Abstract

1364841 Mixing gases in proportions BRITISH OXYGEN CO Ltd 12 Aug 1971 [12 Aug 1970] 38865/70 Heading B1C [Also in Division A5] Apparatus for mixing two or more different fluids comprises an inlet line 1,3 for each of the fluids to be mixed, at least one on-off valve 30, 32, 34 controlling the flow of fluid through a set of conduits 6, 8, 10, 16, 18, 20, there being at least two sets of conduits with each set of conduits being connected to both or all of the inlets, and a calibrated flow control orifice 26 in each of the conduits, the conduits of each set being connected to a common outlet 21 downstream of the orifices. The apparatus may be used for producing an airoxygen mixture for a lung ventilator and in operation the oxygen line 1 and air line 3 are turned on and on-off valve 42 is turned off. A switch 28 through 36 is pressed to select a gas of the required composition. The flow mechanism of the lung ventilator turns on-off valve 42 on and off at the beginning and end of each inspiratory phase. The composition of the gas can be changed by pressing the appropriate switch 28 through 36, or a combination of switches. The calibrated flow control orifice 44 may be replaced by a demand valve, or a fine adjustment valve which allows a pre-set adjustable gas flow along outlet 21.
