Description

Anti-stab injection needle

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.
