Abstract
The invention discloses a medical anti-microbial silver-plated dressing and a preparation method thereof. The preparation method of the medical anti-microbial silver-plated dressing includes steps of mixing calcium alginate fibers and cellulose fibers to prepare a dressing substrate and preparing a silver-particle plated layer on the surface of the dressing substrate by means of vacuum sputtering. The medical anti-microbial silver-plated dressing has broad-spectrum anti-microbial performance, is simple and easy in preparation method and low in cost.
Description
Technical field
The present invention relates to a kind of antibacterial silver-plating medical dressing and preparation method thereof.
Background technology
Medical dressing is skin injury that causes because of wound or disease in order to assisting therapy and disease such as fester; Particularly play good effect the long-term bedfast patient of nursing; Along with countries in the world population occurs to aging direction development trend; People's overnutrition and the corresponding disease brought in addition grow with each passing day to the demand of medical dressing.The effect of medical dressing mainly is to play to isolate human body skin damnification place and periphery environment, thereby avoids cutaneous lesion to receive the bacterium in the environment and cause infection.Simultaneously, medical dressing is also tackled the body fluid that oozes out because of skin injury and is had adsorptive power, to guarantee the drying of wound.Medical dressing and antibacterial medical dressing that present medical dressing comprises common medical dressing, has the high-absorbable ability, common medical dressing are that adopting through the skimming treatment cotton fibre is the material of main part formation; High general calcium alginate fiber and the cellulosic fibre blending composition that adopt of medical dressing that absorb with high water-retaining capacity; Antibacterial medical dressing is on the basis of above-mentioned two kinds of medical dressing, adds antimicrobial component and makes this medical dressing obtain antibacterial ability.The antibiotic method of bibliographical information comprises at present: organic antibacterial agent is immersed with the medical dressing for preparing in (1), has acquired antibacterial effect; (2) be to utilize nano silver particles, combine with medical dressing that play antibacterial effect, medical dressing is sneaked into antibacterial fiber in (3), acquires antibacterial effect through tackiness agent or other modes.Usually the antibacterial fiber that is adopted is a silver plated fiber.
There is problem targetedly in most of organic antibacterial agent kind, for the various bacteria population, use many antiseptic-germicide kinds, and it combines the complete processing complicacy with medical dressing, and utilization ratio is lower; Though nano-silver ionic has broad spectrum antibacterial, its processing difficulties, cost is higher.Silver-plated antibacterial fiber all has better anti-bacterial effect, can be after medical dressing carries out blending processing jointly, production technique is simple, but owing to can only adopt blending technology, so will reach antibacterial effect, the large usage quantity of silver plated fiber often.See only need have antibacterial effect and get final product with the auxiliary material surface of skin exposure from medical dressing anti-microbial effect mechanism.
Summary of the invention
The purpose of this invention is to provide a kind of antibacterial silver-plating medical dressing and preparation method thereof.
Antibacterial silver-plating medical dressing provided by the present invention is to prepare according to the method that comprises the steps: calcium alginate fiber and cellulosic fibre are mixed with the dressing base material; Adopt vacuum sputtering to prepare silver particles coating, obtain the antibacterial silver-plating medical dressing at said dressing substrate surface.
Concrete preparation method comprises the steps:
1) calcium alginate fiber and cellulosic fibre are prepared formation dressing base material by a certain percentage;
2) adopt aqueous sodium hydroxide solution, water, absolute ethyl alcohol to wash the removal finish successively said dressing base material, dehydration is inserted after the drying and is carried out silver-platedly in the vacuum sputtering device, obtains said antibacterial silver-plating medical dressing.
Said method also comprises obtaining the step that the antibacterial silver-plating medical dressing is cut, sterilizes, packed.
Wherein, the mass ratio of calcium alginate fiber and cellulosic fibre can be 10 in the step 1): 90-90: 10.Used cellulosic fibre is selected from any one or a few in cotton fibre, flaxen fiber and the viscose fiber.
Said dressing base material specifically can prepare by following three kinds of methods:
1) mix, divide comb, acupuncture to be prepared from alginate calcium bulk fibre and Mierocrystalline cellulose bulk fibre.
2) with the alginate calcium bulk fibre after minute combing into net, carry out composite acupuncture with the Mierocrystalline cellulose spunlace non-woven cloth and be prepared from.
3) with the alginate calcium bulk fibre after minute combing into net, carry out composite acupuncture with the Mierocrystalline cellulose woven fabrics and be prepared from.
Step 2) vacuum sputtering described in specifically can be magnetron sputtering method and/or radio frequency sputtering method.
Wherein, the sputtering target material that is adopted is argent and/or silver alloys; Sputter gas is a pure argon; In sputter procedure, substrate (being the dressing base material) temperature is a room temperature, target temperature≤80 ℃, and the base vacuum degree is less than (2-6) * 10
-4Pa; Operating pressure during sputter is 0.1-5Pa, and sputtering power is 30-50W, and sputtering time is no less than 1min; Keeping the distance between substrate and the target during sputter is 30mm-170mm.
Above-mentioned silver alloys as sputtering target material specifically can be yellow gold, and wherein silver content is no less than 50%.
The thickness of silvering can be controlled through the control sputtering time among the present invention, and general thickness is 10nm-100nm.
Beneficial effect of the present invention:
The present invention is mixed with medical dressing surface sputtering one deck nanometer silver through the method for vacuum sputtering at calcium alginate fiber and cellulosic fibre; When the body fluid that guarantees skin injury place exosmosed has the good adsorption effect, has good broad-spectrum antimicrobial effect.Because nano silver plating only is in the medical dressing surface, can directly act on skin injury place, compared with prior art antimicrobial efficiency and the utilization ratio that improves silver can be gone up largely, thereby the consumption of silver can be reduced significantly, reduce cost.
