摘要：
A blood vessel pressing cuff includes a strap surrounding a body part, a first actuator disposed on the strap and including 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 including 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 that is different from the first temperature. If the first shape memory alloy changes to the first shape, pressure applied to the body part surrounded by the strap is increased. Even when the first shape memory alloy changes to the first shape, if the second shape memory alloy changes to the second shape, the pressure applied to the body part surrounded by the strap is reduced.
