Abstract
A system for delivery of volatile liquid drugs as supplied to a patient by an anaesthetic vaporizer comprises a supply container (2) and a vaporizer (32) which includes a sump. Each of the supply container and the vaporizer is provided with a valve assembly (6, 34) which, when closed, prevent passage of fluid from the supply container into the sump. The supply container and the sump are connected to one another by means of a bayonet connection, which is made when indexing elements on the containers correspond. The valve assemblies in the containers are opened when the containers are connected to one another by means of an insert (40) located within an inlet conduit (10) linking the two containers. The inlet conduit (10) is rotatable between lowered and raised positions, to open a valve (37) by which flow of fluid into and out of a reservoir for fluid in the sump can be controlled.
