A vent for venting exhaust gases from a component of a respiratory therapy system. The vent may include a substrate having an inner surface and an outer surface. The vent may include at least one vent holeextending through the substrate and having a vent hole circumference. The vent hole may include an exhaust gas inlet at the inner margin of the substrate and an exhaust gas outlet at an outer margin of the substrate. The vent hole may include a sidewall extending between the exhaust gas inlet and the exhaust gas outlet. The exhaust gas inlet and the exhaust gas outlet have different diameters such that the sidewall of the vent hole is inclined at an angle of inclination between the exhaust gas inlet and the exhaust gas outlet. The angle of inclination of the inclined side wall of the vent is non-constant around the vent hole circumference.

Vent for a component of a respiratory therapy system

A mask assembly can include a mask seal. In some configurations, the mask assembly can be 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 can comprise a nasal region comprising at least one nasal opening, a first paddle on a first side of the nasal region and a second paddle on a second side of the nasal region. The first paddle is configured to contact one side of the nose of the user and the second paddle is configured to contact the other side of the nose of the user.

Patient interfaces

Frame for a mask assembly

A respiratory mask for providing positive pressure therapy having ball jointed elbow, one or more detachable forehead pieces and headgear comprising a spacer fabric region is disclosed herein. The elbow is configured to be removable when oriented to a predetermined position. The forehead pieces are provided in one or more sizes. The spacer fabric region comprises two or more layers wherein the raw edges are turned to the inside of the layers. The seal comprises features that improves seal performance and accommodates a wider variety of facial geometries.

Gender based full-face mask sizes

A respiratory mask includes a frame and a cushion module including a housing and a cushion that seals on a user's face in use. The housing includes a first connector, for example, a female connector, and the frame includes a second connector, for example, a male connector. The first and second connectors are coupled together in use. The housing includes one or more fasteners that secure the male connector to the female connector. Each fastener includes a base portion coupled to the housing and a moveable portion pivotally connected to the base portion. To assemble the mask, the male connector is inserted into the female connector such that the male connector engages the fasteners. Advancement of the male connector into the female connector causes the fasteners to change orientation from a neutral position to a toggled position and compress. The compressed fasteners apply a retention force to the male connector.

Respiratory mask system

Cushion assembly for breathing mask assembly

A patient interface includes a mask body, an elbow, a connector and a conduit. Any one or more of the mask body, the elbow, the connector and the conduit includes a bias flow vent. The bias flow vent is configured to deform with the application of pressure but not fully collapse such that an orifice size defined by the bias flow vent can vary with the application of pressure.

Pressure controlled exhaust vent

A respiratory mask system includes a headgear that, in use, secures the respiratory mask system to a patient's head. The headgear includes a pair of forehead straps that are coupled together by a forehead coupler to form a closed loop. The forehead coupler is removably connected to a frame of the respiratory mask such that the forehead straps remain in a closed loop. The pair of forehead straps can also be coupled together by positioning a male strap portion within an aperture of a female strap portion. The male strap portion has a free end that is configured to be received into the aperture. The male strap portion includes a plurality of notches that engage the aperture of the female strap portion and provide incremental adjustment. The free ends of the male and female strap portions have fasteners configured to engage the surface of the other strap portion.

Mask system headgear

Face mask frame for a respiratory interface

FIGS.-D &A-D disclose a large variety of methods of forming the headgear for use in combination with a breathing apparatus comprising a unitary plastic core within textile casings. In some configurations, the plastic core material penetrates or bursts-through the textile casing of the straps. Some configurations include over moulding, alignment posts, T-joints and joint housings with injection aperture. FIGS.-&A-C disclose a large variety of different headgear arrangements including top strap, front strap, rear strap and pairs of straps extending from the mask above and below the ear to meet behind the ear. FIGS.-B disclose a large variety of connectors connecting the headgear assembly to the mask assembly where the headgear, mask and connector form a closed loop the connector is disengaged with the mask assembly.

An interface for positive pressure respiratory therapy includes a mask assembly having a mask seal and a mask shell. The mask assembly is positioned lower than and exposes a bridge of the user's nose. The mask seal includes first and second portions on respective first and second sides of a nasal region that contact opposing sides of the user's nose. The first and second portions each include supports that help maintain a shape of the mask seal. A pair of covers can be supported relative to the mask assembly and adjacent a respective one of the first and second portions of the mask seal. The covers limit expansion of the first and second portions of the mask seal in response to pressurized air within the mask seal. The supports of the first and second portions can transfer load from the mask seal to the covers.
