Medical thermometer
A medical thermometer or clinical thermometer is a device used for measuring the body temperature of a human or other animal. The tip of the thermometer is inserted into the mouth under the tongue (oral or sub-lingual temperature), under the armpit (axillary temperature), into the rectum via the anus (rectal temperature), into the ear (tympanic temperature), or on the forehead (temporal temperature).
The medical thermometer began as an instrument more appropriately called a water thermoscope, constructed by Galileo Galilei circa 1592–1593. It lacked an accurate scale with which to measure temperature and could be affected by changes in atmospheric pressure.
Santorio Santorio is the first known individual to have put a measurable scale on the thermoscope and wrote of it in 1625, though he possibly invented one as early as 1612. His models were bulky, impractical and took a fair amount of time to take an accurate oral reading of the patient's temperature.
Two individuals switched from water to alcohol in the thermometer.
Fahrenheit also created the temperature scale which is named after him, having recorded the system in 1724. The scale is still only mainly used for everyday applications in the United States, its territories and associated states (all served by the U.S. National Weather Service) as well as the Bahamas, Belize, and the Cayman Islands.
Christiaan Huygens created a clinical thermometer in 1665, to which he added an early form of the Celsius scale by setting the scale to the freezing and boiling points of water. By 1742 Swedish astronomer Anders Celsius created the Celsius temperature scale that was the reverse of the modern scale, in that 0 was the boiling point of water, while 100 was freezing. It was later reversed by Swedish botanist Carolus Linnaeus (1707–1778) in 1744.
Working independently of Celsius, Jean-Pierre Christin, permanent secretary of the Académie des sciences, belles-lettres et arts de LyonFR, developed a similar scale in which 0 represented the freezing point of water and 100 represented boiling. On 19 May 1743 he published the design of a mercury thermometer, the "Thermometer of Lyon" built by the craftsman Pierre Casati that used this scale.
The medical thermometer was used by Hermann Boerhaave, as well as his notable students Gerard van Swieten and Anton de Haen. It was also utilized around the same time by Scottish physician George Martine. De Haen made particular strides in medicine with the thermometer. By observing the correlation in a patient's change in temperature and the physical symptoms of the illness, he concluded that a record of one's temperature could inform the doctor of a patient's health. However, his proposals were not met with enthusiasm by his peers and the medical thermometer remained a scarcely used instrument in medicine.
