Abrégé

A combined one way inspiratory valve and expiratory release valve assembly is provided for controlling air flow in a respiratory treatment system. The valve assembly comprises a housing comprising a valve inlet, a valve outlet and at least one vent opening, and a diaphragm sealingly connected to the housing at an outer circumference of the diaphragm, wherein the diaphragm divides the housing into; a) an upstream portion, which is in fluid communication with the valve inlet, and b) a downstream portion which is in fluid communication with the valve outlet. The diaphragm has a circular, oval, elliptical or stadium shape. An inner portion of the diaphragm defines a one way inspiratory valve. An outer portion of the diaphragm defines an expiratory release valve. A method of characterising vent flow in a respiratory treatment system which includes such a valve is also described.

A patient interface includes a plenum chamber pressurisable to a therapeutic pressure, and a seal-forming structure constructed and arranged to seal with a region of a patient's face surrounding an entrance to a patient's airways. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in the plenum chamber throughout a patient's respiratory cycle in use. The patient interface also includes a positioning and stabilizing structure configured to hold the seal-forming structure in a therapeutically effective position on a patient's head. The positioning and stabilizing structure includes a rear strap arranged to contact an occiput of the patient's head. The rear strap is constructed from a first material is arranged to contact a temporal region of the patient's head, and a second material arranged to contact the occiput of the patient's head. The second material is silicone.
