<p>PROBLEM TO BE SOLVED: To keep air capacity in an ischemic bag at using time almost constant, and improve measuring accuracy by providing an expansion restricting means which can expand a winding remaining part of a cuff remaining without being wound round a measuring object region by air and restricts its expansion to a fixed quantity. SOLUTION: A cuff housing part 6a constitutes an expansion restricting means 6 which can expand a winding remaining part 4b of a cuff 4 and restricts its expansion to a fixed quantity. The cuff housing part 6a is formed in a box shape having an inside plate 14 formed in a curved shape according to an outer peripheral shape of a measuring object region 1 and an outside plate 15 formed in a curved shape at the same bending rate as it, and a cavity 6b capable of housing the winding remaining part 4b of the cuff 4 so as to be freely taken in and out, is formed inside of it. The cavity 6b has a uniform thickness (d) over the total length, and is set so that an expansion quantity of a part 4a wound round the measuring object region 1 of the cuff 4 and an expansion quantity of the winding remaining part 4b become almost the same value.</p> |
