Patent ID: 7070567

Claim:
An inflatable cuff for blood pressure measurement, comprising: a first inflatable bag which is inflatable to press an arterial vessel of a body portion of a living subject and stop flow of blood in the arterial vessel which the inflatable cuff is adapted to be wound around the body portion; a second inflatable bag for sensing a pulse wave propagating along the arterial vessel, the second inflatable bag is supported by the inflatable cuff such that the second inflatable bag is located inside a downstream-side portion of the first inflatable bag as seen in the direction in which the blood flows in the arterial vessel, and which has a dimension as measured in said direction that is smaller than a dimension of the first inflatable bag as measured in said direction; a shielding member disposed between the first inflatable bag and the second inflatable bag so as to prevent an oscillation of the first inflatable bag from propagating to the second inflatable bag, and a slidable separating member disposed between the shielding member and the second inflatable bag for preventing a slide contact of the shielding member with the second inflatable bag.
