Abstract
A system of making a connection between the yoke of an anesthetic delivery apparatus and a gas cylinder for supplying a gas to that apparatus. The system includes an adaptor block that has a keying system, such as pegs, that keys the adapter block into a specific gas cylinder, such as by indentations. The adapter block has machine readable indicia and is affixed to the anaesthesia delivery apparatus such that the apparatus can read the indicia to determine the position of the adaptor block and thus identify the particular gas cylinder that is connected to the adapter block. By this system, a plurality of gas cylinders having differing gases can be used to supply a single inlet of an anesthetic delivery apparatus rather than have a separate inlet for each gas. In each instance, the particular gas thus provided is identified by the anaesthetic delivery apparatus to make the necessary adjustments to that apparatus to administer the gas to a patient.
