Intelligent ear thermometer

Abstract

The invention provides an intelligent ear thermometer. The ear thermometer comprises an ear thermometer body, and the ear thermometer body comprises a main body, an ear thermometer PCBA main control board and a sensing head. The sensing head is fixed at the top end of the main body; the ear thermometer PCBA main control board is arranged in the main body and is electrically connected with the sensing head; and a digital display screen and a function detection key are arranged on the main body. The intelligent ear thermometer also comprises a heating base for preheating the sensing head, the heating base comprises a shell, an inserting groove is formed in the top end of the shell and is matched with the sensing head, and a heating assembly is arranged on the outer ring of the inserting groove and is used for heating the sensing head in the inserting groove at a constant temperature. According to the intelligent ear thermometer provided by the invention, an external heating device is adopted to heat the sensing head at a constant temperature, the measurement accuracy in any environment is ensured, the REID module is arranged on the heating base to read and collect measurement information and send the measurement information to a hospital computer system, informatization management is achieved, the operation time of medical staff is shortened, and the data arrangement and collection efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of ear thermometers, in particular to an intelligent preheatable ear thermometer. Background technique [0002] The ear thermometer is a contact-sensing temperature measuring instrument. It uses the heat of the ear cavity tympanic membrane to transfer electromagnetic translation motion (the ear cavity tympanic membrane is close to the inferior colliculus, which is in line with clinical science) to convert the voltage value to calculate the measured patient temperature. According to radiation theory, the different temperatures generated by objects diverge outward in the way of electromagnetic translation, which are received and converted into voltage by a precise infrared sensor (Thermopile), and then the readings are converted by a microcomputer to reveal it. When the sensor head of the existing ear thermometer is used in a low temperature environment, the sensor head that handles the low temperature will quickly...

AI Technical Summary

Problems solved by technology

When the sensor head of the existing ear thermometer is used in a low temperature environment, the sensor head that handles the low temperature will quickly reduce the temperature in the ear cavity. This physical phenomenon is the main reason for the relatively low temperature of the measurement failure, resulting in low fever in patients. It cannot be detected, so we advocate the invention of an intelligent ear thermometer with constant temperature heating. The existing heating ear thermometer (Braun, Germany) adopts an integrated structure with a built-in heating plate, which directly heats the sensor head. The defect is The use of ultra-low temperature consumes a lot of power, which requires a battery with a larger capacity. The size of the battery will affect the size of the ear thermometer. Using a large-capacity battery will directly cause the ear thermometer to be bulky and inconvenient to use; the power consumption of a small-capacity battery Not enough so it cannot be used when the ambient temperature is below 16°C
