A vent arrangement is provided to a mask or associated conduit to discharge exhaled gas from the mask to atmosphere. The vent arrangement is structured to diffuse the exhaust vent flow to produce less air jetting, thereby increasing the comfort of the patient and their bed partner. For example, the vent arrangement may include one or more grill components and/or media constructed and arranged to diffuse vent flow.

Mask vent

A patient interface includes a sealing arrangement adapted to provide an effective seal with the patient's nose, an inlet conduit arrangement adapted to deliver breathable gas to the sealing arrangement, and a cover that substantially encloses the sealing arrangement and/or the inlet conduit arrangement.

Delivery of respiratory therapy

A mask system may deliver a supply of air generated by a flow generator at a positive pressure in a therapeutic range to a patient's airways to treat sleep disordered breathing. The mask system may include: a cushion, a mask frame attached to the cushion, the mask frame having a front surface opposite the cushion and a bore projecting from the front surface to form a hole, and the mask frame having a curved interfacing structure projecting radially from the bore, and said mask frame having no built-in or integral headgear attachment points, headgear, an elbow assembly, and a headgear connector detachably connected to the mask frame by translating the mask frame and the headgear connector towards one another, wherein the mask frame and the headgear connector are constructed to resist movement between the mask frame and the headgear connector when said mask frame and said headgear connector are attached.

Mask system with removable headgear connector

An air delivery conduit for conveying breathable gas from a positive airway pressure device to a patient interface includes a tubular wall structure constructed from a textile material. A reinforcing structure may be provided to the wall structure that is structured to prevent kinking or collapsing of the wall structure. The wall structure may include a warp having a plurality of lengthwise textile warp threads arranged in a circle and a weft having a textile weft thread that is woven through the warp threads.

Air delivery conduit

A patient interface system for delivery of a supply of air at positive pressure to the entrance of a patient's airways for treatment of sleep disordered breathing includes an air delivery tube connected to a flexible portion of a plenum; a vent structure having sufficient rigidity to support its own weight under gravity and/or not to block or fold under tube movement or tube drag; and a patient interface structure. The patient interface structure includes a seal forming structure arranged on a top portion of the plenum; and a seal positioning and stabilizing structure connected to a flexible portion of the plenum. The seal-forming structure is substantially decoupled from a tube drag force.

Patient interface systems

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.

Respiratory apparatus

A patient interface for delivery of a supply of pressurised air or breathable gas to an entrance of a patient's airways comprising: 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 attachable to the frame member.

Patient interface

A mask for delivering breathable gas to a patient at positive pressure to treat sleep disordered breathing, may comprise: a rigid mask frame having a bore and an interfacing structure, the interfacing structure being located on the rigid mask frame and along a peripheral edge of the bore, said mask frame having no built-in or integral headgear attachment points; a sealing cushion provided to the rigid mask frame and adapted to form a seal with the patient's face, the rigid mask frame and the sealing cushion together forming, at least partly, a breathing cavity; and a headgear connector adapted to engage the interfacing structure with a snap-fit, said headgear connector including a pair of lower headgear clip anchors adapted to be engaged with respective ones of a pair of lower headgear clips to attach a pair of lower side straps, said headgear connector including a fixed forehead support.

Mask with headgear and rigidizers

A system of breathing arrangements for delivering breathable gas to a patient includes at least first and second cushion components, e.g., full-face, nasal, nasal prongs, nose tip, and/or a combination of any of the above, including a nasal or full-face cushion and nasal prongs/nozzles combination, etc., that are different from one another in at least one aspect, and a common frame assembly configured to support each of the first and second cushion components. Various embodiments are directed to a full-face or nasal mask used with a frame having lateral connector portions having a stiffening member. The mask assembly may include a nose height adjustment device for the height of the cushion, or a cushion adjustment member by which the position of the cushion may be adjusted relative to the frame. The mask assembly may include a chin strap assembly.

Interchangeable mask assembly

A patient interface is configured to deliver a pressurized flow of respiratory gas to a patient's airways. The patient interface includes a cushion and shell assembly with a cushion portion mounted on a shell portion that is more rigid than the cushion portion. The cushion portion is configured to sealingly engage the patient's face and has a vent opening. The shell portion includes a plurality of headgear connectors. The patient interface further includes a gas washout vent assembly configured to be positioned within the vent opening of the cushion portion. The gas washout vent assembly includes a main body configured to be secured to the cushion portion, a porous body, and an outer cover with a plurality of openings. The main body at least partially houses the porous body and the outer cover.

Method and apparatus for managing moisture buildup in pressurised breathing systems

A patient interface assembly is configured to deliver pressurized respiratory gas to a patient's airways. The patient interface assembly includes a cushion configured to sealingly engage the patient's face, a plenum base supporting the cushion, and a positioning and stabilizing structure configured to support the cushion and the plenum base on the patient's face. The positioning and stabilizing structure includes a stiffened portion. The patient interface assembly further includes a removable sleeve. The stiffened portion of the positioning and stabilizing structure is inserted into the removable sleeve. The removable sleeve is configured to be secured to the stiffened portion of the positioning and stabilizing structure by inserting a projection into a side cutout, and the stiffened portion of the positioning and stabilizing structure is prevented from sliding out of the removable sleeve when the projection is received within the side cutout.

An air delivery system for providing a supply of air from a source of air at positive pressure to an interfacing structure located at the entrance to the airways of a patient includes a manifold adapted to connect with the supply of positive air pressure and at least one tube connected to the manifold and adapted to deliver the supply of air to the interfacing structure. Each tube is structured to allow movement between an open phase in which the tube allows the passage of air and a collapsed phase in which the tube is collapsed. Each tube is structured such that weight of a typical patient's head against bedding apparel is sufficient to collapse the tube from the open phase to the collapsed phase.

Delivery of respiratory therapy using a detachable manifold

A patient interface assembly includes a flexible cushion configured to sealingly engage the patient's nares and a frame with a pair of flexible extending members that extend laterally from opposite sides of the frame. The frame and the flexible cushion together form a chamber. The patient interface assembly also includes a positioning and stabilising structure configured to maintain the flexible cushion in engagement with the patient's nares. The positioning and stabilizing structure has a pair of headgear straps. Each headgear strap is connected to a respective one of the flexible extending members. The flexible extending members do not form an airflow path for the breathable gas. The headgear straps have a multi-layered structure, at least one layer being made of fabric and at least one layer being made of plastic. In addition, the at least one plastic layer is a rigidizer that adds rigidity to the respective headgear strap.
