PROBLEM TO BE SOLVED: To normally execute pressurizing by optimum pressure regardless of the present blood pressure of a patient. SOLUTION: An electrocardiogram electrode 9, etc., detects R-wave as a time interval detection reference point in the sphygmogram of an aorta in a living body and a pulse oximeter probe 12, etc., detects pulse wave at a peripheral blood vessel side, which appears after the pulse wave of the main artery. CPU 1 calculates a pulse wave propagating time from R-wave till pulse wave at the peripheric blood vessel side, calculates contraction period pressure based on the pulse wave propagating time and adds contraction period pressure to prescribed pressure so as to calculate the pressurizing pressure of a cuff 2. |
