  • Patent number: 4526166
    Abstract: A bandage includes first and second carrier strips, the first strip carrying a liquid absorbent, soft, pad of material which is to be placed over a wound. The second strip carries an adhesive to be placed onto the patient's skin at a location spaced from the wound. The two strips have ends which are connected by a releasable attachment forming a third element such as a tear string which is easily manipulable to free the strips from one another. This enables lifting of the pad and first strip independently of the second strip, so that force applied to the second strip to free it from the skin is not transferable to the first strip and wound.
