Problems solved by technology

[0002] At present, the PVC material itself is relatively hard. After adding a plasticizer, PVC becomes soft and elastic, easy to form and process, and can be made into medical products of various shapes, because it has become a widely used method for making medical products. Materials. At present, ordinary plastic blood bags used to store platelets in China have the following problems. The air permeability is not good. Platelets need oxygen to breathe and emit carbon dioxide. The oxygen permeability of ordinary plastic blood bags is far below the standard requirements. A large amount of DEHP is used for plasticization. The precipitation of DEHP will increase the pH value of the platelet concentrate, resulting in the death of some platelets, which is not conducive to the preservation of platelets. At the same time, ordinary plastic blood bags have poor low temperature resistance and are not good for platelets. Preservation

Abstract

The invention discloses a medical thin-film material. Polyvinylchloride resin and epoxy resin serve as raw materials and are mixed with a lubricant, corn starch, a sensitizing agent, a surfactant and an anti-bonding agent. The medical thin-film material is prepared from the raw materials in parts by weight as follows: 40-50 parts of polyvinylchloride resin, 20-30 parts of epoxy resin, 1-3 parts of the lubricant, 5-8 parts of the corn starch, 0.5-1.5 parts of the sensitizing agent, 2-4 parts of the surfactant and 0.8-1.3 parts of the anti-bonding agent. The medical thin-film material has the benefits as follows: polyvinylchloride resin and epoxy resin serve as the main raw materials and are mixed with other ingredients, the breathable effect of a thin film can be guaranteed effectively, the medical thin-film material is good in elasticity and stable in performance, and the quality of the thin film is improved and meets the medical requirement.
