Abstract

patient interface for sealed delivery of a flow of air at a continuously positive pressure with respect to ambient air pressure to an entrance to a patient’s airways, comprising a seal forming structure (3100) formed from an air impermeable textile material. The seal forming structure comprises a flexible membrane and an opening (3101) to direct the flow of air to the patient's airways. The interface is characterised by having a mesh structure (3102) integrated with the seal forming structure at the opening. The invention provides a patient interface with a mesh structure that can act as a filter for particulate matter or a heat and moisture exchanging (HME) material that absorbs heat and moisture from gas exhaled by the patient, which is then transferred to the flow of pressurized gas as it travels to the patient's airways during inhalation.

Claims (14)

1. A patient interface for sealed delivery of a flow of air at a continuously positive pressure with respect to ambient air pressure to an entrance to the patient’s s including at least a patient’s nares, wherein the patient interface is configured to maintain a therapy re in a range of about 4 cmH2O to about 30 cmH2O above ambient air pressure in use, throughout the patient’s respiratory cycle, while the t is sleeping, to ameliorate sleep disordered breathing, the patient interface comprising: a plenum chamber configured to be rised at a pressure above ambient pressure by the flow of air, the plenum chamber having a connection port configured to be connected to an air delivery tube to receive the flow of air; a seal-forming structure formed from a first textile material that is air impermeable, the seal g structure comprising: a membrane configured to contact the patient’s face and seal around the entrance to the patient’s airways including at least the patient’s nares, the seal-forming structure having an opening configured to direct the flow of air to the entrance to the patient’s airways including at least the patient’s nares; and a mesh structure ated with the orming structure at the opening; a vent comprising a plurality of vent holes configured to wash out exhaled gas from the patient during use; and a positioning and stabilising structure configured to maintain the seal-forming structure in g contact with the patient’s face, the positioning and stabilising structure sing at least one strap constructed from a second textile material, JAWS ref: 506108NZDIV2 ResMed Ref: P1135NZ3 wherein the seal-forming structure is configured to inflate under internal pressure when the membrane is sealed against the patient’s face, and wherein the membrane is flexible.
2. The patient interface of claim 1, wherein the mesh structure comprises a ing material ured to filter undesirable particulate matter from the flow of air before reaching the patient’s airways.
3. The t interface of claim 1, wherein the mesh structure comprises a heat and moisture exchanging (HME) material configured to absorb heat and re from gas d by the patient and release heat and moisture into the flow of air as it travels to the t’s airways during tion.
4. The patient interface of claim 1, wherein the mesh structure comprises foam.
5. The patient interface of any one of claims 1 to 4, wherein the first textile material is laminated with an air-impermeable material on a side that does not contact the patient.
6. The patient interface of any one of claims 1 to 5, wherein the second e material is air-permeable.
7. The patient interface of any one of claims 1 to 6, wherein the oning and stabilising structure further comprises a pair of side straps, each of the side straps configured to pass along a corresponding side of the patient’s face.
8. The patient interface of claim 7, wherein the positioning and stabilising structure further comprises a pair of rigidiser arms configured to pass along a corresponding side of the patient’s face, each of the rigidiser arms being connected to the plenum chamber by a rigidiser arm connector, and each of the rigidiser arms being concealed by a corresponding one of the side straps. JAWS ref: 506108NZDIV2 ResMed Ref: P1135NZ3
9. The patient interface of claim 8, wherein each of the side straps is configured to cushion the patient’s face t a corresponding one of the rigidiser arms.
10. The patient interface of claim 7, wherein the positioning and stabilising structure further comprises a crown strap ured to pass over the top of the patient’s head and a rear strap configured to pass behind the patient’s head.
11. The patient interface of claim 10, wherein the crown strap and the rear strap are connected to each of the side straps.
12. The patient interface of any one of claims 1 to 11, wherein the vent is positioned on the plenum chamber.
13. The patient ace of any one of claims 1 to 12, wherein the sealforming structure is a nasal cradle configured to seal around an inferior periphery of the patient’s nose and at or near the tip of the patient’s nose.
14. The patient interface of any one of claims 1 to 13, n the seal- g structure is configured to leave the patient’s mouth uncovered.
