Description

Disposable vein blood taking needle

Technical field

It is the Medical treatment device for acquiring blood preparation at patient's vein the utility model relates to a kind of disposable vein blood taking needle Tool.

Background technique

It is pen type or split type vein blood taking needle that clinically application is very wide now, all be may cause in the two operating process Needle point accidentally stabs user, if using pen type blood collection both hands to cover process again cumbersome by nurse, easily by needle pricks, causes such as third The infection of the blood borne diseases such as liver, AIDS is using and is discarding recycling for split type blood taking needle, i.e. disposable blood taking needle It is also easily caused when disposition and stabs contactee.

Summary of the invention

The purpose of the utility model is to provide a kind of disposable vein blood taking needle, which is avoided that medical staff because of behaviour Make fault to cause the accident of needle pricks and damage contactee in clinical waste recycling, protects its safety Barrier.

The technical solution of the utility model is: disposable vein blood taking needle, the syringe needle having, it is characterised in that: syringe needle with Sliding block, plastic flexible pipe are sequentially connected, and sliding block handle is housed on sliding block, and sliding block handle protrudes shoe surface, and syringe needle and sliding block are mounted in In hollow shell, shell both ends of the surface have end cap or opening, and shell wall is axially arranged with the inside and outside skidway hole being connected to, skidway hole both ends Closing, and it is equipped with the locating slot of sliding block handle, sliding block handle passes through skidway hole and is placed in outside shell, and surface of shell is equipped with shell hand Handle.

The sliding block connects with one terminal filament of sliding block handle.The sliding block handle end face be equipped with it is convex stupefied or recessed stupefied, it is convex stupefied or It is recessed stupefied in the shape of the mouth as one speaks.

The utility model product keeps syringe needle scalable in shell, and needle point intrinsic energy is avoided that medical staff grasps in shell Needle pricks when making mistakes, alleviate the psychological pressure of medical staff, while having abandoned the plastic protective sleeve of traditional blood taking needle, tool There is safe and convenient, environmentally protective；Sliding block handle protrudes shoe surface, which can prevent syringe needle and sliding block to be detached from shell Body plays position-limiting action, instead of housing end plug；The locating slot of sliding block handle plays the role of locked needle position； It is located at the convex stupefied or recessed stupefied in the shape of the mouth as one speaks, the person of being convenient to operation front and back push-and-pull sliding block and left-right rotation sliding block of sliding block handle end face, is made It operates smooth；Made in blood sampling operation using shell handle capable of being, product overall stability is good；Shell both ends of the surface are openings, are conveniently torn open Fill syringe needle and sliding block, therefore the simple structure of the utility model, realize inexpensive high safety using vein blood taking needle Effect.

Specific embodiment

The rear end of disposable vein blood taking needle, the syringe needle 1 having, syringe needle is connect with 2 one end of sliding block, the sliding block other end and modeling Expect that hose 8 connects, sliding block is equipped with wire hole, and sliding block is connect by wire hole with 3, sliding block handle, and syringe needle and sliding block are mounted in hollow shell In body 6, shell both ends of the surface have end cap or opening, and shell wall is axially arranged with the inside and outside skidway hole 5 being connected to, and skidway hole is closed at both ends, Skidway hole upper and lower end is transversely provided with the locating slot 7 of sliding block handle, and sliding block handle protrudes from shoe surface, is placed in across skidway hole Outside shell, syringe needle and sliding block can be prevented to be detached from shell, play it in the intracorporal position-limiting action of shell, the sliding block handle end face Equipped with convex stupefied or recessed stupefied 9, it is convex stupefied or it is recessed it is stupefied be in the shape of the mouth as one speaks, the person of being convenient to operation pushes and pulls sliding block.Surface of shell and shell handle 4 are fixed Connection.

The course of work of disposable vein blood taking needle is: being placed in the lower positioning by plastic flexible pipe side using front-slider handle In slot, syringe needle is all placed in the state in shell, and when use pushes sliding block handle to leave lower locating slot into skidway hole, upwards Sliding slider handle, makes sliding block stretch out syringe needle therewith forward in shell, after sliding block handle reaches skidway hole top, by sliding block Handle, which is placed in locating slot, locks needle position, operation that blood was collected, after blood sampling operation, by sliding block handle out of upper locating slot It shifts onto skidway hole, and slide downward makes needle retraction shift lower locating slot onto the intracorporal original state of shell, and by sliding block handle It is interior.By syringe needle shell is intracorporal scalable and lock-bit, needle pricks accident caused by preventing operation error is realized.This is practical It is novel to be not limited to present embodiment, to those skilled in the art, without the simple copy of creative work Range protected by the claims of this utility model is belonged to improvement.
