A method of using a sphygmomanometer having a built-in arrhythmia detecting mechanism, wherein the blood pressure measuring portion contains a pulsation detector, which receives pulse sounds including Korotkoff sounds for electrically converting the pulse sounds into wave form signals of the vascular pulse wave and output the same, and a mechanism indicating the blood pressure value by means of detecting the Korotkoff sounds recognized and separated from the wave form signals of the vascular pulse wave output in the above-mentioned way; the incorporated arrhythmia detecting mechanism receives the wave form signals of the vascular pulse wave for comparing the cycle of the wave form signals with a predetermined criterion in order to electrically detect irregularities, if any, in the signals for detecting the existence of arrhythmias. This sphygmomanometer is capable of measuring the blood pressure simultaneously with the detecting of arrhythmia.

Method of arrhythmia detection with detecting mechanism

A cuff mechanism for use with a blood pressure measuring apparatus which comprises a flexible band, accommodating a cuff within the same wrappable (windable) in a cylindrical roll about an arm of a human body, and an air cylinder as a pulling means for pulling the band to tightly compress the band about the arm operated by pressurized air supplied in common with an air bag disposed in the band from an air supplying means. The flexible band is provided with, on occasion, a plurality of cross cuts formed on both sides thereof for better adaptation to the shape of an arm, and the air cylinder is sometimes pivoted to a stationary member swingably with a pin for being variable in the pulling direction of the band for better adaptation of the band to an arm of ununiform thickness and of irregular surface.
