Abstract
The invention relates to an intravenous puncture needle. The intravenous puncture needle comprises a protection casing pipe, a syringe needle, syringe needle fixing bases, a spring, needle wings, a switch clip, a Y-shaped pipe, a sealing rubber cap and protection cover, a heparin cap and a needle handle. The syringe needle fixing bases are sleeved with the protection casing pipe, and the spring jacks up the syringe needle fixing bases, so that the syringe needle fixing bases and the protection casing pipe are clamped through clamp teeth; after the intravenous puncture needle is used, the syringe needle fixing bases are downwards pressed, the syringe needle retracts into the protection casing pipe, and patients are effectively prevented from being punctured by the point of the needle. As one end of the Y-shaped pipe is connected with the heparin cap, the needle can be used for transfusion, and as the other end of the Y-shaped pipe is provided with the sealing rubber cap and protection cover, the needle can also be used by being connected with a postoperative analgesia pump. The intravenous puncture needle is simple in structure and convenient to use, intravenous puncture frequency is low, pains of the patients are relieved, and workloads of nurses are saved.
Description
Technical field
The invention belongs to technical field of medical instruments, relate in particular to a kind of venipuncture needle.
Background technology
At present, disposable venipuncture needle is indispensable medical apparatus and instruments in venous transfusion, blood sampling, therapeutic process, and mostly the venipuncture needle using clinically is at present, in venipuncture needle surface, one plastic tube is set, contaminated to prevent needle body, when use.Must first plastic bushing be removed; carry out again venipuncture; owing to there is no special storing unit; when infusion-completed; plastic tube disappears without a trace and the needle point after using can not be protected often; find in time plastic bushing, owing to being sleeved on again on needle body, just had the danger of being stabbed by needle point.
Summary of the invention
The present invention has and is stabbed dangerous problem by needle point a kind of simple in structure, easy to install, venipuncture needle of increasing work efficiency is provided for solving existing disposable venipuncture needle after use.
The technical scheme that the present invention takes for the technical problem existing in solution known technology is:
The venipuncture needle of the embodiment of the present invention, this venipuncture needle comprises: protective casing, syringe needle, syringe needle holder, spring, the pin wing;
Syringe needle and syringe needle holder are installed together, and tubulose syringe needle fixed seating is contained in protective casing, between protective casing and syringe needle holder, are provided with spring, and the pin wing is arranged on the end of syringe needle holder.
The present invention can also adopt following technical measures:
In an embodiment of the present invention, be provided with sliding tray on protective casing, the bottom of protective casing is provided with taper serration latch.
Further, on syringe needle holder outer surface, be provided with the slider bar matching with the sliding tray on protective casing, the end of slider bar is the wedge structure matching with latch.
Further, this venipuncture needle also comprises: switch card, Y tube, sealing foot cap and protective cover, calparine cap, needle handle;
On syringe needle, be provided with protective casing, there is fluid sealant protective casing and needle handle junction, and protective casing upwards extends to be connected with Y tube in extension tube switch card, and one end of Y tube connects calparine cap, and the other end of Y tube is provided with sealed gum cap and protective cover.
Further, adopt the calparine cap of transfusion use.
Further, the Y tube that adopts Postoperative Analgesia After pump to use.
Advantage and good effect that the present invention has are: because the present invention is contained in syringe needle fixed seating in protective casing; spring is by syringe needle holder jack-up; make syringe needle holder and protective casing by latch engagement; after finishing using; press indentor point holder downwards; syringe needle shrinks back protective casing, effectively avoids being stabbed by needle point.Y tube of the present invention one end connects calparine cap, the use of also can infusing, and one end is provided with sealed gum cap and protective cover, can connect Postoperative Analgesia After pump and use.Of the present invention simple in structure, easy to use, less venipuncture number of times, alleviates patient's misery, saves nurse's workload.
