Fonction

Used as a container for soda lime in an anaesthetic mask.

Technique

In the early 1950s, Dr. Robert A. Hingson (1913-1996) became chairman of the Anesthesiology Department at Case Western Reserve University. Shortly thereafter he developed this field unit with engineers Frank Ziherl and Arthur Kish. Their objective was to create a safe, portable and simple device that could be used for resuscitation and administration of anesthetic gas mixtures with oxygen. They developed a nonexplosive gas mixture of 40% cyclopropane (the anesthetic), 30% helium and 30% oxygen, and packaged six liters of it into two miniature gas cylinders, each less than 3 inches long. The small gas cylinders and carbon dioxide (CO2) absorber made the device light and easy to carry. (ref.1) “It consists of the following parts: (1) a conductive rubber face mask; (2) a central axial body of spark-proof aluminum with a compression spring valve that may be opened and closed with a slight pressure, which opens the ports within the mask by sliding movement, permitting the exchange of respiratory gases within the unit; (3) a conductive breathing bag; (4) two right-arm aluminum containers to house the gas-filled cylinders; (5) gas cylinders; and (6) a soda lime canister. The aluminum containers attach with proximal threats to the small central axial body, which has a specially designed perforating and sealing sliding mechanism for perforating the oxygen and anesthetic cylinders. One of these side-arm containers has an orange band of colour to identify the anesthetic port, and the other side-arm container has a green band of color to designate the oxygen port.” (ref.2)
