Abstract: A wound dressing device for dispensing individual wound dressings on demand from a roll of a multitude of identical wound dressings is described. Each individual wound dressing has a coarse open weave pad of gauze or other material containing a therapeutic agent provided with adhesive wings on the outer sides of the pad arranged in spaced end to end relationship with adjacent wound dressings sandwiched between a continuous backing strip located on one side and a continuous protective strip located on the other side. The roll of wound dressings is contained within a replaceable cassette that can be clipped onto a housing fixed to a wall of a room. The housing is provided with an operating subassembly having an operating lever. The subassembly interacts with the cassette to advance the wound dressings one at a time through the dispenser when the lever is moved to operate the subassembly.
