Abstract

967,421. Respiratory apparatus. SVENSKA A.B. GASACCUMULATOR. Nov. 5, 1962 [Nov. 17, 1961], No. 41706/62. Heading A5T. Breathing apparatus for anaesthesia or artificial respiration comprises a breathing-bag 6 connected to an inhalation pipe 5 and through a non-return valve 7 to a supply tube 3 which has a relief valve 8. The non-return valve and the relief valve are biased to closed position by a common spring 11, opening of the non- return valve increasing the bias on the relief valve. For closed circuit operation an exhalation pipe 2 is connected to the supply tube, a carbon dioxide filter 4 being provided. A bored valve piston 13 may be disposed at III between the exhalation pipe and the supply pipe. In one position the piston permits communication between the exhalation pipe and the supply tube for closed circuit operation and in another position the piston connects the exhalation pipe with atmosphere for open circuit operation. Artificial respiration or arresting of respiration is effected by applying appropriate pressures on the breathing-bag.
