Detailed ways

In order to make the purpose, technical solutions and advantages of the present application more clearly understood, the present application will be described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, but not to limit the present application.

1 and 2, an embodiment of the present application provides a zero heat-flux temperature probe 3, including a flexible heating body 1 and a temperature sensor 2;

The temperature sensor 2 is arranged on the flexible heating body 1;

The temperature sensor 2 is used to measure temperature;

The flexible heating body 1 is used to block the heat dissipation of the temperature measurement point corresponding to the temperature sensor 2 .

Preferably, the flexible heating body 1 includes a packaging material 11, a flexible thermal insulation body 12 and a temperature-controlled heating device;

The temperature control heating device is connected to the temperature sensor 2, and is used for performing a corresponding heating action according to the detection signal of the temperature sensor 2;

The temperature-controlled heating device includes a heating element 13, and the heating element 13 and the flexible thermal insulation body 12 are stacked and deployed;

The packaging material 11 completely wraps the flexible thermal insulation body 12 and the heating element 13;

The temperature sensor 2 is arranged on the outer surface of the flexible heating body 1 and is located on the same side as the heating element 13 .

In this embodiment, the temperature sensing probe 3 includes a flexible heating body 1 and a temperature sensor 2 , and the temperature sensor 2 is arranged on the flexible heating body 1 . The temperature sensor 2 is used to measure the temperature. When the temperature sensor 2 is used to measure the temperature measurement point (such as the surface of human skin), the flexible heating body 1 is pressed against the temperature measurement point. When there is a gap on the surface of the temperature measurement point due to the pulling disturbance of the user's movement, the flexible heating body 1 can automatically fill the gap due to the overall ductility and elasticity of the flexible heating body 1, thereby preventing the heat loss of the temperature measurement point.

Preferably, the flexible heating body 1 includes a packaging material 11, a flexible thermal insulation body 12 and a temperature-controlled heating device. The temperature-controlled heating device includes a heating element 13 , a temperature switch, a temperature relay and a power supply, and is connected to the temperature sensor 2 , and can perform a corresponding heating action according to the detection signal of the temperature sensor 2 , that is, the detected temperature measured by the temperature sensor 2 . Specifically, the temperature-controlled heating device is used to heat the flexible heating body 1 , and the temperature-controlled heating device needs to ensure that the first temperature of the flexible heating body 1 is kept consistent with the detected temperature measured by the temperature sensor 2 . When the temperature-controlled heating device detects that the first temperature of the object to be heated is lower than the detected temperature of the temperature sensor 2, the relay in the temperature-controlled heating device closes the circuit, and the heating element 13 starts to work and start heating. When the first temperature of the heated object rises to be consistent with the detected temperature, the temperature relay controls the temperature switch to turn off, thereby cutting off the connection between the heating element 13 and the power supply, and the temperature-controlled heating device stops heating. Since the temperature control heating device generates a temperature consistent with the measurement point in the direction of heat loss, it can block the heat loss of the measurement point, and at the same time, it will not actively generate heat to affect the temperature rise of the measurement point, which greatly increases the temperature so that the measurement point reaches External thermal impedance. After a certain period of time, the temperature of the flexible heating body 1 is consistent with the temperature detected by the temperature sensor 2, that is, the temperature of the measurement point. At this time, the temperature of the measurement point will be equivalent to the core body temperature deep under the human body, effectively increasing the body temperature. detection accuracy. Preferably, the heating element 13 and the flexible thermal insulation body 12 are arranged inside the flexible heating body 1, and the two are stacked and deployed therebetween. The packaging material 11 completely wraps the flexible thermal insulation body 12 and the heating element 13 to form a flexible heating body 1 with elastic deformation capability as a whole. Other components of the temperature-controlled heating device, such as temperature relays, temperature switches, etc., can be deployed inside the flexible heating body 1, or can be arranged outside the flexible heating body 1 (for example, arranged on the outer surface of the packaging material 11). Those skilled in the art Corresponding location deployment can be performed as required, which is not limited here. The temperature sensor 2 is disposed on the outer surface of the flexible heating body 1 , that is, mounted on the packaging material 11 , and the temperature sensor 2 and the heating element 13 are located on the same side of the flexible heating body 1 . When the temperature probe 3 is in use, the temperature sensor 2 is arranged at the human body measurement point, and the side of the flexible heating body 1 where the temperature sensor 2 is arranged is attached to the surface of the measurement point (ie, human skin). The flexible heating body 1 itself has good elasticity and ductility. After the whole is compressed (for example, the temperature sensing probe 3 is clamped under the armpit), a certain deformation will occur, and the flexible heating body 1 will fill the gap between the human skin. . Even after the temperature sensing probe 3 is deployed, the user's limb movements cause the human tissues to pull and disturb each other, and the flatness of the surface of the measurement point changes. The deformation corresponding to the surface of the measurement point, so that the side of the flexible heating body 1 on which the temperature sensor 2 is deployed can be in complete contact with the surface of the measurement point, forming a complete coverage of the measurement point, avoiding the heat generated by the human body and/or the temperature-controlled heating device The heat generated is dissipated from the voids in the human skin, which completely blocks the heat loss from the measuring point to the outside.

In this embodiment, the flexible thermal insulation body 12 is preferably a filling material with elasticity, air permeability and thermal insulation properties such as sponge and cotton, and the packaging material 11 is also made of fabrics such as cloth with good air permeability. Since the zero-heat fluid thermometer measures body temperature continuously for a long time in most cases, the temperature sensing probe 3 needs to be pressed and covered on the body surface. Therefore, the flexible heating body 1 with good air permeability can greatly reduce the irritation to the skin and improve the user experience.

Further, the flexible heating body 1 protrudes outwardly on one side of the heating element 13 , and the temperature sensor 2 is disposed on the outwardly protruding area of the flexible heating body 1 .

In this embodiment, the flexible heating body 1 protrudes outwardly on the side where the heating element 13 is arranged, and the temperature sensor 2 is disposed on the outwardly convex region of the flexible heating body 1 . The convex flexible heating body 1 can better press the surface of the measurement point and completely cover the uneven skin on the surface of the measurement point. However, the temperature sensor 2 is arranged on the convex area of the flexible heating body 1, so that the temperature sensor 2 can be better in close contact with the surface of the measuring point. Preferably, the convex area is located in the center of the flexible heating body 1 . After the temperature sensor 2 is deployed on the surface of the measurement point, the volume of the body of the temperature sensor 2 will support the surface of the flexible heating body 1 for a certain space, and the convex area is located in the center of the flexible heating body 1, which can make the flexible heating body 1 and the surface of the measurement point. The contact area is evenly distributed (with the temperature sensor 2 as the center), the flexible heating body 1 can better ensure the complete coverage of the measurement point area, effectively improve the accuracy of the zero-heat fluid temperature measurement, and also facilitate the user to deploy the temperature probe 3 .

Further, the flexible heating body 1 further includes a plurality of medium sensors 14 , each of the medium sensors 14 is arranged inside the flexible heating body 1 and is on the same layer as the heating element 13 , and each of the medium sensors 14 is disposed inside the flexible heating body 1 . There is no contact with the heating element 13 .

Preferably, referring to FIG. 3 , the number of the medium sensors 14 is not less than four, and each of the medium sensors 14 is deployed around the temperature sensor 2 .

In this embodiment, the flexible heating body 1 further includes a plurality of medium sensors 14 , and each medium sensor 14 is disposed inside the flexible heating body 1 and is located in the same layer in the flexible heating body 1 as the heating element 13 . The medium sensor 14 and the heating element 13 are not in contact with each other, so as to avoid damage to the medium sensor 14 due to the heating of the heating element 13 . The medium sensor 14 is used to detect whether the flexible heating body 1 is in complete contact with the surface of the measuring point (ie, human skin) during the process of measuring the body temperature by the temperature sensing probe 3 . Specifically, the medium sensor 14 is preferably a capacitive sensor, and the capacitive sensor will output different capacitance values according to different distances from the human skin. Since the capacitance sensor and the heating file are on the same layer, the designer can set a corresponding capacitance value interval according to the model of the capacitance sensor, etc., and the capacitance value interval essentially represents the difference between the layer where the heating element 13 is located and the surface of the measurement point. distance interval. The capacitance value interval set by the designer is the distance interval corresponding to the complete contact between the flexible heating body 1 and the surface of the measurement point. When the capacitance values output by each capacitance sensor are in the capacitance value range, it means that the flexible heating body 1 is in complete contact with the measurement point, or the fit between the flexible heating body 1 and the measurement point reaches the preset standard, and the flexible heating body 1 can To achieve complete coverage of the measurement points, the current measured temperature value has a high degree of confidence, effectively ensuring the accuracy of the measurement. When the capacitance value output by one or more capacitive sensors is not in the capacitance value range, the area of the flexible heating body 1 corresponding to the deployment position of the capacitive sensor is separated from the surface of the measurement point, and the flexible heating body 1 is attached to the measurement point. The degree of conformity does not meet the preset standard, that is, the flexible heating body 1 does not achieve complete coverage of the measurement point. Therefore, the confidence of the temperature value measured this time is low, and it is necessary to perform thermal compensation on the detection result.

Preferably, the number of medium sensors 14 is not less than 4, and each medium sensor 14 is arranged around the temperature sensor 2 with the temperature sensor 2 as the center. Wherein, the distances between the media sensors 14 are equal, so that the distribution of the media sensors 14 is uniform. When the temperature sensor 3 is in use, the temperature sensor 2 needs to be in close contact with the measurement point, so the number of medium sensors 14 is selected to be no less than 4, and each medium sensor 14 is deployed around the temperature sensor 2, which can ensure the maximum temperature sensor. 2. The surrounding flexible heating body 1 is in complete contact with the surface of the measurement point, which improves the monitoring efficiency of the medium sensor 14.

Further, the heating element 13 is a conductive cloth, conductive sponge or conductive silica gel, and is integrally laid in the flexible heating body 1;

A split hole is formed on the conductive cloth, the conductive sponge or the conductive silica gel, and the medium sensor 14 is arranged at the split hole.

In this embodiment, the heating element 13 is preferably a conductive cloth, conductive sponge or conductive silica gel, which is a large-area block as a whole, has the ability to deform, and can be laid in the flexible heating body 1 as a whole, forming a different division from the flexible thermal insulation body 12 . Floor. The conductive cloth, conductive sponge or conductive silicone is provided with a split hole, wherein, there are some defects on the whole heating cloth (ie conductive cloth, conductive sponge or conductive silicone), and these defects can deploy those elements that cannot touch the heating element 13. , This kind of intentional defect in craftsmanship is called splitting. Each medium sensor 14 is respectively deployed in the split space on the conductive cloth, conductive sponge or conductive silica gel to avoid direct contact with heating.

Further, the temperature sensing probe 3 further includes a heat insulating layer, and the heat insulating layer is arranged between the temperature sensor 2 and the flexible heating body 1 .

In this embodiment, the temperature sensing probe 3 further includes a heat insulating layer, and the heat insulating layer is made of conventional heat insulating materials. The heat insulating layer is preferably a heat insulating film, which has a certain deformability and a small thickness. The heat insulation layer is arranged between the temperature sensor 2 and the flexible heating body 1 to prevent the flexible heating body 1 from being heated up from causing damage to the temperature sensor 2 .

The zero-heat-flux temperature probe 3 provided in this embodiment includes a flexible heating body 1 and a temperature sensor 2 , and the flexible heating body 1 includes a packaging material 11 , a flexible thermal insulation body 12 and a temperature-controlled heating device. The temperature-controlled heating device includes a heating element 13, the heating element 13 and the flexible thermal insulation body 12 are stacked and deployed, and the wrapping material 11 completely wraps the flexible thermal insulation body 12 and the heating element 13, thereby forming a flexible heating body 1 with elastic deformation as a whole. The temperature sensor 2 is deployed on the outer surface of the flexible heating body 1 on the same side as the heating element 13 . During use, the temperature sensor 2 is deployed at the measurement point of the human body (for example, the temperature sensor 3 is clamped under the armpit). After the entire flexible heating body 1 is compressed, due to its ductility, the flexible heating body 1 is deployed with a temperature One side of the sensor 2 can be in complete contact with the surface of the measurement point, filling the gap between the human skin, so as to form a complete coverage of the measurement point and completely block the measurement point from dissipating heat outward. The temperature-controlled heating device is connected to the temperature sensor 2, and can perform the corresponding heating action according to the detected temperature of the temperature sensor 2, forcing the temperature of the measurement point to be close to the core temperature deep under the skin, and effectively improving the temperature measurement accuracy.

Referring to FIG. 4 , this embodiment also provides a zero-heat fluid temperature detection device, including a processor and the above-mentioned temperature sensing probe 3;

The processor is connected to the temperature sensor 2 and the flexible heating body 1 respectively;

The processor is used for processing the detection signal of the temperature sensor 2 and the feedback information of the flexible heating body 1 .

In this embodiment, the zero-heat fluid temperature detection device includes a processor and the above-mentioned zero-heat-flux temperature probe 3 (hereinafter referred to as the temperature probe 3 ), and the processor is connected to the temperature sensor 2 and the flexible heating body 1 respectively. Specifically, the processor is connected to the temperature control heating device in the flexible heating body 1 , and the processor is used for processing the detection signal of the temperature sensor 2 and the feedback information of the flexible heating body 1 . The temperature sensing probe 3 includes a flexible heating body 1 and a temperature sensor 2, wherein the flexible heating body 1 includes a packaging material 11, a flexible thermal insulation body 12 and a temperature-controlled heating device. The temperature-controlled heating device includes a heating element 13 , a temperature switch, a temperature relay and a power supply, and is connected to the temperature sensor 2 , and can perform a corresponding heating action according to the detection signal of the temperature sensor 2 , that is, the detected temperature measured by the temperature sensor 2 . Specifically, the temperature-controlled heating device is used to heat the flexible heating body 1 , and the temperature-controlled heating device needs to ensure that the object to be heated, that is, the first temperature of the flexible heating body 1 is kept consistent with the detection temperature measured by the temperature sensor 2 . When the temperature-controlled heating device detects that the first temperature of the object to be heated is lower than the detected temperature of the temperature sensor 2, the relay in the temperature-controlled heating device closes the circuit, and the heating element 13 starts to work and start heating. When the first temperature of the heated object rises to be consistent with the detected temperature, the temperature relay controls the temperature switch to turn off, thereby cutting off the connection between the heating element 13 and the power supply, and the temperature-controlled heating device stops heating. Since the temperature control heating device generates a temperature consistent with the measurement point in the direction of heat loss, it can block the heat loss of the measurement point, and at the same time, it will not actively generate heat to affect the temperature rise of the measurement point, which greatly increases the temperature so that the measurement point reaches External thermal impedance. After a certain period of time, the temperature of the flexible heating body 1 is consistent with the temperature detected by the temperature sensor 2, that is, the temperature of the measurement point. At this time, the temperature of the measurement point will be equivalent to the core body temperature deep under the human body, effectively increasing the body temperature. detection accuracy. Preferably, the heating element 13 and the flexible thermal insulation body 12 are arranged inside the flexible heating body 1, and the two are stacked and deployed therebetween. The packaging material 11 completely wraps the flexible thermal insulation body 12 and the heating element 13 to form the flexible heating body 1 with elasticity and ductility as a whole. Other components of the temperature-controlled heating device, such as temperature relays, temperature switches, etc., can be deployed inside the flexible heating body 1, or can be arranged outside the flexible heating body 1 (for example, arranged on the outer surface of the packaging material 11). Those skilled in the art Corresponding location deployment can be performed as required, which is not limited here. The temperature sensor 2 is disposed on the outer surface of the flexible heating body 1 , that is, mounted on the packaging material 11 , and the temperature sensor 2 and the heating element 13 are located on the same side of the flexible heating body 1 . When the temperature probe 3 is in use, the temperature sensor 2 is arranged at the human body measurement point, and the side of the flexible heating body 1 where the temperature sensor 2 is arranged is attached to the surface of the measurement point (ie, human skin). The flexible heating body 1 itself has good elasticity and ductility. After the whole is compressed (for example, the temperature sensing probe 3 is clamped under the armpit), a certain deformation will occur, and the flexible heating body 1 will fill the gap between the human skin. . Even after the temperature sensing probe 3 is deployed, the user's limb movements cause the human tissues to pull and disturb each other, and the flatness of the surface of the measurement point changes. The deformation corresponding to the surface of the measurement point, so that the side of the flexible heating body 1 on which the temperature sensor 2 is deployed can be in complete contact with the surface of the measurement point, forming a complete coverage of the measurement point, avoiding the heat generated by the human body and/or the temperature-controlled heating device The heat generated is dissipated from the voids in the human skin, which completely blocks the heat loss from the measuring point to the outside.

During use of the body temperature detection device, the processor monitors in real time whether the detected temperature of the temperature sensor 2 is the same as the first temperature of the heated object (ie, the flexible heating body 1 ) of the temperature-controlled heating device. If the detected temperature is different from the first temperature, the temperature control heating device is controlled to generate heat, and the first temperature of the entire flexible heating body 1 is adjusted to be the same as the detected temperature measured by the temperature sensor 2 . After the first temperature is adjusted to be the same as the detected temperature, the processor monitors whether the detected temperature remains unchanged within a preset time period. If the detected temperature remains unchanged within the preset time period, it means that the detected temperature measured by the temperature sensor 2 on the surface of the human skin is equivalent to the core temperature under the human skin. At this time, the processor takes the detected temperature as the first detection result, and passes The display device 4 of the body temperature detection device outputs.

Preferably, several medium sensors 14 are also deployed in the flexible heating body 1, and the working principles and deployment positions thereof are as described above. The processor is respectively connected to each medium sensor 14, and receives the capacitance value output by each medium sensor 14, so that whether the whole flexible heating body 1 is in complete contact with the surface of the measurement point can be judged by the capacitance value output by each medium sensor 14. Specifically, the medium sensor 14 is preferably a capacitive sensor, and the capacitive sensor will output different capacitance values according to different distances from the human skin. Since the capacitance sensor and the heating file are on the same layer, the designer can set a corresponding capacitance value interval according to the model of the capacitance sensor, etc., and the capacitance value interval essentially represents the difference between the layer where the heating element 13 is located and the surface of the measurement point. distance interval. The capacitance value interval set by the designer is the distance interval corresponding to the complete contact between the flexible heating body 1 and the surface of the measurement point. When the capacitance values output by each capacitance sensor are in the capacitance value range, it means that the flexible heating body 1 is in complete contact with the measurement point, or the fit between the flexible heating body 1 and the measurement point reaches a preset standard. When the processor finds that the capacitance value output by one or more capacitance sensors is not within the capacitance value range, it means that the flexible heating body 1 area corresponding to the deployment position of the capacitance sensor whose capacitance value is not within the capacitance value range is separated from the surface of the measurement point. , the flexible heating body 1 does not achieve complete coverage of the measurement point. At this time, the processor will trigger an alarm mechanism to notify the user that the confidence of the current measurement result is low, and the temperature sensing probe 3 does not completely cover the measurement point. Furthermore, the processor needs to perform thermal compensation on the measurement result measured by the temperature sensing probe 3 . Specifically, the processor adds a compensation value to the first detection result (that is, the current measurement result measured by the temperature sensing probe 3) to obtain a second detection result, and then uses the second detection result as the final output result, and outputs to display device 4. For example, if the first detection result measured by the temperature sensing probe 3 for the current time is 37.1°C, the processor will add a compensation value on the basis of the first detection to obtain the second detection result of 37.3°C. The setting of the compensation value is preset by the designer and stored in the processor, and the designer can obtain the compensation value through multiple experiments, which will not be described in detail here.

The zero-heat fluid temperature detection device provided in this embodiment includes a processor and a temperature sensing probe 3. The temperature sensing probe 3 includes a flexible heating body 1 and a temperature sensor 2. The flexible heating body 1 includes a packaging material 11, a flexible thermal insulation body 12 and a temperature control heating equipment. The temperature-controlled heating device includes a heating element 13, the heating element 13 and the flexible thermal insulation body 12 are stacked and deployed, and the wrapping material 11 completely wraps the flexible thermal insulation body 12 and the heating element 13, thereby forming a flexible heating body 1 with elastic deformation as a whole. The temperature sensor 2 is deployed on the outer surface of the flexible heating body 1 on the same side as the heating element 13 . During use, the temperature sensor 2 is deployed at the measurement point of the human body (for example, the temperature sensor 3 is clamped under the armpit). After the entire flexible heating body 1 is compressed, due to its ductility, the flexible heating body 1 is deployed with a temperature One side of the sensor 2 can be in complete contact with the surface of the measurement point, filling the gap between the human skin, so as to form a complete coverage of the measurement point and completely block the measurement point from dissipating heat outward. The temperature-controlled heating device is connected to the temperature sensor 2, and can perform the corresponding heating action according to the detected temperature of the temperature sensor 2, forcing the temperature of the measurement point to be close to the core temperature deep under the skin, and effectively improving the temperature measurement accuracy.

Referring to FIG. 5 , the present embodiment also provides a method for using a zero-thermal fluid temperature detection device, wherein the zero-thermal fluid temperature detection device is the above-mentioned zero-thermal fluid temperature detection device, and the using method includes:

S1: monitor in real time whether the detected temperature of the temperature sensor 2 is the same as the first temperature of the flexible heating body 1;

S2: if the detected temperature is different from the first temperature, then control the flexible heating body 1 to adjust the first temperature to be the same as the detected temperature;

S3: after the first temperature is adjusted to be the same as the detected temperature, monitor whether the detected temperature remains unchanged within a preset time period;

S4: If the detected temperature remains unchanged within a preset time period, the detected temperature is used as the first detection result.

In this embodiment, the body temperature detection device obtains the detected temperature of the measurement point through the temperature sensor 2 of the temperature sensing probe 3; at the same time, it can obtain the temperature-controlled temperature through the temperature-sensitive unit (the temperature-sensitive unit can be a temperature sensor) of the temperature-controlled heating device itself. The entire flexible heating body 1 heated by the heating element 13 of the heating device is the first temperature of the heated object. The working principle of the temperature sensing probe 3 has been explained above, the temperature control heating device will perform corresponding heating actions according to the detected temperature of the temperature sensor 2, and the temperature control heating device will ensure that the first temperature of the heated object is maintained at the same temperature as the temperature sensor 2. The measured detection temperature is kept consistent, so as to block the heat loss from the measurement point to the surroundings, and finally force the temperature measured by the temperature sensor 2 at the measurement point (human skin surface) to be close to or even consistent with the core body temperature of the human body subcutaneous depth. The body temperature detection device will monitor in real time whether the detected temperature of the temperature sensor 2 is the same as the first temperature of the heated object of the temperature-controlled heating device. If the detected temperature is different from the first temperature, the body temperature detection device will control the temperature control heating device to work, and the first temperature of the heated object is adjusted to be the same as the detected temperature measured by the temperature sensor 2 through the heating element 13 . Moreover, after the body temperature detection device monitors that the first temperature of the heated object has been adjusted to the same detection temperature, it is necessary to monitor whether the detection temperature measured by the temperature sensor 2 at the measurement point remains unchanged within a preset time period. If the detected temperature changes within a preset time period, such as an increase in temperature, it means that the detected temperature currently measured by the temperature sensor 2 is inconsistent with the core body temperature deep under the human body, and the temperature detection device needs to pass the temperature control heating device. Adjust the first temperature of the flexible heating body 1 again. If the detected temperature remains unchanged within the preset time period, it means that the detected temperature currently measured by the temperature sensor 2 is close to or even consistent with the core body temperature deep under the human body, and its measurement accuracy is high, and the body temperature detection device will detect the temperature as the first detection result of the current temperature detection. The subsequent body temperature detection device may output the first detection result to the display interface, so that the user can know the body temperature measurement result.

Further, the using method also includes:

S5: monitor in real time whether the degree of fit of the measurement surface of the flexible heating body 1 and the temperature measurement point reaches a preset standard, wherein the measurement surface is the side where the flexible heating body 1 is arranged with the temperature sensor 2;

S6: If the fit between the measurement surface of the flexible heating body 1 and the temperature measurement point does not reach the preset standard, trigger an alarm and thermal compensation.

In this embodiment, several medium sensors 14 are deployed in the flexible heating body 1 of the body temperature detection device. Therefore, the body temperature detection device can monitor the flexibility in real time through the capacitance values output by each medium sensor 14 during the whole process of body temperature detection. Whether the fit between the measuring surface of the heating body 1 and the temperature measuring point reaches the preset standard. Among them, the measurement surface refers to the side of the flexible heating body 1 where the temperature sensor 2 is arranged. When the temperature sensor 3 is used for body temperature detection, the measurement surface needs to be in complete contact with the surface of the measurement point, or the fit between the two must reach Preset criteria to block heat loss from the measurement point to the surroundings. The value of the preset standard has different settings according to different shapes and sizes of the flexible heating body 1 , and is specifically set by the designer according to the experimental results, which will not be described in detail here. Specifically, the medium sensor 14 is preferably a capacitive sensor, and the capacitive sensor will output different capacitance values according to different distances from the human skin. Since the capacitance sensor and the heating file are on the same layer, the designer can set a corresponding capacitance value interval according to the model of the capacitance sensor, etc., and the capacitance value interval essentially represents the difference between the layer where the heating element 13 is located and the surface of the measurement point. distance interval. The capacitance value interval set by the designer is the distance interval corresponding to the complete contact between the flexible heating body 1 and the surface of the measurement point. When the capacitance values output by each capacitance sensor are in the capacitance value range, it means that the fit between the flexible heating body 1 and the temperature measurement point reaches the preset standard. When the processor finds that the capacitance value output by one or more capacitance sensors is not within the capacitance value range, it means that the flexible heating body 1 area corresponding to the deployment position of the capacitance sensor whose capacitance value is not within the capacitance value range is separated from the surface of the measurement point. , the fit between the flexible heating body 1 and the temperature measurement point does not reach the preset standard, and the flexible heating body 1 does not achieve complete coverage of the measurement point. If the body temperature detection device detects that the fit between the measurement surface of the flexible heating body 1 and the temperature measurement point does not reach the preset standard, it will trigger an alarm and thermal compensation. Specifically, after the body temperature detection device triggers the alarm mechanism, it notifies the user that the confidence of the current measurement result is low, and the temperature sensing probe 3 does not completely cover the measurement point. In addition, the body temperature detection device needs to perform thermal compensation on the measurement result measured by the temperature sensing probe 3, and add a compensation value to the first detection result to obtain the second detection result. Finally, the body temperature detection device uses the second detection result and the label information as the output result, wherein the label information is the remark information after the alarm mechanism is triggered, which is used to explain that the second detection result outputted this time is obtained through the compensation mechanism, and the confidence level is lower.

Further, after the step of triggering thermal compensation, it includes:

S7: adding a compensation value to the first detection result to obtain the second detection result;

S8: Use the second detection result and the labeling information as an output result.

In this embodiment, the body temperature detection device adds a compensation value to the first detection result to obtain the second detection result, and then uses the second detection result as the final output result to output to the display device 4 . For example, if the first detection result measured by the temperature sensing probe 3 for the current time is 37.1°C, the processor will add a compensation value on the basis of the first detection to obtain the second detection result of 37.3°C. The setting of the compensation value is preset by the designer and stored in the processor, and the designer can obtain the compensation value through multiple experiments, which will not be described in detail here.

In the method of using the zero-heat fluid temperature detection device provided in this embodiment, the body temperature detection device uses the temperature control heating device to generate a temperature consistent with the measurement point in the direction of heat loss at the measurement point, preventing the measurement point from losing heat to the surroundings. In addition, the temperature-controlled heating device will not actively generate heat to affect the temperature rise of the measurement point, which greatly improves the thermal impedance between the temperature measurement point and the body, and finally forces the temperature of the measurement point to be close to or even equal to the core body temperature deep under the skin. The measurement accuracy of the body temperature detection device is effectively improved.
