Abstract
The present invention relates to a preparation method of medical spongiosus styptic material, which is characterized by that it uses BG polysaccharide and makes it dissolve in water to obtain aqueous solution, and adopts low-temp. and vacuum drying process to obtain the invented product. Said invention possesses the advantages of simple process, convenient use, good styptic effect, and said invented styptic material can be extensively used in medical and bio-medical engineering field.
Description
The present invention relates to the preparation method of medical material, particularly relate to a kind of preparation method of spongy hemostatic material.
In the past, medical hemostatic material is that without extracting from the Pseudobulbus Bletillae (Rhizoma Bletillae) tuber, impurities is more the direct grind into powder of Chinese medicine the orchid family Pseudobulbus Bletillae (Rhizoma Bletillae) plant dry product, and working substance content is low, uses inconvenience, up to this point, does not still have spongy hemostatic material.
The objective of the invention is to remedy above-mentioned weak point of the prior art, and provide a kind of technology uncomplicated, easy to use, the preparation method of the spongy hemostatic material that effect is more excellent.
Purpose of the present invention can reach by following measure: the preparation method of spongy hemostatic material is that BG polysaccharide (chemical analysis is the polymer that mannose and glucose are formed) is water-soluble, by weight percentage, the concentration of aqueous solution of BG polysaccharide is 1～3%, freezing at-40～-60 ℃, under this low temperature and 5～15mmHg, carry out vacuum drying 8～10 hours, and promptly got spongy hemostatic material.
In the application while of the present invention, applied for another patent of invention again, denomination of invention is " a kind of extracting method of BG polysaccharide as hemostatic material ", discloses the extracting method of BG polysaccharide in this application in detail.
The present invention has following advantage compared to existing technology: because BG polysaccharide raw material is to extract from Chinese medicine orchid dry product, this sugar impurity is few, working substance content height, after low temperature and application of vacuum, be spongy material, shorten clotting time, hemostasis efficient height strengthens at bleeding tissue position and adhesion polarization and pull-out capacity, reduces the immunogenicity to tissue, promote wound healing effect and anti-tumor function, this material should be processed into various forms, as thin film, and fiber, bar, rod and porous spongy thing, easy to use, have broad application prospects.
With regard to an embodiment, the present invention is further specified below.
Embodiment 1:
In a container, get 2 gram BG polysaccharide, be dissolved in the 98 gram water, make concentration 2% aqueous solution,-50 ℃ of freezings, carried out vacuum drying under the 10mmHg 9 hours, promptly get spongy hemostatic material, this material is used for medical science and biomedical engineering, and can make goods such as hemostasis tooth plug with this material.
Claims (1)
1, a kind of preparation method of spongy hemostatic material, it is characterized in that: the BG polysaccharide is water-soluble, and by weight percentage, the concentration of aqueous solution of BG polysaccharide is 1～3%,-40～-60 ℃ freezing, under this low temperature and 5～15mmHg, carried out vacuum drying 8～10 hours.
