Patent number: 8591416Abstract: A sensor system includes a sensor and a sensor electronics device. The sensor includes a plurality of electrodes. The sensor electronics device includes a connection detection device, a power source, and a delay circuit. The connection detection device determines if the sensor electronics device is connected to the sensor and transmits a connection signal. The delay circuit receives the connection signal, waits a preset hydration time, and couples the regulated voltage from the power source to an electrode in the sensor after the preset hydration time has elapsed. Alternatively, the sensor electronics device may include an electrical detection circuit and a microcontroller. The electrical detection circuit determines if the plurality of electrodes are hydrated and generates an interrupt if the electrodes are hydrated. A microcontroller receives the interrupt and transmits a signal representative of a voltage to an electrode of the plurality of electrodes.Type: GrantFiled: September 21, 2010Date of Patent: November 26, 2013Assignee: Medtronic Minimed, Inc.Inventors: Rajiv Shah, Wayne A. Morgan, David Y. Choy, James L. Henke, Bahar Reghabi, Gopikrishnan Soundararajan, Peter Schultz, Udo Hoss

Publication number: 20110130988Abstract: A blood glucose sensing system includes a sensor and a sensor electronics device. The sensor includes a plurality of electrodes. The sensor electronics device includes stabilization circuitry. The stabilization circuitry causes a first voltage to be applied to one of the electrodes for a first timeframe and causes a second voltage to be applied to one of the electrodes for a second timeframe. The stabilization circuitry repeats the application of the first voltage and the second voltage to continue the anodic-cathodic cycle. The sensor electronics device may include a power supply, a regulator, and a voltage application device, where the voltage application device receives a regulated voltage from the regulator, applies a first voltage to an electrode for the first timeframe, and applies a second voltage to an electrode for the second timeframe.Type: ApplicationFiled: January 11, 2011Publication date: June 2, 2011Applicant: MEDTRONIC MINIMED, INC.Inventors: RAJIV SHAH, Bahar Reghabi, James L.

Patent number: 5064412Abstract: An ultrasonic air-in-line detection system for use in detecting air bubbles in the fluid line of a disposable cassette mounted on a main pump unit is disclosed which can accurately detect air bubbles in any type of fluid, whether clear or opaque. The system uses a windowing technique to determine when a threshold amount of air bubbles in a predetermined volume of material pumped occurs, with the alarm being sounded only when this threshold amount of air bubbles is present in the window volume. The system of the present invention thus avoids so-called nuisance alarms due to the presence of small isolated air bubbles in the fluid due to the fluid pumped not having been degassed.Type: GrantFiled: September 5, 1989Date of Patent: November 12, 1991Assignee: Pacesetter Infusion, Ltd.Inventors: James L. Henke, Paul A. Koenig
