The utility model data analysis terminal data calculates Main Basiss：
The form that body metabolism produces heat mainly has radiation, convection current and evaporation.The surface temperature of heat loss through radiation and skin
It is related with environment temperature.Temperature in use sensor measure skin surface temperature, combining environmental temperature, according to Stefan-
Bohzmann rules can obtain the heat of radiation exchange：
In formula：R is the spacious heat of radiation；δ is radiation coefficient；S is swept area；TsFor body surface absolute temperature；TEIt is exhausted for environment
To temperature.
Under certain condition, heat loss through convection is equally related with the surface temperature and environment temperature of skin.Exchange heat using newton
The quantity of heat convection, can be expressed as by formula：
C=hc(tw-tf)
In formula：C foot the quantity of heat convection；hcFor convection transfer rate；twFor shell temperature；tfFor environment temperature.
Evaporative heat loss is related with skin surface evaporation capacity.Here consider that human skin surface seems drying, without sweat
Cause the situation of moistening.At this moment in recessive (or referred to as skin diffusion) state of perspiring, caused latent heat losses E tables
Show.Fan Geer thinks that skin diffusion controls from Models of Human Thermal Regulation in this case, can be expressed as：
E=rm (Psk-Pα)
In formula：E is the spacious heat of evaporation；R is the latent heat of vaporization of water；M is skin permeability coefficient；PskFor the sky under skin temperature
The saturation partial pressure of vapor in gas；PαFor ambient water vapor partial pressure.
After temperature is contacted less than the metallic conductor of shell temperature with body surface, to be led since there are temperature difference, body surface with metal
Heat transfer can be produced between body, so that shell temperature changes.The temperature at metallic conductor both ends can also change, it becomes
Change amount is dependent on the amount of heat transfer from body surface to metallic conductor.And the amount of heat transfer of body surface to metallic conductor depends on capillary
In velocity of blood flow.Therefore, by measuring the temperature change at metallic conductor both ends, it is possible to calculate velocity of blood flow.
The beneficial effects of the utility model are：It is simple in structure, manufacture it is of low cost, easy to operate, easy to carry, can pass through
Skin surface temperature realizes quick, the accurate measurement of velocity of blood flow.
