Abstract
The utility model relates to a physical antibacterial anti-sticking medical dressing, mainly stitched by five functional layers. The first layer is a physical antibacterial anti-sticking gauze layer which is tightly stuck on the wound, and the bottom of the layer is connected with a hydrophilic non-woven cloth layer. A high polymer absorption layer is provided between the hydrophilic non-woven cloth layer and a fourth auxiliary layer, and the outermost layer is a hydrophobic non-woven cloth layer. The dressing can effectively kill the bacteria of the wound and prevent the secondary infection of the wound. The utility model has the functions of sticking prevention, anti-bacteria, permeability, moisture-absorption and penetration-resistance. The physical antibacterial anti-sticking medical dressing can be widely applied to the nursing of various traumas of scald.
Description
Technical field
This utility model relates to a kind of medical nursing material, and specifically a kind of have a medical dressing antibiotic, antiseized, hydrophilic, hydrophobic function.
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, this utility model provides the physical antibacterial anti-sticking medical dressing of a kind of ventilative, moisture absorption, antiseep.
The technical scheme that this utility model adopted is: the dressing of this physical antibacterial anti-sticking medical adopts the multilamellar functional layer to sew up composition, ground floor is the antiseized gauze layer of physical antibacterial, this layer is earlier gauze to be flooded by positively charged biological antibiotic preparation, pressure roller, high-temperature process, cation group forms positive electric field at fiber surface, break up bad microorganism wall mutually with the negative charge antibacterial, then by adopting by emulsified silicone oil, the antitack agent of cationic surfactant preparation is to the gauze double-steeping, pressure roller, hyperthermia drying, reduce surface tension and handle, the gauze surface macromolecule group aligns and forms one deck breathable films; The second layer is a hydrophilic layer, and this layer adopts hydrophilic nonwoven fabrics; The 3rd layer is the macromolecule absorbed layer, adopts the macromolecule imbibition material sodium acrylate polymer of liquid absorption for 100 times of deadweights; The 4th layer is auxiliary layer, and this layer employing do not have the firefly non-woven cotton by the ethylene oxide sterilizing disinfectant; Outermost layer is a hydrophobic layer, and this layer employing do not have firefly coloured glaze water non-woven fabrics by the ethylene oxide sterilizing disinfectant.
Adopt the beneficial effect that this utility model reaches after the above technical scheme to be:
1, physical antibacterial: adopt the sterilization of just little electric charge physical sterilization method, non-stimulated, irritated, Drug resistance, toxic and side effects are killed the wound antibacterial rapidly, prevent superinfection.
2, not sticking wound: gauze adopts the method that reduces fiber tension, makes gauze and wound not sticking, reduces the patient suffering, and convenient nursing avoids the wound secondary impaired, promotes wound healing.
3, absorb rapidly: adopt jumbo macromolecular material, prevent that effectively 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.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among Fig. 1, the antiseized gauze layer 1 of physical antibacterial, hydrophilic nonwoven fabrics layer 2, macromolecule absorbed layer 3, auxiliary layer 4, hydrophobic nonwoven layer 5.
The specific embodiment
Antibiotic adherent layer: with the gauze layer of contact skin, absorbent carbasus was soaked 10～20 minutes through positively charged antibacterial biological preparation, pressure roller is removed moisture content, and through 80 ℃～130 ℃ hyperthermia dryings 5～20 minutes.The antitack agent that employing is made by emulsified silicone oil, cationic surfactant, gauze is reduced surface tension to be handled, cation group forms positive electric field in gauze surface, when the wound antibacterial touched gauze surface, electronegative antibacterial then was attracted the formation covalent bond structure, and then destroyed the cell wall of antibacterial, make the content of antibacterial leak deadly, constantly absorb the microorganism of wound surface simultaneously and organize detritus, the promotion slough softens and separates, rapidly kill bacteria.Because antitack agent has netted breathability, and it is handled after gauze surface, 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, when wound fluid is too much, rapidly its filtered liquid is passed to absorbed layer 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: employing has softness, the anti-cotton layer of plastic and elastic nothing, and it is comfortable that dressing and wound are coincide.
Hydrophobic layer: adopt to 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 according to specification requirement sew up and to form, then made and have antibiotic antiseized, high-hygroscopicity, permeability, hemostasis, analgesia, the medical dressing of multiple structure.
