Publication number: 20210186417Abstract: Disclosed are methods and apparatus for determining analyte concentration in a sample such as bodily fluid. Systems and methods disclosed herein can also include a treatment dosing system to infuse or inject a treatment drug (e.g., insulin or glucose) and provide glycemic control. The dose of the treatment drug may be based on the concentration of th4e analyte or the average value for the concentration of the analyte and/or the rate of change of the value of the concentration of the analyte.Type: ApplicationFiled: October 28, 2020Publication date: June 24, 2021Inventors: James R. Braig, Richard Keenan, Peter Rule, Gil Rivas, Mahesh Seetharaman

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
