23 Jul Preparation method of oriented fiber reinforced artificial blood vessel
Abstract
The invention relates to a preparation method of oriented fiber reinforced artificial blood vessel, belonging to the technical field of tissue engineering, including the steps: at first, a lay of polyurethane solution is painted on the surface of the blood vessel mold, then the fiber material is arranged on the surface of the polyurethane solution according to a certain direction to form an aligned fib layer, and then a nano film is formed on the surface of the aligned fiber layer through electrostatic spinning, so that the artificial blood vessel with good alignment degree is prepared. The biocompatibility of the prosthesis made by this method is good. The orientation arrangement of the fibers in the prosthesis is conducive to the orderly growth and arrangement of the cells in the prosthesis. The preparation process is relatively safe and the preparation efficiency is high.
