A mask for use in providing a flow of a treatment gas to the airway of a user. The mask includes a frame and a conformable seal which is structured to sealingly engage about at least one of at least a portion of nose or mouth of the user. The frame includes a front face and a concave shaped rear face which faces the user when the mask is disposed on the user's face. The rear face defines a cavity which is structured to receive at least one of a portion of a nose and/or mouth of the user therein. The frame also includes a number of deformable zones, each deformable zone being structured to receive a removable insert. Each deformable zone is structured to adapt to at least one of a size or shape of the removable insert received therein.

A method for identifying a mask for a patient includes: receiving a plurality of images of a patient's face; analyzing the plurality of images to generate a temporal model of the patient's face, determining a mask for the patient using the temporal model of the patient's face, and identifying the mask to the patient.

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 mask system for use between a patient and device to deliver a breathable gas to the patient includes a mouth cushion, a pair of nasal prongs, an elbow, and a headgear assembly. The mouth cushion is structured to sealingly engage around an exterior of a patient's mouth in use, and the pair of nasal prongs are structured to sealingly communicate with nasal passages of a patient's nose in use. The elbow delivers breathable gas to the patient. The headgear assembly maintains the mouth cushion and the nasal prongs in a desired position on the patient's face. The headgear assembly provides a substantially round crown strap that cups the parietal bone and occipital bone of the patient's head in use.

A system for reducing airway obstructions of a patient may include a ventilator, a control unit, a gas delivery circuit with a proximal end in fluid communication with the ventilator and a distal end in fluid communication with a nasal interface, and a nasal interface. The nasal interface may include at least one jet nozzle, and at least one spontaneous respiration sensor in communication with the control unit for detecting a respiration effort pattern and a need for supporting airway patency. The system may be open to ambient. The control unit may determine more than one gas output velocities. The more than one gas output velocities may be synchronized with different parts of a spontaneous breath effort cycle, and a gas output velocity may be determined by a need for supporting airway patency.

A respiratory assembly is provided. The assembly includes at least one post having a nasal engaging portion on about a first end thereof for delivering treatment gases to the nasal cavity of a patient. A pair of tubes capable of receiving gas from a hose or fluid source are selectively engaged with the pair of posts for delivering treatment gases from the inlet through the receptacle and into the nasal cavity of the patient. A splitter may be positioned between the hose or fluid source and the pair of tubes. Ball and socket joints may provide enhanced flexibility of the assembly while in use.

In one embodiment, a wearable assembly that includes a plurality of components is provided. The components include an eyepiece assembly fittable over a portion of a wearer's face, the eyepiece assembly including one or more strands, at least a portion of the eyepiece assembly including a phase change material, wherein a shape of the eyepiece assembly changes upon an application of an energy to the phase changing portion to one or more of conform and contour to one or more features of the wearer's face; and nosepiece connected to the eyepiece assembly.

A system and method to match an interface to the face of a user for respiratory therapy. A facial image of the user is stored. Facial features based on the facial image are determined. A database stores facial profiles based on facial features and a corresponding plurality of interfaces. A database stores operational data of respiratory therapy devices with the plurality of corresponding interfaces. A selection engine is coupled to the databases. The selection engine is operative to select an interface for the user from the plurality of corresponding interfaces based on a desired outcome based on the stored operational data and the facial features. The collected data may also be employed to determine whether the selected interface is correctly fitted to the face of the user.

A facemask configured to be used by multiple sized/shaped heads can include a primary, a secondary and a tertiary seal. In some embodiments, the primary seal is contact with the nose and cheek regions; the secondary seal is in contact with the chin region; and the tertiary seal is in contact with the cheek and chin regions. In some embodiments, the tertiary seal extends inwardly and outwardly when applied to the face. In some embodiments, the mask includes test scissors.

A patient interface comprises a plenum chamber and a seal-forming structure. The seal-forming structure comprises a support structure arranged to support a sealing portion that is adapted to sealing engage the patient's face in use. The seal-forming structure may also include a seal biasing portion configured to inflate under pressurization within the cavity in the cushion assembly in use to extend the reach of the sealing portion and decouple the sealing portion from external forces.
