Embodiment Construction

[0006] The following examples further illustrate the invention.

[0007] 1. Preparation of lactic acid: Using starch as raw material, it is decomposed into glucose by amylase, and then fermented into lactic acid by lactic acid bacteria.

[0008] 2. Synthesis of polylactic acid: lactic acid is prepared into polylactic acid in the presence of a catalyst.

[0009] 3. Polylactic acid is processed by plastic film blowing machine and injection molding machine to prepare various medical equipment products.

Abstract

The present invention relates to a producing technique of degradable medical device. The polylactic acid is taken as raw material and is processed with a plastic film blowing machine and a plastic injection machine for producing various medical devices. The medical device can be easily and totally degraded in natural environment and therefore has the advantages of no pollution, energy conservation, and actual green environment protection.

Description

Technical field [0001] The present invention is a production process of a degradable medical device, and particularly relates to a production process of a degradable medical device prepared by using polylactic acid as a material. Background technique [0002] Nowadays, there are more and more disposable medical devices. The waste of these disposable medical devices is bound to cause great pollution and pressure to the environment. Therefore, the invention of degradable medical devices is very important. [0003] Patent No. 91101274.5 is now published by the State Patent Office. Title: New material composition method for syringes. It is characterized in that: after the syringe is discarded, the material for manufacturing the syringe is a material that decomposes naturally, or this type of material is composited with other materials. The material is composed of paper material and non-toxic, waterproof membrane compound or paper material and non-toxic, waterproof material and other ...
