BLOOD PRESSURE MEASUREMENT SYSTEM UTILIZING AUSCULTATORY SIGNAL ACQUISITION

The present invention provides a system for measurement of blood pressure by detecting the Korotkoff sound. The system comprises an arm band placed on the brachial artery of the user and pressure is applied to the artery by inflating the cuff through an inflation pump provided in a measurement unit, thereby forcing the artery to close. Further, the pressure is reduced by opening at least one valve and by reducing the pressure the Korotkoff sounds are detected using the ausculatory blood pressure monitoring component placed in pneumatic pathway of cuff. The acoustic sound is detected in the audible range of 20 Hz to 10 KHz and also ultrasonic range between 60 KHz to 80 Khz. In this range the signal to noise ratio is maximal. The method for detecting the blood pressure through the present system enhances acoustic signal detection that improves blood pressure measurement accuracy.
