Embodiment 1

[0059] Referring to Fig. 6, it is an embodiment of the body core temperature measuring device of the present invention, the device is provided with a measuring disc 14 with a binding belt 1, the binding belt is made of soft cloth, and there is an elastic material 6 and a locking device on it 7 to ensure the tightness of the human body. A heat insulating material layer 2 is provided on the measuring plate 14, and a body surface temperature sensor 3 is installed on the inner side of it close to the human skin, and an ambient temperature sensor 4 and an electric heating element 5 connected to the battery are embedded in the outer heat insulating material layer. The disk is in the shape of a cuboid, with a size of 40*40*15mm3 (length*width*height), and a weight of 10g. The electric heating element 5 is a micro electric heating soft sheet of 35*35*1mm, embedded in the heat insulating material. The micro-heater and the body surface temperature sensor 3 are isolated by a heat insulat...

Embodiment 2

[0061] This example is an embodiment of the method for measuring the body core temperature of the present invention. The device described in Example 1 is fixed on the human body to estimate the body core temperature. The specific process is as follows:

[0062] 1. Bind the measuring device to the measuring site and stabilize for 30 minutes;

[0063] 2. Use the micro-heating element 5 to simulate the temperature rise ΔTeh of the environment, and after 20 minutes of stabilization, detect the skin temperature change as ΔTsh, then you can get:

[0064] Individual correction coefficient: A=Rc / Re=ΔTsh / (ΔTeh-ΔTsh)

[0065] Ambient temperature correction coefficient: α=ΔTsh / ΔTeh

[0066] 3. After stopping the heating, record the skin temperature Ts and the ambient temperature Te at a certain moment, and measure the body core temperature (rectum or armpit) with an electronic thermometer and record them, respectively recording them as Tso, Teo, and Tco as reference points;

[0067] 4....

Embodiment 3

[0083] This example is another embodiment of the body core temperature measurement method of the present invention

[0084] The difference between this method and Example 2 is that the estimation method of body core temperature in the fourth step is different. In this example, the individualized correction coefficient A, the ambient temperature correction coefficient α, and Tso, Teo, and Tco of the reference point are obtained in this example. Finally, estimate the body core temperature Tc according to the following formula:

[0085] Steady state quantity estimation:

[0086] Tc 稳 =Tco+(dTs-α×dTe) / (1-α) (4)

[0087] Transient estimation:

[0088] Tc 瞬 =A×Re×Cs×(dTs-α×dTe) / dt (5)

[0089] Then the estimated body core temperature is: Tc=Tc 稳 +Tc 瞬

[0090] In the formula

[0091] Tc is the estimated value of the core temperature of the human body

[0092] Cs is the heat capacity of the insulating material layer

[0093] Ts is the real-time measured human body surface ...

Description

technical field [0001] The invention belongs to a method and a device for obtaining dynamic physiological parameters of a human body, in particular to a method and a device for measuring a non-invasive body core temperature, a calibration device for the device and a calibration method thereof. Background technique [0002] The dynamic variability of human body core temperature contains extremely rich information of thermoregulation system and is an important vital sign. It can be used as an intermediate parameter to provide reference for comprehensive diagnosis of various human diseases. There are two types of continuous and dynamic measurement of body core temperature: invasive and non-invasive. The invasive method will cause certain damage to the human body. For occasions that require long-term continuous monitoring, the invasive method is very inconvenient. Non-invasive body temperature measurement methods include thermal insulation method, zero heat flow method, etc. Th...
