Abstract
An anesthetic vaporizer has a receiving part devised for connection to a collar-equipped bottle, the receiving part having a locking device for locking/unlocking the bottle. Improved connection is achieved by providing the receiving part with a tubular section with a tube wall and an internal cavity, with a through opening arranged in the tube wall enabling the bottle's collar to move past the opening when the bottle is attached to the receiving part. The opening extends down at an angle to the center line of the tubular section, and the locking device has a resilient locking element partially arranged in the opening. The resilient locking element is devised to assume, in a passive state, a first position inside the internal cavity preventing the unimpeded passage of the bottle's collar and, when acted upon, to move downwards-outwards in the opening to a second position in the cavity allowing the unimpeded passage of the bottle's collar, and an opening arrangement is disposed, when actuated, to act on the resilient locking element.
