Cushion for patient interface

A cushion assembly for a patient interface includes an elastomeric seal-forming portion that includes a dome-shaped superior region and a saddle-shaped inferior region. The elastomeric sealing portion further includes a first support region extending from the saddle-shaped inferior region to the dome-shaped superior region, the first support region having a consistent elastomeric wall thickness that is greater than the elastomeric wall thickness of the dome-shaped superior region and the saddle-shaped inferior region. In addition, the seal-forming portion include a second support region adjacent the first support region that extends from the saddle-shaped inferior region to the dome-shaped superior region, the second support region being bounded by the first support region on a proximal side and having a distal side opposite the proximal side, the elastomeric wall thickness in the second support region increases from the distal side to the proximal side.

Patient interface with a seal-forming structure having varying thickness

A patient interface for delivering breathable gas to a patient includes a nasal prong assembly including a pair of nasal prongs structured to sealingly communicate with nasal passages of a patient's nose in use and headgear to maintain the nasal prong assembly in a desired position on the patient's face. The headgear includes side straps and rigidizers provided to respective side straps. Each rigidizer includes a first end portion that provides a connector structured to engage a respective end of the nasal prong assembly and an inwardly curved protrusion in the form of a cheek support that curves inwardly of the connector. The cheek support is adapted to follow the contour of the patient's cheek and guide a respective end portion of the side strap into engagement with the patient's cheek to provide a stable cheek support.

Patient interface

A nasal patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways includes a cushion member that includes a retaining structure and a seal-forming structure permanently connected to the retaining structure, a frame member attachable to the retaining structure, and a positioning and stabilising structure releasably attachable to the frame member.

Patient interface and method for making same

A mask system includes a cushion for a mask that seals at its upper extent in a region of the nose that is generally above the tip of the nose or pronasale, and extends across a portion of the cartilaginous framework, alar or flares of the patient's nose, e.g., not extending over or across the nasal bone of the patient's nose.

Nasal mask system

A patient interface may include: a plenum chamber at least partly defining a patient interface chamber, a seal-forming structure constructed and arranged to form a seal with a region of the patient's face, at least one conduit, at least one conduit connector configured to pneumatically connect the at least one conduit to the plenum chamber to provide a flow of air at a therapeutic pressure to the patient interface chamber for breathing by the patient, and a positioning and stabilising structure to provide a force to hold the seal-forming structure on the patient's head, the positioning and stabilising structure comprising at least one tie, wherein the at least one conduit connector includes an anti-asphyxia valve configured to allow the patient to breath from ambient through their mouth in the absence of a flow of pressurised air.

Conduit headgear connector for patient interface

A cushion assembly for a patient interface including an elastomeric seal-forming structure that is shaped to be bisected by a sagittal plane having a line that is tangent to the elastomeric seal-forming structure at a superior tangent point and at an inferior tangent point. A saddle-shaped superior region of the elastomeric seal-forming structure straddles the sagittal plane and includes the superior tangent point. The elastomeric seal-forming structure transitions in a cylinder-shaped superior region from the saddle-shaped region to a dome-shaped superior region offset from the sagittal plane. In addition, an elastomeric wall thickness of the elastomeric seal-forming structure is greater in the cylinder-shaped superior region than in the saddle-shaped superior region and the dome-shaped superior region.

A cushion assembly for a patient interface for sealed delivery of a flow of air at a continuously positive pressure to a patient's airways includes a foam cushion configured to sealingly engage the patient's face; and an elastomeric support portion configured to support the foam cushion and form at least part of a plenum chamber with the foam cushion. The elastomeric support portion includes a support structure and a folded section extending radially inward from the support structure. The folded section acts as a seat for the foam cushion, and the folded portion is configured to allow the foam cushion to roll inward toward an interior of the chamber in response to a compressive force acting on the foam cushion.

Patient interface with foam seal-forming structure

A shroud for a mask system includes a retaining portion structured to retain a frame, a pair of upper headgear connectors each including an elongated arm and a slot at the free end of the arm adapted to receive a headgear strap, and a pair of lower headgear connectors each adapted to attach to a headgear strap. The retaining portion, the upper headgear connectors, and the lower headgear connectors are integrally formed as a one piece structure.

Mask system with shroud and vent holes

Headgear clip for patient interface

Pair of stabilizer arms for patient interface

A patient interface including a seal-forming structure with an elastomeric membrane that has at least one hole such that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patients nares and/or an entrance to the patients mouth. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patients respiratory cycle, in use. The elastomeric membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The elastomeric membrane is molded to include a three-dimensional shape that has multiple curvatures. The at least one hole includes an arch on a lateral side of the at least one hole, and is in a relaxed state before use. The arch is configured to move to a substantially taut state during use.

Textile seal-forming structure with multiple curvatures

A patient interface system for delivering breathable gas to a patient includes a patient interface configured to sealingly engage the patient's face. A mechanism may be provided to ensure that an effective seal is maintained between the patient interface and the patient's face by preventing, reducing, minimizing or limiting effects of disruptive forces, such as tube drag, on the patient interface.

Patient interface systems for ensuring effective seal

A patient interface including a seal-forming structure with a textile membrane. The textile membrane has at least one hole such that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patient's nares. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patient's respiratory cycle, in use. The textile membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The taut state of the second portion is configured to allow the seal-forming structure to include a three-dimensional shape that has multiple curvatures.
