The present invention is a flat dressing, comprising: a backing layer and a supporting layer, the supporting layer comprises a peripheral edge portion and an inner edge portion, wherein the edge of the peripheral edge portion and the edge of the backing layer are approximately fit, The inner edge portion is a hollow groove, and the area of the inner edge portion is smaller than the area of the backing material layer. When a surface of the support layer is connected with a surface of the backing material layer, an accommodation is formed space.

In a preferred embodiment of the present invention, the accommodating space completely penetrates the support layer.

In a preferred embodiment of the present invention, the support layer is a hydrophilic material, a silicone film, a collagen, a gauze, a non-woven fabric, a film dressing, a 3-D polymer foam, a water gel or any combination thereof.

In a preferred embodiment of the present invention, the flat dressing is in the shape of a square, a rectangle or a regular hexagon, so as to avoid material waste when the dressing is cut.

In a more preferred embodiment of the present invention, the inner edge portion of the support layer is in the shape of a circle, a rectangle, a square, or a regular hexagon.

In a better embodiment of the present invention, the flat dressing further comprises a plurality of flexible parts arranged around or at the apex of the flat dressing, so that the flat dressing can completely fit the affected parts at different angles and different parts. .

In a preferred embodiment of the present invention, the support layer further has an adhesive layer on the other side of the surface connected to the backing layer.

In a preferred embodiment of the present invention, it further comprises a release layer attached to the other side of the adhesive layer opposite to the support layer.

In a more preferred embodiment of the present invention, the release layer is a paper or a film layer.

In a more preferred embodiment of the present invention, it is a dressing suitable for chronic wound healing.

In a more preferred embodiment of the present invention, it is a dressing suitable for the recovery of pressure ulcers.

The preferred embodiments of the present invention will be described in detail as follows. The figures of the enumerated embodiments are the same as those shown in the figures. Please refer to the figures and detailed descriptions at the same time.

The following examples are not intended to limit the present invention, but are merely representative of several aspects and features of the present invention.

A flat dressing 1 of the present invention, as shown in FIG. 1a and FIG. 1b, includes: a backing layer 10 and a support layer 20, the support layer 20 includes a peripheral portion 201 and an inner peripheral portion 202, wherein the edge of the peripheral portion 201 is roughly in contact with the edge of the backing layer 10, the inner edge portion 202 is recessed inward toward the backing layer 10 or forms a hollow groove, and the inner The area of the edge portion 202 is smaller than the area of the backing layer 10 , and an accommodating space 30 is formed when a surface of the support layer 20 is connected with a surface of the backing layer 10 .

In order to make the flat dressing can effectively adapt to the skin, the support layer is composed of a hydrophilic material, a silicone film, a collagen, a gauze, a non-woven fabric, a film dressing, a 3-D polymer foam, a water Gel or any combination thereof, in embodiments of the present invention, the support layer is a hydrophilic material.

In order to avoid material waste during cutting during the manufacturing process of the flat dressing of the present invention, the flat dressing of the present invention can be square, rectangular or regular hexagon.

In the embodiment of the present invention, the best embodiment of the flat dressing is a regular hexagon, which saves material (second only to square or rectangle), and can provide better adhesion at joints or non-planar places .

Further, the shape of the inner edge portion is not necessarily the same as the shape of the flat dressing, and the shape of the inner edge portion may be a circle, a rectangle, a square or a regular hexagon.
