Abstract

748,363. Respiratory appliances. BRITISH OXYGEN CO., Ltd. Aug. 4, 1954 [Aug. 5, 1953], No. 21626/53. Class 81(2). [Also in Group XXIX] A combined inspiratory and expiratory valve for use with a lung inflating apparatus of the bellows type comprises a movable member such as the diaphragm 11 separating an inlet 14 adapted to be connected to the bellows of the lung inflating apparatus from an outlet 15 adapted to be connected to a face mask or an endotracheal tube, and a non-return valve 19 mounted on the movable member, the arrangement being such that under the influence of a pressure wave delivered by the compressor the movable member moves to cut off the outlet 15 from vent apertures 18 before the valve 19 opens to permit fluid to pass to the outlet port 15 and that between the pressure pulsations the member 11 moves to open the connection between the outlet 15 and the vent apertures and simultaneously the valve 19 is closed to prevent return flow to the inlet 14. The outlet 15 is formed by a tube 16 the lower end of which forms a seating 17 spaced a short distance from the diaphragm 11 when the latter is in the normal unflexed position. The effective area of the vent may be varied by an adjustable obturator (not shown) or the vent may be provided with a spring-loaded valve the loading of which may be fixed or manually adjustable.
