Abstract
The utility model discloses a hydrogel medical dressing, comprising a basal layer, a chitosan hydorgel layer, a calcium alginate short fiber layer and an insulation film layer; the chitosan hydrogel layer is arranged on the basal layer and is provided with the calcium alginate short fiber layer; and the insulation film layer is arranged on the calcium alginate short fiber layer. The hydorgel medical dressing has excellent strength and tenacity, and has high transparency and excellent capacity of absorbing exudate of a wound; the hydrogel medical dressing does not need to be added with any enhancing layers such as chemical crosslinking agent or initiator, medical adhesive, fiber fabric or non-woven fabric, is reasonable in design, simple in structure and favorable for the absorption of the wound, facilitates the healing of the wound, has the effects such as better hemostasis, anti-inflammation, pain-killing and small scar after recovery, and can be widely used for the hemostasis and bandage materials of trauma such as blood stopping, operative incision, burning and scalding in the operation process.
Description
Technical field
This utility model belongs to field of medical article technology, relates in particular to a kind of hydrogel medical dressing.
Background technology
Before the human record of relevant wound healing first can be traced back to thousands of years, people just find that wound surface exposed healing effect after covering is good at that time, various types of dressing appearred for a long time, as animal skin, Mel, plant leaf, even clay, incense ashes are also as wound-surface cover, but practicality is the strongest, the power of influence maximum, the application time is the longest, still occupy at present the gauze class dressing that is referred to as traditional dressing of very big market share, this class dressing is generally by Cotton Gossypii, lint and linen process, its advantage is: certain absorbability is arranged, make simple, low price, reusable, shortcoming is: can't keep the moistening wound healing that causes of wound surface to postpone, thereby the dressing fiber easily causes foreign body reaction influence healing, easy damaged new life's tissue when changing dressings, pathogen is the dressing by being soaked into easily, the workload of changing dressings is big etc., along with the reach of science, people recognize and use dressing not only for flap coverage, also wound healing must can be helped, simultaneously because materialogy and technological progress, make the functional and practicality of dressing that breakthrough variation take place in recent years, the medical high molecular aquagel wound dressing is a kind of novel dressing that development in recent years is got up, can be widely used in all kinds of ulcer wounds, the wound that wound causes, burn and scald wound and chemicals erosion wound, become normal gauze, emulsion state is raised the succedaneum that wound surface is handled dressing, dressing is applicable to that also old people's ulcer hinders face and handle, along with China and the arrival in European and American areas aged tendency of population epoch, this class dressing will have more and more broader market prospect.
The utility model content
The purpose of this utility model is to provide a kind of hydrogel medical dressing, is intended to solve aerogel dressing at the application problem of patient's wound.
This utility model is achieved in that a kind of hydrogel medical dressing, and described hydrogel medical dressing comprises: basal layer, aquagel layer, calcium alginate short fiber layers, insulating thin layer;
Described basal layer is provided with described aquagel layer, and described calcium alginate short fiber layers is arranged on described aquagel layer, and described calcium alginate short fiber layers is provided with described insulating thin layer.
Further, described aquagel layer and calcium alginate short fiber layers constitute network structure.
Further, described insulating thin layer is non-infiltration insulation film.
Hydrogel medical dressing of the present utility model has excellent intensity and toughness, also has the ability of the absorption wound fluid of high transparent and excellence.Aerogel dressing of the present utility model need not add any chemical cross-linking agent or initiator, medical adhesive, fabric or or enhancement Layer such as non-woven fabrics.A kind of hydrogel chitosan medical dressing of the present utility model is reasonable in design, simple in structure, be conducive to wound absorbs, promotes wound healing, has effects such as hemostasis preferably, anti-inflammatory analgetic, more the back cicatrix is little.Can be widely used in hemostasis and the wrapper material of wounds such as the hemostasis of operation process and operative incision, burn, scald.
