Patent ID: 8579826

Claim:
An arteriosclerosis degree judgment device comprising: a first fluid bag to be wrapped around a measurement site at a central side thereof and a second fluid bag to be wrapped around the measurement site at a peripheral side thereof; a compression member located at outer circumferential sides of both of said first fluid bag and said second fluid bag to oppose to said measurement site, for integrally covering both of said first fluid bag and said second fluid bag; a first sensor for measuring an internal pressure in said first fluid bag; an adjustment unit for adjusting a pressure force of said compression member; a detection unit for detecting a pulse wave at said measurement site based on a change in the internal pressure in said first fluid bag; and a calculation unit for analyzing said pulse wave to calculate an index for judging a degree of arteriosclerosis, wherein said adjustment unit causes said compression member to pressurize both of said first fluid bag and said second fluid bag so as to be compressed against said measurement site, said first fluid bag and said second fluid bag being pressed against said measurement site with a certain pressure force, and wherein said detection unit detects the pulse wave at said measurement site based on the change in the internal pressure in said first fluid bag while being pressed against said measurement site with said certain pressure force, wherein said compression member is a third fluid bag, and wherein said adjustment unit detects vibration in said third fluid bag and actively exerts control for adjusting an internal pressure in said third fluid bag in accordance with the vibration of said third fluid bag serving as said compression member to actively cancel out said vibration.
