Part of a collection of medical technologies donated to the Canada Science and Technology Museums Corporation by the Canadian Anesthesiologists’ Society.

Fonction

Used to deliver anesthetic gas mixture of oxygen and cyclopropane. Used primarily for induction, short anesthesias, and dental anesthesia. This device was recommended for procedures of short duration, including dental and outpatient procedures. The unit could also be used as a resuscitator by fitting it with cylinders of oxygen alone.

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)
