PULSE CONDITION ACQUISITION APPARATUS AND METHOD

摘要

A pulse condition acquisition apparatus includes a base (1), a positioning component (2) and a sensor component (3). The sensor component (3) includes a motor (31) fixed on a housing, a lead screw (33) fixedly connected to the motor (31), a lifting structure (34) sheathed outside the lead screw (33), and a sensor probe (35) fixed on the bottom of the lifting structure (34). When the motor (31) rotates, the lead screw (33) is forced to rotate, and thereby the lifting structure (34) is forced to move up or down respect to the lead screw (33). A pulse condition acquisition method includes following steps: (a) forcing the lifting structure (34) to move up by the rotation of the motor (31), until the lifting structure (34) arriving at the initial position; (b) forcing the lifting structure (34) to move down for a determined distance by the rotation of the motor (31), and determining whether the lifting structure (34) arriving at the limit position: if YES, then stopping the detection, and if NO, then acquiring a pressure signal by the sensor probe (35); (c) repeating step (b), determining whether the current pressure signal acquired is larger than the previous one pressure signal acquired, and if NO, then stopping the detection.
