Abstract
A digital readout electronic blood pressure and pulse rate monitor. A finger cuff occluder is pressurized by a single stroke plunger and an automatic vent means provides linear pressure decay while a pressure transducer measures the pressure and converts it to an electronic signal. A sound transducer senses sound transmitted from the cuff through the pressure tube, and an electronic system distinguishes the various characteristics of the sound to measure the systolic and diastolic pressures. The electronic system also measures the pulse rate. All three readings are digitally displayed only if several predetermined conditions indicating a proper reading are fulfilled.
