Description

Technical Field

[0001] The present application relates to the technical field of medical equipment, and in particular to a core body temperature measurement device, method and electronic equipment. Background Art

[0002] Blood oxygen saturation and body temperature are two important indicators that reflect the physiological function state of the human body.

[0003] Blood oxygen saturation is referred to as blood oxygen. In clinical practice, a blood oximeter is used to measure blood oxygen. A typical blood oximeter is equipped with two light emitting diodes (LEDs) of different wavelengths to illuminate the area containing arterial blood vessels. Since blood with different oxygen content has different absorption rates for light of different wavelengths, the blood oxygen saturation is measured based on this characteristic.

[0004] Body temperature, in clinical practice, generally refers to the core body temperature of the human body. In the prior art, the zero heat flow method is generally used to measure the core body temperature of the human body. When the zero heat flow method is used to measure the core body temperature, a heating device is required to heat the thermal isolation layer to compensate for the heat dissipated. After a period of feedback heating control, the thermal balance is established, resulting in a zero heat flow state. At this time, the measured epidermal temperature is the core body temperature.

[0005] However, when using the zero heat flow method to measure core body temperature, the heating device generally requires an additional high-energy heat source.

[0051] To make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. It should be understood that the drawings in the present application only serve the purpose of explanation and description and are not used to limit the scope of protection of the present application.

In addition, those skilled in the art can add one or more other operations to the flowchart under the guidance of the content of the present application, or remove one or more operations from the flowchart.

[0052] In addition, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0053] It should be noted that the term "comprising" will be used in the embodiments of the present application to indicate the existence of the features declared thereafter, but does not exclude the addition of other features.

[0054] Human body temperature is a barometer of physical health. Effectively monitoring human body temperature has become an important topic. The body temperature referred to clinically refers to the average core body temperature. In people's daily lives, the temperatures of the armpits, mouth and forehead are generally measured. These temperatures are strictly speaking body surface temperatures, which have a certain error from the core body temperature. At present, the commonly used method to accurately measure the core body temperature of the human body is the zero heat flow method. The schematic diagram of the principle of measuring core body temperature by the zero heat flow method is shown below. Figure 1 shown.

[0055] See also Figure 1 , where the temperature sensor a is used to measure the body surface temperature, and the thermal isolation layer is used to prevent heat from being lost from the human body to the external environment. Ideally, the thermal isolation layer can achieve a complete thermal insulation effect, so that all the heat conducted from the deep body is retained on the body surface. When the thermal equilibrium is finally reached, the body surface temperature under the thermal isolation layer will be the same as the core body temperature, which is called "zero heat flow".

[0056] When zero heat flow is reached, the temperature measured by temperature sensor a can be regarded as the core body temperature. However, since absolutely heat-insulating materials do not exist in reality, a comparator, a heating device and a temperature sensor b are introduced to complete the measurement together. The comparator determines whether the heating device is working by judging the values ​​collected by the two temperature sensors. The heating device is used to heat the thermal insulation layer to compensate for the lost heat, so that the temperature of the thermal insulation layer measured by temperature sensor b is consistent with the body surface temperature measured by temperature sensor a, forming a state of zero heat flow. After a period of feedback heating control, thermal equilibrium is established, and the temperature finally measured by temperature sensor a is regarded as the core body temperature.

[0057] From the above process, it can be seen that when the zero heat flow method is used to measure core body temperature, an active heating device is required to form a corresponding zero heat flow channel. However, on wearable devices powered by batteries, using batteries to provide energy for heating devices is a huge energy load. Therefore, on wearable devices that use the zero heat flow method to measure core body temperature, the existing use of additional heating devices to heat the thermal isolation layer will cause a significant increase in the power consumption of the batteries on these devices.

[0058] Based on the above problems, the present application proposes a core body temperature measurement device, which can measure both blood oxygen and core body temperature by combining a blood oxygen measurement module and a core body temperature measurement module. Moreover, since not only an auxiliary heating unit is used to heat the thermal isolation layer, but also the blood oxygen measurement module is used to heat the thermal isolation layer, the energy required for the auxiliary heating unit to heat the thermal isolation layer is reduced, thereby reducing the power consumption of the wearable device battery.

[0059] See also Figure 2 , is a schematic diagram of the structure of a core body temperature measurement device provided in an embodiment of the present application, such as Figure 2 As shown, 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. The blood oxygen measurement module 202 and the core body temperature measurement module 203 are connected to the control module 201 respectively.

[0060] See also Figure 3 , is a schematic diagram of the structure of a core body temperature measurement module 203 in a core body temperature measurement device provided in an embodiment of the present application, such as Figure 3 As shown, the core body temperature measurement module 203 includes: a first temperature acquisition unit 301, a second temperature acquisition 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 with the medium unit 303.

[0061] Specifically, the first temperature collection unit 301 is used to collect the skin temperature of the object being measured, the second temperature collection unit 302 is used to collect the temperature of the medium unit 303 , and the auxiliary heating unit 304 is used to heat the medium unit 303 .

[0062] The dielectric material of the dielectric unit 303 may be a light insulating material, such as foamed polyethylene, which is not specifically limited here. The auxiliary heating unit 304 may be composed of electric heating elements such as electric heating wires, electric heating wires, and electric heating plates, which are not specifically limited here.

[0063] See also Figure 4 , a schematic diagram of the structure of another core body temperature measurement device provided in an embodiment of the present application, such as Figure 4As shown, the blood oxygen measurement module 202 is in contact with the core body temperature measurement module 203 , and the blood oxygen measurement module 202 can also be used to heat the medium unit 303 .

[0064] For further information, see Figure 5 , is a schematic diagram of the principle of a core body temperature measurement device provided in an embodiment of the present application, such as Figure 5 As shown, the control module 201 is used to receive the first collected temperature collected by the first temperature collection unit 301 and the second collected temperature collected by the second temperature collection unit 302, and determine the core body temperature of the object under test according to the collected first collected temperature and the second collected temperature.

[0065] When the zero heat flow method is used to measure the core body temperature, the auxiliary heating unit 304 is required to heat the medium unit 303 to compensate for the heat dissipated; and when measuring blood oxygen, two LEDs with different wavelengths are required. As a light-emitting component, the LED will inevitably generate heat during use. The heat will cause the ambient temperature to rise, which will greatly change the wavelength of the LED, thereby affecting the collection and calculation of blood oxygen. Therefore, it is necessary to accelerate the scattering of the LED.

[0066] If the above two methods are combined to measure both blood oxygen and core body temperature, the heat generated in the process of measuring blood oxygen can be used as the heat source in the zero heat flow body temperature measurement method, thereby improving the heat dissipation speed of the former and saving the energy to generate heat for the latter where a heat source is needed, thereby improving the utilization rate of the battery.

[0067] Therefore, in the embodiment of the present application, by combining the blood oxygen measurement module 202 and the core body temperature measurement module 203, both blood oxygen and core body temperature can be measured. At the same time, since the auxiliary heating unit 304 heats the medium unit 303, the blood oxygen measurement module 202 is also used to heat the medium unit 303, thereby improving the heat dissipation speed of the blood oxygen measurement module 202 and providing heat for the medium unit 303 in the core body temperature measurement module 203, thereby reducing the heat required for heating the auxiliary heating unit 304, and thus reducing the power consumption of the wearable device that uses the zero heat flow method to measure the core body temperature.

[0068] Optionally, the blood oxygen measurement module 202 includes a transmitting LED and a receiving photodiode (PD), wherein the transmitting LED may include a red LED and an infrared LED.

[0069] Specifically, in the process of measuring blood oxygen, the red LED is used to emit red light, and the infrared LED is used to emit infrared light. The red light emitted by the red LED and the infrared light emitted by the infrared LED are diffusely scattered under the skin and received by the receiving PD. After amplification and sampling, the blood oxygen value is calculated. While the emitting LED emits light, the heat generated by it can be used to heat the medium unit 303.

[0070] Optionally, the larger the size of the dielectric material used in the dielectric unit 303 and the larger the specific heat capacity, the more heat is required for heating. By designing a reasonable size of the dielectric material, 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 and the energy required for heating by the auxiliary heating unit 304 can be reduced.

[0071] Assuming that the mass of the dielectric material is m, the specific heat is C, the heat generated by the auxiliary heating unit 304 is Q1, the heat dissipated by the dielectric unit 303 is Q2, and the heat generated by the emitting LED is Qled, the following balance relationship can be achieved:

[0072] Qled+Q1=mC△T+Q2 (1),

[0073] Wherein, ΔT is the temperature of the dielectric unit 303 that is additionally raised by the auxiliary heating unit 304. It can be seen from formula (1) that if the emitting LED is not used to heat the dielectric unit 303, the heat Q1 of the auxiliary heating unit 304 will increase. Figure 6 , is a schematic diagram of a first collection temperature and a second collection temperature of a core body temperature measurement device provided in an embodiment of the present application, such as Figure 6 As shown, when the blood oxygen measurement module 202 is used to heat the core body temperature measurement module 203 and when the blood oxygen measurement module 202 is not used to heat the core body temperature measurement module 203, the temperature △T that the auxiliary heating unit 304 additionally raises for the medium unit 303 is determined by Figure 6 It can be seen that the embodiment of the present application has the function of saving energy.

[0074] Optional, see Figure 5 The core body temperature measurement module 203 also includes an analog-to-digital conversion module, which is connected to the control module 201, the first temperature acquisition unit 301 and the second temperature acquisition unit 302 respectively.

[0075] Specifically, the analog-to-digital conversion module is used to convert the analog temperature signal collected by the first temperature collection unit 301 into a digital signal and send it to the control module 201 , and to convert the analog temperature signal collected by the second temperature collection unit 302 into a digital signal and send it to the control module 201 .

[0076] Among them, the analog conversion module is composed of an analog-to-digital converter, which is an A / D converter, or ADC for short, which usually refers to an electronic component that converts an analog signal into a digital signal. The usual ADC converts an input analog signal into an output digital signal. Since the temperature signal collected by the temperature sensor is an analog signal, the ADC can be used to convert the collected analog temperature signal into a digital signal for processing by the control module.

[0077] Optional, see Figure 5 The core body temperature measurement module 203 may also include a control unit, which is connected to the control module 201 and the auxiliary heating unit 304 respectively. The control unit is used to receive the 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 the heating instruction sent by the control module 201, the auxiliary heating unit 304 is started to perform heating. At the same time, the ADC module continuously obtains the first acquisition temperature collected by the first temperature acquisition unit 301 and the second acquisition temperature collected by the second temperature acquisition unit 302, and sends them to the control module 201. The control module 201 controls the control unit to continue to heat the auxiliary heating unit 304 according to the received first acquisition temperature and second acquisition temperature. If not, the control unit is controlled to stop heating the auxiliary heating unit 304.

[0078] It should be noted that the above Figure 5 What is shown in FIG. 2 is a case where the core body temperature measurement module 203 includes both a control unit and an ADC module. 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.

[0079] Next, the specific embodiments of the core body temperature measurement method provided by the present application will be described in detail. It should be noted that the modules mentioned in these method embodiments are the modules described in the core body temperature measurement device above, and the reference numerals are omitted for ease of description.

[0080] See also Figure 7 , is a flow chart of a core body temperature measurement method provided in an embodiment of the present application, the execution subject of the method is the control module in the above core body temperature measurement device, such as Figure 7 As shown, the method includes:

[0081] Step S701, receiving a first collected temperature and a second collected temperature.

[0082] The first collected temperature is obtained by collecting the skin temperature of the measured object by the first temperature collection unit in the core body temperature measurement module, and the second collected temperature is obtained by collecting the temperature of the medium unit by the second temperature collection unit in the core body temperature measurement module. The first temperature collection unit and the second temperature collection unit can be contact temperature sensors or non-contact sensors, which are not specifically limited here.

[0083] Step S702: determining the core body temperature of the subject according to the first collected temperature and the second collected temperature.

[0084] The embodiment of the present application provides a core body temperature measurement method, which determines the core body temperature of the object under test according to the first collected temperature obtained by collecting the skin temperature of the object under test by the first temperature collection unit, and the second collected temperature obtained by collecting the temperature of the medium unit by the second temperature collection unit. In the above steps, the core body temperature of the object under test is determined by the skin temperature and the temperature of the medium unit at the same time by collecting the skin temperature and the temperature of the medium unit, and the core body temperature of the object under test is not directly obtained by using the temperature collection unit to collect the skin temperature of the object under test. Therefore, the measured core body temperature is more accurate, and the energy consumption of the battery of the wearable device that uses the zero heat flow method to measure the core body temperature is reduced.

[0085] See also Figure 8 , is a flow chart of another core body temperature measurement method provided in an embodiment of the present application, such as Figure 8 As shown, the above step S702 includes:

[0086] Step S801: compare the first collected temperature and the second collected temperature to obtain a temperature difference value.

[0087] Since the first acquisition temperature acquires the epidermal temperature of the object being measured, and the second acquisition temperature acquires 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 acquisition temperature is greater than the second acquisition temperature, and there is a certain temperature difference between the two. As the emitting LED in the blood oxygen measurement module continues to work, the emitting LED will continue to emit heat. Since the emitting LED is in contact with the medium unit, the heat emitted by the emitting LED will heat the medium unit. As the temperature of the medium unit continues to rise, the second acquisition temperature continues to rise, and the temperature difference between the first acquisition temperature and the second acquisition temperature will continue to decrease. Since the heat emitted by the emitting LED during operation is limited, when the heat emitted by the emitting LED is completely absorbed by the medium unit, the temperature of the medium unit will no longer change. At this time, the temperature difference between the first acquisition temperature and the second acquisition temperature will no longer change.

[0088] Step S802: According to the temperature difference value, the auxiliary heating unit in the core body temperature measurement module is controlled to perform heating.

[0089] By judging the temperature difference between the first collected temperature and the second collected temperature, if the difference is not zero, the auxiliary heating unit is controlled to perform heating.

[0090] Since the auxiliary heating unit is in contact with the medium unit, the temperature of the medium unit rises continuously during the continuous heating of the auxiliary heating unit, and the second collection temperature rises continuously. At this time, the temperature difference between the first collection temperature and the second collection temperature decreases continuously.

[0091] At the same time, the control module continuously obtains the first collection temperature collected by the first temperature collection unit and the second collection temperature collected by the second temperature collection unit through the ADC module set in the core body temperature measurement module, and determines whether the auxiliary heating unit continues to heat according to the temperature difference value between the received first collection temperature and the received second collection temperature.

[0092] 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.

[0093] If the first collected temperature and the second collected temperature are the same, that is, when there is no temperature difference between the first collected temperature and the second collected temperature, the auxiliary heating unit is controlled to stop heating.

[0094] Step S804: taking the first collected temperature when the temperatures are the same as each other as the core body temperature of the subject.

[0095] When the first collected temperature and the second collected temperature are the same, the first collected temperature or the second collected temperature at this time is used as the core body temperature of the measured object.

[0096] Optionally, controlling the auxiliary heating unit in the core body temperature measurement module to perform heating may include sending a heating instruction to the core body temperature measurement module, wherein the heating instruction is used to instruct the auxiliary heating unit in the core body temperature measurement module to start heating.

[0097] Specifically, the core body temperature measurement module may include a control unit, and thus, the auxiliary heating unit may be controlled to perform heating by controlling the control unit. 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 stop heating instruction sent by the control module, the auxiliary heating unit stops heating.

[0098] See also Fig. 9, is a flowchart diagram of another core body temperature measurement method provided in an embodiment of the present application. Fig. 9 As shown, the blood oxygen collection module starts to work and heats the medium unit. At this time, the auxiliary heating unit does not work. As the blood oxygen collection module continues to work and heats the medium unit, a stable temperature difference is formed between the first collection temperature and the second collection temperature. The ADC module collects two temperatures for judgment. If the second collection temperature is lower than the first collection temperature, the auxiliary heating unit starts heating and continues to cycle until the second collection temperature is equal to the first collection temperature. The first collection temperature or the second collection temperature is measured as the core body temperature of the object to be measured.

[0099] It is worth mentioning that Fig. 9 The specific implementation details have been described in detail in the above embodiments and will not be repeated here.

[0100] Based on the same inventive concept, the embodiment of the present application also provides a core body temperature measurement device corresponding to the core body temperature measurement method. Since the principle of solving the problem by the device in the embodiment of the present application is similar to the above-mentioned core body temperature measurement method in the embodiment of the present application, the implementation of the device can refer to the implementation of the method, and the repeated parts will not be repeated.
