Patent number: 7897109Abstract: Apparatus or systems which employ luminescence quenching to produce an oxygen concentration indicative signal. Components of such systems include: (1) an airway adapter, sampling cell, or the like having a sensor which is excited into luminescence with the luminescence decaying in a manner reflecting the concentration of oxygen in gases flowing through the airway adapter or other flow device; (2) a transducer which has a light source for exciting a luminescable composition in the sensor into luminescence and a light sensitive detector for converting energy emitted from the luminescing composition as that composition is quenched into an electrical-signal indicative of oxygen concentration in the gases being monitored; and (3) subsystems for maintaining the sensor temperature constant and for processing the signal generated by the light sensitive detector. Sensors for systems of the character just described, methods of fabricating those sensors, and methods for installing the sensors in the flow device.Type: GrantFiled: April 24, 2001Date of Patent: March 1, 2011Assignee: RIC Investments, LLCInventors: Lawrence L. Labuda, Perry R. Blazewicz, Leslie E. Mace, Jerry R. Apperson, Walter A. Cooke

Patent number: 7335164Abstract: An integrated airway adapter capable of monitoring any combination of respiratory flow, O2 concentration, and concentrations of one or more of CO2, N2O, and an anesthetic agent in real time, breath by breath. Respiratory flow may be monitored with differential pressure flow meters under diverse inlet conditions through improved sensor configurations which minimize phase lag and dead space within the airway. Molecular oxygen concentration may be monitored by way of luminescence quenching techniques. Infrared absorption techniques may be used to monitor one or more of CO2, N2O, and anesthetic agents.Type: GrantFiled: April 24, 2001Date of Patent: February 26, 2008Assignee: NTC Technology, Inc.Inventors: Leslie E. Mace, Lawrence L. Labuda, Perry R. Blazewicz, David R. Rich, Michael B. Jaffe, Joseph A. Orr, Scott A. Kofoed
