Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
189 words
An improved nasal adapter for administering gas analgesia which comprises a nosepiece for covering the nose and means for connecting the nosepiece with a source of gaseous analgesia, said nosepiece being provided with respiratory check valves for associated air intake and expiration with each respective check valve being in turn provided with adjustable regulatory controls for air intake and expiration and sealing means being provided for said nosepiece, so that when said adapter is placed over the nose there will be allowed into said adapter the introduction of a mixture of gaseous analgesia and air and the expiration of the residue of said mixture from said adapter, in controlled amounts and wherein said nosepiece has opposing lateral sides, an underside, a closed side and an open side, the air intake respiratory check valve being located in one of said lateral sides, said source of gaseous analgesia being introduced through the other said lateral side, and the expiration respiratory check valve being located in said underside and includes means for directing the expiration of the residue of gaseous analgesia and air downwardly and towards the open side of said nosepiece.
