Abstract
A novel device for automatically deflating a blood pressure cuff with a standard two way valve is disclosed. An adjustable deflation rate consistent with normally accepted medical practice of two or three millimeters per heartbeat may be maintained. A two state valve and associated control circuitry for maintaining a constant deflation rate are described. This allows accurate sensing of Korotkoff sounds at different pressure levels.
