Abstract

The invention provides a disposable safe self-destroying syringe. The disposable safe self-destroying syringe is mainly composed of a syringe body, a core rod, a leading-out part, a needle base and an entry needle. The disposable safe self-destroying syringe is characterized in that a safe self-destroying component is a safe self-destroying device formed by combining the syringe body 3, the core rod 2, a rubber plug 7, the leading-out part 8, an O-shaped sealing ring 9 and the needle base 10. The disposable safe self-destroying syringe is reasonable in structure, simple in assembling technology, convenient to use, good in safety performance and capable of being self-destroyed after one-time injection, and cannot be repaired or used after self-destroying, and the cross infection possibility caused by reusing is avoided.

Description

Disposable use safety self-destructing syringe

One, technical field

The present invention relates to a kind of medical apparatus and instruments articles for use, especially a kind of safety self-destructing syringe.

Two, background technology

China since last century the eighties promote the use of disposable syringe, so far existing nearly 30 years history, in clinical injection application, play positive role to guarding against cross infection, but also there are the irresponsible medical personnel of only a few that disposable syringe is reused, bring unexpected hidden danger and incalculable consequence to sufferer.For this reason, cannot have more significance by reusable safety self-destructing syringe after developing a kind of disposable use.

Three, summary of the invention

The object of the invention is: reusable safety self-destructing syringe is again provided after a kind of disposable use.

In order to achieve the above object, technical scheme of the present invention is: a kind of disposable use safety self-destructing syringe, is mainly made up of cylindrical shell, core bar, leading-out piece, needle stand body, entry needle; It is characterized in that: safety self-destruct parts are by cylindrical shell, core bar, plug, leading-out piece, O RunddichtringO, needle stand body, are together to form a safe self-destruction device.

Described disposable use safety self-destructing syringe, is characterized in that: in cylindrical shell, be provided with the screens of claw retaining and anti-rotation retaining draw-in groove.

Described disposable use safety self-destructing syringe, is characterized in that: core bar is provided with the claw, clip and the core bar that can elasticity the open place that fractures.

Described disposable use safety self-destructing syringe, is characterized in that: leading-out piece be provided with card, can folding lower card and medicine liquid channel.

Described disposable use safety self-destructing syringe, is characterized in that: on needle stand body, be equipped with Ka Tai, anti-rotation retaining muscle, female Luer and lay the groove of sealing ring.

Operation principle of the present invention is: in the time that entry needle is installed, entry needle is threaded connection in the female Luer of needle stand body, because of the draw-in groove effect on card muscle and the cylindrical shell of needle stand body, can prevent from can not making needle stand body to rotate in the time tightening entry needle, in the time taking out medicinal liquid, due to the card muscle of needle stand body and the stopping function of cylindrical shell draw-in groove, can stop needle stand body needle stand body to be taken back to cylindrical shell because of the suction force of taking out medicinal liquid, meanwhile, because of the O RunddichtringO sealing function on needle stand body, make the medicinal liquid can seepage.When injection, medicinal liquid flows out by the medicine liquid channel of leading-out piece, after injection, leading-out piece can folding under block the Ka Tai of needle stand body, along with retreating of core bar, needle stand body is taken back in cylindrical shell and is concealed by force together with entry needle, in the time that core bar is repositioned to the retaining screens on cylindrical shell, claw on core bar opens because of elasticity, is stuck in screens, and core bar is no longer drawn out, can not before push away, then a folding gently, core bar just fractures at the core bar place of fractureing, thereby reaches safety self-destruct object.

The invention has the beneficial effects as follows: use simple, convenient, safety, after disposable use, cannot reuse again, stoped the cross infection in clinical injection.

Five, detailed description of the invention

The disposable use safety self-destructing syringe of the present invention, as shown in Figures 1 to 8: a kind of disposable use safety self-destructing syringe, is mainly made up of cylindrical shell, core bar, leading-out piece, needle stand body, entry needle; It is characterized in that: safety self-destruct parts are by cylindrical shell 3, core bar 2, plug 7, leading-out piece 8, O RunddichtringO 9, needle stand body 10, are together to form a safe self-destruction device.In cylindrical shell 3, be provided with claw retaining screens 1 and anti-rotation retaining draw-in groove 16; Core bar 2 is provided with the claw 5, the clip 13 that can elasticity open, the core bar place 4 that fractures; Leading-out piece 8 be provided with card 6, can folding lower card 11 and medicine liquid channel 15; On needle stand body 10, be equipped with card platform 14, anti-rotation retaining muscle 17, female Luer 12 and lay the groove 19 of sealing ring, female Luer 12 is for connecting entry needle 18.

When assembling, the present invention first cylindrical shell 3 and needle stand body 10 are installed, because anti-rotation locking card muscle 17 on needle stand body 3 does not close fixing with the anti-rotation retaining draw-in groove on cylindrical shell, entry needle hour hands pedestal is installed and can not be rotated, O RunddichtringO 9 is placed in groove 19, makes the medicinal liquid can seepage.Leading-out piece 8 through plug 7 by leading-out piece, block 6 be stuck in core bar 2 can folding clip 13 on, when injection, medicinal liquid is carried through the medicine liquid channel 15 of leading-out piece, after injection, leading-out piece 8 can folding under block 11 and open because of elasticity, block the card platform 14 of needle stand body 10.Along with the post-tensioning of core bar 2 is taken back needle stand body in cylindrical shell and concealed by force together with entry needle 18, in the time that core bar is repositioned to the retaining screens 1 on cylindrical shell, claw 5 on core bar opens because of elasticity, be stuck in retaining screens 1, core bar is no longer drawn out, can not before push away, a then folding gently, core bar just fractures at the core bar place of fractureing, thereby reaches safety self-destruct object.

The present invention is rational in infrastructure, simple for assembly process, easy to use, and security performance is good, gets final product self-destruction after a shot, after self-destruction, cannot repair use, has avoided reusing and the cross infection that may cause.
