Abstract

The invention relates to a transparent medical PVC material suitable for wide-wave shading and a preparation method thereof. The PVC material is composed of, by weight, 100 parts of suspension-method PVC resin, 50-75 parts of plasticizers DEHP and TOTM, 1.0-2.0 parts of a Ca/Zn thermal stabilizer, 8-12 parts of an auxiliary thermal stabilizer, 0.5-1.0 part of a lubricant and 0.01-0.05 parts of a shading agent. The shading wave length range of the PVC material is increased to 220-550 nm and the light transmittance reaches not less than 0%. The PVC material solves the problems of narrow shading range (220-450 nm) and low light transmittance (less than 30%) which exist in the shading medical PVC materials in the prior art, thereby satisfying the higher clinical application demands in a shading transfusion device.

Description

technical field [0001] The invention relates to a modification technology of a medical PVC material, in particular to a transparent medical PVC material suitable for wide-wave light protection and a preparation method thereof. Background technique [0002] Medical PVC material is the most widely used raw material for disposable medical device consumables at home and abroad. Due to the advantages of good comprehensive performance and high cost performance, PVC materials are more and more widely used in disposable medical devices, among which the application of infusion sets is the most important. However, it has been clinically found that many drugs have special molecular structures that absorb light energy when they are used in ordinary non-light-proof infusion sets. Especially because the light energy in the ultraviolet region is large, reactions such as decomposition and oxidation occur, resulting in the occurrence of drug components. change, reduce or lose the due curati...
