Abstract
1286840 Respiratory appliances DYNASCIENCES CORP 22 Nov 1969 57265/69 Heading A5T A valve for respiratory apparatus as described in Specification 1286839 is provided with manually operable balance over-riding means which may be actuated to lift the valve member (90), Fig. 1 (not shown) initially from its seat when the patient is incapable of initiating operation of the valve himself. The overriding means may be provided by mounting the upper magnet 98 on a spring loaded plunger 106, which, when depressed by means of a push button 108 lowers the magnet to lift the valve member 90 up. Alternatively, the outlet (82) from the valve housing (12) to the atmosphere may be provided with a valve (116), Fig. 3 (not shown), which, when closed by a push button 108, prevents air leaking from the high pressure oxygen inlet from escaping to the atmosphere, so that the pressure builds up in the housing (12) and lifts the valve member (90) from its seat.
