Abstract:
1. A blood pressure meter comprising: a pressure adjusting member comprising a cuff that is elastically deformed at a time of fitting the cuff onto a body part of a testee to compress the body part and impede blood flow, and whose compressing pressure to the body part is decreased over time due to its viscoelasticity; a blood pressure sensor that measures the pressure of the body part at a time of compression and decompression of the pressure adjusting member; and a control unit that analyzes a signal measured by the blood pressure sensor at the time of compression and decompression of the pressure adjusting member and calculates the blood pressure of the testee, wherein the pressure adjusting member further includes a cuff fitting member having first and second pieces with lockers provided at one end of each piece, and of which the other ends are coupled to each other with a hinge member, wherein the first and second pieces are locked to each other though the lockers at the time of fitting the cuff, and the first and second pieces are unlocked and opened about the hinge member at the time of removing the cuff, wherein the pressure adjusting member further includes a cuff interference member that is rotatably provided in the cuff fining member, that contacts and interferes with the cuff in a direction in which it is adapted to come in close contact with the body part at the initial time of fining the cuff, and that is rotated in the inversed direction over time, and wherein the cuff interference member further enhances the amount of decompression of the cuff.
