Abstract
Abstract A cuff for a sphygmomanometer is constituted of an air bag for pressurization into which a predetermined amount of air is supplied and connected to a pressure sensor, an air bag for press into which a predetermined amount of fluid is supplied for causing the pressurization air bag to press the artery in the wrist portion, and a band for attaching both air bags to the wrist portion. When blood pressure is to be measured, a predetermined amount of air is supplied into the pressurization air bag and then air is supplied into the press air bag. The press air bag is accordingly expanded to cause the pressurization air bag to pressurize the artery. In this way, the sphygmomanometer cuff is provided which can overcome discomfort due to a feeling of being overly pressurized or dampness and ensure blocking of the blood flow in the artery so as to achieve measurement with higher precision.
