Needle core is pierced into site of puncture by top, when needle core punctures and reaches paracentesis depth, keep needle core it is motionless, by drainage casing tube to
Lower slider is pierced into patient body at the position that needle core punctures, after drainage casing tube is pierced into patient body, by pulling casing by needle
Core pulls in drainage casing tube, makes pressing plate be extruded in middle hose section surface by rotary screw at this time, it is fixed in flexible tube section with
The relative position of drainage casing tube, and then position of the needle core in drainage casing tube is fixed.Conical shielding plate fits in patient's skin
The fixed relative position with wound in skin surface, blocks puncture, by gauze, absorbent cotton fill conical shielding plate and wound it
Between space, prevent bacterial virus from entering.The technical solution of the application in this way, which does not need to take out needle core, can reach puncture
The effect of drainage, it is therefore prevented that secondary pollution when puncture reduces the probability for causing infection.
