Abstract
One or more anesthetic vaporizers may be fluidly connected to the anesthetic delivery machine via a vaporizer mounting bar. The vaporizer mounting bar may include multiple vaporizer mounting positions. Each vaporizer includes interlock pins that extend when the vaporizer is opened and prevent the vaporizer from being opened when pushed in. When a first vaporizer is opened, its interlock pins may extend and cause the interlock pins of adjacent vaporizers, and vaporizers within a chain of interlock pin connections, to be pushed in, preventing the other vaporizers from being opened simultaneously with the first vaporizer. In various embodiments, a paddle system may translate the extension of an interlock pin from one vaporizer to the interlock pins of each of the other vaporizers in the direction of the extension, including the interlock pins of vaporizers in non-adjacent and non-chain positions.
