HEAD BLOOD PRESSURE MEASURING EQUIPMENT

摘要

PURPOSE:To easily decide whether a cuff and a pulse wave detecting means are abutted on appropriate positions on an artery or not by increasing cuff pressure up to reference pressure and increasing the cuff pressure until the extinction of the amplitude of a pulse wave is detected when the amplitude of the pulse wave is reference amplitude or above. CONSTITUTION:A cuff pressure control means 4 drive-controls a pump 3, when cuff pressure P by a cuff 1 reaches reference pressure P0, the increase of the cuff pressure P is temporarily stopped, amplitude V of the pulse wave is compared with reference amplitude V0, and when the amplitude V is lower than the reference amplitude V0, the cuff pressure control means 4 inversely drive-controls the pump 3 and pressure-reduces the cuff pressure P, and a person to be inspected arbitrarily dislocates the positions of the cuff 1 and a pulse wave detecting means 2 and restarts the inspection. When the cuff 1 and the pulse wave detecting means 2 are abutted on the appropriate positions by trial-and-error in this manner, the amplitude V of the pulse wave becomes the reference amplitude V0 or above. At that time, it is informed to the person to be inspected that the pulse wave can be properly detected. The cuff pressure control means 4 further increases the cuff pressure P and stops the increase of the cuff pressure P when the extinction of the amplitude V of the pulse wave is detected, and blood pressure is measured from cuff pressure Pcs from which the amplitude V of the pulse wave is extinct.
