Detailed description of the invention

By the examples below 1, in conjunction with accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4, technical scheme is further elaborated with.

Embodiment 1: the present embodiment is in FIG, utilize the pressure sensitive signal (6) of the contact position puncturing needle tubing (1) needle contact position, pass to the normal saline in the flexible pipe (2) filling normal saline, then the pressure sensitive signal (7) that normal saline conducts is passed to pressure sensitive device (3), pressure sensitive device (3) is by after pressure data, pressure on the number signal (8) is passed to displaying alarm (4), and displaying alarm (4) exports (5) power supply to pressure sensitive device (3) by DC source simultaneously. In conjunction with Fig. 2, further illustrate structure and the principle of pressure sensitive device in the technical program, in fig. 2, the flexible pipe one end filling normal saline is enclosed within connecting pipe (201), turn clockwise fastening hose nut (202), fixes flexible pipe, opens valve (203), the normal saline with pressure is made to enter pressure transducer (204) induction zone, pull-up venting rubber stopper (206), the Rubber end of its bottommost lifts gap, discharges gas from air vent (207), draw 3 times, it is ensured that aerofluxus completes.
