Referring to fig. 2-3, the adapter 50 includes a main control board electrically connected to the first connector 40, and 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 (e.g., control switches K1, K2, K3 and K4), and a serial communication unit 56. The controller 51 is configured to configure the switching states of a plurality of control switches of a plurality of switching units 54.

The ADC sampling unit 52 is connected to the controller 51, and the ADC sampling unit 52 is configured to sample the analog temperature signal detected by each temperature detecting unit 34, to obtain a plurality of AD sampling values. As shown in fig. 2, the ADC sampling unit 52 samples the analog temperature signal detected by the corresponding temperature detecting unit 34 in each row group at the same time by using the corresponding temperature sampling points, so as to obtain a plurality of AD sampling values. Specifically, the ADC sampling unit 52 has a plurality of acquisition channels, and the number of the acquisition channels is equal to or greater than the number of the column groups. In this embodiment, 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 temperature signal is characterized by the voltage value.

The controller 51 is used to configure the switching state of the control switch. 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 collect the analog temperature signals detected by the set of temperature detecting units 34 shorted to the turned-on control switch. For example, the ground terminals (not numbered) of the temperature detection units 34 numbered 1, 2, 3, 4, 5 are shorted together and connected to the ground pin GND through the control switch K1 in the switch unit 54 within the adapter 50, and the signal terminals (not numbered) of the temperature detection units 34 numbered 1, 2, 3, 4, 5 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 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.

When the ADC sampling unit 52 obtains a plurality of AD sampling values, it sends the plurality of AD sampling values to the controller 51, so that the controller 51 determines a detection code array of the electrode slice 30 according to the plurality of AD sampling values, and compares the detection code array with a preset standard code array to identify a fault condition of each temperature detecting unit 34 in the electrode slice 30. In the present embodiment, the controller 51 can selectively cause any one row group temperature detection unit 34 of the 20 temperature detection units 34 to detect temperature by selectively controlling on and off of any one of four control switches of the switch unit 54. The ADC sampling unit 52 collects the analog temperature signals detected by the set of temperature detecting units 34 through the corresponding temperature sampling points at the same time to obtain a plurality of AD sampling values, and transmits the AD sampling values to the controller 51, and the controller 51 determines a detection code array of the electrode slice 30 according to the plurality of AD sampling values, compares the detection code array with a preset standard code array, and identifies a fault condition of each temperature detecting unit 34 in the electrode slice 30.

The adapter 50 further includes a reminding unit (not shown), where the reminding unit (not shown) is connected to the controller 51, and when the temperature detecting unit 34 of the electrode plate 30 has a fault, the controller 51 controls the reminding unit (not shown) to send out a first reminding message and instructs the electric field generator 70 to keep working. For example, the controller 51 controls the reminding unit (not shown) to be lighted green as an indicator light when the temperature detecting unit 34 of the failure does not exist in the electrode sheet 30, and controls the reminding unit (not shown) to be lighted red as an indicator light when the temperature detecting unit 4 of the failure exists in the electrode sheet 30.

The controller 51 also determines the number of the temperature detecting units 34 having the fault in the electrode sheet 30 when comparing the detecting code array with the preset standard code array, and determines whether the electrode sheet 30 needs to be replaced according to the number. For example, when the number exceeds a preset number (the minimum may be set to 1), it is judged that the electrode sheet 30 needs to be replaced, and when the number does not exceed the preset number, it is judged that the electrode sheet 30 does not need to be replaced. The controller 51 may also control the reminding unit (not shown) to send out the second reminding information and instruct the electric field generator 70 to stop working when it is determined that the electrode sheet 30 needs to be replaced. For example, when the controller 51 determines that the electrode pad 30 needs to be replaced, it controls the reminding unit (not shown) to turn on red and flash as an indicator light, and at the same time, it may control the reminding unit (not shown) to alarm as a buzzer, and at the same time, it may 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.

During the tumor electric field treatment of the electrode sheet 30, the adapter 50 periodically performs the aforementioned failure detection of the electrode sheet 30, and timely replaces the electrode sheet 30. The adapter 50 obtains a plurality of AD sampling values according to the sampled analog temperature signal detected by each of the temperature detecting units 34, and transmits the AD sampling values to the controller 51, and the controller 51 converts the plurality of AD sampling values to obtain a digital temperature signal according to the plurality of AD sampling values to determine the temperature at the corresponding electrode pad unit 33, in addition to periodically performing the aforementioned fault detection of the electrode pad 30. The controller 51 transmits the digital temperature signal to the electric field generator 70 through the serial communication unit 56, and the electric field generator 70 reduces the amplitude of the alternating electric signal or stops outputting the alternating electric signal when the electric field generator 70 recognizes that the electrode sheet 30 has an over-temperature condition according to the temperature at the corresponding electrode sheet unit 33. In this embodiment, the controller 51 may calculate the temperature at each electrode plate unit 33 of the electrode plates 30 based on a plurality of AD sampling values, then compare the temperature with a preset temperature, and if the temperature exceeds the preset temperature, consider that the electrode plates 30 have an over-temperature condition, at this time, 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 or reduces the amplitude of the alternating electric signal. Wherein the preset temperature may be in the range of 39-41 ℃, preferably 40.5 ℃.

Referring to fig. 1, the adaptor 50 further includes a second cable 55 connected to the electric field generator 70. A second connector 60 is provided between the adaptor 50 and the electric field generator 70, the second connector 60 being adapted to connect the electric field generator 70 to the adaptor 50. The second connector 60 includes a second plug 61 provided at an end of the second cable 55 remote 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-on spring connectors, i.e. the second connector 60 connects the adaptor 50 with the electric field generator 70 by means of connectors. Referring to fig. 3, when the number of first connectors 40 is 4, each of the first connectors such as X1, Y1, X2 and Y2 is connected to the second connector 60 through an alternating power line, and the first connectors such as X1, Y1, X2 and Y2 also connect the switching unit 54 and the ADC sampling unit 52, respectively. The second connector 60 is connected with the serial port communication unit 56 through a receiving data line RX and a transmitting data line TX, the VCC pin of the second connector 60 is connected with the power supply end of the controller 51, the GND pin of the second connector 60 is grounded, and the VCC pin of the second connector 60 is also connected with the temperature sampling point through a corresponding voltage dividing resistor Rz.

In other embodiments, the controller 51 may also send a plurality 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 determines a detection code array of the electrode slice 30 according to the plurality of AD sampling values, and compares the detection code array with a preset standard code array to identify a fault condition of each temperature detection unit 34 in the electrode slice 30. The electric field generator 70 also issues a first warning message when there is a faulty temperature detection unit 34 in the electrode sheet 30, and continues to output an alternating electric signal. For example, the electric field generator 70 may include a warning unit (not shown), and the electric field generator 70 controls the warning unit (not shown) to be lighted green as an indicator light when the temperature detecting unit 34 of the fault does not exist in the electrode sheet 30, and controls the warning unit (not shown) to be lighted red as an indicator light when the temperature detecting unit 4 of the fault exists in the electrode sheet 30.

The electric field generator 70 also determines the number of the temperature detecting units 34 having the fault in the electrode sheet 30 when comparing the detecting code array with the preset standard code array, and judges whether the electrode sheet 30 needs to be replaced according to the number. For example, when the number exceeds the preset number, it is judged that the electrode sheet 30 needs to be replaced, and when the number does not exceed the preset number, it is judged that the electrode sheet 30 does not need to be replaced. The electric field generator 70 also sends out a second reminding message when the electrode plate 30 is judged to need to be replaced, and stops outputting the alternating electric signal. For example, when it is determined that the electrode sheet 30 needs to be replaced, the electric field generator 70 controls the reminding unit (not shown) such as an indicator lamp to turn on red and flash, and simultaneously controls the reminding unit (not shown) such as a buzzer to alarm, and simultaneously stops outputting the alternating electric signal.

The electric field generator 70 also determines the temperature at the corresponding electrode sheet unit 33 from the plurality of AD sampling values, and reduces the amplitude of the alternating electric signal or stops outputting the alternating electric signal when the electrode sheet 30 is identified as having an over-temperature condition based on the temperature at the corresponding electrode sheet unit 33. For example, the electric field generator 70 may calculate a temperature at each electrode sheet unit 33 of the electrode sheets 30 based on a plurality of AD sampling values, then compare the temperature with a preset temperature, and if the temperature exceeds the preset temperature, consider that the electrode sheets 30 have an over-temperature condition, and at this time, may stop outputting the alternating electric signal or reduce the amplitude of the alternating electric signal. Wherein the preset temperature may be in the range of 39-41 ℃, preferably 40.5 ℃.

That is, the detection code array of the electrode sheet 30 may be determined based on the AD sampling values by the adapter 50 or the electric field generator 70, and whether or not a fault condition exists in the plurality of temperature detection units 34 in the electrode sheet 30 is recognized according to the detection code array, and corresponding alerting and protecting strategies are performed when the fault condition exists; the number of the temperature detection units 34 with faults can be obtained based on the detection code array when the fault condition exists, whether the electrode plate 30 needs to be replaced or not is determined based on the number, and corresponding reminding and protection strategies are executed when the electrode plate 30 needs to be replaced; it is also possible to obtain the temperature at each electrode sheet unit 33 in the electrode sheet 30 based on the AD sampling value, and judge whether the electrode sheet 30 has an over-temperature condition according to the temperature, and execute corresponding reminding and protection strategies when the over-temperature condition exists.

Alternatively, the temperature sensor 341 in the temperature detecting unit 34 is a thermistor. In this embodiment, the temperature sensor 341 is a thermistor with a negative temperature coefficient, and is characterized in 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 ℃. In other embodiments, temperature sensor 341 is a positive temperature coefficient thermistor.

As shown in fig. 2 and fig. 4, when the controller 51 controls any one of the switch units 54 to turn on and the other switch units to turn off, the dc power supply VCC sequentially provides dc power to the voltage dividing resistor Rz, the temperature sensor 341 and the diode 342, and 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 collection channel, that is, the voltage division between the temperature sensor 341 and the diode 342 and the voltage dividing resistor Rz, to obtain an AD sampling value, that is, a voltage value, as shown in the following formula (1):

VADC＝(VCC-VD)×R/(R ₁ +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 the diode 342, R is the resistance value of the temperature sensor 341 (thermistor), R ₁ And also to represent the resistance of the divider resistor Rz.

Assume that the voltage drop VD of the diode 342 is 0.3V, and the resistance R of the divider resistor Rz ₁ When the temperature sensed by the temperature sensor 341 (thermistor) is 0 ℃, the corresponding resistance is about 27.45kΩ, and based on the formula (1), an 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 ℃, the corresponding resistance is about 10.0kΩ, and based on the 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 (thermistor) is 50 ℃, the corresponding resistance is about 4.16kΩ, and the corresponding AD sampling value v50= (3.3-0.3) ×4.16/(10+4.16) =0.88V can be obtained based on the formula (1). When the temperature sensor 341 (thermistor) is turned off, for example, the unwelded temperature sensor 341 (thermistor) or the temperature sensor 341 (thermistor) is turned off, the AD sampling value corresponding thereto can be 3.3V. When the temperature sensor 341 (thermistor) and the diode 342 are short-circuited, an AD sampling value corresponding thereto is 0V.

Since the voltage value of the temperature sensor 341 (thermistor) is collected by the ADC sampling unit 52, and the temperature sensor 341 (thermistor) detects different temperatures and has corresponding different voltage values, the voltage value collected by the ADC sampling unit 52 can be reasonably segmented to be distinguished, and meanwhile, the voltage value is converted into corresponding codes, that is, the voltage intervals where the voltage value is located are different, and the detection code array of the electrode slice 30 can be determined based on the codes. The detection code array includes at least one of a first code for indicating that the temperature detection unit 34 is in a normal state, a second code for indicating that the temperature detection unit 34 is in an off state or an unset state, and a third code for indicating that the temperature detection unit 34 is in a short state.

In the present embodiment, taking the temperature sensor 341 sensing the 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 properly amplified to 0.5V to 3V in consideration of the detection error factor and the like.

When the AD sampling value obtained by sampling by the ADC sampling unit 52 is greater than 0.5V and less than 3V, the corresponding code is a first code such as 1; when the AD sampling value obtained by sampling by the ADC sampling unit 52 is equal to or less than 0.3V, the corresponding code is a third code such as 0; when the AD sampling value obtained by sampling by the ADC sampling unit 52 is 3.1V or more, the corresponding code is a second code such as 2. Therefore, in the corresponding detection positions numbered 1 to 20 of the electrode pad 30, the temperature sensor 341 is shorted, and the corresponding code is a third code such as 0; the temperature sensor 341 is normal, and the corresponding code is a first code such as 1; there is no temperature sensor 341 or temperature sensor 341 is off, the corresponding code is a second code such as 2.

Referring to fig. 2, normally, when the electrode pad 30 has 20 electrode pad units 33, each electrode pad unit 33 includes one temperature sensor 341 and one diode 342, that is, the corresponding detection bits numbered 1 to 20 of the electrode pad 30 have the temperature sensor 341 and the codes are all 1, the 20 codes are combined to obtain a 20-bit code array 11111 11111 11111 11111. When the temperature sensor 341 is disconnected, assuming that the temperature sensor 341 of the detection bit 1 is disconnected, the obtained 20-bit code array is 21111 11111 11111 11111. When the temperature sensor 341 is shorted, assuming that the temperature sensor 341 of the detection bit 1 is shorted, the obtained 20-bit code array is 01111 11111 11111 11111.

Based on the above coding principle, the quality of the electrode plate 30 can be monitored in the use process, so that a user can replace the electrode plate 30 in time, and low-temperature scalding is avoided, and the specific process is as follows:

step one: at least one pair of acceptable electrode pads 30 is provided (since the electrode pads 30 are medical devices, each electrode pad 30 is subjected to multiple tests before shipment to ensure that the electrode pad 30 is acceptable, and therefore the electrode pads 30 provided to the hands of the user are all acceptable electrode pads 30). At least one pair of acceptable electrode pads 30 is connected to the adaptor 50, and the adaptor 50 is connected to the electric field generator 70.

Step two: the electric field generator 70 is energized to provide a dc power source VCC to the temperature sensing unit 34 in at least one pair of acceptable electrode pads 30 for temperature sensing. The ADC sampling unit 52 in the adapter 50 collects the analog temperature signals detected by the temperature detecting unit 34 of at least one pair of qualified electrode plates 30, and obtains a plurality of AD sampling values, and the controller 51 in the adapter 50 obtains at least two sets of standard coding arrays A1, A2 according to the foregoing coding rule, where the at least two sets of standard coding arrays A1, A2 may be stored in the adapter 50 and used as a comparison code.

Step three: the electric field generator 70 is turned off and the at least one pair of acceptable electrode pads 30 are disposed on the corresponding body surface of the patient's tumor portion.

Step four: the electric field generator 70 is energized to provide a direct current power supply VCC to the temperature detection unit 34 in at least one pair of acceptable electrode pads 30 for temperature detection, while an alternating electrical signal is provided to the electrode pad units 33 in the electrode pads 30 to form an alternating electric field between the pair of electrode pads 30 for tumor electric field therapy. The ADC sampling unit 52 in the adapter 50 collects the temperature signals detected by the temperature detecting unit 34 of at least one pair of qualified electrode plates 30 to obtain a plurality of AD sampling values, and the controller 51 in the adapter 50 obtains at least two sets of detection code arrays B1', B2' according to the foregoing coding rule.

Step five: the controller 51 in the adapter 50 compares the detection code arrays B1', B2' with the corresponding standard code arrays A1, A2 one by one, and if the detection code arrays B1', B2' are consistent with the standard code arrays A1, A2, the steps four and five are performed in a circulating manner; if at least one of the detection code arrays B1 'or B2' is inconsistent with the standard code arrays A1, A2, step six is performed.

Step six: the adapter 50 confirms the number of abnormal temperature detection units 34 in the electrode plate 30 corresponding to the non-uniform detection coding array B1 'or/and B2', and judges whether the number of abnormal temperature detection units 34 in the corresponding electrode plate 30 exceeds the upper limit, if not, step seven is performed; if the upper limit is exceeded, step eight is performed.

Step seven: and continuing to circularly carry out the step four and the step five.

Step eight: the adaptor 50 gives an alarm by controlling a reminding unit (not shown) inside thereof, and simultaneously gives a corresponding signal to the electric field generator 70 through the serial communication unit 56, so that the electric field generator 70 stops supplying the alternating electric signal to the electrode pad unit 33 in the electrode pad 30, reminding the user of replacing the corresponding electrode pad 30.

Step nine: the electric field generator 70 is powered off, the electrode sheet 30 that needs replacement is removed from the adapter 50, and a new electrode sheet 30 is attached to the adapter 50.

Step ten: the electric field generator 70 is energized to continue to supply the direct current power VCC to the temperature detection unit 34 in the electrode pad 30 connected to the adapter 50 for temperature detection. The ADC sampling unit 52 in the adapter 50 collects the temperature signal detected by the temperature detecting unit 34 of the qualified electrode plate 30 on replacement to obtain a plurality of AD sampling values, the controller 51 in the adapter 50 obtains a new standard coding array A1 'or/and A2' according to the coding rule, at least one group of new standard coding arrays A1 'or/and A2' corresponding to the stored standard coding arrays A1 or/and A2 is compared, if the new standard coding arrays A1 'or/and A2' are consistent with the standard coding arrays A1 or/and A2, the power supply of the electric field generator 70 is turned off, the replaced new electrode plate 30 is configured on the corresponding body surface of the tumor part of the patient, and then the fourth and fifth steps are circulated; if there is at least one new set of standard code arrays A1 'and/or A2' inconsistent with the stored and corresponding standard code arrays A1 and/or A2 after the new standard code arrays A1 'and/or A2' are compared with the stored standard code arrays A1 and/or A2 one by one, step nine and step ten are looped until the new standard code arrays A1 'and/or A2' of the replaced qualified electrode plate 30 are consistent with the stored and corresponding standard code arrays A1 and/or A2.

It should be noted that, in the above steps, the electrode plates 30 of the same design may be used for the paired electrode plates 30, i.e., the standard code arrays of the paired electrode plates 30 are the same, i.e., the standard code arrays A1 and A2 are the same.

The first and second steps may be replaced by inputting at least two sets of standard code arrays A1 and A2 by the user, and the at least two sets of standard code arrays A1 and A2 may be stored in the adapter 50 and used as the comparison codes.

In the above step six, the number of abnormal temperature detecting units 34 in the corresponding electrode plate 30 is determined by the number of codes having differences in comparing the non-uniform detecting code arrays A1' and/or A2' with the corresponding standard code arrays A1, A2, for example, comparing A1' with A1, and if only the first code has differences, the number of abnormal temperature detecting units 34 in the corresponding electrode plate 30 is 1; for another example, when A1' is compared with A1, only the last two codes have a difference, the number of abnormal temperature detection units 34 in the corresponding electrode plate 30 is 2; etc.

In the above step six, the upper limit may be set to 1, that is, there is an abnormality in one temperature detecting unit 34 on the electrode sheet 30, that is, the step eight is performed to alarm and replace the electrode sheet 30. In other embodiments, in the above step six, the upper limit is not limited to 1, but may be a positive integer which is close to the number of the temperature detecting units 34 of the electrode sheet 30 in proportion thereto.

In the eighth step, the reminding unit (not shown) may include at least two indicator lamps (not shown) corresponding to the electrode pads 30 one by one, so as to indicate the state of the corresponding electrode pad 30. When the electrode sheet 30 does not need to be replaced, an indicator lamp (not shown) is lighted with a green light; when the electrode sheet 30 needs to be replaced, an indicator lamp (not shown) corresponding to the electrode sheet 30 to be replaced is lighted with a red lamp. The state in which the electrode sheet 30 is not replaced or needs to be replaced may be indicated by a long light or a blinking light (not shown).

In the above-mentioned step eight, the reminding unit (not shown) may further include a buzzer (not shown) for indicating the state of the electrode sheet 30 and reminding the user together with the alarm of the indicator lamp (not shown). When the electrode sheet 30 does not need to be replaced, a buzzer (not shown) does not give an audible alarm; when the electrode sheet 30 needs to be replaced, a buzzer (not shown) sounds an alarm.

And the fourth, fifth and sixth steps are performed to detect the comparison between the code array and the standard code array, and simultaneously perform temperature monitoring, and the steps comprise the following steps:

step eleven: the controller 51 in the adapter 50 calculates a digital temperature signal detected by the temperature detecting unit 34 according to the plurality of AD sampling values, and determines whether the digital temperature signal exceeds a preset temperature, if the digital temperature signal detected by the temperature detecting unit 34 of the electrode sheet 30 exceeds the preset temperature, step twelve is performed; if the digital temperature signals detected by the temperature detecting unit 34 of the electrode sheet 30 are all below the preset temperature, the step eleven is continued.

Step twelve: when the controller 51 in the adapter 50 detects that the temperature detected by the temperature detecting unit 34 of the electrode sheet 30 exceeds the preset temperature, a corresponding signal is sent through the serial communication unit 56 so that the electric field generator 70 reduces or shuts off the alternating electric signal of the corresponding pair of electrode sheets 30 until the temperature detected by the temperature detecting unit 34 of the corresponding electrode sheet 30 is below the preset temperature. Wherein the preset temperature may be in the range of 39-41 ℃, preferably 40.5 ℃.
