Abstract
The utility model relates to a curling wound dressing with high moisture absorption performance and high wet strength. The curling wound dressing comprises a bottom layer made of non-sol fibers, and a lint layer made of sol fibers and can curl naturally into a cylindrical shape, wherein the bottom layer is inside and the lint layer is outside. The curling wound dressing can be used for nursing a chronic ulcer wound in a cave shape or a concave shape, such as a vein blood stasis ulcer, a pressure ulcer and a diabetic foot ulcer, and other chronic ulcer wounds.
Description
Technical field
This utility model relates to a kind of curling wound dressing of high moisture absorption high wet strength.
Background technology
As everyone knows, all wish to use the Morden wound dressing with high moisture absorption when nursing ulcer wound, particularly have the fiber wound dressing of colloidal sol performance such as calcium alginate wound dressing, Chitosan in Wound Dressing, modified cellulose wound dressing etc.The characteristics of these dressing are high moisture absorption and humectant, thereby can provide a relatively moistening environment to wound healing.But the wet strength that a remarkable shortcoming of this class dressing is exactly dressing is lower.The low wound dressing of wet strength cracky and strengthen the difficulty of wound care work in the removal process more likely causes wound or peripheral skin infection.
General wound can produce a large amount of transudates in agglutination, some wounds can ooze out the transudate up to 50ml in 24 hours.Therefore the colloidal sol fiber wound dressing that needs clinically to have high-hygroscopicity absorbs these transudates, but also wishes the wet strength that way can improve dressing, and making dressing still have some strength after absorption is saturated can remove by full wafer.Take the calcium alginate wound dressing as example, the absorbable transudate of this dressing can reach 20 times more than of own wt.Modal larger wound dressing (weight of 10cm * 20cm) is generally 2-3g, after fully absorbing, and this dressing 60g or more that can weigh.This reaches with regard to the wet strength that needs wound dressing
Or more than, wound dressing may cause because wet strength is low and damaged the change of dressing difficulty when preventing from changing dressings.
Yet, be more the wound dressing that demand has high-hygroscopicity and high wet strength performance simultaneously in the market.
