Description

Electrode sheet, electrode sheet identification method, tumor electric field treatment system and treatment equipment

Technical Field

The invention relates to the technical field of medical equipment, in particular to an electrode slice, a tumor electric field treatment system and treatment equipment.

Background

Currently, tumor electric field therapy systems mainly include an electric field generator, an adapter electrically connected to the electric field generator, and a plurality of pairs of electrode plates electrically connected to the electric field generator through the adapter. The electric field generator transmits alternating electric signals for tumor electric field treatment to each electrode slice through the adapter, and then the alternating electric field is applied to the tumor part of the patient through the electrode slices to carry out tumor electric field treatment. Because the positions of the tumor are different, the electric field treatment positions of the tumor are different, and the intensity and coverage area of the electric field are also different, for example, when the position is the head, the coverage area of the electric field is not very large, and the two pairs of electrode plates with 9 electrode plate units can be used for covering; when the part is chest and abdomen, the electric field coverage area is larger than that of the head, and the number of required electrode slice units is larger than that of the head, for example, electrode slices with 13, 20 or other electrode slice units more than 9 are used.

When tumor electric field therapy is performed, heat is accumulated at the corresponding position where the electrode plates are applied to the skin when the electric field is applied to the patient, and in order to avoid skin low-temperature scalding, a temperature sensor is required to be arranged at each electrode plate unit to monitor the skin surface temperature at each electrode plate unit. According to the factors such as the position that the tumour distributes and the scope that tumour electric field treatment needs to cover consider, when carrying out tumour electric field treatment, there is the condition that needs two pairs of electrode slices that electrode slice unit quantity is different to make up and use, and corresponding the quantity of temperature sensor that the electrode slice of different electrode slice unit quantity corresponds also is different, for example, the electrode slice that has 9 electrode slice units, 13 electrode slice units, the quantity of temperature sensor of the electrode slice of 20 electrode slice units is different, and the adapter needs to correspond 9 temperature sensor, 13 temperature sensor, 20 temperature sensor's analog temperature signal of gathering.

In the related art, the adapter collects the analog temperature signal of the temperature sensor on the electrode sheet connected thereto by the same collection procedure, but there are cases where the analog temperature signal is disturbed or a part of the temperature sensor cannot be collected. For example, if the adaptor collects the 20 temperature sensors of the pair of electrode plates having 20 electrode plate units according to the collection procedure of collecting the 20 temperature sensors to obtain 40 analog temperature signals, and if the adaptor collects the temperature sensors on the pair of electrode plates having 13 electrode plate units connected with the adaptor by the same collection procedure, 40 analog temperature signals are collected, only 26 analog temperature signals in the 40 analog temperature signals are analog temperature signals of the temperature sensors on the pair of electrode plates having 13 electrode plate units, and the other 4 analog temperature signals are interference signals, but the adaptor cannot identify which analog temperature signals are required analog temperature signals. If the adapter collects a pair of electrode sheets with 13 electrode sheet units and a pair of electrode sheets with 20 electrode sheet units connected according to a collection program for collecting 13 temperature sensors, all the temperature sensors on the electrode sheets with 13 electrode sheet units can be collected by the adapter, but 7 temperature sensors in the electrode sheets with 20 electrode sheet units cannot be collected by the adapter.

Since the plurality of temperature detecting units 34 are disposed in one-to-one correspondence with the plurality of electrode sheet units 33, the plurality of temperature detecting units 34 are also arranged in four rows and five columns on the circuit connection.

The ADC sampling unit 52 has a plurality of acquisition channels, and the number of acquisition channels is equal to or greater than the number of column groups. In this embodiment, as shown in fig. 5, the ADC sampling unit 52 has five sampling channels 1, 2, 3, 4 and 5, and each sampling channel only collects the analog temperature signal detected by a corresponding one of the temperature detecting units 34 at the same time to obtain an AD sampling value, where the AD sampling value is a voltage value, that is, the analog temperature signal is a voltage value. Four of the control switches in the switch unit 54 are turned on at the same time, and the other three control switches are turned off, so that the ADC sampling unit 52 can collect the analog temperature signals detected by the set of temperature detecting units 34 shorted to the turned-on control switches. Specifically, as shown in fig. 5, the grounding ends (not numbered) of the temperature detection units 34 with the numbers 1, 2, 3, 4 and 5 are shorted together, and are connected to the grounding pin GND through the control switch K1 in the switch unit 54 in the adapter 50, and the signal ends (not numbered) of the temperature detection units 34 with the numbers 1, 2, 3, 4 and 5 are respectively connected to the acquisition channels 1-5 of the ADC sampling unit 52 through corresponding temperature sampling points; the ground terminals (not numbered) of the temperature detection units 34 numbered 6, 7, 8, 9, 10 are shorted together and connected to the ground pin GND through the control switch K2 in the switch unit 54 within the adapter 50, and the signal terminals (not numbered) of the temperature detection units 34 numbered 6, 7, 8, 9, 10 are connected to the acquisition channels 1-5 of the ADC sampling unit 52 through the corresponding temperature sampling points, respectively; the ground terminals (not numbered) of the temperature detection units 34 numbered 11, 12, 13, 14, 15 are shorted together and connected to the ground pin GND through the control switch K3 in the switch unit 54 within the adapter 50, and the signal terminals (not numbered) of the temperature detection units 34 numbered 11, 12, 13, 14, 15 are connected to the acquisition channels 1-5 of the ADC sampling unit 52 through the corresponding temperature sampling points, respectively; the ground terminals (not numbered) of the temperature detecting units 34 numbered 16, 17, 18, 19, 20 are shorted together and connected to the ground pin GND through the control switch K4 in the switching unit 54 within the adapter 50, and the signal terminals (not numbered) of the temperature detecting units 34 numbered 16, 17, 18, 19, 20 are connected to the acquisition channels 1-5 of the ADC sampling unit 52 through the corresponding temperature sampling points, respectively. Meanwhile, each temperature sampling point is connected to the direct current power supply VCC via a corresponding voltage dividing resistor 53 within the adapter 50.

Alternatively, the temperature sensor 341 in the temperature detecting unit 34 is a thermistor, for example, the temperature sensor 341 is a negative temperature coefficient thermistor, and the characteristic is that the higher the temperature, the smaller the resistance, the lower the temperature, and the larger the resistance. The electrode sheet 30 is applied to the body surface of a human body when in use, and the body surface temperature is generally 36-37 ℃, so that a thermistor with a negative temperature coefficient in a temperature range of 0-50 ℃ can be selected. For example, a thermistor model NCP18XH103D03RB can be selected, which senses a temperature of 0℃ and has a corresponding resistance of about 27.45KΩ; the corresponding resistance is about 10.0KΩ at a sensed temperature of 25deg.C; the corresponding resistance was about 4.16kΩ at a temperature of 50 ℃.

VADC＝(VCC-VD)×R/(Rz+R) (1)

Wherein VADC is the AD sampling value, namely the voltage value, VCC is also used for representing the voltage of the direct current power supply, VD is the voltage drop of a diode, R is the resistance value of a thermistor, and Rz is the resistance value of a divider resistor.

Assuming that the voltage drop VD of the diode is 0.3V and the resistance Rz of the voltage dividing resistor is 10kΩ, when the temperature sensed by the temperature sensor 341 is 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 sensed by the temperature sensor 341 is 25 ℃, the corresponding resistance is about 10.0kΩ, and based on formula (1), an 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 is 50 ℃, the corresponding resistance is about 4.16kΩ, and an AD sampling value v50= (3.3-0.3) ×4.16/(10+4.16) =0.88V corresponding thereto can be obtained based on the formula (1). When the temperature sensor 341 is disconnected, for example, the temperature sensor 341 is abnormal in welding or the temperature sensor 341 is open, the AD sampling value corresponding thereto may be 3.3V. When the temperature sensor 341 and the diode 342 are short-circuited, an AD sampling value corresponding thereto is 0V.

Since the voltage value of the temperature sensor 341 is collected by the ADC sampling unit 52, the temperature sensor 341 detects that different temperatures have corresponding different voltage values, so that the voltage value collected by the ADC sampling unit 52 can be reasonably segmented for distinction, and meanwhile, the voltage value is converted into a corresponding code to identify the type of the electrode slice 30, that is, the number of the electrode slice units 33 on the electrode slice 30.

Specifically, taking the temperature sensor 341 sensing a temperature in the range of 0 ℃ to 50 ℃, and the range of the voltage value, which is the AD sampling value sampled by the ADC sampling unit 52, being 0.88V to 2.20V as an example, the range of the voltage value can be appropriately amplified to 0.5V to 3V in consideration of detection error factors and the like.

When the AD sampling value obtained by sampling by the ADC sampling unit 52 is more than 0.5V and less than 3V, the corresponding acquisition code is 1; when the AD sampling value obtained by sampling 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 sampling by the ADC sampling unit 52 is 3.1V or more, the corresponding acquisition code is 2. Therefore, in the corresponding detection positions numbered 1 to 20 of the electrode pad 30, the temperature sensor 341 is short-circuited, and the corresponding code is 0; a corresponding code with temperature sensor 341 is 1; no temperature sensor 341 is present and the temperature sensor 341 is disconnected, the corresponding code is 2.

Referring to fig. 5, at the time of sampling, regardless of the type of electrode pad 30 (i.e., the number of electrode pad units 33 or temperature sensors 341 of the electrode pad 30 is any one of 20 or less), the ADC sampling unit 52 obtains 20 AD sampling values per acquisition, and after each acquisition is completed, a 20-bit code array is formed based on the 20 AD sampling values, each type of electrode pad 30 has a corresponding code array, and thus the type of electrode pad 30 can be automatically identified by the code array.

As shown in fig. 10, when the electrode sheet 30 has 19 electrode sheet units 33 and 19 temperature detecting units 34, the 19 electrode sheet units 33 and 19 temperature detecting units 34 are arranged in four rows and five columns on the circuit connection, and the 19 electrode sheet units 33 and 19 temperature detecting units 34 are sequentially arranged, a wire (not numbered) is shorted at a corresponding position along which the 19 temperature detecting units 34 extend, that is, a wire (not numbered) is arranged at a crossing position of the four rows and five columns on the circuit connection and is shorted with a grounding end (not numbered) of the temperature detecting units 34 of the same row, and is shorted with a signal end (not numbered) of the temperature detecting units 34 of the same column.

The above 21 number arrays are all different, so that the controller 51 can judge the type of the electrode sheet 30 connected to the adapter 50 or whether the electrode sheet 30 is connected through the code array in the case that the electrode sheet 30 is normal.

In the case of a type determination of the electrode sheet 30, the controller 51 also determines from the coding array whether a temperature detection failure has occurred in the respective electrode sheet 30, wherein the analog temperature signal detected by each of the sampled temperature detection units 34 is also used to characterize whether a temperature detection failure has occurred in the electrode sheet 30.
