Abstract
The present invention relates to a physical antibacterial anti-sticking medical dressing stitched by five layers of functional layers. The first layer is an antibacterial anti-sticking layer; gauze is immersed in a biologic antimicrobial preparation with positive charges, and then is pressed and processed in high temperature; cationic base groups form positive electric fields on the surface of fibre; the electric fields and negative charges impact to destroy the cell walls of microorganisms. The gauze is immersed by an anti-sticking agent prepared from emulsified silicon oil and cationic surface active agents and is pressed and dried in high temperature for the second time; then, the surface tension of the gauze is reduced; macromolecule base groups on the surface of the gauze are arranged in a fixed direction to form a ventilation film layer. The second layer is a hydrophilic layer which is prepared from a hydrophilic non-woven fabric; the third layer is a macromolecule absorption layer; the fourth layer is an auxiliary layer, and the outermost layer is a hydrophobic layer. The present invention has the functions of preventing adhesion, resisting bacteria, ventilating, absorbing moisture and resisting infiltration, and is widely applied to the protection and treatment of various scalds and wounds.
Description
Technical field
The present invention relates to is material about medical nursing, the medical dressing of specifically antibiotic about having, antiseized, hydrophilic, hydrophobic function.
Background technology
Wound healing is the prerequisite of human body functional rehabilitation after the wound, and it is particularly important therefore to accelerate wound healing research, and wherein the development to Wound dressing is one of focus of medical research in recent years.Traditional wound surface nursing is a material with the absorbent carbasus mainly, is immersed in the disinfection medicine, to reach antibacterial effect.But because gauze and wound is bonding, chemicals also has side effect such as in various degree stimulation, allergy to wound simultaneously, and make wound destroy repeatedly, impaired, can not get for a long time healing, even superinfection.At present, medicinal dressing mainly adopts kpetrolatum gauze, saline wet gauze or adopts method such as not adhesive membrane isolation cannot not reaching stickingly the purpose of wound, but it is ventilative, moisture absorption, leakage performance are poor, still is unfavorable for wound healing.Though developed activated carbon fiber dressing, composite nano materials dressing in the recent period, these products all are added with various CBA, certain toxic and side effects is all arranged, and production cost are higher.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the physical antibacterial anti-sticking medical dressing of a kind of ventilative, moisture absorption, antiseep.
The technical solution adopted in the present invention is: physical antibacterial anti-sticking medical dressing of the present invention adopts multiple structure to combine, this dressing is sewed up by the multilamellar functional layer and is formed, ground floor is antibiotic adherent layer, this layer be with gauze by positively charged biological antibiotic preparation flood, pressure roller, high-temperature process, cation group forms positive electric field at fiber surface, breaks up bad microorganism wall mutually with the negative charge antibacterial; By adopting the antitack agent of preparing by emulsified silicone oil, cationic surfactant to gauze double-steeping, pressure roller, hyperthermia drying, reducing surface tension handles, the gauze surface macromolecule group aligns and forms one deck breathable films, the second layer is a hydrophilic layer, this layer is for adopting hydrophilic nonwoven fabrics, the 3rd layer is the macromolecule absorbed layer, and the 4th layer is auxiliary layer, and outermost layer is a hydrophobic layer.
Absorbed layer is that liquid absorption is the macromolecule imbibition material sodium acrylate polymer of 100 times of deadweights; Auxiliary layer adopts does not have the firefly non-woven cotton by the ethylene oxide sterilizing disinfectant; Hydrophobic layer adopts does not have the firefly hydrophobic nonwoven by the ethylene oxide sterilizing disinfectant.
Adopt the beneficial effect that the present invention reaches after the above technical scheme to be:
1, physical antibacterial: adopt the sterilization of just little electric charge physical sterilization method, chemical addition not, non-stimulated, do not have allergy, no Drug resistance, have no side effect, kill the wound antibacterial rapidly, prevent superinfection.
2, not sticking wound: adopt the method that reduces the gauze fiber tension, make gauze and wound not sticking, reduce the patient suffering, convenient nursing avoids the wound secondary impaired, promotes wound healing.
3, absorb rapidly: use jumbo macromolecular material to make, prevent that the wound hydrops from infecting, the cleaning wound surface keeps wound clean, dry and comfortable, reverse osmosis not.
4, natural material: select that the high-quality cotton yarn is special to process for use, safety and comfort, soft ventilative.
5, prevent seepage: in safety locking moisture, outermost layer adopts the hydrophobic, air-permeability material to make, and guarantees that medicated clothing and bedding cleaning are pollution-free.
The specific embodiment
Prepare positively charged antibacterial biological preparation and the antitack agent of making by emulsified silicone oil, cationic surfactant.
Antibiotic adherent layer: with the gauze layer of contact skin, absorbent carbasus was soaked 10～20 minutes through the antibacterial biological preparation, pressure roller is removed moisture content, and through 80 ℃～130 ℃ hyperthermia dryings 5～20 minutes, utilizing special antitack agent that gauze is reduced surface tension handles, cation group forms positive electric field in gauze surface, when the wound antibacterial touches gauze surface, electronegative antibacterial then is attracted the formation covalent bond structure, and then destroying the cell wall of antibacterial, it is deadly that the content of antibacterial is leaked, and constantly absorbs the microorganism of wound surface simultaneously and organize detritus, the promotion slough softens and separates, kill bacteria because antitack agent has netted breathability, is handled it after gauze surface rapidly, macromolecule group forms vertical arrangement, changed the gauze surface performance, and formed one deck breathable films thereon, its viscous force is reduced, reach the purpose not sticking with wound, it easily takes off power less than 0.3N.
Hydrophilic layer: adopt no firefly hydrophilic nonwoven fabrics layer, when wound fluid is too much, because its distinctive hydrophile function is passed to absorbed layer with its filtered liquid rapidly through oxirane disinfection.
Absorbed layer: adopt the macromolecule imbibition material sodium acrylate polymer of liquid absorption for 100 times of deadweights, a large amount of moisture content are delivered to high molecular ventilation space by hydrophilic layer, macromolecule after the imbibition expand into spherical rapidly, and form numerous triangle spaces, keep good permeability, make wound surface obtain the exchange of oxygen and carbon dioxide, the wound surface environment of statocyte.Macromolecular material after the imbibition slowly discharges aseptic moisture content again, and wound is played the gentle regulating action of balance.
Auxiliary layer: have softness, plastic and elastic non-woven cotton layer, it is comfortable that dressing and wound are coincide.
Hydrophobic layer: have ventilative and fluid-tight hydrophobic nonwoven layer, prevent that wound fluid from oozing out, guarantee medicated clothing, the bedding cleaning is pollution-free.
Five layer materials are carried out cutting, sewing according to specification requirement, then made and have antibiotic antiseized, high-hygroscopicity, permeability, hemostasis, analgesia, the medical dressing of multiple structure.
