| titleOfInvention | Preparation method of fiber-based artificial blood vessel |
| abstract | The invention provides a fiber-based artificial blood vessel and a preparation method thereof, belonging to the field of biomedical engineering. The method comprises the steps of firstly extruding a mixed solution of polycaprolactone and polyurethane by a metering pump, pre-coagulating by a coagulating bath, then winding by a rotary cylindrical die, and soaking and drying to obtain a winding layer; spraying N, N-dimethylformamide on the winding layer to obtain a solvent layer; then taking the obtained product as an electrostatic spinning receiving end, carrying out electrostatic spinning, and soaking and drying to obtain an electrostatic spinning layer; and spraying N, N-dimethylformamide on the electrostatic spinning layer, and repeating the steps once in sequence to obtain the fiber-based artificial blood vessel. The invention sprays N, N-dimethyl formamide between fiber layers, improves the compatibility between fiber layers and increases the axial strength of the artificial blood vessel. The artificial blood vessel manufactured by the invention has simple process, good mechanical property, permeability resistance and biocompatibility, and is expected to be produced in a large scale. |
