  • Patent number: 4829993
    Abstract: A skin protective device to be positioned under a bandage to act as a barrier when the bandage is cut away in removal of it. The device is cut to a length somewhat longer than the bandage so that the opposite ends stick out. It is a flat thin bendable barrier strip of severable material having generally parallel side edges and a pair of main surfaces witih a first and a second end. The strip is encased in an envelope secured about the strip main surfaces. Marked along the length of the device on an outer main surface there may be indicia preferably in the form of a line extending longitudinally about midway between the edges so that one may be guided in cutting away a bandage and be certain in the knowledge that the barrier underlies it.
