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

Embodiment 1

[0035] see Figure 1-5 , the present invention provides a medical infrared forehead thermometer suitable for multiple ambient temperatures, including a constant temperature temperature measuring gun 1 and a portable charging bracket 6, the constant temperature temperature measuring gun 1 includes an upper casing 11, and the bottom side of the upper casing 11 is set There is a handle 13, a temperature measuring switch 14 is arranged at the handle 13, a display screen 17 is arranged on the back of the upper casing 11, an infrared emitter 16 and a receiver 15 are arranged vertically on the front of the upper casing 11, and the upper casing 11 The two sides of both sides are provided with the installation compartment 18 that is recessed inside, the opening of the installation compartment 18 is in the upper shell 11 and the ventilation cover 12 is clamped, and the circuit board 4 is arranged in the center of the upper shell 11, and the surface of the circuit board 4 is welded with ...

Embodiment 2

[0050] Such as Figure 6As shown, a working method of a medical infrared forehead thermometer suitable for multiple ambient temperatures includes the following steps:

[0051] Step S1, temperature control in a hot environment. When the constant temperature temperature measuring gun 1 is working in a high temperature environment, the internal temperature of the upper housing 11 is detected by the temperature sensor 3. When the internal temperature is greater than the maximum working temperature of the constant temperature temperature measuring gun 1, the temperature is passed. The sensor 3 sends a signal to the controller 5, and the controller 5 controls and starts the work of the semiconductor cold and hot sheet 28, and the cold source surface 281 and the heat source surface 282 produced by the semiconductor cold and hot sheet 28 make the cooling zone 181 and the cooling area 181 in the installation cabin 18. The hot zone 182 works at the same time, and the controller 5 contro...

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...
