A patient interface system for delivering a flow of breathable gas to a patient includes a patient interface structure configured to sealingly engage the patient's nares; a pair of strips configured to be connected to opposite sides of the patient interface structure; and adhesive configured to secure the patient interface structure in sealing engagement with the patient's nares. The adhesive may be provided on the strips, and the strips are configured to be adhered to sides of the patient's nose by the adhesive. Another patient interface system includes a first component including adhesive on a first side and hook or loop fastener material on a second side, wherein the adhesive is configured to adhere the component to the face of the patient; and a patient interface structure configured to sealingly engage the patient's airways. The patient interface structure includes a second component including a corresponding loop or hook fastener material configured to engage the corresponding hook or loop fastener material of the first strip to secure the patient interface structure in sealing engagement with the patient's face. A patient interface system for delivering a flow of breathable gas to a patient includes a patient interface structure including a pair of nasal prongs or pillows configured to sealingly engage the patient's nares; and at least one spring configured to bias the nasal prongs or pillows outwards into engagement with the nares of the patient.

An integrally molded ventilation interface includes a hollow bellows-like structure and two nasal prongs extending from a top surface of the bellows. A pair of headgear strap flanges can also be molded integrally with the ventilation interface. The nasal prongs provide a first sealing interface between an outer surface of the nasal prongs and an inner surface of the patient's nares. The bellows provides a second sealing interface between a top surface of the bellows-like structure and a bottom surface of a patient's nose. The headgear strap flanges provide a third sealing interface between the ventilation interface and a mustache region of the patient's face as well as a bottom surface of the patient's nose.

A combination mouth and nasal mask (40) for assisted respiration or CPAP is disclosed. The combination mask (40) has a frame (42) to the rear side of which is mounted a separate nasal cushion (44) and mouth cushion (46). Both the nasal cushion (44) and the mouth cushion (46) separately form a rolled edge seal around the patient's face in the vicinity of the nose and in the vicinity of the lips. Inlet air is communicated from within the housing (48) to the mouth chamber, circumscribed by the mouth cushion (46) by means of one or more interconnecting tubes (62). The proportion of air communicated to the mouth chamber (48) is controlled by the sizing and number of the tube(s), thus providing for free flow of air, restricted flow of air and pressure equalization, or zero flow of air. A mouth mask (10) for assisted respiration or CPAP also is disclosed.

A respiratory mask assembly for delivering breathable gas to a patient includes a frame and a headgear assembly which are adapted to being removeably magnetically coupled to one another at a desired angular orientation therebetween.

A PAP system for delivering breathable gas to a patient includes a flow generator to generate a supply of breathable gas to be delivered to the patient; a humidifier including a heating plate to vaporize water and deliver water vapor to humidify the supply of breathable gas; a heated tube configured to heat and deliver the humidified supply of breathable gas to the patient; a power supply configured to supply power to the heating plate and the heated tube; and a controller configured to control the power supply to prevent overheating of the heating plate and the heated tube.

A nasal assembly for delivering breathable gas to a patient includes a frame having an integrally formed first connector portion. A nozzle assembly includes a gusset or base portion and a pair of nozzles. At least one inlet conduit is structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient. A pair of second connector portions are removably and rotatably connected to respective first connector portions of the frame and are in communication with respective inlet conduits, e.g., directly or via angle connectors. A headgear assembly is removably connected to the pair of second connector portions and/or the angle connectors so as to maintain the frame and the nozzle assembly in a desired adjusted position on the patient's face.

A patient interface device that includes a frame sized and configured to span at least a portion of a patient's face while remaining below the patient's eyes when the patient interface device is donned by the patient. A support member is coupled to the frame such that the support member is moveable relative to the frame. A sealing assembly is attached to the support member. A pair of patient contacting members are operatively coupled to the frame and supporting the frame on a patient's face.

A nasal assembly for delivering breathable gas to a patient includes a frame having an integrally formed first connector portion. A nozzle assembly includes a gusset or base portion and a pair of nozzles. At least one inlet conduit is structured to deliver breathable gas into the frame and nozzle assembly for breathing by the patient. A pair of second connector portions are removably and rotatably connected to respective first connector portions of the frame and are in communication with respective inlet conduits, e.g., directly or via angle connectors. A headgear assembly is removably connected to the pair of second connector portions and/or the angle connectors so as to maintain the frame and the nozzle assembly in a desired adjusted position on the patient's face.

A respiratory mask for continuous positive airway pressure treatment includes a cushion adapted to be positioned against the face of a patient. The cushion is configured in a gasket arrangement around an entrance to the airways of the patient. The cushion is constructed from a polyurethane foam and has a thickness of greater than about 5 mm.

A nasal ventilation interface including a pair of tubes configured to deliver a ventilation gas. The tubes are attachable at a first end to a ventilation gas supply hose and engageable at a second end with a person's nostril. A coupler is configured to align the pair of tubes with the person's nostrils, wherein each tube has an absence of pneumatic interconnection with the other tube.

A respiratory mark assembly for delivering breathable gas to a patient includes a frame and a cushion. The cushion has a non-face contacting portion structured to be connected to the frame, a face-contacting portion structured to engage the patient's face, and an intermediate portion that interconnects the non-face contacting portion and the face-contacting portion. The intermediate portion includes a gusset portion that applies a first component of force to the patient's face through the face-contacting portion. A spring structure is coupled with the face-contacting portion of the cushion. The spring structure applies a second component of force to the patient's face through the face-contacting portion. The first and second components of force applied by the gusset portion and spring structure, respectively, determine a contact force of the cushion applied to the patient's face through the face-contacting portion. The intermediate portion may also include an elastic cuff portion. Further, in the case of an oral mask, the sealing section may include a portion that is designed to promote a better seal in the chin region of the mask.
