Fixation pin entry site dressing and method
First Claim
1. An external fixation pin site dressing comprising an elongate body of soft, compressible, resilient and highly-absorbent material having a longitudinal primary slit extending inwardly from one side of said body;
- and a plurality of pairs of transverse slits extending inwardly from opposite sides of said body and partially dividing said body into a multiplicity of segments;
said transverse slits of each pair being coplanar and having inner edges spaced apart to define a narrow connecting septum between adjacent segments;
each septum providing a tearable connection between adjacent segments permitting separation of a single segment, or a selected number of joined segments, from the remainder of said body so that said separated segment or segments may be longitudinally compressed and fitted onto a portion of a fixation pin extending between a patient'"'"'s skin and a fixation pin bracket with such pin portion being fully received in said longitudinal primary slit.

Abstract
An external fixation pin entry site dressing, and the method of its application, in which an elongate body of soft, tearable, and compressible absorbent material has a longitudinal primary slit extending inwardly from one side of the body to about the longitudinal midline thereof and a plurality of pairs of transverse slits extending inwardly from opposite sides of the body and partially dividing the body into a multiplicity of separable segments. A user compares the length of a portion of a fixation pin, exposed between a mounting bracket and the skin at the entry point for the pin, with the thickness of one or more of the segments while the dressing is in an uncompressed condition, tears the dressing apart along one of the central septa connecting adjacent segments to separate from the block one or more segments having a total thickness in an uncompressed state greater than the exposed length of fixation pin, and then compresses the separated segment(s) and fits such separated segment(s) onto the fixation pin with the portion of the pin between the bracket and the skin being received in the primary slit.

11. A method of dressing the entry site for a fixation pin extending from a mounting bracket through the surface of a patient'"'"'s skin and into a bone therebeneath, comprising the steps of providing a block of soft, compressible, resilient and highly-absorbent material having a longitudinal primary slit extending along the block'"'"'s longitudinal midline and a plurality of pairs of transverse slits extending inwardly from opposite sides of said block and partially dividing said block into a multiplicity of segments connected in series by narrow integral septa;
- comparing the distance between said mounting bracket and a patient'"'"'s skin with a thickness of one or more of said uncompressed segments;
tearing a septum to separate from said block one or more segments having a total thickness in an uncompressed state greater than said distance;
then longitudinally compressing said one or more separated segments to a thickness less than said distance;
fitting said one or more separated segments, while compressed, onto said fixation pin with the portion of said pin between said bracket and said skin being received in said primary slit; and
relieving the compressive force to allow said one or more segments to expand longitudinally into contact with said bracket and said skin. - View Dependent Claims (12, 13)
- comparing the distance between said mounting bracket and a patient'"'"'s skin with a thickness of one or more of said uncompressed segments;
