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 ...
Type B tympanogram may reveal (a) fluid in the middle ear, (b) perforation of the tympanic membrane or patent pressure equalization tube, or (c) a tumor in the middle ear. Type C tympanograms are consistent with negative pressure in the middle ear space resulting from compromised eustachian tube function and a retracted tympanic membrane.
Such thermometers are usually calibrated so that one can read the temperature simply by observing the level of the fluid in the thermometer. Another type of thermometer that is not really used much in practice, but is important from a theoretical standpoint, is the gas thermometer. Other important devices for measuring temperature include:
A medical thermometer showing a temperature reading of 38.7 °C (101.7 °F) Taking a human's temperature is an initial part of a full clinical examination. There are various types of medical thermometers, as well as sites used for measurement, including: In the rectum (rectal temperature) In the mouth (oral temperature)
If you suspect that you have a fever but don’t have a thermometer around (and don’t feel like investing in one), doctors say there are a few signs of a fever to look out for: You feel off .
An interesting method that involves direct manipulations on the tympanic membrane rather than relying on the acoustic reflex was proposed as one of the embodiments of a US patent by Ragauskas. [28] First, a measurement of the position of the tympanic membrane needs to be obtained while ICP is zero (denoted as the baseline position).
An otoscope enables viewing and examination of the ear canal and tympanic membrane (eardrum). [2] As the eardrum is the border between the external ear canal and the middle ear, its characteristics can indicate various diseases of the middle ear space.
Electrocochleography (abbreviated ECochG or ECOG) is a technique of recording electrical potentials generated in the inner ear and auditory nerve in response to sound stimulation, using an electrode placed in the ear canal or tympanic membrane. [1]
