Abstract

The invention relates to a polyvinyl chloride composite for an extracorporeal circulation pipeline of an artificial heart-lung machine. The polyvinyl chloride composite consists of polyvinyl chloride resin, a plasticizer, a stabilizer and a lubricant, and specifically consists of the following components in parts by mass: 100 parts of polyvinyl chloride resin, 30-60 parts of cyclohexane 1,2-diisononyl diformate plasticizer, 0.5-5 parts of stabilizer organic tin or calcium-zinc stabilizer, 5-10 parts of epoxidized soybean oil stabilizer and 0.2-5 parts of lubricant. The polyvinyl chloride composite provided by the invention has the advantages of reasonable formula, stable performance, simple process, low cost and good biocompatibility and is non-toxic and safe. Large-batch production can be performed in a clean room. The product meets the requirements on the extracorporeal circulation pipeline-series products of an artificial heart-lung machine of a cardiopulmonary bypass system.

Description

technical field [0001] The invention relates to the field of medical polymer materials, in particular to a polyvinyl chloride composite material for an artificial heart-lung machine extracorporeal circulation pipeline. It is a polyvinyl chloride (PVC) material that does not contain DEHP (ortho-phthalic plasticizer), and this material can be applied to a series of products of cardiopulmonary bypass system artificial heart-lung machine extracorporeal circulation pipelines. Background technique [0002] Extracorporeal circulation of the cardiopulmonary bypass system refers to the whole process of connecting the large blood vessels of the human body with the artificial heart-lung machine through artificial pipelines, drawing venous blood from the venous system, oxygenating it outside the body, and then returning the oxygenated blood to the arterial system through a blood pump. Applied to human heart and great vessel surgery. The raw material of extracorporeal circulation pipeli...
