Fluoroelastomer Gasket For Blood Sensors

US Patent:
5700360, Dec 23, 1997
Filed:
Oct 31, 1995
Appl. No.:
8/550884
Inventors:
Andy D. C. Chan - Franklin MA
Mark W. Boden - Millbury MA
John S. Benco - Holliston MA
Robert A. Bergquist - Middleboro MA
Donna S. Orvedahl - Medfield MA
Assignee:
Chiron Diagnostics Corporation - E. Walpole MA
International Classification:
G01N 2726
US Classification:
204400
Abstract:
An elastomer, especially a fluoropolymeric elastomer, meets requirements necessary for use as a gasket in contact with primary membranes of electrochemical sensors of both blood gas and ionic species in blood. The elastomer can electrochemically seal an electrode of a diced chip (sensor) from a sample chamber, and can electrochemically seal electrodes of neighboring diced chips from each other. Significant simplicity in fabrication of multi-sensor analyzers and stopped-flow method using such analyzers is realized.
