Abstract
A device for automatically winding a blood pressure measuring cuff around a part of the human body. The cuff comprises a flexible band having a part fixedly secured to a surrounding member adapted to receive a part of the human body. The flexible band extends circumferentially along the inner wall of the surrounding member and having one end which is pulled circumferentially so as to be wound around a part of the human body. A flexible fluid chamber is provided along the inner wall of the flexible band to be interposed between the flexible band and a part of the human body. The flexible fluid chamber operates to apply a squeezing pressure to the part of the human body when a fluid is supplied to the flexible fluid chamber. A weight is connected to one end of the flexible band and a weight hoisting device is employed for hoisting the weight. A weight holder holds the weight at a predetermined hoisting position and a pulling force is caused by the weight when the holder is released and applied to the one end of the flexible band.
