Description

[0001] This application is a divisional application of the invention patent application filed on December 30, 2022, with application number 202211722169.9 and invention title "Electrode sheet, electrode sheet identification method, tumor electric field therapy system and treatment device". Technical Field

[0002] This invention relates to the field of medical device technology, and in particular to an electrode pad, a tumor electric field therapy system, and a treatment device. Background Technology

[0003] Currently, tumor electric field therapy (TEF) systems mainly consist of an electric field generator, an adapter electrically connected to the electric field generator, and multiple pairs of electrode pads electrically connected to the electric field generator via the adapter. The electric field generator transmits alternating electrical signals for TGF therapy to each electrode pad via the adapter, and then applies an alternating electric field to the patient's tumor site for TGF therapy. Because tumors are distributed in different locations, the intensity and coverage of the electric field vary depending on the location of the tumor. For example, when the tumor is in the head, the electric field coverage is not very large, and two pairs of electrode pads with nine electrode pad units are sufficient. When the tumor is in the chest or abdomen, the electric field coverage is larger than that of the head, requiring more electrode pad units, such as those with 13, 20, or more than nine electrode pad units.

[0004] During tumor electric field therapy, the electric field applied to the patient generates heat at the corresponding locations on the skin where the electrode pads are applied. To prevent low-temperature burns, a temperature sensor is required at each electrode pad unit to monitor the skin surface temperature. Depending on the location of the tumor and the area to be covered by the tumor electric field therapy, there are situations where two pairs of electrodes with different numbers of electrode pad units need to be used together. Correspondingly, the number of temperature sensors required for electrode pads with different numbers of electrode pad units also differs. For example, electrode pads with 9, 13, and 20 electrode pad units all require different numbers of temperature sensors, and the adapter needs to collect analog temperature signals from these 9, 13, and 20 temperature sensors respectively.

[0005] In related technologies, adapters use the same acquisition program to collect analog temperature signals from the temperature sensors on their connected electrode plates. However, this can lead to interference with the analog temperature signals or the inability to acquire some temperature sensors. For example, if an adapter acquires 20 temperature sensors from a pair of electrode plates with 20 electrode plate units using the same acquisition program, it will obtain 40 analog temperature signals. If the adapter uses the same acquisition program to acquire temperature sensors from a pair of electrode plates with 13 electrode plate units, it will also acquire 40 analog temperature signals. Of these 40 signals, only 26 are from the temperature sensors on the pair of electrode plates with 13 electrode plate units; the other four are interference signals. However, the adapter cannot identify which analog temperature signals are the desired signals. If the adapter acquires temperature sensors from a pair of electrode plates with 13 electrode units and a pair of electrode plates with 20 electrode units connected to it according to the acquisition program for acquiring 13 temperature sensors, then all temperature sensors on the electrode plates with 13 electrode units can be acquired by the adapter, but 7 temperature sensors on the electrode plates with 20 electrode units will not be acquired by the adapter. Summary of the Invention

Detailed Implementation

[0048] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0049] refer to Figures 1 to 7 As shown, the tumor electric field therapy system 1000 includes: at least one pair of electrode pads 30, an adapter 50, and an electric field generator 70. The at least one pair of electrode pads 30 can be disposed in pairs on the patient's body surface, such as... Figure 1 The device comprises four electrode pads 30, with each pair of electrode pads 30 positioned on the patient's body surface. An adapter 50 is electrically connected to each electrode pad 30, and an electric field generator 70 is electrically connected to the adapter 50. The electric field generator 70 generates an alternating electric signal for tumor electric field treatment and transmits this signal to each electrode pad 30 via the adapter 50, thereby applying an alternating electric field to the patient's tumor site for tumor therapy.

[0050] refer to Figures 2 to 4 As shown, the electrode sheet 30 includes a backing 36, an electrical functional component 31 supported by the backing 36, a first cable 35 electrically connected to the electrical functional component 31, multiple support members 37 surrounding corresponding portions of the electrical functional component 31, and multiple adhesive members 38 adhering to the surface of the support members 37 away from the backing 36. The electrical functional component 31 includes a substrate 32, multiple electrode sheet units 33 disposed on the substrate 32, and multiple temperature detection units 34. Each electrode sheet unit 33 can be subjected to an alternating electric field, and each temperature detection unit 34 is disposed corresponding to one electrode sheet unit 33 to detect the temperature at the corresponding electrode sheet unit 33. Figure 4 As shown, the electrical functional component 31 includes a substrate 32 arranged in a grid pattern, a plurality of electrode pad units 33 spaced apart on the substrate 32 and applying an alternating electric field to the patient, and a plurality of temperature detection units 34 assembled on the substrate 32. Each electrode pad unit 33 has a through hole 331, which is suitable for mounting the temperature detection unit 34. For example, each electrode pad unit 33 has a through hole 331 in the middle, and each temperature detection unit 34 is received in the through hole 331 of the corresponding electrode pad unit 33. In this embodiment, there are 20 electrode pad units 33 and 20 temperature detection units 34 in the electrode pad 30. Optionally, the electrode pad unit 33 is a dielectric element, such as a ceramic sheet. The electrical functional component 31 also includes a support plate 39 located on the side of the substrate 32 away from the electrode pad units 33, providing strength support for the substrate 32. Each support member 37 has a plurality of through holes 371, and the electrode pad units 33 are respectively received in the through holes 371 of the corresponding support member 37. A plurality of adhesive pieces 38 correspond one-to-one with the corresponding support members 37.

[0051] The multiple electrode sheet units 33 of the electrode sheet 30 are arranged in a general array, such as Figures 1 to 4 As shown, the 20 electrode units 33 are arranged in a four-row, six-column configuration. The first and fourth rows each contain four electrode units 33, with each of these units located in columns two through five. The middle two rows each contain six electrode units 33, with each of these units located in columns one through six. Alternatively, the 20 electrode units 33 can be arranged in a four-row, five-column configuration, with five electrode units 33 in each row. The spatial arrangement of the multiple temperature detection units 34, corresponding one-to-one with each electrode unit 33, is roughly the same as the array arrangement of the multiple electrode units 33.

[0052] refer to Figure 5 As shown, multiple electrode pad units 33 are connected in parallel via the same conductive trace (AC line) on the substrate 32. Alternating electrical signals are transmitted through the conductive trace (AC line), forming a therapeutic electric field for tumor treatment between the electrode pads 30 and the corresponding electrode pads 30. The multiple electrode pad units 33 and multiple temperature detection units 34 are configured in at least three row groups and at least three column groups in their circuit connections. In this embodiment, the 20 electrode pad units 33 are grouped according to the order of detection positions 1 to 20, forming four row groups and five column groups, i.e., the 20 electrode pad units 33 are arranged in a four-row, five-column configuration. Since the multiple temperature detection units 34 are configured one-to-one with the multiple electrode pad units 33, the multiple temperature detection units 34 are also arranged in a four-row, five-column configuration in their circuit connections. It should be noted that this arrangement is for clearer illustration of the electrical connection between the electrode pads 30 and the adapter 50, and does not represent the spatial arrangement of the electrode pad units 33. The spatial structure may be as follows: Figure 1 The structure shown is roughly in an array.

[0053] Each temperature detection unit 34 has a signal terminal (unlabeled) and a ground terminal (unlabeled). The signal terminals (unlabeled) of the corresponding temperature detection units 34 in each column group are connected together as temperature sampling points. The ground terminals (unlabeled) of the corresponding temperature detection units 34 in each row group are connected to the ground pin GND through a control switch. The ground terminals (unlabeled) of the corresponding temperature detection units 34 in different row groups are connected to the ground pin GND through different control switches. This allows the temperature signals detected by the corresponding temperature detection units 34 in each row group to be simultaneously sampled by the corresponding temperature sampling points by configuring the on / off states of the control switches. The analog temperature signal detected by each sampled temperature detection unit 34 is used to characterize the type of electrode sheet 30. Figure 5As shown, in this embodiment, the ground terminals (unlabeled) of the five temperature detection units 34 located in each row group are all shorted in parallel through the same conductive trace (such as conductive trace 1, 2, 3 or 4) of the substrate 32. The signal terminals (unlabeled) of the five temperature detection units 34 located in each row group are connected in parallel through five conductive traces (such as conductive traces 5, 6, 7, 8 and 9) of the substrate 32. The signal terminals (unlabeled) of the temperature detection units 34 located in each column group are all shorted in parallel through the same conductive trace (such as conductive trace 5, 6, 7, 8 or 9) of the substrate 32. The ground terminals (unlabeled) of the temperature detection units 34 located in each column group are connected in parallel through four conductive traces (such as conductive traces 1, 2, 3 and 4) of the substrate 32.

[0054] refer to Figure 5 As shown, each temperature detection unit 34 includes a temperature sensor 341 and a diode 342. The temperature sensor 341 has a signal terminal 341A and a ground terminal 341B. The diode 342 has an anode 342A and a cathode 342B. The anode 342A of the diode 342 is connected to the ground terminal 341B of the temperature sensor 341. The cathode 342B of the diode 342 serves as the ground terminal (unlabeled) of the temperature detection unit 34. The signal terminal 341A of the temperature sensor 341 serves as the signal terminal (unlabeled) of the temperature detection unit 34. During temperature detection, the diode 342 in each temperature detection unit 34 can prevent the influence of the resistance values ​​of other temperature sensors 341 on the resistance value of the detected temperature sensor 341. The end of each diode 342 furthest from the temperature sensor 341 it is connected to is shorted through the same conductive trace (such as conductive traces 1, 2, 3, or 4) on the substrate 32.

[0055] refer to Figures 5 to 6 As shown, the adapter 50 includes a main control board electrically connected to the first connector 40. The main control board includes a controller 51, an ADC sampling unit 52, multiple switch units 54 composed of multiple corresponding control switches (such as control switches K1, K2, K3, and K4), and a serial communication unit 56. The controller 51 is used to configure the switching states of the multiple control switches of the multiple switch units 54. The ADC sampling unit 52 is connected to the controller 51 and is used to simultaneously sample the analog temperature signal detected by the corresponding temperature detection unit 34 in each row group through the corresponding temperature sampling point, obtain several AD sampling values, and send the several AD sampling values ​​to the controller 51 so that the controller 51 can identify the type of the corresponding electrode 30 based on the several AD sampling values.

[0056] In this embodiment, the controller 51 selectively controls the on and off of any one of the four control switches in the switching unit 54 to selectively enable any row of temperature detection units 34 in the 20 temperature detection units 34 to detect the temperature of the electrode sheet. The ADC sampling unit 52 simultaneously acquires the analog temperature signal detected by the group of temperature detection units 34 through the corresponding temperature sampling point to obtain several AD sampling values, converts the AD sampling values ​​to obtain a digital temperature signal, and transmits the AD sampling values ​​to the controller 51 so that the controller 51 can identify the type of the corresponding electrode sheet 30 based on the several AD sampling values.

[0057] The ADC sampling unit 52 has multiple acquisition channels, and the number of acquisition channels is greater than or equal to the number of column groups. In this embodiment, as shown... Figure 5 As shown, the ADC sampling unit 52 has five acquisition channels 1, 2, 3, 4, and 5. Each acquisition channel acquires only the analog temperature signal detected by the corresponding temperature detection unit 34 at any given time to obtain an AD sample value. This AD sample value is a voltage value, meaning the analog temperature signal is a voltage value. In the switching unit 54, only one of the four control switches is turned on at any given time, while the other three are turned off. This allows the ADC sampling unit 52 to acquire the analog temperature signals detected by the group of temperature detection units 34 that are short-circuited to the turned-on control switch. Specifically, as shown... Figure 5As shown, the grounding terminals (unlabeled) of temperature detection units 34 numbered 1, 2, 3, 4, and 5 are shorted together and connected to the grounding pin GND through the control switch K1 in the switching unit 54 within the adapter 50. The signal terminals (unlabeled) of temperature detection units 34 numbered 1, 2, 3, 4, and 5 are connected to the acquisition channels 1-5 of the ADC sampling unit 52 through their respective temperature sampling points. The grounding terminals (unlabeled) of temperature detection units 34 numbered 6, 7, 8, 9, and 10 are shorted together and connected to the grounding pin GND through the control switch K2 in the switching unit 54 within the adapter 50. The signal terminals (unlabeled) of temperature detection units 34 numbered 6, 7, 8, 9, and 10 are connected to the acquisition channels 1-5 of the ADC sampling unit 52 through their respective temperature sampling points. The grounding terminals (unlabeled) of temperature detection units 34 numbered 2, 13, 14, and 15 are shorted together and connected to the grounding pin GND via the control switch K3 in the switching unit 54 within the adapter 50. The signal terminals (unlabeled) of temperature detection units 34 numbered 11, 12, 13, 14, and 15 are connected to the acquisition channels 1-5 of the ADC sampling unit 52 via their respective temperature sampling points. The grounding terminals (unlabeled) of temperature detection units 34 numbered 16, 17, 18, 19, and 20 are shorted together and connected to the grounding pin GND via the control switch K4 in the switching unit 54 within the adapter 50. The signal terminals (unlabeled) of temperature detection units 34 numbered 16, 17, 18, 19, and 20 are connected to the acquisition channels 1-5 of the ADC sampling unit 52 via their respective temperature sampling points. Simultaneously, each temperature sampling point is connected to the DC power supply VCC via the corresponding voltage divider resistor 53 within the adapter 50.

[0058] Optionally, the temperature sensor 341 in the temperature detection unit 34 is a thermistor. For example, the temperature sensor 341 is a negative temperature coefficient thermistor, characterized by a lower resistance at higher temperatures and a higher resistance at lower temperatures. Since the electrode pad 30 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, a thermistor with model number NCP18XH103D03RB can be selected. When the sensed temperature is 0℃, the corresponding resistance is approximately 27.45KΩ; when the sensed temperature is 25℃, the corresponding resistance is approximately 10.0KΩ; and when the sensed temperature is 50℃, the corresponding resistance is approximately 4.16KΩ.

[0059] like Figure 5 and Figure 7As shown, when any one of the control switches in the control switch unit 54 of the controller 51 is turned on, the DC power supply VCC provides DC power to the voltage divider resistor 53, the temperature sensor 341 and the diode 342 in sequence. The ADC sampling unit 52 in the adapter 50 collects the voltage between the temperature sensor 341 and the voltage divider resistor 53 through the corresponding acquisition channel, that is, the voltage division between the temperature sensor 341 and the diode 342 and the voltage divider resistor 53, and obtains the AD sampling value, that is, the voltage value (the voltage value of the thermistor), as shown in the following formula (1):

[0060] VADC=(VCC-VD)×R / (Rz+R) (1)

[0061] 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 the diode; R is the resistance of the thermistor; and Rz is the resistance of the voltage divider resistor.

[0062] Assuming the diode voltage drop VD is 0.3V and the voltage divider resistor Rz is 10KΩ, then when the temperature sensed by temperature sensor 341 is 0℃, the corresponding resistance is approximately 27.45KΩ. Based on 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 sensed by temperature sensor 341 is 25℃, the corresponding resistance is approximately 10.0KΩ. Based on formula (1), the corresponding AD sampling value V25 = (3.3-0.3)×10 / (10+10) = 1.50V can be obtained. When the temperature sensed by temperature sensor 341 is 50℃, the corresponding resistance is approximately 4.16KΩ. Based on formula (1), the corresponding AD sampling value V50 = (3.3-0.3)×4.16 / (10+4.16) = 0.88V can be obtained. When temperature sensor 341 is disconnected, for example, due to improper soldering or an open circuit, the corresponding AD sampling value is 3.3V. When temperature sensor 341 and diode 342 are short-circuited, the corresponding AD sampling value is 0V.

[0063] Since the ADC sampling unit 52 collects the voltage value of the temperature sensor 341, and the temperature sensor 341 has different voltage values ​​corresponding to different temperatures, the voltage value collected by the ADC sampling unit 52 can be reasonably segmented for differentiation. At the same time, the voltage value is converted into a corresponding code to identify the type of electrode sheet 30, that is, the number of electrode sheet units 33 on the electrode sheet 30.

[0064] Specifically, taking the temperature sensor 341 sensing a temperature range of 0℃ to 50℃, and the AD sampling value obtained by the ADC sampling unit 52 sampling a voltage range of 0.88V to 2.20V as an example, considering factors such as detection error, the voltage range can be appropriately expanded to 0.5V to 3V.

[0065] When the AD sampling value obtained by the ADC sampling unit 52 is greater than 0.5V and less than 3V, the corresponding acquisition code is 1; when the AD sampling value obtained by the ADC sampling unit 52 is less than or equal to 0.3V, the corresponding acquisition code is 0; when the AD sampling value obtained by the ADC sampling unit 52 is greater than or equal to 3.1V, the corresponding acquisition code is 2. Therefore, in the corresponding detection positions numbered 1 to 20 of the electrode plate 30, if the temperature sensor 341 is short-circuited, the corresponding code is 0; if the temperature sensor 341 is present, the corresponding code is 1; if the temperature sensor 341 is absent or disconnected, the corresponding code is 2.

[0066] refer to Figure 5 As shown, during sampling, regardless of the type of electrode 30 (i.e., the number of electrode units 33 or temperature sensors 341 of the electrode 30 is less than or equal to 20), the ADC sampling unit 52 acquires 20 AD sampling values ​​each time, and after each acquisition, it forms a 20-bit encoding array based on the 20 AD sampling values. Each type of electrode 30 has a corresponding encoding array, so the type of electrode 30 can be automatically identified through the encoding array.

[0067] The controller 51 can determine the encoding array of the corresponding electrode 30 based on several AD sampling values, and determine the type of the corresponding electrode 30 based on the encoding array. For example... Figure 5 As shown, when the electrode sheet 30 has 20 electrode sheet units 33, and each electrode sheet unit 33 includes a temperature sensor 341 and a diode 342, that is, the corresponding detection positions of the electrode sheet 30 numbered 1 to 20 all have temperature sensors 341 and the codes are all 1. The 20 codes are combined to obtain a 20-bit code array 1111111111 11111 11111.

[0068] like Figure 8As shown, when the electrode plate 30 has 9 electrode plate units 33 and 9 temperature detection units 34, the 9 electrode plate units 33 and 9 temperature detection units 34 are arranged in two rows and five columns in the circuit connection, and the 9 electrode plate units 33 and 9 temperature detection units 34 are arranged sequentially. A wire (unlabeled) is shorted at a corresponding position of the 9 temperature detection units 34. That is, a wire (unlabeled) is set at the intersection of the two rows and five columns in the circuit connection and shorted to the ground terminal (unlabeled) of the temperature detection unit 34 in the same row group, and at the same time shorted to the signal terminal (unlabeled) of the temperature detection unit 34 in the same column group. Each temperature detection unit 34 includes a temperature sensor 341 and a diode 342, with corresponding detection bit numbers from 1 to 9. That is, each detection bit numbered 1 to 9 of the electrode plate 30 has a temperature sensor 341, and the code is 1. Unlike the electrode plate 30 with 20 electrode plate units 33, the next detection bit (i.e., the corresponding detection bit number 10) does not have an electrode plate unit 33 (no temperature sensor 341) and is shorted by a wire (unlabeled), with a corresponding code of 0. The corresponding detection bit numbers 11 to 20 do not have an electrode plate unit 33 (no temperature sensor 341) and are not shorted by a wire (unlabeled), and are in an open state, with a corresponding code of 2. Therefore, the 20-bit code is combined to obtain a 20-bit code array 11111 11110 22222 22222.

[0069] like Figure 9As shown, when the electrode plate 30 has 13 electrode plate units 33 and 13 temperature detection units 34, the 13 electrode plate units 33 and 13 temperature detection units 34 are arranged in three rows and five columns in the circuit connection, and the 13 electrode plate units 33 and 13 temperature detection units 34 are arranged sequentially. A wire (unlabeled) is shorted at a corresponding position of the 13 temperature detection units 34. That is, a wire (unlabeled) is set at the intersection of the three rows and four columns in the circuit connection and shorted to the ground terminal (unlabeled) of the temperature detection unit 34 in the same row group, and at the same time shorted to the signal terminal (unlabeled) of the temperature detection unit 34 in the same column group. Each electrode unit 33 includes a temperature sensor 341 and a diode 342, with corresponding detection bit numbers from 1 to 13. That is, each detection bit numbered 1 to 13 of the electrode 30 has a temperature sensor 341, and the code is 1. Unlike the electrode 30 with 20 electrode units 33, the next detection bit (i.e., the corresponding detection bit number 14) does not have an electrode unit 33 (no temperature sensor 341) and is shorted in parallel by wires (unlabeled), with a corresponding code of 0. The corresponding detection bit numbers 15 to 20 do not have an electrode unit 33 (no temperature sensor 341) and are not shorted in parallel by wires (unlabeled), and are in an open state, with a corresponding code of 2. Therefore, the 20-bit code is combined to obtain a 20-bit code array of 11111 11111 11102 22222.

[0070] like Figure 10 As shown, when the electrode plate 30 has 19 electrode plate units 33 and 19 temperature detection units 34, the 19 electrode plate units 33 and 19 temperature detection units 34 are arranged in a four-row group and a five-column group in the circuit connection, and the 19 electrode plate units 33 and 19 temperature detection units 34 are arranged sequentially. A wire (unlabeled) is shorted at a corresponding position of the 19 temperature detection units 34. That is, a wire (unlabeled) is set at the intersection of the four-row group and the five-column group in the circuit connection and shorted to the ground terminal (unlabeled) of the temperature detection unit 34 in the same row group, and at the same time shorted to the signal terminal (unlabeled) of the temperature detection unit 34 in the same column group. Each electrode unit 33 includes a temperature sensor 341 and a diode 342, with corresponding detection bit numbers from 1 to 19. That is, each detection bit numbered 1 to 19 of the electrode 30 has a temperature sensor 341, and the code is 1. Unlike the electrode 30 with 20 electrode units 33, the next detection bit (i.e., the corresponding detection bit number 20) does not have an electrode unit 33 (no temperature sensor 341) and is shorted in parallel by wires (unlabeled), with a corresponding code of 0. Therefore, the 20-bit code is combined to obtain a 20-bit code array of 11111 1111111111 11110.

[0071] When the adapter 50 is not connected to the electrode plate 30, the ADC sampling unit 52 samples the voltage of the DC power supply VCC, which is 3.3V. Therefore, the 20-bit encoding array is 22222 22222 22222 22222.

[0072] Based on the above patterns, we can conclude that: the electrode 30 with one electrode unit 33 and one temperature detection unit 34 corresponds to the encoding array 10222 22222 22222 22222; the electrode 30 with two electrode units 33 and two temperature detection units 34 corresponds to the encoding array 11022 22222 22222 22222; the electrode 30 with three electrode units 33 and three temperature detection units 34 corresponds to the encoding array 11102 22222 22222 22222; the electrode 30 with four electrode units 33 and four temperature detection units 34 corresponds to the encoding array 11110 2222222222 22222; and the electrode 30 with five electrode units 33 and five temperature detection units 34 corresponds to the encoding array 11111. 022222222 22222; Electrode 30 with 6 electrode units 33 and 6 temperature detection units 34, corresponding to the encoding array 11111 10222 22222 22222; Electrode 30 with 7 electrode units 33 and 7 temperature detection units 34, corresponding to the encoding array 11111 11022 22222 22222; Electrode 30 with 8 electrode units 33 and 8 temperature detection units 34, corresponding to the encoding array 11111 11102 2222222222; Electrode 30 with 9 electrode units 33 and 9 temperature detection units 34, corresponding to the encoding array 11111 11110 22222 22222; Electrode sheet 30 with 10 electrode units 33 and 10 temperature detection units 34, corresponding to the encoding array 11111 11111 02222 22222; Electrode sheet 30 with 11 electrode units 33 and 11 temperature detection units 34, corresponding to the encoding array 11111 1111110222 22222; Electrode sheet 30 with 12 electrode units 33 and 12 temperature detection units 34, corresponding to the encoding array 11111 11111 1102222222; Electrode sheet 30 with 13 electrode units 33 and 13 temperature detection units 34, corresponding to the encoding array 11111 11111 11102 22222; Electrode sheet 30 with 14 electrode units 33 and 14 temperature detection units 34, corresponding to the encoding array 11111. 11111 11110 22222; The electrode sheet 30 with 15 electrode sheet units 33 and 15 temperature detection units 34 has a corresponding encoding array of 11111 11111 11111 02222; The electrode sheet 30 with 16 electrode sheet units 33 and 16 temperature detection units 34 has a corresponding encoding array of 11111 111111111110222;The electrode 30 with 17 electrode units 33 and 17 temperature detection units 34 has a corresponding encoding array of 11111 11111 11111 11022; the electrode 30 with 18 electrode units 33 and 18 temperature detection units 34 has a corresponding encoding array of 11111 11111 11111 11102; the electrode 30 with 19 electrode units 33 and 19 temperature detection units 34 has a corresponding encoding array of 11111 11111 11111 11110; the electrode 30 with 20 electrode units 33 and 20 temperature detection units 34 has a corresponding encoding array of 11111 11111 1111111111; when the adapter 50 is not connected to the electrode 30, the corresponding encoding array is 22222 22222 22222. 22222. ;

[0073] All 21 numbered arrays are different. Therefore, when the electrode plate 30 is normal, the controller 51 can determine the type of electrode plate 30 connected to the adapter 50 or whether the electrode plate 30 is connected by the encoding array.

[0074] When the type of electrode 30 is determined, the controller 51 also determines whether the corresponding electrode 30 has a temperature detection fault according to the encoding array. The analog temperature signal detected by each sampled temperature detection unit 34 is also used to characterize whether the electrode 30 has a temperature detection fault.

[0075] like Figure 5 As shown, in an electrode 30 with 20 electrode units 33 and 20 temperature detection units 34, if the temperature sensor 341 numbered 20 is damaged (open circuit), the AD sampling value obtained by the ADC sampling unit 52 is 3.3V, the corresponding sampling code is 2, and the corresponding abnormal code array is 11111 11111 1111111112. This code array is inconsistent with the normal code array 11111 11111 11111 11111, so the controller 51 can distinguish the temperature detection fault.

[0076] like Figure 8 As shown, in the electrode 30 with 9 electrode units 33 and 9 temperature detection units 34, assuming that the temperature sensor 341 numbered 1 is damaged (open circuit), the AD sampling value obtained by the ADC sampling unit 52 is 3.3V, the corresponding sampling code is 2, and the corresponding abnormal code array is 21111 11110 22222 22222. This code array is inconsistent with the normal code array 11111 11110 22222 22222. Therefore, the controller 51 can distinguish the temperature detection fault.

[0077] In summary, when the temperature sensor 341 of electrode 30 is functioning normally, the code "0" in the corresponding 20-bit encoding array is not the last bit, and all codes before the code "0" are "1", and all codes after the code "0" are "2"; or, the code "0" is the last bit and all codes before the code "0" are "1"; or, all codes in the 20-bit encoding array are "1". When the temperature sensor 341 of electrode 30 is damaged, regardless of whether the code "0" in the corresponding 20-bit encoding array is the last bit, the codes before the code "0" will be different from "1" (code "2"), or all codes in the 20-bit encoding array will be "1" or "2".

[0078] refer to Figure 1 As shown, each electrode 30 is connected to the adapter 50 by a first connector 40. The first connector 40 is adapted to connect the corresponding electrode 30 to the adapter 50. The first connector 40 includes a first plug 41 located at the end of the first cable 35 away from the electrical functional component 31 and a first socket 42 located on the adapter 50. The first plug 41 and the first socket 42 are push-button spring connectors, that is, the first connector 40 connects the adapter 50 and the electrode 30 by means of a connector.

[0079] A second connector 60 is provided between the adapter 50 and the electric field generator 70, and the second connector 60 is adapted to connect the electric field generator 70 to the adapter 50. The adapter 50 also includes a second cable 55 that connects to the second connector 60. The second connector 60 includes a second plug 61 located at the end of the second cable 55 away from the controller 51 and a second socket 62 located on the electric field generator 70. The second plug 61 and the second socket 62 are push-button spring connectors, that is, the second connector 60 connects the adapter 50 and the electric field generator 70 using a plug-in method. (Reference) Figure 6 and Figure 7 As shown, each of the first connectors, such as X1, Y1, X2, and Y2, is connected to the second connector 60 via an alternating power supply line. The first connectors, such as X1, Y1, X2, and Y2, are also connected to the switching unit 54 and the ADC sampling unit 52, respectively. The second connector 60 is connected to the serial communication unit 56 via a receive data line RX and a transmit data line TX. The VCC pin of the second connector 60 is connected to the power supply terminal of the controller 51, and the GND pin of the second connector 60 is grounded. The VCC pin of the second connector 60 is also connected to the temperature sampling point via a corresponding voltage divider resistor 53.

[0080] The controller 51 is connected to multiple switching units 54 and is connected between the ADC sampling unit 52 and the serial communication unit 56. The controller 51 can also send several AD sampling values ​​to the electric field generator 70 via the serial communication unit 56, so that the electric field generator 70 can identify the type of the corresponding electrode 30 based on the several AD sampling values ​​when the electrode is functioning normally. The electric field generator 70 is also used to determine the encoding array of the corresponding electrode 30 based on the several AD sampling values, and to determine the type of the corresponding electrode 30 based on the encoding array, and / or to determine whether the corresponding electrode 30 has a temperature detection fault based on the encoding array. In other words, under normal electrode conditions, the controller 51 or the electric field generator 70 can determine the type of the corresponding electrode 30, or a temperature detection fault, or both, based on the AD sampling values, as detailed above, and will not be repeated here.

[0081] It should be noted that the number of electrode sheets 30, the number of electrode sheet units 33 in each electrode sheet 30, and the setting of sampling codes are all illustrative examples and are not intended to limit this application.

The ground terminals (unlabeled) of the corresponding temperature detection units 34 in each row group are connected to the ground pin GND through a control switch. By configuring the switching state of the control switch, the analog temperature signal detected by the corresponding temperature detection unit 34 in each row group is simultaneously sampled by the corresponding temperature sampling points. Under normal conditions, the analog temperature signal detected by each temperature detection unit 34 sampled by the electrode 30 is used to characterize the type of electrode 30, thereby automatically identifying the type of electrode 30 and realizing temperature acquisition for different types of electrode 30 without missing acquisition or generating interference signals. Under the condition that the electrode type is determined, the analog temperature signal detected by each temperature detection unit 34 sampled by the electrode 30 is also used to characterize whether the electrode 30 has a temperature detection fault, thereby identifying abnormal temperature detection units 34.
