A respiratory mask assembly for delivering breathable gas to a patient includes a frame and a cushion. The cushion has a non-face contacting portion structured to be connected to the frame, a face-contacting portion structured to engage the patient's face, and a central portion that interconnects the non-face contacting portion and the face contacting portion. The frame may be structured to allow a forehead support to assume multiple positions, to compensate for replacement cushions that may have a different profile, shape or size. The cushion is structured to compensate for variations in strap tension, treatment pressure and/or movement of the patient. Headgear may be provided with a strap assembly in which one or more straps is provided with selectively adjustable elasticity or extensibility that may be automatically changed in dependence of treatment pressure and/or treatment type.

The forehead support has a hinge so that the forehead support can be deformed to conform to the user's forehead. The patient interface also has a pivotable coupling defined by a body and a coplanar conduit that extends radially from the body. The coupling also has a port that allows access within the cavity formed by the cushion so that the port and coupling may rotate together.

Methods and systems for automatically generating a mask delineating a region of interest (ROI) within an image containing skin are disclosed. The image may be of an anatomical area containing skin, such as the face, neck, chest, shoulders, arms or hands, among others, or may be of portions of such areas, such as the cheek, forehead, or nose, among others. The mask that is generated is based on the locations of anatomical features or landmarks in the image, such as the eyes, nose, eyebrows and lips, which can vary from subject to subject and image to image. As such, masks can be adapted to individual subjects and to different images of the same subjects, while delineating anatomically standardized ROIs, thereby facilitating standardized, reproducible skin analysis over multiple subjects and/or over multiple images of each subject. Moreover, the masks can be limited to skin regions that include uniformly illuminated portions of skin while excluding skin regions in shadow or hot-spot areas that would otherwise provide erroneous feature analysis results. Methods and systems are also disclosed for automatically registering a skin mask delineating a skin ROI in a first image captured in one imaging modality (e.g., standard white light, UV light, polarized light, multi-spectral absorption or fluorescence imaging, etc.) onto a second image of the ROI captured in the same or another imaging modality. Such registration can be done using linear as well as non-linear spatial transformation techniques.

A face mask support for CPAP comprising a hemispheric cap with biasing means support at the medial line of the head. The circumferential edge of the cap extends from the high forehead to below the inion protrusion at the nape of the neck. A biasing means which is preferably of a length of spring steel is formed so as to extend from the biasing means support to form a loop around a face mask. The biasing means may be adjusted to accommodate facial configurations and to vary the pressure with which the face mask is apposed to the face. In an alternative embodiment, the support is open and is comprised of a circumferential band extending from the middle of the forehead to below the inion protrusion and a medial band extending along the medial line of the head and connecting to the circumferential band at the middle of the forehead and below the inion protrusion.

The resilient hooks of the face shield are engaged with the respective shield couplings of the forehead cover.

The present invention discloses an adjustable forehead support for a nasal or full-face mask wherein the forehead support may be adjusted for the different shapes and sizes of a facial profile. The forehead support utilizes a dual-arm system that adjusts the position of the forehead support vis-á-vis the mask and/or airflow tube. The angle of the mask to the face may be adjusted with the present invention.

A body rest structure includes a torso support for supporting the torso of a human body in a prone, elevated position which serves to induce a mild stretch of the user's thoracic and lumbar vertebrae. The torso support includes an upper chest and shoulder support platform and a lumbar support platform. An open region extends longitudinally between the platforms to provide room for at least a portion of the weight of the chest below the shoulders to pull down on the body between the platforms. The support may include a rear supporting surface to provide lifting support from below the hips and abdomen of the body. A head support for supporting the head of the body in a downwardly facing position when the torso is supported by the torso support is also disclosed. The head support includes a front portion for providing lifting support to the forehead of the body, and parallel opposed side portions for supporting opposed sides of the face. Each side portion has an upper surface that slopes upwardly from the front portion of the head support to the associated distal end of the side portion.

A respiratory mask assembly includes a frame and a forehead support secured to the frame. The forehead support includes a joining member secured to an upper portion of the frame and a cushion frame movably mounted to the joining member. One of the joining member and cushion frame includes a pair of shafts and the other of the joining member and cushion frame includes a pair of openings. The pair of shafts are respectively received in the pair of openings to couple the cushion frame to the joining member and enable the cushion frame to move relative to the joining member.
