This application relates to a patient interface and headgear for a breathing apparatus. The patient interface includes a headgear, such as a nasal cannula. The interface has a flexible face mount and a more rigid gas flow manifold component. The flexible face mount has a nose fork and a base portion, while the more rigid gas flow manifold component has an inlet and an outlet. Gas is delivered into the manifold inlet and flows out through the outlet and into the base portion of the face mount. The outlet of the manifold component includes a groove that creates a gap between the base portion of the face mount and the manifold component in an area adjacent to the philtrum, thereby providing pressure relief on the nasal septum. The headgear has a strap. The portion of the headgear that contacts the face has a surface area for frictionally engaging with the skin. The material in these areas can be in the form of a sleeve, coating, or overmolded. The remaining portion of the strap has a different material property than the portion that contacts the face.

A wearable device for being worn on a nose of a person comprises a main body 10 configured to be coupled to the septum of the nose. A first sensor housing 21, fixed to the main body, comprises a first sensor unit, which is configured to detect an airflow out of a first nostril, and detect airflow into the first nostril. The device may comprise a first sensor to measure airflow out of the first nostril and a second sensor to measure airflow into the first nostril. The first sensor housing may be configured to divert the flow path of air flowing out of the first nostril away from the second sensor, and may divert the air flowing into the first nostril away from the first sensor. The sensors may comprise temperature, humidity, heart rate and / or pressure sensors. A processor may calibrate the first sensor unit based on the nasal shape of the user, and may adjust the sampling rate of the first sensor unit based on the noise of the data obtained. Fig. 5

A nasal dilator device comprises a substantially U-shaped body including a central portion arranged to span a septum of a nose when worn by a user and first and second leg members extending from the central portion in a first plane, a first cantilever rib member extending outward from the U-shaped body in a second plane and a second cantilever rib member extending outward from the U-shaped body in a third plane, wherein the first and second cantilever rib members extend away from each other. The nasal dilator device further comprises a first intermediate section connecting an end of the first leg member to a proximal end of the first cantilever rib member, wherein the first intermediate section extends from the first plane to the second plane; and a second intermediate section connecting an end of the second leg member to a proximal end of the second cantilever rib member, wherein the second intermediate section extends from the first plane to the third plane and at least one projection protruding from and extending along at least a portion of a length of each of the first and second cantilever rib members.

The invention relates to a patient interface and headgear for a breathing apparatus. A patient interface having a headgear, such as a nasal cannula. The interface has a soft face mount part having a nose prong and a base portion and a gas flow manifold part of harder material having an inlet and an outlet. Gas is passed into the manifold inlet and flows out through the outlet and into the base portion of the face mount. The outlet of the manifold part includes a groove that provides a gap between the base portion of the face mount and the manifold part adjacent an area in the person, thereby providing pressure relief on the nasal septum. The headgear has a lace. A portion of the headgear contacting the facial area has a surface area for frictionally engaging with skin. The material in these regions may be in the form of a sleeve or coating or overmold. The remaining portion of the lace has a different material property than the portion in contact with the facial region.

This invention discloses a miniature glasses-style nasal mask, relating to the field of respiratory protective equipment. The nasal mask includes: a frame, an inner tube, an outer tube, filter cotton, a fixing cap, and a one-way valve. The frame is integrally formed in a sheet shape. The two temples form an angle of ≤15 degrees with the inner tube to clamp the sides of the nose, and the two inner tubes clamp the nasal septum, working together to ensure the nasal mask fits snugly and is not easily dislodged. The inner and outer tubes are located on the inner and outer sides of the frame, coaxial, and integrally connected. A one-way valve is located inside a thin tube with a cover and side holes protruding from the root surface of the outer tube. The inner tube is short and fitted with a thin latex tube, which is inserted into the nostril and seals the nasal cavity. The filter cotton is conventional, round, and has the same cross-section as the outer tube opening. The fixing cap presses the filter cotton to seal the outer tube opening and is preferably fixed to the outer tube opening by screwing. A round hole is opened at the center of the cap. Beneficial effects: Air is inhaled through the filter cotton and exhaled through the one-way valve, ensuring unobstructed breathing; easy to seal and fill, the whole structure is not easily dislodged, miniature and simple, with a simple structure and low cost.
