A human body deep tissue temperature measuring instrument and measuring method

Abstract

The invention discloses a human body deep tissue temperature measuring instrument and a measuring method, comprising a temperature measuring probe for measuring body surface temperature and ambient temperature, a thickness measuring probe for measuring skin layer thickness and fat layer thickness, and data transmission unit, a display unit and a processing unit, the processing unit is respectively connected to the temperature measuring probe and the thickness measuring probe through the data transmission unit, and the processing unit is also connected to the display unit; The heat insulation layer is set outside the probe to avoid the influence of ambient temperature on the measured temperature, so that the measured human body surface temperature is more accurate; the thickness of the skin layer and the thickness of the fat layer are measured by the thickness measurement probe, and the temperature measurement probe measures the body surface temperature and ambient temperature , can quickly calculate the deep tissue temperature Tm with short time consumption and high accuracy.

Description

technical field [0001] The invention belongs to the technical field of tissue temperature measurement, and in particular relates to a human body deep tissue temperature measuring instrument and a measuring method. Background technique [0002] Existing studies have shown that the temperature of human deep diseased tissues (breast cancer, lymphosarcoma) is slightly higher than that of surrounding normal tissues, so we can use this characteristic to conduct a general survey of tumors and other diseases by measuring the temperature of human deep tissues. [0003] Such as figure 2 As shown, during the athlete's exercise, the temperature of the tissue at different depths of the athlete was measured by means of a thermocouple. The ambient temperature was a constant 22°C, the skin thickness was 1mm, and the initial muscle temperature was 37.5°C. The temperature of the athlete's exercise muscles rises by 1°C per minute. The ten curves in the figure from top to bottom are measured f...

Problems solved by technology

[0006] From this we can see that there is a certain relationship between the temperature of the deep tissue and the temperature of the body surface, but there are also differences between the temperature of tissues at different depths and the body surface; if the temperature of the deep tissue of the human body is directly measured by an infrared detector, the The accuracy of the results is not high; if the method of thermocouple is used to measure the temperature of deep tissue, although the accuracy of the measurement is improved, it takes a long time; The goal
