The disposable use venoclysis needle of domestic each clinical use of clinical unit of medical institutions, mostly be to support the use with disposable infusion set, mainly by protective sleeve for bottle stopper puncture outfit, bottle plug puncture unit, air filter, infusion tube, dropper, dropping funnel, flow regulator, liquid medicine filter and venoclysis needle form, the venoclysis needle syringe needle is after using, because the venoclysis needle syringe needle does not have protector exposed outside, be easy to stab to medical personnel or personnel's accident of processing medical waste and cause secondary pollution, particularly as like hereby sick, hepatitis B, syringe needle after the patient of hepatitis C etc. uses; Now also have on the market the venoclysis needle of anti-acupuncture, but this series products all has certain defective, be " Disposable Butterfly's Needle Safe Needle Guard " just existence of 03102395.9 such as the patent No.: 1, operation is inconvenient, is difficult for observing blood back; 2, pin is difficult for fixing after the puncture, often becomes flexible to bring inconvenience to the nurse; The patent No. is that 02112106.0 " a kind of transfusion needle with safety device " also has problems: existing venoclysis needle automatic Composition is and needle handle assembly and needle stand bonding assembling molding direct through small hose, its safety device is small hose will be penetrated from the endoporus of safety device to run through, so just be difficult to engage with prior art, assembling can not suit to have now automatization's assembling, can not large-scale production, in addition since safety device at processing difficulty during the narrow line of rabbet joint, the wide needle tubing that then easily exposes of the line of rabbet joint; Other patent also all faces so several difficult problems.

The utility model content

The purpose of this utility model is to provide a kind of disposable use to prevent acupuncture double-vane venoclysis needle; can finish assembling on existing transfusion needle automatic Composition basis; can under the prerequisite that does not change the origin operation method, observe blood back again; can also after the medicinal liquid of being totally lost pulls out pin, can protect the transfusion needle syringe needle not expose, thus avoid patient with after the syringe needle accident stab and cause superinfection.

For achieving the above object, this utility model adopts following technical scheme: this utility model comprises needle shield, the venipuncture needle tubing, the double-vane needle handle, small hose, needle stand, needle stand cock and anti-acupuncture sheath, the venipuncture needle tubing, the double-vane needle handle, small hose, needle stand is linked in sequence by adhesive, needle shield is socketed on the double-vane needle handle, the needle stand cock is rotatably connected in the needle stand end, anti-acupuncture sheath cutting ferrule also can slidably reciprocate at small hose on small hose, it is characterized in that: anti-acupuncture sheath is divided into, close piece with two of draw-in groove down, on close on the piece respectively with hole clipping, locating hole, close down on the piece respectively with on close buckle corresponding to piece, positioning convex, on, close down piece by positioning convex and the trough rim jack-up of closing the piece front portion, middle hole clipping, buckle closely snaps into anti-acupuncture sheath, and makes the full of twists and turns double flute seam that has respectively formed vertically a correspondence on the anterior double side wall of preventing acupuncture sheath buckle.

Anti-acupuncture sheath of the present utility model upper or under close piece or the upper and lower piece that closes is provided with stop-return slot.

The lower piece that closes of anti-acupuncture sheath of the present utility model also can be buckle, positioning convex, on to close piece also can be with corresponding with it buckle, positioning convex.

The double flute of the axial complications of anti-acupuncture sheath of the present utility model is sewed on wall or lower wall and is provided with non-return step, raised points and corresponding depression with it, and the double flute seam also can be straight trough.

Be accompanied with a cap stopper on the sidewall that needle stand of the present utility model also can be present.

This utility model also can not worn the needle stand cock, directly and disposable infusion set or disposable use blood exchange transfusion set assemble use.

Because anti-acupuncture sheath is to be closed piece with two of draw-in groove and formed through engaging by upper and lower, it is upper and lower to close piece by positioning convex and closes the trough rim jack-up of piece front portion, and the resilient pressure that middle hole clipping, buckle engaging form makes that anti-acupuncture sheath is upper and lower to be closed in the piece card closely.

In addition; this utility model is in operating process; compare indistinction with the disposable use venoclysis needle of clinically conventional use; just after pulling out pin; need pinch on the other hand the position at the buckle rear portion of anti-acupuncture sheath; other hands small hose of pulling back at anti-acupuncture sheath rear portion is pulled back the double-vane needle handle to anti-acupuncture sheath, can avoid patient to stab other people with rear pin accident with blood and cause infection, thereby strengthen the protection to medical personnel's safety.
