Description
Technical field
This utility model belongs to medical dressing field, in particular to a kind of sustained anti-microbial alginate dressing.
Background technology
Along with the increase of China's population aging and chronic disease, the patient of chronic wounds increases year by year.According to national survey, chronic wounds carries out the 1.5%-3.0% that hospitalization person accounts for inpatients in surgical department sum, and based on traumatic ulcer, pressure ulcer and diabetic foot ulcer, the annual expense for chronic wound care in the whole world is up to 15,000,000,000 dollars.Based on current research, traditional Dry Therapy by wound wet union theoretical substitute, the various dressing developed based on moist theory are widely used at present in the clinical practice of chronic wound care.
In prior art, the overwhelming majority is all adopt silver ion, nanometer silver as antibacterial, and it exists the risk of silver ion deposition.In addition, using argent or nanometer silver as the fiber dressing of antibacterial because silver particles is only at fiber surface, once after dressing absorbs wound exudate, these silver particles may due to surperficial moisture absorption, becomes gel or the factor such as softening and comes off.Thus cannot ensure that wound dressing sustained release goes out the antibacterial of q.s, the sick human needs of chronic wounds can not be met.
Utility model content
The purpose of this utility model is to meet the demand of medical dressing goods to high-absorbable, sustained anti-microbial and promotion chronic wound care performance, provides the sustained anti-microbial alginate wound dressing of a kind of energy high-selenium corn wound fluid, sustainable release antibiotic substance and accelerating wound healing.
The technical solution of the utility model is as follows:
A kind of sustained anti-microbial alginate dressing; from bottom to top be made up of adhered layer, alginate sponges layer, active antibacterial layer and protective layer successively; and tight bond; described active antibacterial layer is made up of vinal layer and bioactivity glass; described vinal layer is by the multi-void fiber layer of vinal lack of alignment, in the surface that described bioactivity glass is dispersed in vinal layer and hole.
Preferably, described alginate sponges layer is made up of alginic acid zinc calcium salt, is loose porous sponge structure.
Preferably, described active antibacterial layer and alginate sponges layer are bondd by electrospinning device.
Preferably, the glass-loaded amount of degradable biological of described active antibacterial layer is 0.01wt%-1wt%, and described bioactivity glass particle diameter is 500nm ~ 1um.
Preferably, described bioactivity glass is the wherein one in silicate bioactivity glass, borate biological activity glass or phosphate bioactivity glass.
Preferably, the surface area of described alginate sponges layer is equal with the surface area of active antibacterial layer and form dressing layer, the surface area of described adhered layer is greater than the surface area of dressing layer, the one side that described adhered layer contacts with dressing layer and be not coated with medical pressure-sensitive adhesive by the part that dressing covers.
Preferably, described protective layer is divided into two pages, and juxtaposition covers above dressing layer, and extends to two ends, until cover adhered layer two ends.
Preferably, described protective layer is release paper.
Preferably, described adhered layer is transparent polyurethane film.
The beneficial effects of the utility model are: (1) this utility model possesses high-absorbable performance: first active antibacterial layer contacts wound, vinal has good absorbent, the concrete dynamic modulus shape of vinal layer, is made wound fluid easily be flowed into by the hole between fiber and has stronger absorption sepage ability alginate sponges layer; (2) this utility model possesses sustained anti-microbial performance: during active antibacterial layer contact wound, the bioactivity glass on vinal surface first with Wound contact, along with vinal imbibe, bioactivity glass in vinal hole is extruded out, and sustained release is to wound location, and bioactivity glass is aobvious alkalescence, be partially formed alkaline environment, can effectively in and the acid exudate of wound surface, restrain secondary infection, reach the effect of sustained anti-microbial; (3) this utility model possesses promotion chronic wound care performance: bioactivity glass is initiatively induced epithelial cell proliferation, breaks up, divided a word with a hyphen at the end of a line, and vinal and alginate sponges layer are the effect that wound keeps moist environment, make wound quickly-healing in moist environment; (4) alginate sponges layer is prepared from by alginic acid zinc calcium salt, and its structure is loose porous in sponge structure, in use, the sodium ion of the calcium that can simultaneously discharge, zinc ion and wound carries out ion exchange, form Sodium Alginate Hydrogel Films body and siphon away a large amount of wound exudate, for wound surface provides a moistening environment, facilitate the healing of wound, its absorb transudate ability strong, there is stronger lock outlet capacity; (5) calcium of dressing release, zinc ion play the effect of hemostasis and the effective healing promoting wound to wound; (6) protective layer is divided into two pages, can tear protective layer off easily during use, brings convenience for using; (7) transparent adhered layer can observe the absorption sepage situation of alginate sponges layer in use procedure; (8) adhered layer utilizes the medical pressure-sensitive adhesive of edge coating to be pasted onto on skin, makes its not landing for fixing dressing.
