Description

[0001] This application is a divisional application of the invention patent application with the application date of December 30, 2022, the application number of 202211722151.9, and the invention creation name of "Tumor Electric Field Therapy System, Tumor Treatment Device and Electrode Sheet Fault Detection Method". Technical Field

[0003] Currently, a tumor electric field therapy system mainly includes an electric field generator, an adapter electrically connected to the electric field generator, and multiple pairs of electrode sheets electrically connected to the electric field generator through the adapter. The electric field generator transmits an alternating electric signal for tumor electric field therapy to each electrode sheet through the adapter, and then applies an alternating electric field to the tumor site of the patient through the electrode sheet for tumor electric field therapy. Since the alternating electric field applied to the patient will accumulate heat at the corresponding position where the electrode sheet adheres to the skin, in order to avoid low-temperature skin burns, a temperature sensor needs to be configured at each electrode sheet unit to monitor the skin surface temperature at each electrode sheet unit. However, during the process of using the electrode sheet for tumor treatment, it is inevitable that there will be an abnormal problem that a very small number of temperature sensors on some electrode sheets malfunction after being used for a period of time.

Detailed Embodiments

[0046] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where 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 drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0047] Reference Figures 1 to 4 As shown, the tumor treating electric field system 1000 includes: at least a pair of electrode plates 30, an adapter 50, and an electric field generator 70. At least a pair of electrode plates 30 are arranged in pairs on the surface of a patient's body. For example, the four electrode plates 30 in Figure 1 are arranged in pairs on the surface of the patient's body, with every two electrode plates 30 as a pair. The adapter 50 is electrically connected to each electrode plate 30, and the electric field generator 70 is electrically connected to the adapter 50. The electric field generator 70 is configured to generate an alternating electric signal for the tumor treating electric field, and transmit the alternating electric signal to each electrode plate 30 through the adapter 50, so as to generate an alternating electric field between the paired two electrode plates 30, and the alternating electric field is applied to the tumor site of the patient for tumor treating electric field therapy.

[0048] Reference Figures 1 - 2 , the electrode plate 30 includes a substrate 32, a plurality of electrode plate units 33 arranged on the substrate 32, and a plurality of temperature detection units 34. Each electrode plate unit 33 can apply an alternating electric field, and each temperature detection unit 34 is arranged corresponding to one electrode plate unit 33 to detect the temperature at the corresponding electrode plate unit 33. The electrode plate 30 further includes a backing (not shown) for supporting the substrate 32 and a first cable 35 electrically connected to the substrate 32. A first connector 40 is arranged between the electrode plate 30 and the adapter 50. The first connector 40 is adapted to connect the electrode plate 30 to the adapter 50. The first connector 40 includes a first plug 41 arranged at one end of the first cable 35 away from the electrical functional components and a first socket 42 arranged 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 plate 30 in a connector manner.

[0049] The substrate 32 of the electrode plate 30 is arranged in a grid shape, and a plurality of electrode plate units 33 and a plurality of temperature detection units 34 are arranged at intervals on the substrate 32. Each electrode plate unit 33 has a through hole 331 arranged therethrough, and the through hole 331 is adapted to install the temperature detection unit 34. In this embodiment, the through hole 331 is located in the middle of each electrode plate unit 33, and each temperature detection unit 34 is received in the through hole 331 of the corresponding electrode plate unit 33. Optionally, the electrode plate unit 33 is a dielectric element, such as a ceramic sheet. The electrode plate 30 further includes a support plate (not shown) located on the side of the substrate 32 away from the electrode plate unit 33 to provide strength support for the substrate 32, and the support plate (not shown) is clamped between the substrate 32 and the backing (not shown).

[0050] The plurality of electrode plate units 33 of the electrode plate 30 are arranged substantially in an array. Such as Figure 1As shown, 20 electrode sheet units 33 are arranged in four rows and six columns. Both the first row and the fourth row have four electrode sheet units 33, and the four electrode sheet units 33 in each of the first row and the fourth row are located in the columns from the second column to the fifth column. The middle two rows each have six electrode sheet units 33, and the six electrode sheet units 33 in each of the middle two rows are located in the columns from the first column to the sixth column. The 20 electrode sheet units 33 can also be arranged in four rows and five columns, with 5 electrode sheet units 33 in each row. The 20 electrode sheet units 33 can also be arranged in other array patterns. The spatial arrangement of multiple temperature detection units 34 arranged in one-to-one correspondence with the electrode sheet units 33 is generally the same as the array arrangement of the multiple electrode sheet units 33.

[0051] Reference Figure 2 As shown, multiple electrode sheet units 33 are connected in parallel through the same conductive trace line (AC line) of the substrate 32. They are transmitted alternating current signals by the conductive trace line (AC line) and form a treatment electric field for treating tumors between the opposite electrode sheets 30. Both the multiple electrode sheet units 33 and the multiple temperature detection units 34 are configured as at least three row groups and at least three column groups in terms of circuit connection. In this embodiment, the 20 electrode sheet units 33 are sorted and grouped in the order of detection positions from 1 to 20 in terms of circuit connection, and are divided into four row groups and five column groups, that is, the 20 electrode sheet units 33 are arranged in four rows and five columns in terms of circuit connection. Since the multiple temperature detection units 34 are arranged in one-to-one correspondence with the multiple electrode sheet units 33, the multiple temperature detection units 34 are also arranged in a four-row group and a five-column group in terms of circuit connection. It should be noted that this arrangement method is to more clearly show the electrical connection situation between the electrode sheet 30 and the adapter 50, and does not represent the arrangement of the electrode sheet units 33 in the spatial structure, and its spatial structure may be as Figure 1 shown, generally in an array structure.

[0052] Each temperature detection unit 34 has a signal terminal (not labeled) and a ground terminal (not labeled). The signal terminals (not labeled) of the corresponding temperature detection units 34 in each column group are connected together as a temperature sampling point. The ground terminals (not labeled) of the corresponding temperature detection units 34 in each row group are commonly connected to the ground pin GND through a control switch. The ground terminals (not labeled) of the corresponding temperature detection units 34 in different row groups are connected to the ground pin GND through different control switches, so as to sample the temperature signals detected by the corresponding temperature detection units 34 in each row group simultaneously by the corresponding temperature sampling point by configuring the switch states of the control switches. As Figure 2As shown, in this embodiment, the ground terminals (not labeled) of the five temperature detection units 34 in each row group are all shunted in parallel through the same conductive trace (such as conductive traces 1, 2, 3, or 4) of the substrate 32. The signal terminals (not labeled) of the five temperature detection units 34 in each row group are respectively connected in parallel through five conductive traces (such as conductive traces 5, 6, 7, 8, and 9) of the substrate 32. The signal terminals (not labeled) of the temperature detection units 34 within each column group are all shunted in parallel through the same conductive trace (such as conductive traces 5, 6, 7, 8, or 9) of the substrate 32. The ground terminals (not labeled) of the temperature detection units 34 within each column group are connected in parallel through four conductive traces (such as conductive traces 1, 2, 3, and 4) of the substrate 32.

[0053] Reference Figure 2 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 (not labeled) of the temperature detection unit 34. The signal terminal 341A of the temperature sensor 341 serves as the signal terminal (not labeled) of the temperature detection unit 34. During temperature detection, the corresponding temperature detection unit 34 can avoid the influence of the resistance values of other temperature sensors 341 on the resistance value of the detected temperature sensor 341 through the diode 342. One end of each diode 342 away from the connected temperature sensor 341 is shunted in parallel through the same conductive trace (such as conductive traces 1, 2, 3, or 4) of the substrate 32.

[0054] The adapter 50 is used to sample the analog temperature signals detected by each temperature detection unit 34 in the electrode sheet 30, periodically determine the detection coding array of the electrode sheet 30 according to the sampled analog temperature signals detected by each temperature detection unit 34, and compare the detection coding array with a preset standard coding array to identify the fault conditions of each temperature detection unit 34 in the electrode sheet 30. The preset standard coding array is the coding array when the electrode sheet 30 is qualified. Reference Figures 2 - 3 , 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, a plurality of switch units 54 respectively composed of a plurality of 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 switch states of the plurality of control switches of the plurality of switch units 54.

[0055] The ADC sampling unit 52 is connected to the controller 51. The ADC sampling unit 52 is used to sample the analog temperature signals detected by each temperature detection unit 34 to obtain a number of AD sampling values. As Figure 2 shown, the ADC sampling unit 52 simultaneously samples the analog temperature signals detected by the corresponding temperature detection units 34 in each row group through the corresponding temperature sampling points to obtain a number of AD sampling values. Specifically, the ADC sampling unit 52 has a plurality of acquisition channels, and the number of acquisition channels is greater than or equal to the number of column groups. In this embodiment, the ADC sampling unit 52 has five acquisition channels 1, 2, 3, 4, and 5. Each acquisition channel only samples the analog temperature signal detected by a corresponding temperature detection unit 34 at the same time to obtain an AD sampling value, and the AD sampling value is a voltage value, that is, the temperature signal is characterized by the voltage value. The adapter 50 further includes a DC power supply VCC and a voltage dividing unit 53. The voltage dividing unit 53 includes at least three voltage dividing resistors Rz, and each temperature sampling point is connected to the DC power supply VCC through the corresponding voltage dividing resistor Rz.

[0056] The controller 51 is used to configure the switching states of the control switches. In this embodiment, only one of the four control switches in the switch unit 54 is turned on at the same time, and the other three control switches are turned off, so that the ADC sampling unit 52 can sample the analog temperature signals detected by a group of temperature detection units 34 short-circuited by the turned-on control switch. For example, the ground terminals (not labeled) of the temperature detection units 34 numbered 1, 2, 3, 4, and 5 are short-circuited together and connected to the ground pin GND through the control switch K1 in the switch unit 54 within the adapter 50. The signal terminals (not labeled) of the temperature detection units 34 numbered 1, 2, 3, 4, and 5 are respectively connected to the acquisition channels 1-5 of the ADC sampling unit 52 through the corresponding temperature sampling points; the ground terminals (not labeled) of the temperature detection units 34 numbered 6, 7, 8, 9, and 10 are short-circuited together and connected to the ground pin GND through the control switch K2 in the switch unit 54 within the adapter 50. The signal terminals (not labeled) of the temperature detection units 34 numbered 6, 7, 8, 9, and 10 are respectively connected to the acquisition channels 1-5 of the ADC sampling unit 52 through the corresponding temperature sampling points; the ground terminals (not labeled) of the temperature detection units 34 numbered 11, 12, 13, 14, and 15 are short-circuited together and connected to the ground pin GND through the control switch K3 in the switch unit 54 within the adapter 50. The signal terminals (not labeled) of the temperature detection units 34 numbered 11, 12, 13, 14, and 15 are respectively connected to the acquisition channels 1-5 of the ADC sampling unit 52 through the corresponding temperature sampling points; the ground terminals (not labeled) of the temperature detection units 34 numbered 16, 17, 18, 19, and 20 are short-circuited together and connected to the ground pin GND through the control switch K4 in the switch unit 54 within the adapter 50. The signal terminals (not labeled) of the temperature detection units 34 numbered 16, 17, 18, 19, and 20 are respectively connected to the acquisition channels 1-5 of the ADC sampling unit 52 through the corresponding temperature sampling points.

[0057] When the ADC sampling unit 52 obtains a number of AD sampling values, it also sends the number of AD sampling values to the controller 51, so that the controller 51 can determine the detection coding array of the electrode plate 30 according to the number of AD sampling values, and compare the detection coding array with the preset standard coding array to identify the fault conditions of each temperature detection unit 34 in the electrode plate 30. In this embodiment, the controller 51 can selectively control any one of the four control switches in the switch unit 54 to be turned on and the remaining three to be turned off, so as to selectively enable any row group of temperature detection units 34 among the 20 temperature detection units 34 to detect temperature. The ADC sampling unit 52 simultaneously collects the analog temperature signals detected by the group of temperature detection units 34 through the corresponding temperature sampling points to obtain a number of AD sampling values, and transmits the AD sampling values to the controller 51. The controller 51 determines the detection coding array of the electrode plate 30 according to the number of AD sampling values, and compares the detection coding array with the preset standard coding array to identify the fault conditions of each temperature detection unit 34 in the electrode plate 30.

[0058] The adapter 50 further includes a reminder unit (not shown). The reminder unit (not shown) is connected to the controller 51. When there is a faulty temperature detection unit 34 in the electrode plate 30, the controller 51 controls the reminder unit (not shown) to send a first reminder message and instructs the electric field generator 70 to continue working. For example, when there is no faulty temperature detection unit 34 in the electrode plate 30, the controller 51 controls the reminder unit (not shown), such as an indicator light, to turn green, and when there is a faulty temperature detection unit 4 in the electrode plate 30, the controller 51 controls the reminder unit (not shown), such as an indicator light, to turn red.

[0059] When comparing the detection coding array with the preset standard coding array, the controller 51 also determines the number of faulty temperature detection units 34 in the electrode plate 30 and judges whether the electrode plate 30 needs to be replaced according to the number. For example, when the number exceeds the preset number (the minimum can be set to 1), it is judged that the electrode plate 30 needs to be replaced, and when the number does not exceed the preset number, it is judged that the electrode plate 30 does not need to be replaced. When judging that the electrode plate 30 needs to be replaced, the controller 51 can also control the reminder unit (not shown) to send a second reminder message and instruct the electric field generator 70 to stop working. For example, when judging that the electrode plate 30 needs to be replaced, the controller 51 controls the reminder unit (not shown), such as an indicator light, to turn red and flash, and at the same time can control the reminder unit (not shown), such as a buzzer, to alarm, and can also send a corresponding signal to the electric field generator 70 through the serial communication unit 56, so that the electric field generator 70 stops outputting the alternating electric signal.

[0060] During the tumor electric field treatment process of the electrode patch 30, the adapter 50 periodically performs the aforementioned fault detection of the electrode patch 30 to replace the electrode patch 30 in a timely manner. In addition to periodically performing the aforementioned fault detection of the electrode patch 30, the adapter 50 also obtains a number of AD sampling values based on the analog temperature signals detected by each temperature detection unit 34 sampled, and transmits the AD sampling values to the controller 51. The controller 51 converts the number of AD sampling values to obtain a digital temperature signal to determine the temperature at the corresponding electrode patch unit 33. The controller 51 sends the digital temperature signal to the electric field generator 70 through the serial communication unit 56. When the electric field generator 70 identifies that the electrode patch 30 has an over-temperature situation based on the temperature at the corresponding electrode patch unit 33, the electric field generator 70 reduces the amplitude of the alternating electric signal or stops outputting the alternating electric signal. In this embodiment, the controller 51 can calculate the temperature at each electrode patch unit 33 in the electrode patch 30 based on a number of AD sampling values, and then compare the temperature with a preset temperature. If the temperature exceeds the preset temperature, it is considered that the electrode patch 30 has an over-temperature situation. At this time, a corresponding signal can be sent to the electric field generator 70 through the serial communication unit 56 so that the electric field generator 70 stops outputting the alternating electric signal or reduces the amplitude of the alternating electric signal. Among them, the range of the preset temperature can be 39°C to 41°C, preferably 40.5°C.

[0061] Reference Figure 1 As shown, the adapter 50 further includes a second cable 55 connected to the electric field generator 70. A second connector 60 is provided between the adapter 50 and the electric field generator 70. The second connector 60 is adapted to connect the electric field generator 70 to the adapter 50. The second connector 60 includes a second plug 61 provided at one end of the second cable 55 away from the controller 51 and a second socket 62 provided 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 in a plug-and-socket manner. Reference Figure 3 As shown, when there are 4 first connectors 40, each first connector such as X1, Y1, X2, and Y2 is connected to the second connector 60 through an alternating power line. The first connectors such as X1, Y1, X2, and Y2 are also respectively connected to the switch unit 54 and the ADC sampling unit 52. The second connector 60 is connected to the serial communication unit 56 through 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. 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 through a corresponding voltage dividing resistor Rz.

[0062] In other embodiments, the controller 51 can also send a number of AD sampling values to the electric field generator 70 through the serial communication unit 56, the second cable 55, and the second connector 60, so that the electric field generator 70 can determine the detection coding array of the electrode plate 30 according to the number of AD sampling values, and compare the detection coding array with a preset standard coding array to identify the fault conditions of each temperature detection unit 34 in the electrode plate 30. When there is a fault in the temperature detection unit 34 in the electrode plate 30, the electric field generator 70 also issues a first reminder message and continues to output an alternating electric signal. For example, the electric field generator 70 can include a reminder unit (not shown). When there is no fault in the temperature detection unit 34 in the electrode plate 30, the electric field generator 70 controls the reminder unit (not shown) such as an indicator light to turn green, while when there is a fault in the temperature detection unit 4 in the electrode plate 30, the electric field generator 70 controls the reminder unit (not shown) such as an indicator light to turn red.

[0063] When comparing the detection coding array with the preset standard coding array, the electric field generator 70 also determines the number of faulty temperature detection units 34 in the electrode plate 30 and judges whether the electrode plate 30 needs to be replaced according to the number. For example, when the number exceeds the preset number, it is judged that the electrode plate 30 needs to be replaced, while when the number does not exceed the preset number, it is judged that the electrode plate 30 does not need to be replaced. When judging that the electrode plate 30 needs to be replaced, the electric field generator 70 also issues a second reminder message and stops outputting the alternating electric signal. For example, when judging that the electrode plate 30 needs to be replaced, the electric field generator 70 controls the reminder unit (not shown) such as an indicator light to turn red and flash, and at the same time can control the reminder unit (not shown) such as a buzzer to alarm, and at the same time stops outputting the alternating electric signal.

[0064] The electric field generator 70 also determines the temperature at the corresponding electrode plate unit 33 according to a number of AD sampling values, and when identifying that the electrode plate 30 has an over-temperature condition according to the temperature at the corresponding electrode plate unit 33, reduces the amplitude of the alternating electric signal or stops outputting the alternating electric signal. For example, the electric field generator 70 can calculate the temperature at each electrode plate unit 33 in the electrode plate 30 based on a number of AD sampling values, and then compare the temperature with a preset temperature. If the temperature exceeds the preset temperature, it is considered that the electrode plate 30 has an over-temperature condition, and at this time, the output of the alternating electric signal can be stopped or the amplitude of the alternating electric signal can be reduced. Among them, the range of the preset temperature can be 39°C to 41°C, preferably 40.5°C.

[0065] That is to say, the adapter 50 or the electric field generator 70 can determine the detection coding array of the electrode plate 30 based on the AD sampling value, identify whether there are faults in multiple temperature detection units 34 in the electrode plate 30 according to the detection coding array, and execute corresponding reminder and protection strategies when there are faults; when there are faults, the number of temperature detection units 34 with faults can also be obtained based on the detection coding array, and it can be determined whether the electrode plate 30 needs to be replaced based on the number, and corresponding reminder and protection strategies are executed when the electrode plate 30 needs to be replaced; the temperature at each electrode plate unit 33 in the electrode plate 30 can also be obtained based on the AD sampling value, and it can be judged whether the electrode plate 30 is overheated according to the temperature, and corresponding reminder and protection strategies are executed when there is an overheating situation.

[0066] Optionally, the temperature sensor 341 in the temperature detection unit 34 is a thermistor. In this embodiment, the temperature sensor 341 is a negative temperature coefficient thermistor, and its characteristic is that the higher the temperature, the smaller the resistance value, and the lower the temperature, the larger the resistance value. Since the electrode plate 30 is attached to the human body surface during use, and the human body surface temperature is generally between 36°C and 37°C, a negative temperature coefficient thermistor with a temperature range of 0°C to 50°C can be selected. For example, a thermistor with the model NCP18XH103D03RB can be selected. When the temperature it senses is 0°C, the corresponding resistance value is about 27.45KΩ; when the sensed temperature is 25°C, the corresponding resistance value is about 10.0KΩ; when the sensed temperature is 50°C, the corresponding resistance value is about 4.16KΩ. In other embodiments, the temperature sensor 341 is a positive temperature coefficient thermistor.

[0067] Such as Figure 2 and Figure 4 As shown, when the controller 51 controls any one of the control switches in the switch unit 54 to conduct and the remaining control switches to disconnect, the DC power supply VCC provides direct current for the voltage dividing resistor Rz, 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 dividing resistor Rz through the corresponding acquisition channel, that is, the voltage divided by the temperature sensor 341, the diode 342, and the voltage dividing resistor Rz, to obtain the AD sampling value, that is, the voltage value, as shown in the following formula (1):

[0068] VADC = (VCC - VD) × R / (R1 + R) (1)

[0069] Wherein, VADC is the AD sampling value, that is, the voltage value, VCC is also used to represent the voltage magnitude of the DC power supply, VD is the voltage drop of the diode 342, R is the resistance value of the temperature sensor 341 (thermistor), and R1 is also used to represent the resistance value of the voltage dividing resistor Rz.

[0070] Assume that the voltage drop VD of the diode 342 is 0.3V and the resistance value R1 of the voltage-dividing resistor Rz is 10KΩ. Then, when the temperature sensed by the temperature sensor 341 (thermistor) is 0°C, the corresponding resistance value 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 the temperature sensor 341 (thermistor) is 25°C, the corresponding resistance value 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 the temperature sensor 341 (thermistor) is 50°C, the corresponding resistance value 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 the temperature sensor 341 (thermistor) is disconnected, for example, the temperature sensor 341 (thermistor) is not soldered or the temperature sensor 341 (thermistor) is open-circuited, the corresponding AD sampling value can be obtained as 3.3V. When the temperature sensor 341 (thermistor) and the diode 342 are short-circuited, the corresponding AD sampling value can be obtained as 0V.

[0071] Since the ADC sampling unit 52 samples the voltage value of the temperature sensor 341 (thermistor), and different temperatures sensed by the temperature sensor 341 (thermistor) have corresponding different voltage values, the voltage values sampled 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, that is, different voltage intervals where the voltage value is located correspond to different codes. Based on this code, the detection code array of the electrode plate 30 can be determined. The detection code array includes at least one of the first code, the second code, and the third code. Among them, the first code is used to indicate that the temperature detection unit 34 is in a normal state, the second code is used to indicate that the temperature detection unit 34 is in an open-circuit state or not set state, and the third code is used to indicate that the temperature detection unit 34 is in a short-circuit state.

[0072] In this embodiment, taking the temperature sensor 341 sensing the temperature in the range of 0°C to 50°C and the range of the AD sampling value (i.e., the voltage value) sampled by the ADC sampling unit 52 being 0.88V to 2.20V as an example, considering factors such as detection errors, the range of the voltage value can be appropriately enlarged to 0.5V to 3V.

[0073] When the AD sampling value obtained by the ADC sampling unit 52 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 sampling unit 52 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 sampling unit 52 is greater than or equal to 3.1V, the corresponding code is the second code such as 2. Therefore, among the corresponding detection positions with numbers 1 to 20 of the electrode patch 30, the temperature sensor 341 is short-circuited, and the corresponding code is the third code such as 0; the temperature sensor 341 is normal, and the corresponding code is the first code such as 1; there is no temperature sensor 341 or the temperature sensor 341 is open-circuited, and the corresponding code is the second code such as 2.

[0074] Reference Figure 2 As shown, under normal circumstances, when the electrode patch 30 has 20 electrode patch units 33, and each electrode patch unit 33 includes a temperature sensor 341 and a diode 342, that is, the corresponding detection positions with numbers 1 to 20 of the electrode patch 30 all have a temperature sensor 341, and the codes are all 1. Combining the 20 codes, a 20-bit code array 1111111111 11111 11111 is obtained. When the temperature sensor 341 is open-circuited, assuming that the temperature sensor 341 at the detection position numbered 1 is open-circuited, then the obtained 20-bit code array is 21111 11111 11111 11111. When the temperature sensor 341 is short-circuited, assuming that the temperature sensor 341 at the detection position numbered 1 is short-circuited, then the obtained 20-bit code array is 01111 11111 11111 11111.

[0075] Based on the above coding principle, the quality of the electrode patch 30 can be monitored during use, so that the user can replace the electrode patch 30 in time to avoid low-temperature burns. The specific process is as follows:

[0076] Step 1: Provide at least a pair of qualified electrode patches 30 (since the electrode patch 30 is a medical device, each electrode patch 30 will undergo various tests before leaving the factory to ensure that the electrode patch 30 is qualified. Therefore, the electrode patches 30 provided to the user are all qualified electrode patches 30). Connect at least a pair of qualified electrode patches 30 to the aforementioned adapter 50, and connect the aforementioned adapter 50 to the aforementioned electric field generator 70.

[0077] Step 2: Power on the electric field generator 70 to provide a DC power supply VCC for the temperature detection unit 34 in at least one pair of qualified electrode plates 30 for temperature detection. The ADC sampling unit 52 in the adapter 50 samples the analog temperature signals detected by the temperature detection unit 34 of at least one pair of qualified electrode plates 30 to obtain a number of AD sampling values. The controller 51 in the adapter 50 obtains at least two groups of standard coding arrays A1, A2 according to the foregoing coding rules. The at least two groups of standard coding arrays A1, A2 can be stored in the adapter 50 and used as comparison codes.

[0078] Step 3: Turn off the power of the electric field generator 70, and arrange the foregoing at least one pair of qualified electrode plates 30 on the corresponding body surface of the patient's tumor part.

[0079] Step 4: Power on the electric field generator 70 to provide a DC power supply VCC for the temperature detection unit 34 in at least one pair of qualified electrode plates 30 for temperature detection, and at the same time provide an alternating electric signal for the electrode plate unit 33 in the electrode plates 30 to form an alternating electric field between the paired electrode plates 30 for tumor electric field treatment. The ADC sampling unit 52 in the adapter 50 samples the temperature signals detected by the temperature detection unit 34 of at least one pair of qualified electrode plates 30 to obtain a number of AD sampling values. The controller 51 in the adapter 50 obtains at least two groups of detection coding arrays B1’, B2’ according to the foregoing coding rules.

[0080] Step 5: The controller 51 in the adapter 50 compares and judges the detection coding arrays B1’, B2’ with the corresponding standard coding arrays A1, A2 one by one. If the detection coding arrays B1’, B2’ are consistent with the standard coding arrays A1, A2, then loop through Step 4 and Step 5; if there is at least one detection coding array B1’ or B2’ that is inconsistent with the standard coding arrays A1, A2, then go to Step 6.

[0081] Step 6: The adapter 50 confirms the number of abnormal temperature detection units 34 in the electrode plates 30 corresponding to the inconsistent detection coding arrays B1’ or / and B2’, and judges whether the number of abnormal temperature detection units 34 in the corresponding electrode plates 30 exceeds the upper limit. If it does not exceed the upper limit, then go to Step 7; if it exceeds the upper limit, then go to Step 8.

[0082] Step 7: Continue to loop through Step 4 and Step 5.

[0083] Step 8: The adapter 50 issues an alarm by controlling its internal reminder unit (not shown), and at the same time sends a corresponding signal to the electric field generator 70 through the serial communication unit 56, so that the electric field generator 70 stops providing an alternating electric signal for the electrode plate unit 33 in the electrode plates 30, reminding the user to replace the corresponding electrode plates 30.

[0084] Step 9: Turn off the power supply of the electric field generator 70, remove the electrode plate 30 to be replaced from the adapter 50, and connect the new electrode plate 30 to the adapter 50.

[0085] Step 10: Power on the electric field generator 70, and continue to provide DC power VCC to the temperature detection unit 34 in the electrode plate 30 connected to the adapter 50 for temperature detection. The ADC sampling unit 52 in the adapter 50 samples the temperature signal detected by the temperature detection unit 34 of the qualified replaced electrode plate 30 to obtain a number of AD sampling values. The controller 51 in the adapter 50 obtains a new standard coding array A1' or / and A2' according to the foregoing coding rules, and compares at least one new standard coding array A1' or / and A2' with the corresponding stored standard coding array A1 or / and A2. If the new standard coding array A1' or / and A2' is consistent with the standard coding array A1 or / and A2, turn off the power supply of the electric field generator 70, configure the new replaced electrode plate 30 on the corresponding body surface of the patient's tumor part, and then loop through Steps 4 and 5; if after comparing the new standard coding array A1' or / and A2' with the foregoing stored standard coding A1 or / and A2 one by one, there is at least one new standard coding array A1' and / or A2' that is inconsistent with the foregoing stored and corresponding standard coding array A1 and / or A2, loop through Step 9 and Step 10 until the new standard coding array A1' and / or A2' of the qualified replaced electrode plate 30 is consistent with the foregoing stored and corresponding standard coding array A1 and / or A2.

[0086] It should be noted that in the above steps, the paired electrode plates 30 can use electrode plates 30 with the same design, that is, the standard coding arrays of the paired electrode plates 30 are the same, that is, the standard coding arrays A1 and A2 are the same.

[0087] The above Steps 1 and 2 can be replaced by the user inputting at least two groups of standard coding arrays A1, A2, and the at least two groups of standard coding arrays A1, A2 can be stored in the adapter 50 and used as comparison codes.

[0088] In the above Step 6, the number of abnormal temperature detection units 34 in the corresponding electrode plate 30 is determined by the number of codes with differences in the comparison of the inconsistent detection coding array A1' and / or A2' with the corresponding standard coding arrays A1, A2. For example, when A1' is compared with A1 and only the first code is different, the number of abnormal temperature detection units 34 in the corresponding electrode plate 30 is 1; another example is that when A1' is compared with A1 and only the last two codes are different, the number of abnormal temperature detection units 34 in the corresponding electrode plate 30 is 2; and so on.

[0089] In the above step six, the upper limit can be set to 1, that is, when there is an abnormality in one temperature detection unit 34 on the electrode plate 30, step eight of alarming and replacing the electrode plate 30 is performed. In other embodiments, in the above step six, the upper limit is not limited to 1, and can also be a positive integer close to the proportional number of the temperature detection units 34 of the electrode plate 30.

[0090] In the above step eight, the reminder unit (not shown) may include at least two indicator lights (not shown) corresponding one-to-one to the electrode plates 30, indicating the state of a corresponding electrode plate 30. When there is no need to replace the electrode plate 30, the indicator lights (not shown) all turn green; when the electrode plate 30 needs to be replaced, the indicator light (not shown) corresponding to the electrode plate 30 to be replaced turns red. The state of the electrode plate 30 not needing to be replaced or needing to be replaced can also be indicated by the indicator light (not shown) staying on or flashing.

[0091] In the above step eight, the reminder unit (not shown) may further include a buzzer (not shown), indicating the state of the electrode plate 30, and reminding the user simultaneously with the alarm of the indicator light (not shown). When there is no need to replace the electrode plate 30, the buzzer (not shown) does not give an audible alarm; when the electrode plate 30 needs to be replaced, the buzzer (not shown) gives an audible alarm.

[0092] While comparing the detection coding array with the standard coding array in the above steps four, five, and six, temperature monitoring is also carried out simultaneously. The steps are as follows:

[0093] Step eleven: The controller 51 in the adapter 50 calculates the digital temperature signal detected by the temperature detection unit 34 based on a number of AD sampling values, and determines whether the digital temperature signal exceeds a preset temperature. If there is a digital temperature signal detected by the temperature detection unit 34 of the electrode plate 30 that exceeds the preset temperature, step twelve is performed; if the digital temperature signals detected by the temperature detection units 34 of the electrode plate 30 are all below the preset temperature, step eleven is continued.

[0094] Step twelve: When the controller 51 in the adapter 50 detects that the temperature detected by the temperature detection unit 34 of the electrode plate 30 exceeds the preset temperature, it sends a corresponding signal through the serial communication unit 56, so that the electric field generator 70 reduces or turns off the alternating electric signal of a corresponding pair of electrode plates 30 until the temperature detected by the temperature detection unit 34 of the corresponding electrode plate 30 is below the preset temperature. Among them, the range of the preset temperature can be 39°C to 41°C, preferably 40.5°C.

[0095] It should be noted that the above process takes the quality monitoring of the electrode sheet 30 by the adapter 50 as an example for illustration. The quality monitoring of the electrode sheet 30 can also be performed by the electric field generator 70, or the adapter 50 and the electric field generator 70 can respectively perform partial quality monitoring. Details are not elaborated here. In addition, the number of the above electrode sheets 30, the number of electrode sheet units 33 of each electrode sheet 30, the setting of the sampling code, etc. are all exemplary illustrations and do not limit the present application.

[0096] In the above embodiment, the adapter 50 samples the analog temperature signals detected by each temperature detection unit 34 in the electrode sheet 30, and the adapter 50 or the electric field generator 70 determines the detection code array of the electrode sheet 30 according to the sampled analog temperature signals detected by each temperature detection unit 34, and compares the detection code array with the preset standard code array to identify the fault conditions of each temperature detection unit 34 in the electrode sheet 30 and the number of temperature detection units 34 with faults, and then determines whether the electrode sheet 30 needs to be replaced based on the number, so as to be able to monitor whether the electrode sheet 30 is damaged during use, so that the user can replace the electrode sheet 30 in time to avoid or reduce the risk of low-temperature scalding of the patient; it is also possible to determine whether the electrode sheet 30 has an over-temperature condition according to the sampled analog temperature signals detected by each temperature detection unit 34 by the adapter 30 or the electric field generator 70 to avoid low-temperature scalding of the patient.

[0097] The present invention also provides an electrode sheet fault detection method, which is applied to the foregoing tumor electric field treatment system. Refer to Figure 5 As shown, the method includes:

[0098] S91, obtaining the analog temperature signals detected by each temperature detection unit 34 in the electrode sheet 30.

[0099] S92, determining the detection code array of the electrode sheet 30 according to the analog temperature signals detected by each temperature detection unit 34.

[0100] As an implementation manner, the analog temperature signal is characterized by a voltage value. Determining the detection code array of the electrode sheet 30 according to the analog temperature signals detected by each temperature detection unit 34 includes: determining the voltage range where the voltage value is located; determining the code corresponding to the corresponding temperature detection unit according to the voltage range where the voltage value is located, wherein different voltage ranges where the voltage value is located correspond to different codes; generating the detection code array of the corresponding electrode sheet 30 according to the codes corresponding to each temperature detection unit 34. For example, the detection 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 is in a normal state, the second code is used to indicate that the temperature detection unit is in an open circuit state or an unset state, and the third code is used to indicate that the temperature detection unit is in a short circuit state.

[0101] S93. Compare the detected coding array with the preset standard coding array to identify the fault conditions of each temperature detection unit 34 in the electrode patch 30.

[0102] Further, when a faulty temperature detection unit 34 in the electrode patch 30 is identified, the method further includes: controlling the tumor electric field therapy system 1000 to send out a first reminder message, and controlling the electric field generator 70 to continue working.

[0103] Optionally, after comparing the detected coding array with the preset standard coding array, the method further includes: determining the number of faulty temperature detection units 34 in the electrode patch 30; judging whether the electrode patch 30 needs to be replaced according to the number. Further, when it is judged that the electrode patch 30 needs to be replaced, the method further includes: controlling the tumor electric field therapy system 1000 to send out a second reminder message, and controlling the electric field generator 70 to stop working.

[0104] Optionally, before comparing the detected coding array with the preset standard coding array, the method further includes: when the qualified electrode patch 30 is connected to the electric field generator 70 through the adapter 50, controlling the electric field generator 70 to work, and determining the preset standard coding array according to the analog temperature signals detected by each current temperature detection unit 34.

[0105] Optionally, after obtaining the analog temperature signals detected by each temperature detection unit 34 in the electrode patch 30, the method further includes: determining the temperature at the corresponding electrode patch unit 33 according to the analog temperature signals detected by each temperature detection unit 34; when it is identified that the electrode patch 30 has an over-temperature condition according to the temperature at the corresponding electrode patch unit 33, controlling the electric field generator 70 to reduce the amplitude of the alternating electric signal or stop outputting the alternating electric signal.

[0106] It should be noted that for the description of the electrode patch fault detection method, please refer to the foregoing description of the tumor electric field therapy system 1000, which will not be elaborated here.

[0107] In the above embodiments, by sampling the analog temperature signals detected by each temperature detection unit 34 in the electrode sheet 30, determining the detection coding array of the electrode sheet 30 according to the sampled analog temperature signals detected by each temperature detection unit 34, and comparing the detection coding array with a preset standard coding array, the fault conditions of each temperature detection unit 34 in the electrode sheet 30 and the number of temperature detection units 34 with faults are identified. Furthermore, based on the number, it is determined whether the electrode sheet 30 needs to be replaced, so that it is possible to monitor whether the electrode sheet 30 is damaged during use, facilitating the user to replace the electrode sheet 30 in a timely manner, avoiding or reducing the risk of low-temperature scalding of the patient; it is also possible to determine whether there is an over-temperature condition in the electrode sheet 30 based on the temperature signals detected by each temperature detection unit 34 sampled, so as to avoid low-temperature scalding of the patient.
