Abstract: A patient interface assembly that includes a first conduit, a second conduit, and a patient interface coupled to the first conduit and the second conduit. The first and second conduits each include a first end that is disposed proximate to a top of a head of a user, and a second end that is disposed proximate to an airway of such a user when the patient interface assembly is being worn by the user. The first and second conduits also each include a central portion that extends along the sides of a face between the user's eye and an ear a head strap is coupled between the first and second conduit, and a patient interface is coupled to the second ends of the first and second conduits.

Abstract: A pressure sensitive valve device for use with respiratory equipment of the type that produces a pressurized flow of breathing gas. The valve device combines the exhalation and entrainment functions in one valve with a single air path. The valve device provides an exhaust valve function during normal operation and provides a less restricted access to the ambient atmosphere in the event of respiratory equipment malfunction. The valve device includes a valve element that moves between at least two positions. During normal operation, when the pressure generating system is generating a flow of gas, the valve element is in a “closed” or “exhaust valve” position. When in the exhaust valve position, the gas flow to the atmosphere is restricted without being completely blocked off. When the flow of gas is decreased or interrupted, the valve element moves to the “entrainment valve” or “open” position that allows a greater, i.e., less restricted flow, of gas between the user and the ambient atmosphere.

Abstract: A patient interface assembly that includes a substantially rigid support and a patient interface device coupled to a first end of the support. A first arm is coupled to a first side of the support and a second arm is coupled to a second side of the support. A cross member spans between the first arm and the second arm such that the cross member is disposed under a patient's mandible when the patient interface assembly is worn by a user. An addition, a conduit is coupled to a second end of the support.

Abstract: The present invention provides a connection device for connecting a headgear having straps, a mask and a system for supplying a flow of gas to a patient. The connection device incorporates a locking member or locking portion which is configured to lock the straps in a particular location.

Abstract: A pharyngeal airway adjuster, or mandible positioning device, has a maxillary dentition engagement component and a mandibular dentition engagement component, each on opposite sides of a plane extending therebetween. An adjustable connection couples the maxillary dentition engagement component with the mandibular dentition engagement component. The adjustable connection has a first adjustment screw having a longitudinal axis parallel to the plane and a second adjustment screw having a longitudinal axis perpendicular to the plane. The first and second adjustable screws are independently adjustable and structured to effect horizontal and vertical displacement, respectively, of the maxillary dentition engagement component relative to the mandibular dentition engagement component.

Abstract: A patient interface system having a patient interface and chin support system for supporting the patient interface on the patient and for supplying a flow of gas from a patient circuit to the patient interface. In one embodiment, the chin support is formed from flexible hollow chambered support and extends from either side of the patient interface curving downwardly in front of the patient's cheeks, around the outside of the patient's mouth, to a position beneath the patient's mandible. In another embodiment, the chin support is coupled to a conduit that is coupled to the patient interface. The chin support includes at least a portion that is disposed under the patient's mandible.

Abstract: A connection device for connecting a headgear and a mask and a system for supplying a flow of gas to a patient that incorporates such a connection device. The connection device allows independent rotation of each of two independently disconnecting headgear connectors. The gas delivery mask includes a shell, a first connector associated with the shell, a second connector connected to a headgear and realeasably and rotateably connected to the first connector.
