A safety arrangement for filling and emptying an anesthetic vaporizer via a supply vessel connected thereto includes a movable tube-shaped conducting member having first and second ends. A vessel-connecting piece is provided on its first end and an index member is provided on its second end for engaging a vaporizer. The tubular-shaped conducting member has a ventilating channel separate from the filling channel and the safety arrangement is improved with respect to its use characteristics. This improvement is obtained in that a joint piece is connected to the second end of the tubular conducting member intended for the vaporizer. An index member is rotatably journalled in the joint piece and contains respective line segments of the filling channel and the ventilating channel.

Safety arrangement for filling and emptying an anesthetic vaporizer having an inlet means for supplying anesthetic medium and relieving gas to and from said vaporizer, said anesthetic medium contained within a supply vessel, the safety arrangement comprising: a movable tubular conducting member having first and second ends and including structure defining a first ventilating channel segment and a first filling channel segment separated from said ventilating channel segment; vessel connecting means provided on said first end for detachably connecting the supply vessel to said tubular conducting member; a joint member having two end portions defining respective axes conjointly defining an angle therebetween less than 180°and one of said end portions being connected to said second end of said tubular conducting member; an index member adapted to be inserted into said inlet means for communicating with the vaporizer and defining a longitudinal axis, said index member including means for preventing said index member from rotating with respect to the vaporizer when inserted into said inlet means and having structure defining a second ventilating channel segment and a second filling channel segment; journalling means formed in the other one of said end portions of said joint member for rotatably journalling said joint member on said index member so as to permit said joint member and said conducting member to conjointly rotate about said longitudinal axis to swing the supply vessel from a location beneath said longitudinal axis to a location above said longitudinal axis thereby causing the contents of the vessel to flow from the latter and down through said first filling channel and then through said filling passage means to said second filling channel; and, said joint member including ventilating passage means for interconnecting said first and second ventilating channel segments and filling passage means for interconnecting said first and second filling channel segments irrespective of the angular position of said index member relative to said joint member.
