- a substantially planar piece of material which includes at least one slit before use,
- wherein the at least one slit is expandable to form a substantially enlarged open area in use, so that the material substantially surrounds an occiput of a patient's head.
A method of making headgear, comprising:
- providing a single piece of material;
- creating a plurality slits in the material;
- orienting the slits such that placement of the headgear on a patient's head expands the plurality of slits to form a plurality of open areas spread over the patient's head in use,
- wherein the material includes at least first and second strap end portions adapted for connection to a mask assembly.
Headgear for use with a respiratory mask assembly, comprising:
- a substantially planar piece of material which includes at least one slit before use,
- wherein the at least one slit is expandable in use to define at least one open area bordered on all sides by at least a portion of the material.
A method of making headgear for use with a respiratory mask assembly, the method comprising:
- providing a single piece of material;
- creating at least one slit in the material;
- orienting the at least one slit such that placement of the headgear on a patient's head expands the at least one slit to form at least one open area bordered on all sides by at least a portion of the material,
- wherein the material includes at least first and second strap end portions adapted for connection to a mask assembly.
A mask assembly for a patient, comprising:
- a flexible frame comprising an opening in a rear surface configured to receive a nose of the patient, the opening having a perimeter, the frame further comprising an upstanding wall extending along the perimeter, a lateral perimeter flange extending around the perimeter and comprising a plurality of apertures;
