CONNECTION TO A GAS CYLINDER

摘要

A connection between the yoke (1) of anaesthetic delivery apparatus and a gas cylinder is made using an adaptor block (7) which has formations corresponding to formations on a gas cylinder containing a particular gas to allow the block and the cylinder to be connected to one another, and machine readable indicia (18) by which the block (7) can be identified by the delivery apparatus when connected to a cylinder of gas. The adaptor block (7) may include a plurality of sets of formations and indicia (11), to allow connections to a number of cylinders, containing different gases, to be made.
