Description
Technical field
The utility model belongs to medical instruments field, more particularly, to a kind of anti-stab injection needle.
Background technology
In clinical position, it is a kind of doctor trained in Western medicine commonly treatment means, injection needle to inject drug and blood test to patient
Include mainly muscle injector needle, intravenous needle, these clinical syringe needles such as venous detaining needle are all hollow stainless pins,
Very sharp, medical staff accidentally accidentally stabs the thing of oneself and happens occasionally, suffer from after carrying out puncture for treating to patient and extracting needle
Various germs are all usually carried in the body fluid and blood of person, the puncture needle after being contaminated is pierced into medical staff and undoubtedly can
It is impacted to the health of medical staff, if in addition, outcast puncture needle needle point is exposed to outer, is also easy to stab medical treatment useless
The collection of gurry and treatment people can also impact their health, although currently, puncture needle is equipped with dedicated needle
Set, after use, medical staff can be sleeved on needle guard on puncture needle, still, since the bore of needle guard is smaller, be less susceptible to pair
Standard, the case where still stabbing medical staff's finger frequent occurrence, Authorization Notice No. is:A China of 205095167 U of CN is real
It is disclosed a kind of " anti-stab needle guard " with new patent, including the needle guard piece of cladding syringe needle and needle body can be formed after two panels closure, it can
When in use syringe needle cladding to get up to use, syringe needle is retracted into needle guard again after using, and lock and protected, from
And avoid stabbing nursing staff, this " anti-stab needle guard " although can solve the problems, such as accidentally to stab, structure is complex, at
This height, operation is also not convenient enough, and application publication number is:A Chinese invention patent of 105833388 A of CN discloses " a kind of
Puncture needle can be hidden in casing, by the way that remaining needle security component is arranged so as to avoid piercing by safety indwelling needle "
The puncture needle of patient hurt operator or other people, increase the safety that remaining needle uses, but this safety indwelling needle
Structure it is relatively complicated, in addition, also have after piercing, the button in remaining needle is set to by pressing, will by spring
Interior needle pulls in inside needle guard, is received in wherein (such as JP Laid-Open 10-52499 documents, patent application publication CN
102512728A);Also spring needle point protection mechanism is set to the inside of outer Needle sleeve, passes through needle in extraction, needle point protection
Mechanism is detached from outer Needle sleeve, and the front end of interior needle is covered (such as patent publication No. CN 101011613A);These are all needed
It to be realized using to spring, if spring can not be successfully deformation reset, cannot achieve the protection to draw point needle point, therefore not enough
Reliably, currently, lacking a kind of anti-stab injection needle safe and reliable, simple in structure, easy to use.
Invention content
The technical problem to be solved by the utility model is to provide a kind of anti-stab injection needles, without being directed at needle guard after use,
Spring is not used, so that it may easily injection needle to be nested into needle guard, not only securely and reliably, use more square yet yet
Just, and structure is also simpler, at low cost.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is:Including needle stand, needle body and needle point,
It is characterized in that:It is equipped with telescopic in the outside of the needle body and the junction of needle stand, set is equipped in the other end of telescopic
Cap.
The telescopic can be made of elastic material, prick needle point on cap bag after stretching.
It may be plastic material, longitudinal telescopic crack be equipped at the middle part of telescopic, needle body is by splitting after stretching
Seam pulls in needle guard, then needle point is pricked on cap bag.
As the improvement project of above-mentioned second of technical solution, upper breach is equipped in the upper end in the telescopic crack
Hole is equipped with lower breach hole in the lower end in telescopic crack, and needle body is easier to be reduced in telescopic.
As a further improvement, being equipped with lateral upper breach at the upper breach hole, cross is equipped at lower breach hole
To lower breach, it is easier to fold.
As further improving, the middle section between the upper breach and lower breach is equipped with eight word mouths, telescopic
Middle part be easier fold.
As further improving, it is equipped with handle in the side of the cap bag, it is more difficult to prick the hand.
The utility model is equipped with telescopic by the junction in the outside of needle body and needle stand, is set in the other end of telescopic
There is cap bag, before use, telescopic and cap bag all contract in the rear end of needle body, does not influence the normal use of injection needle, injection needle is extracted
Afterwards, cap bag is pinched with finger, needle body is pulled in telescopic, needle point is penetrated on cap bag, prevent from accidentally stabbing medical staff
And related personnel, compared with prior art, the utility model does not influence the normal use of injection needle, without being directed at needle guard, not yet
Use spring, so that it may easily injection needle to be nested into needle guard, can not only prevent the infection of disease, operate also more
Add conveniently, and structure is also simpler, cost is cheaper.
