More Information
Summary:A patient interface for sealed delivery of a flow of air to an entrance of a patient's airways, including at least the nares (3101) of the patient comprising: a plenum chamber (3200); and a seal forming structure (3100) comprising: a foam undercushion (3114) structured to releasably engage with the plenum chamber; and an air-impermeable textile membrane (3109) configured to contact the face of the patient during use, the air-impermeable textile membrane having an outer periphery that is joined to the foam undercushion by an airtight bond and an inner portion that lies freely on the foam undercushion such that the inner portion of the air-impermeable textile membrane is separable from the foam undercushion by the flow of air in use. The invention provides a seal forming structure that is comfortable for the user with less leakage of supplied air.
