The invention discloses a kind of visible blood-back blood taking needle, its venipuncture needle and the two ends that pipe close puncture needle is same needle tubing, there is different needle point types at these two ends, and the needle point by venipuncture end needle stand is suitable for venipuncture, and the needle point of tube plug cutting tip needle stand is suitable for pipe close and punctures.This product overall structure is simple, easy to assembly, easily realizes full-automatic assembling and mass produces.During use easy and simple to handle, it is not necessary to other additional steps, working effect is stable, has good practicality, the great market competitiveness.
Accompanying drawing explanation
Fig. 1 is present configuration schematic diagram.
Detailed description of the invention
With reference to the accompanying drawings, the present invention is further described below.
nullThe present invention is a kind of visible blood-back blood taking needle，As shown in FIG.，It mainly includes venipuncture end needle stand 7，End, venipuncture end needle stand 7 one end is fixing with pipe close cutting tip needle stand 11 one end to be connected，Both become an overall structure by welding (bonding)，Between the two be internally formed certain sealing space，I.e. blood back observes storehouse 8，Needle tubing 4 runs through venipuncture end needle stand 7 and the centre bit inner chamber of pipe close cutting tip needle stand 11，Needle tubing 4 is located to form needle tubing venipuncture end 1 outside venipuncture end needle stand 7，Needle tubing 4 forms needle tubing pipe close cutting tip 6 outside pipe close cutting tip needle stand 11，It is characterized in that: described venipuncture end needle stand 7 inner chamber is hollow form，Its lumen centers position forms blood back isolation outer tube 2，Blood back isolation outer tube 2 one end is integrative-structure with venipuncture end needle stand 7 inwall，Blood back isolation outer tube 2 other end is unsettled，Blood back isolation outer tube 2 inner chamber forms blood back and observes storehouse 8，Needle tubing 4 is positioned at the one of blood back observation storehouse 8 and is provided with at least one blood back mouth 9 at tube wall，Described blood back mouth 9 is transverse groove or aperture，Blood back isolation inner tube 10 it is provided with at the free end of blood back isolation outer tube 2，One end of blood back isolation inner tube 10 and pipe close cutting tip needle stand 11 are in integrative-structure，And it is positioned at pipe close cutting tip needle stand 11 centre bit，The other end of blood back isolation inner tube 10 is the most unsettled，And and blood back isolation outer tube 2 free end between formed gap 3.The cavity volume and the cavity volume sum of pipe close cutting tip gum cover that are formed between described blood back isolation inner tube and blood back isolation outer tube form a cumulative volume, and this cumulative volume is needle tubing venipuncture end end to 18 ~ 25 times of the syringe intracavity volume between blood back mouth.
In the specific implementation, it is socketed with pipe close cutting tip gum cover 5 outside described needle tubing pipe close cutting tip 6.
In the specific implementation, the end of the free end of described blood back isolation inner tube 10 is positioned at the end of blood back isolation outer tube 2 free end.
In the specific implementation: the venipuncture end needle stand 7 become by transparent or semitransparent plastic injection welds (bonding) with pipe close cutting tip needle stand 11 becomes an overall structure, define therein and necessarily seal space, i.e. blood back observes storehouse 8, blood back on pipe close cutting tip needle stand 11 is isolated in the blood back isolation outer tube 2 that inner tube 10 is deep on venipuncture needle stand 7, gap 3 is defined between two isolated tubes, gap 3 can be easy to blood and flows through, needle tubing 4 through venipuncture end needle stand and pipe close cutting tip needle stand has blood back mouth 9 in blood back observes storehouse 8, blood back mouth 9 is transverse groove or aperture, the needle tubing venipuncture end 1 of needle tubing 4 is positioned on venipuncture end needle stand 7, the needle tubing pipe close cutting tip 6 of needle tubing 4 is positioned on pipe close cutting tip needle stand 11.After visible blood-back blood taking needle punctures vein, blood i.e. along venipuncture needle end 1, enters gap 3 by blood back mouth 9 and blood back observes storehouse 8, and observing storehouse 8 through blood back can be with visible directly blood back situation, judge that whether accurate venipuncture is, it is smoothed out blood sampling, after seeing blood back, the needle tubing pipe close cutting tip 6 of needle tubing 4 is thrust vacuum test tube, pipe close cutting tip gum cover 5 is pierced, blood channel connects with vacuum test tube, and blood can flow into vacuum test tube by automatic ration, smoothly completes blood specimen collection.
After having taken a blood sample, be retained in blood back and observe the blood in storehouse and cannot clean, also cannot sucking-off, just can identify by eyesight and use, can play and avoid reusable effect.
Above content is to combine concrete preferred embodiment further description made for the present invention, it is impossible to assert that the present invention is embodied as being confined to these explanations above-mentioned.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, it is also possible to make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
