Universal medical gas delivery system

摘要

A first source of medical gas has a generally cylindrical male outlet with a cylindrical bore and a threaded outer cylindrical surface. A flexible cylindrical elastomeric medical gas tubing has an input end with a bushing making a flush abutment with the male outlet at the output orifice. An output end attaches to any of a plurality of medical gas utilizing devices, but preferably with a dampening disperser held in position in the space in the vicinity of a patient's nose and mouth. An annular flange of the input end bushing resides within a central cylindrical bored out region extending through the first end and nearly to the second end of a rotatable connector forming an interior surface of a connector with threads coupling with the threads of the male outlet. The second end is an annular abutment against the annular flange holding the input end tubing bushing against the outlet source and providing an airtight coupling. A gripping means is on the exterior surface of the connector.

主权项

1. A medical gas delivery system that includes at least one dampening disperser (220), configured to be supported in a position in front of a patient's face, said dampening disperser (220) including at least some concave walls (226) of an at least a partial face mask housing (244), at least one gas outlet nozzle (234) that releases medical gas, and at least one non-stationary baffle (236) in a path of gas flow (230) to disperse and create drag, thereby reducing a velocity of the gas flow (230) coming from at least one medical gas supply tubing (30) attached to an at least one medical gas source outlet (22 or 82), while generating a turbulent plume of gases that mix with air in a space (228) in a vicinity of a patient's nose and mouth, chosen from vicinities including, but not limited to, between an upper lip and a base of the patient's nose, to allow for both nose breathing and mouth breathing of said turbulent plume of gases and to aid in clearance of exhaled breath away from the patient so as to diminish rebreathing of exhaled air, movement of said non-stationary baffle (236) is visualized to indicate that the patient is receiving gas flow, said at least one non-stationary baffle (236) is chosen from a class of baffles selected from a type of non-stationary baffles including, but not limited to, flexible flaps, sails, parachutes, wings and blades and rotating blades (238), including rotating blades of a fan, impeller, and windmill.
