Abstract

The invention discloses a medical perfusion tube material. The medical perfusion tube material comprises, by weight, 15-20 parts of PVC resin powder, 8-12 parts of oxidized polyethlene wax, 3-5 parts of polyamide resin, 0.5-0.7 parts of an organosilicon antifoaming agent, 4-6 parts of polyisoprene, 0.8-1 part of calcium-zinc paste, 2-4 parts of diisooctyl phenyl phosphate, 3-5 parts of glass fibers, 1.2-1.5 parts of octadecanamide, 0.4-0.6 parts of an anti-oxidant and 0.5 parts of benzyl silicone oil. The medical perfusion tube material utilizes medical PVC paste as a main raw material and other accessory materials. A medical perfusion tube prepared from the medical perfusion tube material has a low cost, is conducive to flame retardation and strength improvement, and has tensile strength of 130-135MPa, bending strength of 230-240MPa and excellent elasticity.

Description

technical field [0001] The invention belongs to the technical field of medical materials, in particular to a medical infusion tube material. Background technique [0002] Ordinary PVC infusion tubes also contain plasticizers, which increase the elasticity of the tubes and help maintain the accuracy of flow rate adjustment. At present, the plasticizer of the highly elastic precision filter infusion sets used in many hospitals is much higher than that of ordinary transparent tube infusion sets. During infusion, this plasticizer generally does not separate out from the tube material, only when infusion of paclitaxel chemotherapeutics, this DEHP plasticizer will obviously separate out. There is no need to add plasticizers to general plastic products, unless it is necessary to increase the elasticity of the plastic. [0003] Medical infusion tube is a general term for lumen products that connect the inside and outside of the human body. There are metal, plastic, rubber and oth...
