Abstract:
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.
