Description
Technical field
This utility model relates to a kind of chitosan compound bandage, belongs to medical care articles for use.
Background technology
Bandage, is adhesive bandage again, as the term suggests having had wound just can stick, is a kind of surgical dressing conventional in our daily life.Existing bandage water absorption and aeration poor, be unfavorable for the drain of wound exudates and pus, the easy growth and breeding of antibacterial, wound healing is slow, pastes use for a long time, skin surface due to airtight and hydrops, cause skin surface to bleach, downright bad, scab.Therefore, the use of bandage is very restricted, and increasing people is when skin is hemorrhage by slightly scratching, and all no longer the common bandage of choice for use protects wound.So a kind of ventilative and good water absorption of research and development, has again good antibacterial, antibacterial, antiinflammatory, hemostatic function, can promote wound healing, promote tissue growth, reduces hope and demand that the bandage of cicatrization meets people.
The polysaccharide that chitosan is made up of aminoglucose and n acetylglucosamine n polymer, it can be deacetylated and obtain, also natural existence in certain micro-organisms and yeast by the chitosan moiety in carapace.The scientific basic that chitosan stops blooding, promotion wound healing, minimizing scar are formed with validity first reports for 1978; confirm that it is remarkably productive through long-term practice, and the chitosan acetate film of contact and protection wound have the advantages such as good oxygen permeability, strong absorptive and slow enzyme (lysozyme) degradability.
Utility model content
The purpose of this utility model is, provides a kind of chitosan compound bandage, to solve above-mentioned technical problem.
For solving the problem, the technical scheme that this utility model adopts is:
A kind of chitosan compound bandage, comprise and hemostasis is play to wound, promote wound healing, reduce the treatment block of scar formation effect, for carrying the base band for the treatment of block and treatment block being played to the mask paper of protective action, described base band is the spun-laced nonwoven fabric band that surface scribbles medical adhesive, and described treatment block is adhesively fixed at the middle part of base band by adhesive; Described mask paper bag draws together left mask paper and right mask paper; The inner of described left mask paper, right mask paper hides respectively to the right, left on treatment block, and it is mutually cross layered, the outer end of described left mask paper, right mask paper and marginal adhesion are fixed in the base band outside treatment block, and their stacked the inners that intersects are also adhered to one another; It is characterized in that: described treatment block comprises water accepting layer and chitosan dressing layer, described water accepting layer is arranged between base band and chitosan dressing layer; Described chitosan dressing layer is nonwoven fabric construct, is evenly distributed with several air-vents.
Beneficial effect: compared with prior art, chitosan dressing layer of the present utility model directly contacts wound, good hemostasis can be played, promote wound healing, reduce scar formation effect, the air-vent of chitosan dressing layer and the water accepting layer of short texture can ensure the high-permeability of moisture and air, tissue exudates is absorbed by water accepting layer through the air-vent of chitosan dressing layer, reach efficient absorbency, and the water accepting layer absorbing transudate is intercepted by chitosan dressing layer and wound and opens, avoid directly contacting with wound, reach the effect that reverse osmosis leaks, wound is avoided to occur turning white and the phenomenon of swelling.Therefore, this utility model have good permeability, absorbency high, can the advantage such as counnter attack seepage, antibacterial, wound healing promoting, the formation of minimizing scar.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
With reference to Fig. 1, chitosan compound bandage described in the utility model, comprise hemostasis play to wound, promote wound healing, reduce the treatment block of scar formation effect, for carry treatment block base band 1 and to the mask paper for the treatment of block and rise protective action.
Described base band 1 is the spun-laced nonwoven fabric band that surface scribbles medical adhesive, and described treatment block is adhesively fixed at the middle part of base band 1 by adhesive.Described mask paper bag draws together left mask paper 5 and right mask paper 6; The inner of described left mask paper 5, right mask paper 6 hides to the right, left respectively on treatment block, and mutually cross layered; The outer end of described left mask paper 5, right mask paper 6 and marginal adhesion are fixed in the base band 1 outside treatment block, and their stacked the inners that intersects are also adhered to one another.
Described treatment block comprises water accepting layer 2 and chitosan dressing layer 3, and described water accepting layer 2 is arranged between base band 1 and chitosan dressing layer 3; Described chitosan dressing layer 3 is nonwoven fabric construct, is evenly distributed with several air-vents 4.
