Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
Referring to fig. 1 and 2, in an embodiment of the present application, a zero heat flow temperature sensing probe 3 is provided, which includes 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 for measuring temperature;
the flexible heating body 1 is used for blocking heat loss of the temperature measuring point corresponding to the temperature sensor 2.
Preferably, the flexible heating body 1 comprises a packing material 11, a flexible heat insulator 12 and a temperature control heating device;
the temperature control heating device is connected with the temperature sensor 2 and is used for executing corresponding heating action according to a detection signal of the temperature sensor 2;
the temperature controlled heating device comprises a heating element 13, and the heating element 13 and the flexible thermal insulator 12 are arranged in a stacked manner;
the packing 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 positioned on the same side as the heating element 13.
In this embodiment, the temperature sensing probe 3 includes a flexible heating member 1 and a temperature sensor 2, and the temperature sensor 2 is disposed on the flexible heating member 1. The temperature sensor 2 is used for measuring temperature, and when the temperature sensor 2 is used for measuring a temperature measuring point (such as the surface of human skin), the flexible heating body 1 is pressed to be tightly attached to the temperature measuring point. When the surface of the temperature measuring point has a gap due to the traction disturbance of the movement of the user, the gap can be automatically filled because the whole flexible heating body 1 has the ductility and the elasticity, so that the heat loss of the temperature measuring point is blocked.
Preferably, the flexible heating body 1 comprises a packing material 11, a flexible heat insulator 12 and a temperature-controlled heating device. The temperature-controlled heating device comprises a heating element 13, a temperature switch, a temperature relay and a power supply, is connected with the temperature sensor 2, and can execute corresponding heating action according to a detection signal of the temperature sensor 2, namely, the detection temperature measured by the temperature sensor 2. Specifically, the temperature-controlled heating device is used for heating 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 detection temperature measured by the temperature sensor 2. When the temperature-controlled heating device detects that the first temperature of the heated object is lower than the detection temperature of the temperature sensor 2, a relay in the temperature-controlled heating device closes a circuit, and the heating element 13 starts to operate to start heating. When the first temperature of the heated object rises to coincide with the detected temperature, the temperature relay controls the temperature switch to be turned off, thereby disconnecting the heating element 13 from the power supply and the temperature controlled heating device stops heating. Because the temperature control heating device generates the temperature consistent with the measuring point in the heat loss direction, the heat loss of the measuring point is blocked, and meanwhile, heat can not be generated actively to influence the temperature rise of the measuring point, so that the temperature is greatly improved, and the thermal impedance from the measuring point to the outside of the body is greatly improved. 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, namely the temperature of the measuring point is kept, the temperature of the measuring point is equal to the core body temperature of the subcutaneous deep part of the human body, and the accuracy of body temperature detection is effectively improved. Preferably, the heating element 13 and the flexible thermal insulator 12 are disposed inside the flexible heating body 1, and are disposed in a stacked manner therebetween. The packing material 11 completely wraps the flexible heat insulation body 12 and the heating element 13 to form the flexible heating body 1 with elastic deformation capability as a whole. Other components of the temperature control heating device, such as a temperature relay, a temperature switch, etc., can be disposed inside the flexible heating body 1, and also can be disposed outside the flexible heating body 1 (for example, disposed on the outer surface of the packing material 11), and those skilled in the art can perform corresponding position disposition as required, and are not limited herein. The temperature sensor 2 is arranged on the outer surface of the flexible heating body 1, i.e. 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 sensing probe 3 is used, the temperature sensor 2 is aligned with a human body measuring point to be arranged, and the surface of the flexible heating body 1, on which the temperature sensor 2 is arranged, is attached to the surface of the measuring point (namely, the skin of the human body). The flexible heating body 1 has good elasticity and ductility, and can deform to a certain extent after being pressed integrally (for example, the temperature sensing probe 3 is clamped under an armpit), and the flexible heating body 1 can be filled in a gap between skins of a human body. Even if the temperature sensing probe 3 is deployed, the user generates limb actions to cause mutual traction disturbance between human tissues, the flatness of the surface of a measuring point changes, the flexible heating body 1 with elasticity and ductility can also generate deformation corresponding to the surface of the measuring point under the action of pressure, so that one surface of the flexible heating body 1, on which the temperature sensor 2 is deployed, can be in complete contact with the surface of the measuring point, complete coverage of the measuring point is formed, heat generated by a human body and/or heat generated by a temperature control heating device is prevented from flowing away from the gap of the skin of the human body, and heat loss of the measuring point outwards is completely prevented.
In this embodiment, the flexible thermal insulation body 12 is preferably a filling material such as sponge or cotton having elasticity, air permeability and thermal insulation performance, and the packing material 11 is also a fabric such as cloth having good air permeability. Since the zero heat flow thermometer is used for continuously measuring the body temperature for a long time in most cases, the temperature sensing probe 3 needs to be pressed to cover the body surface. Therefore, the flexible heating body 1 with good air permeability can greatly reduce the stimulation to the skin and improve the use experience of the user.
Further, the flexible heating body 1 protrudes outward from one side of the heating element 13, and the temperature sensor 2 is disposed in the protruding region of the flexible heating body 1.
In this embodiment, the flexible heating body 1 protrudes outward from the side where the heating element 13 is disposed, and the temperature sensor 2 is disposed in the protruding region of the flexible heating body 1. The convex flexible heating body 1 can better press the surface of the measuring point and completely cover the uneven skin on the surface of the measuring point. And the temperature sensor 2 is arranged at the convex region 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 outer convex region is located in the center of the flexible heating body 1. Temperature sensor 2 deploys behind the measuring point surface, the volume of temperature sensor 2 body can prop up certain space with the surface of flexible heating body 1, and the evagination region is located flexible heating body 1 center, can make the contact area on flexible heating body 1 and measuring point surface distribute evenly (use temperature sensor 2 to distribute as the center), the assurance that flexible heating body 1 can be better covers the regional complete of measuring point, effectively improve zero hot-fluid temperature measuring's precision, also convenience of customers deploys temperature sensing probe 3.
Further, the flexible heating body 1 further includes a plurality of media sensors 14, each of the media sensors 14 is disposed inside the flexible heating body 1, and is in the same layer as the heating element 13, and each of the media sensors 14 is not in contact with the heating element 13.
Preferably, referring to fig. 3, the number of the media sensors 14 is not less than 4, and each of the media sensors 14 is disposed around the temperature sensor 2.
In this embodiment, flexible heating body 1 further includes a plurality of medium sensors 14, and each medium sensor 14 is disposed inside flexible heating body 1 and is located on the same layer in flexible heating body 1 as heating element 13. The medium sensor 14 and the heating element 13 are not in contact with each other, so that the medium sensor 14 is prevented from being damaged due to heat generated by the heating element 13. The medium sensor 14 is used for detecting whether the flexible heating body 1 is completely contacted with the surface of a measuring point (namely human skin) or not in the process of measuring the body temperature by the temperature sensing probe 3. In particular, the dielectric sensor 14 is preferably a capacitive sensor that outputs different capacitance values depending on the distance from the skin of the human body. Since the capacitive sensor and the heating file are on the same layer, a designer can set a corresponding capacitance value interval according to the type of the capacitive sensor, and the capacitance value interval substantially represents a distance interval between the layer where the heating element 13 is located and the surface of the measurement point. The capacitance value interval set by the designer is a distance interval corresponding to the complete contact between the flexible heating body 1 and the surface of the measuring point. When the capacitance values output by the capacitance sensors are all in the capacitance value interval, it is indicated that the flexible heating body 1 is in complete contact with the measuring point, or the fitting degree of the flexible heating body 1 and the measuring point reaches the preset standard, the flexible heating body 1 can completely cover the measuring point, the temperature value measured at the current time has high confidence level, and the measuring accuracy is effectively guaranteed. And when the capacitance value that appears one or more capacitive sensor output is not in the capacitance value interval, then this capacitive sensor disposes the flexible heating body 1 region that the position corresponds, breaks away from with the measuring point surface, and the laminating degree of flexible heating body 1 and measuring point does not reach the preset standard, and flexible heating body 1 does not realize the complete cover to the measuring point promptly. Therefore, the confidence of the temperature value measured at the current time is low, and the detection result needs to be thermally compensated.
Preferably, the number of the media sensors 14 is not less than 4, and each of the media sensors 14 is disposed around the temperature sensor 2 centering on the temperature sensor 2. Wherein the media sensors 14 are equally spaced apart, thereby providing a uniform distribution of the media sensors 14. When the temperature sensing probe 3 is used, the temperature sensors 2 need to be in close contact with a measuring point, so that the number of the medium sensors 14 is not less than 4, and each medium sensor 14 is arranged around the temperature sensor 2, so that the flexible heating body 1 around the temperature sensor 2 can be ensured to be in complete contact with the surface of the measuring point to the maximum extent, and the monitoring efficiency of the medium sensors 14 is improved.
Further, the heating element 13 is conductive cloth, conductive sponge or conductive silica gel, and is integrally laid in the flexible heating body 1;
the conductive cloth, the conductive sponge or the conductive silica gel are provided with gaps, and the medium sensor 14 is arranged at the gaps.
In this embodiment, the heating element 13 is preferably a conductive cloth, a conductive sponge or a conductive silica gel, and is a block with a large area as a whole, has a deformation capability, and can be integrally laid in the flexible heating body 1 to form different layers with the flexible thermal insulator 12. The conductive cloth, the conductive sponge or the conductive silica gel is provided with a split, wherein the whole piece of heating cloth (i.e. the conductive cloth, the conductive sponge or the conductive silica gel) has defects, the defects can be used for deploying elements which can not contact the heating element 13, and the intentional defect is called the split in the process. Each dielectric sensor 14 is disposed at a split on a conductive cloth, a conductive sponge or a conductive silica gel, respectively, to avoid direct contact with the heating.
Further, the temperature sensing probe 3 further comprises a heat insulation layer, and the heat insulation 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 made of a conventional heat insulating material. The heat insulating layer is preferably a heat insulating film, has certain deformation capacity and is small in thickness. The heat insulating layer is arranged between the temperature sensor 2 and the flexible heating body 1, and damage to the temperature sensor 2 caused by the heated flexible heating body 1 is avoided.
The zero heat flow temperature sensing probe 3 provided by the embodiment comprises a flexible heating body 1 and a temperature sensor 2, wherein the flexible heating body 1 comprises a packing material 11, a flexible heat preservation body 12 and a temperature control heating device. The temperature control heating device comprises a heating element 13, the heating element 13 and a flexible heat insulator 12 are arranged in a stacked mode, and the flexible heat insulator 12 and the heating element 13 are completely wrapped by a wrapping material 11, so that the flexible heating body 1 with elastic deformation is formed integrally. The temperature sensor 2 is disposed on the outer surface of the flexible heating body 1, on the same side as the heating element 13. In the use, temperature sensor 2 aligns the human measuring point and deploys (for example press from both sides temperature sensing probe 3 in the armpit), and flexible heating body 1 is whole to be compressed the back, because the ductility of itself, and flexible heating body 1 deploys the one side that has temperature sensor 2 and can fill the space between human skin with the complete contact in measuring point surface to form the complete cover to measuring point, realize stopping completely that measuring point outwards loses the heat. Temperature control heating device is connected with temperature sensor 2, can carry out corresponding heating action according to temperature sensor 2's detection temperature, forces the measuring point temperature to be close to the core temperature of subcutaneous depths, effectively improves the measurement accuracy of temperature.
Referring to fig. 4, the present embodiment further provides a zero heat flow body temperature detecting device, which includes a processor and the temperature sensing probe 3;
the processor is respectively connected with the temperature sensor 2 and the flexible heating body 1;
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 flow body temperature detecting device includes a processor and the zero heat flow temperature sensing probe 3 (hereinafter referred to as the temperature sensing probe 3), and the processor is connected to the temperature sensor 2 and the flexible heating body 1, respectively. Specifically, the processor is connected with 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 comprises a flexible heating body 1 and a temperature sensor 2, wherein the flexible heating body 1 comprises a packing material 11, a flexible heat insulator 12 and a temperature control heating device. The temperature-controlled heating device comprises a heating element 13, a temperature switch, a temperature relay and a power supply, is connected with the temperature sensor 2, and can execute corresponding heating action according to a detection signal of the temperature sensor 2, namely, the detection temperature measured by the temperature sensor 2. Specifically, a temperature-controlled heating device is used for heating the flexible heating body 1, and the temperature-controlled heating device needs to ensure that the first temperature of the heated object, i.e., 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 heated object is lower than the detection temperature of the temperature sensor 2, a relay in the temperature-controlled heating device closes a circuit, and the heating element 13 starts to operate to start heating. When the first temperature of the heated object rises to coincide with the detected temperature, the temperature relay controls the temperature switch to be turned off, thereby disconnecting the heating element 13 from the power supply and the temperature controlled heating device stops heating. Because the temperature control heating device generates the temperature consistent with the measuring point in the heat loss direction, the heat loss of the measuring point is blocked, and meanwhile, heat can not be generated actively to influence the temperature rise of the measuring point, so that the temperature is greatly improved, and the thermal impedance from the measuring point to the outside of the body is greatly improved. 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, namely the temperature of the measuring point is kept, the temperature of the measuring point is equal to the core body temperature of the subcutaneous deep part of the human body, and the accuracy of body temperature detection is effectively improved. Preferably, the heating element 13 and the flexible thermal insulator 12 are disposed inside the flexible heating body 1, and are disposed in a stacked manner therebetween. The packing material 11 completely wraps the flexible heat 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 control heating device, such as a temperature relay, a temperature switch, etc., can be disposed inside the flexible heating body 1, and also can be disposed outside the flexible heating body 1 (for example, disposed on the outer surface of the packing material 11), and those skilled in the art can perform corresponding position disposition as required, and are not limited herein. The temperature sensor 2 is arranged on the outer surface of the flexible heating body 1, i.e. 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 sensing probe 3 is used, the temperature sensor 2 is aligned with a human body measuring point to be arranged, and the surface of the flexible heating body 1, on which the temperature sensor 2 is arranged, is attached to the surface of the measuring point (namely, the skin of the human body). The flexible heating body 1 has good elasticity and ductility, and can deform to a certain extent after being pressed integrally (for example, the temperature sensing probe 3 is clamped under an armpit), and the flexible heating body 1 can be filled in a gap between skins of a human body. Even if the temperature sensing probe 3 is deployed, the user generates limb actions to cause mutual traction disturbance between human tissues, the flatness of the surface of a measuring point changes, the flexible heating body 1 with elasticity and ductility can also generate deformation corresponding to the surface of the measuring point under the action of pressure, so that one surface of the flexible heating body 1, on which the temperature sensor 2 is deployed, can be in complete contact with the surface of the measuring point, complete coverage of the measuring point is formed, heat generated by a human body and/or heat generated by a temperature control heating device is prevented from flowing away from the gap of the skin of the human body, and heat loss of the measuring point outwards is completely prevented.

If the detection temperature is different from the first temperature, the temperature control heating device is controlled to emit heat, and the first temperature of the whole flexible heating body 1 is adjusted to be the same as the detection 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 is kept constant within a preset time period. If the detected temperature is kept unchanged within the preset time period, it indicates that the detected temperature measured by the temperature sensor 2 on the surface of the skin of the human body is equal to the core temperature under the skin of the human body, and at this time, the processor outputs the detected temperature as a first detection result through the display device 4 of the body temperature detection device.
Preferably, a plurality of medium sensors 14 are disposed in flexible heating body 1, and the operating principle and the disposition position thereof are as described above. The processor is connected to each of the dielectric sensors 14, and receives the capacitance values output by each of the dielectric sensors 14, so that whether the entire flexible heating body 1 is in complete contact with the surface of the measurement point can be determined by the capacitance values output by each of the dielectric sensors 14. In particular, the dielectric sensor 14 is preferably a capacitive sensor that outputs different capacitance values depending on the distance from the skin of the human body. Since the capacitive sensor and the heating file are on the same layer, a designer can set a corresponding capacitance value interval according to the type of the capacitive sensor, and the capacitance value interval substantially represents a distance interval between the layer where the heating element 13 is located and the surface of the measurement point. The capacitance value interval set by the designer is a distance interval corresponding to the complete contact between the flexible heating body 1 and the surface of the measuring point. When the capacitance values output by the capacitance sensors are all in the capacitance value interval, it indicates that the flexible heating body 1 is completely contacted with the measurement point, or the adhesion degree of the flexible heating body 1 and the measurement point reaches the preset standard. When the processor finds that the capacitance value output by one or more capacitance sensors is not in the capacitance value interval, the processor indicates that the capacitance value is not in the flexible heating body 1 area corresponding to the capacitance sensor deployment position in the capacitance value interval, and the flexible heating body 1 is separated from the surface of the measurement point, and the flexible heating body 1 does not completely cover the measurement point. At this time, the processor triggers 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. Also, the processor needs to thermally compensate the measurement result measured by the temperature sensitive probe 3. Specifically, the processor adds a compensation value to the first detection result (i.e., the measurement result currently measured by the temperature sensing probe 3) to obtain a second detection result, and then outputs the second detection result to the display device 4 as a final output result. For example, when the first detection result measured by the temperature sensing probe 3 at the current time is 37.1 ℃, the processor adds a compensation value on the basis of the first detection, and obtains a second detection result of 37.3 ℃. The compensation value is preset by a designer and then stored in the processor, and the designer can obtain the compensation value through multiple experiments, which is not described in detail herein.
The zero heat flow body temperature detection device that this embodiment provided, including treater and temperature sensing probe 3, temperature sensing probe 3 includes flexible heating body 1 and temperature sensor 2, and flexible heating body 1 includes package material 11, flexible heat retainer 12 and control by temperature change heating device. The temperature control heating device comprises a heating element 13, the heating element 13 and a flexible heat insulator 12 are arranged in a stacked mode, and the flexible heat insulator 12 and the heating element 13 are completely wrapped by a wrapping material 11, so that the flexible heating body 1 with elastic deformation is formed integrally. The temperature sensor 2 is disposed on the outer surface of the flexible heating body 1, on the same side as the heating element 13. In the use, temperature sensor 2 aligns the human measuring point and deploys (for example press from both sides temperature sensing probe 3 in the armpit), and flexible heating body 1 is whole to be compressed the back, because the ductility of itself, and flexible heating body 1 deploys the one side that has temperature sensor 2 and can fill the space between human skin with the complete contact in measuring point surface to form the complete cover to measuring point, realize stopping completely that measuring point outwards loses the heat. Temperature control heating device is connected with temperature sensor 2, can carry out corresponding heating action according to temperature sensor 2's detection temperature, forces the measuring point temperature to be close to the core temperature of subcutaneous depths, effectively improves the measurement accuracy of temperature.
Referring to fig. 5, this embodiment further provides a method for using a zero heat flow body temperature detection device, where the zero heat flow body temperature detection device is the zero heat flow body temperature detection device described above, and the method includes:
s1, monitoring whether the detection temperature of the temperature sensor 2 is the same as the first temperature of the flexible heating body 1 in real time;
s2, if the detected temperature is different from the first temperature, controlling 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 detection temperature, monitoring whether the detection temperature is kept unchanged within a preset time period;
and S4, if the detected temperature is kept unchanged in a preset time period, taking the detected temperature as a first detection result.
In this embodiment, the body temperature detection device obtains the detection temperature of the measurement point through the temperature sensor 2 of the temperature sensing probe 3; meanwhile, the first temperature of the whole flexible heating body 1 heated by the heating element 13 of the temperature-controlled heating device, i.e. the heated object, can be obtained by the temperature-sensitive unit (the temperature-sensitive unit can be a temperature sensor) of the temperature-controlled heating device itself. It has been explained in the above-mentioned working principle of the temperature sensing probe 3 that the temperature control heating device will perform a corresponding heating action 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 kept consistent with the detected temperature measured by the temperature sensor 2, so as to prevent the heat loss from the measuring point to the surroundings, and finally force the temperature measured by the temperature sensor 2 at the measuring point (the surface of the skin of the human body) to approach or even to be consistent with the core body temperature at the subcutaneous depth of the human body. The body temperature detecting means monitors 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 apparatus. If the detected temperature is different from the first temperature, the body temperature detecting device controls the temperature controlled heating device to operate, 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. Further, after the body temperature detecting means monitors that the first temperature of the heated object is adjusted to the same detected temperature, it is necessary to monitor whether or not the detected temperature measured at the measurement point by the temperature sensor 2 is kept constant for a preset time period. If the detected temperature changes within a preset time period, for example, the temperature rises, it indicates that the detected temperature currently measured by the temperature sensor 2 is inconsistent with the core body temperature of the human body at the subcutaneous depth, and at this time, the temperature detection device needs to adjust the first temperature of the flexible heating body 1 again through the temperature control heating device. If the detected temperature is kept unchanged within the preset time period, it indicates that the detected temperature currently measured by the temperature sensor 2 is close to, even consistent with, the core body temperature deep under the skin of the human body, the measurement accuracy is high, and the body temperature detection device takes the detected temperature as the first detection result of the current temperature detection. The subsequent body temperature detection device can output the first detection result to a display interface so that a user can know the body temperature measurement result.
Further, the using method further comprises the following steps:
s5, monitoring whether the fit degree of the measuring surface of the flexible heating body 1 and the temperature measuring point reaches a preset standard or not in real time, wherein the measuring surface is the surface of the flexible heating body 1, on which the temperature sensor 2 is arranged;
and S6, if the joint degree of the measuring surface of the flexible heating body 1 and the temperature measuring point does not reach the preset standard, triggering alarm and thermal compensation.
In this embodiment, a plurality of medium sensors 14 are disposed in the flexible heating body 1 of the body temperature detection device, so that the body temperature detection device can monitor whether the attachment degree of the measurement surface of the flexible heating body 1 and the temperature measurement point reaches the preset standard in real time through the capacitance value output by each medium sensor 14 in the whole process of body temperature detection. The measuring surface is the surface of the flexible heating body 1 with the temperature sensor 2, and when the temperature sensing probe 3 is used for body temperature detection, the measuring surface needs to be in complete contact with the surface of a measuring point, or the joint degree between the measuring surface and the measuring point reaches a preset standard, so that the measuring point is prevented from heat loss towards the periphery. The value of the preset standard has different settings according to the flexible heating bodies 1 with different shapes and sizes, and specifically, the designer performs corresponding settings according to experimental results, which are not described in detail herein. In particular, the dielectric sensor 14 is preferably a capacitive sensor that outputs different capacitance values depending on the distance from the skin of the human body. Since the capacitive sensor and the heating file are on the same layer, a designer can set a corresponding capacitance value interval according to the type of the capacitive sensor, and the capacitance value interval substantially represents a distance interval between the layer where the heating element 13 is located and the surface of the measurement point. The capacitance value interval set by the designer is a distance interval corresponding to the complete contact between the flexible heating body 1 and the surface of the measuring point. When the capacitance values output by the capacitance sensors are all in the capacitance value interval, the fitting degree of the flexible heating body 1 and the temperature measuring point reaches the preset standard. And when the processor finds that the capacitance value output by one or more capacitance sensors is not in the capacitance value interval, it indicates that the capacitance value is not in the flexible heating body 1 region corresponding to the capacitance sensor deployment position in the capacitance value interval, and the capacitance value is separated from the surface of the measurement point, the fitting degree of the flexible heating body 1 and the temperature measurement point does not reach the preset standard, and the flexible heating body 1 does not realize complete coverage on the measurement point. If the body temperature detection device detects that the fitting degree of the measuring surface of the flexible heating body 1 and the temperature measuring point does not reach the preset standard, an alarm and thermal compensation can be triggered. Specifically, after the body temperature detection device triggers the alarm mechanism, the user is informed 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 detecting 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 a second detection result. And finally, the body temperature detection device takes the second detection result and the labeled information as output results, wherein the labeled information is remark information after triggering an alarm mechanism and is used for explaining that the second detection result output at the current time is obtained through a compensation mechanism, and the confidence coefficient is low.
Further, after the step of triggering thermal compensation, the method includes:
s7, adding a compensation value to the first detection result to obtain a second detection result;
and S8, taking the second detection result and the label information as output results.
In this embodiment, the body temperature detecting device adds a compensation value to the first detection result to obtain a second detection result, and then outputs the second detection result to the display device 4 as a final output result. For example, when the first detection result measured by the temperature sensing probe 3 at the current time is 37.1 ℃, the processor adds a compensation value on the basis of the first detection, and obtains a second detection result of 37.3 ℃. The compensation value is preset by a designer and then stored in the processor, and the designer can obtain the compensation value through multiple experiments, which is not described in detail herein.
In the application method of the zero heat flow body temperature detection device provided by the embodiment, the body temperature detection device utilizes the temperature control heating device to generate the temperature consistent with the measurement point in the direction of heat loss of the measurement point, so that the measurement point is prevented from heat loss towards the periphery. And, the temperature control heating device can not actively generate heat to influence the temperature rise of the measuring point, so that the thermal impedance from the temperature measuring point to the outside of the body is greatly improved, the temperature of the measuring point is finally forced to be close to or even equal to the core body temperature in the subcutaneous depth, and the measuring accuracy of the body temperature detecting device is effectively improved.
