Abstract
The invention relates to a connecting mechanism for connecting a vessel (5) through the intermediary of a connecting element (3) to a liquid container (6) of an anaesthetic liquid vaporizing apparatus (1), the connecting element including two ducts (23, 24) extending therethrough, the anaesthetic liquid being carried along one (23) of said ducts between vessel (5) and liquid container (6) and the gas displaced by the liquid being carried along the other duct (24) between vessel and liquid container in the direction opposite to that of the liquid, and the connecting mechanism including an attachment point (2) for fixing said connecting element (3) and a transmission element (10) for operating a shut-off device (13), the shut-off device being capable of closing or opening a flow communication between vessel (5) and the liquid container. Transmission element (10) can be in at least three different positions, one of the positions being the one in which the transmission element lies prior to the linking of a connecting element to a connecting mechanism, and one of the positions being the one to which the transmission element shifts automatically as a result of the linking procedure of a connecting element, and one of the positions being the one in which the transmission element lies after the opening of a flow communication controlled by shut-off device (13) between vessel and liquid container. The invention relates also to a method for connecting a vessel (5) through the intermediary of a connecting element (3) to a connecting mechanism and thereby to a liquid container (6).
