Abstract
1,129,194. Anaesthetic vaporisers. H. H. SAMSON. 13 March, 1967 [22 March, 1966], No. 11586/67. Heading AST. An anaesthetic vaporiser comprises an anaesthetic liquid container 10, an apertured chamber 44 (an acolipile) mounted for rotation and floatable on the liquid and connected to a source of pressurised gas, which gas, as it emerges through apertures 46, serves to rotate the chamber and vaporise the liquid, and an outlet 28, 32 (30, 38) for the vapour-gas mixture. A cock 22 in the pressurised gas inlet passage 24 is adjusted by a handle 52 to give a vapour-gas mixture concentration corresponding to the position of a pointer 54 on a scale 40. Pressurised gas enters the chamber 44 through a tube 20 on which a stem 42 of the chamber is telescopically arranged. A buoyant body 48 is mounted beneath the chamber 44 and maintains the apertures 46 a constant distance above the surface of the liquid. The apertures 46 direct gas jets downwardly and at an angle to the liquid so that the chamber and stem are rotated about the tube 20. Vapour gas mixture leaving the container through a conduit joins pressurised gas in a byepass conduit 36 and enters a tube 38 for supply to the patient.
