Description
Technical field
This utility model belongs to compound water congealing sebific duct field, particularly a kind of poroelasticity polyvinyl alcohol/Nano bacteria cellulose compound water congealing sebific duct.
Background technology
The support prepared of synthetic material is cause angiocarpy bracket to apply failed key factor with not mating of autologous tissue compliance.Research and development need emphasis to consider when preparing tissue engineering bracket and tissue substitute product with the biomaterial being replaced tissue mechanical similar mechanical.On the other hand, the artificial blood vessel prepared by polyester (PET), expanded PTFE (ePTFE) applied clinically at present easily forms thrombosis when replacing for small-bore (<6mm) blood vessel due to inner wall coarse thus leads to grave consequences.
Nano bacteria cellulose (Bacterial nano-cellulose, BNC) be by a kind of nano-cellulose of micro-organisms, there is high-crystallinity, high retentiveness, high Young's modulus, high-purity, the features such as good biocompatibility, have wide application in fields such as food, papermaking, medical materials.The tubular material prepared by Nano bacteria cellulose is in recent years because of the nanofiber network structure of its uniqueness and good biocompatibility, have a good application prospect in small-caliber artificial blood vessel and intravascular tissue engineering support, receive the extensive concern of researcher.The at present existing many sections of reports Nano bacteria cellulose water-setting sebific duct that utilized diverse ways to prepare, and its mechanical mechanics property, biocompatibility etc. are studied.But this tubular material prepared by nano-cellulose does not have elasticity, limit its application as medical material.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of poroelasticity polyvinyl alcohol/Nano bacteria cellulose compound water congealing sebific duct, this compound water congealing sebific duct mechanical mechanics property is controlled, the demand of Various Tissues recovery support can be met, the nanofiber network structure of compound water congealing sebific duct is conducive to sticking and propagation of cell, and its loose structure be interconnected is conducive to the transmission of nutrient substance and growing into of cell.
A kind of poroelasticity polyvinyl alcohol/Nano bacteria cellulose compound water congealing sebific duct of the present utility model, comprises top layer and nexine, and the surface on described top layer is level and smooth shape, and described nexine is nanofiber network structure.
Nexine is the loose structure with connection.
Described composite aquogel bore 3 ~ 6mm, external diameter 4 ~ 10mm, long 50 ~ 60mm.
This utility model is the elasticity and the compliance that improve Nano bacteria cellulose pipe, by polyvinyl alcohol [Poly (Vinyl Alcohol), PVA] and Nano bacteria cellulose compound, prepare a kind of poroelasticity polyvinyl alcohol/Nano bacteria cellulose compound water congealing sebific duct.
The loose structure that composite aquogel pipe prepared by the method has excellent nanofiber network structure and is interconnected, excellent mechanical mechanics property, can realize, to the regulation and control of composite aquogel pore footpath, porosity and mechanical mechanics property, meeting the requirement of the multiple tubular tissue recovery support such as blood vessel, nerve well by controlling preparation process parameter.
beneficial effect
This utility model mechanical mechanics property is controlled, the demand of Various Tissues recovery support can be met, the nanofiber network structure of compound water congealing sebific duct is conducive to sticking and propagation of cell, its loose structure be interconnected is conducive to the transmission of nutrient substance and growing into of cell, at vascular repair support, in CO2 laser weld support, there is good application prospect.
