Publication number: 20060106345Abstract: Disclosed is an interface between a drug delivery cassette and a medical effector system. The cassette may be mounted to the medical effector system in such a way that a fluid tube located on the cassette is positioned adjacent to a pump located on the medical effector system. The medical effector system may purge the fluid line of air by activating the pump and forcing fluid through the fluid line until a sensor positioned to monitor the fluid line indicates that fluid and not air is present in the tube. To prevent air purging of the fluid tube when connected to the patient, the medical effector system prohibits air purging unless the drug delivery end portion of the fluid tube is in a designated storage site located on the cassette. This is accomplished with a position sensor at the storage site that monitors the position of the fluid tube.Type: ApplicationFiled: June 21, 2005Publication date: May 18, 2006Inventors: Richard Flaker, Mark Burdorff, Gregory Bishop, DeWayne Davis, William Donofrio, Curt Eyster, Hal Katz, David Keilholz, Ross Krogh, Michael Miller, Anil Nalagatla, Paul Niklewski, Jeffery Wuennemann, Jason Derouen

Publication number: 20060042635Abstract: Disclosed is a capnometry apparatus for receiving respiratory gas from a respiratory cannula positioned on a patient. An integrated host controller alerts a user if the capnometry apparatus is connected or not connected to the respiratory cannula based in part on a signal output from a capnometer located in the capnometry apparatus. The host controller also includes the functionality to shut off the capnometer pump with or without a time delay when the capnometer signal output indicates the capnometer pump is not connected to the cannula. An ambient-air pressure sensor located in the capnometry apparatus alerts the host controller if the capnometry apparatus has been moved to a new location with a substantially different altitude than the first location, in which case the host controller will issue an alert to a user prompting a calibration of the capnometry apparatus.Type: ApplicationFiled: June 21, 2005Publication date: March 2, 2006Inventors: Paul Niklewski, Mark Burdorff, William Donofrio, Curt Eyster, James Martin, Anil Nalagatla, William Adair, Nicholas Cobb
