Optical Sensor For Fluid Parameters

US Patent:
5335305, Aug 2, 1994
Filed:
Oct 23, 1992
Appl. No.:
7/965232
Inventors:
Nadhir B. Kosa - The Woodlands TX
Gene J. Twiggs - Magnolia TX
James R. Salter - The Woodlands TX
Raghuvir Singh - The Woodlands TX
David J. Costello - Spring TX
Leslie A. Schlain - Woodlands TX
Assignee:
OPtex Biomedical, Inc. - The Woodlands TX
International Classification:
G02B 638
US Classification:
385147
Abstract:
Methods for making optical fiber sensor probes for measuring or monitoring parameters of fluids, including but not limited to measuring blood gas concentrations and pH either in a vessel in vitro or in a human artery. Such probes, in one aspect, have one or more optical fibers with one or more chambers with a chemical indicating materialtherein which changes in response to light transmitted therethrough. In one aspect such probes have a probe body including a plurality of fibers having a substantial portion of their surfaces covered with an opaque material to enhance light signal transmission therethrough. Such probes may also have a coating thereon of an anti-thrombogenic mnaterial.

Sensor Calibrator And Test Apparatus

US Patent:
5207087, May 4, 1993
Filed:
Apr 17, 1991
Appl. No.:
7/688463
Inventors:
David J. Costello - Spring TX
Assignee:
Optex Biomedical, Inc. - The Woodlands TX
International Classification:
G01D 1800
US Classification:
73 1G
Abstract:
Methods and apparatuses for testing chemical concentrations of fluids (liquids, gases) and for sensors used in such tests; methods and apparatuses for calibrating sensors and, in particular, for calibrating optical fiber sensors, the apparatus in one aspect including a body member with a cavity having gas inlet(s) and outlet(s) and a microporous tube therein for holding a fluid into which an optical probe sensor is insertable.

Method For Making Optical Probe

US Patent:
5397411, Mar 14, 1995
Filed:
Dec 19, 1991
Appl. No.:
7/810479
Inventors:
David J. Costello - Spring TX
James R. Salter - The Woodlands TX
Leslie A. Schlain - The Woodlands TX
Nadhir B. Kosa - The Woodlands TX
Raghuvir Singh - The Woodlands TX
Assignee:
Optex Biomedical, Inc. - The Woodlands TX
International Classification:
B29C 3508, B29C 5336, B29C 6514
US Classification:
156154
Abstract:
A method for making an optical fiber bundle which, in one aspect, includes bending each of a plurality of optical fibers to form a bend therein and then suspending the fibers over a suspension member; holding the fibers taut under tension; applying potting material to the fiber bends and curing it; and removing the fibers from the suspension member.
