Abstract
The utility model relates to a dressing used for nursing the wound surfaces of various acute and chronic wounds and particularly provides a composite type hydrogel dressing. According to the technical scheme of the utility model, the composite type hydrogel dressing adopts a five-layer structure, wherein a hydrogel layer (2) and a non-woven cloth layer (3) are cross-linked to be combined together. One side of the non-woven cloth layer (3), which is not in contact with the hydrogel layer, is attached to a pregummed ventilated waterproof film (4). The outside of the ventilated waterproof film (4) is attached with a layer of support film (5). One side of the hydrogel layer (2), which is not in contact with the non-woven cloth layer (3), is covered by release paper or release film (1). The composite type hydrogel dressing can quickly absorb the exudate from a wound surface and is ventilated and waterproof. Meanwhile, the dressing is not bonded with the wound surface, so that the wound surface is prevented from dipping in excessive exudates. In addition, a slightly wet condition for promoting the healing of the wound is provided. The self-adhesive property of the dressing greatly facilitates the application of the dressing in clinical use.
Description
Technical field
This utility model relates to a kind of Wound care dressing that is applicable to various acute and chronic wounds, specifically a kind of composite water gel dressing.
Background technology
Hydrogels dressing has unique tridimensional network, can effectively moisture be locked in wherein, makes the water content of hydrogel can be up to more than 95%, and can slowly discharge moisture, keeps little wet environment of wound surface, wound healing.In addition, Hydrogels dressing also has certain imbibition ability usually, can slowly absorb wound exudate; yet; because the rate of liquid aspiration of Hydrogels dressing is lower, can not satisfy the wound surface initial stage oozes out the more nursing stage, and this has limited this class dressing greatly in the clinical scope of application.In addition, because Hydrogels dressing water content is higher, make it be difficult for being combined with the medical adhesive tape with pressure sensitive adhesive, this has increased the fussy degree of using.For overcoming the problems referred to above, the part hydrogel is prepared into compounded dressing for wound, and the composite water gel dressing is composited by several parts such as ventilated membrane, non-woven fabrics or fabric skeleton, hydrogel, adhesive usually.
Patent CN2383500Y discloses a kind of hydrogel compounded dressing for wound, it is the one side covering one deck gas permeable polymers film at hydrogel layer, between hydrogel layer and the gas permeable polymers film by the adhesion layer combination, the another side of hydrogel layer covers release paper or stripping film, and the patented product has the good transparency, high-hydroscopicity, breathability, poisture-penetrability but be waterproof.This patent has solved the self-adhesion problem of hydrogel,, its quick imbibition still is difficult to realize, although it has high-hydroscopicity, needs several hours even longer time realization but this high-hydroscopicity is common.
The utility model content
Technical problem to be solved in the utility model provides and a kind ofly can absorb fast wound fluid, air permeable waterproof, adhesion wound surface, comfortableness MULTILAYER COMPOSITE aerogel dressing strong, easy to use.
The technical scheme that this utility model solves the problems of the technologies described above is as follows: a kind of composite water gel dressing, and it adopts five-layer structure, is followed successively by release paper or mould release membrance 1, hydrogel layer 2, nonwoven layer 3, the pre-gelatinized ventilative film 4 that blocks water, support rete 5; Described hydrogel layer 2 combines by crosslinked with nonwoven layer 3, the one side that described nonwoven layer 3 does not contact with hydrogel sticks on the pre-gelatinized ventilative film 4 that blocks water, support the outer surface that rete 5 covers the ventilative film 4 that blocks water, the one side that described hydrogel layer does not contact with nonwoven layer covers release paper or mould release membrance 1.
The described pre-gelatinized ventilative film 4 that blocks water is pre-gelatinized medical polyurethane film.
Wherein, described hydrogel layer 2 is identical with the overall dimensions of nonwoven layer 3, and the described pre-gelatinized ventilative film 4 that blocks water is identical with the overall dimensions that supports rete 5 and release paper or mould release membrance 1; The overall dimensions of the described pre-gelatinized ventilative film 4 that blocks water is greater than the overall dimensions of hydrogel layer 2.
The thickness of hydrogel layer is 0.1mm～5mm.
The weight per unit area of described nonwoven layer (3) is than being 60g/m
2～200g/m
2
This MULTILAYER COMPOSITE aerogel dressing can be made into rectangle, square, circle, ellipse, H type or other arbitrary shape.
The beneficial effects of the utility model are: do not add poisonous and harmful substance at the hydrogel that adopts this mode to prepare, hydrogel layer is and the direct contact layer of wound surface, can provide moisture for wound surface, keeps wound surface moistening, nonwoven layer can absorb wound exudate fast, in time with the sepage water conservancy diversion.
Description of drawings
Fig. 1 is this utility model structural representation;
Fig. 2 is this utility model top view;
In the accompanying drawing, the list of parts of each label representative is as follows: 1, release paper or mould release membrance, 2, hydrogel layer, 3, nonwoven layer, 4, the pre-gelatinized ventilative rete that blocks water, 5, support rete
The specific embodiment
Below in conjunction with accompanying drawing principle of the present utility model and feature are described, institute gives an actual example and only is used for explaining this utility model, is not be used to limiting scope of the present utility model.
As shown in Figure 1, profile is a kind of rectangular MULTILAYER COMPOSITE aerogel dressing, this utility model is five-layer structure, wherein, agent structure is hydrogel layer 2, hydrogel layer 2 is combined closely with nonwoven layer 3 by crosslinked, and on the pre-gelatinized medical adhesive belt 4 that one deck that nonwoven layer does not contact with hydrogel adheres to, structure 1 and 5 is release paper or mould release membrance.
During use, peel off release paper or mould release membrance 1, hydrogel layer 2 parts are aimed at wound surface, utilize size dimension than medical adhesive tape rete 4 partial fixings that hydrogel layer has more, aerogel dressing is fixed on the wound surface, tear and support rete 5.
The hydrogel of making in this way can absorb wound exudate fast, and air permeable waterproof, adhesion wound surface, comfortableness is strong and easy to use.
The above only is preferred embodiment of the present utility model, and is in order to limit this utility model, not all within spirit of the present utility model and principle, any modification of doing, is equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
