Abstract

Abstract A biological fiber optic probe chemical indicator device is disclosed. Structurally, the probe comprises at least one strand of optical fiber terminating in a coupling arrangement with a disposable sleeve assembly including a chemical indicator system for physiological substances. The disposable sleeve sensor element comprises a tubular housing with annular wall portions defining a female coupling channel means and a casing for a chemical reagent indicator.
