Patent ID: 8652058

Claim:
A blood vessel pressing cuff comprising: a strap adapted to surround a body part; a first actuator disposed on the strap, and comprising a first shape memory alloy which changes to a first shape memorized in advance, at a temperature equal to or higher than a first temperature; and a second actuator disposed on the strap and separated from the first actuator along a length of the strap, and comprising a second shape memory alloy which changes to a second shape memorized in advance, at a temperature equal to or higher than a second temperature which is different from the first temperature, wherein the first actuator is adapted to apply an increased pressure at a target part of the body part when the first shape memory alloy changes to the first shape, and wherein the first actuator is adapted to apply a decreased pressure to the target part of the body part due to the change of the second shape memory alloy to the second shape.
