Embodiment Construction

[0043] The process of producing disposable self-degradable medical injection equipment and other medical supplies with plant straw as raw material is:

[0044] (1) Raw material pretreatment and saccharification: first clean the plant straw, cut it into pieces with a cutting machine and grind it into a slurry, then add an appropriate amount of water to the air-lift fermenter, and then put the ground plant straw The slurry flows into the fermenter according to the weight ratio of 36-49%, and then add enough water in the weight ratio. After adjusting the pH value of the tank liquid to 6.4, the tank temperature is slowly raised to 100°C, and the tank temperature is lowered after 8-20 minutes. Drop to 70°C, flow in 2-5% cellulase to destroy the crude tissue fiber of the straw, and make the straw slurry preliminary saccharification, after 20-40min the initial saccharification is completed, flow in 0.5-3% saccharification enzyme for further saccharification 20- 40min, make its stalk ...

Abstract

The disposable medicine utensil is produced with grain, tomato and sugar producing leftover and crop stalk as main material and through saccharification, bacterial fermentation, separating extraction of lactic acid, dewatering and condensation to form lactic acid material, extrusion, pelletizing, and molding. The utensil is degradable, capable of being self destroyed to prevent secondary infection, safe, reliable, low in cost, being superior to plastic product.

Description

technical field [0001] The invention relates to the technical field of environmentally friendly degradable disposable medical injection equipment. Background technique [0002] The existing disposable medical syringes, infusion sets and some medical products are mostly made of polyethylene and polypropylene and other materials through blow molding. The medical products made of these materials cannot be destroyed and destroyed by themselves after use. It will be degraded and destroyed by itself, turning it into medical waste, polluting the environment and endangering people's health. Usually, the method of disposing of these used disposable medical appliances is to adopt the method of centralized burning, which not only wastes precious oil resources, but also produces a large amount of black smoke and hydrogen chloride gas, and also produces what is currently considered to be The most toxic dioxin-like highly toxic substances pollute our human living environment. What's mor...
