Abstract
The utility model relates to a medical hydrogel wound dressing with a drainage function. The medical hydrogel wound dressing with the drainage function comprises a release film layer and a drainage device. More than two penetrating holes are formed in the drainage device. When the medical hydrogel wound dressing with the drainage function is used, hydrops of a wound surface with a large amount of exudation, especially a burn or scald wound surface in a large-exudation period is drained out through the penetrating holes in the medical hydrogel wound dressing, the problem that the hydrops is caused by low-speed of absorption of a hydrogel wound dressing is solved, the risk of wound infection is reduced, meanwhile, the problems that a traditional dressing sticks to a wound surface when dressing change is carried out, so that pain is caused to a patient, and secondary damage is caused to wound tissue are solved, the healing speed is increased, and healing quality is improved.
Description
Technical field
This utility model relates to a kind of medical hydrogel wound dressing that possesses the drain function, especially relates to a kind of medical hydrogel wound dressing that is applicable to the wound surface that transudate is more.
Background technology
The more wound surface of the transudate especially height of empyrosis wound surface oozes out the phase, needing in time derives transudate, can increase infection risk as can not in time deriving, and traditional dressing mostly is gauze, absorbent cotton pad, the dressing of foam class, occur dressing and wound surface adhesion when changing dressings easily, cause secondary damage.Hydrogel is kind of an emerging wound surface nursing medical dressing, is foundation with the wet union theory, prevents that moisture and body fluid are excessively lost; Resist bacterial invasion, protect from infection; With wound surface fit good, and not with the wound surface adhesion, having avoided more, change dressings brings secondary damage; Saturating wet, ventilative and make wound surface be in moist environment; Good biocompatibility has the effect that promotes wound healing, becomes the first-selection of novel wound surface nursing dressing.Hydrogel can slowly absorb sepage, though hydrogel can slowly absorb sepage, oozes out the phase for height, and the speed of absorbed sepage is slower, can not fast hydrops be discharged.
The utility model content
For the sepage of wound surface in height oozes out the phase discharged fast, and prevent from the secondary damage of changing dressings wound surface being caused from reducing patient's pain.Technical problem to be solved in the utility model provides a kind of medical hydrogel wound dressing that possesses the drain function.This dressing can be discharged sepage fast from wound surface, reduce hydrops and produce, and then reduce the risk of traumatic infection, and the hydrogel excellent biocompatibility makes that patient is painless to change dressings simultaneously; With the wound surface adhesion, do not avoid wound surface to be destroyed by secondary; Improve healing quality.
The technical scheme that this utility model solves the problems of the technologies described above is as follows: a kind of medical hydrogel wound dressing that possesses the drain function, comprise release rete and drainage system, and described drainage system is provided with plural penetrability hole.
The beneficial effects of the utility model are: when using this utility model, ooze out the phase for the more wound surface of the transudate especially height of empyrosis wound surface, fast hydrops is discharged by penetrability hole in the dressing, it is slow and cause the problem of hydrops to have solved the aerogel dressing rate of adsorption, reduce the risk of traumatic infection, overcome traditional dressing simultaneously when changing dressings and the wound surface adhesion damages to bring painful of patient and to the secondary that wound tissue carries out; Accelerate healing rate, improved more back quality.
On the basis of technique scheme, this utility model can also be done following improvement.
Further, described drainage system comprises hydrogel layer and layer of support material, described release rete is positioned at described hydrogel layer top, described layer of support material is positioned at the bottom of described hydrogel layer, described release rete is connected with described layer of support material by described hydrogel layer, and described penetrability hole is located on the described hydrogel layer.
Further, described layer of support material and hydrogel layer connected mode comprise: described layer of support material is attached to described hydrogel layer surface or is combined in hydrogel layer inside.
Further, described penetrability hole is of a size of 5～30 millimeters.
Further, can be circular, square, oval and other can form the Any shape of penetrability hole.
Further, the shape of described release rete is corresponding with the shape of described hydrogel layer, and its surface area is greater than the surface area of described hydrogel layer.
Further, the edge that exceeds described hydrogel layer, the edge of described release rete is of a size of 0～30 millimeter.
Further, the thickness of described hydrogel layer is 2～5 millimeters.
Further, the thickness of described layer of support material is 0.3～15 millimeter.
Further, the thickness of described release rete is 0.012～0.12 millimeter.
