A method of creating a 3D model of a physical object includes adaptively and iteratively generating a number disparity maps from image data representing a plurality of images of the physical object iteratively captured by a plurality of cameras having electrically adjustable focal lengths by varying at least one of the focal lengths of the plurality of cameras and a distance of the physical object from the plurality of cameras during capture of the images until one of the disparity maps is determined to have a least a threshold level of disparity, and converting the one of the disparity maps into the 3D model.

The present invention provides materials and methods for forming an interface between an appliance and living tissue using a foamed elastomeric material which contacts the tissue or similar surfaces. The elastomeric material is in the form of a durable and washable material that, when applied to or implanted in living tissue or similar surfaces, displaces and flows in to non-conforming areas creating an air and/or water tight seal that substantially returns to an original shape when removed from the contact surface. The appliance may also include structural elements designed to optimize comfort, compliance and seal achieved through minimizing the pressure variation along the contact surface of the therapy device.

A patient interface comprises a support structure and a seal-forming structure. The support structure is arranged to support the sealing portion and is configured to connect to the frame. The sealing portion comprises textile and is attached to the support structure along an outer perimeter of the sealing portion such that in use the sealing portion may be in tension due to reactive stress of the support structure and/or a resilient stretch characteristic of the textile such that the sealing portion exerts a force against the patient's face.

An ostomy pouching system is described. A baseplate includes a seal adapted to be securely placed on the skin about the perimeter of tissue defining a stoma incised into a patient. An ostomy reservoir forms a sealed space within which discharge can be received and held. A flex layer includes a seal that is airtight, watertight, or both, and which is structurally interposed between at least a portion of two or more of the skin, tissue, stoma, baseplate, and ostomy reservoir. The flex layer includes a resiliently and elastically malleable phase change material. The flex layer is deformable such that at least one portion of the flex layer can transmute the magnitude of a force applied to the flex layer and redirect the force. External forces acting upon at least one of the skin, tissue, stoma, baseplate, and ostomy reservoir are mitigated, transmuted, and isolated by the flex layer.

A method of determining facial metrics of a patient includes: capturing a first image of the patient with an image capturing device positioned in a first known position with the assistance of a positioning device, capturing a second image of the patient with the image capturing device positioned in a second known position different that the first known position with the assistance of the positioning device, and determining facial metrics of the patient by analyzing the first image and the second image.

A patient interface is disclosed which is comfortable for the user to wear and includes at least in part a moisture permeable or breathable area in the body of the patient interface. In another embodiment the patient interface is a strapless mask that is moulded to fit the contours of a user's face and maximise the mask-to-skin seal. An adhesive material is bonded to the mask cushion and is stamped in place to form substantially the same shape as the cushion such that it fits the facial contours of the user.

Device, systems, and methods relating to a mask interface are disclosed. For example, a mask interface may include a body and an interface coupled to the body. The body may include a nasal portion including an opening and a mouth portion including an open channel. The interface may be in contact with a subject’s face and may include a flexible material conformable to the subject’s face.

A patient interface comprising a plenum chamber configured to receive in use a flow of air at the therapeutic pressure for breathing by a patient, a seal-forming structure configured to form a seal with or around the patient's nose and/or mouth, a positioning and stabilising structure configured to hold the seal-forming structure in a sealing position, and at least one inflatable body. In one form, an inflatable body is provided to a portion of the positioning and stabilising structure. In another form the inflatable body is provided to a hoop structure. In another form, the patient interface comprises a lever arrangement, wherein an inflatable body is provided to the lever arrangement. In yet another form, the seal-forming structure comprises an inflatable body. The patient interface may be configured to limit or prevent mouth leak or mandible movement during CPAP therapy, adjust the fit of the positioning and stabilising structure on the patient's head, and/or improve the seal formed with patient's face in use.

A conduit for delivering a supply of gas under a positive pressure includes a conduit wall having a first conduit end and a second conduit end. The first conduit end is adapted to be attached to the supply of gas. The conduit wall is deformable between (a) an open condition in which the conduit wall defines a conduit passage along which the supply of gas can travel between the first conduit end to the second conduit end, and (b) a collapsed condition in which the conduit wall substantially collapses the conduit passage.

A shroud for a mask system includes a retaining portion structured to retain a frame, a pair of upper headgear connectors each including an elongated arm and a slot at the free end of the arm adapted to receive a headgear strap, and a pair of lower headgear connectors each adapted to attach to a headgear strap. The retaining portion, the upper headgear connectors, and the lower headgear connectors are integrally formed as a one piece structure.
