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.

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 assistive device for a metered dose inhaler decreases the force required to operate the inhaler. The assistive device has a body with a passage for receiving a replaceable conventional metered dose inhaler assembly that has a canister and a transverse mouthpiece with an axis of the canister aligning approximately with that of the passage. At least two symmetrically arranged levers extend in a direction away from the body and parallel to an axis thereof. A proximal end of each lever is attached to the body such that the free opposite ends of the levers may be moved towards and away from each other. An inwardly directed cam surface on each of the lever exerts a force on an end of the canister in use to move the canister longitudinally to cause a dose of medicament to be dispensed from the canister. An optional dose counter may form part of the device.

The embodiment relates to systems and methods structured to deliver acoustic and visual energies to be received by living beings, and, more particularly the energies received by living beings can be configured, composed, and/or designed to be delivered to address a plurality of conditions including enjoyment. The energies can be deployed by using various algorithms and can include tones, tuning, rhythms, sound waves, harmonies, melodies, chord progression and instrument arrangement to deliver the energies preferentially to different parts of a living being's body, such as but not limited to, right and/or left ears. The algorithms can include variations in Pythagorean tuning and just and pure intonation, monaural and binaural beats for brain wave entrainment, Solfeggio Frequencies, Fibonacci Sequencing, and/or carrier waves and isochronic tones.

The disclosed invention provides a skin therapy system for skin conditioning or treatment of a body part. The skin therapy system includes a body part shaped encaser including a first and second film substrate and an encaser liner disposed between the first and second film substrates. An outer peripheral edge of the encaser liner is sealed between outer peripheral edges of the first and second film substrates to create a hermetic seal forming a first fillable space between the first film substrate and a first layer of the encaser liner, a second fillable space between the second film substrate and a second layer of the encaser liner, and an internal volume defined by the first and second layers of the encaser liner and disposed between the first and second fillable spaces. The skin therapy system further includes a therapeutic composition contained within the first and second fillable spaces.

An air delivery system for providing a supply of air from a source of air at positive pressure to an interfacing structure located at the entrance to the airways of a patient includes a manifold adapted to connect with the supply of positive air pressure and at least one tube connected to the manifold and adapted to deliver the supply of air to the interfacing structure. Each tube is structured to allow movement between an open phase in which the tube allows the passage of air and a collapsed phase in which the tube is collapsed. Each tube is structured such that weight of a typical patient's head against bedding apparel is sufficient to collapse the tube from the open phase to the collapsed phase.

A breathing mask for use in administering inhalable medications to a patient in need of an inhaled drug is provided. The mask disclosed herein is particularly useful for use with very young children. The mask is made from a flexible molded plastic silicone or elastomeric material, and has an anthropometrically/anatomically/ergonomically contoured shape to provide a good seal, a comfortable fit, and minimal dead space within the mask. The airway is aligned with nose. There may be an orifice for use with a soother device to calm a child using the mask. Also provided is a visual flow indicator to provide an indication of the quality of the seal of the mask on the face.

A respiratory interface device is provided that includes a cushion and a faceplate. The cushion is structured to be coupled to the faceplate. The faceplate includes a peripheral end and a number of custom features. The cushion is coupled to the faceplate adjacent the faceplate peripheral end.

A PAP system includes a PAP device to generate a supply of pressurized air, a patient interface adapted to form a seal with the patient's face, air delivery tubing to interconnect the patient interface and the PAP device, and a cover that substantially encloses at least a portion of the PAP device and a portion of the air delivery tubing. The cover allows the PAP device to be carried by and/or supported on the patient's head.
