ABSTRACT:
A receiving arrangement is disclosed for filling an anaesthetic medium from a supply vessel into the charging chamber of an anaesthetic apparatus. The supply vessel is connectable to the arrangement by means of a coupling piece. The arrangement includes a receiving structure having an input opening for receiving the coupling piece therein and a connecting part disposed adjacent the receiving structure. The connecting part includes channels communicating with the charging chamber for conducting the anaesthetic medium to the latter. A closure piece is slidably mounted in the receiving structure to slide between a first position opposite the ports and a second position whereat the closure piece is displaced away from the ports. A resilient biasing spring biases the closure piece into the first position. A drive moves the receiving structure between a rest location whereat the closure piece seals the ports with respect to the ambient and an actuating location whereat the receiving structure and the closure piece are displaced away from the ports. The receiving structure can now receive the coupling piece thereby causing the closure piece to be displaced to its second position. The coupling piece and the connecting part conjointly define a connecting interface whereat the anaesthetic medium flows from the coupling piece into the channels when the structure is returned to the rest location with the coupling piece inserted therein. A blocking piece blocks the entry of the coupling piece through the opening when the receiving structure is in its rest location.
