The dressing of a kind of hydrogel antibacterial gauze
Technical field
This utility model belongs to medical dressing technical field, is specifically related to the dressing of a kind of hydrogel antibacterial gauze.
Background technology
The wound surface tissue of Human body package in air can cause infection, and cause other complication because of the invasion of the microorganism such as escherichia coli, staphylococcus aureus, breeding.The use of medical dressing, can stop microorganism to a great extent, dust enters wound tissue, be convenient to the nursing of wound, promotes wound healing.
Traditional gauze class dressing, is mainly made up through deep processing of cotton, numb material raw material, due to advantages such as processing technology are simple, cheap, easy to use, generally uses this type of dressing in the market.But normal gauze dressing is soft, toughness is poor, easy adhesion wound tissue, cause secondary mechanical to damage, and edge cotton fiber easily comes off, be bonded on wound when changing dressings, and is difficult to remove.In order to overcome problems, people have prepared kpetrolatum gauze, are convenient to the drain of wound tissue's transudate, can provide enough humidity, promote wound healing.But kpetrolatum gauze dressing breathability is poor, does not have antibiotic property, the infection of wound surface cannot be controlled preferably, and vaseline oil easily residues in and wound surface is difficult to cleaning.
Utility model content
Technical problem to be solved in the utility model is, for the deficiencies in the prior art, provide one to have potent antibacterial, prevent traumatic infection, wound fluid can be absorbed, prevent adhesion wound tissue, be applicable to the hydrogel antibacterial gauze dressing of various empyrosis wound surface nursing.
For solving the problems of the technologies described above; the technical scheme that this utility model adopts is: the dressing of described hydrogel antibacterial gauze is from bottom to top followed successively by supporting layer, hydrogel layer and protective layer composition, and described hydrogel layer contains Ag nano antibacterial agent or Ag-ZnO composite nano germicide.
Described supporting layer is the polyester fiber gauze be formed by weaving through volume mode.
Described protective layer is PE thin slice.
Described protective layer covers and wraps up the exposed parts of described hydrogel layer and supporting layer.
The coating weight of described hydrogel layer is 500 ~ 600g/m2.
The beneficial effects of the utility model are as follows:
1) hydrogel antibacterial gauze of the present utility model dressing selects polyester gauze as supporting layer, compared with traditional degreasing cotton gauze, there is good toughness, on-deformable advantage, be easy to the even spread of hydrogel layer, and the dressing of suitable size can be cut out according to the size of wound surface, easy to use.
2) hydrogel antibacterial gauze dressing hydrogel layer of the present utility model not exclusively fills the polyester yarn cloth mesh of supporting layer, can ensure that gauze dressing has good breathability, promotes the quickly-healing of wound surface.
3) hydrogel antibacterial gauze dressing hydrogel layer of the present utility model adds a certain amount of inorganic nano antiseptic, compared with traditional antibacterial, the advantage such as there is good heat stability, biocompatibility, never degenerate, zinc is also one of necessary trace element of human body simultaneously, this makes this dressing both effectively can control the infection of wound surface, can be again human body and trace element is provided, promote patient's early recovery.
This utility model structure is simple, and easy to use, good toughness, good permeability, stable performance, can promote the quickly-healing of wound surface preferably, is applicable to the nursing of various burn wound surface, alleviates the misery of sufferer.

Detailed description of the invention
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
As shown in Figure 1, the dressing of a kind of hydrogel antibacterial gauze, be from bottom to top followed successively by supporting layer 3, hydrogel layer 1 and protective layer 2 and form, described supporting layer 3 is the polyester fiber gauze be formed by weaving through volume mode, and described protective layer 2 is PE thin slice.This utility model selects the polyester fiber gauze be formed by weaving through volume mode, the gauze sound construction that this weaving mode is prepared, difficult deformation, and polyester fiber toughness is better, is easy to the even spread of hydrogel layer.
Preferably, described hydrogel layer 1 is containing Ag nano antibacterial agent or Ag-ZnO composite nano germicide, the zinc wherein contained in Ag-ZnO composite nano germicide is one of necessary trace element of human body, so both effectively can control the infection of wound surface, can be again human body and trace element is provided, effectively can promote the healing of wound surface.
Preferably, the coating weight of described hydrogel layer 1 is 500 ~ 600g/m
2, be more preferably 550g/m
2.
Specific embodiment described herein is only to design of the present utility model explanation for example.This utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
