Problems solved by technology
[0005] However, when the probe of the existing ear thermometer is in use, its temperature is usually quite different from the temperature of the human ear canal, which will affect the infrared radiation received by the infrared sensor from the eardrum, causing the probe to operate at different ambient temperatures. In this case, the measured temperature error range fluctuates greatly, resulting in inaccurate measurement results

Embodiment Construction
[0021] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings. It should be noted here that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation to the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0022] Such as figure 1 and figure 2 As shown, an ear thermometer with probe preheating function includes a gun body 1 and a probe 2 mounted on the gun body 1. The gun body 1 usually contains a PCBA board, a battery for power supply and a battery for operation control button;
[0023] The probe 2 includes a shell 3 made of a thermally conductive material. The thermally conductive material is metal, such as copper, aluminum, etc.; the front end of the shell 3 extends into the ea...

The invention discloses an ear thermometer with a probe preheating function, and belongs to the field of medical equipment. The ear thermometer comprises a gun body and a probe mounted on the gun body, the probe comprises a shell made of a heat conduction material, an electric heating wire is disposed in the shell, a mounting body is disposed in the shell, and a heat insulating layer is disposed between the mounting body and the shell; a working cavity is disposed in the mounting body, a high transmittance sheet, a waveguide and an infrared detector are disposed in the working cavity in sequence, and a cable passage connecting the working cavity and the gun body is further disposed in the mounting body. The ear thermometer disclosed by the invention not only can perform heating on the probe, but also can effectively prevent the temperature of the probe from interfering with the ear temperature measurement.
Description
Technical field [0001] The invention relates to the field of medical equipment, in particular to an ear thermometer with a probe preheating function. Background technique [0002] Ear temperature refers to the temperature of the eardrum. There is a hypothalamus in the deep part of the brain. Inside the hypothalamus, there is a "fixed point" structure for keeping the human body at a constant temperature. The hypothalamus is also the central point of human body temperature. The reason why the human body has a fever is the result of raising the body temperature after receiving the inflammatory chemicals circulating in the bloodstream at the "fixed point", so the hypothalamus is the first place where the body temperature rises. The blood flow of the supply eardrum and the supply of the hypothalamus coincides. Therefore, it is appropriate to use the eardrum temperature to reflect the temperature of the human body. Therefore, the eardrum is the first place to detect whether the human b...
