Description
Technical field
The present invention relates to the degradable disponsable medical instruments field, specifically, relate to degradation type disposable syringe and preparation method.
Background technology
At present, disposable syringe uses materials such as polrvinyl chloride, polyethylene and polypropylene to make mostly, and depleted syringe can not degrade in natural environment or destroy voluntarily, thereby becomes medical waste, contaminated environment, and the harm people's is healthy.Usually the ways that adopt concentrated burning to destroy are handled depleted syringe more, and this method is not only run counter to the principle of resources sustainable development.And after handling, can produce materials such as a large amount of black smokes, hydrogen chloride gas and supervirulent dioxin, serious environment pollution.On the other hand, because mismanagement of part medical institutions or interests are ordered about, disposable syringe is illegally reclaimed, is peddled and reused.The repeated use of syringe has stayed hidden danger to cross infection, causes pathophoresiss such as hepatitis B, acquired immune deficiency syndrome (AIDS).For this reason, the Chinese government endeavours to promote self-destructive syringe, but its complex structure, manufacturing cost height, promoting the use of of it has been subjected to restriction to a certain extent.For these reasons, the exploitation degradation type disposable syringe is not only avoided discarded syringe contaminated environment, and is economized on resources, and can also really realize the once use of disposable syringe.At present, about the research of degradation type disposable syringe with report less.Have only Chinese patent CN 2776433Y only to disclose the new construction of degradation-type self-destroyed syringe, this syringe needle is arranged on the overcoat front end, form integrative-structure with overcoat, piston is installed in the core bar front portion, the core bar front end flexibly connects conical the core of the card, the top is provided with the conical draw-in groove that cooperates with the core of the card in the overcoat, can realize with the back self-destruction.Syringe only is a carbon dioxide copolymer with base material in this patent, the preparation of unexposed corresponding base material, pelletize and syringe moulding process.
Summary of the invention
Innovation part of the present invention is: prepared complete degradation-type syringe, it is made of overcoat, core bar, needle stand and needle cap, and every performance of the degradation-type syringe that obtains meets national standard " disposable sterilized syringe (GB 15810-2001) " fully.The syringe preparation technology of this disclosure of the Invention is detailed rationally, and the Biodegradable syringe that obtains really possesses application prospect.
The present invention's first purpose provides degradation type disposable syringe.
The present invention's second purpose provides the preparation method of degradation type disposable syringe.
Degradation type disposable syringe provided by the invention, as shown in Figure 1, it constitutes needle cap 1, needle stand 2, core bar 3 and overcoat 4, all can degraded fully in natural environment.
