Abstract

The invention discloses a medical PVC material with high oxygen permeability for platelet storage and a preparation method thereof. The material comprises the following components by weight: 100 parts of polyvinyl chloride resin, 45-60 parts of a plasticizer, 5-10 parts of a heat stabilizer, 0.1-2 parts of a lubricant, 0.1-0.5 part of a functional additive of sodium lactate. The invention has the advantages of reasonable formula, stable performance, simple process and low cost, effectively improves the oxygen permeability of platelet storage bag, prolongs the storage life of platelets, and is of great practical significance to the development of medical and health undertakings in our country and even the world.

Description

technical field [0001] The invention relates to a modified polyvinyl chloride (PVC) material and a preparation method thereof, in particular to high oxygen-permeable platelets without phthalate (2-ethylhexyl) (DEHP) plasticizers Storage of medical PVC materials. Background technique [0002] With the rapid development of my country's medical and health services, the demand for disposable infusion (blood) sets and other medical supplies continues to rise. It is estimated that nearly 15 million sets of blood bags are used in my country every year, and the plastic base material can reach tens of thousands of tons. Although the current research in the fields of medical polypropylene, polyethylene, elastomer, polyester and nylon has made some progress, due to its superior comprehensive performance and relatively low price, PVC medical pellets are still used in the production of disposable transfusion (blood) and so on. One of the main raw materials for supplies. So far, there ...
