Breathing assistance apparatus

摘要

Headgear for use with a respiratory mask is described. The headgear comprises a continuous and substantially curved elongate member extending in use below a user's nose and at least two headgear straps capable of attachment to the ends of the elongate member. A mask attachment on the elongate member is disposed to sit below or on one of said user's nose, mouth, upper lip and an inlet to the mask. The attachment is capable of receiving the mask.

主权项

1. A patient interface system to treat a respiratory disorder of a patient by channeling airflow to the patient from a positive airway pressure device, the patient interface system comprising:
(a) a mask system having:
a mask body defining a rigid structure that supports a relatively softer cushion, the rigid structure comprising an inlet, the inlet extending through a laterally central portion of a forwardly facing surface of the mask body;the cushion being configured to contact a face of the patient in such a manner as to provide airflow to a mouth of the patient as well as to one or more nasal passages, the mask body and the cushion together defining a plenum;a support member supporting the mask body, the support member having a central portion and a pair of side arms, at least part of the central portion of the support member extending below the inlet of the mask body, the side arms having a first rigidity and each of the side arms having a length, the side arms extending laterally outward away from the mask body and having a bend along the length of each of the side arms such that at least a portion of each of the side arms is inclined vertically upward toward distal ends that are positioned away from the mask body;an elbow removably connected to the inlet of the mask body, the elbow being swivelable relative to the mask body; andan exhaust vent that comprises a plurality of vent holes to allow a continuous flow of air out the plenum defined by the mask body and the cushion; and (b) a headgear assembly comprising:
a pair of straps that are attached to at least the distal ends of the side arms, the pair of straps having a second rigidity that is different from the first rigidity of the side arms.
