Ear thermometer with ear canal sensing device and measuring method thereof

Abstract

The invention provides an ear thermometer with an ear canal sensing device and a measuring method thereof. The ear thermometer mainly comprises two sensors: a proximity sensor and an infrared sensor, wherein, the proximity sensor is arranged on a probe for judging whether the probe is in a status of being inserted in an ear canal, and the proximity sensor is taken as the ear canal sensing device for automatically switching a measuring mode into an ear temperature mode or a second mode such as a forehead temperature mode, a surface temperature mode or a room temperature mode; the infrared sensor is used for measuring temperature; and after the proximity sensor judges the measuring mode, the infrared sensor measures temperature, a control module processes a signal of the proximity sensor and displays the measuring mode and a temperature measuring result on a display unit. In the invention, the proximity sensor is used for judging whether the probe is inserted in the ear canal to switch the measuring mode, and more than two temperature measuring modes can be combined in one machine.

Description

technical field [0001] The invention relates to an infrared ear thermometer, in particular to an ear canal detector using a proximity sensor. The product can automatically judge and switch the measurement mode to the ear temperature mode or the second measurement mode, and the second measurement mode can be forehead temperature mode, surface temperature mode or room temperature mode. Background technique [0002] Measuring body temperature is an important step in medical treatment to determine whether there is a fever. Body temperature measurement is divided into axillary temperature, ear temperature, forehead temperature, sublingual temperature, anal temperature, etc., of which axillary temperature, sublingual temperature, anal temperature The temperature is measured with a mercury thermometer or an electronic thermometer; the ear thermometer uses infrared measurement technology, and the probe is inserted into the ear canal to quickly measure the ear temperature, and after ...

AI Technical Summary

Problems solved by technology

[0003] Since both ear thermometers and forehead thermometers use infrared measurement technology, only the measurement parts are different, so there are already two-in-one thermometers on the market that combine ear temperature and forehead temperature, but in order to match different measurement parts, Its emissivity is different from the mouth temperature compensation value, so all current two-in-one thermometers must be operated manually by the user. ...
