Description
Technical field
The present invention relates to safety self-destructing syringe; be specifically related to a kind of safety self-destructing syringe with needle guard mechanisms, especially can prevent from that syringe needle that the medical apparatus and instruments such as syringe are used from meeting accident after use to stab medical care or cleanup crew and syringe and reuse.
Background technology
Use in a large number on the market at present and sell remain traditional disposable syringe, because it does not possess safety and self-destroying function, particularly because accidental puncture, illegal recovery, reusable phenomenon are difficult to wipe out, cause the potential safety hazard in clinical use, brought problem also to harmless treatment thereafter.
In medical practice, with the medical apparatus and instruments of sharp-pointed syringe needle, use very extensively, such as syringe, hemostix etc.These medical apparatus and instruments are not only and in medical institutions, by professional, are used and process, but also usually by layman, are used in the family and processed.
The multiple disposable syringe major part of prior art is being taken apart after packing, outside syringe needle is exposed to, and injects complete, outside syringe needle is exposed to equally, be easy to stab related personnel, cause very large difficulty to medical care or cleanup crew's collection and treatment, this stabbing also can cause bacteria infection; Meanwhile, used disposable syringe is easy to illegally be reclaimed, reuse by lawless person.
In order to prevent the generation of accidental puncture and to reuse, people have proposed the syringe that uses rear syringe needle to retract.Although this syringe has solved the problem of easily stabbing medical personnel's hands, this syringe construction complexity, cost is high, malfunction.
Summary of the invention
The object of the invention is to: a kind of safety self-destructing syringe is provided, simple structure, easy to operate, self-destruction be protected and be completed to safety and environmental protection can to the needle point polluting after injection finishes, and prevents that again scathing and syringe reuse.
Technical solution of the present invention is: this safety self-destructing syringe comprises helmet, syringe needle, cylindrical shell, push rod and needle guard mechanisms, described syringe needle comprises needle stand and is arranged on the needle point on needle stand, helmet is fixed on syringe needle, syringe needle is arranged on the front end of cylindrical shell by needle guard mechanisms, with the push rod of zero type circle piston, be arranged in the hollow cavity of cylindrical shell, entirety forms safety self-destructing syringe; Described needle guard mechanisms comprises 6:100 Rule adaptor that entry needle and cylindrical shell can be linked together, syringe needle can be received in to inner protection arm, can stably needle guard mechanisms be positioned to hinge and the buckle of various desired location; Described hinge injection moulding is connected between 6:100 Rule adaptor upper end periphery and protection arm proximal end bottom surface, and described protection arm is rotated with respect to described 6:100 Rule adaptor.
Wherein, at least two elasticity support claws of symmetrical molding of described barrel front end conehead inner chamber.
Wherein, described push rod connects push rod back segment by push rod leading portion through changeover portion and forms, changeover portion comprises protruding bracing frame and recessed bracing frame, the top molding push-pull ring of push rod leading portion, injection moulding all-in-one-piece grab is established in the end face center of circle of push-pull ring, the frustum that the molding of grab head and elasticity support claw fasten, between the epimere of push-pull ring and hypomere, be provided with the groove that zero type circle piston is installed, the protruding bracing frame of bottom centre's injection mo(u)lding of push rod leading portion, the recessed bracing frame of top injection mo(u)lding of push rod back segment, protruding bracing frame is positioned at recessed bracing frame and connects into Integer push rod through easy breakpoint injection moulding.
Wherein, on described push rod, at least establish four easy breakpoints, easily breakpoint is set in parallel on the coaxial symmetrical blading of push rod, easily and the gap on recessed bracing frame top and protruding bracing frame top, the baseplane of protruding bracing frame at breakpoint place equates with the gap of recessed bracing frame bottom, and gap is within the scope of each easily broken point deformation.
Wherein, described push-pull ring epimere diameter is slightly less than injector cartridge internal diameter, and push-pull ring hypomere diameter equals injector cartridge nozzle diameter, and the end face A of push-pull ring is plane or is the conical surface, depending on injector cartridge end shape, determines.
Wherein, described groove is square or for arc, the internal diameter of groove equals zero type circle piston inner diameter, and the width of groove equals zero type circle piston wire diameter, and the degree of depth of groove is slightly larger than the half of zero type circle piston wire diameter.
Wherein, described zero type circle piston is injection molded by medical plastic or medical grade rubber material, and between zero type circle piston and cylinder inboard wall, by zero type circle outer ring surface sealing, zero type circle outer ring surface can be also two seals ring or multiple-sealed ring.
Wherein, described 6:100 Rule adaptor comprises 6:100 Rule screw joint and 6:100 Luer inner conical connector.
Wherein, described hinge comprises the hinge, weakening structure and the V-arrangement shell fragment that by injection moulding, form; hinge is symmetrically distributed in V-arrangement shell fragment both sides; between hinge and hinge, by weakening structure injection moulding, be connected; V-arrangement shell fragment two ends are connected by weakening structure injection moulding with 6:100 Rule adaptor and protection arm respectively; entirety forms hinge; hinge and 6:100 Rule adaptor, protection arm are one; hinge is a part for 6:100 Rule cone joint or protection arm in other words, its two ends respectively with 6:100 Rule adaptor and fixing the combining of protection arm.
