  • Fluid-retentive bandage
    Patent number: 5354261
    Abstract: A bandage which retains bodily fluids at least until such fluids reach the top of the dressing that may be placed in the bandage and which permits removal or replacement of the dressing without detaching the bandage from the patient. The bandage has a holder with a base portion which is adhesively attached to the skin of the patient and which contains an aperture to accommodate a wound. Connected to the base portion is at least one flap which folds over the dressing that may be inserted into the holder and which has a releasable fastener to close the holder, to maintain the dressing in a desired position, and to enable the bandage to be opened for inspection of the wound or replacement of the dressing. Fluid retention is accomplished by having the distal (with respect to the patient) edge of no flap closer to the patient's body than is the distal side of the dressing.
