How does a clinical thermometer work?

How does a clinical thermometer work?

Working Principle: The thermometer is thoroughly shaken before measuring the temperature of the body. Then the mercury level drops and remains inside the bulb. In this condition, if the thermometer is placed under the tongue or under the arms, the temperature and consequently the volume of the thermometer increases.

How are clinical thermometers used in points?

The thermometer is to be placed under the tongue inside the mouth of the patient to obtain the temperature of the body. When the reading is taken, the thermometer needs to be held vertical to the eyes and the eyes must be at level with the top of the mercury in the capillary thread.

What is a clinical thermometer why it is used?

A clinical thermometer is a thermometer used to measure human body temperature. Most made in the 20th century are mercury-in-glass thermometers. They are accurate and sensitive, having a narrow place where the mercury level rises very fast. A kink in the tube stops the mercury level from falling on its own.

What are the features of a clinical thermometer?

A clinical thermometer usually consists of a cylindrical bulb with mercury and a capillary tube is finely fixed to this setup. The two major features of a clinical thermometer are its calibration as well as its constriction. We know that the temperature of the human body varies from 95∘F to 110∘F.

What are the features of clinical thermometer?

How is a clinical thermometer used in medicine?

Clinical thermometers, also known as medical thermometers or doctors’ thermometers, are used to take body temperatures in humans and animals2. Many newer thermometers use infrared radiation to record temperature at alternative points, such as the eardrum or forehead2.

What kind of thermometer can you use other than the human body?

Since clinical thermometers can’t be used to measure temperature other than the human body, we need a special type of thermometers for other purposes. A laboratory thermometer, which is colloquially known as the lab thermometer, is used for measuring temperatures other than the human body temperature. It ranges from -10˚C to 110˚C.

How is a digital thermometer used to measure temperature?

Digital Thermometer These thermometers are used for measuring the temperature by the means of an electronic circuit. The information captured is sent to a microchip that processes it and gets displayed numerically on the digital screen. They are easy to use, inexpensive, and accurate.

Who is considered to be the father of the thermometer?

Daniel Gabriel Fahrenheit is considered to be the father of thermometer. He was a German physicist who dedicated his life to science and inventions. The modern mercury thermometer was invented by Fahrenheit. He is also credited for the invention of the mercury-in-glass thermometer.
