BLOODLESS SPHYGMOMANOMETER AND BLOODLESS SPHYGMOMANOMETRY

摘要

PROBLEM TO BE SOLVED: To measure exact blood pressure values without imparting burdens to subjects by measuring the blood pressure values at the optimum cuff pressure reduction rates according to the cardiac rates of the respective subjects. SOLUTION: This bloodless sphygmomanometer has a cuff 10 for compressing the artery and a sphygmomanometeric means 20 for changing the cuff pressure by reducing the pressure of the cuff 10 under and at pressurization and a prescribed rate and detecting the artery phenomenon in the pressure reduction process of the cuff pressure and decides the prescribed blood pressure value from the data detected in the pressure reduction process of the cuff pressure. The instrument described above is constituted to have a memory 40 which detects the cardiac rate by the cuff pressure detecting section 22 of the sphygmomanometric means 20 and stores the detected cardiac rate data and a microprocessor 30 which calculates the optimum cuff pressure reduction rate in accordance with the cardiac rate data stored in the memory 40 and controls the cuff pressure reduction rate in the cuff pressure regulating section 21 of the sphygmomanometric means 20 by the optimum cuff pressure reduction rate.
