Description

A kind of biodegradable medical hemostatic paper and preparation method thereof
Technical field
This experiment invention is related to a kind of biodegradable medical hemostatic paper and preparation method thereof, belongs to bio-medical material neck Domain.
Background technology
The present invention relates to biological hemostatic patch a kind of degradable and with excellent hemostatic function.Specifically use After natural medical polymer crosslinking, it is freeze-dried, is crushed to, available for surgery and the local hemostasis of wounded patient.
There is very big requirement to local hemostasis in clinical and real life, timely hemostasis contributes to us to avoid carefully Bacterium, viral situations such as infecting.In Clinical Surgery, help to reduce patient's blood transfusion so as to reduce the chance of infection.It is clinical at present and There are some commercial prods to come into operation in real life.Some traditional hemostatic materials have more shortcoming, such as, it is fine Fibrillarin glue anastalsis is good, but it is obvious to configure complex and inflammation.Collagen sponges are made up of foreign protei, office Portion's inflammatory reaction is also particularly evident.Preferable hemostatic material should meet multinomial requirement:It is non-toxic to human body first, have no stimulation And good biocompatibility.There is good Bioabsorbable simultaneously, be easy to process, there is certain mechanical property.
Hydroxymethyl cellulose is that a kind of etherified reaction of cellulosic molecule introduces soluble derivative obtained from methylol. The introducing of methylol improves the water solubility of cellulosic molecule, while it has good film forming, biocompatibility, nontoxic nothing Evil, is widely used in field of medicaments.Gelatin is the high dimerization of the partially hydrolysed obtained high-molecular polypeptide of the collagen of animal Compound, collagen can typically extract from the skin of animal, bone, cartilage, ligament, sarolemma etc..Its gelation, retentiveness, film forming Property, biocompatibility are very excellent, have been widely used for the industries such as food, medical science, chemical industry.2015, Liu Yong et al. public affairs A kind of preparation method (patent No. of chitosan medical biological antibacterial dressing is opened:CN201310463753.1), shell is gathered first Sugar is dissolved in acid solution and carboxymethyl chitosan is dissolved in water and is configured to chitosan solution and carboxymethyl chitosan solution, adds penta 2 afterwards The aldehyde crosslinking agents such as aldehyde make each self-crosslinking of above-mentioned solution, and finally by coating, biocompatibility height is prepared in freeze-drying, can be with The medical dressing of effective bacteria growing inhibiting.But crosslinking agent uses the aldehyde crosslinking agents such as glutaraldehyde, there is certain toxicity to human body, Potential safety hazard be present, do not meet green theory.This patent uses oxidized sodium alginate, and sodium alginate is through sodium periodate oxidation Obtained oxidized sodium alginate can not only improve the solubility property of sodium alginate, the dialdehyde that simultaneous oxidation sodium alginate obtains afterwards Schiff reaction can occur with the amino on gelatin for base, chemical crosslinking structure be formed, so as to instead of formaldehyde, glutaraldehyde etc. Poisonous aldehyde crosslinking agent.
The present invention is appropriately crosslinked by above-mentioned substance.Enough gel strengths and suitable crosslink density ensure that the suction of finished product Water-based and mechanical strength.The use of Freeze Drying Technique ensure that the porous of gel.Hemostatic adhesive bandage is made after finished product processing and packing, With preferable mechanical strength.
The content of the invention
The purpose of the present invention is to obtain a kind of biodegradable aerogel dressing, at the same reach must intensity, With preferable water imbibition and water resistance, soak do not change its structure in deionized water, while there is hemostasia effect.Described Biodegradable hydrogel material, using partial oxidation sodium alginate/sodium alginate/glutin/hydroxymethyl cellulose as matrix.For reality Existing above-mentioned target, is adopted the following technical scheme that:
(1) prepared by partial oxidation sodium alginate.Sodium alginate is configured to 1wt%~5wt% solution, adds high iodine Sour sodium solid lucifuge reacts 24~48h, adds ethylene glycol, NaCl stops reaction, precipitating, the filtering drying at 30~60 DEG C;
(2) preparation of sodium alginate/hydroxymethyl cellulose/gelatin cross-blend solution:Weigh sodium alginate 1.0wt%~ 5.0wt%, gelatin 1.0wt%~5.0wt%, hydroxymethyl cellulose 1.0wt%~5.0wt%.Add in deionized water, magnetic force Stirring, dissolves at 20 DEG C~60 DEG C.
(3) toughener 1,2- propane diols and glycerine 6wt%~12wt% are weighed altogether.Add the solution that (2) have dissolved In, magnetic agitation, normal-temperature dissolution.
(4) the partial oxidation sodium alginate 0.5wt%~3wt% for weighing step (1) preparation adds step (3) described system In, magnetic agitation, until partial oxidation sodium alginate dissolves, filtering, eliminate bubble.Afterwards with calcium chloride weak solution spray 3~4 It is secondary, stand a period of time.
(5) uniform rubber cement is made in colloid made of above-mentioned steps in homogenizer.Mould is poured into, in -10 DEG C~-40 DEG C ice 6~24h of precooling in case.Is freeze-dried finally with appropriate pressure compaction into paper chip solid with freeze drier afterwards.Disappear Poison, packaging.As gained biological hemostatic patch.
Specifically, the molecular weight of sodium alginate is 20000~200000g/mol, and the molecular weight of hydroxymethyl cellulose is 20000~200000g/mol, gelatine molecular weight are 20000~200000g/mol.
Specifically, sodium alginate and oxidizing agent sodium periodate and mol ratio are 1:1~2.
Specifically, 1, the mass ratio of 2 propane diols and glycerine is 1:1~5.
Specifically, calcium chloride solution concentration is 1wt%~5wt%.
Specifically.It is -40 DEG C~80 DEG C, cooling time 12~48h that freeze drier, which freezes parameter, 1~10 × 10-3MBr。
