ABSTRACT:
A valve assembly for a sphygmomanometer controls the inflation and deflation of a pressure cuff. The valve assembly includes an inlet connectable to a fluid pressure source such as a bellows, an outlet which is connectable to a blood pressure cuff, an inlet directional control which actively prevents the flow of fluid from the outlet to the inlet, axial passages which connect the inlet to the outlet, and means for slowly and fixedly or rapidly releasing pressure. The valve assembly may be set to one of three positively located positions: a cuff inflation position, a metered deflation position, or a fast vent position. In the cuff inflation position, fluid pressure delivered to the valve assembly's inlet passes through an inlet directional control to the valve assembly's outlet and on to the pressure cuff which becomes inflated. In the metered deflation position, fluid flow returned from the pressure cuff through the outlet is metered out of the valve assembly in order to slowly deflate the pressure cuff at a consistent rate, regardless of the number of different readings or operators. In the fast vent position, fluid flow returned from the pressure cuff through the outlet is directed through large exhaust openings so that the pressure cuff can be rapidly deflated.
