BLOOD PRESSURE MEASUREMENT SYSTEM

摘要

A blood pressure measurement system includes a cuff, an automatic inflation-deflation device for supplying compressed air to the cuff, electronic circuits for discriminating Korotokov sounds, and display means for indicating both the maximum (systolic) and minimum (diastolic) values of blood pressure. The cuff is divided into two portions, namely a blood choking cuff portion and a sound collecting cuff portion. The variation of air pressure in the sound collecting cuff portion may be detected by a microphone sensor which is provided outside the cuff. The detected sounds are once separated into Korotokov sounds and heart sounds. Then both sounds are compared to confirm the simultaneous occurrence. These coincident sounds may be judged to be Korotokov sounds and used to measure blood pressure.
