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.

Claims

the clear plastic member having an upper surface and an opposite lower surface that is disposed contiguous to the site of the wound;

the clear plastic member further including an aperture centrally located thereon;

a plurality of wound measurement circles formed on the upper surface and concentrically arranged about the aperture and substantially covering the upper surface of the clear plastic member;

the concentric circles being radially spaced from each other in predetermined increments for allowing the length and width measurements of the wound;

an elongated depth gauge for insertion into and through the centrally located aperture so that the depth gauge is disposed at an orientation perpendicular to the clear plastic member;

the depth gauge further including a plurality of axially adjoined beads with each bead capable of incrementally and sequentially moving through the aperture during the advancement or retraction of the depth gauge for determining a base of the wound and for frictionally engaging the aperture when the base of the wound is found so that the depth gauge can be retained in that respective position relative to the clear plastic member; and

,

whereupon placement of the clear plastic member upon the wound and the incremental and sequential movement of each bead through the aperture until the base of the wound is found allows for the simultaneous measurement of the length, width and depth of the wound so that the clear plastic member can be lifted from the wound with the depth gauge being self-retained in position by the frictional engagement of one of the plurality of beads with the centrally located aperture so that wound assessment and recordation can be undertaken to be followed by the disposal of the clear plastic member and the depth gauge.

2. The disposable wound measuring device of claim 1 wherein the concentric measurement circles that are radially arranged about the centrally located aperture specifically measure the length and width of the wound.

3. The disposable wound measuring device of claim 2 further comprising a plurality of numerical indicators with each numerical indicator associated with one concentric measurement circle.

4. The disposable wound measuring device of claim 3 wherein each bead is spaced from the adjoining beads by a distance of ½

millimeter as measured from the centerline of each bead to the centerline of the adjoining beads.

5. The disposable wound measuring device of claim 4 wherein the advancement or retraction of the depth gauge through the centrally located aperture is by a positive incremental movement of ½

of a millimeter.

6. The disposable wound measuring device of claim 5 wherein the depth gauge includes a plurality of rigidity enhancing supports for supporting the beads in their axial attachment to each other.

7. The disposable wound measuring device of claim 6 wherein at least some of the beads of the depth gauge can be shaded or colored thereby creating an alternating pattern of colored and non-colored beads to facilitate the measurement of the depth of the wound.

8. A disposable wound measuring device for the simultaneous three-dimensional measurement and assessment of the length, width and depth of a wound, comprising:

a flexible clear plastic card for placement upon the site of the wound;

the flexible clear plastic card having an upper surface and an opposite lower surface that contacts the site of the wound and covers the wound;

the flexible clear plastic card further including an aperture centrally located thereon;

a plurality of wound measurement circles formed on the upper surface that are concentric to the aperture and radially extending outwardly from the aperture;

the concentric circles being radially spaced from each other in predetermined metrical increments thereby facilitating the measurements of the length and width of the wound;

an elongated depth gauge for insertion through the centrally located aperture so that the depth gauge is disposed at an orientation that is perpendicular to the flexible clear plastic card;

the depth gauge further including a plurality of beads adjoined in axial alignment with each other and capable of incremental and sequential passage through the aperture for advancing and retracting the depth gauge so that a deepest point of the wound can be determined; and

,

whereupon placement of the flexible plastic card upon the site of the wound and over the wound aligns the depth gauge with the wound so that the incremental and sequential movement of the beads through the aperture can be undertaken for finding the deepest point of the wound simultaneous with the wound measurement circles providing for the measurement of the length and width of the wound whereby the flexible plastic card can then be lifted off the wound with the depth gauge being self-retained in position to the flexible plastic card by the frictional engagement of one of the plurality of beads with the aperture for wound assessment followed by the disposal of the flexible plastic card and the depth gauge.

9. The disposable wound measuring device of claim 8 wherein the wound measurement circles formed on the upper surface of the flexible plastic card overlay the site of the wound for specifically measuring the length and width of the wound.

10. The disposable wound measuring device of claim 9 further comprising a plurality of numerical indicators formed on the upper surface of the flexible plastic card and with each numerical indicator associated with one wound measurement circle to facilitate length and width measurements of the wound.

11. The disposable wound measuring device of claim 10 wherein each bead is spaced from the adjoining beads by a distance of at least ½

millimeter as measured from the centerline of each bead to the centerline of the adjoining beads.

12. The disposable wound measuring device of claim 11 wherein the movement of the depth gauge through the aperture of the flexible plastic card is in sequential positive increments of at least ½

of a millimeter.

13. The disposable wound measuring device of claim 12 wherein the depth gauge includes a plurality of rigidity enhancing supports for supporting the beads in their axial attachment to each other.

14. The disposable wound measuring device of claim 13 wherein at least some of the beads of the depth gauge can be colored for creating an alternating pattern of colored and non-colored beads to thereby visually distinguish the beads from each other and facilitate the measurement of the depth of the wound.

15. A disposable wound measuring device for the simultaneous three-dimensional measurement of the length, width and depth of a wound, comprising:

a flexible clear plastic member having an upper surface, an opposite lower surface for placement on the wound, an aperture centrally located thereon, and a plurality of wound measurement circles formed on the upper surface that are concentric to the aperture and radially extend from the aperture;
