Medical infrared forehead temperature instrument suitable for multiple environment temperatures and working method

Abstract

The invention belongs to the technical field of medical instruments, and particularly provides a medical infrared forehead thermometer suitable for multiple environment temperatures. The thermometer comprises a constant-temperature temperature measuring gun and a portable charging bracket, the constant-temperature temperature measuring gun comprises an upper shell, a handle is arranged on one side of the bottom of the upper shell, a temperature measuring switch is arranged at the handle, the back face of the upper shell is provided with a display screen, the front face of the upper shell is sequentially provided with an infrared transmitter and a receiver in the vertical direction, and the two sides of the upper shell are each provided with an installation cabin which is sunken inwards. By utilizing the characteristics of a cold end and a hot end of a semiconductor cold and hot sheet, a refrigerating area and a heating area which are mutually independent are arranged, air in the upper shell is circulated in the refrigerating area and the heating area through a circulating air pump, so that the internal temperature of the upper shell is controlled to be kept within the conventional working temperature range of the constant-temperature temperature measuring gun, the working temperature of the constant-temperature temperature measuring gun is expanded, and the constant-temperature temperature measuring gun can work in the environment of -10 DEG C to 45 DEG C from the conventional range of 16 DEG C to 35 DEG C.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a medical infrared forehead thermometer applicable to multiple ambient temperatures and a working method. Background technique [0002] Forehead temperature gun, also known as infrared thermometer, is mainly designed for measuring human body temperature, but it can also be used in other fields. It is widely used, easy to use, and can save a lot of time. The existing forehead The temperature gun is mainly composed of two main parts, the infrared probe and the receiver, to measure the temperature. [0003] The current epidemic situation in the world is relatively serious, and the regions and places of use of forehead thermometers are relatively wide. Due to the relatively large temperature differences between regions and places of use, the temperature range that the infrared probes of forehead thermometers can withstand is relatively small. , the minimum ambi...

Problems solved by technology

[0003] The current epidemic situation in the world is relatively serious, and the area and place of use of forehead thermometers are relatively wide. Due to the relatively large temperature differences between regions and places of use, the temperature range that the infrared probe of the forehead thermometer can withstand is relatively small. , the minimum ambient temperature requirement is basically higher than 16 degrees Celsius and lower than 36 degrees Celsius. Therefore, the performance of the infrared temperature measuring probe is easily limited when measuring temperature at low and high temperatures, resulting in the failure of the infrared probe to detect the temperature or cause the temperature to be detected. Inaccurate, which is not conducive to the promotion of hot or cold areas. Moreover, in northern China, the winter temperature is generally below zero. The infrared probe of the forehead thermometer is very easy to detect inaccurately, which brings difficulties to the daily temperature measurement of epidemic prevention and control. Large resistance, and most of the forehead temperature guns are rechargeable, and long-term outdoor work can easily cause power shortages. The above problems are still to be solved
