Abstract: A respiratory mask assembly for use with a patient, and that is suited for use with children ranging in age from about 2-7 years, includes a flexible patient interface structure arranged to interface with and deliver air to the patient's nose, the patient interface structure including cylindrical protrusions extending from respective opposite sides of the patient interface structure adjacent the patient's nares; a frame configured to support the patient interface structure, the frame including a pair of cylinders, each cylinder configured to receive a respective cylindrical protrusion of the patient interface structure; headgear arranged for releasable attachment to the frame; an air delivery tube connected to either one of the cylindrical protrusions; and a plug connected to the other one of the cylindrical protrusions.

Abstract: A supplemental gas delivery device is described for a mask assembly having at least one supplemental gas port, the at least one supplemental gas port including an aperture in communication with an interior of the mask assembly. The mask assembly may include an aperture communicating with an interior of the mask assembly, and a cannula for communicating with the supplemental gas port. The cannula is positioned to deliver supplemental gas adjacent to the patient's nares and/or mouth, to increase an efficacy of treatment for the patient by more directly applying the flow of supplemental gas to the patient's nares. An optional bridging portion may be included to provide a connection between supplemental gas port and the cannula.

Abstract: A patient interface includes a frame assembly (16100) including connectors operatively attachable to headgear, a cushion assembly (16175) including a shell (161800) and a seal-forming structure (16200) structured to form a seal with the patient's nose and/or mouth, and an air delivery connector (16600). The cushion assembly and air delivery connector are structured to releasably connect to the frame assembly independently of each other. A static face seal and separate static diametric seal between the shell (161800) and frame (16100). A dynamic face seal and separate dynamic diametric seal between the air delivery connector (16600) and frame (16100). Separate claims (FIG. 6) to a frame assembly (16100) with upper headgear connector arms (16134) including at least one slot (6146) (claim 17) or flexible portions (claim 22) to form hinges structured and arranged to conform to varying facial profiles.

Abstract: A mask system for treating sleep disordered breathing. The mask system includes headgear and a combination shell and cushion. A plurality of ribs provide rigidity to the combination shell and cushion and are formed integrally with the combination shell and cushion. The mask system also includes a frame shaped and adapted to be removably mounted on the combination shell and cushion. The frame has a plurality of headgear anchor points. A retaining ring is positioned adjacent the front aperture. In addition, a rotatable elbow has a proximal end, a distal end and circumferentially equi-spaced diametrically opposed tongues with undercuts. The proximal end is adapted to pass through the retaining ring. The distal end is adapted to engage an air delivery tube, and the undercuts are adapted to engage the retaining ring. Also, a seal allows rotation of the rotatable elbow relative to the combination shell and cushion.

Abstract: A mask assembly suitable for the treatment of sleep disordered breathing may include a mask to provide pressurized air to a patient; upper and lower slot features located on each side of the mask; a headgear assembly including a back portion; a pair of upper straps provided to the back portion, each upper strap having a loop portion and a hook portion at a free end thereof for releasably attaching to the loop portion; a pair of lower straps extending away from the back portion, each lower strap having a loop portion and a hook portion at a free end thereof for releasably attaching to the loop portion; and a connection region of each loop portion of each strap, the connection region being adapted to receive a respective hook portion, the connection region being wider than each respective hook portion along each respective hook portion's entire length.

Abstract: A mask system for treating sleep disordered breathing, comprising headgear, a shell/cushion including a channel adjacent a front aperture, a frame, an elbow including at least one undercut on a proximal end, a retaining ring including a rear flange adapted to be retainably insertable in the channel of the shell/cushion, and a front flange adapted to retainably engage with the at least one undercut of the elbow.

Abstract: An elbow assembly for use in a respiratory mask, which includes an elbow, an inlet port, an exhaust port, and a baffle separating the inlet port from the exhaust port. A mask assembly includes a cushion comprising at least one gusset and an aperture for connection to the elbow assembly.

Abstract: A mask assembly adapted for use with a positive airway pressure device, includes a mask frame, an elbow assembly provided to the frame, a cushion provided to the frame, a forehead support assembly, and a neck to connect the frame to the forehead support assembly, wherein the neck includes a pair of side walls having a streamlined design that is made to look sleek and reduce or minimize obtrusiveness. The pair of side walls may take the form of a single wall or more than two walls. The mask frame may include a recessed port structure including at least one port having access to an interior of the frame which at least in part with the cushion defines a breathing chamber in communication with a nasal passage of the patient in use. The mask frame may also include a channel to receive the cushion. The channel is formed by an outer wall and an inner wall and the channel includes an inner surface having a bead to engage with an outer surface of an edge of the cushion.

Abstract: A mask assembly includes a mask frame including a lower portion and a neck extending from the lower portion, a cushion provided to the mask frame and adapted to contact a patient's face, a forehead support assembly provided to the neck of the mask frame, the forehead support assembly including a forehead support and a forehead pad provided to the forehead support, and an elbow assembly provided to the mask frame. The neck includes a pair of side walls spaced apart from one another along an entire length of the neck, the side walls providing an open space therebetween along the entire length of the neck that opens towards a front side of the mask assembly. The pair of side walls comprise an upper converging section wherein the pair of side walls converge towards one another in a downward direction.
