Medical infrared thermometer and measurement compensating method of medical infrared thermometer

Abstract

The invention discloses a medical infrared thermometer and a measurement compensating method of the medical infrared thermometer. The medical infrared thermometer is composed of an infrared temperature measurement module, an ultrasound distance measurement module, a power module and a signal processing unit. The infrared temperature measurement module is a TN9 infrared temperature measurement module and can output the target temperature and the environment temperature, the ultrasound distance measurement module, the signal processing unit and the infrared temperature measurement module are packaged in a shell, the power module is packaged on the lower portion of a handle, and the handle and the shell are integrally designed. The measurement compensating method of the medical infrared thermometer includes the steps of adopting a multivariate linear regression method to analyze and process test data, building a model of relations among a measuring distance, the environment temperature and the human body temperature to be measured, and using software programming to achieve human body temperature measurement compensation. According to the medical infrared thermometer and the measurement compensating method of the medical infrared thermometer, measuring errors are limited between -0.13 DEG C and 0.11 DEG C, good linearity and good reversibility are achieved, the measurement accuracy is high, the requirement for accurately measuring the temperature of the human body can be met, and the medical infrared thermometer and the measurement compensating method are suitable for clinical diagnosis.

Description

technical field [0001] The invention relates to a medical thermometer, in particular to a non-contact infrared thermometer and a measurement compensation method thereof, which belongs to the technical field of testing and is mainly used for clinical body temperature detection. Background technique [0002] In recent years, human and animal epidemics such as SARS, influenza A, and bird flu have frequently broken out, and people's attention to public safety has continued to increase. Body temperature is one of the important indicators to characterize the health of the human body. Accurate measurement of body temperature can quickly isolate suspected patients and avoid large-scale outbreaks of the epidemic. [0003] Common human body temperature measurement methods are mainly divided into two categories, namely contact and non-contact. The most common contact measurement is to use mercury thermometers to measure human body temperature, such as underarms, oral cavity, etc. The ...

Problems solved by technology

For example, the utility model patent (CN203042220U) and related products are easily affected by the measurement distance and ambient temperature, and the measurement error is often above 1.0°C. It can only be used to roughly judge the human body condition, and cannot meet the requirements of rapid and accurate body temperature measurement for clinical diagnosis.
