The size of thermometers remained a major disadvantage. Santorio S. In: Commentaria in Primam Fen Primam Libri Canonis Avicenna. A large step forward was achieved by Santorio (Sanctorio Sanctorius) who invented a mouth thermometer.

He produced a classic textbook Systems of Medicine, in eight volumes (1896–99), and the excellent Notes on the composition of scientific papers, 1904.

Aitkin in 1852 made a mercury instrument with a narrower tube sited above a bulb reservoir; this ensured that the mercury did not drop back after the reading had been taken. But his contemporaries were unimpressed, and the thermometer was not widely used. A primarily clinical trial has been undertaken to investigate and compare the use of mercury and digital thermometers in a ward situation. It replaced a foot‐long model, which required 20 minutes to determine a patient's temperature. Conventionally, temperature is measured orally, rectally or under the armpit. Clinical Thermometer. Gabriel Daniel Fahrenheit based his new scale on a mixture of ice and ammonium chloride as the lower point. He published Diseases of the Arteries, Including Angina Pectoris (1915) and a text on Greek Medicine in Rome (1921). He wrote De statica medicina (1614; tr. This Feature Is Available To Subscribers Only. In the time of Hippocrates, only the hand was used to detect the heat or cold of the human body, although fever and chills were known as signs of morbid processes. Both laboratory and clinical studies show that there is no significant difference in the average accuracy of the two types of thermometers, however there is a greater fluctuation of readings of temperature when using electronic thermometers. Oxford University Press is a department of the University of Oxford. In 1665, Christiaan Huygens added a scale extending from the freezing point to the boiling point of water, the original centigrade system. In Alexandrine medicine, the pulse was observed as an index of disease, superseding the crude assessment of temperature. But none is wholly free of problems. Van Swieten (1700–72), founder of the Viennese School of Medicine, Anton De Haen (1704–76), and separately George Martine,2 started to use the thermometer at the bedside. He was also a noted medical historian. 1737). Clinical thermometers are meant for clinical purposes. The normal human body temperature is 37˚C; which can fluctuate between the ranges 35˚C to 42˚C. He established a range of normal temperature from 36.3 to 37.5 °C. It replaced a foot‐long model, which required 20 minutes to determine a patient's temperature. For 28 years, Allbutt practised in Leeds, performing invaluable clinical studies, mainly of arterial and nervous disorders. It is a long narrow glass tube with a bulb containing mercury at the end. It furthers the University's objective of excellence in research, scholarship, and education by publishing worldwide, This PDF is available to Subscribers Only. In 1868, Carl Wunderlich3 published temperature recordings from over 1 million readings in over 25000 patients made with a foot‐long thermometer used in the axilla. Pearce, A brief history of the clinical thermometer, QJM: An International Journal of Medicine, Volume 95, Issue 4, April 2002, Pages 251–252, Clinical thermometers, also known as medical thermometers or doctors' thermometers, are used to take body temperatures in humans and animals 1 2. The measurement of temperature soon became an inescapable routine. He found mercury more useful than water, as it expanded and contracted more rapidly. It was left to Thomas Clifford Allbutt (1836–1925) to design in 1866 a conveniently portable 6‐inch clinical thermometer,4 able to record a temperature in 5 min. In the Middle Ages, the four humours were assigned the qualities of hot, cold, dry and moist, and thus fever again acquired importance. Of the many tools and instruments regarded as essential to the clinical examination, none has had such widespread application as the clinical thermometer. De Haen studied diurnal changes in normal subjects and observed changes in temperature with shivering or fever, and he noted the acceleration of the pulse when temperature was raised. From 1892 until the end of his career, he was Regius Professor of Physics in the University of Cambridge. Santorio (1561–1636) was an Italian physiologist, professor at Padua. He described his inventions in 1625.1 Sanctorio Sanctorius produced several designs, but all were cumbersome and required a long time to measure the oral temperature. Cited and illustrated by Lyons AS, Petrucelli RJ. He made quantitative experiments in temperature, respiration, and weight, and measured ‘insensible perspiration’ that laid the foundation for the study of metabolism. 5th ed. It is developed for measuring the human body temperature. Traditional thermometers use thermometric liquids (i.e., alcohol, mercury) to measure temperature in body cavities -- orally, rectally, vaginally -- or at other axillary points, such as the underarm 1 2. Well, a clinical thermometer measures temperature of the human body. To this day, the time to get an accurate, stable reading remains difficult. It was left to Thomas Clifford Allbutt (1836–1925) to design in 1866 a conveniently portable 6‐inch clinical thermometer, 4 able to record a temperature in 5 min. In 1742, the Swedish astronomer Anders Celsius reintroduced the centigrade scale into practice, but despite improvements in design of the thermometer, its use remained largely neglected until the late 19th century. In 1871, he published a monograph outlining the use of the ophthalmoscope. Temperatures outside this range suggested disease. He was knighted in 1907. Galileo in 1592 devised a crude temperature‐measuring instrument, but it had no scale and therefore no numerical readings; further, it was affected by atmospheric pressure. Recent advances in thermometer design include digital, electronic direct and predictive, infra‐red ear thermometers, and dot‐matrix or phase‐change thermometers. Here are two extremely cool thermometers that have come up in recent times. Glass thermometers must remain in contact with sublingual tissue for 8 min. 1625. J.M.S. However, the thermometer was not in generally use until Hermann Boerhaave (1668–1738), with his students Gerard L.B. A medical thermometer (also called clinical thermometer) is used for measuring human or animal body temperature.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 Rectal temperature takes 5 min, axillary temperatures up to 11 min.
