摘要

A device is provided for the protection of wounds comprising a shallow perforated bowl of substantially semicircular cross-section terminating at its edges in substantially flat rim portions and constructed of thermoplastic material selected from the group consisting of polyethylene, polypropylene and high pressure polypropylene or such stiffness that deflection thereof by a load of 1 kg applied from the convex side to the bowl throughout its bottom surface is less than the height of the bowl measured from its bottom surface to a plane defined by the rim portions, the shape of said bowl being in the form of an elongated depression having a length more than three times its width, said bowl being gridlike and formed with apertures separated by crossing bars, the dimensions of the cross-section of the bars taken in the direction of the surface of the bowl and at right angles to that direction being from about 1:1 to 1:1.5 to each other, and the area of the apertures exceeding the grid formed by the crossing bars.
