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 device for removal of a body fluid, such as a nasal fluid, and includes a collector vessel that traps and collects body fluid entrained in an air stream passing through the collector vessel. The collector vessel is made up of first and second bell shaped shell portions removably attached to one another and holding therebetween an internal, removable central member that temporarily reverses the direction and reduces velocity of the air stream.

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 ear nose and throat (ENT) imaging and analysis system includes an endoscope usable to capture images of the nasal canal and other aspects of patient anatomy. Endoscopic images may be presented to a user via a touchscreen display, and the software may provide different imaging modes that aid in identifying particular anatomical structures or areas within the nasal canal. In one mode, the system uses an object recognition process to identify the nasal valve opening within the images at a relaxed state, and during forceful inhalation, and then calculates the difference between the two states, which may be suggestive of nasal valve collapse. In other modes, the system is configured to identify abnormalities of the inferior turbinate, septum, or other anatomy, as well as empty spaces within the nasal canal, as well as areas and volumes of empty space and user defined boundaries.

A system for irrigating and cleaning nasal cavities is provided. In some embodiments, the system includes a stand configured to hold an aqueous solution container. A primary incoming tube leading to a face mask device configured to be worn by a user. In one embodiment, the solution is gravity fed directed through the primary incoming tube into at least one port of the face mask device. A drain line leads from the face mask device to a collection container.

A mask assembly or interface with a mask assembly includes a mask seal and a mask shell that supports the mask seal. In some configurations, the mask assembly is configured to be fully positioned lower than a bridge of a nose of a face of a user and to provide an exposed bridge of the nose of the user. The mask seal includes one or more features that decouple movement of the nasal portion and the oral portion to allow relative movement therebetween at least about a longitudinal axis extending in the front to back direction of the mask seal. In some configurations, an interface assembly includes a movement limiting arrangement that limits movement of the upper portion of the mask seal.

A nasal irrigation device communicates an irrigant to a device user and comprises a mechanics module and a reservoir assembly wherein a source of saline comprising a cartridge is disposed within the mechanics module adjacent a lid assembly for piercing the cartridge upon closing of a lid for releasing the cartridge contents into the reservoir assembly. A faux collapsible cartridge for testing operability of a nasal irrigation device comprises a housing including a shaft, a spring biased rod extending from the housing shaft, and a flange depending from a housing wall whereby the rod and flange are disposed to actuate a trigger assembly of the nasal irrigation device.

A deliver device for a compound including: a housing, vial holding a compound; and a source of propellant, wherein the housing provides an inlet and an outlet for the vial, wherein the inlet is in fluid communication with the source of propellant and is directed against the compound and the outlet allows for delivery of the compound.

A nasal delivery device for delivering substance to a nasal cavity of a subject, the delivery device comprising: a substance supply unit for supplying a dose of substance to be delivered to the nasal cavity of the subject, the substance supply unit including an inlet and an outlet; a nosepiece unit including a nosepiece for fitting to a nasal cavity of the subject and being in fluid communication with the outlet of the substance supply unit; and a mouthpiece unit including a mouthpiece in fluid communication with the inlet of the substance supply unit and through which the subject in use exhales such as to entrain substance from the container chamber and deliver the same through the nosepiece, and at least one temperature modifier for reducing a temperature of the exhaled air flow such as to reduce the absolute humidity thereof.
