A sealing apparatus for use in combination with an oropharyngeal device for maintaining a patient airway, the oropharyngeal device having a hollow airway tube with proximal end and a distal end, the proximal end being adapted to be fluidly coupled with a supply of gas for passage of air or medical gas wherein the device is adapted for insertion through the mouth of a patient and with one end into the pharynx of a patient above and spaced from the epiglottis of the patient, the sealing apparatus comprising: a flexible sheet adapted to be placed over a user's face; and the flexible sheet comprising an opening to allow the distal end of the tube to be passed therethrough, the opening being dimensioned to prevent the proximal end of the tube from being passed through the opening.

A patient interface includes a seal-forming structure, a shell, and an AAV. The shell and the seal-forming structure form at least a portion of a plenum chamber pressurizable to a therapeutic pressure. The shell includes a first port into the plenum chamber, the first port configured to allow air to flow between the plenum chamber and ambient. The shell includes a passageway including a second port into the plenum chamber, the passageway configured to communicate with a flow of air at positive pressure. The AAV is provided to the shell and configured to regulate flow through the first port and the second port to (1) provide a flow path for pressurized air when pressure in the plenum chamber is above a predetermined magnitude and (2) provide a breathable flow path when pressure in the plenum chamber is below the predetermined magnitude or not delivered.

The present technology relates to one or more of the screening, diagnosis, monitoring, treatment, prevention and amelioration of respiratory-related disorders. The present technology also relates to medical devices or apparatus, and their use. In particular, the present technology a headgear for supplying pressurised air to a patient, comprising a headgear tubing which is inflatable from a collapsed state to an inflated state to form a conduit for supplying pressurised air to the patient, and when the headgear tubing is in the collapsed state, the headgear tubing is elastically deformable and foldable on itself. The headgear may further comprise a rigidiser.

An apparatus including a patient interface device formed from a flat substrate that is folded, wherein the patient interface device includes a plurality of seams where sections of the substrate are joined together, and wherein one or more of the plurality of seams form a shape that corresponds to a perimeter of a bottom side of a nose from a first alare corner of the nose to a tip of the nose to a second alare corner of the nose.

A respiratory mask includes a mask body having a face-engaging portion, and at least one retaining member connected to the mask body and including at least one engaging member for receiving and tethering a liner to the respiratory mask to generally overlie the face-engaging portion. The retaining member may include a flexible elongated body having a central portion and opposing ends, and a bottom surface arranged to be attached to the respiratory mask. The liner may include a liner body constructed from an absorbent material and having an outer edge, an inner edge, and an opening bounded by the inner edge, wherein an extending portion of the liner body is defined which extends outwardly beyond the face-engaging portion and includes at least one aperture for engaging the retaining member. A kit for use with a respiratory mask includes at least one liner and at least one retaining member.

A patient interface including a seal-forming structure with a textile 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 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.

A facemask configured to be used by multiple sized/shaped heads can include a primary, a secondary and a tertiary seal. In some embodiments, the primary seal is contact with the nose and cheek regions; the secondary seal is in contact with the chin region; and the tertiary seal is in contact with the cheek and chin regions. In some embodiments, the tertiary seal extends inwardly and outwardly when applied to the face. In some embodiments, the mask includes test scissors.

A wearable device (8,60,70,86) structured to exert a contact pressure between the wearable device and a skin surface of a wearer, such as a patient interface device for delivering a flow of breathing gas to a patient, includes a first member (18,72,96), such as a faceplate member, structured to have a first pressure applied thereto, a contact member (14,74), such as a sealing cushion, structured to exert the contact pressure against the skin surface in response to the first pressure, and a support member (20,62,78) positioned between the first member and the contact member, the support member including a plurality of compression members (40,52,54,64,84), wherein each of the compression members is structured to buckle in response to a compression force having at least a first predetermined level being applied to the support member.

An oxygen face mask composed of a molded vinyl/polyvinyl/rubber or silicone mask with a medical grade mineral oil gel strip on the bridge of the nose extending over the contour of the cheeks on both side of the patient's face, an extended under-the-chin portion of mask and decreased length dimension of an existing standard face mask to deliver oxygen and aerosolized medications to the user. Use of this face mask during aerosolized medication of medical gas or oxygen delivery allows for a better seal against the face, greater comfort to the user, more stability and good securement of the mask, and a mask size that decreases irritation of the user's eyes caused by leakage at the nose and cheek portions of a standard oxygen mask. The oxygen mask configuration can applied to both pediatric and adult patients.

A mask system including a frame module and a cushion module provided to the frame module and adapted to form a seal with the patient's face. The cushion module includes a main body defining a breathing chamber and adapted to interface with the frame module and a cushion adapted to form a seal with the patient's face. The main body and the cushion are comolded with one another.
