Abstract

The invention relates to a base material used in degradable medical syringes as well as the preparation method, providing the degradable base material used in disposable syringe casing, core bar, needle stand and needle cap as well as the preparation method. The degradable base material is prepared with degradable macromolecule as main components, plasticizer, stabilizer, stabilizing adjuvant and filler at the weight percent of degradable macromolecule 100 portions, plasticizer 0 to 8 portions, stabilizer 0 to 4 portions, stabilizing adjuvant 0 to 8 portions and filler 0 to 35 portions. After being extruded and granulated, the finished products of granular materials are obtained. The base material of the degradable syringe has the advantages that the formula is reasonable, the process is simple and the property is stable, which is suitable for mass production in purification plant so as to replace the traditional base material for producing disposable syringes.

Description

technical field [0001] The invention belongs to the field of degradable disposable medical devices, and relates to a resin base material for a degradable medical syringe and a preparation method thereof. Background technique [0002] At present, most disposable syringes are made of materials such as polyvinyl chloride, polyethylene, and polypropylene. Discarded syringes cannot be degraded or destroyed in the natural environment, thus becoming medical waste, polluting the environment, and endangering people's health. Usually, centralized incineration and destruction are used to dispose of discarded syringes, which not only violates the principle of sustainable resource development. Moreover, after treatment, a large amount of black smoke, hydrogen chloride gas, and highly toxic dioxins and other substances will be produced, seriously polluting the environment. On the other hand, due to poor management of some medical institutions or driven by profit, disposable syringes are ...
