Blood pressure meter using viscoelasticity of cuff and mobile terminal having the same

A blood pressure meter comprising:

• a pressure adjusting member comprising a cuff that is elastically deformed at a time of fining 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 fining 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 through the lockers at the time of fining 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 slidably provided in the cuff fitting 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 fitting the cuff, and that is slid in the inversed direction over time, and
• wherein the cuff interference member further enhances the amount of decompression of the cuff.

• wherein the first and second pieces are locked to each other through 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 cuff is composed of a pair of bands, with one end of each of respective bands of the pair of bands fixed respectively to one end of the first and second pieces, and the other end of each of the respective bands free,
• wherein the pressure adjusting member further includes:
• a cuff hole formed in the hinge member so as to pass the free ends;
• and
• a cuff cam formed in the hinge member so as to compress the free ends when the first and second pieces are unlocked and release the free ends when the first and second pieces are locked, and
• wherein the cuff hole and the cuff cam further enhance the amount of decompression of the cuff.

• and
• a cuff driving unit that pulls the free end so as to compress the body part fitted with the cuff at the initial time of fitting the cuff, and releases the free end over so as to further enhance the amount of decompression of the cuff due to the viscoelasticity,
• wherein the cuff driving unit includes a cuff driving axis around which the free end of the cuff is wound, and
• wherein the cuff driving unit adjusts the compressing pressure and the decompressing pressure by rotating the cuff driving axis.
