Abstract
628,727. Respiratory appliances. TALLEY, H. A. E. Oct. 10, 1947, No. 27259. [Class 81 (ii)] [Also in Group II] In apparatus for mixing gases, more par. ticularly in anaesthetic apparatus, a primary gas N 2 O, delivered through an adjustable flow valve 4 and flow gauge 3 to a jet 1 creates a suction in a surrounding venturi tube 2 which is transmitted via a control valve 6 to the control chamber of a diaphragm regulator 11 which determines the flow of a secondary gas, oxygen, between the conduit 14 and the venturi tube. The two gases are mixed as they issue from the jet and venturi tube and pass to the patient along the outlet 13. A conduit 12 is connected between the outlet tube 13 and a chamber on the side of the diaphragm opposite said control chamber of the regulator 11 so that the effect of pressure fluctuations caused by the patient may be cancelled by application thereof to both sides of the diaphragm. The valve 6 comprises a rotatable disc 8 having a plurality of graded nozzle openings 7 which may be selectively aligned with the outlet of conduit 10.
