The specific embodiment
Below with reference to the accompanying drawings, the utility model is described in further detail:
As Fig. 1, shown in Fig. 2, a kind of safe vacuum blood taking needle that can automatic retracted, comprise the sheath 10 being connected with needle stand 8, fixing and be positioned at the puncture needle tubing 9 of sheath 10 with needle stand 8, needle stand 8 connects Connection Block 7, Connection Block 7 is bonded with flexible pipe 6, flexible pipe 6 is bonded with the sliding seat 4 that is positioned at containment 5, on sliding seat 4, be fixed with the blood-collecting needle tube 2 being connected with flexible pipe 6, blood-collecting needle tube 2 is covered with the protective cap 1 being connected with containment 5, it is characterized in that: on described containment 5, be provided with safety groove 5a, be positioned at the button 4b corresponding with draw-in groove is set on the sliding seat 4 of containment 5, the front end of sliding seat 4 is provided with spring 3,
