Abstract

750,152. Respiratory appliances. BLEASE, J. H. March 10, 1954 [March 10, 1953; July 28, 1953], Nos. 6616/53 and 20951/53. Class 81(2). [Also in Group XXIX] A valve device for use when supplying air or gas to a face mask allows air to flow freely to the mask on the application of pressure but, on the cessation of pressure, permits unimpeded exhalation to atmosphere. A flexible diaphragm 6 carries a light flap valve 13 at its centre and, when flexed, engages a resilient annular stop 16 at one side or a rim 8 at the other. When air is supplied under pressure through tube 2, the diaphragm 6 moves to the right against the rim 8, to seal the gap, and valve 13 opens to allow air to pass to the patient through tube 1. On the cessation of pressure the natural resilience of the diaphragm 6 and flap 13 returns the diaphragm to its central position and closes the valve, while, at the same time, a free passage is opened to atmosphere around rim 8 and through apertures 9, 9. In a modified form of the central valve the diaphragm carries a perforated cylinder, the left-hand end of which carries a disc valve, normally closed by a spring accommodated within the cylinder.
