US Patent:

8467843, Jun 18, 2013
Filed:

Nov 4, 2009
Appl. No.:

12/612602
Inventors:

David R. Markle - Berwyn PA, US
Soya Gamsey - Huntington Beach CA, US
Thomas A. Peyser - Menlo Park CA, US
Assignee:

Glumetrics, Inc. - Irvine CA
International Classification:

A61B 5/00
US Classification:

600316, 600309, 600364, 600365, 600366
Abstract:

Embodiments of the invention are directed to an optical sensor for detecting blood glucose. The sensor comprises a chemical indicator system disposed within a gap between the distal end of an optical fiber and an atraumatic tip portion, wherein the optical fiber and atraumatic tip portion are coupled by a coupling member, such as a rod or hypotube or cage that traverses the gap. The sensor further comprises a means for generating and detecting an optical reference signal unrelated to the blood glucose, such that ratiometric correction of blood glucose measurements for artifacts in the optical system is enabled.

A61B 5/05
US Classification:

702 23, 702 19, 600345, 600347
Abstract:

Disclosed herein are methods of estimating an analyte concentration which include generating a signal indicative of the analyte concentration, generating a signal indicative of a temperature, generating a signal indicative of a pH, and transforming the signal indicative of the analyte concentration utilizing an equation of the form of a modified Michaelis-Menten equation depending on Michaelis-Menten parameters, wherein values of the Michaelis-Menten parameters are set based upon data which includes temperature and pH calibration parameters, the signal indicative of a temperature, and the signal indicative of a pH. Also disclosed herein are measurement devices which employ the aforementioned methods.

US Patent:

20110152658, Jun 23, 2011
Filed:

Dec 17, 2010
Appl. No.:

12/972385
Inventors:

Thomas A. Peyser - Menlo Park CA, US
Richard E. Purvis - Pasadena CA, US
David R. Markle - Berwyn PA, US
Soya Gamsey - Huntington Beach CA, US
Matthew A. Romey - Newport Beach CA, US
Assignee:

GLUMETRICS, INC. - Irvine CA
International Classification:

A61B 5/145
US Classification:

600365
Abstract:

Disclosed herein are methods and systems for generating an estimate of an in vivo analyte concentration and identifying whether the estimate is aberrant. In some embodiments, the system includes a sensor comprising an analyte sensor and a temperature sensing element, and a control unit programmed to identify changes in temperature that may indicate a non-physiologic condition (and result in an aberrant glucose measurement). In some embodiments, the methods include generating an estimate of analyte concentration at a particular time using the analyte sensor, and generating first and second signals indicative of temperature using the temperature sensing element. In some embodiments the methods include identifying the estimate of analyte concentration as aberrant if the magnitude of the difference between the first and second signals indicative of temperature exceeds a threshold value.
