Classification: CPC A | IPC A

Claim 7:
8. A sensor for detecting infiltration at catheter infusion site comprising:
a first elongate sensor member configured to couple to a patient at a first location proximate a catheter infusion site;
a second elongate sensor member configured to couple to the patient at a second location proximate the catheter infusion site;
at least one first marking coupled to the first elongate sensor member; and
at least one second marking coupled to the second elongate sensor member;
wherein:
the first elongate sensor member is slidably coupled to the second elongate sensor member such that the first and second elongate sensor members are translatable relative to each other, wherein the first elongate sensor member is configured to translate with respect to the second elongate sensor member in response to infiltration at the catheter infusion site;
the at least one first and second markings are configured to 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; and
at least one relative position within a range of relative positions between the first and second elongate sensor members is indicative of infiltration at the catheter infusion site.
