Active fixed-distance non-contact high-precision medical thermometer and temperature measurement method thereof

Abstract

The invention discloses an active fixed-distance non-contact high-precision medical thermometer and a temperature measurement method thereof. The thermometer comprises a gun shell, and an MCU processor is arranged in the gun shell. A thermopile sensor and a distance sensor are arranged at a muzzle at the front end of the gun shell; a liquid crystal display screen and an operation panel are arranged on the rear side of the gun shell; and a thermistor and a heating component connected with the thermistor are arranged in the gun shell. A matching module is arranged on the MCU processor; a temperature and humidity sensor is arranged on one side edge of the gun shell; and a buzzer is arranged at the top portion of the gun shell. The temperature measuring method comprises the steps that the thermometer is aligned with aforehead, measurement can be automatically started within a set distance, a measured temperature value and a measured distance value are matched with the matching module to beamplified or reduced, and then a real body temperature value is obtained and displayed on the liquid crystal display screen. The measured temperature error is smaller than 0.1 DEG C, the thermometeris slightly influenced by the environment temperature and humidity, and the problem that the environment temperature and humidity have errors on measurement is solved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to an active fixed-distance non-contact high-precision medical thermometer and a temperature measuring method thereof. Background technique [0002] Existing precise medical temperature measurement technologies include mercury thermometers, electronic thermometers, ear thermometers, and forehead thermometers; each has its own advantages and disadvantages. Mercury thermometers have been used to measure body temperature for a long time. It is recommended to eliminate mercury thermometers all over the world by 2025. Although electronic thermometers and ear thermometers are acceptable, they are all contact measurements. They need to be disinfected or use disposable products every time they are used, which is prone to cross-contamination; The measurement method of the forehead thermometer is related to the environment and distance. In actual tests, different data are often obta...

Problems solved by technology

For this reason, an object of the present invention is to propose an active fixed-distance non-contact high-precision medical thermometer and temperature measurement method thereof. The measurement distance changes, the measurement temperature error is less than 0.1°C, and the thermometer is minimally affected by the ambient temperature and humidity, which solves the problem that the ambient temperature causes errors in the measurement
