A patient interface kit to deliver a flow of air at a positive pressure with respect to ambient air pressure to an entrance to a patients airways including at least the entrance of a patients nares while the patient is sleeping. The patient interface comprising: a nasal cushion having a nasal cushion opening; a mouth cushion having a mouth cushion opening, the mouth cushion including a flexible joint, positioned above the mouth opening, to selectively connect the nasal cushion to the mouth cushion; and a positioning and stabilizing structure to provide a force to hold the nasal and/or mouth seal-forming structures in a therapeutically effective position on a patient's head, the positioning an stabilizing structure including a nasal headgear including upper straps or conduits and a mouth headgear including lower straps, the mouth headgear being selectively connected to the nasal headgear.

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 flexible positive airway pressure (PAP) mask body, frame, and cushion are described. The mask body includes prongs that insert through and act upon apertures of the mask frame to connect the mask frame to the mask body. An airtight seal may be created between the mask body and the mask frame by a ball and socket connector, of the mask frame, having an elongated portion that extends through and has an outer perimeter commensurate with an aperture located in the mask body. The mask body may be configured with elongated portions that extend from the mask body chamber and to ends of eye sockets of the user. Headgear may couple to end portions of the mask frame corresponding to the elongated portions of the mask body. When pulling pressure by the headgear, additional contact is created between elongated portions of the mask cushion and the user's face.

Devices, systems, and methods for detecting a sealing condition between a patient interface and a patient, and adjusting the patient interface to maintain the patient interface in sealing contact with the patient. The patient interface may include a sealing structure to form a seal on the patient, and a positioning structure to secure the sealing structure to the patient. The patient interface may include a sensor coupled to the sealing structure. A processor determines the sealing condition between the sealing structure and the patient based on a signal from the sensor, and adjusts at least one of the sealing structure and the positioning structure to maintain the sealing structure in sealing contact with the patient. A prediction system predicts a leak between the sealing structure and the patient based on the sensor signal. A learning system learns how to fit the sealing structure to the patient to form a seal.

A patient interface with a sealing device, the sealing device comprising a support membrane and a sealing membrane. The sealing membrane is designed at least in part to bear on the skin of a patient and the support membrane extends at least in part adjacent to the sealing membrane. The distance between the support membrane and the sealing membrane is at least in part such that an interspace is formed.

A patient interface device includes a frame member and a cushion having a main body, a sealing portion, and first and second posts extending from the main body. The frame member defines a first orifice and a second orifice. The first post of the cushion is rotatably received within the first orifice and the second post is rotatably received within the second orifice in a manner that permits the cushion to rotate relative to the frame member.

A respiratory assembly is provided. The assembly includes a base engaged with at least one connector and in fluid communication with a hose or fluid source for allowing the gaseous flowthrough between the at least one connector, the base and the hose or fluid source. The assembly further includes a pair of sockets engaged with the at least one connector, and a pair of posts, each post selectively engageable with at least one of the pair of sockets. Each post includes a flange that defines an opening therethrough, the openings in fluid communication with each corresponding socket of the pair of sockets. Each post further includes an adhesive adhered to each flange and configured for sealably engaging a patient's nare.

A patient interface for respiratory therapy includes a nasal interface having nasal prongs configured to contact nares of the user and form a seal. The patient interface also includes a securement portion having a pair of facial pads, each of the facial pads configured to engage the face of a user on opposing sides of the nasal interface. The facial pads are coupled to the bridging portions configured to urge the nasal interface toward the user's face to create or maintain sealing engagement between the nasal interface and the user's face. In some configurations, the securement portion and the nasal interface are detachably coupled to each other.

The present invention includes a mask body having a cord attached at three locations on the mask body and a deformable bridge piece. The cord is attached at the middle of an upper edge of the mask body generally aligning with the location of the bridge of the wearer's nose. The cord is further attached at each of two lower positions on the mask body, preferably near or at the bottom corners of the mask body. The cord is further threaded through eyelets located at each of two upper positions on the mask body, preferably near or at the upper corners of the mask body. The deformable bridge piece is located along the upper edge of the mask body, and generally centered on the bridge of the wearer's nose.

To provide a mask capable of reducing a load of a patient while suppressing lowering of accuracy at which a subject's exhaled air is measured. A mask to be put on a subject's face includes a mask body portion demarcating an internal space in a state of covering part of the subject's face and a cup-shaped nasal cup covering a subject's nose in a state of being arranged inside the internal space, in which the nasal cup includes a first wall portion covering the subject's nose, a second wall portion arranged under the subject's nostrils, and an exhaled air discharge portion guiding an exhaled air from the subject's nose to an exhaled air sensor, and at least part of the exhaled air from the subject's nose is guided toward the exhaled air discharge portion by the second guide portion in a state where the nasal cup covers the subject's nose.
