Description
Technical field
The present invention relates to disposable use medical apparatus and instruments, especially relate to the anti-acupuncture venoclysis needle of disposable use.
Background technology
The disposable use venoclysis needle of domestic each clinical use of clinical unit of medical institutions; Mostly be and the supporting use of disposable infusion set; Mainly form by bottle plug puncture unit protective sleeve, bottle plug puncture unit, air filter, infusion tube, dropper, dropping funnel, flow regulator, liquid medicine filter and venoclysis needle; The venoclysis needle syringe needle is after using; Because the venoclysis needle syringe needle has protector exposed outside, be easy to stab and cause secondary pollution, particularly as like the syringe needle after the patient of disease, hepatitis B, hepatitis C etc. uses now to medical personnel or personnel's accident of handling medical waste; The existing on the market venoclysis needle that also has anti-acupuncture, but this series products all has certain defective, and be " Disposable Butterfly's Needle Safe Needle Guard " just existence of 03102395.9 like the patent No.: 1, operation inconvenience is difficult for observing blood back; 2, puncture back pin is difficult for fixing, and becomes flexible often to bring inconvenience to the nurse; The patent No. is that 02112068.4 " a kind of single wing transfusion syringe with safety device " also has problems: existing venoclysis needle assembling automatically is direct and needle handle assembly and the bonding assembling molding of needle stand through small hose; Add its safety device and be will small hose be penetrated from the endoporus of safety device and run through; So just be difficult to engage with prior art; The assembling existing automatization assembling that can not suit can not large-scale production; Other patent also all faces such several difficult.
Summary of the invention
The object of the present invention is to provide a kind of disposable use to prevent the acupuncture venoclysis needle; Can on the automatic built-up foundation of existing transfusion needle, accomplish assembling; Can under the prerequisite that does not change the origin operation method, observe blood back again; Can also after the medicinal liquid of being totally lost pulls out pin, can protect the transfusion needle syringe needle not expose, thus avoid patient with after the syringe needle accident stab and cause superinfection.
For realizing above-mentioned purpose; The present invention adopts following technical scheme: the present invention includes needle shield, puncture needle tubing, needle handle, small hose, needle stand, needle stand cock and anti-acupuncture sheath, puncture needle tubing, needle handle, small hose, needle stand are linked in sequence through adhesive, and needle shield is socketed on the needle handle; The needle stand cock is rotatably connected in the needle stand end; Anti-acupuncture sheath cutting ferrule is characterized in that on the small hose and can on small hose, slidably reciprocate: anti-acupuncture sheath be one from both sides folding press the back engaging to form, after the engaging; Its rear portion is a closed-loop, and the anterior sidewall upper edge of buckle has axially then formed a full of twists and turns line of rabbet joint.
Anti-acupuncture sheath is before engaging, and upper and lower cover can be that a side connects through the limit junction point, and the rear portion of both sides is provided with the buckle and the hole clipping of cooperation with it in addition.
Anti-acupuncture sheath also can be separately to be formed through buckle engaging both sides by upper and lower cover.
On the axial zigzag line of rabbet joint of anti-acupuncture sheath or lower wall be provided with non-return step, raised points and corresponding with it depression.
The limit junction point of anti-acupuncture sheath can be 2 or 3 or a plurality of.
The front portion of anti-acupuncture sheath is the oblique ellipse shape of an opening, not opening part on the limit junction point end, opening part is the starting point of the line of rabbet joint.
Anti-acupuncture venoclysis needle can not worn the needle stand cock, and direct and disposable infusion set assembling is used.
Because anti-acupuncture sheath is injection molded by renovating through once of two band inside grooves of junction point connection before assembling; It can will prevent that the acupuncture sheath is stuck on the small hose after being assembled into the common transfusion pin with needle shield, puncture needle tubing, needle handle, small hose, needle stand, needle stand cock; Also can after with needle shield, puncture needle tubing, needle handle, small hose, needle stand assembling, will prevent that the acupuncture sheath is stuck on the small hose, assembles the needle stand cock again.
The present invention is in operating process; Compare indistinction with the disposable use venoclysis needle of conventional use clinically; Just after pulling out pin, need pinch the snapped-in position of anti-acupuncture sheath on the other hand, other hands small hose of pulling back at anti-acupuncture sheath rear portion is pulled back needle handle to anti-acupuncture sheath; Can avoid patient to stab other people and cause infection, thereby strengthen protection medical personnel's safety with the pin accident of back band blood.
