Abstract
A CPAP system for supplying humidified gases to a user. Various interfaces are described for delivering the gases. A mask cushion including a deformable cushion and thin sheath is described. A forehead rest with a horizontal pivot is attached to the mask. An outlet vent to reduce the noise from exhausted carbon dioxide is described. A mouthpiece is also described with an outlet diffuser including Heat Moisture Exchanger Material.
Claims30
A device for delivering a supply of gases to a user from a breathing assistance apparatus comprising:
- a patient interface engaging with said user and thereby supplying said gases to said user.
- a connector adapted to fluidically communicate said patient interface with said breathing assisting apparatus, including a plurality of outlet vents formed in a flexible portion thereof, said outlet vents adapted to pass a substantial portion of the expired gases of said user.
A device for delivering a supply of gases to a user comprising:
- a mask;
- having a frame and a substantial seal to the face of said user, adapted to be in fluid communication with said supply of gases,
- first engagement means adapted to engage said nasal mask to the head of a user, and
- second engagement means adapted to pivotally engage said frame to the head of a user, said second engagement means having at least one configuration, a first configuration such that in use said engagement means may freely pivot with respect to said frame.
A device for delivering a supply of gases to a user comprising:
- a hollow body including a gases inlet and gases delivery aperture, said gases inlet in use in fluid communication with said supply of gases,
- resilient sealing means adapted to engage around or adjacent to the periphery of said gases delivery aperture, and
- flexible sealing means adapted to engage around or adjacent to the periphery of said gases delivery aperture between said resilient sealing means and a user, and significantly higher in density than said resilient sealing means,
- wherein said resilient sealing means and said flexible sealing means including at least a portion shaped to approximate the facial contour of a user.
A mouthpiece for delivering a supply of gases to a user from a breathing assistance apparatus comprising:
- engagement means adapted to in use juxtapose said mouthpiece in or about the oral cavity of a user and substantially seal thereabouts,
- a conduit adapted to fluidically communicate a breathing assistance apparatus with the oral cavity of a user, and
- diffusing means adapted to be in fluid communication with said conduit and located substantially within, and delivering said supply of gases in a substantially diffused manner to, the oral cavity of a user.
