Patent ID: 7886783

Claim:
A system for the delivery of a liquid anesthetic agent to a sump of an anesthetic vaporizer, the system comprising: a filler assembly rotatable about a pivot point, the filler assembly comprising a sump valve, the sump valve controlling fluid communication between the filler assembly and the sump as the filler assembly is rotated about the pivot point; a filler spout connected in fluid communication with the filler assembly; a bottle cap configured for connection to an anesthetic bottle containing liquid anesthetic agent, the bottle cap having a bottle end and an end opposite the bottle end; an adapter having a bottle end and a vaporizer end, the bottle end being coaxial to the bottle cap and having a sealing surface that engages the bottle cap to form a seal against fluid communication between the anesthetic bottle and the adapter, the vaporizer end of the adapter extending away from the bottle cap, the vaporizer end of the adapter coupling with the filler spout; and a rail coupled to the anesthetic vaporizer, the rail having a cam surface, the cam surface varying in radial distance from the pivot point, the bottle cap contacting the rail such that rotation of the bottle cap and the adapter about the pivot point causes the cam surface of the rail to push the bottle cap radially along an axis from the pivot point, disengaging the sealing surface of the adapter from the bottle cap and opening the adapter to fluid communication with the anesthetic bottle.
