Abstract: A patient interface of the present invention includes a faceplate including a plurality of headgear attachment elements, a seal member operatively coupled to the faceplate; and an adjustment mechanism coupling the seal member to the faceplate. The adjustment mechanism controls the position of the seal member relative to the faceplate such that the seal member is moveable from a first position to a second position and is maintained in the second position during use of the patient interface after being moved to the second position.

Abstract: A respiratory mask is provided having an outer shell coupled to a cushion for the delivery of a gas to a user. The cushion of the respiratory mask has at least one pleat disposed in the cushion in order to provide varying degrees of flexibility and support about the cushion.

Abstract: A patient interface device includes a support member, a sealing assembly attached to the support member, and a pair of contacting members. The contacting members are coupled to the support member on each side of the sealing assembly. The contacting members are each configured and arranged to contact the user over a limited contacting region, which corresponds to a junction of the orbicularis oris facial muscle, the zygomaticus facial muscle, and the risorius facial muscle.

Abstract: A patient interface assembly that includes a patient interface device, a headgear, and pivoting coupling member joining the interface device to a headgear assembly. In one embodiment, a spring biases the patient interface device against the patient's face when in use. In a further embodiment, the patient interface device is a nasal cushion that includes a formable support mounted to the nasal cushion for providing support and adjustment of the nasal cushion to improve fit and comfort. The headgear assembly in one embodiment is a semi-rigid, minimal contact harness assembly and includes an adjustment assembly that allows for a simultaneous adjustment of multiple straps. In a further embodiment, a pair of rigid connecting members couple the patient interface device to the headgear.

Abstract: A respiratory mask is provided having an outer shell coupled to a cushion for the delivery of a gas to a user. The cushion of the respiratory mask has a pleat and varied wall thicknesses about the device in order to provide varying degrees of flexibility and support about the cushion.

Abstract: A flexible connector that couples a delivery conduit to a patient interface device and a pressure support system that includes such a flexible connector. The flexible connector of the present invention prevents disruption of the seal between the patient interface and the patient's face. The flexible connector may have a bellows portion with a longitudinally directed portion, a narrowed neck portion, or a plurality of corrugations. The flexible connector may further have a swivel portion and/or an exhaust member, and/or a hinge member.

Abstract: A patient interface device that includes a body portion comprising a pair of arms and a chin support. A first end portion of each arm in the pair of arms is coupled to an opposite end of the chin support. The chin support is adapted to be disposed under the mandible responsive to the patient interface device being donned by a user. At least one headgear attachment element is provided on each arm in the pair of arms. A circuit portion is provided at a second end portion of each arm in the pair of arm. A patient interface portion is coupled to the circuit portion.
