Abstract
A kind of Anti-stabbing venipuncture needle solves contaminated pinhead in medical domain and stabs human body and cause infecting the problem of infectious disease.Shown in accompanying drawing 4, this puncture needle needle handle heel that tradition punctured has added a breach, addition of an anti-stab sleeve that is transparent, that can be axle center pushed forward with pin bone cylinder outside puncture needle pin bone cylinder.As long as after pulling out pin, by anti-stab sleeve cylinder handle 2 pushed forward, to puncture, needle handle 13 blocked by direct neck 7; puncture needle piercing portion is covered by anti-stab sleeve is stable, extremely short (only needing a second) consuming time simple operations can just reach protection human body not by effect that needle tip piercing portion is stabbed.Infusion needle, blood transfusion syringe needle, blood collection needles can be widely used in, avoid medical domain human body to be stabbed infection infectious disease by this kind of contaminated pinhead.
Description
Technical field
This utility model solve specially in medical domain pollute posterior vein transfusion, blood transfusion, blood collection needles stab human body and cause infecting the problem of infectious disease.
Background technology
Within every 30 seconds, there is a contaminated syringe needle of nursery work person to stab according to the scientific statistics whole world, have at least nearly 1,000,000 syringe needles event of stabbing to occur every year.China is hepatitis B country occurred frequently, always infection rate is up to about 61%, and hepatitis C is also in rising trend, and acquired immune deficiency syndrome (AIDS) is also increasing year by year.Given this my specialized designs produce " Anti-stabbing venipuncture needle " and solve in clinical medicine because pricking wound infects the problem of above-mentioned infectious disease.
Stab human body according to clinical investigation statistics vein puncture needle head and mainly occur in following link:
1, syringe needle is after extracting patient body, circularizes packing character because syringe needle hose segment curves, and elastic potential energy is converted into the kinetic energy of syringe needle by operator at the resilience of placement moment syringe needle Memorability, small hose
allow the hard to guard against hand of being wounded by stabbing of people, this injury to there is no operating experience or do not have the intern of sense of self-protection and new Nurses particularly general.
2, the syringe needle that is exposed when operator is with pin to return in way or syringe needle is included into sharp disposable container operation is stabbed.
3, part nursery work person in order to avoid above two kinds stabbed probability blindly operation, stabbed when being again inserted in pin cap with the contaminated pinhead crossed.
4, due to the large fatigue of workload or concentrate on clinical treatment rescue work, be very easily negligent of self-protection and be wounded by stabbing.
Summary of the invention
The purpose of this utility model is: by a transparent anti-stab sleeve additional outside venipuncture needle pin bone cylinder, as required can neatly with pin bone cylinder for axle center driven forward, reach puncture needle piercing portion all stable effects sealed.The contaminated syringe needle of human body is avoided to stab infectious diseases such as infecting hepatitis B, hepatitis C, acquired immune deficiency syndrome (AIDS), syphilis completely.
The purpose of this utility model is achieved in that a kind of Anti-stabbing venipuncture needle (Fig. 2) is made up of venipuncture needle and anti-stab sleeve (Fig. 1).It is characterized in that the many breach 12 of described puncture needle needle handle 13 root and front end, pin bone cylinder junction.Anti-stab sleeve 1 is the hollow cylinder the same with pin cap 8 internal diameter, anti-stab sleeve has straight trough mouth 5, skew notch 6, direct neck 7 three notches, connecting before and after three notches can be movable in notch as required for puncture needle handle 13, anti-stab sleeve 1 front end be provided with sleeve cylinder handle 2 convenient by its with pin bone cylinder 14 for axle center pushed forward.It is the same with traditional operation that this structural design makes Anti-stabbing venipuncture needle operate before pulling out pin.What be better than traditional puncture needle is after pulling out pin, and all can be inserted in needle tubing sleeve 1 by syringe needle 10, needle tubing 11, round platform funnel 9 and part pin bone cylinder 14, syringe needle 10 is sealed.The combination of skew notch 6, direct neck 7 can make needle handle 13 be sticked into direct neck 7, and fixing anti-stab sleeve can not slide anteroposterior, thus makes puncture needle piercing portion complete stability be sealed by anti-stab sleeve, can not stab human body.
The present invention has the following advantages: be 1. easy to operation consuming time extremely short; 2. simple structure, with low cost, environmental protection; 3. be widely used, can be mass-produced and be applied to infusion needle, blood transfusion syringe needle, blood collection needles; 4. safe and reliable, practical, completely avoid the contaminated syringe needle of human body and stab and infect the probability of the infectious diseases such as hepatitis B, hepatitis C, acquired immune deficiency syndrome (AIDS), syphilis.

Fig. 3 has pulled out pin cap figure before puncture procedure
Fig. 4 is the anti-stab design sketch that after puncture procedure, anti-stab jacket casing lives syringe needle
Specific implementation method
Below in conjunction with accompanying drawing, this utility model is further described.
Anti-stab sleeve shown in accompanying drawing 1 is made up of needle tubing sleeve 1, sleeve needle handle 2, straight trough mouth 5, skew notch 6, direct neck 7 is opened in the middle of needle tubing sleeve 1, connect before and after straight trough mouth 5, skew notch 6, direct neck 7 three notches, straight trough mouth 5 and skew notch 6 are 60 degree of overturning angles, direct neck 7 is parallel with straight trough mouth 5, the not opening place of leading portion of needle tubing sleeve 1 is front card cylinder 3, the not opening place of back segment of needle tubing sleeve 1 is rear card cylinder 4, needle tubing sleeve 1 and pin cap 8 same material make, and rear end direct neck 7 and rear card cylinder 4 also can select slightly soft material as required.
Shown in accompanying drawing 2, needle tubing sleeve 1 internal diameter is identical with pin cap 8 internal diameter, front card cylinder 3 can be fixed anti-stab sleeve and not slide to flexible pipe 15 direction, rear card cylinder 4 fixes anti-stab sleeve not to syringe needle 10 direction landing (Fig. 4), needle tubing barrel forward end firmly installs one and puncture needle handle 13 size shape identical sleeve cylinder handle 2, and puncture needle handle 13 opens a breach 12.
This utility model implements like this, pull out before pin and traditional puncture procedure just the same (accompanying drawing 3), puncture complete pull out pin after (accompanying drawing 4), fix puncture needle handle 13, another hands on the other hand by sleeve cylinder handle 2 pushed forward to top, round platform funnel 9, needle tubing 11, syringe needle 10 is made to be inserted in needle tubing sleeve 1 successively, needle handle 13 is stuck is unlikely to slide anteroposterior along straight trough mouth 5, skew notch 6 shift-in direct neck 7, at this moment syringe needle 10 is covered by front card cylinder 4 is stable completely, can not prick into human body.
