Abstract: A headgear for attaching an object to a head of a user that is defined by a support beam and first and second ear loops coupled to opposite ends of the beam. The support beam generally wraps around a back of a user's neck or head and remains below the external occipital protuberance at all times during use of the headgear. This configuration minimizes the contact between the portions of the headgear and the user's hair. The first and second ear loops each include an upper arm adapted to be positioned above the ear, a lower arm adapted to be positioned below the ear, or both. An interface device is coupled to the headgear and held on the user's head by a tensioning force pulling the interface device toward the user.

Abstract: A pressure support system that comprises a patient circuit, a docking assembly, and a tank. The patient circuit delivers a pressurized flow of breathable gas to a patient. The docking assembly has an inlet and an outlet that is adapted to receive the pressurized flow of breathable gas, and is also adapted to be connected with the patient circuit. The tank is constructed and arranged to be removably connected with the docking assembly, and enables the pressurized flow of breathable gas to pass therethrough. The tank is also adapted to contain a liquid such that a humidity level of the pressurized flow of breathable gas is elevated as the pressurized flow of breathable gas passes therethrough.

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: A respiratory support system having a patient interface attached to a headgear assembly for delivering a gas to a patient is disclosed. The headgear provides a rigid member and a pad held in place on the patient's head by straps. The rigid member functions to prevent creep of the straps, distribute the strapping forces, and minimized tangential strap forces that otherwise squeeze the sides of the patient's head.

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.
