Abstract

1,133,164. Valves. O. H. DRAGER, [trading as DRAGERWERK, HEINR. & BERNH. DRAGER]. 16 Sept., 1966 [16 Sept., 1965], No. 41579/66. Heading F2V. [Also in Division A5] In breathing apparatus in which gas 2 is supplied under pressure through an inhalation duct 1, 1a, the duct is provided with a throttle 5 and a valve in parallel with each other and is arranged so that the main flow of gas into the outlet 1a through the valve is possible only after the pressure in the outlet 1a has been slowly raised by gas passing through the throttle. The valve comprises a seat 9 and a diaphragm 7 biased with a spring 8, the diaphragm moving away from the valve seat as the pressure rises in the outlet 1a. The breathing apparatus may include a breathing bag the outside of which is subjected alternately to positive and negative pressure to force the gas 2 through the duct and it is stated that the apparatus may be used for anaesthetizing a patient.
