Abstract:
1. A universal medical gas delivery system ( 10 ) for coupling any of a plurality of different medical gas sources to a medical gas tube leading to any of a plurality of different medical gas utilizing devices comprising, in combination; a source of medical gas ( 20 ) comprising a cylindrical mate outlet ( 22 ) with an output orifice ( 24 ) and an inner bore ( 26 ) through which the source of medical gas is adapted to pass, and an outer cylindrical surface having threads ( 28 ); a flexible cylindrical elastomeric medical gas tubing ( 30 ) of an extended length having an inner diameter ( 32 ) and outer diameter ( 34 ), a input end ( 36 ) and a remote output end ( 38 ), the input end further comprising a tubing bushing ( 40 ) that makes a flush abutment with the cylindrical male outlet ( 22 ) of the source of medical gas ( 20 ) at the output orifice ( 24 ), and the remote output end ( 38 ) adapted to attach to any of a plurality of medical gas utilizing devices ( 42 ), and an annular flange ( 44 ) of the input end tubing bushing ( 40 ), the annular flange of the input end tubing bushing being adapted to reside within a central cylindrical bore ( 60 ) of a rotatable connector ( 50 ), thereby preventing the flexible cylindrical elastomeric medical gas tubing ( 30 ) and input end tubing bushing ( 40 ) from being separated from the rotatable connector; the rotatable connector ( 50 ) having a first opening ( 52 ) at a first end ( 54 ), a second opening ( 56 ) at a second end ( 58 ), the central cylindrical bore ( 60 ) extending through the first end ( 54 ) and to the second end ( 58 ) forming an interior surface ( 62 ), the interior surface of the rotatable connector having threads ( 64 ) and being adapted to couple with threads ( 28 ) of the cylindrical male outlet ( 22 ) of the source of medical gas ( 20 ), the second opening ( 56 ) of the rotatable connector ( 50 ) having a diameter ( 66 ) less than a diameter ( 68 ) of the annular flange ( 44 ) of the input end ( 36 ) tubing bushing ( 40 ) so that the second end ( 58 ) of the rotatable connector ( 50 ) serves as an annular abutment ( 48 ) against the annular flange ( 44 ), thereby holding the input end tubing bushing ( 40 ) against the cylindrical male outlet ( 22 ) of the source of medical gas ( 20 ) when the rotatable connector ( 50 ) is screwed on, and also to provide an airtight coupling; and at least one user gripping means ( 70 ) on an exterior surface of the rotatable connector ( 50 ) to assist a user in the coupling/screwing of the rotatable connector ( 50 ) to the cylindrical male outlet ( 22 ) of the source of medical gas ( 20 ), the gripping means ( 70 ) is chosen from physical gripping means including, but not limited to, grooves, fingertip indentations, radially protruding flanges, angled surfaces and edges, curved surfaces and edges, surface bumps and friction-causing rough surfaces.
