Description : The pressure cooker is a large aluminum pot with a lid. Both the pot and lid have two black plastic handles on opposite sides. A small hollow pipe is attached to the lid. A pressure gauge dial is also attached to the lid. This dial has a black face with white numbers indicating the pressure. A metal needle shows the pressure inside the pot. A circular rack sits in the bottom of the pot. On top of the rack fits a circular steamer tray in a wire steamer rack.
Commentaires : Josephine Gibbons, a Registered Nurse, used this pressure cooker to sterilize medical equipment. She was appointed to the Order of Canada in 1992 and passed away in 1995. Not all microorganisms can be destroyed at temperatures of 100 degrees Celsius, and thus simply boiling medical instruments does not completely sterilize them. Higher temperatures are needed, and a pressure cooker allows these higher temperatures to be reached. To sterilize medical instruments with a pressure cooker, one would have placed the items to be sterilized in the cooker's steamer tray, well above water level so that only steam touched the instruments. The instruments needed to be slightly separated from each other, allowing steam to circulate around all items. Items to be sterilized needed to be cooked under full pressure for a specified amount of time. The minimum time required was 15 minutes for surface sterilization of items like needles and tweezers, and 30 minutes for deep sterilization of items like gauze. The items were then left to cool and dry before use. The idea of boiling water under pressure to increase the boiling temperature, resulting in faster cooking times for food, was developed around 1680 by French physicist Denis Papin. Pressure cookers became common cooking items throughout the nineteenth century, and in the twentieth century, cast aluminum replaced iron in some models, like this one.
Fonctions : This pressure cooker was used for sterilizing tools for medical use. The vent on the top of the lid allows air and steam to escape from the pot when it is open.
