Abstract

A patient interface can have features improving the comfort of use by reducing the perceived pressure of a nose-contacting cushion of the patient interface against the nose. The patient interface can have rigid headgear connection elements connectable to a frame of the respiratory interface. The rigid headgear connection elements can be shaped to reduce the force of the cushion against the nose. Headgear for a patient interface can also have features improving the stability of headgear of the head. The headgear can have a relatively rigid framework and a relatively pliable overlay covering the framework. The framework can have apertures defining a front portion to be positioned below or near the cheekbones, a rear portion to be positioned over the sides of the head around the ears, and a top portion to extend upward along the head towards the crown.

Claims31

Dependent claims

A headgear connection element for a patient interface for use with respiratory therapy, the headgear connection element comprising:

a first end adapted to interface with a headgear;
a second end adapted to interface with a frame of the patient interface;
and
a body extending between the first end and the second end substantially along a first axis;
wherein the second end comprises a body portion connected to the body and a projection comprising a first portion extending from the body portion of the second end along a second axis substantially transverse to the first axis and a second portion laterally offset from the body portion of the second end, the second portion extending from the first portion in a direction substantially parallel to the first axis, the second portion is wider than the first portion, and the projection adapted to protrude through the frame of the patient interface such that the body portion is located on a first side surface of the frame and the second portion of the projection is located on a second side surface of the frame opposite the first side surface.
