ANAESTHETIC GAS FILLING DEVICE

摘要

Transfer device for transferring an anaesthetic from a storage bottle (6) to a container (1) by means of an adapter (20). The adapter (20) is provided with a bore (22) for cooperating with a connection cylinder (7) of the storage bottle (6). There is also an opening element (40) positioned in the bore (22) and provided with outer threads (42) for cooperating with inner threads (17) in connection with the cylinder (7). By screwing-down the connection cylinder (7) into the bore (22) the lower actuator surface (19) of the connection cylinder cooperates with pins (33) of a one-way valve (28) in the adapter (20) and opens the one-way valve. Thereafter a projecting pin (43) on the opening element (40) cooperates with an actuator member (12) positioned within the connection cyclinder (7) and opens a one-way valve (8) in the storage bottle (6). In this way the contents of the storage bottle (6) is transferred to a container (1) via the adapter (20). The one-way valve (28) in the adapter is opened before the one-way valve (8) in the storage bottle (6).
