plurality of column groups. In the embodiment, there are 20 electrode units 112 on each electrode sheet 110, which are grouped according to the circuit connection in the order of 1-20 and divided into four row groups and five column groups, i.e., the 20 electrode units 112 are arranged in four row groups and five column groups in circuit connection. Each electrode unit 112 corresponds to one temperature detecting unit 113, and each temperature detecting unit 113 has a signal end 113B and a ground end 113A. The electrode units 112 and the temperature detecting units 113 are all welded on the substrate 111, and the electrode units 112 are short-circuited with the signal ends 113B of the corresponding temperature detecting units 113. Since the plurality of temperature detecting units 113 are one-to-one corresponding to the plurality of electrode units 112, the plurality of temperature detecting units 113 are also arranged in four row groups and five column groups in circuit connection. It should be noted that the arrangement mode herein is to more clearly show the electrical connection between the electrode sheet 110 and the adapter 120, and does not represent the spatial structure of the electrode units 112. The spatial structure of the electrode units 112 can be, for example, Figure 1The roughly arrayed structure shown can also be other structures, such as petal-shaped or scattered, and can be regular or irregular structures. The electrode units 112 are configured to apply an alternating signal to the tumor site of the patient. The temperature detection units 113 are configured to detect the temperature of the patient's body surface attached to the electrode sheet 110, that is, the temperature at the corresponding electrode unit 112, and output a temperature detection signal to an external device such as the adapter 120. In this embodiment, the multiplexed two-way signal lines 119 of the substrate 111 are respectively arranged in one-to-one correspondence with the plurality of column groups of the electrode units 112, and are configured to transmit the alternating electric signal generated by the electric field generator 130 to each electrode unit 112 in the corresponding column group. That is, the electrode units 112 located in the same column group are all short-circuited through the same two-way signal line 119 of the substrate 111, and the electrode units 112 located in different column groups are respectively connected in parallel through different two-way signal lines 119 of the substrate 111. The two-way signal lines 119 of the substrate 111 are electrically connected to the first cable 116, and are electrically connected to the electric field generator 130 through the adapter 120. Further, the two-way signal lines 119 of the substrate 111 receive the alternating electric signal generated by the electric field generator 130 through the first cable 116 and the adapter 120.

[0048] The multiplexed ground lines 118 are respectively arranged in one-to-one correspondence with the plurality of row groups of the electrode units 112, and the multiplexed ground lines 118 are respectively used to short-circuit each temperature detection unit 113 in each row group to ground in turn. That is, the ground terminals 113A of the plurality of temperature detection units 113 located in the same row group are all short-circuited through the same ground line 118 of the substrate 111, and the ground terminals 113A of the temperature detection units 113 located in different row groups are respectively connected in parallel through different ground lines 118 of the substrate 111. During the period of temperature detection, only one of the multiplexed ground lines 118 is conductive at the same time, and the rest are all disconnected.

[0049] Each of the multiplexed dual-purpose signal lines 119 is also configured to short-circuit the signal terminal 113B of at most one temperature detection unit 113 in each row group to an external device for receiving the detection signal, wherein the signal terminals 113B of the temperature detection units 113 connected by each of the multiplexed dual-purpose signal lines 119 are different from each other to avoid subsequent output of repeated signals by the dual-purpose signal lines 119. That is, when the number of electrode units 112 in a certain row group is the same as the number of the multiplexed dual-purpose signal lines 119, each of the multiplexed dual-purpose signal lines 119 is electrically connected to the signal terminal 113B of a different temperature detection unit 113 in the row group, respectively; when the number of electrode units 112 in a certain row group is less than the number of the multiplexed dual-purpose signal lines 119, at least one of the multiplexed dual-purpose signal lines 119 is not electrically connected to the signal terminal 113B of a temperature detection unit 113, and the remaining multiplexed dual-purpose signal lines 119 are electrically connected to the signal terminals 113B of different temperature detection units 113 in the row group, respectively. In the present embodiment, the external device for receiving the detection signal is the adapter 120. The signal terminals 113B of the plurality of temperature detection units 113 located in different column groups are connected in parallel through different multiplexed dual-purpose signal lines 119 of the substrate 111, respectively, and the signal terminals 113B of the plurality of temperature detection units 113 located in the same column group are all short-circuited to the same multiplexed dual-purpose signal line 119 of the substrate 111.

[0050] In the present embodiment, in the case that each electrode unit 112 is configured with a temperature detection unit 113 for temperature detection, the above-mentioned line design is used to reduce the number of conductive lines of the first cable 116, avoid thickening of the cable, hardening of the softness of the cable, and increase the difficulty of cable fixation; at the same time, the increase in the number of conductive lines of the first cable 116 does not affect the adhesion effect between the electrode sheet 110 and the corresponding body surface of the tumor site of the patient. The embedded ground lines 118 and the multiplexed dual-purpose signal lines 119 in the substrate 111 are a total of 9 lines. Specifically, in the present embodiment, the embedded ground lines 118 in the substrate 111 are 4 lines, and the multiplexed dual-purpose signal lines 119 are 5 lines. The number of ground lines 118 is related to the number of row groups M of electrode units 112, which is greater than or equal to the number of row groups of electrode units 112, and M is a positive integer. The number of multiplexed dual-purpose signal lines 119 is related to the number of column groups N of electrode units 112, which is greater than or equal to the number of column groups of electrode units 112, and N is a positive integer. The number of lines L embedded in the substrate 111 of the electrode sheet 110 is equal to the sum of the number of ground lines 118 and the number of multiplexed dual-purpose signal lines 119. In the present embodiment, the number of ground lines 118 is equal to the number of row groups M of electrode units 112; the number of multiplexed dual-purpose signal lines 119 is equal to the number of column groups N of electrode units 112.

[0051] In terms of spatial structure, the plurality of electrode units 112 are arranged in a two-dimensional array on the substrate 111. As shown in FIG. 1, the plurality of electrode units 112 are arranged in a two-dimensional array on the substrate 111. Figure 1As shown, the electrode sheet 110 in this embodiment includes 20 electrode units 112 and 20 temperature detection units 113 corresponding to the electrode units 112, and the 20 electrode units 112 are arranged in an array of four rows and six columns, with four electrode units 112 in each of the first and fourth rows and six electrode units 112 in each of the second and third rows, and the four electrode units 112 in each of the first and fourth rows are respectively located in each of the second to fifth columns, and the six electrode units 112 in each of the second and third rows are respectively located in each of the first to sixth columns.

[0052] As Figure 1As shown, in the spatial structure, the plurality of electrode units 112 are connected in an asymmetric connection manner, for example, the two adjacent electrode units 112 among the four electrode units 112 located at the third column of the first row, the third column of the second row, the third column of the third row and the third column of the fourth row are all connected through a column connection band (not labeled), and the two adjacent electrode units 112 among the four electrode units 112 located at the fifth column of the first row, the fifth column of the second row, the fifth column of the third row and the fifth column of the fourth row are also all connected through a column connection band (not labeled). Each electrode sheet 110 has a free end, for example, at least one electrode unit 112 among the plurality of electrode units 112 is connected with at most one other electrode unit 112, for example, the electrode units 112 located at the second column of the first row, the first column of the second row, the second column of the second row, the first column of the third row, the second column of the third row and the second column of the fourth row are all not connected with the column connection band in the column direction, so as to form an open space, and the open space is adjustable, for example, the position of the electrode unit 112 at the second column of the first row is movable compared with the position of the electrode unit 112 at the third column of the first row, the position of the electrode unit 112 at the first column of the second row is movable compared with the position of the electrode unit 112 at the second column of the second row, the position of the electrode unit 112 at the first column of the third row is movable compared with the position of the electrode unit 112 at the second column of the third row, and the position of the electrode unit 112 at the second column of the fourth row is movable compared with the position of the electrode unit 112 at the third column of the fourth row, so that when the electrode sheet 110 is attached to the body surface of the patient, by adjusting the positions of the electrode units 112 at the second column of the first row, the first column of the second row, the first column of the third row and the second column of the fourth row, the open space between the corresponding electrode units 112 can be adjusted, so that the heat dissipation space of the corresponding electrode units 112 can be increased, so that the heat dissipation can be accelerated, and at the same time, it is beneficial for the patient to adjust the positions of the electrode units 112 based on the heating condition or the skin condition of the attachment area of the electrode sheet 110.Similarly, the electrode units 112 in the fourth column of the first row, the fourth column of the second row, the sixth column of the second row, the sixth column of the third row and the fourth column of the fourth row are not connected by the connection bands in the column direction, so that open spaces are formed, and the open spaces are adjustable, for example, the position of the electrode unit 112 in the fourth column of the first row is movable compared with the position of the electrode unit 112 in the fifth column of the first row, the position of the electrode units 112 in the fourth column of the second row and the sixth column of the second row is movable compared with the position of the electrode units 112 in the fifth column of the second row, the position of the electrode unit 112 in the sixth column of the third row is movable compared with the position of the electrode unit 112 in the fifth column of the third row, and the position of the electrode unit 112 in the fourth column of the fourth row is movable compared with the position of the electrode unit 112 in the fifth column of the fourth row, so that when the electrode sheet 110 is attached to the body surface of the patient, by adjusting the positions of the electrode units 112 in the fourth column of the first row, the fourth column of the second row, the sixth column of the second row, the sixth column of the third row and the fourth column of the fourth row, the open spaces between the corresponding electrode units 112 can be adjusted, so that the heat dissipation space of the corresponding electrode units 112 can be increased, so that the heat dissipation can be accelerated, and the patient can adjust the positions of the electrode units 112 based on the heating condition or the skin condition of the attachment area of the electrode sheet 110.

[0053] As shown in FIG. 1, the electrode sheet 110 includes 20 electrode units 112 arranged in four rows and five columns. Figure 1 As shown in FIG. 1, the electrode sheet 110 includes 20 electrode units 112 arranged in four rows and five columns. Figure 2 As shown in FIG. 1, the electrode sheet 110 includes 20 electrode units 112 arranged in four rows and five columns.

[0054] Each electrode unit 112 can apply an alternating electric signal, and the electrode sheet 110 arranged in pairs is used to apply an alternating electric field to the tumor site of the patient. Optionally, the electrode unit 112 is a dielectric element, such as a ceramic sheet, or a polymer dielectric layer composed of a polymer material. Each temperature detection unit 113 is arranged corresponding to an electrode unit 112 to detect the temperature at the corresponding electrode unit 112. Each temperature detection unit 113 can be arranged at any position of the corresponding electrode unit 112. In the embodiment, each electrode unit 112 is provided with a through hole 1121, which is suitable for mounting the temperature detection unit 113. For example, the middle part of each electrode unit 112 is provided with a through hole 1121, and each electrode unit 112 is provided with a corresponding temperature detection unit 113 in the through hole 1121. Each temperature detection unit 113 includes a temperature sensor 114 and a diode 115. The temperature sensor 114 has a signal terminal 114B and a ground terminal 114A. The diode 115 has an anode 115B and a cathode 115A. The anode 115B of the diode 115 is connected to the ground terminal 114A of the temperature sensor 114. The cathode 115A of the diode 115 serves as the ground terminal 113A of the temperature detection unit 113. The signal terminal 114B of the temperature sensor 114 serves as the signal terminal 113B of the temperature detection unit 113. The temperature sensor 114 can be a thermistor or other temperature sensor other than a thermistor. Each temperature sensor 114 is provided with a corresponding diode 115, which is connected in series with the temperature sensor 114 of the corresponding electrode unit 112. The diode 115 can prevent reverse current flow to prevent the detection signal from other electrode units 112 from affecting the temperature sensor 114.

[0055] As Figure 2As shown, the electrode sheet 110 of the present embodiment includes 4 ground lines 118, each of which is used to ground the ground terminals 113A of the temperature detection units 113 of the same row group. The 4 ground lines 118 of the electrode sheet 110 are respectively a first ground line 118-1, a second ground line 118-2, a third ground line 118-3, and a fourth ground line 118-4. In the 4 row groups of the electrode sheet 110, the first row group includes the electrode units 112-1 to 112-5, the second row group includes the electrode units 112-6 to 112-10, the third row group includes the electrode units 112-11 to 112-15, and the fourth row group includes the electrode units 112-16 to 112-20. Specifically, the first ground line 118-1 is used to ground the electrode units 112-1 to 112-5 in the first row group; the second ground line 118-2 is used to ground the electrode units 112-6 to 112-10 in the second row group; the third ground line 118-3 is used to ground the electrode units 112-11 to 112-15 in the third row group; and the fourth ground line 118-4 is used to ground the electrode units 112-16 to 112-20 in the fourth row group. It should be noted that these ground lines 118 are selectively closed or disconnected, which can be achieved by connecting each ground line 118 in series with a control switch 124, i.e., the ground terminals 113A of the temperature detection units 113 corresponding to the electrode units 112 in each row group are connected to the ground pin through a control switch 124, which will be described in detail below. The above-mentioned "grounding the electrode units 112" can refer to grounding the ground terminals 114A of the temperature sensors 114 corresponding to the electrode units 112, or can refer to connecting the diodes 115 in series with the temperature sensors 114 corresponding to the same electrode unit 112 and grounding them together. In short, each ground line 118 shorts and grounds the ground terminals 113A of the temperature detection units 113 corresponding to all the electrode units 112 in each row group.

[0056] As Figure 2As shown, the electrode sheet 110 of the present embodiment also includes five two-way signal lines 119, one end of each of the two-way signal lines 119 is connected to all the electrode units 112 in each column group, and the other end is connected to an adapter 120 for receiving temperature detection signals and transmitting alternating electric signals. That is, for each row group, each of the two-way signal lines 119 can selectively connect one of the electrode units 112 or none of the electrode units 112 in the row group to avoid subsequent output of duplicate signals by the two-way signal lines 119. Specifically, the five two-way signal lines 119 of the electrode sheet 110 include a first two-way signal line 119-1, a second two-way signal line 119-2, a third two-way signal line 119-3, a fourth two-way signal line 119-4, and a fifth two-way signal line 119-5. One end of the first two-way signal line 119-1 is simultaneously connected to the signal end 113B of the temperature detection unit 113 corresponding to each of the four electrode units 112-1, 112-6, 112-11, and 112-16; one end of the second two-way signal line 119-2 is simultaneously connected to the signal end 113B of the temperature detection unit 113 corresponding to each of the four electrode units 112-2, 112-7, 112-12, and 112-17; one end of the third two-way signal line 119-3 is simultaneously connected to the signal end 113B of the temperature detection unit 113 corresponding to each of the four electrode units 112-3, 112-8, 112-13, and 112-18; one end of the fourth two-way signal line 119-4 is simultaneously connected to the signal end 113B of the temperature detection unit 113 corresponding to each of the four electrode units 112-4, 112-9, 112-14, and 112-19; and one end of the fifth two-way signal line 119-5 is connected to the signal end 113B of the temperature detection unit 113 corresponding to each of the four electrode units 112-5, 112-10, 112-15, and 112-20. In short, each of the two-way signal lines 119 parallelly shorts the signal end 113B of each of the electrode units 112 and the temperature detection unit 113 corresponding thereto in the same column group to serve as a temperature sampling point (not labeled) and is connected to an external device. It should be noted that the two-way signal lines 119 can selectively transmit alternating electric signals or receive temperature detection signals, which can be achieved by connecting each of the two-way signal lines 119 in series with a bidirectional switch 125 and cooperating with the closing or opening of the ground line 118.That is, after the signal terminals 113B of the temperature detection units 113 in each column group are respectively short-circuited with the corresponding electrode units 112, the signal terminals 113B are connected to a switching unit (not labeled) through a two-way signal line 119. The switching unit (not labeled) includes a plurality of bidirectional switching switches 125 configured to switch the two-way signal line 119 to be connected to a temperature sampling point (not labeled) or an alternating current power line 127. In the case that the two-way signal line 119 is connected to the temperature sampling point (not labeled), the switching state of the control switch 124 is configured to make the temperature detection signal detected by the corresponding temperature detection unit 113 in each row group be sampled based on the temperature sampling point (not labeled). In the case that the two-way signal line 119 is connected to the alternating current power line 127, the electrode units 112 of at least one column group are applied with an alternating current signal based on the alternating current power line 127. The analog temperature signal detected by each temperature detection unit 113 that is sampled is used to determine a test encoding array of the corresponding electrode sheet 110. The test encoding array is compared with a preset standard encoding array to detect the quality of the electrode sheet 110. For example, in the use of the electrode sheet 110, the failure of each temperature detection unit 113 in the corresponding electrode sheet 110 is identified. Alternatively, in the production of the electrode sheet 110, whether the corresponding electrode sheet 110 is qualified is determined. Details will be described below.

[0057] The multi-path ground lines 118 and the multi-path two-way signal lines 119 are conductive tracks embedded in the substrate 111. The substrate 111 is electrically connected to the first cable 116. The multi-path ground lines 118 and the multi-path two-way signal lines 119 embedded in the substrate 111 are respectively electrically connected to the corresponding conductive lines (not shown) in the first cable 116.

[0058] The tumor electric field treatment system 100 of the embodiment includes at least one pair of the electrode sheet 110, the adapter 120 electrically connected to the electrode sheet 110, and the electric field generator 130 electrically connected to the adapter 120. The adapter 120 is connected between the electrode sheet 110 and the electric field generator 130. The electric field generator 130 provides an alternating current signal to the electrode units 112 of the electrode sheet 110 via the two-way signal line 119 of the adapter 120, or receives the temperature detection signal output by the temperature detection unit 113 corresponding to the electrode unit 112. The adapter 120 transmits the alternating current signal generated by the electric field generator 130 to the two-way signal line 119 of the electrode sheet 110, and is also configured to receive the temperature detection signal output by the multi-path two-way signal line 119 of the electrode sheet 110.

[0059] Reference Figure 2 and Figure 3As shown, the adapter 120 comprises a first controller 121, a plurality of groups of ADC units 122 connected to the first controller 121, a plurality of groups of voltage dividing resistors 123 and a plurality of groups of control switches 124 corresponding to the plurality of groups of ADC units 122, a plurality of groups of bidirectional switches 125 connected to the plurality of groups of ADC units 122, a first communication unit 126, a plurality of groups of alternating power lines 127 corresponding to the plurality of groups of bidirectional switches 125, and a first power module 128 connected to the first communication unit 126, the first controller 121 and the plurality of groups of ADC units 122, which provides direct current power VCC for each electronic component of the adapter 120. The adapter 120 further comprises a plurality of circuit lines (not labeled) respectively connected to the plurality of ground lines 118 and the plurality of dual-purpose signal lines 119 in the substrate 111 of the corresponding electrode sheet 110 through the first cable 116 of the electrode sheet 110. The plurality of circuit lines (not labeled) comprises a plurality of alternating power lines 127 respectively transmitting alternating electric signals to the corresponding electrode sheet 110 and electrically connected to the plurality of dual-purpose signal lines 119 in the substrate 111 of the corresponding electrode sheet 110, a plurality of circuit lines (not labeled) respectively electrically connected to the plurality of dual-purpose signal lines 119 in the substrate 111 of the corresponding electrode sheet 110 and used for supplying power to each temperature detection unit 113 of the electrode sheet 110 or transmitting temperature detection signals of the electrode sheet 110, and a plurality of circuit lines (not labeled) respectively electrically connected to the plurality of ground lines 118 in the substrate 111 of the corresponding electrode sheet 110. The number L of circuit lines electrically connected to the electrode sheet 110 is equal to the sum of the number of rows and the number of columns of the electrode units 112 of the electrode sheet 110; the number H of circuit lines electrically connected to X electrode sheets 110 is equal to X times the number of circuit lines electrically connected to a single electrode sheet 110, i.e. H = XL = X(M+N). The number of groups of control switches 124 and the number of groups of bidirectional switches 125 are related to the number of electrode sheets 110. The number of groups of control switches 124 is the same as the number of groups of bidirectional switches 125, and is not less than the number of electrode sheets 110. Alternatively, the number of groups of control switches 124 and the number of groups of bidirectional switches 125 are the same as the number of electrode sheets 110. The following will be described in detail by taking an example of the electrical connection between an electrode sheet 110 with 20 electrode units 112 and the adapter 120.

[0060] Each group of control switches 124 has multiple control switches 124, which are respectively connected to the adapter 120 and electrically connected to the circuit lines (unlabeled) corresponding one-to-one with the multiple grounding lines 118 of a corresponding electrode piece 110, and are configured to control the conduction or disconnection of the multiple grounding lines 118. The circuit lines (unlabeled) that are each electrically connected to the multiple grounding lines 118 of the electrode piece 110 are grounded to GND at the end closest to the control switch 124. The number of control switches 124 in each group of control switches 124 is related to the number of grounding lines 118 on the substrate 111 of the corresponding electrode piece 110, that is, related to the number of rows of multiple electrode units 112 configured; in this embodiment, both are equal. Figure 2 As shown, in this embodiment, the multiple control switches 124 in each group of control switches 124 are respectively the first control switch 124-1, the second control switch 124-2, the third control switch 124-3, and the fourth control switch 124-4. The multiple control switches 124 in the same group each control the closing or opening of the corresponding grounding wire 118 of the same electrode plate 110. Specifically, the first control switch 124-1 is used to control the opening or closing of the first grounding wire 118-1 of the corresponding electrode plate 110, and can cooperate with the corresponding set of bidirectional switching switches 125 to control the power supply and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 in the first row of the electrode plate 110, from electrode unit 112-1 to electrode unit 112-5. The second control switch 124-2 is used to control the opening or closing of the second grounding wire 118-2 of the electrode plate 110, and can cooperate with the corresponding set of bidirectional switching switches 125 to control the power supply and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 in the second row of the electrode plate 110, from electrode unit 112-6 to electrode unit 112-10. The third control switch 124-3 is used to control the opening or closing of the third grounding wire 118-3 of the electrode plate 110, and can cooperate with the corresponding set of bidirectional switching switches 125 to control the energization and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 (112-11 to 112-15) in the third row of the electrode plate 110; the fourth control switch 124-4 is used to control the opening or closing of the fourth grounding wire 118-4 of the electrode plate 110, and can cooperate with the corresponding set of bidirectional switching switches 125 to control the energization and de-energization of the temperature detection units 113 corresponding to the five electrode units 112 (112-16 to 112-20) in the fourth row of the electrode plate 110. The control switches 124 can be mechanical switches, such as relays. The control switches 124 can also be electronic switches, and each control switch 124 can be opened and closed by an additional first controller 121.

[0061] In the embodiment, each of the plurality of groups of control switches 124 is an electronic switch. The first controller 121 is in communication connection with the plurality of groups of control switches 124, and is configured to sequentially and cyclically control the on-off state of each of the plurality of control switches 124 in each group of control switches 124, so as to sequentially and individually turn on each of the plurality of ground lines 118 of the corresponding electrode sheet 110 and cooperate with the switching of the corresponding bidirectional switch 125, so as to collect the temperature of the patient's body surface detected by all the temperature detection units 113 on the electrode sheet 110. The number of each group of control switches 124 is not less than the number of the ground lines 118 of the corresponding substrate 111 of the electrode sheet 110. In the embodiment, the number of each group of control switches 124 is the same as the number of the ground lines 118 of the corresponding electrode sheet 110.

[0062] Each group of bidirectional switches 125 is provided with a plurality of bidirectional switches 125, and the plurality of bidirectional switches 125 in each group are respectively connected to the circuit lines (not labeled) corresponding to the plurality of dual-purpose signal lines 119 of the corresponding electrode sheet 110 in the adapter 120 and are respectively electrically connected to the circuit lines. The number of bidirectional switches 125 in each group of bidirectional switches 125 is related to the number of dual-purpose signal lines 119 of the corresponding substrate 111 of the electrode sheet 110, which is greater than or equal to the number of dual-purpose signal lines 119 of the corresponding substrate 111 of the electrode sheet 110, and in the embodiment, the two are equal. That is, the number of bidirectional switches 125 in each group of bidirectional switches 125 is related to the number of column groups of the plurality of electrode units 112 of the corresponding electrode sheet 110, which is greater than or equal to the number of column groups of the plurality of electrode units 112 of the corresponding electrode sheet 110, and in the embodiment, the two are equal. Since the number of column groups of the plurality of electrode units 112 of an electrode sheet 110 is related to the number of electrode units 112 of the row group with the most electrode units 112, the number of bidirectional switches 125 in each group of bidirectional switches 125 is also related to the number of electrode units 112 of the row group with the most electrode units 112 of the corresponding electrode sheet 110, and in the embodiment, the two are equal. Each bidirectional switch 125 has two ends labeled 1 and 2. The 1 end of each bidirectional switch 125 in the same group is electrically connected to the corresponding detection channel of the corresponding group of ADC units 122 through a temperature sampling point (not labeled). The 2 end of each bidirectional switch 125 in the same group is electrically connected to the corresponding same alternating power supply line 127, and is configured to control the connection of the plurality of dual-purpose signal lines 119 to the corresponding alternating power supply line 127 to transmit alternating electrical signals or to the corresponding detection channel of the corresponding group of ADC units 122 to receive the temperature detection signal output by the temperature detection unit 113.

[0063] As Figure 2As shown, taking the example of the electrical connection between one electrode sheet 110 and the adapter 120, in the present embodiment with 20 electrode units 112, the multiple bidirectional switches 125 in each group of bidirectional switches 125 are respectively a first bidirectional switch 125-1, a second bidirectional switch 125-2, a third bidirectional switch 125-3, a fourth bidirectional switch 125-4, and a fifth bidirectional switch 125-5. The multiple bidirectional switches 125 in the same group respectively control the switching of a corresponding one of the multiple dual-purpose signal lines 119 of the same electrode sheet 110 between the transmission of the alternating electrical signal and the transmission of the temperature detection signal.

[0079] When the control switch 124-3 is closed, the control switch 124-1, the control switch 124-2 and the control switch 124-4 are all opened, and the first bidirectional switch 125-1, the second bidirectional switch 125-2, the third bidirectional switch 125-3, the fourth bidirectional switch 125-4 and the fifth bidirectional switch 125-5 are all switched to the 1 end, the electrode units 112-11 to 112-15 of the third row group are powered on, the electrode units 112-1 to 112-10 and 112-16 to 112-20 of the other row groups are powered off, the signal end 113B of the temperature detection unit 113 corresponding to each of the short-circuited electrode units 112-1, 112-6, 112-11 and 112-16 on the first detection channel A of the ADC unit 122 is connected, only the ground end 113A of the temperature detection unit 113 corresponding to the electrode unit 112-11 is connected to the ground, the ground end 113A of each of the temperature detection units 113 corresponding to the electrode units 112-1, 112-6 and 112-16 is disconnected, each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, and the resistance value of the temperature detection unit 113 corresponding to the electrode unit 112-11 is not affected, so only the temperature detection unit 113 corresponding to the electrode unit 112-11 works effectively on the first detection channel A of the ADC unit 122, and the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-11. Similarly, the voltage value collected by the second detection channel B of the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-12.

The voltage value collected by the fifth detection channel E of the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-15.

[0080] When the control switch 124-4 is closed, the control switch 124-1, the control switch 124-2 and the control switch 124-3 are all open, and the first bidirectional switch 125-1, the second bidirectional switch 125-2, the third bidirectional switch 125-3, the fourth bidirectional switch 125-4 and the fifth bidirectional switch 125-5 are all switched to the 1 end, the electrode units 112-16 to 112-20 of the fourth row group are powered on, and the electrode units 112-1 to 112-15 of the other row groups are powered off, the signal end 113B of the temperature detection unit 113 corresponding to each of the short-circuited electrode units 112-1, 112-6, 112-11 and 112-16 on the first detection channel A of the ADC unit 122 is connected, only the ground end 113A of the temperature detection unit 113 corresponding to the electrode unit 112-16 is connected to the ground, each temperature detection unit 113 includes a temperature sensor 114 and a diode 115 connected in series with the temperature sensor 114, and the resistance value of the temperature detection unit 113 corresponding to the electrode unit 112-16 is not affected, so only the temperature detection unit 113 corresponding to the electrode unit 112-16 works effectively on the first detection channel A of the ADC unit 122. At this time, the temperature detection signal (voltage value) collected by the first detection channel A is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-16. Similarly, the voltage value collected by the second detection channel B of the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-17. The voltage value collected by the third detection channel C of the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-18. The voltage value collected by the fourth detection channel D of the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-19. The voltage value collected by the fifth detection channel E of the ADC unit 122 is the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-20.

[0081] Thus, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can collect the temperature detection signals of the temperature detection units 113 corresponding to all the electrode units 112 of an electrode sheet 110 by controlling the group of bi-directional switching switches 125 and the group of control switches 124 electrically connected to the electrode sheet 110. That is, the switching unit (not numbered) is configured to switch the two-purpose signal lines 119 corresponding to at least two column groups to be connected to the corresponding temperature sampling points (not numbered) at the same time, and the temperature detection signals detected by the corresponding temperature detection units 113 in each row group are sampled based on the corresponding temperature sampling points (not numbered) by configuring the switching state of the corresponding control switches 124. Similarly, the temperature detection signals of the temperature detection units 113 of the electrode units 112 of the other electrode sheets 110 can be obtained.

[0082] The first controller 121 or the second controller 131, the groups of ADC units 122, and the groups of bi-directional switching switches 125 can automatically perform operations through pre-programmed program codes. For example, the first controller 121 or the second controller 131 first controls all the bi-directional switching switches 125 in the corresponding group of bi-directional switching switches 125 to switch to the 1 end so that the 1 end of the bi-directional switching switches 125 is all turned on and the 2 end is all turned off, so that the two-purpose signal lines 119 of the corresponding electrode sheet 110 are electrically connected to the corresponding group of ADC units 122. Then, the control switch 124-1 in the corresponding group of control switches 124 is closed, and the remaining control switches 124-2 to 124-4 in the group of control switches 124 are opened. During this period, the detection channels A, B, C, D, and E of the group of ADC units 122 acquire the temperature detection signals of the temperature detection units 113 corresponding to the electrode units 112 in the first row group in the corresponding electrode sheet 110, convert them into digital signals, and store them in the additionally provided memory. Then, after a preset interval, the first controller 121 or the second controller 131 closes the control switch 124-2 in the group of control switches 124, and opens the control switch 124-1, the control switch 124-3, and the control switch 124-4 in the group of control switches 124. During this period, the detection channels A, B, C, D, and E of the group of ADC units 122 acquire the temperature detection signals of the temperature detection units 113 corresponding to the electrode units 112 in the second row group. In this way, by sequentially turning on each control switch 124 in the group of control switches 124, the temperature detection signals of all the temperature detection units 113 on the electrode sheet 110 can be obtained. Similarly, the temperature detection signals of all the temperature detection units 113 on at least one pair of electrode sheets 110 can be obtained through such operations.

[0083] It should be noted that in other embodiments, the temperature detection signals of the temperature detection units 113 corresponding to the electrode units 112 of a column group can also be sampled in the same temperature sampling period by controlling the group of bidirectional switches 125 and the group of control switches 124 electrically connected to the electrode sheet 110 through the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130. For example, when only the first bidirectional switch 125-1 is switched to its 1 terminal, the control switch 124-1 can be first controlled to be closed, and the control switch 124-2, the control switch 124-3 and the control switch 124-4 are all opened, at this time only the temperature detection units 113 corresponding to the electrode units 112-1 of the first row group are powered on, the signal end 113B of the temperature detection unit 113 corresponding to the electrode unit 112-1 is short-circuited on the first detection channel A of the group of ADC units 122, and therefore the group of ADC units 122 will detect the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-1; then the control switch 124-2 is closed, and the control switch 124-1, the control switch 124-3 and the control switch 124-4 are all opened, at this time the group of ADC units 122 will detect the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-6; then the control switch 124-3 is closed, and the control switch 124-1, the control switch 124-2 and the control switch 124-4 are all opened, at this time the group of ADC units 122 will detect the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-11; finally the control switch 124-4 is closed, and the control switch 124-1, the control switch 124-2 and the control switch 124-3 are all opened, at this time the group of ADC units 122 will detect the voltage value of the temperature detection unit 113 corresponding to the electrode unit 112-16. Thus, in the same sampling period, only the temperature detection signals of the temperature detection units 113 corresponding to the electrode units 112 of a column group can be sampled. Similarly, in other sampling periods, the temperature detection signals of the temperature detection units 113 corresponding to the electrode units 112 of other column groups can be sampled. That is, the switching unit (not numbered) is configured to switch the dual-purpose signal lines 119 corresponding to each column group to be connected to the corresponding temperature sampling points (not numbered) respectively, and the temperature detection signals detected by each temperature detection unit 113 in each column group are sampled by configuring the switch state of the control switch 124. It should be noted that in other embodiments, the temperature detection signals of the temperature detection units 113 corresponding to two column groups, three column groups or four column groups of electrode units 112 can also be sampled in the same sampling period, which will not be described in detail here.

[0084] Specifically, when it is required to apply an alternating electric signal to each electrode unit 112 of a certain electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls the 2 terminal of each of the plurality of bidirectional switching switches 125 of the group of bidirectional switching switches 125 electrically connected to the electrode sheet 110 to be conductive and the 1 terminal to be disconnected, controls all of the plurality of control switches 124 of the group of control switches 124 electrically connected to the electrode sheet 110 to be disconnected, and controls one of the power supply switches 133 electrically connected to the electrode sheet 110 to be conductive, at this time, the second controller 131 of the electric field generator 130 controls the alternating current signal generator 132 to apply an alternating electric signal to each electrode unit 112 of the electrode sheet 110 through the alternating power supply line 127, and the voltage or current of the applied alternating electric signal is adjustable. That is, the switching unit (not numbered) is configured to switch the two-purpose signal line 119 corresponding to at least two column groups to be connected to the alternating power supply line 127 at the same time, so that the electrode units 112 of the at least two column groups are simultaneously applied with the alternating electric signal based on the alternating power supply line 127.

[0085] It should be noted that in other embodiments, a group of bidirectional switching switches 125 electrically connected to a certain electrode sheet 110 can also be controlled by the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 to apply an alternating electric signal to part of the electrode units 112 of the electrode sheet 110 during the same time period. For example, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 controls the 2 terminal of the first bidirectional switching switch 125-1 of the plurality of bidirectional switching switches 125 of the group of bidirectional switching switches 125 electrically connected to the electrode sheet 110 to be conductive and the 1 terminal to be disconnected, controls all of the plurality of control switches 124 of the group of control switches 124 electrically connected to the electrode sheet 110 to be disconnected, and controls one of the power supply switches 133 electrically connected to the electrode sheet 110 to be conductive, at this time, the second controller 131 of the electric field generator 130 controls the alternating current signal generator 132 to apply an alternating electric signal to the first column group electrode unit 112-1, the electrode unit 112-6, the electrode unit 112-11, and the electrode unit 112-16 of the electrode sheet 110 through the alternating power supply line 127, and the voltage or current of the applied alternating electric signal is adjustable. That is, the switching unit (not numbered) is configured to switch the two-purpose signal line 119 corresponding to each column group to be connected to the alternating power supply line 127, respectively, so that the electrode units 112 of each column group are simultaneously applied with the alternating electric signal based on the alternating power supply line 127. It should be noted that in other embodiments, two column groups, three column groups, or four column groups of electrode units 112 can also be simultaneously applied with an alternating electric signal during the same time period, which will not be described in detail here.

[0086] Specifically, during the use of the electrode pad 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can determine the test code array of the electrode pad 110 based on the temperature detection signal detected by each sampled temperature detection unit 113, and compare the test code array with the standard code array to monitor whether the electrode pad 110 is damaged, so as to replace the electrode pad 110 in time and avoid or reduce the risk of low-temperature burns to the patient. For example, the temperature sensor 114 in the temperature detection unit 113 is a negative temperature coefficient thermistor, which has the characteristic that the higher the temperature, the lower the resistance, and the lower the temperature, the higher the resistance. Since the electrode pad 110 is applied to the human body surface during use, and the human body surface temperature is generally between 36℃ and 37℃, a negative temperature coefficient thermistor with a temperature range of 0℃ to 50℃ can be selected. For example, you can choose a thermistor with model number NCP18XH103D03RB. When the temperature it senses is 0℃, the corresponding resistance is approximately 27.45KΩ; when the temperature it senses is 25℃, the corresponding resistance is approximately 10.0KΩ; and when the temperature it senses is 50℃, the corresponding resistance is approximately 4.16KΩ.

[0087] like Figure 5 As shown, when any control switch 124 is turned on, the DC power supply VCC provides DC power to the voltage divider resistor 123, the temperature sensor 114, and the diode 115 in sequence. The ADC unit 122 in the adapter 120 collects the voltage between the temperature sensor 114 and the voltage divider resistor 123 through the corresponding acquisition channel, that is, the voltage division between the temperature sensor 114, the diode 115, and the voltage divider resistor 123, and obtains the AD sampling value, that is, the voltage value (the voltage value of the thermistor), as shown in the following formula (1):

[0088] VADC=(VCC-VD)×R / (Rz+R) (1)

[0089] Where VADC is the AD sampling value, i.e., the voltage value, VCC is also used to represent the voltage of the DC power supply, VD is the voltage drop of diode 115, R is the resistance of the thermistor, and Rz is the resistance of voltage divider resistor 123.

[0090] Assuming that the voltage drop VD of the diode 115 is 0.3V, and the resistance Rz of the voltage dividing resistor 123 is 10KΩ, when the temperature sensor 114 senses a temperature of 0℃, the corresponding resistance is about 27.45KΩ, and based on the formula (1), the corresponding AD sampling value V0=(3.3-0.3)×27.45 / (10+27.45)=2.20V can be obtained; when the temperature sensor 114 senses a temperature of 25℃, the corresponding resistance is about 10.0KΩ, and based on the formula (1), the corresponding AD sampling value V25=(3.3-0.3)×10 / (10+10)=1.50V can be obtained; when the temperature sensor 114 senses a temperature of 50℃, the corresponding resistance is about 4.16KΩ, and based on the formula (1), the corresponding AD sampling value V50=(3.3-0.3)×4.16 / (10+4.16)=0.88V can be obtained. When the temperature sensor 114 is disconnected, for example, the temperature sensor 114 is abnormally welded or the temperature sensor 114 is open, the corresponding AD sampling value is 3.3V. When the temperature sensor 114 and the diode 115 are short-circuited, the corresponding AD sampling value is 0V.

[0091] Since the ADC unit 122 collects the voltage value of the temperature sensor 114, the temperature sensor 114 detects different temperatures, and each temperature has a corresponding different voltage value, the voltage value collected by the ADC unit 122 can be reasonably segmented for differentiation, and the voltage value can be converted into a corresponding code, i.e., different voltage intervals of the voltage value correspond to different codes, and based on the code, the test code array of the electrode sheet 110 can be determined. The test code array includes at least one of a first code, a second code, and a third code, wherein the first code is used to indicate that the temperature detection unit 113 is in a normal state, the second code is used to indicate that the temperature detection unit 113 is in a disconnected state or an unset state, and the third code is used to indicate that the temperature detection unit 113 is in a short-circuit state.

[0092] Specifically, taking the temperature sensor 114 sensing a temperature in the range of 0℃-50℃ and the AD sampling value, i.e., the voltage value, obtained by the ADC unit 122 being in the range of 0.88V-2.20V as an example, considering the detection error factors, etc., the range of the voltage value can be appropriately enlarged to 0.5V-3V.

[0093] When the AD sampling value obtained by the ADC unit 122 is greater than 0.5V and less than 3V, the corresponding code is the first code, such as 1; when the AD sampling value obtained by the ADC unit 122 is less than or equal to 0.3V, the corresponding code is the third code, such as 0; when the AD sampling value obtained by the ADC unit 122 is greater than or equal to 3.1V, the corresponding code is the second code, such as 2. Therefore, in the corresponding detection positions of the electrode sheet 110 numbered 1-20, if the temperature sensor 114 is short-circuited, the corresponding code is 0, i.e., the third code; if the temperature sensor 114 is present, the corresponding code is 1, i.e., the first code; and if the temperature sensor 114 is absent or disconnected, the corresponding code is 2, i.e., the second code.

[0094] Reference Figure 2 As shown, under normal circumstances, when the electrode sheet 110 has 20 electrode units 112, each of which corresponds to a temperature sensor 114 and a diode 115, i.e., the corresponding detection positions of the electrode sheet 110 numbered 1-20 all have temperature sensors 114, and the codes are all 1, the 20 codes are combined to obtain a standard code array 1111111111 11111 11111 of 20 bits. When the temperature sensor 114 is disconnected, assuming that the temperature sensor 114 in the detection position numbered 1 is disconnected, the 20-bit test code array obtained is 21111 11111 11111 11111. When the temperature sensor 114 is short-circuited, assuming that the temperature sensor 114 in the detection position numbered 1 is short-circuited, the 20-bit code array obtained is 01111 11111 11111 11111. Similarly, under normal circumstances, Figure 6 As shown, the standard code array of the electrode sheet 210 is 1111 1111 1111 1111 1111.

[0095] Reference Figure 10 As shown, under normal circumstances, when the electrode sheet 410 has 13 electrode units 412, each of which corresponds to a temperature sensor 414 and a diode 415, i.e., the corresponding detection positions of the electrode sheet 410 numbered 1-13 all have temperature sensors 414, and the codes are all 1, the 13 codes are combined to obtain a standard code array 11111 11111 111 of 13 bits. When the temperature sensor 414 is disconnected, assuming that the temperature sensor 414 in the detection position numbered 1 is disconnected, the 13-bit test code array obtained is 21111 11111 111. When the temperature sensor 414 is short-circuited, assuming that the temperature sensor 414 in the detection position numbered 1 is short-circuited, the 13-bit code array obtained is 0111111111 111. Similarly, under normal circumstances, Figure 12The standard code array of the electrode sheet 510 is 1111 1111 1111 1. Figure 13 The standard code array of the electrode sheet 610 is 1111 1111 1111 1. Figure 15 The standard code array of the electrode sheet 710 is 111 111 111 1111.

[0096] Reference Figure 19 As shown, under normal circumstances, when the electrode sheet 1010 has 9 electrode units 1012, each of which corresponds to a temperature sensor 1014 and a diode 1015, i.e., the electrode sheet 1010 has temperature sensors 1014 at the detection positions numbered 1-9, and the codes are all 1, the 9-bit standard code array 11111 1111 is obtained by combining the 9 codes. When the temperature sensor 1014 is open-circuit, assuming that the temperature sensor 1014 at the detection position numbered 1 is open-circuit, the 9-bit test code array 21111 1111 is obtained. When the temperature sensor 1014 is short-circuit, assuming that the temperature sensor 1014 at the detection position numbered 1 is short-circuit, the 9-bit test code array 011111111 is obtained. Similarly, Figure 21 The standard code array corresponding to the electrode sheet 1110 is 111 111 111.

[0097] Based on the above coding rules, the quality of the electrode sheet 110 can be detected during use, so as to replace the electrode sheet 110 in time and avoid low-temperature scalding. The specific process is as follows:

[0098] Step one: providing at least one pair of qualified electrode sheets 110 (since the electrode sheet 110 is a medical instrument, each electrode sheet 110 will be subjected to various tests before leaving the factory to ensure that the electrode sheet 110 is qualified, so the electrode sheet 110 provided to the user is a qualified electrode sheet 110). Connect at least one pair of qualified electrode sheets 110 to the adapter 120 described above, and connect the adapter 120 to the electric field generator 130 described above.

[0099] Step two: power on the electric field generator 130 to provide a direct current source VCC for the temperature detection unit 113 in at least one pair of qualified electrode sheets 110 to perform temperature detection. The ADC unit 122 in the adapter 120 collects the analog temperature signals detected by the temperature detection unit 113 of at least one pair of qualified electrode sheets 110 to obtain a plurality of AD sample values, and the first controller 121 in the adapter 120 obtains at least two groups of standard code arrays A1, A2 according to the above coding rules. At least two groups of standard code arrays A1, A2 can be stored in the adapter 120 and used as comparison codes.

[0100] Step three: turn off the power of the electric field generator 130, and arrange the aforementioned at least one pair of qualified electrode pieces 110 on the body surface corresponding to the tumor part of the patient.

[0101] Step four: turn on the electric field generator 130, provide direct current power VCC for the temperature detection unit 113 in the at least one pair of qualified electrode pieces 110 to conduct temperature detection, and provide alternating electric signals for the electrode unit 112 in the electrode piece 110 to form an alternating electric field between the paired electrode pieces 110 for tumor electric field treatment. The ADC unit 122 in the adapter 120 collects the temperature signals detected by the temperature detection unit 113 in the at least one pair of qualified electrode pieces 110, obtains a plurality of AD sampling values, and the first controller 121 in the adapter 120 obtains at least two sets of detection encoding arrays B1', B2' according to the aforementioned encoding rules.

[0102] Step five: the first controller 121 in the adapter 120 compares the detection encoding arrays B1', B2' with the corresponding standard encoding arrays A1, A2 respectively, if the detection encoding arrays B1', B2' are consistent with the standard encoding arrays A1, A2, then the steps four and five are cycled; if there is at least one detection encoding array B1' or B2' inconsistent with the standard encoding arrays A1, A2, then step six is performed.

[0103] Step six: the adapter 120 confirms the number of abnormal temperature detection units 113 in the electrode piece 110 corresponding to the inconsistent detection encoding array B1' or / and B2', and judges whether the number of abnormal temperature detection units 113 in the corresponding electrode piece 110 exceeds the upper limit, if not, then step seven is performed; if it exceeds the upper limit, then step eight is performed.

[0104] Step seven: continue to cycle steps four and five.

[0105] Step eight: the adapter 120 sends an alarm through the reminding unit (not shown) in its interior, and sends corresponding signals to the electric field generator 130 through the first communication unit 126, so that the electric field generator 130 stops providing alternating electric signals for the electrode unit 112 in the electrode piece 110, reminding the user to replace the corresponding electrode piece 110.

[0106] Step nine: turn off the power of the electric field generator 130, remove the electrode piece 110 that needs to be replaced from the adapter 120, and connect the new electrode piece 110 to the adapter 120.

[0107] Step ten: the electric field generator 130 is powered on, and continues to provide direct current power VCC to the temperature detection unit 113 in the electrode patch 110 connected to the adapter 120 for temperature detection. The ADC unit 122 in the adapter 120 collects the temperature signal detected by the temperature detection unit 113 of the replaced qualified electrode patch 110, obtains a plurality of AD sampling values, and the first controller 121 in the adapter 120 obtains a new standard encoding array A1' or / and A2' according to the aforementioned encoding rule. At least one set of new standard encoding array A1' or / and A2' is compared with the aforementioned stored corresponding standard encoding array A1 or / and A2. If the new standard encoding array A1' or / and A2' is consistent with the standard encoding array A1 or / and A2, the power of the electric field generator 130 is turned off, and the replaced new electrode patch 110 is arranged on the body surface corresponding to the tumor part of the patient. Then steps four and five are cycled. If the new standard encoding array A1' or / and A2' is compared with the aforementioned stored standard encoding A1 or / and A2, and there is at least one set of new standard encoding array A1' and / or A2' that is inconsistent with the aforementioned stored and corresponding standard encoding array A1 and / or A2, then steps nine and ten are cycled until the new standard encoding array A1' and / or A2' of the replaced qualified electrode patch 110 is consistent with the aforementioned stored and corresponding standard encoding array A1 and / or A2.

[0108] It should be noted that in the above steps, the pair of electrode patches 110 can use the same designed electrode patch 110, i.e., the standard encoding array of the pair of electrode patches 110 is the same, i.e., the standard encoding arrays A1 and A2 are the same.

[0109] The above steps one and two can be replaced by user inputting at least two sets of standard encoding arrays A1, A2. The at least two sets of standard encoding arrays A1, A2 can be stored in the adapter 120 and used as comparison encoding.

[0110] In the above step six, the number of abnormal temperature detection units 113 in the corresponding electrode patch 110 is determined by the number of inconsistent detection encoding arrays A1' and / or A2' and the corresponding standard encoding arrays A1, A2. For example, A1' is compared with A1, and only the first encoding is different, then the number of abnormal temperature detection units 113 in the corresponding electrode patch 110 is 1. For example, A1' is compared with A1, and only the last two encodings are different, then the number of abnormal temperature detection units 113 in the corresponding electrode patch 110 is 2. And so on.

[0111] In step six, the upper limit can be set to 1, i.e. one temperature detection unit 113 of the electrode sheet 110 is abnormal, and step eight is performed to alarm and replace the electrode sheet 110. In other embodiments, the upper limit in step six is not limited to 1, but can also be a positive integer close to the number of temperature detection units 113 of the electrode sheet 110.

[0112] In step eight, the reminding unit (not shown) can include at least two indicator lights (not shown) corresponding to the electrode sheet 110 one by one, indicating the state of the corresponding electrode sheet 110. When the electrode sheet 110 does not need to be replaced, the indicator lights (not shown) are green; when the electrode sheet 110 needs to be replaced, the indicator light (not shown) corresponding to the electrode sheet 110 to be replaced is red. The state of the electrode sheet 110 that does not need to be replaced or needs to be replaced can also be indicated by the indicator light (not shown) being on or flashing.

[0113] In step eight, the reminding unit (not shown) can also include a buzzer (not shown) to indicate the state of the electrode sheet 110, and the buzzer (not shown) alarms at the same time as the indicator light (not shown) to remind the user. When the electrode sheet 110 does not need to be replaced, the buzzer (not shown) does not sound an alarm; when the electrode sheet 110 needs to be replaced, the buzzer (not shown) sounds an alarm.

[0114] In steps four, five, and six, the detection code array is compared with the standard code array while temperature monitoring is also performed, and the steps include the following:

[0115] Step eleven: The first controller 121 in the adapter 120 calculates the digital temperature signal detected by the temperature detection unit 113 according to the AD sampling values, and determines whether the digital temperature signal exceeds the preset temperature. If the digital temperature signal detected by the temperature detection unit 113 of the electrode sheet 110 exceeds the preset temperature, step twelve is performed; if the digital temperature signal detected by the temperature detection unit 113 of the electrode sheet 110 is below the preset temperature, step eleven is continued.

[0116] Step twelve: When the temperature detected by the temperature detection unit 113 of the electrode sheet 110 exceeds the preset temperature, the first controller 121 in the adapter 120 sends a corresponding signal through the first communication unit 126, so that the electric field generator 130 reduces or turns off the corresponding alternating electric signal until the temperature detected by the temperature detection unit 113 of the corresponding electrode sheet 110 is below the preset temperature. The preset temperature can be in the range of 39°C to 41°C, and is preferably 40.5°C.

[0117] It should be noted that the above process takes the quality monitoring of the electrode sheet 110 by the adapter 120 as an example, and the quality monitoring of the electrode sheet 110 can also be performed by the electric field generator 130, or part of the quality monitoring can be performed by the adapter 120 and the electric field generator 130 respectively, which will not be described here in detail. In addition, the number of electrode sheets 110, the number of electrode units 112 of each electrode sheet 110, and the setting of the sampling code, etc. are all exemplary and do not limit the present application.

[0118] Specifically, in the production process of the electrode sheet 110, the first controller 121 of the adapter 120 or the second controller 131 of the electric field generator 130 can send a test code array of the electrode sheet 110 to a host computer (not shown) so that the host computer (not shown) compares the test code array with a standard code array for consistency to monitor whether each temperature detection unit 113 of the electrode sheet 110 is normally connected, and then determine whether the electrode sheet 110 is qualified, so as to screen out unqualified electrode sheets 110, thereby ensuring that each temperature detection unit 113 of the electrode sheet 110 can normally detect when it is shipped. The standard code array includes at least the first code in the first and second codes. The specific process is as follows:

[0119] Step one: provide a qualified electrode sheet 110, connect the electrode sheet 110 with the aforementioned adapter 120, connect the aforementioned adapter 120 with the aforementioned electric field generator 130, and the aforementioned electric field generator 130 is also connected with a host computer (not shown, such as a computer), and the host computer (not shown) is also connected with a display (not shown) to control the display (not shown) to display the code array (i.e. the standard code array) of the qualified electrode sheet 110 and the code array (i.e. the test code array) of the measured electrode sheet 110' of the same batch and same specification as the qualified electrode sheet 110.

[0120] Step two: power on the electric field generator 130 to provide a direct current source VCC for the temperature detection unit 113 of the qualified electrode sheet 110, and the aforementioned adapter 120 obtains a standard code array A according to the aforementioned coding rule, which is routed by the aforementioned adapter 120 to the aforementioned electric field generator 130 to the host computer (not shown), and finally stored in the host computer (not shown) as a standard code array for comparison.

[0121] Step three: provide a measured electrode sheet 110' of the same batch and same specification as the qualified electrode sheet 110, connect the measured electrode sheet 110' with the aforementioned adapter 120, and the aforementioned adapter 120 obtains a test code array B according to the aforementioned coding rule, which is routed by the aforementioned adapter 120 to the aforementioned electric field generator 130 to the host computer (not shown) and displayed on the display (not shown).

[0122] Step four: the host computer (not shown) compares the test encoding array B with the standard encoding array A for consistency. If the test encoding array B is consistent with the standard encoding array A, step five is performed. If the test encoding array B is not consistent with the standard encoding array A, step six is performed.

[0123] Step five: the display (not shown) displays that the measured electrode sheet 110’ is “qualified”, and the measured electrode sheet 110’ is placed in the good product area. Then, steps three to four are repeated to detect the next measured electrode sheet 110’.

[0124] Step six: the display (not shown) displays that the measured electrode sheet 110’ is “unqualified”, and the measured electrode sheet 110’ is placed in the defective product area. Then, steps three to four are repeated to detect the next measured electrode sheet 110’.

[0125] In step six, the display (not shown) displays that the measured electrode sheet 110’ is “unqualified”, and the host computer (not shown) controls the alarm (not shown) to alarm to alert the operator that the measured electrode sheet 110’ is “unqualified” and needs to be placed in the defective product area. The alarm (not shown) can be a sound alarm, a light alarm, etc.

[0126] It should be noted that the quality detection steps of the electrode sheet 110 described above can store the standard encoding array of a plurality of qualified electrode sheets 110 in the host computer (not shown) to form a standard encoding array library of qualified electrode sheets 110. When the same specification of the measured electrode sheet 110’ is detected again, the corresponding standard encoding array A in the standard encoding array library can be called to compare with the test encoding array B corresponding to the measured electrode sheet 110’ for detection, and to determine whether the batch of measured electrode sheets 110’ is qualified.

[0127] The encoding combination of the standard encoding array A and the test encoding array B of the corresponding measured electrode sheet 110’ in the above steps is arranged by multiple bits, which is not limited to the above Figure 2 The 20-bit encoding combination of the electrode sheet 110 of the embodiment can be arranged by 13 bits, 24 bits, etc.

[0128] The above steps are described by taking the adapter 120 to detect the quality of the electrode sheet 110 as an example. The quality of the electrode sheet 110 can also be detected by the electric field generator 130. In addition, the number of electrode sheets 110 that can be connected by the adapter 120, the number of electrode units 112 in each electrode sheet 110, and the setting of the sampling code are exemplary and do not limit the present application.

[0129] It should be noted that the control switch 124 electrically connected with the multi-path ground line 118 of the electrode sheet 110 and the bidirectional switch 125 electrically connected with the multi-path dual-purpose signal line 119 of the electrode sheet 110 in the embodiments of the present application are both arranged in the adapter 120, but in other embodiments, the control switch 124 electrically connected with the ground line 118 and the bidirectional switch 125 electrically connected with the dual-purpose signal line 119 can also be arranged on the electrode sheet 110 or in the electric field generator 130, which will not be described here. In addition, the ADC unit 122 arranged in the adapter 120 can also be arranged in the electric field generator 130 and directly controlled by the second controller 131.

[0143] It should be noted that other related descriptions about the third embodiments can refer to the related descriptions about the first embodiments, which will not be repeated here.

[0144] The substrate of the electrode sheet of the present application is electrically connected to the signal end of the same electrode unit and the corresponding temperature detection unit through the same dual-purpose signal line, which can not only transmit alternating electrical signals and direct current signals for temperature signal collection and collected temperature detection signals through the dual-purpose signal line, but also greatly reduce the number of conductive traces (ground lines, dual-purpose signal lines) laid thereon, reduce the wiring difficulty of the substrate, simplify the manufacturing process, and reduce the weight and manufacturing cost of the substrate. At the same time, the temperature of all electrode units on the electrode sheet can be monitored in real time and comprehensively without increasing the weight of the electrode sheet and the core of the first cable electrically connected to the electrode sheet, thereby realizing quality detection of the electrode sheet.

[0145] In the tumor electric field treatment system of the present application, a plurality of electrode sheets with different numbers of ground lines and dual-purpose signal lines correspond to adapters with corresponding numbers of control switches and bidirectional switches, so that there is no suspended bidirectional switch and / or control switch in the plurality of adapters, which facilitates circuit control and saves manufacturing costs.

[0146] Referring to Figure 23 The present application also provides an electrode sheet quality detection method, which includes the following steps:

[0147] S110: Determine the temperature detection signal of each electrode unit in the electrode sheet.

[0148] Specifically, referring to Figure 2 The switching unit is controlled to make the dual-purpose signal line 119 corresponding to at least one column group in the corresponding electrode sheet 110 connected to the corresponding temperature sampling point; the control switch 124 corresponding to each row group is controlled to sample the analog temperature signal of the corresponding electrode unit 112 based on the corresponding temperature sampling point, so as to determine the temperature detection signal of each electrode unit 112 in each electrode sheet 110.

[0149] S120: Determine the test code array of the electrode sheet according to the temperature detection signal.

[0150] Specifically, the temperature detection signal is characterized by a voltage value, and determining the test code array of the electrode sheet 110 according to the temperature detection signal includes: determining a voltage interval in which the voltage value is located; determining a corresponding code of the temperature detection unit 113 according to the voltage interval in which the voltage value is located, wherein different voltage intervals correspond to different codes; and generating the test code array of the corresponding electrode sheet 110 according to the code corresponding to each temperature detection unit 113. For example, the test code array includes at least one of a first code, a second code and a third code, wherein the first code is used to indicate that the temperature detection unit 113 is in a normal state, the second code is used to indicate that the temperature detection unit 113 is in an open circuit state or an uninstalled state, and the third code is used to indicate that the temperature detection unit 113 is in a short circuit state.

[0151] S130: consistency comparison between the test code array and the standard code array is performed to detect the quality of the electrode sheet.

[0152] Specifically, the test code array and the standard code array can be compared for consistency during use of the electrode sheet 110 to identify the failure condition of each temperature detection unit 113 in the corresponding electrode sheet 110, so as to realize quality detection of the electrode sheet 110 during use. When a faulty temperature detection unit 113 in the electrode sheet 110 is identified, the tumor electric field treatment system 100 is controlled to issue a first reminder information, and the electric field generator 130 is controlled to continue to work.

[0153] After the consistency comparison between the test code array and the standard code array, the number of faulty temperature detection units 113 in the electrode sheet 110 is also determined, and whether the electrode sheet 110 needs to be replaced is determined according to the number of faulty temperature detection units 113 in the electrode sheet 110. When it is determined that the electrode sheet 110 needs to be replaced, the tumor electric field treatment system 100 is controlled to issue a second reminder information, and the electric field generator 130 is controlled to stop working.

[0154] Specifically, the test code array and the standard code array can be compared for consistency during production of the electrode sheet 110 to determine whether the corresponding electrode sheet 110 is qualified, so as to realize quality detection of the electrode sheet 110 during production. After determining whether the corresponding electrode sheet 110 is qualified, the test code array of the electrode sheet 110, the standard code array and the determination result of whether the electrode sheet 110 is qualified can be displayed, and a corresponding reminder information can be issued when the electrode sheet 110 is unqualified.
