Background technology
In wound healing process, a physical barriers can be formed using medical dressing, prevent the entrance such as dust, bacterium
Wound is convenient for the nursing of wound, is necessary using dressing.Some existing medical dressing in the market, especially for middle heavy
The dressing of the exudative surface of a wound is spent, some cannot keep surface of a wound moistening, delay wound healing；Some wound bed fluid absorbabilities compared with
Difference causes the surface of a wound to impregnate；Some new granulation tissues easily grow into the mesh of dressing, and when dressing can cause pain；Some nonreactives
Bacterium acts on, easy infection.
In order to keep the moistening of the surface of a wound, the dressing using hydrogel as substrate is gradually appeared, hydrogel has unique three
Reticular structure is tieed up, effectively moisture can be locked wherein, so that the water content of hydrogel is up to 95% or more, and can slowly release
It discharges water point, keeps micro- wet environment of the surface of a wound, wound healing, and hydrogel is generally also provided with certain imbibition ability, energy
It is more cannot to meet the exudation of surface of a wound initial stage however, since the rate of liquid aspiration of Hydrogels dressing is relatively low for slow-absorbing wound exudate
The nursing stage, which greatly limits this kind of dressing in clinical use scope, occurs thus by hydrogel and imbibition material
Compound dressing, if Chinese patent CN205964286U discloses a kind of hydrogel foam dressing, by being set on hydrogel layer
Froth bed is set, the improvement result low to hydrogel rate of liquid aspiration is realized using froth bed, drainage can quickly be absorbed by obtaining one kind
The dressing of wound fluid.
But it usually also needs to prevent bacterium infection, traditional mode in wound healing process to be additional on wound
Using wound and drug is covered with dressing again after antibacterials, complexity is operated with, therefore gradually appeared and loaded antiseptic
In dressing, direct antibacterial action of the dressing to wound, such as above-mentioned hydrogel foam dressing are realized, it will usually in hydrogel layer
The antibacterial action that antiseptic ingredient realizes dressing is loaded, but there are antiseptics quickly and efficiently to be released from hydrogel
It puts, and can not really realize its antibacterial action, in order to overcome this defect, it will usually can be molten using wound fluid is encountered
The hydrogel material of solution releases antiseptic ingredient such as collagen hydrogels material during hydrogel material dissolves,
But the dressing of the traditional structure such as above-mentioned patent disclosure, when encountering the material that sepage can dissolve using collagen hydrogels etc.
When material, excessive defect after being dissolved there are hydrogel material.Therefore, it is necessary to be directed to existing aerogel dressing structure into traveling one
The improvement of step.
