  • Patent number: 10363381
    Abstract: Apparatus for warming medical infusion fluids includes a heat pipe (12) warmed by an electrical heater (17) at one end. A replaceable fluid flow path (20) of helical configuration extends along the heat pipe (12) and is formed between an inner, thermally-conductive sleeve (21) with a helical profile and an outer insulative sleeve (26). An inlet (3) to the flow path (20) is located adjacent the heater (17), the outlet (4) being at the opposite end of the heat pipe (12). The inlet (3) is connected to a suspended saline bag (1) and the outlet (4) connects via tubing (5) to a catheter (6) inserted in a blood vessel. A temperature sensor (18) in the outlet tubing (5) provides a feedback output to a control unit (11) that controls operation of the heater (17) to maintain a stable temperature.

  • Publication number: 20170319800
    Abstract: A respiratory therapy apparatus includes a rocker mechanism (101, 110, 111, 112) that provides an oscillating resistance to expiration. The apparatus also includes an air entrainment arrangement (200) at its air inlet (3) having a ring orifice (214) connected via a gas inlet (4) to a source (119) of oxygen at elevated pressure. The oxygen emerging around the ring orifice (214) entrains ambient air and supplies this as a continuous flow of respiratory gas to the patient interface (2) to provide a positive airway pressure.

  • Publication number: 20160022953
    Abstract: Heating elements for respiratory tubing (73) comprise an electrically-insulating substrate (22, 45, 50) with a printed looped track (21, 31, 41) of carbon extending along the substrate between two metal terminals (25, 26, 43, 44, 74, 75) at one end. The heating elements are preferably made by printing several looped tracks (51 to 59) side by side on an insulative substrate (50), applying a metal bus bar (60) along one edge (61) of the sheet over the free ends of the track loops. The bus bar is cut between the free ends of the tracks (51 and 59) to form isolated terminal pads connected with opposite ends of the tracks. The sheet is cut (63) between the tracks (51 to 59) to divide it into separate heating elements.

  • Patent number: 7302949
    Abstract: An improved humidifier which may be used with a nasal cannula for high-flow respiratory gas therapy wherein a sterilized liquid is drawn from a sterilized liquid container by a high-flow driving gas passing adjacent to an aspirator tube orifice through which the sterilized liquid is drawn into contact with the driving gas for fracturing the liquid into a mist which is warmed and delivered to the patient or user, and the driving gas is also passed adjacent a condensate return orifice which draws any condensate formed in the humidified respiratory gas delivery system away from the cannula and back into the system for re-use.
