Abstract
An interlock system for use with two or more vaporizers when mounted in plug-in fashion on the back bar of an anaesthesia machine includes a spacer 22 of generally channel shaped section having spaced arms 10, 11 engageable by pins which extend outwardly from individual vaporizers when a concentration dial on the vaporizer is moved from an off position to an operative position. Outward movement of the pins causes the spacer to slide on the back bar between adjacent units thereby preventing outward movement of a pin on a similar adjacent unit.
