Respiratory assembly for use in conjunction with a continuous positive airway pressure (CPAP) equipment is provided. The respiratory assembly includes a conduit coupler comprising a male member and a female member. The respiratory assembly also includes a disposable respiratory mask that defines a central opening therethrough that is sized to receive the male member. A gasket is positioned between the male member and the respiratory mask, the gasket encircling the central opening to provide a sealing thereto. A channel opening of one of the male member and the female member connects to a continuous positive airway pressure (CPAP) mask that couples to one or more of a patient's nare and mouth.

Devices and methods for adaptively generating facial device selections based on visually determined anatomical dimension data. The device may include a processor and a memory. The memory may include processor-executable instructions for receiving image data representing a user face and determining anatomical dimension data associated with a nasal-oral region of the user face based on the received image data. The processor-executable instructions may be for generating one or more facial device recommendations based on a recommendation model and the anatomical dimension data and providing the one or more facial device recommendations for display at a user interface.

A patient interface may have a frame and a seal-forming structure. The frame may at least partially form a plenum chamber pressurisable to a therapeutic pressure. The seal-forming structure may be constructed and arranged to form a seal with a region of the patient's face surrounding an entrance to the patient's airways, said seal-forming structure having a hole therein such that the flow of air at said therapeutic pressure is delivered to at least an entrance to the patient's nares, the seal-forming structure constructed and arranged to maintain said therapeutic pressure in the plenum chamber throughout the patient's respiratory cycle in use. The seal-forming structure may comprise a textile seal member adapted to sealingly engage the patient's face in use.

An interface for positive pressure therapy includes a mask assembly. The mask assembly includes a mask seal that is adapted to underlie the nose. The mask seal extends up the lateral sides of the nose. The mask seal has a primary seal below the nose and a secondary seal alongside the nose. The mask seal includes a rolling hinge that permits one portion of the mask seal to deform relative to another portion of the mask seal. In one configuration, the portion of the mask seal that underlies the nose is configured to deform relative to a lower portion of the mask seal.

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 model selection method for a negative pressure face mask assembly, and a model selection apparatus. The model selection method includes: obtaining an interval distance between both earlobes of a patient, and determining a width of the negative pressure face mask assembly according to the interval distance; obtaining a perimeter of a neck of the patient, and determining a curvature of a side of the negative pressure face mask assembly in contact with the patient according to the perimeter; and determining a model of the negative pressure face mask assembly according to the width and the curvature. The model selection method is able to precisely determine the model of the negative pressure face mask assembly that suits the patient.

Devices, systems, and methods for detecting a sealing condition between a patient interface and a patient, and adjusting the patient interface to maintain the patient interface in sealing contact with the patient. The patient interface may include a sealing structure to form a seal on the patient, and a positioning structure to secure the sealing structure to the patient. The patient interface may include a sensor coupled to the sealing structure. A processor determines the sealing condition between the sealing structure and the patient based on a signal from the sensor, and adjusts at least one of the sealing structure and the positioning structure to maintain the sealing structure in sealing contact with the patient. A prediction system predicts a leak between the sealing structure and the patient based on the sensor signal. A learning system learns how to fit the sealing structure to the patient to form a seal.

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.
