Side be equipped with anti-viscose paper, the other end of needle stalk is equipped with connecting tube, and one end of connecting tube is equipped with connecting pipe box, institute
That states connecting pipe box is internally provided with connecting pipe box internal thread, and the bottle stopper includes chock plug, hand-held lid and infusion column, and hand-held
Lid is provided with chock plug external screw thread, and chock plug external screw thread and spiral shell in connecting pipe box between chock plug and infusion column on the chock plug
Line screws connection.
Further, the needle stalk is fixedly connected with puncture needle by rubber sleeve.
Further, the diameter of the connecting pipe box is more than the diameter of chock plug.
Further, the externally threaded length of the chock plug is less than the length of connecting pipe box internal thread.
Further, the connecting pipe box and bottle stopper are a kind of component of polypropylene material.
Compared with prior art, the advantageous effect that the utility model is reached is：The utility model is designed reasonably, structure are tight
It gathers, by the anti-viscose paper being arranged on needle stalk and needle handle and anti-dynamic adhesive tape, can be fixed convenient for blood taking needle, without another
Outer adhesive tape of taking is fixed, and then easy to use, simple, is satisfied the use demand, and is saved the time, and the connecting pipe box for passing through setting
Internal thread and chock plug external screw thread can make the connecting tube of blood taking needle connect the leakproofness for preferably ensureing its connection with bottle stopper, to
Be conducive to take a blood sample, and then use reliably, while manufacture craft is simple, cost is less, convenient for promoting the use of.
