Abstract

The invention discloses a preparation method of a composition for a blood transfusion set. The preparation method includes: adding PVC, lubricant and stabilizer into a mixer according to a certain ratio of raw materials, controlling the temperature not higher than 95°C, stirring at not higher than 100r / min, and adding plasticizer after mixing evenly, at 250r / min Stir and mix evenly; add stabilizer and epoxidized soybean oil to the mixer, continue to stir and mix evenly at the same speed and temperature; put the mixed material into the extruder, control the temperature at 100-140°C, and carry out granulation. In the composition for preparing blood transfusion apparatuses of the present invention, each preparation component is environmentally friendly and non-toxic, has good use effect, is healthy for the body, is convenient to use, and is suitable for making blood transfusion apparatus. The preparation method of the present invention has few steps, simple operation, less input and quick effect; the prepared vessel is used for storing blood, and the blood is stable and reliable.

Description

technical field [0001] The invention relates to a blood transfusion set, in particular to a method for preparing a composition for a blood transfusion set. Background technique [0002] Plastic blood bags refer to plastic bags used in the collection, separation, storage and transfusion of human blood and its components. The blood bag should be colorless, transparent, soft, airtight, sterile, non-toxic, and sterilizable. During storage, the blood bag components in the anticoagulant or leachable substances in the blood must meet the limits allowed in the standard regulations. , and limit the toxicity to the blood and the impact on the patient to the greatest extent. The materials used for plastic blood bags are mainly plasticized soft PVC plastics, and there are also materials made of polyolefin thermoplastic elastomers. [0003] PVC-DEHP blood bags are widely used in the storage of whole blood and concentrated red blood cells. Studies suggest that a small amount of DEHP le...
