Temp measurer of electronic clinical thermometer

Abstract

A temp. measurer of electronic clinic thermometer is composed of temp. measuring probe (thermosensitive semiconductor diode) and signal processing circuit. Its advantages are high speed and correctness, and the angle of temp. measuring probe variable between 30-90 deg..

Description

technical field [0001] The invention relates to an electronic thermometer. Background technique [0002] Mercury thermometers are currently the most commonly used body temperature measurement tools in hospitals and families in my country. Although mercury thermometers have factors such as inconvenient reading, long measurement time, and unsafe use, due to their small size, low cost, and no better products. long-term use instead. As we all know, mercury can evaporate into mercury vapor at room temperature, and humans and animals will suffer from mercury poisoning after inhalation. The production and use of these mercury products for many years will cause air and water pollution and seriously endanger the living environment of human beings. In recent years, with the advancement of medicine, the application of electronic technology has become more and more common. Medical devices combined with electronic technology have been widely used. Therefore, ele...

[0002] Mercury thermometer is currently the most commonly used body temperature measurement tool in hospitals and families in my country. Although mercury thermometers have factors such as inconvenient reading, long measurement time, and unsafe use, due to their small size, low cost, and no better products long-term use instead

As we all know, mercury can evaporate into mercury vapor at room temperature, and humans and animals will suffer from mercury poisoning after inhalation. The production and use of these mercury products for many years will cause pollution to the air and water quality, and seriously endanger the living environment of human beings.

In recent years, with the advancement of medicine, the application of electronic technology has become more and more common. Medical devices combined with electronic technology have been widely used. Therefore, electronic thermometers have appeared. The sensing heads of electronic thermometers have temperature-sensing elements. After processing with the resistance-capacitance oscillation method, the measured temperature is displayed on the liquid crystal display. However, due to the influence of factors such as the structure and the measurement environment, it takes a considerable amount of time from the start of the measurement to the completion of the measurement, which is inconvenient to use, especially Many infants and young children cannot tolerate long-term measurement and cause crying, which affects the measurement of body temperature

Another electronic thermometer, the ear thermometer, uses the principle of infrared temperature measurement for measurement, but it cannot be used in common people's homes because of its high price, and the infrared sensor cannot be aligned with the eardrum due to various reasons such as earwax and measurement angle. , resulting in measurement deviation
