Abstract
A disposable wound measuring device for making simultaneous three-dimensional (length, width and depth) measurements of a wound or ulcer to facilitate wound care assessment and healing that includes a flexible, clear plastic planar card or member superposed on the wound and having a centrally located aperture and concentric circles radially arranged about the aperture, and an elongated depth gauge insertable through the aperture and incrementally adjustable either vertically or obliquely through the aperture and relative to the wound surface and the plastic member for making a wound depth measurement with the depth gauge being retained in position by a plurality of beads equidistantly spaced along the gauge and slightly larger in diameter than the aperture thereby self-retaining the depth gauge in a particular position for making the wound depth measurement.
