Description
Technical field
The present invention relates to medical material fields, and in particular to the preparation and application of medical haemostatic material, more particularly to one
Kind medical haemostatic material and application process that quickly injection forms a film.
Background technology
Haemophilia is not only second main cause dead in wounded patient, and it is to cause blood coagulation to bleed profusely with wound
The Major Risk Factors of obstacle, bleeding late also play an important role in morbidity and mortality, continue low blood pressure, sepsis
Disease, a large amount of red blood cells and plasma products seepage flow can lead to a variety of organ failures.Therefore for surgeon, hemostasis is clinical
Important challenge in work realizes that quick-acting haemostatic powder direct result is to improve hemodynamic stability and avoid the potential of blood transfusion
Negative effect.
Earliest, hemostasis is mainly using wrapping, but haemostatic effect is poor, with the development of science and technology, gradually occur with
The hemostatic material for wrapping up cooperation, becomes the main path of hemostasis.Therefore the non-absorbability topical hemostatic agent such as bone wax is largely answered
For clinic, and it is applied to surgical operation always for quite a long time and stops blooding, but since this kind of hemostatic material histocompatbility is poor,
Easily cause foreign body reaction, it is difficult to degrade, cause the infection of art area and other complication inevitable.Novel hemostatic material, it is such as fine
Element, chitin, polyvinyl alcohol, collagen, chitosan etc. are tieed up, has obtained preferable application in terms of hemostasis.
Chinese invention patent application number 201110442310.5 discloses a kind of high-efficiency silicon oxide hemostasis material, hemostatic material
Material is that silica has adsorbed a large amount of calcium ion, and the adsorption activation material of blood plasma；The invention reaction condition is mild, grasps
Make simple and easy to do, raw material is cheap and easy to get；Obtained hemostatic material product haemostatic effect is fabulous, is used as and is stopped by using silica
Blood material can significantly improve the biocompatibility of hemostatic material, present applying in vivo for silica hemostatic material
Good prospect；The distinctive porous of Metaporous silicon dioxide material can contribute to controlling for wound with adsorption antibacterial element and anodyne etc.
It treats, the material of the invention can be used for the hemostasis of different medical applications, combine, can be made into other medical materials, medical instrument
Adhesive bandage, infusion paste, adhesive dressing, tablet and capsule core material, operation packet, first-aid dressing etc..
Chinese invention patent application number 201410748904.2 discloses a kind of absorbable hemostasia membrane material, main component
Including starch, carboxymethyl cellulose, gelatin, the weight ratio of starch, carboxymethyl cellulose and gelatin is（1~4）:（1~2）:（1~
3）；The invention also discloses a kind of preparation method of absorbable hemostasia membrane material, by preparation by way of blended under agitation
Starch solution, cmc soln, gelatin solution are uniformly mixed, and membrane material is made；Hemostasis membrane material prepared by the invention
With good biocompatibility, absorbable and degradable, hemostasis while, has effects that prevent adhesion again.In addition, the invention system
Compound hemostatic material raw material sources it is extensive, safe and non-toxic, preparation process is simple.
Chinese invention patent application number 201610110213.9 discloses a kind of complex polysaccharide hemostasis film and its preparation side
Method, component and each component mass fraction are as follows：10 ~ 20 parts of chitosan, 2 ~ 8 parts of glucose, 3 ~ 6 parts of methylcellulose, gelatin 1 ~ 5
Part, 4 ~ 7 parts of pectin, 4 ~ 7 parts of sodium trimetaphosphate, 8 ~ 20 parts of polyalcohol, 5 ~ 8 parts of agar, 2 ~ 8 parts of sorbic acid, sodium alginate 5 ~ 10
Part, 3 ~ 6 parts of Radix Notoginseng, 1 ~ 3 part of fumaric acid sodium, 2 ~ 5 parts of garden burnet.The invention polysaccharide is that matrix is added hemostatic compositions appropriate and helped
Agent prepares film-like hemostatic material, and compared with conventional pulvis or spray, membranaceous hemostatic material can synchronize in terms of two to be stopped
Blood, bleeding early stage, membrane body are similar to tourniquet, can quick-acting haemostatic powder, while hemostatic compositions in film synchronize hemostasis, double-hemostasis function work(
Can, the bleeding time is substantially reduced, haemostatic effect is apparent, and easy to use.
Chinese invention patent application number 201610574391.7 discloses a kind of medical hemostatic closed material and composition, and one
Kind medical toughness closes hemostatic material, by with one of A-R-A or B-R1-B structures polymerization or be condensed or two kinds
The mixture of substances of structure is condensed or is polymerized.The medical toughness closing hemostatic material and composition of the present invention, by connecing branch
The reactive group that polymerization or condensation reaction interconnect can occur, form film forming or the material with liquid absorption capacity, make
Used time, can be administered position will form a film or water-absorbent material by energy-rich bond it is compound by form high tenacity membrane material or water-absorption material
Material, to achieve the effect that preferably to close wound or hemostasis, prevents occult blood or secondary bleeding possibility.
According to above-mentioned, the hemostatic material in existing scheme mainly achievees the purpose that hemostasis using quick adsorption blood, by
It is influenced by blood pressure in wounds streamed blood, typically injection is bled, and acute bleeding excess can be caused by depending merely on absorption blood, or even jeopardize life
Life, thus assist finger-press method, pressure dressing, cushioning song limb method and hemostasis with tourniquet etc., however hemostasis by compression require compared with
Height, wrapping is extremely inconvenient, and wrapping, which kicks the beam, is difficult to achieve the purpose that hemostasis, and wrapping is overweight to cause secondary damage.
Invention content
For current the problem of being difficult to effectively stop blooding using wider quick adsorption hemostatic material, and it is aided with hemostasis by compression
When exist require it is high, it is difficult to effective hemostasis by compression, the defects of wrapping hemostasis is difficult to operate, easily cause secondary damage, the present invention carries
