Abstract
The interaction between a filling valve (28) on the filling device and an adapter valve on a bottle adapter has improved anesthetics filling features including radially inwardly directed bars (26), which engage (pass into) corresponding slots on the outlet pipe of the bottle adapter. The bars engaged in the slots actuate the adapter valve. The bars are provided on the inner wall of a filler neck (22).
Claims15
A filling system for an anesthetic evaporator, the filling system comprising
- a bottle adapter for being connected to a storage container for liquid anesthetic, said bottle adapter having an adapter neck and an outlet pipe with a slot extending in a longitudinal direction of said bottle adapter;
- an adapter valve on said outlet pipe of said bottle adapter, said adapter valve having an actuating surface with said adapter valve being brought from a closed position into an open position via said actuating surface;
- a first anesthetic-specific coding on said adapter neck;
- a filling device for filling anesthetic at the anesthetic evaporator, said filling device having a filler neck for receiving said adapter neck;
- a filling valve with a valve plate in said filling device, said valve plate being brought from a closed position into an open position by said outlet pipe of said bottle adapter;
- a second anesthetic-specific coding on said filler neck, said second anesthetic-specific coding having a design corresponding to said first anesthetic-specific coding;
- and
- a bar extending from the inner wall of said filler neck at a right angle to a direction of flow of the anesthetic, said bar engaging said slot to be caused to engage said actuating surface of said adapter valve by pressing said bottle adapter relative to said filling device.
A filling system for an anesthetic evaporator, the filling system comprising:
- a bottle adapter having an adapter neck and an adapter pipe with a slot extending in the longitudinal direction;
- an adapter valve on said adapter pipe, said adapter valve being brought from a closed position into an open position via an actuating surface in the area of said slot;
- a filling device on the anesthetic evaporator with a filler neck for receiving said adapter neck and with a filling valve;
- and
- a bar attached to said filler neck and extending radially toward a center thereof, said bar engaging said slot and engaging said actuating surface of said adapter valve.
An anesthetic filling system comprising:
- a storage container containing anesthetic and having an adapter neck with a connected adapter pipe and with radial slots having a depth extending in the longitudinal direction of the adapter pipe;
- anesthetic evaporator having an anesthetic reservoir and a filling device for filling said reservoir, said filling device having a filler neck for receiving said adapter neck;
- an adapter valve connected to said outlet pipe, said adapter valve having an actuating surface in the area of said slots, said adapter valve being brought from a closed position into an open position via movement of said actuating surface;
- a filling valve connected to said filling device;
- and
- a radially extending bars attached to said filler neck, said bars extending into respective said slots and engaging said actuating surface of said adapter valve for actuating said adapter valve.
