Description
Technical field
This utility model belongs to medical dressing field, and in particular to a kind of sustained-release antibacterial dressing.
Background technology
Bacterial cellulose (BC) is a kind of cellulose by Microbe synthesis, with the structure similar to plant cellulose,
But it does not contain lignin and hemicellulose, specific retention is high, with hyperfine three-dimensional net structure.Due to its good biocompatibility,
The environmental benefits of moistening can be provided in wound healing, had broad application prospects at aspects such as wound dressing, beautifying skins.But
Bacterial cellulose itself does not have antibacterial activity, can not effectively prevent wound infection for wound dressing.
Nanometer silver is a kind of very strong inorganic antiseptic of antibiotic property, with broad spectrum antibacterial.Using nanometer silver as antibacterial
Fiber dressing, typically using physics sprinkling by the way of, as silver particles are only in fiber surface, once dressing absorption wound exudate
Afterwards, silver particles are come off into the factor such as gel or softening, it is impossible to ensure that wound dressing sustained release goes out enough due to surface moisture absorption
The antibacterial of amount, it is impossible to meet the demand of chronic wounds.
Current antimicrobial product, major part are that alginic acid salt, shitosan class, polyurethane foam class product or silver ion class are produced
Product, generally existing antibacterial effect is poor, healing cycle length, undesirable haemostatic effect, easy adhesion the shortcomings of.Chronic wounds can not be met
The demand of nursing.
Utility model content
The purpose of this utility model is to meet chronic wounds to the sustained anti-microbial of dressing, high liquid-absorbing and promoting wound
The demand of the features such as mouth healing, there is provided a kind of antibacterial action is strong, antibacterial lasting, high liquid-absorbing, can stop blooding and promote wound healing,
When wound exudate is more, can the leakage of anti-impervious liquid sustained-release antibacterial dressing.
The technical solution of the utility model is as follows：
A kind of sustained-release antibacterial dressing, from the side for contacting with wound surface, successively including antibiotic layer, liquid-adsorption layer and adhered layer,
And tight bond；Bacterial cellulose layer of the described antibiotic layer for loading nano silvery, described liquid-adsorption layer are shitosan and alginic acid

Preferably, the annular diversion leak-proof embossing ditch is around antibiotic layer surrounding.
Further, the leakproof thickeies the edge that flanging is arranged at liquid-adsorption layer.
Further, the annular diversion leak-proof embossing ditch quantity is no less than 1.
Preferably, the Bacterial cellulose layer of described loading nano silvery is obtained by chemical impregnation mode, and described is negative
A diameter of 10nm ~ 20nm of the nanometer silver on the Bacterial cellulose layer of carrying nano silver, the nanometer silver and the loading nano silvery
Bacterial cellulose layer mass ratio be 1:1001-1:101.
Further, the thickness of described antibiotic layer is 1.0 mm ~ 2.0mm, and the grammes per square metre of antibiotic layer is 80g/m2~100g/
m2。
Further, the thickness of described liquid-adsorption layer is 2.0 mm ~ 4.0mm, and the grammes per square metre of liquid-adsorption layer is 150g/m2~
180g/m2。
Preferably, it is 3mm ~ 5mm that described leakproof thickeies the width of flanging.
Preferably, the size for being smaller in size than liquid-adsorption layer of the antibiotic layer, liquid-adsorption layer are completely covered antibiotic layer；The imbibition
The size for being smaller in size than adhered layer of layer, adhered layer are completely covered liquid-adsorption layer.
Further, described adhered layer is the medical non-woven fabric adhesive tape for being coated with pressure sensitive adhesive.
The beneficial effects of the utility model are：
（1）Bacterial cellulose layer of the antibiotic layer for loading nano silvery, the hyperfine three-dimensional net structure of Bacterial cellulose can
Slow releasing function is played to nanometer silver, the anti-biotic material being compounded to form combines the excellent biocompatibility of Bacterial cellulose and nanometer
The characteristics of broad spectrum antibacterial of silver, so as to play the strong antibacterial action of lasting stability to wound, while have good biofacies concurrently
Capacitive and moisture retention, keep wound moist environment, promote wound healing.
（2）Liquid-adsorption layer is the composite non woven layer of cloth of shitosan and alginate, with very strong imbibition ability, the chi of antibiotic layer
The very little size less than liquid-adsorption layer, the compound nonwoven cloth edge that liquid-adsorption layer is contacted with antibiotic layer can absorb unnecessary wound in a large number and ooze
Liquid, contributes to slow releasing function of the Bacterial cellulose to nanometer silver in antibiotic layer, so as to play the strong antibacterial of lasting stability to wound
Effect, the synergism of antibiotic layer and liquid-adsorption layer can either durable antibiotic, the moist environment for keeping wound can be reached again, promoted
Wound healing, and dressing adhesion wound can be prevented.
（3）In liquid-adsorption layer, the calcium ion of alginate release, plays anastalsis to wound, effectively facilitates wound healing.
（4）Annular diversion leak-proof embossing ditch is set on liquid-adsorption layer and leakproof thickeies flanging, liquid-adsorption layer absorb sepage compared with
When many, can effectively be such that sepage is passed in annular diversion leak-proof embossing ditch rapidly, the lateral leakage protection effect of flanging be thickeied with reference to leakproof, will
Sepage is locked in non-woven fabrics, effectively the vertical absorption of guiding sepage, it is to avoid sepage horizontal proliferation is to periphery.
（5）Adhered layer is the medical non-woven fabric adhesive tape for being coated with pressure sensitive adhesive, and with very strong moisture-penetrable ventilated property, liquid-adsorption layer is inhaled
The wound exudate for receiving locking can pass through this layer of evaporation, provides the healing environment of moistening to wound surface, further promotes the healing of wound.
