Description
Technical field
The present invention relates to the preparation method of a kind of medical dressing.
Background technology
Medical aseptic dressing is mainly used in when human body suffers when epidermis, muscular tissue wound, to this must and
Shi Jinhang wrapping and treatment, and currently mainly use common dressing and be unfavorable for the healing of wound, and easily produce adhesion
Deng.
Bamboo fibre has the characteristics such as good breathability, moment water absorption, stronger wearability and good dyeability, tool
There are natural antibacterial, antibacterial, acaricide, deodorant and anti-ultraviolet function.
Chitosan is as a kind of natural macromolecular material, without any side effects to human body, and have Antibacterial activity,
Absorption and excretion heavy metal, the promotion function such as blood coagulation and wound healing, have the functional natural of immunoregulatory activity for a kind of
Macromolecular material.
Summary of the invention
Because the drawbacks described above of prior art, the technical problem to be solved is to provide a kind of chitosan and bamboo
The preparation method of fiber blend wet nonwoven fabrics medical dressing.
For achieving the above object, the invention provides a kind of chitosan and bamboo fibre is blended wet nonwoven fabrics medical dressing
Preparation method, chitosan with weight portion as 10-20 and the weight portion bamboo fibre as 2-10 carry out proportioning, add weight portion and are
The deionized water of 200-1000, blended rear making beating, add the water-soluble high-molecular material that weight portion is 0.01-1, after filtration
Remove the larger particles in mixed liquor, in order to molding, then by prepared mixed liquor by after spinneret orifice extrusion mixing liquid thread,
Again through 85-90 DEG C of coagulating bath, this mixed liquor thread is frozen into spun filament, spun filament is carried out drawing-off formation composite fibre long
Silk.This solidification temperature is conducive to the solidification of viscose glue stock solution, forms the structure of even compact, is also beneficial to form overall orientation degree
Height, crystallizes fairly perfect fiber；The too high or too low structure being all unfavorable for forming even compact of temperature (concentration).
Further, described water-soluble high-molecular material is sodium alginate, polyacrylamide, polyacrylic acid, polyvinyl pyrrole
One or more in alkanone, polyvinyl alcohol, polymaleic anhydride, polyquaternium, Polyethylene Glycol and shuttle cellulose.
Further, described its speed of manufacturing paper with pulp of technique using wet-laid method to prepare non-woven fabrics is 30-40 m/min
Clock.
Technique effect: the present invention can resist some antibacterials easily causing infection, it is to avoid wound suppuration, simultaneously for wound
The transudate in face has the strongest adsorption, can be the most antibacterial, antiinflammatory, promotes the healing of wound, and nontoxic, aseptic, becomes
This is cheap, easy to use.
Product is soft, can be close to wound surface, and air permeable humidity retaining is good, has stronger hemostasis and the energy of absorptive tissue transudate
Power, can efficiently control wound infection, and wound healing is few with wound surface adhesion, alleviates the misery changed dressings, and decreases medical treatment
The generation of rubbish.Product processes is simple, quick, reduces production cost, and product is easy to use.

It is sponge loose structure that chitosan prepared by the present invention and bamboo fibre are blended wet nonwoven fabrics medical dressing, average hole
Footpath is 100 microns, and mutually runs through, and is conducive to the ventilative and absorption of moisture.Other dressing in the prior art that compares,
Dressing of the present invention loose porous, hole is the most intensive and hole size uniform, and pore size is moderate, of the present invention applies
The water absorbing capacity of material is extremely strong, the absorbable liquid being equivalent to own wt 17 ~ 25 times.
The medical dressing that embodiment 1-7 prepares is carried out the detection of external moisture pick-up properties: weigh 8.3 g sodium chloride and
The anhydrous calcium chloride of 0.277 g, is dissolved in the distilled water of 1L and is configured to the solution A that British Pharmacopoeia specifies.Testing example 4,
During the pick up of dressing that 5,6 prepare, place 24 h after dressing is cut into 5 cm × 5 cm sizes respectively, make the regain of fiber
Reach balance.At this moment the initial mass measuring dressing is W.Weigh the solution A than dressing weight 40 times, respectively by solution and dressing pair
Should be placed in the culture dish of 2 a diameter of 9 cm, after placing 30 min at 37 DEG C, clamp one jiao of dressing at sky with tweezers
In, weigh the wet quality (W1) of dressing after hanging 30s.The pick up of unit mass dressing=(W1-W)/W (g/g), unit are
Pick up=4 (W1-W) g/100 cm2.Repeat above-mentioned experiment 3 times, seek its meansigma methods.
During test liquid distribution in fiber and between fiber, the dressing (quality is W1) after imbibition with gauze respectively
Packing together after being placed in dewaterer dehydration 15min, measuring the quality of dressing after being dehydrated is W2, and this quality is fiber itself
Dry mass and be absorbed into the summation of liquid quality of fibrous inside.Then the dressing after centrifuge dehydration in 105 DEG C of dry 4h, examination
The dry mass W3 of fiber is recorded after the most permanent quality of sample.W1-W2 is to absorb liquid between the fibers, and W2-W3 is to be absorbed into fibre
Liquid within Wei.(W1-W2)/W3 and (w2-w3)/w3 can calculate the dressing of every gram of dry mass respectively and absorb between fiber
Liquid with fibrous inside.
Experimental result: medical dressing being centrifuged dehydration and is finding after drying, dressing itself has good water suction
Property, in the moisture absorbed, most can be retained in fibrous inside, is difficult to be removed by centrifuge dehydration.
The preferred embodiment of the present invention described in detail above.Should be appreciated that those of ordinary skill in the art without
Need creative work just can make many modifications and variations according to the design of the present invention.Therefore, all technology in the art
Personnel are available by logical analysis, reasoning, or a limited experiment the most on the basis of existing technology
Technical scheme, all should be in the protection domain being defined in the patent claims.
