Description

A kind of preparation method of fiber artificial's blood vessel
Technical field
Present invention relates particularly to a kind of preparation method of fiber artificial's blood vessel.
Background technology
Artificial blood vessel is the substitute of many Serious Stenosis or artery occlusive, is with nylon, terylene mostly（Dacron）, it is poly- Four fluorine ethylenes（PTFE）It is made Deng synthetic material, it is adaptable to the bypass art of whole body everywhere, big, the artificial blood of medium caliber Pipe is applied to clinic and has obtained satisfied effect.Angiocardiopathy is to endanger one of common disease of human health, than more serious Patient, the treatment means of its main and auxiliary are vasotransplantation, and therefore autologous vein limited source, clinically needs big The artificial blood vessel of amount is used as graft substitute.During angiorrhoxis in human body, the artificial blood vessel of portable polyester material, but due to Blood is easily set in artificial blood vessel's inwall, if artificial blood vessel is carefully easy for very much blocking, this is always exploitation artificial blood vessel Difficulty.The manufacture of artificial blood vessel, external research, the overwhelming majority is to take medical macromolecular materials to be woven.It is existing to use In the various high polymer materials of clinical vascular, two classes can be divided into, a class is synthetic material, such as terylene, expanded polytetrafluoroethyl-ne Alkene, polyurethane, PGA, PHA class etc.；Another kind of is natural biologic material, such as collagen, hyaluronic acid, fibroin albumen, chitosan, thin Fungin etc..The heavy caliber artificial blood vessel of these materials synthesis has clinically achieved remarkable effect, and realizes business Industry.But in terms of small-caliber vascular of the bore less than 6mm is substituted, such as artery of extremity blood vessel, coronary artery are also present Many serious the problem of, including blood compatibility is poor, plugging rate is higher etc..Although natural macromolecular material is than artificial synthesized material Material has more advantages, still, and small-caliber vascular prepared by current natural macromolecular material still has low intensity, elasticity The problems such as low, poor compatibility, antibiotic property are poor.
The content of the invention
It is an object of the invention to provide a kind of preparation method of fiber artificial's blood vessel.
To achieve these goals, the invention provides a kind of preparation method of fiber artificial's blood vessel, comprise the following steps：
Step 1, collagen is dissolved in mol ratio 1:In 2-3 hexafluoroisopropanol and the mixed solution of ethanol, quality is made Percentage concentration is 15-30% collagen solution；
Step 2, by polyester fiber add n- methyl pyrrolidones in, in 35-45 DEG C stir 10-14 hours, quality percentage is made Concentration is 20-40% polyester fiber solution；
Step 3, collagen solution and polyester fiber solution blending be subjected to electrostatic spinning, form fiber non-woven membrane tube structure；
Step 4, fiber non-woven membrane tube is soaked in the aqueous solution of oxidized dextran and Nano Silver mixing 2-5 hours, handed over Connection processing, that is, be made a kind of fiber artificial's blood vessel.
In the step 1, the mass percentage concentration of collagen solution is 20-25%.
In the step 1, collagen is pig source or fish source collagen albumen.
In the step 2, the mass percentage concentration of polyester fiber solution is 30-35%.
In the step 4, the mass percentage concentration of oxidized dextran in the aqueous solution of oxidized dextran and Nano Silver mixing For 10-15%, the mass percentage concentration of Nano Silver is 5-10%.
Beneficial effect：Fiber artificial's blood vessel that the present invention is provided not only has good blood compatibility, and improves Excellent elasticity and antibacterial surface performance, so as to solve, artificial small-caliber vascular blood compatibility is poor, plugging rate is higher, bullet Property low problem, preparation method is simple, and cost is low, environmentally friendly, high financial profit.
