Abstract
Abstract An antimicrobial orthopedic pin percutaneous protection kit is provided comprising a shield and a pad and patch combination. The shield comprises a central elastomeric collar having a longitudinal orifice and having one end of the collar substantially orthogonally disposed to an elastomeric peripheral flange, the flange extending around the end of the collar, with a radial slit extending through the collar and flange from the longitudinal orifice of the collar to the outer edge of the flange. The shield is adapted with a means for securing the collar around an orthopedic pin to prevent longitudinal motion of the pin. The patch contains an antimicrobial agent and is centrally attached to a porous pad. The pad and patch have a pressure-sensitive adhesive coating on the exposed surfaces.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
213 words
An antimicrobial orthopedic pin percutaneous protection kit comprising a shield comprising a central elastomeric collar having a longitudinal orifice and having one end of said collar orthogonally disposed to an elastomeric, porous, peripheral flange, said flange extending around said end of said collar; and an absorbent patch containing an antimicrobial agent wherein said patch is centrally attached to a porous pad, said pad having a pressure-sensitive adhesive coating on the exposed surface thereof; the maximum dimensions of said pad being such that when said pad is placed upon the skin of a patient the superimposition of said shield upon said pad prevents contact of said flange upon the skin of said patient; wherein a first radial slit extends through said collar and flange from said longitudinal orifice of said collar to the circumferential edge of said flange to provide a lateral insertion route of an orthopedic pin into said collar; and a second radial slit extends from a central point of said pad and patch to the respective circumferential edges of said pad and said patch to provide a lateral insertion route of said orthopedic pin into said central point; said shield adapted with means for securing said collar around said orthopedic pin to prevent longitudinal motion of said pin through said collar.
