Patent number: 10238826Abstract: This invention relates to a respiratory mask for delivering an inhalation fluid to the airways of a wearer. The respiratory mask includes a body of generally concave shape and having a peripheral edge, the body being adapted to provide a cavity in use about the mouth and nose of a wearer such that the inhalation fluid can be inhaled by the wearer from the cavity. The respiratory mask includes a resilient seal formation depending from at least a portion of the peripheral edge. The resilient seal formation includes both an inwardly and outwardly depending lip portion relative to the peripheral edge of the body. The mask may accommodate a range of facial dimensions whilst still retaining an effective seal.Type: GrantFiled: March 27, 2012Date of Patent: March 26, 2019Assignee: Intersurgical AGInventor: Richard Francis Bowsher

Patent number: 10166359Abstract: The invention concerns a connector for connecting respiratory ducts together such that they are placed in fluid communication. The connector comprises a first conduit having a female connector end and a second conduit having a male connector end adapted to be received within the female connector end of the first conduit such that the male and female connector ends form a common conduit having an inner surface formed at least in part by the male connector end. The male connector has a retaining formation which is adapted to abut a corresponding formation of the female connector so as to resist separation of the first and second conduits while permitting relative rotation there-between when connected. The inner surface of the male connector may comprise a gas washed surface in use. The engagement formation is preferably a recessed area of the female connector, which may be generally annular in shape. In one embodiment, the member(s) may comprise a valve seat.Type: GrantFiled: March 8, 2013Date of Patent: January 1, 2019Assignee: Intersurgical AGInventor: Laura Elizabeth Breckon
