Between pressure transducer and compensating-pressure transducer and the fixing self-control oversleeve cushion pad is set, in order to avoid sensor is given the uncomfortable sensation of patient in operation;
Acceleration transducer is a three dimension acceleration sensor, and quantity is more than or equal to 3, and locates in one plane;
Three dimension acceleration sensor is become by three unidirectional groups of acceleration sensors; The axial direction of three unidirectional acceleration transducers is vertical mutually;
Three dimension acceleration sensor is by two bidirectional acceleration sensors; Two bidirectional acceleration sensors a pair of axial direction wherein is parallel, and another is axially perpendicular to the axial plane that constitutes of another sensor.
Three dimension acceleration sensor is become with unidirectional groups of acceleration sensors by the bidirectional acceleration sensor; The axial direction of unidirectional acceleration transducer is perpendicular to two axial planes that constitute of described bidirectional acceleration sensor.
