  • Patent number: 4932398
    Abstract: An anaesthetic apparatus having a plurality of vaporizers is provided which utilizes an interlocking device which prevents more than one vaporizer from being activated at one time. The interlock device can be used with any number of vaporizers mounted side-by-side. The interlock device comprises a cam follower which is adapted to be received in a rotating cam which is used to activate the vaporizer. The cam follower is connected to a pair of cranks which activate bars which interact with bars on adjacent interlocking devices, when one of the interlocking devices is activated, thereby locking all the other vaporizers in a inoperative position. Also provided is a safety lock connector which is used for connecting hose to an anaesthesia apparatus.
