ABSTRACT:
A patient interface assembly adapted to be connected to a gas supply pump to deliver breathable gas to the inlet of a patient's respiratory system comprises a supply conduit, a patient interface, a branch swivel connector including a Y-piece and an elbow that swivels relative to the Y-piece, the branch swivel connector being adapted to be located to the rear of a patient's head in use and being connected to the supply conduit. A pair of inlet tubes each have a first end positioned in use near a mouth of a patient and are connected to the nose mask, a middle portion arranged to pass across a cheek of a patient and an end portion being joined to the Y-piece of the branch connector. The inlet tubes have a flat configuration and are provided with a plurality of internal ribs which prevent the tubes being crushed. A strap is secured to the patient interface and adapted to pass around the sides and rear of the head to hold the patient interface in position on the head.
