Abstract
The utility model relates to a dressing plaster containing nano-silver functional hydrocolloid, which comprises a transparent layer, an absorption layer, an alginate layer, an antibacterial layer and an isolation layer which are combined from outside to inside, wherein a fixed adhesive layer is arranged on the outer side of the transparent layer and is connected with the isolation layer through the fixed adhesive layer, the absorption layer is arranged in the center of the transparent layer, the absorption layer is a hydrocolloid layer, the antibacterial layer is hydrocolloid, the hydrocolloid contains nano-silver powder, and the center of the antibacterial layer is in grid distribution. The dressing plaster containing nano silver functional hydrocolloid is designed, and an antibacterial layer and an alginate layer are added on the basis of the hydrocolloid dressing, so that the dressing plaster has an antibacterial effect on wounds, promotes granulation growth and accelerates wound healing.
Description
Technical Field
The utility model relates to the technical field of medical supplies, in particular to a dressing plaster containing nano-silver functional hydrocolloid.
Background
The skin is a barrier for maintaining the internal environment stability of the human body and preventing the invasion of microorganisms, the medical dressing can protect the human body from being greatly damaged under the condition that the normal physiological function of the skin is damaged, and a wound surface covering with excellent performance can temporarily play a part of the function of the skin barrier before the skin is rebuilt or recovered, thereby providing a favorable microenvironment for the healing of the wound surface.
However, for the new medical history and specific application of people, the existing dressing with single function only has the ability of keeping the wound moist, cannot meet the various requirements of complicated wounds, and is difficult to meet the requirements of accelerating healing and bacteriostasis of different wounds, so that a series of novel medical dressings with excellent performance need to be provided.
Disclosure of Invention
In order to overcome the defects of the background art, the utility model aims to design the dressing plaster containing the nano-silver functional hydrocolloid, and an antibacterial layer and an alginate layer are added on the basis of the hydrocolloid dressing, so that the dressing plaster has an antibacterial effect on wounds, promotes granulation growth and accelerates wound healing.
The technical scheme adopted by the utility model is as follows: the utility model provides a dressing subsides that contain nanometer silver function hydrocolloid, includes stratum lucidum, absorbed layer, alginate layer, antibacterial layer and the isolation layer of outside-in combination, the outside of stratum lucidum is equipped with decides the glue film and is connected with the isolation layer through deciding the glue film, the central authorities of stratum lucidum are located to the absorbed layer, the absorbed layer is the hydrocolloid layer, antibacterial layer is formed by hydrocolloid and the mixing of nanometer silver powder, and antibacterial layer central authorities are the net and distribute.
Preferably, the one side of absorbed layer towards the isolation layer is equipped with the recess, alginate layer passes through the recess to be fixed in the absorbed layer, and alginate layer be fixed in the absorbed layer with between the antibacterial layer.
Preferably, the periphery of the antibacterial layer has a pore structure, and the pore diameter of the antibacterial layer is 0.3-5 μm.
Preferably, the alginate layer is calcium alginate fibers.
Preferably, the transparent layer is a PU film, and the isolation layer is release paper.
Compared with the prior art, the utility model has the beneficial effects that:
1. the antibacterial layer of laminating skin makes dressing subsides not adherent wound when changing dressings have antibacterial effect, improves the wound restoration quality.
2. The fiber of calcium alginate salt is added between the antibacterial layer and the absorption layer to release blood coagulation factors, promote granulation growth and accelerate wound healing.
3. The center of the bacteriostatic layer is in grid distribution, and the periphery of the bacteriostatic layer is in a pore structure, so that the absorption layer can absorb seepage, and the requirement of wet healing of the wound surface is met.
The embodiments of the present invention will be further described with reference to the accompanying drawings.

fig. 2 is a front view of the bacteriostatic layer 4 of the utility model;
Detailed Description
As shown in fig. 1 and 2, a dressing subsides that contain nanometer silver function hydrocolloid, including the stratum lucidum 1, absorbed layer 2, alginate layer 3, antibacterial layer 4 and the isolation layer 5 of outside-in combination, the outside of stratum lucidum 1 is equipped with decides the glue film 11 and is connected with isolation layer 5 through deciding the glue film 11, absorbed layer 2 locates the central authorities of stratum lucidum 1, absorbed layer 2 is the hydrocolloid layer, antibacterial layer 4 is formed by hydrocolloid and the mixing of nanometer silver powder, and antibacterial layer 4 central authorities are net distribution 41. One side of the absorption layer 2 towards the isolation layer 5 is provided with a groove 21, the alginate layer 3 is fixed in the absorption layer 2 through the groove 21, and the alginate layer 3 is fixed in the absorption layer 2 and between the antibacterial layers 4. The periphery of the antibacterial layer 4 is a pore structure 42, and the pore diameter is 0.3-5 μm. The alginate layer 3 is calcium alginate fiber. The transparent layer 1 is a PU film, and the isolation layer 5 is release paper.
When the dressing is applied to a wound, the antibacterial layer 4 is attached to the skin, the hydrocolloid component has the function of preventing wound adhesion, and meanwhile, the nano-silver powder in the hydrocolloid can effectively inhibit the growth of germs such as staphylococcus aureus, bacillus subtilis, candida albicans and the like, so that the requirements of various wound recovery such as burn, pressure sore and the like are met, and the wound recovery quality is improved; the alginate layer 3 contacts the wound through the holes of the grid distribution 41 of the antibacterial layer 4, and blood coagulation factors are released through the calcium alginate fibers to promote granulation growth; the exudate generated during wound healing is absorbed by the absorption layer 2 through the fine pore structure 42 of the antibacterial layer 4 and the calcium alginate fiber, thereby promoting wound healing.
The skilled person should understand that: although the utility model has been described in terms of the above specific embodiments, the inventive concept is not limited thereto and any modification applying the inventive concept is intended to be included within the scope of the patent claims.
