At least a portion of the first lateral side member and the second lateral side member is rigid or semi rigid.

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 garment having a tubing management system incorporated therein is provided. The tubing management system includes at least one conduit and a coupling system for the conduit. The coupling system has at least one coupling point, which is located, for example, at the neck opening of the garment. The coupling system defines a path for the conduit, i.e., there is more than one attachment point, therefore the path of the conduit may be controlled. In this configuration, the conduit moves with the user and, as such, there is a reduced chance that the user's movements, even while asleep, will cause the facemask to be pulled from its proper position.

Abstract: A fluid flow control apparatus for use in, for example, a patient interface, is provided that includes a main conduit structured to receive a pressurized fluid and a nozzle assembly coupled to the main conduit. The nozzle assembly includes an external nozzle element having a contoured top surface and a main bore in fluid communication with an interior of the main conduit, an internal nozzle element received within the main bore, wherein a gap is provided between the internal nozzle element and the external nozzle element, and a switching element selectively moveable between a first position and a second position, wherein in the first position, the switching element is positioned below the contoured top surface of the external nozzle element, and wherein in the second position, at least a portion of the switching element is positioned adjacent to or above the contoured top surface of the external nozzle element.

Abstract: An apparatus for indicating a strapping force applied by a headgear of a patient interface device. The apparatus includes a first portion structured to be selectively connectable to a connecting element of a mask of the patient interface device, a second portion structured to be selectively connectable to a strap of the headgear, and a force gauging mechanism coupled to the first portion and the second portion. The force gauging mechanism is structured to gauge and indicate a force being applied by the headgear in response to the second strap portion being pulled by the strap of the headgear.

Abstract: A patient interface device includes a mask having a shell defining a chamber. A component, such as a nasal cannula coupled to a sensor, is structured to be selectively positioned within the chamber.

The manipulation mechanism may include an attachment element, such as a magnet, attached to the component and structured to be selectively positioned on the interior surface of the shell, and a manipulation element, such as a magnet, structured to be selectively positioned on the exterior surface of the shell and coupled to the attachment element through the shell, wherein movement of the manipulation element causes movement of the attachment element and the component.

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 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, 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. In a further embodiment, a pair of rigid connecting members couple the patient interface device to the headgear.

Abstract: A patient interface device includes a support structure, a pivot arm pivotably coupled to the support structure and structured to pivot about an axis, a patient coupling member, such as a mask or a forehead support, coupled to the pivot arm, and a cam wheel rotateably coupled to the support structure and engaging the pivot arm, wherein rotation of the cam wheel relative to the support structure and the pivot arm causes the pivot arm to pivot about the axis and the patient coupling member to move either forward or backward along a path of movement. Also, an alternative patient interface device includes a cam wheel rotatable about a cushion member that changes a position of a main body portion of the cushion member relative to a headgear frame member of the patient interface device.

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.
