NASAL ASSEMBLY
First Claim
1. 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 silicone 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;
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 adapted to pass around the rear portion of the user'"'"'s head, a top strap adapted 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,wherein each of the depending side straps includes a hook and loop fastener, andwherein the top strap is a coronal strap arranged and configured to engage the user'"'"'s corona and the back strap is an occipital strap configured and dimensioned to engage the user'"'"'s occiput.

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.
