Description
Technical field
The present invention relates to the technical fields of medical equipment, espespecially spring back telescopic type safe blood-taking needle.
Background technique
China averagely receives injection 4.18 times for each person every year, receives for each person every year pollution utensil injection not 0.17 time, everyone
The annual utensil injection for receiving recycling is 0.04 time.It has been found that the pathogen that infection can be stabbed by needle include: hepatitis B, hepatitis,
Heptan liver, AIDS virus, herpe simplex, shingles zoster, Ebola/Marburg, dengue fever, creutzfeldt-Jacob disease, Bacillus abortus,
Bacterium diphtheriae, Neisseria gonorrhoeae, Leptospira icterohemorrhagiae, staphylococcus aureus, micrococcus scarlatinae knot
Pyrenomycetes etc..After the syringe needle piercing human vas observation of traditional blood taking needle has blood back, piercing needle is penetrated vacuum by medical staff
In the self-sealing rubber plug of heparin tube, it is connected to vacuum blood collection tube with blood taking needle.Blood is pre-formed inside vacuum blood collection tube to be born
Under pressure effect, it is pumped into vacuum blood collection tube by piercing needle.And take a blood sample and finish, blood collection needles are first extracted from patient's vein,
And blood collection needles are exposed to the external world after extracting, so that the pollution risk of risk and blood leakage that needle is stabbed is increased, to safety
Blood sampling brings many shortcomings.
Summary of the invention
It is mentioned above in the background art to solve the purpose of the present invention is to provide rebound telescopic type safe blood-taking needle
Problem.
To achieve the goals above, case is put in technology of the invention solution is: rebound telescopic type safe blood-taking needle, including protects
Sheath, needle point bar, rebound tube body, spring, push-and-pull bolt, needle handle body, heparin tube, lumen needle burr protect Membrane cover, handle, slide and lead to
Road, bolt position fixing groove；Needle handle body is made using medical grade plastic materials, handle, the top of needle handle body is arranged in the side of needle handle body
Setting rebound tube body, spring back tube body top setting protective case, spring back tube body side setting sliding channel, sliding channel it is upper
Portion side is equipped with bolt position fixing groove.
Needle point bar, the lower part side setting push-and-pull bolt of needle point bar, the outside of needle point bar is arranged in the rebound tubular body
Lumen needle burr is set and protects Membrane cover, the outside that lumen needle burr protects Membrane cover is equipped with spring；The center that heparin tube passes through needle handle body is logical
Road is connect with the lower part of needle point bar.
Advantageous effect of the invention is: shifting bolt by sliding channel using by the push-and-pull bolt of needle handle body top rebound tube body side
In the fixing groove of position, blood sampling syringe needl can be formed effectively by needle point bar by releasing in protective case；And after the completion of taking a blood sample, pulling out needle only needs
Push-and-pull bolt is turned back into sliding channel, needle point bar can be made to be sprung back rapidly into rebound tube body under the action of the spring, have and pull out needle
Speed is fast, more at the uniform velocity, reaches painless the advantages of quickly pulling out needle, avoids needle point bar exposed outside easily to causing injured again lack
It falls into, and this rebound telescopic type safe blood-taking needle is disposable product, can directly be destroyed using behind outside, is ideal disposable
Rebound telescopic type safe blood-taking needle.
Detailed description of the invention
Utility model invention is further described with reference to the accompanying drawings and detailed description.
The appearance diagram of the rebound telescopic type safe blood-taking needle of attached drawing 1；
The structural schematic diagram of the rebound telescopic type safe blood-taking needle of attached drawing 2.
In figure: 1, protective case, 2, needle point bar, 3, rebound tube body, 4, spring, 5, push-and-pull bolt, 6, needle handle body, 7, heparin tube,
8, lumen needle burr protects Membrane cover, 9, handle, 10, sliding channel, 11, bolt position fixing groove.
Specific embodiment
As shown in attached drawing 1,2, telescopic type safe blood-taking needle, including protective case 1, needle point bar 2, rebound tube body 3, bullet are sprung back
Spring 4, push-and-pull bolt 5, needle handle body 6, heparin tube 7, lumen needle burr protect Membrane cover 8, handle 9, sliding channel 10, bolt position fixing groove 11；
Needle handle body 6 is made using medical grade plastic materials, handle 9, the top setting rebound pipe of needle handle body 6 is arranged in the side of needle handle body 6
Protective case 1 is arranged in body 3, the top of rebound tube body 3, and sliding channel 10, the top of sliding channel 10 is arranged in the side of rebound tube body 3
Side is equipped with bolt position fixing groove 11.
Needle point bar 2 is set inside the rebound tube body 3, and the lower part side setting of needle point bar 2 pushes and pulls bolt 5, needle point bar 2
Outside setting lumen needle burr protects Membrane cover 8, and the outside that lumen needle burr protects Membrane cover 8 is equipped with spring 4；Heparin tube passes through needle handle body 6
Central passage connect with the lower part of needle point bar 2.
Working principle of the present invention: in blood sampling operation, by the push-and-pull bolt 5 of 6 top of needle handle body rebound 3 side of tube body, by returning
The sliding channel 10 of 3 side of bomb tube body is shifted onto the bolt position fixing groove 11 on top and is fixed, needle point bar 2 also with push-and-pull bolt
5 promotion can form blood sampling syringe needl by releasing in protective case 1；After the completion of blood sampling, push-and-pull bolt 5 need to only be turned back when pulling out needle
Sliding channel 10, needle point bar 2 is sprung back rapidly under the action of spring 4 into rebound tube body 3, and the speed ratio that spring 4 is sprung back
Manually pull out needle speed fastly, more at the uniform velocity, i.e., avoidable needle point bar 2 is exposed to easily cause injury again outside, and can reach without delighted
Speed is pulled out the advantages of needle, and needle point bar 2 after use springs back the rebound tube body 3 of inserting needle shank body 6, make needle point bar 2 completely it is not exposed outside,
And the lumen needle burr of the outside of needle point bar 2 protects Membrane cover 8, can prevent the contact of spring 4 with needle point bar 2, it is ensured that needle point bar safety
Property.
The above, embodiment is only that preferred embodiments of the present invention will be described, not to of the invention
Range is defined, and under the premise of not departing from the spirit of the technology of the present invention, this field engineers and technicians are to skill of the invention
The various changes and improvements that art scheme is made, should fall within the scope of protection determined by the claims of the present invention.
