Publication number: 20120136336Abstract: A closed loop/semi-closed loop infusion system provides therapy modification and safeguards against the over-delivery or under-delivery of insulin. A glucose sensor system is configured to obtain a measured blood glucose value. A controller is operationally connected with the glucose sensor system and configured to trigger an alarm based on a measured blood glucose value or amount of insulin delivered, selectively perform calibration of the glucose sensor system when the alarm is triggered, and adjust a therapy delivery parameter when the alarm is triggered, wherein the adjusted therapy delivery parameter is limited to be within a boundary. Thereafter, a delivery system delivers therapy at the adjusted therapy delivery parameter.Type: ApplicationFiled: February 6, 2012Publication date: May 31, 2012Applicant: MEDTRONIC MINIMED, INC.Inventors: John J.

Publication number: 20120059673Abstract: A diabetes data management system selects variable threshold parameters that are utilized in a report. A first low threshold glucose reading and a first high threshold glucose reading for a before meal event timeframe are selected. A second low threshold glucose reading and a second high threshold glucose reading are selected for an after meal event timeframe. The threshold readings are stored in a database. The diabetes data management system analyzes glucose behavior around meal events. The system receives a plurality of glucose readings for a time period, receives a first time range as a pre-meal analysis period for the first meal event and receives a second time range as a post-meal analysis period for the first meal event. The system creates a graph which highlights the pre-meal analysis period, the post-meal analysis period, and displays the plurality of glucose readings for the time period.Type: ApplicationFiled: November 10, 2011Publication date: March 8, 2012Applicant: MEDTRONIC MINIMED, INC.Inventors: Gary COHEN, John J. MASTROTOTARO, Keith DEBRUNNER, Steven B. HOBMANN

Publication number: 20110218489Abstract: A closed loop system or semi-closed loop system for infusing insulin using sensor values applies a redundant sensor system as a fail-safe method against sensor failure. The redundant glucose sensors are used corroborate each other and a failing sensor is detected if the sensors no longer corroborate each other. The use of redundant sensors has the additional benefit of producing better sensor signals compared to the use of a single sensor.Type: ApplicationFiled: April 13, 2011Publication date: September 8, 2011Applicant: MEDTRONIC MINIMED, INC.Inventors: John J.

Publication number: 20100268477Abstract: A method of calibrating glucose monitor data includes collecting the glucose monitor data over a period of time at predetermined intervals, obtaining reference glucose values from a reference source that temporally correspond with the glucose monitor data obtained at the predetermined intervals, calculating the calibration characteristics using the reference glucose values and corresponding glucose monitor data to regress the obtained glucose monitor data, and calibrating the obtained glucose monitor data using the calibration characteristics. In additional embodiments, calculation of the calibration characteristics includes linear regression and, in particular embodiments, least squares linear regression. Alternatively, calculation of the calibration characteristics includes non-linear regression. Data integrity may be verified and the data may be filtered.

Publication number: 20100010330Abstract: A monitor device for a fluid infusion system and its operating, display, and data processing characteristics are described herein. One embodiment of the monitor device is used in an insulin infusion system having an insulin infusion pump and a continuous glucose sensor transmitter. The monitor device is configured as a wireless bedside monitor that wirelessly receives status data from a device in the fluid infusion system, such as the infusion pump or the sensor transmitter. The monitor device supports a number of user interface features, alarm/alert features, and graphical display features, where such features enhance the overall operation and user-friendliness of the monitor device. For example, the monitor device can generate status icons that graphically indicate the time remaining for an exhaustible operating quantity of a device in the infusion system (e.g., a battery charge, a fluid reservoir volume, or a calibration or replacement period).Type: ApplicationFiled: September 22, 2009Publication date: January 14, 2010Applicant: MEDTRONIC MINIMED, INC.Inventors: Ulrich Rankers, Bradley J.

Publication number: 20090234213Abstract: An infusion system is for infusing a fluid into the body of a patient. The infusion system includes at least one sensor for monitoring blood glucose concentration of the patient and an infusion device for delivering fluid to the patient. The sensor produces at least one sensor signal input. The infusion device uses the at least one sensor signal input and a derivative predicted algorithm to determine future blood glucose levels. The infusion device delivers fluid to the patient when future blood glucose levels are in a patient's target range. The infusion device is capable of suspending and resuming fluid delivery based on future blood glucose levels and a patient's low shutoff threshold. The infusion device suspends fluid delivery when future blood glucose levels falls below the low shutoff threshold. The infusion device resumes fluid delivery when a future blood glucose level is above the low shutoff threshold.Type: ApplicationFiled: May 6, 2009Publication date: September 17, 2009Applicant: MEDTRONIC MINIMED, INC.Inventors: Andrew C.
