Patent ID: 7144374

Claim:
A cuff for a blood pressure monitor fitted to a measurement site of a living body for measurement of a blood pressure value, comprising: a cuff main unit wound around the measurement site to be fitted on the living body, wherein said cuff main unit includes: a fluid bag for pressing the living body, an elastic member wound annularly on the outside of said fluid bag and changeable in size in a radial direction, and a diameter increasing/decreasing mechanism for increasing/decreasing a diameter of said elastic member wherein said diameter increasing/decreasing mechanism includes a diameter-decreased state maintaining mechanism for maintaining said elastic member in a diameter-decreased state by restricting elastic deformation of said elastic member in a radially outward direction, a diameter-decreased state releasing mechanism for releasing said elastic member to a diameter-increased state by releasing the restriction of the elastic deformation of said elastic member by said diameter-decreased state maintaining mechanism, and a diameter-forcibly-decreasing mechanism for forcibly decreasing the diameter of said elastic member in opposition to an elastic force of said elastic member in the diameter-increased state, and each of said diameter-decreased state maintaining mechanism, said diameter-decreased state releasing mechanism and said diameter-forcibly-decreasing mechanism works in association with manipulation of a manipulation portion; a handle provided on an outer peripheral surface of said cuff main unit and gripped with a hand for fitting of the cuff; and wherein said manipulation portion is provided at said handle or at said cuff main unit in the vicinity of said handle, wherein said manipulation portion increases/decreases the diameter of said elastic member by switching an operation of said diameter increasing/decreasing mechanism.
