Description
Technical field
The invention belongs to biological medicine Material Field, be specifically related to a kind of absorbability starch hemostatic powder and preparation method thereof.
Background technology
War wound, emergency care of trauma and surgical operation all can be formed hemorrhage, this problem needs solution badly, normal human is respectively provided with hemostatic function, slowly a small amount of hemorrhage self function can be relied on to stop blooding, but, the disguised oozing phenomenon body broken for hemorrhage, the internal organs of human body artery in various sudden accidents etc. can not stop blooding voluntarily, can not only lean on common tourniquet bandage hemostasis by compression, if patient's severe loss of blood, it is possible to shock, even entail dangers to life and health can be caused.Effective Hemostasis conventional at present is the resorbable material hemostasis of employing biocompatibility, provides a kind of safe and effective in surgical operation, first aid etc. are stopped blooding, and easy to use, hemostatic material with low cost is particularly important.
At present, the hemostatic material used clinically mainly has Fibrin Glue, collagen protein, gelfoam and cellulose hemostatic material, these materials all achieve good effect in zoopery and clinical practice, but also all come with some shortcomings: its raw material sources of collagen are in animal tissue, it it is foreign protein, rejection easily occurs, there is potential sensitization；Gelatin infiltration rate is slow, general more than 4 weeks, can increase the infection risk of wound；Cellulose family, human body lacks makes its enzyme degraded, and degradation time is long, it is possible to can bring the side effect such as infection to patient.
Starch is plant polysaccharide, its good biocompatibility, nontoxic, non-stimulated, not easily cause the anaphylaxis of body, monosaccharide can be degraded to by the amylase in body fluid in vivo, degradation in vivo absorbs.Carboxyethyl starch is a kind of modified starch, and nontoxic non-stimulated, do not cause inflammation reaction, is the material of a kind of good biocompatibility, has strong water absorption and water-retaining property.Starch hemostatic material representative at present is Arista styptic powder produced in USA, although its haemostatic effect is good, but it adopts epichlorohydrin cross-linked, there is genotoxic potential, and expensive, limits its application.
Summary of the invention
In order to solve the deficiencies in the prior art, the present invention provides a kind of absorbability starch hemostatic powder, this styptic powder has efficient anastalsis, good biocompatibility, safety non-toxic, technique simple possible, can be done directly on generally hemorrhage, Hemorrhage in Deep and the unapproachable position of operation technique hemorrhage, easy to use, and provide the preparation method and application of this styptic powder.
A kind of absorbability starch hemostatic powder, its main component is plant ative starch, carboxyethyl starch, and the weight ratio of described plant ative starch and described carboxyethyl starch is (1-50): (50-1).
Further, described plant ative starch is 1:50 or 1:1 or 1:2 or 50:1 with the weight ratio of described carboxyethyl starch.
Further, described absorbability starch hemostatic powder be described plant ative starch and described carboxyethyl starch generation at pH9-10, through Span 80, Tween 80 and vegetable oil emulsion dispersion under 45-70 DEG C of condition, and cross-link through sodium trimetaphosphate, ethyl acetate extracting separatory, absolute ethanol washing, oven drying, prepare after sterilizing.
Correspondingly, present invention also offers a kind of method preparing above-mentioned absorbability starch hemostatic powder, comprise the steps: soluble in water to plant ative starch and carboxyethyl starch blending, disperse through emulsifier, cross-linking agents, extractant extracting, washing, dry, sterilizing, thus obtaining the product absorbability starch hemostatic powder.
Further, described by soluble in water to plant ative starch and carboxyethyl starch blending, disperse through emulsifier, cross-linking agents, extractant extracting, washing, dry, the step of sterilizing, thus obtaining the product absorbability starch hemostatic powder, particularly as follows:
1) produce mixing starch suspension: by weight for (1-50): (50-1) weighs a certain amount of plant ative starch and carboxyethyl starch, is dissolved in the distilled water of 20-40 times, stirs, regulate pH to 9-10 with sodium hydroxide；
2) mixing starch emulsion is produced: weigh a certain amount of Span 80 for 1:1 by weight and Tween 80 makes blended emulsifier, mix with the vegetable oil dispersion of certain volume again, 10-30min is stirred under 45-70 DEG C of water bath with thermostatic control, making emulsifying dispersant, the mixing starch suspension then produced in step 1) adds wherein, stirs 10-30min, the envelope-bulk to weight ratio of vegetable oil and mixing starch is 15-100:1, the weight ratio of ml/g, blended emulsifier and mixing starch is 0.5-2.5:1, g/g；
3) cross-linking reaction: weigh a certain amount of sodium trimetaphosphate and be dissolved in distilled water, be subsequently adding step 2) in preparation mixing starch emulsion in, stirring reaction 2-8h, wherein, the weight ratio of sodium trimetaphosphate and mixing starch is 0.01-0.2:1, g/g；
4) extracting extracts: by the step 3) mixed solution stratification through cross-linking reaction, abandon supernatant, the ethyl acetate solution of 5-10 times of volume is added in lower floor's milky white liquid, after stirring, stratification, takes off layer milky white liquid and adds the absolute ethanol washing of 2-5 times of volume, stratification after stirring, abandoning supernatant, lower floor's milky white liquid vacuum is drained, and obtains solid particle；
5) styptic powder is prepared: be dissolved in the distilled water of 3-5 times of volume by the powder that step 4) prepares, magnetic agitation, stratification again, abandon supernatant, take off a layer milky white liquid, repeated washing 3-5 time, places in thermostatic drying chamber dry by the milky white liquid that finally obtains, and sterilizing, thus obtaining the product is to this starch hemostatic powder.
Especially, the plant amylum described in described step 1) includes potato starch, corn starch, sweet potato starch, one or more in wheaten starch.
Especially, described step 2) described in vegetable oil be bean plant oil.
Product of the present invention adopts good biocompatibility, the starch of safety non-toxic is that raw material prepares, bleeding part can be directly acted on, absorb rapidly the moisture in blood, reduce blood flowing speed, erythrocyte and PC increase, blood self-solidifying, play the effect of hemostasis by compression after material imbibition simultaneously.
Product preparation process of the present invention is simple, with low cost, can be used for various operating generally hemorrhage, Hemorrhage in Deep and the unapproachable position of operation technique is hemorrhage, easy to use.
