Abstract: A patient interface includes a cushion having a body with a front portion and a rear portion. The front portion has a lower opening structured to receive a flow of a treatment gas and a coupling mechanism. The rear portion is structured to engage a user's face and provide a generally continuous seal therewith. The patient interface further includes a frame having a torus shaped portion defining an opening. The opening has at least a portion of the coupling mechanism disposed therein.

Abstract: An interconnect assembly is for a pressure support system that includes a gas flow generator and a patient interface device fluidly coupled to the gas flow generator. The gas flow generator produces a flow of breathing gas for a patient. The interconnect assembly includes: a conduit fluidly coupled to each of the gas flow generator and the patient interface device, the conduit having a length, and an adjustment assembly including: a number of tension members each at least partially overlaying the conduit, each of the tension members being structured to move independently with respect to the conduit, and a winding apparatus connected to each of the tension members, the winding apparatus being structured to wind each of the tension members. When the winding apparatus winds the tension members, the length of the conduit decreases.

Abstract: A cushion (44) for a patient interface device (26) that has an inverted geometry. In particular, the cushion includes a support portion (56) having a first edge (60) and a second edge (62) located opposite the first edge, and a sealing flap (58) extending in a cantilevered fashion inwardly from an inner edge of the second edge of the support portion and toward the longitudinal axis (59) of the cushion.

Abstract: A cushion (26) for a patient interface device includes a support wall portion and a sealing flap (40) extending in inwardly from the support wall portion and toward a longitudinal axis of the cushion. The sealing flap has a distal edge (44)which defines an opening (46) in the sealing flap. The opening extends from the nose bridge to the upper lip and is created by two planes (hinged nearer the upper lip) that intersect at a large angle (e.g., 90 degrees to 150 degrees) near the upper lip.

Abstract: A cushion (26) for a patient interface device includes a support wall portion having a first edge and an opposite second edge, and a sealing flap (40) extending in a cantilevered fashion inwardly from the second edge and toward a longitudinal axis of the cushion such that when the patient interface device is donned a portion of the face of the user will engage the top outer surface of the sealing flap to form a seal. The sealing flap includes a corrugated portion (56), wherein the corrugated portion commences at a distal edge of the sealing flap and extends toward a proximal edge of the sealing flap along at least a portion of a width of the sealing flap. The corrugated portion includes a series of alternating furrows and ridges.

Abstract: A cushion (16) for use with a mask in delivering a flow of breathing gas to a user includes a first portion (38) adapted to be coupled to a mask shell (22), a second portion (36) adapted to contact a surface of a user, and a wall portion (40) extending between the first portion and the second portion. The second portion includes a septum region (50) and an alare region (52), the septum region being adapted to curl back a first distance (d1) from the user responsive to the cushion being donned by a user, and the alare region being adapted to curl back a second distance (d2) from the user responsive to the cushion being donned by a user, the first distance being greater than the second distance.

Abstract: A cushion (10, 30, 56) for a patient interface device includes a patient contacting portion (12, 32, 60) and wall portions (18, 20, 22, 24, 34, 66, 68, 70, 72). The wall portions include a plurality of voids (26, 74) and/or orifices therein. The patient contacting portion and the wall portions may be made of a material having a hardness of between 5 and 60 on the Shore 00 scale. Also, the parts of the wall not having the plurality of voids/orifices provided therein may have a cross-sectional thickness of 4 mm or greater. The voids may include a first void provided in an inner side of a first one of the wall portions and a second void provided in an outer side of the first one of the wall portions. The first void and the second void are positioned across from and overlapping one another.
