AI Technical Summary
Technical Problem
Existing catheters often experience fluid infiltration into surrounding tissues due to poor placement or dislodgement, leading to leaks and requiring immediate detection and corrective action.
Method used
A sensor assembly comprising two elongate sensor members with distinct markings and adhesive components, allowing translation relative to each other to visually or electronically indicate fluid infiltration at the catheter site.
Benefits of technology
Enables rapid identification of fluid infiltration, facilitating timely intervention to prevent further leakage and reduce swelling or discomfort.

Abstract
A sensor for detecting infiltration at a catheter infusion site may include a first elongate sensor member couplable to a first location proximate the catheter infusion site, and a second elongate sensor member couplable to a second location proximate the catheter infusion site. The first elongate sensor member may include a first marking and the second elongate sensor member may include a second marking. The first elongate sensor member may slidably couple with and translate relative to the second elongate sensor. The first and second markings may indicate a range of relative positions between the first and second elongate sensor members as the first and second elongate sensor members translate relative to each other. At least one relative position within a range of relative positions between the first and second elongate sensor members may be indicative of infiltration at the catheter infusion site.
