Abstract
The invention particularly relates to a medical hemostatic material and a preparation method thereof, and belongs to the technical field of medical materials. The medical hemostatic material is prepared from a set of mixed materials and non-woven fabrics, wherein the mixed materials comprise, by mass, 60-75 parts of chitosan fiber, 6-15 parts of keratin, 10-25 parts of sodium carboxymethylcellulose and 5-10 parts of polyvinyl alcohol. The medical hemostatic material has the advantages of being fast in hemostasis, excellent in mechanical property, good in biocompatibility and the like.
Description
Technical field
The invention belongs to medical material tech field, be specifically related to a kind of hemostatic material in medical use and preparation method thereof.
Background technology
Usually, in the normal situation of blood of human body self coagulation function, general tissue injury can self-regeneration, and the hemorrhage or venous hemorrhage of epidermis can self-solidifying.But, when arterial hemorrhage, hemorrhage compared with large vein, more serious tissue injury or most surgical procedures, blood cannot reach the function of self-protection in time from coalescence, as taken measures not in time, will cause serious hemorrhage, excessive often threat to life of losing blood.Especially, afield, in the various situation such as field burst accident, earthquake class natural disaster, surgical operation, use hemostatic material fast and effectively particularly important.
In recent years, develop increasing hemostatic material both at home and abroad, existing hemostasia products is mainly divided into two large classes according to hemostatic mechanism, one class is based on the normal clotting mechanism of blood, as gel sthptic sponge product, dry haemproteins product etc., another kind of, be the clotting mechanism not relying on normal blood, the hemostasia products that the material as being representative with chitosan and molecular sieve is made.The range of application of a rear series products is wider, and particularly when the wounded has blood coagulation disorders or use anticoagulant, effect is more more superior.
Usually need to possess following characteristic as excellent hemostatic material in medical use: 1) there is biocompatibility, and to organism avirulence; 2) infection of wound can not be increased, can not can't bring out the reaction of inflammation by contaminated wound; 3) bleeding stopping period is short, haemostatic effect good; 4) mechanical property reaches the premium properties of hemostatic material in medical use; 5) good with the adhesiveness of tissue, good with the anastomose property in wound, site, wound surface place; 6) answer no antigen, degraded and absorbed in vivo can select degradable absorbing material or Nondegradable material according to different hemostasis objects; 7) a large amount of heats is not produced while stopping blooding, to prevent tissue, neural burning; 8) manufacturing cost is as far as possible cheap etc.
In prior art, study the hemostatic material obtaining many types both at home and abroad and developed many hemostasia products, but its mechanical property, anthemorrhagic speed, also do not reach very desirable haemostatic effect with the attaching performance of the tissue of bleeding site or the combination property such as anastomose property, absorbent, and function singleness, all more or less there is such or such deficiency or defect.
