| Objective:To evaluate the comprehensive physical properties of polyurethane artificial vascular graft. Methods:The axial tensile strength, circumferential tensile strength, film compression rupture strength, suture tension strength, strength after repeated puncture, water permeability and expanded inner diameter of the polyurethane artificial vascular graft were tested according to the method in the standard YY 0500-2004 Cardiovascular implants-Tubular vascular prostheses. Results:The mean values of each test item of the samples obtained in the experiment were as follows:axial tensile strength 770.81 N, circumferential tensile strength 6.71 N·mm-1, film compression rupture strength 294.78 kPa, suture tensile strength 34.89 N, strength after repeated puncture 2264 mmHg, water permeability 0 mL·min-1, and expanded inner diameter 2.20%. Conclusion:The enhanced polyurethane artificial vascular graft has better comprehensive physical properties and higher clinical application value. |
