Description
Technical field:
The present invention relates to hemostasis gel technical fields, and in particular to a kind of to utilize microcrystalline cellulose graft modification abortive calfskin glue
The hemostasis gel of fibrinogen preparation.
Background technique:
Often the bleeding profusely along with the surface of a wound in surgery and trauma operation, so that patient be made to face great life
Danger, therefore prepare the research hotspot that quickly and effectively hemostatic material is used as always medical field.Traditional hemostatic material exists
The shortcomings that not portable and disinfection saves, and stop blooding and almost lean on mechanism, haemostatic effect is bad.In recent years, people develop
Biological absorbable hemostatic material, wherein Animal Skin Collagen sill is as a kind of good medical material of biological property, with human body
It is biodegradable and have no toxic side effect with good histocompatbility, while adherency, proliferation and the wound of cell can be promoted
It is compound;And by its distinctive microcellular structure and good adhesiveness, promotes the growth of biotic factor to spread, induce and promote
Into fibroblastic growth, to promote the healing of wound.
Currently, it is sour enzyme combination extraction method that universal Animal Skin Collagen, which extracts preparation method, main includes the pre- place of raw material
Reason, degreasing enzymolysis, digestion, are saltoutd, are centrifuged and purified, but there is gained collagen purity and low yield, at high cost etc.
Problem, and collagen can be made to reduce or lose biomechanical property because dealing with improperly in extraction process, stop to influence it
Blood effect.For this problem, our company starts with from the extracting method of collagen, and combines the modification to collagen is extracted
And the addition of auxiliary agent prepares hemostasis gel material, improves haemostatic effect, biocompatibility, biology drop on a low-cost basis
Solution property and safety in utilization.
Summary of the invention:
Technical problem to be solved by the present invention lies in providing, one kind is easy to use, haemostatic effect is good and has superior bio
The hemostasis gel of compatibility and biological degradability prepared using microcrystalline cellulose graft modification abortive calfskin collagenous fibres.
The following technical solution is employed for the technical problems to be solved by the invention to realize:
The hemostasis gel prepared using microcrystalline cellulose graft modification abortive calfskin collagenous fibres, is included the following steps:

Sodium mixed aqueous solution impregnates 10~15min, then uses sponge brush brushing surface 2~3 times under deionized water shower;
(2) preparation of collagenous fibres Extraction solvent: according to the ratio of 1.2~1.5:1 of molar ratio by Cyclopropyl Bromide and 2- pyrrole
Pyrrolidone is sufficiently mixed, prior to being ultrasonically treated 15~30min under supersonic frequency 40kHz, power 50W, then at microwave frequency
3~5min of microwave treatment under 2450MHz, power 700W is then heated to 30~60min of reflux state insulated and stirred, to be mixed
5-10 DEG C of deionized water of the weight such as addition, is sufficiently stirred rear stratification after solution naturally cools to 50-55 DEG C, phase of fetching water,
Up to Extraction solvent;
(3) preparation of collagenous fibres solution: the abortive calfskin after above-mentioned scrub is sent into freeze drier, dry to aqueous
Amount using onal machine is ground into the particle that granularity is 2-3mm after being 10-15%, adds in above-mentioned made Extraction solvent, sufficiently
10~15min is stood after dispersion, is transferred in ball mill after standing, is milled to fineness less than 50 μm, is then added pH=3's
Disodium hydrogen phosphate-citrate buffer solution utilizes the Surface Treatment with Plasma machine of working frequency 40Hz, power 600W after being sufficiently mixed
10~15s is handled to gained mixture, after treatment is transferred to 3~5h of standing in 0~5 DEG C of environment, polyacrylic acid is then added
And polyethylene glycol oxide, and it is heated to reflux state 15~30min of insulated and stirred, 270 meshes are finally crossed, gained filtrate is collagen
Fiber solution;
(4) microcrystalline cellulose, poly- second the preparation of modified collagen fiber solution: are added into above-mentioned made collagenous fibres solution
Glycol 6000 and L-Aspartic acid are sufficiently mixed, in 35~40 DEG C of 1~2h of sealing and standing after being uniformly dispersed then in Microwave Frequency
2~3min of microwave treatment under rate 2450MHz, power 700W, is sufficiently mixed again, and utilizes working frequency 40Hz, power 600W

Temperature, 10~15min of insulated and stirred is after temperature is down to 0~5 DEG C to get modified collagen fiber solution;
(5) preparation of hemostasis gel: into above-mentioned made modified collagen fiber solution be added polyglycolic acid, Polycarbophil,
Vitamin K and aminocaproic acid are distributed into mold after being sufficiently mixed uniformly, and utilize gamma-rays sterilization, are finally packaged
The cryo-conservation under the conditions of 0~5 DEG C afterwards.
The dosage mass ratio of sodium bicarbonate and sodium tripolyphosphate is 2~3:1 in the step (1).
Abortive calfskin, Extraction solvent, disodium hydrogen phosphate-citrate buffer solution, polyacrylic acid and polyoxygenated in the step (3)
10~15:40 of dosage mass ratio~50:0.5~1:0.5~1:0.5~1 of ethylene.
Polyacrylic acid passes through chemical modification, method of modifying are as follows: by polyacrylic acid and junket ammonia using preceding in the step (3)
Acid be added double weight part ethyl alcohol in, reflux state insulated and stirred 10min is heated to after being uniformly dispersed, add resveratrol and
Disodium ethylene diamine tetraacetate continues at insulated and stirred 30min under reflux state, after gained mixture naturally cools to 35-40 DEG C
It is transferred in 0-5 DEG C of environment immediately and stands 8h, be then fed into spray dryer, obtained solid is ground after drying is made powder.
The polyacrylic acid, tyrosine, resveratrol and disodium ethylene diamine tetraacetate dosage mass ratio be 10~15:1
~2:3~6:0.5~1.
The dosage matter of collagenous fibres solution, microcrystalline cellulose, Macrogol 6000 and L-Aspartic acid in the step (4)
Measure ratio 25~30:3~6:1~2:0.5~1.
The use of modified collagen fiber solution, polyglycolic acid, Polycarbophil, vitamin K and aminocaproic acid in the step (5)
Measure 25~30:2 of mass ratio~3:1~2:0.5~1:0.5~1.
The beneficial effects of the present invention are: the present invention purifies abortive calfskin as raw material can trace to the source, it is molten that extraction prepares collagenous fibres
Liquid, and the extracted collagenous fibres of microcrystalline cellulose graft modification are utilized, and be aided with a variety of auxiliary agents and hemostasis gel is made, it should be only
Blood clotting glue can directly overlie bleed site, play haemostatic effect, and stop blooding rapidly, promote wound while effectively reducing amount of bleeding
The reparation in face;There is excellent biocompatibility and biological degradability simultaneously, it is safe to use, without the secondary work of any poison after use
With.
