Ear thermometer capable of fast measuring and measuring method thereof

Abstract

The invention relates to an ear thermometer capable of fast measuring and a measuring method thereof. The ear thermometer comprises an infrared ear temperature detection unit, a control unit, a display unit and a signal conversion unit, wherein the control unit and the display unit are respectively connected with a microprocessor; the infrared ear temperature detection unit is connected with the microprocessor by the signal conversion unit; the microprocessor is also in connection with an ambient temperature detection unit; the ambient temperature detection unit periodically detects the temperature of the external environment and stores the temperature information of external environment in order to compensate for the influence of the temperature of the external environment on the ear temperature detected by the infrared ear temperature detection unit through the processing of the microprocessor. When in measurement, the ear thermometer does not need to separately measure the temperature of external environment again before measuring the ear temperature every time, thereby being capable of measuring the ear directly and continuously, greatly reducing the waiting time for each measurement clearance, effectively improving the efficiency of ear temperature measurement and being more beneficial to use.

Description

technical field [0001] The present invention relates to a body temperature measurement device and technology thereof, in particular to a rapid measurement ear thermometer and a measurement method thereof. Background technique [0002] The ear thermometer is a non-contact body temperature measurement device. Its measurement principle is based on the black body radiation theory. The infrared spectrum radiated by objects with different temperatures is different. By measuring the infrared spectrum radiated from the eardrum, the infrared ear temperature measurement unit is used. to measure the body temperature and convert it into a numerical value through the microcomputer and display it. The hypothalamus located in the hypothalamus of the human body is responsible for the task of regulating the heat generated by the human body and the heat emitted by the human body. It is the central point of the body temperature, and it is also the place where the body temperature rises first w...

Problems solved by technology

[0003] refer to figure 1 At present, when the ear thermometers on the market are working, each ear temperature measurement needs an interval of 3 to 10 seconds, that is, after each ear temperature measurement, in order to ensure the accuracy of the next measurement, the ear thermometer needs to be Clear the measured temperature in 3-10 seconds, return to the initial state, and re-measure the ambient temperature for the next measurement; It is necessary to use an ear thermometer for multiple consecutive measurements, and each measurement requires a waiting time of 3 to 10 seconds, which will inevitably affect the measurement efficiency if accumulated
