Publication number: 20200383620Abstract: Systems and method are disclosed for determining a concentration of an analyte in a fluid (e.g., blood). The system can draw blood from a patient and deliver the blood to a sample cell. A particular component of the fluid (e.g., plasma) may be separated and/or positioned such that the concentration of the analyte is measured in the particular component of the fluid (e.g., plasma). The sample cell can include a sample container that has two window pieces. The system can have a fluid passage having a tip configured to mate with a multi-lumen catheter without leaking. The multi-lumen catheter can have proximal and distal ports. A fluid pressure system can be configured to periodically draw fluid from vasculature through a proximal intravascular opening and the proximal port while maintaining a low pressure and/or flow rate to thereby reduce risk of reversing the fluid flow in a vessel and drawing infusates upstream into another intravascular opening.Type: ApplicationFiled: May 19, 2020Publication date: December 10, 2020Inventors: Eugene Lim, Roger Tong, Peter Rule, James R. Braig, Richard Keenan, David N. Callicoat, Michael Butler, Craig A. Johnson

Publication number: 20200345285Abstract: 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can be configured to withdraw a certain volume of sample from a source of bodily fluid, direct a first portion of the withdrawn sample to an analyte monitoring system and return a second portion of the sample to the patient. The analyte monitoring system can be connected to the source of bodily fluid via a connector that is configured to maintain uniform velocity across the connector and reduce the dead space volume.Type: ApplicationFiled: July 15, 2020Publication date: November 5, 2020Inventors: Michael Butler, Eugene Lim, Craig Johnson

Patent number: 10677688Abstract: Various medical systems and methods are described, including a medical monitoring system. The medical monitoring system can have a fluid system configured to receive bodily fluid and optically analyze said fluid to determine analyte concentration. The fluid system can have a removable portion. The removable portion can have an opening with a port. The system can also have a container configured to contain anticoagulant. The container can have a portion configured to mate with the port of the removable portion. The container can be further configured to not fit into a conventional luer fitting. An anti-coagulant insertion apparatus is also described. The apparatus can have a syringe, a dock with a port, and an adapter configured to connect the syringe to the port. The dock can also have a tab configured to move with the port.Type: GrantFiled: April 18, 2017Date of Patent: June 9, 2020Assignee: OptiScan Biomedical CorporationInventors: Gil Rivas, Michael Butler, Jeffrey T.

Patent number: 10307760Abstract: One example of systems and methods for inertio-elastic focusing of particles in microchannels includes a substrate including a channel having an inlet and an outlet. A viscoelastic fluid, i.e., a fluid having a dynamic viscosity that varies with shear rate, and that carries suspended particles is driven through the channel. The volumetric flow rate at which the fluid is driven results in the formation of a localized pathline in the fluid at or near a center of the channel. The localized pathline defines a width that is equal to or slightly greater than a hydraulic diameter of the particle. The particles in the fluid are focused into the localized pathline.Type: GrantFiled: January 30, 2015Date of Patent: June 4, 2019Assignees: The General Hospital Corporation, Massachusetts Institute of TechnologyInventors: Mehmet Toner, Gareth McKinley, Eugene Lim, Thomas Ober

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: ApplicationFiled: July 23, 2018Publication date: December 6, 2018Inventors: Michael Butler, Eugene Lim, Craig Johnson
