  • Patent number: 8631799
    Abstract: A nasal cannula for supplying a respiratory gas to a patient and a method of treating a patient with sleep disorder. The nasal cannula comprises a pair of spaced apart supply lines which each have a head at one end thereof with a discharge opening located therein. The opposite end of each supply line is connectable to a high flow respiratory gas source. Each head is sized to be snugly received and retained within one of the nasal cavities of the patient while forming a sufficient leakage passage, between a portion of inwardly facing nasal cavity skin of a patient and a portion of an exterior surface of the head, to facilitate exhausting of any excess respiratory gas supplied to the patient through the leakage passage and also facilitate inhalation of any room air required in excess of the respiratory gas to be supplied to the patient.

  • Patent number: 8074652
    Abstract: A method of forming a cannula from a cannula mandrel assembly comprising a pair of mouthpiece/nasal mandrels and a mating facepiece mandrel. The facepiece mandrel has a pair of conical holes, in an intermediate section thereof, for receiving a leading end of one mouthpiece/nasal mandrel. The conical holes allow the facepiece mandrel to slide along the mouthpiece/nasal mandrels until the conical holes abut with respective mating tapering conical sections and prevent further sliding movement along the mouthpiece/nasal mandrels. Following assembly, the assembly is heated, at least one coating of a polymeric material is applied thereto and heat from the assembly at least partially cures the polymeric material on the assembly. Following curing, the facepiece mandrel and formed cannula are slide along the mouthpiece/nasal mandrels until the facepiece mandrel and formed cannula are removed therefrom. Lastly, the facepiece mandrel is removed from the formed cannula.

  • Patent number: 6786475
    Abstract: A bubble humidifier for adding humidity to supplied oxygen. The bubble humidifier has a humidifier base, for containing a quantity of liquid, and a cover for the humidifier base. The bubble humidifier has an oxygen inlet for supplying oxygen to the bubble humidifier and an moisturized oxygen outlet for connection to a moisturized oxygen supply conduit for supplying humidified oxygen to a patient, and the oxygen inlet being connected to a diffuser for diffusing the supplying oxygen within the bubble humidifier. The bubble humidifier has a pressure relief device for relieving excess pressure generated within the bubble humidifier during operation thereof. The bubble humidifier defining a longitudinal axis and the diffuser is arranged to discharge the oxygen from the diffuser substantially at an angle normal to the longitudinal axis of the bubble humidifier to minimize flow of liquid, contained within the humidifier base, from entering the moisturized oxygen outlet during operation of the bubble humidifier.
