Abstract
A medical dressing material for stopping hemorrhage, preventing infection of wound and promoting healing is proportionally prepared from chitin fibers and silk protein fibers through mixing, adding deionized water, stirring to become pulp, adding water- soluble high-molecular material, fluffing, homogenizing, wet shaping, and baking.
Description
Technical field
The present invention relates to the preparation method of a kind of chitin and fibroin fiber blend wet nonwoven fabrics medical dressing.
Background technology
Chitin is as a kind of natural macromolecular material, without any side effects to human body, also having broad-spectrum antiseptic, infection and anastalsis and promote wound to heal again, strengthen physiological activities such as body immunity, is the suitable functional natural macromolecular material of safety and sucrose.
In developed country such as American-European-Japanese, chitin material and derivant thereof are widely used in the medical sanitary field.As the operation suture thread that du pont company is produced, need not remove after the recovery; U.S. Pat 6197322 is used non-weaving cloth the solution coatings that contains chitin/chitosan, non-weaving cloth after the coating is through containing the solution-treated of alkali, the chitosan that is present in the non-weaving cloth can slowly be absorbed by bioengineered tissue, thereby promotes the cell growth.
Domestic have chitin is prepared into aqueous solution or saliva stream film forming, or preparation becomes powder, gel or spun-laced nonwoven fabric etc. and is used for medical wound.But certain weak point is all arranged, the use inconvenience that has, the effective component content that has is lower, what have is soft inadequately, can not be close to wound surface, also have ventilative, moisture retention is not enough etc., has influenced result of use.
Fibroin albumen and human body have the good generation compatibility, occur as the many forms with fibroin membrane of medical material." Chinese shaping burns unit " 14 interim reports in 1998 are treated fibroin membrane on nothing infection and aseptic wound surface." textile journal " calendar year 2001 3 is interim makes the medicine fibroin membrane with antibacterials and fibroin albumen, and uses on Infected Burn Wound Surface." textile journal " 2005 5 phases have been set forth the physicochemical property of fibroin/chitosan mixed film in " fibroin blend film " literary composition, and point out that fibroin/chitosan semi-intercrossing network type film has the possibility as " artificial tendon ".But fibroin protein film and complex thereof be because its bacteria resistance function is relatively poor, and ventilative, moisture retention is not strong, and cost of manufacture is higher, has influenced its application.
Summary of the invention
At the deficiency of existing chitin and fibroin albumen medical material, the object of the present invention is to provide the preparation method of a kind of chitin and fibroin fiber blend wet nonwoven fabrics medical dressing.
The technical solution adopted for the present invention to solve the technical problems is:
Carry out proportioning for 2～10 parts with 10～20 parts of chitin fibers and fibroin fiber, add 200～1000 parts of deionized waters, fiber is pulled an oar after blend, add 0.01～1 part of water-soluble high-molecular material again, continue to discongest, homogenate, in the wet-web former online molding of manufacturing paper with pulp, oven dry is prepared into the lamellar non-woven fabric medical dressing.
Described water soluble polymer is sodium alginate, carboxymethyl cellulose, polyacrylic acid, polyacrylamide, Polyethylene Glycol, polyvinyl alcohol, gelatin, xanthan gum, quaternary polyamines or polyethylene glycol oxide.
The technology that described employing wet-laying method prepares non-woven fabrics is 10～20 meters/minute of the speed of a motor vehicle of manufacturing paper with pulp.
The present invention arrive the product of moisture content＜10%.Section, packing, cobalt-60 radiosterilization.
The present invention compares with background technology, the beneficial effect that has is: product softness of the present invention, can be close to wound surface, air permeable humidity retaining is good, has the ability of stronger hemostasis and absorptive tissue transudate, can control wound infection effectively, promote wound healing, few with the wound surface adhesion, alleviate the misery of changing dressings, and reduced the generation of medical waste.Product processes is simple and easy, quick, has reduced production cost, and product is easy to use.
