Ear thermometer with pre-heating function

Abstract

The invention relates to the technical field of ear thermometers, and particularly relates to an ear thermometer with a preheating function. The ear thermometer comprises a shell, wherein left and right outer walls of the shell are integrally sleeved with sleeves in an inclined leftward way; sleeve rods are fixed inside the sleeves in a sleeving manner; the sleeves and the sleeve rods are in screwjoint and are fixed through locking bolts and isometric corresponding threaded holes; curved sustaining plates are integrally arranged at tail ends of the sleeve rods; a temperature-measurement probeis arranged on the left end part of the shell in a left-right telescopic manner; a supporting plate is integrally fixed on the right end part of the temperature-measurement probe, and the measurementsafety is high; and the sleeve joint depth between the sleeves and the sleeve rods can be conveniently adjusted by means of the locking bolts and the plurality of threaded holes which are in corresponding screw joint, the sustaining plates at the tail ends of the sleeve rods can be supported against two positions outside ears, and the situation that the ear canal of a tested person is accidentally injured due to the tampering head of the tested person or the shaking hand of an operator can be reduced.

Description

technical field [0001] The invention relates to the technical field of ear thermometers, in particular to an ear thermometer with a preheating function. Background technique [0002] Infrared thermoelectric ear thermometers can measure temperature by irradiating the eardrum, but due to the characteristics of infrared radiation measurement, the probe of the thermometer is at different ambient temperatures each time the measurement is performed, and the temperature error range of the measurement fluctuates greatly, resulting in the measurement results Inaccurate, affecting the doctor's diagnosis. [0003] In this regard, the patent application number CN201620857399.X proposes an ear thermometer with heating function, which includes a power supply device, a controller, a temperature measuring probe, a temperature detection sensor electrically connected to the controller, a temperature compensation device and Relay; the temperature detection sensor and the temperature compensat...

AI Technical Summary

Problems solved by technology

[0005] 1. The measurement safety is poor. The above scheme lacks a safety protection structure. It is easy to accidentally injure the tester's ear canal when the head of the testee is shaking or the operator's hand is shaking unsteadily. At the same time, it cannot be tested Quick observation and treatment of the ear feces in the ear canal, which may easily lead to the possibility that the ear feces will continue to be pushed forward by the temperature measuring probe;

[0006] 2. The test accuracy is low. The length of the temperature measuring probe in the above scheme is fixed, and it is not convenient to slowly advance and adjust the position of the temperature measuring probe as needed, resulting in poor temperature measurement accuracy of the temperature measuring probe
