Kind Code:
A1
Abstract:
A method for preparing a material for an artificial blood vessel, an artificial blood vessel prepared thereby and an application thereof. The preparation method comprises: dissolving a polymer in a solvent to obtain a spinning solution and an electrospray solution, using the spinning solution to perform electrospinning to obtain a porous electrospinning fiber inner layer, and then using the electrospray solution on the porous electrospinning fiber inner layer for multiple layers of electrosprayong to obtain a dense layer. The artificial blood vessel has excellent biocompatibility, blood compatibility and flexibility, and has the functions of preventing bleeding and being resistant to repeated puncturing. The preparation method is easy to operate, the production process is simple and easy to scale.
