How does an autoclave work?Figure 2 Example Cycle TapePrintout, Showing the threephases of the process.Autoclaves are commonly used in healthcare settings to sterilize medical devices. Prior to this date, pressure was the sole indication of control with no means to verify temperature or air elimination.Over time, new autoclave technology has been developed including pre-vacuum cycles in 1958, and steam-flush pressure-pulse in 1987 allowing the science to evolve into the autoclaves, or steam sterilizers, used in hospitals today.
He demonstrated the greater power of penetration exhibited by moist heat (steam) compared to dry heat.įinally, in 1933 modern autoclave technology was introduced with the first pressure steam sterilizer that controlled performance by measuring the temperature in the chamber drain line (thermostatic trap). ANSI/AAMI 4, which provide standards and guidelines for the processing of medical devices, refers to autoclaves for healthcare specifically as Steam Sterilizers.Who invented the autoclave machine?Figure 1 the first steam sterilizer builtin 1880 by Charles ChamberlandThe steam digester, a prototype of the autoclave that is better known now as a pressure cooker, was invented by French-born physicist Denis Papin in 1679.ġ It wasn't until 1879 that the French microbiologist Charles Chamberland created a new version called the autoclave to be used in medical applications.The science of disinfection and sterilization began in 1881 with the research of Robert Koch on the disinfecting properties of steam and hot air. The moisture in the steam efficiently transfers heat to the items to destroy the protein structure of the bacteria and spores.In healthcare, the term 'autoclave' is typically used as the nomenclature to describe a Steam Sterilizer. The items are heated to an appropriate sterilization temperature for a given amount of time.
An autoclave is a machine that uses steam under pressure to kill harmful bacteria, viruses, fungi, and spores on items that are placed inside a pressure vessel.
