摘要： A seal-forming structure for a patient interface may include a patient-contacting surface configured to engage the patient's facial skin to form a seal; a posterior opening formed in the patient-contacting surface, the posterior opening configured to provide the flow of air at said therapeutic pressure to the patient's nares; and a support structure extending from the patient contacting surface to an interior surface of the seal-forming structure, the support structure and the interior surface forming a continuous loop, wherein the patient interface is configured to allow the patient to breath from ambient through their mouth in the absence of a flow of pressurised air through the plenum chamber inlet port, or the patient interface is configured to leave the patient's mouth uncovered.

摘要： A mask apparatus for a respiratory treatment can permit delivery of breathable gas to a user. In one example, the mask may employ a frame and cushion to form a seal for both mouth and nose. The frame may be adapted for coupling with a respiratory treatment apparatus so as to permit communication of a pressurized gas from the respiratory treatment apparatus. The cushion, which may be foam, may have a substantially under the nose configuration or over the nose configuration. The mask may have a common plenum chamber for both nose and mouth. The cushion may further define a centrally open lip superior region. The cushion may be adapted to couple with the frame directly or to the frame in conjunction with a cushion support clip. Various features of the cushion may further promote sealing and comfort for the under the nose design.

摘要： 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.

摘要： A cushion assembly for a patient interface includes an elastomeric seal-forming portion with a dome-shaped superior region that is intersected by the sagittal plane in the vicinity of a superior tangent point. The seal-forming portion further including a saddle-shaped inferior region that is intersected by the sagittal plane and includes an inferior tangent point. A first support region is located on one side of the sagittal plane between the inferior region and the superior region, the exterior surface of the elastomeric seal forming portion at the first support region being cylinder-shaped and/or saddle-shaped. In addition, a blowout prevention system is configured to counter a force acting on the unsupported edge of the elastomeric seal-forming portion due to a pressure within the chamber, the blowout prevention system being attached to the elastomeric seal-forming portion at the first support region of the elastomeric seal-forming portion.

摘要： A patient interface comprises a seal-forming structure including a textile membrane and a support structure to support the textile membrane. The seal-forming structure may have a varying construction in order to accommodate different regions and the varying contours of the patients face to ensure a robust and comfortable seal. An air impermeable layer of the textile membrane may have a thickness that varies in different portions of the textile membrane and/or different regions of the cushion assembly. Further, the seal-forming structure may include an underlying cushion, and an arrangement of the textile membrane and the underlying cushion and/or the configuration of the underlying cushion may vary in different regions of the cushion assembly to optimize patient comfort and the effectiveness of the seal in different regions of the patients face.

摘要： 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.

摘要： A patient interface may include a plenum chamber pressurisable to a therapeutic pressure, a seal-forming structure constructed and arranged to form a seal with a region of the patient's face surrounding an entrance to the patient's airways, a positioning and stabilising structure to provide a force to hold the seal-forming structure in a therapeutically effective position on the patient's head, and a vent structure to allow a continuous flow of gases exhaled by the patient from an interior of the plenum chamber to ambient, wherein the patient interface is configured to leave the patient's mouth uncovered during therapy, wherein the seal-forming structure comprises two lateral support regions, each located at a lateralmost side of the seal-forming structure, and a medial region positioned between the lateral support regions, the hole passing through the medial region, and wherein the lateral support regions are thicker than the medial region.
