Claims16
A wound debridement device comprising:
- a first foam layer coupled to a second foam layer that is different from the first foam layer;
- wherein the first foam layer has a thickness measured from a first surface that is exposed to a second surface that is coupled to the second foam layer;
- wherein the first surface includes a central portion and an edge portion surrounding an entirety of the central portion, where the central portion is provided with a plurality of grooves formed in the first surface, where each groove of the plurality of grooves extends into the first surface a groove distance that is less than the thickness of the first layer;
- wherein the wound debridement device is adapted to clean a wound by capturing and retaining wound debris in the plurality of grooves by configuring:
- the first foam layer to comprise pores in a range from 70-90 pores per inch with a Compression Load Deflection measured at 25% in a range between 0.30 to 0.40 psi, and
- the second foam layer to comprise pores in a range from 40-50 pores per inch and a Compression Load Deflection measured at 25% in a range between 0.40 to 0.50 psi.
