Patent number: 9091676Abstract: Systems and methods for analyzing multiple components of a fluid sample are provided. In certain embodiments, a system can include an analyte detection system configured to measure first analyte data in a first component of a fluid sample received from a patient and measure second analyte data in a second component of a fluid sample. In some embodiments, one or more portions of an optical system is movable with respect to other portions of the system in order to optically and/or electrochemically analyze multiple components of a fluid sample. In other embodiments, optical and/or electrochemical analysis can be performed simultaneously on multiple components of a fluid sample. In some embodiments, a first analyte can be measured in a sample (e.g., whole blood) before the sample is separated into its components (e.g., plasma, red blood cells, etc.), and a second analyte can be measured in a component of the sample after separation.Type: GrantFiled: June 8, 2011Date of Patent: July 28, 2015Assignee: OptiScan Biomedical Corp.Inventors: Peter Rule, James R. Braig, Richard Keenan, II, David Callicoat

Patent number: 8731639Abstract: Methods and systems for determining the concentration of one or more analytes from a sample such as blood or plasma are described. The systems described herein can be configured to withdraw a sample from a source of fluid, direct a first portion of the withdrawn sample to an analyte monitoring system and return a second portion of the sample. The analyte monitoring system can be connected to the fluid source via a connector that is configured to improve fluid flow and reduce blood clotting risk. These goals can be accomplished, for example, by employing coatings in or on a connector, positioning a resilient substance at or near the junction, by reducing dead space volume, by using resiliency to improve fit, by extending a portion of one connector to better mate with a portion of another connector, etc.Type: GrantFiled: May 3, 2011Date of Patent: May 20, 2014Assignee: OptiScan Biomedical CorporationInventors: David Callicoat, Monnett Soldo, Craig Johnson, Salvador Zamora, Michael Butler, Eugene Lim

Publication number: 20080072663Abstract: A method of extracting and analyzing bodily fluids from a patient at the point of care for the patient is provided. The method comprises establishing fluid communication between an analyte detection system and a bodily fluid in the patient. A portion of the bodily fluid is drawn from the patient. A first component of the bodily fluid is separated from the drawn portion, while the analyte detection system remains in fluid communication with the patient. The analyte detection system analyzes the first component to measure a concentration of an analyte in an accurate and timely manner.Type: ApplicationFiled: August 15, 2007Publication date: March 27, 2008Applicant: OptiScan Biomedical CorporationInventors: Richard Keenan, Jeffrey Chiou, Roger Tong, Michael Recknor, Ken Li, James Braig, David Callicoat, Jennifer Gable

Publication number: 20070103678Abstract: An apparatus for analyzing the composition of bodily fluid. The apparatus comprises a fluid handling network including a patient end configured to maintain fluid communication with a bodily fluid in a patient. The apparatus further comprises a pump unit in operative engagement with the fluid handling network. The pump unit has an infusion mode in which the pump unit is operable to deliver infusion fluid to the patient through the patient end, and a sample draw mode in which the pump unit is operable to draw a sample of the bodily fluid from the patient through the patient end. The apparatus further comprises a spectroscopic analyzer configured to obtain spectra from at least a portion of the sample, and a processor in communication with or incorporated into the spectroscopic analyzer.Type: ApplicationFiled: December 21, 2005Publication date: May 10, 2007Inventors: Bernhard Sterling, W. Hall, David Callicoat, Jennifer Gable, James Braig, Kenneth Witte, Mark Wechsler, Richard Keenan, Richard King

Publication number: 20070060872Abstract: An apparatus is provided for monitoring a predetermined parameter of a patient's body fluid while infusing an infusion fluid into the patient. The apparatus comprises an infusion line and a catheter configured for insertion into a blood vessel of the patient, and a reversible infusion pump connected between a source of an infusion fluid and the infusion line and catheter. The apparatus further comprises a body fluid sensor assembly mounted in fluid communication with the infusion line and which includes a first sensor and a sample cell. The first sensor provides a signal indicative of a predetermined parameter of any fluid present in the infusion line. The sample cell is substantially transmissive to light comprising a wavelength ?. The apparatus further comprises a controller that is configured to operate the infusion pump in a forward direction so as to pump the infusion fluid through the infusion line and catheter for infusion into the patient.Type: ApplicationFiled: February 13, 2006Publication date: March 15, 2007Inventors: W. Hall, David Callicoat, Jennifer Gable, James Braig, Kenneth Witte, Mark Wechsler, Peter Rule, Richard Keenan

Publication number: 20060217636Abstract: In some arrangements, a dermal lance apparatus is adapted to pierce a person's skin to obtain bodily fluids for medical testing. The lance can stimulate nerves in the person's skin to reduce or eliminate pain during the lancing procedure. After the nerves are stimulated, the lance can form the opening at a lance point. The lance can use mechanical motion to stimulate the person's skin. Alternatively, the lance can affect the temperature of the person's skin for effective stimulation.Type: ApplicationFiled: March 28, 2005Publication date: September 28, 2006Inventors: James Braig, David Callicoat
