Abstract
A nasal assembly for delivering breathable gas to a patient includes a frame having an integrally formed first connector portion. A nozzle assembly includes a gusset or base portion and a pair of nozzles. At least one inlet conduit is structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient. A pair of second connector portions are removably and rotatably connected to respective first connector portions of the frame and are in communication with respective inlet conduits, e.g., directly or via angle connectors. A headgear assembly is removably connected to the pair of second connector portions and/or the angle connectors so as to maintain the frame and the nozzle assembly in a desired adjusted position on the patient'"'"'s face.

53. A nasal interface for delivering pressurized breathable gas to a user, comprising:
-
a support frame having a central portion and a pair of lateral support arms extending laterally away from the central portion, each lateral support arm including an integrally formed connector slot;
a pillows cushion including a base portion and a pair of nozzles, the pillows cushion being removably coupled with the central portion of the support frame with the pair of nozzles structured to sealingly engage with nasal passages of a user'"'"'s nose in use, wherein the nozzles, as a unit, are rotatably adjustable between a plurality of frictionally locked positions to align the nozzles with the nasal passages of the user;
an inlet tube having a first end provided with a swivel connector to be connected to a source of pressurized breathable gas via an air delivery tube, and a second end provided to deliver the gas into the support frame for breathing by the user via the pillows cushion; and
headgear including a back strap to pass around the rear portion of the user'"'"'s head, a top strap to pass over the top of the user'"'"'s head, and a pair of depending side straps each of which is suspended from a junction between the back and top straps, said depending side straps being configured to extend forwardly of the ear along the user'"'"'s face, each of said depending side straps having an end received in a respective one of said connector slots of said lateral support arms. - View Dependent Claims (54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 115, 138, 139, 140, 141, 142, 143, 144)

108. A nasal assembly for delivering pressurized breathable gas to a user, comprising:
-
a substantially rigid support frame having a central portion and a pair of lateral support arms extending laterally away from the central portion, each lateral support arm including an integrally formed connector slot, wherein the lateral support arms are formed in one piece with the central portion;
a one piece silicone nozzle assembly including a base portion and a pair of nozzles, the nozzle assembly being removably coupled with the central portion of the support frame with the pair of nozzles structured to sealingly engage with the nasal passages of a user'"'"'s nose in use, wherein the nozzles as a unit are locally rotatably adjustable in close proximity to the user'"'"'s nose in use, to align the nozzles with respect to the nasal passages of the user;
an inlet tube provided to deliver pressurized breathable gas into the support frame for breathing by the user via the nozzle assembly;
headgear including a back strap to pass around the rear portion of the user'"'"'s head, a top strap to pass over the top of the user'"'"'s head, and a pair of depending side straps each of which extends from a junction between the back and top straps, each of said depending side straps having an end received in a respective one of said connector slots of said lateral support arms; and
an exhalation port provided to the central portion and including a series of orifices for CO2 washout. - View Dependent Claims (109, 110, 111, 112, 113, 114, 116, 117, 118, 119, 120, 121, 122, 123, 124, 125, 126, 127, 128, 129, 130, 131, 132, 133, 134, 135, 136, 137, 145, 146, 147, 148, 149, 150, 151, 152, 153, 154)

155. A nasal interface for delivering pressurized breathable gas to a user, comprising:
-
a rigid support frame;
a one piece silicone nozzle structure including a common base portion and a pair of nozzles extending from the base portion, the nozzle structure being removably coupled with the support frame with the pair of nozzles structured to sealingly engage with nasal passages of a user'"'"'s nose in use; and
an adjustment mechanism in close proximity to the nose to allow localized, rotatable and unified adjustment of the nozzle structure, to align the nozzles with respect to the user'"'"'s nasal passages;
a headgear to support the support frame and nozzle structure on the user'"'"'s face, wherein the headgear includes a back strap to pass around the rear portion of the user'"'"'s head, a top strap to pass over the top of the user'"'"'s head, and a pair of depending side straps each of which is suspended from a junction between the back and top straps, said depending side straps being configured to extend forwardly of the ear along the user'"'"'s face, wherein;
each junction between the top, back and depending side straps has a general Y-shape, the back strap extends from the junction and forms an angle that is slightly below horizontal in use, the top strap extends from the junction and forms an angle that is slightly forward of vertical in use, the angle between the top and back straps is obtuse, and each of the depending side straps includes hook and loop fastener. - View Dependent Claims (156, 157, 158, 159, 160, 161, 162, 163, 164)
