Method and device for measuring core body temperature of livestock

Abstract

The invention relates to the field of animal breeding and animal medicine, and provides a method and a device for measuring the core body temperature of livestock. According to the measuring method, in accordance with a physiological structure of the measured livestock, a temperature sensor is coupled with the body surface close to the core body temperature, a heat flux conduction formula is utilized, the temperature gradient of artificial materials can be calculated through heat resistance, the heat resistance of a measured position of body tissues is derived, and the core body temperature is deduced in an inversion way through the measured body surface temperature. Before the long-time use, the correction is carried out through measured values of the rectal temperature. The device comprises a heat transfer layer, an outside heat insulation layer and three temperature sensors, wherein the heat conductivity and the thickness of the heat transfer layer are known, the temperature measuring parameters of the three temperature sensors are very close through tests, and the temperature sensors are used for respectively measuring the surface temperature of the skin coupling position, the surface temperature outside the heat transfer layer and the surface temperature outside the heat insulation layer. When the method and the device provided by the invention are used, the long-period, continuous and dynamic core body temperature measurement on the livestock can be realized.

Description

technical field [0001] The invention relates to the fields of animal breeding and animal medicine. In particular, the present invention relates to the continuous measurement of core body temperature of livestock. The invention has more general application to measuring physiological parameters related to health monitoring, medical diagnosis and medical applications. Background technique [0002] The metabolism and vital activities of the animal body are closely related to the body temperature. In other words, body temperature affects the life of animals. The normal body temperature of animals is affected by various factors such as season, day and night, environmental temperature and behavior, and fluctuates within a certain range. [0003] The temperature of the body can be divided into two levels, the core and the outer shell, which refer to the deep tissue and superficial tissue in the functional sense respectively. The temperature of the deep tissues of the body is cal...

AI Technical Summary

Problems solved by technology

[0008] To sum up, the method of measuring the core body temperature of animals often needs to be carried out in specific physiological parts such as the mouth, rectum, and ear canal, which is very unsuitable for long-term body temperature monitoring; while the measurement based on body surface temperature is easier to solve the measurement site problem, but so far there has been no public literature to clarify the relationship model between body surface temperature and core body temperature, and it is difficult to reflect the real core body temperature through the measurement of body surface temperature
