In order to achieve the above purpose, the medical dressing of the utility model adopts the following technical scheme:
The utility model provides a medical dressing, including the non-woven fabrics base layer, the notch has been seted up at non-woven fabrics base layer up end middle part, be provided with the antibacterial layer in the notch, antibacterial layer up end is parallel and level mutually with non-woven fabrics basic unit up end, the second notch has been seted up at antibacterial layer up end middle part, be provided with the adsorbed layer in the second notch, adsorbed layer up end is parallel and level mutually with non-woven fabrics basic unit up end, the third notch has been seted up at adsorbed layer up end middle part, be provided with the hemostatic layer in the third notch, hemostatic layer up end protrusion is in non-woven fabrics basic unit up end, hemostatic layer upside still is provided with from the type ply, from the type ply still covers non-woven fabrics basic unit up end.
The medical dressing is further improved in that the outer edge of the upper end face of the non-woven fabric base layer is provided with an adhesive layer.
The medical dressing is further improved in that the lower end surface of the non-woven fabric base layer is also provided with a waterproof breathable layer.
The medical dressing is further improved in that a tough belt is embedded in the middle of the outer peripheral side of the non-woven fabric base cloth layer.
The medical dressing is further improved in that two groups of non-woven fabric base cloth layers, antibacterial layers, adsorption layers and hemostatic layers are arranged and are symmetrically distributed up and down, and the release paper layers are shared.
Compared with the prior art, the utility model has the beneficial effects that:
The hemostatic layer, the adsorption layer, the antibacterial layer and the non-woven fabric base layer are all arranged from top to bottom and from inside to outside, so that the hemostatic and antibacterial effects of the front dressing at the wound surface are ensured, and the suction permeation antibacterial effects at the peripheral side of the wound surface are also ensured. On the other hand, the release paper layer is arranged to effectively protect the functional surface layer, so that the service life of the dressing is guaranteed, and meanwhile, the release paper layer is used in the positive and negative directions, so that resources are saved.
Drawings
FIG. 1 is a schematic diagram of the structure of the present utility model;
In the figure: 1a non-woven fabric base cloth layer, 2 a bacteriostatic layer, 3 an adsorption layer, 4a hemostatic layer, 5 a release paper layer and 6 a ductile tape.
Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
As shown in fig. 1, a medical dressing comprises a non-woven fabric base layer 1, wherein a notch is formed in the middle of the upper end surface of the non-woven fabric base layer, a bacteriostatic layer 2 is arranged in the notch, the upper end surface of the bacteriostatic layer is flush with the upper end surface of the non-woven fabric base layer, a second notch is formed in the middle of the upper end surface of the bacteriostatic layer, an adsorption layer 3 is arranged in the second notch, the upper end surface of the adsorption layer is flush with the upper end surface of the non-woven fabric base layer, a third notch is formed in the middle of the upper end surface of the adsorption layer, a hemostatic layer 4 is arranged in the third notch, the upper end surface of the hemostatic layer protrudes out of the upper end surface of the non-woven fabric base layer, a release paper layer 5 is further arranged on the upper side of the hemostatic layer, and the release paper layer further covers the upper end surface of the non-woven fabric base layer.
