It should be noted that in the embodiments of the present application, the term "comprising" is used to indicate the presence of the features stated hereinafter, but does not exclude the addition of further features.
The human body temperature is a barometer reflecting the health condition of a human body, and the effective monitoring of the human body temperature becomes an important topic, and the clinical body temperature refers to the average core body temperature. In daily life, the temperature of armpit, oral cavity and forehead is generally measured, and the temperature is the body surface temperature in a strict sense, and has a certain error with the core body temperature. At present, the commonly used method capable of accurately measuring the core body temperature of a human body is a zero heat flow method. The schematic diagram of the zero heat flow method for measuring the core body temperature is shown in fig. 1.
Referring to fig. 1, a temperature sensor a is used to measure the temperature of the body surface, and a thermal isolation layer is used to prevent heat from dissipating from the human body to the external environment. Under ideal conditions, the thermal isolation layer can realize complete heat insulation effect, so that heat conducted from the deep part of a human body is completely retained on the body surface, and when the heat is finally balanced, the body surface temperature under the thermal isolation layer is the same as the core body temperature, namely, the body surface temperature is called as zero heat flow.
When zero heat flow is reached, the temperature measured by temperature sensor a can be taken as the core body temperature. However, since in reality, absolutely thermally insulating materials do not exist, a comparator, a heating device and a temperature sensor b are introduced to jointly perform measurement. The comparator judges whether the heating device works or not by judging the values acquired by the two temperature sensors. The heating device is used for heating the thermal isolation layer to compensate the lost heat, so that the temperature of the thermal isolation layer measured by the temperature sensor b is consistent with the body surface temperature measured by the temperature sensor a, and a zero heat flow state is formed. After a period of feedback heating control, the establishment of the thermal balance is completed, and the temperature finally measured by the temperature sensor a is regarded as the core body temperature.
From the above processes, when the core body temperature is measured by the zero-heat flow method, an active heating device is required, so that a corresponding zero-heat flow channel is formed. However, in wearable devices powered by batteries, it is a huge energy load to use batteries to provide energy for heating devices. Therefore, in wearable devices that measure the core body temperature using the zero-heat flow method, the existing additional heating device is used to heat the thermal isolation layer, which results in a significant increase in the power consumption of the battery on these devices.
This application is based on foretell problem, provides a core body temperature measuring device, through combining together blood oxygen measuring module and core body temperature measuring module, both can measure the blood oxygen, can measure core body temperature again, moreover, owing to not only use supplementary heating element to heat the heat isolation layer, also use blood oxygen measuring module to heat the heat isolation layer simultaneously, and then reduced the required energy of supplementary heating element heating heat isolation layer, thereby can reduce the power consumption of wearable equipment battery.
Referring to fig. 2, a schematic structural diagram of a core body temperature measurement device according to an embodiment of the present application is shown in fig. 2, where the core body temperature measurement device includes: a control module 201, a blood oxygen measurement module 202 and a core body temperature measurement module 203. Wherein, the blood oxygen measuring module 202 and the core body temperature measuring module 203 are respectively connected with the control module 201.
Referring to fig. 3, which is a schematic structural diagram of a core body temperature measuring module 203 in a core body temperature measuring device according to an embodiment of the present application, as shown in fig. 3, the core body temperature measuring module 203 includes: a first temperature collection unit 301, a second temperature collection unit 302, a medium unit 303, and an auxiliary heating unit 304. The first temperature acquisition unit 301, the second temperature acquisition unit 302 and the auxiliary heating unit 304 are respectively in contact connection with the medium unit 303.
Specifically, the first temperature acquisition unit 301 is used for acquiring the skin temperature of the measured object, the second temperature acquisition unit 302 is used for acquiring the temperature of the medium unit 303, and the auxiliary heating unit 304 is used for heating the medium unit 303.
The dielectric material of the dielectric unit 303 may be a light-weight insulating material, such as foamed polyethylene, and is not limited in this respect. The auxiliary heating unit 304 may be formed of an electric heating element such as a heating wire, an electric heating plate, etc., and is not particularly limited herein.
Referring to fig. 4, a schematic structural diagram of another core body temperature measuring device provided in the present embodiment is shown in fig. 4, in which the blood oxygen measuring module 202 is in contact with the core body temperature measuring module 203, and meanwhile, the blood oxygen measuring module 202 may also be used to heat the medium unit 303.
Further, please refer to fig. 5, which is a schematic diagram illustrating a core body temperature measuring device according to an embodiment of the present application, and as shown in fig. 5, the control module 201 is configured to receive a first acquisition temperature acquired by the first temperature acquisition unit 301 and a second acquisition temperature acquired by the second temperature acquisition unit 302, and determine the core body temperature of the object according to the acquired first acquisition temperature and the acquired second acquisition temperature.
When the core body temperature is measured by using the zero heat flow method, the auxiliary heating unit 304 is needed to heat the medium unit 303 so as to compensate the heat dissipated by the medium unit; when blood oxygen is measured, two paths of LEDs with different wavelengths are needed, the LEDs serve as light emitting components, heat is generated inevitably in the using process, the ambient temperature is increased due to the heat, the wavelengths of the LEDs can be changed greatly, and therefore collection and calculation of blood oxygen are affected, and scattering of the LEDs needs to be accelerated.
If the two methods are combined, the blood oxygen and the core body temperature are measured, and the heat generated in the blood oxygen measuring process can be used as a heat source in the zero-heat-flow body temperature measuring method, so that the heat dissipation speed of the blood oxygen measuring method is improved, the heat energy generated in the place where the heat source is needed is saved, and the utilization rate of the battery is improved.
Therefore, in the embodiment of the present application, by combining the blood oxygen measuring module 202 and the core body temperature measuring module 203, both blood oxygen can be measured, and the core body temperature can be measured, meanwhile, since the auxiliary heating unit 304 heats the medium unit 303, and simultaneously, the blood oxygen measuring module 202 is also used for heating the medium unit 303, thereby not only improving the heat dissipation speed of the blood oxygen measuring module 202, but also providing heat for the medium unit 303 in the core body temperature measuring module 203, and further reducing the heat required by the heating of the auxiliary heating unit 304, and therefore, the power consumption of the wearable device using the zero heat flow method to measure the core body temperature can be reduced.
Optionally, the blood oxygen measuring module 202 includes a transmitting LED and a receiving Photodiode (PD), wherein the transmitting LED may include a red LED and an infrared LED.
Specifically, in the process of measuring blood oxygen, the red light LED is used for emitting red light, the infrared LED is used for emitting infrared light, the red light emitted by the red light LED and the infrared light emitted by the infrared LED are received by the receiving PD through subcutaneous diffuse scattering, and the blood oxygen value is calculated after amplification and sampling. While the emitting LED emits light, the heat it generates may be used to heat the media element 303.
Optionally, the larger the size of the dielectric material used in the dielectric unit 303 is, the larger the specific heat capacity is, the more heat is required for heating, and by designing a reasonable size of the dielectric material and selecting a suitable dielectric material, and appropriately setting the distance between the emitting LED and the dielectric material, the heat generated by the LED can be utilized as much as possible, so as to reduce the energy required by the auxiliary heating unit 304 for heating.
Assuming that the mass of the dielectric material is m, the specific heat is C, the amount of heat generation of the auxiliary heating unit 304 is Q1, the amount of heat dissipation of the dielectric unit 303 is Q2, and the amount of heat generation of the emitting LED is Qled, the following equilibrium relationship can be obtained:
Qled+Q1＝mC△T+Q2 (1)，
where Δ T is the temperature of the auxiliary heating unit 304 for additionally raising the medium unit 303, it can be seen from formula (1) that if the medium unit 303 is not heated by using the emitting LED, the heating value Q1 of the auxiliary heating unit 304 will increase. Please refer to fig. 6, which is a schematic diagram of a first collecting temperature and a second collecting temperature of the core body temperature measuring device according to the embodiment of the present application, as shown in fig. 6, in the case that the blood oxygen measuring module 202 is used to heat the core body temperature measuring module 203 and the blood oxygen measuring module 202 is not used to heat the core body temperature measuring module 203, the auxiliary heating unit 304 additionally increases the temperature Δ T of the medium unit 303, as can be seen from fig. 6, the embodiment of the present application has the function of saving energy.
Optionally, referring to fig. 5, the core body temperature measurement module 203 further includes an analog-to-digital conversion module, and the analog-to-digital conversion module is respectively connected to the control module 201, the first temperature acquisition unit 301, and the second temperature acquisition unit 302.
Specifically, the analog-to-digital conversion module is configured to convert an analog temperature signal acquired by the first temperature acquisition unit 301 into a digital signal and send the digital signal to the control module 201, and convert an analog temperature signal acquired by the second temperature acquisition unit 302 into a digital signal and send the digital signal to the control module 201.
The analog conversion module is composed of an analog-to-digital converter, i.e. an a/D converter, or ADC for short, which generally refers to an electronic component for converting an analog signal into a digital signal. A typical ADC converts an input analog signal into an output digital signal. Because the temperature signal that temperature sensor gathered is analog signal, consequently, can adopt ADC to convert the analog temperature signal who gathers into digital signal so that control module handles.
Optionally, referring to fig. 5, the core body temperature measurement module 203 may further include a control unit, the control unit is connected to the control module 201 and the auxiliary heating unit 304, and the control unit is configured to receive a heating instruction sent by the control module 201 and control the auxiliary heating unit 304 to perform heating according to the heating instruction. For example, the control unit may be a switch button on the auxiliary heating unit 304, when the switch button receives a heating instruction sent by the control module 201, the auxiliary heating unit 304 is started to perform heating, meanwhile, the ADC module continuously obtains a first collection temperature collected by the first temperature collection unit 301 and a second collection temperature collected by the second temperature collection unit 302, and sends the first collection temperature and the second collection temperature to the control module 201, the control module 201 controls whether the control unit continues to heat the auxiliary heating unit 304 according to the received first collection temperature and the received second collection temperature, and if not, the control unit stops heating the auxiliary heating unit 304.
It should be noted that fig. 5 illustrates a case where the core body temperature measurement module 203 includes both the control unit and the ADC module, and it should be understood that the core body temperature measurement module 203 may also include only one of the control unit and the ADC module.

It should be noted that, the modules mentioned in the embodiments of the methods are the modules described in the core body temperature measuring device, and for convenience of description, the reference numerals are omitted.

step S701 receives a first collection temperature and a second collection temperature.
The first acquisition temperature is obtained by acquiring the skin temperature of the measured object by a first temperature acquisition unit in the core body temperature measurement module, and the second acquisition temperature is obtained by acquiring the temperature of the medium unit by a second temperature acquisition unit in the core body temperature measurement module. The first temperature acquisition unit and the second temperature acquisition unit may be contact temperature sensors or non-contact temperature sensors, and are not limited in this respect.
Step S702, determining the core body temperature of the object according to the first and second acquisition temperatures.
According to the core body temperature measuring method provided by the embodiment of the application, the core body temperature of the measured object is determined according to the received first acquisition temperature acquired by acquiring the skin temperature of the measured object through the first temperature acquisition unit and the second acquisition temperature acquired by acquiring the temperature of the medium unit through the second acquisition temperature acquisition unit. In the above steps, the core body temperature of the measured object is determined by simultaneously acquiring the skin temperature and the temperature of the medium unit without directly acquiring the skin temperature of the measured object by using the temperature acquisition unit, so that the measured core body temperature is more accurate, and the energy consumption of the battery of the wearable device for measuring the core body temperature by using the zero heat flow method is reduced.
Please refer to fig. 8, which is a schematic flowchart of another core body temperature measurement method according to an embodiment of the present application, and as shown in fig. 8, the step S702 includes:
step S801, comparing the first collection temperature and the second collection temperature to obtain a temperature difference value.
Because the first collection temperature is the skin temperature of the measured object, and the second collection temperature is the temperature of the medium unit, it can be understood that, in the initial state, the medium unit is not heated by any heat source, therefore, the first collection temperature is greater than the second collection temperature, and a certain temperature difference value exists between the first collection temperature and the second collection temperature. Along with emission LED in the blood oxygen measurement module constantly works, emission LED can continuously give off the heat, because emission LED is connected with the medium unit contact, consequently, the heat that emission LED gived off can heat the medium unit, along with the continuous rise of medium unit temperature, the second acquisition temperature constantly rises, then, the temperature difference value between first acquisition temperature and the second acquisition temperature can constantly reduce. Because the heat that the emission LED gived off in the course of the work is limited, when the heat that gives off of emission LED, after being absorbed by the medium unit completely, the temperature of medium unit will no longer change, and at this moment, the temperature difference value of first collection temperature and second collection temperature can not change again.
Step S802, controlling an auxiliary heating unit in the core body temperature measuring module to perform heating according to the temperature difference value.
By judging the temperature difference value between the first collection temperature and the second collection temperature, if the difference value is not zero, the auxiliary heating unit is controlled to perform heating.
Because auxiliary heating unit and medium unit contact are connected, at the in-process that auxiliary heating unit constantly heated, medium unit's temperature constantly rises, then, the second is gathered the temperature and is constantly risen, and at this moment, the temperature difference value between first collection temperature and the second collection temperature constantly reduces.
Meanwhile, the control module continuously acquires a first acquisition temperature acquired by the first temperature acquisition unit and a second acquisition temperature acquired by the second temperature acquisition unit through the ADC module arranged in the core body temperature measurement module, and judges whether the auxiliary heating unit continues to heat according to a temperature difference value between the received first acquisition temperature and the received second acquisition temperature.
And step S803, determining whether the first collection temperature and the second collection temperature are the same, and if so, controlling the auxiliary heating unit to stop heating.
If the first collection temperature is the same as the second collection temperature, namely when the temperature difference value does not exist between the first collection temperature and the second collection temperature, the auxiliary heating unit is controlled to stop heating.
And step S804, taking the first acquisition temperature with the same temperature as the core body temperature of the object to be measured.
And when the first acquisition temperature is the same as the second acquisition temperature, taking the first acquisition temperature or the second acquisition temperature as the core body temperature of the object to be measured.
Optionally, the auxiliary heating unit in the core body temperature measurement module is controlled to perform heating, and a heating instruction may be sent to the core body temperature measurement module, where the heating instruction is used to instruct the auxiliary heating unit in the core body temperature measurement module to start heating.
Specifically, the core body temperature measurement module may include a control unit, and thus, the auxiliary heating unit may be controlled by the control unit to perform heating. For example, the control unit may be a switch button on the auxiliary heating unit, and when the switch button receives a heating instruction sent by the control module, the auxiliary heating unit is started to perform heating; when the switch button receives a heating stopping instruction sent by the control module, the auxiliary heating unit stops heating.
Please refer to fig. 9, which is a schematic flowchart of another core body temperature measurement method according to an embodiment of the present application. As shown in fig. 9, the blood oxygen collecting module starts to operate to heat the medium unit, and at this time, the auxiliary heating unit does not operate. Along with blood oxygen collection module constantly works, give the heating of medium unit, first collection temperature and second collection temperature form the stable difference in temperature. The ADC module collects two paths of temperatures for judgment, if the second collection temperature is smaller than the first collection temperature, the auxiliary heating unit starts heating and continuously circulates until the second collection temperature is equal to the first collection temperature, and the first collection temperature or the second collection temperature is measured and serves as the core body temperature of the object to be measured.
