Domestic also have entity and individual that arterial puncture needle is studied, and is 01216233.7 patent as application number, can not judge the whether patent of intravasation of trocar sheath but retrieve.
Summary of the invention
The present invention proposes a kind of novel medical blood vessel remaining needle, can judge whether trocar sheath enters artery and vein, improves the success rate of the rearmounted pipe of moving puncture; Draw point is worn out the probability to wall in when pipe is put in the reduction venipuncture.
The present invention realizes by following technical scheme:
A kind of novel medical blood vessel remaining needle, by interior wear the draw point entity, in wear the draw point syringe needle and the overcoat flexible pipe is formed, it is characterized by: design groove interior wearing on the draw point entity, in when wearing draw point syringe needle intravasation the inclined-plane downward, at overcoat flexible pipe start design breach, increase the anticoagulant coating on inside and outside wall of draw point and the overcoat hose inner wall interior wearing.
Wear the two-stage nitration of first three branch of draw point entity in the position of described groove is arranged on, shape can be many casements.
The start position of described overcoat flexible pipe is between described groove starting point and needle slope bottom.
Described remaining needle is worn the draw point entity design for hollow fully in described when intravenous injection, the chamfered portion of wearing the draw point syringe needle in when intra-arterial injection is designed to solid; Perhaps be designed to hollowly, plugged zone is set in inclined-plane bottom.
Beneficial effect of the present invention is: wear the inner blood backflow of draw point situation in can observing by groove, judge whether the overcoat flexible pipe enters artery and vein, improved the success rate of the rearmounted pipe that punctures greatly, wear draw point in the minimizing and penetrate the probability of opposite blood vessel, wear draw point in preventing to sound out repeatedly behind the inserting needle to be blocked by little blood clot.

The specific embodiment
First kind of embodiment of the present invention is: as Fig. 7, Fig. 8, Figure 12 and shown in Figure 13, in wear draw point syringe needle 8 chamfered portion be solid or hollow, in wear draw point entity 3 for hollow, at the interior two-stage nitration of wearing draw point 3 first three branch groove 5 is set and wears in the draw point in making and be interlinked to the outside, blood is worn when flowing through in the draw point from interior, just can observe blood by groove 5.When being used for intravenous injection because the blood back-flow velocity is slow and vein blood vessel is more tiny, in wear draw point syringe needle 8 and be designed to hollow its easier blood vessel that penetrates that makes; When being used for intra-arterial injection, the blood back-flow velocity is very fast and arteries is thicker, in wear draw point syringe needle 8 and be designed to solid, but it is too fast for preventing that blood from refluxing, cause judging whether overcoat flexible pipe 2 inserts blood vessel, or in wear draw point syringe needle 8 be designed to hollow, but in interior shutoff 11 of bottom design of wearing draw point syringe needle 8, with control blood back-flow velocity, judge clearly whether overcoat flexible pipe 2 inserts blood vessel.14 places are provided with breach 9 in overcoat flexible pipe starting point, and breach 9 can be different shape, and blood is worn draw point in can flowing into by breach, and groove starting point 13 can exceed overcoat flexible pipe starting point 14, helps rapider judgement overcoat flexible pipe starting point 14 and has entered tremulous pulse.As Fig. 9 and Figure 10, in wear draw point syringe needle 8 the inclined-plane downward when being made as intravasation, penetrate the probability of opposite blood vessel to wear draw point in reducing, improve and insert the success rate of trocar sheath, on the surface of puncture draw point outer wall 7, groove 5 with anticoagulant coating (as heparin coating) is set above the overcoat hose inner wall 6, when reducing repeatedly exploratory puncture, in wear the probability that draw point and overcoat flexible pipe are blocked by little blood clot easily, improve puncture success rate.
