  • Publication number: 20140344280
    Abstract: Continuous glucose monitoring (CGM) data and insulin delivery data are used to generate more reliable projected alarms related to a projected glucose levels. A memory stores endogenous data related to measurements of glucose level in a patient, and also stores exogenous data, such as insulin on board, both of which are used by a processor to create projected alarms. Profiles of CGM data are created for use in tuning patient-specific insulin data, such at basal rate, carb ratio, and insulin sensitivity. A processor searches for patterns in the data profiles and if found, recommended changes to patient-specific insulin data are provided to permit more accurate control over a patient's glucose levels.

  • Publication number: 20140180203
    Abstract: Safety features are applied to an integrated insulin delivery system to enhance safety by controlling medication delivery including the automatic resumption of basal rate after a particular event, such as termination of a bolus, expiration of a time period, delayed resumption after the bolus has terminated, IOB comparison, and others. Other safety features include overriding a delivery control that may result in hypoglycemia, and terminating an extended bolus or temporary basal rate in view of a glucose signal indicating imminent carbohydrate deficiency. In another feature, an automatic resumption of a basal delivery rate is programmed into the delivery device to avoid the possibility of complete loss of delivery of insulin in the event that communication with the delivery device is disrupted.

  • Patent number: 8579854
    Abstract: An integrated insulin delivery system having safety features for controlling medication delivery includes automatic resumption of basal rate after a particular event, such as termination of a bolus, expiration of a time period, delayed resumption after the bolus has terminated, IOB comparison, and others. Other safety features include overriding a delivery control that may result in hypoglycemia, terminating an extended bolus or temporary basal rate in view of a glucose signal indicating imminent carbohydrate deficiency, and controlling the delivery rate to take an asymmetrical bias range of a glucose sensor into account to avoid hypoglycemia.

  • Patent number: 8257300
    Abstract: Safety features are applied to an integrated insulin delivery system to enhance safety while accounting for glucose sensor bias and calibration errors. One safety feature includes comparisons of calibrations of the sensor to nominal sensitivity and taking action, such as limiting insulin delivery or taking a further calibration of the sensor. In another feature, an automatic resumption of a basal delivery rate is programmed into the delivery device to avoid the possibility of complete loss of delivery of insulin in the event that communication with the delivery device is disrupted. Other features include steps taken to avoid hypoglycemia in the event that the sensor is negatively biased.

  • Publication number: 20110166875
    Abstract: System and method receive medical data of a patient having a disease afflicted health condition for processing and analysis of that data. Software installed on a health care provider's computer for processing the medical data includes a GUI reimbursement window that informs the HCP of reimbursement possibilities for analysis of the data and counseling of the patient. The reimbursement window also includes hyperlinks and may also include codes for insurance claims. Lists of reimbursement entities, pre-authorization instructions, coding instructions, and contacts may all be included and may be personalized for a particular patient. In one case, a complete bill is created and submitted to an insurance entity. In another, a patient data base is created so that the reimbursement window can inform the HCP of patient analysis frequency, which may affect reimbursement.

  • Publication number: 20100305965
    Abstract: A system for generating a report having varying integrated levels of medical information related to a health condition is provided. The system comprises a host server having a host database and a client component that connects to the host server. The client component includes a report software application that is configured to generate a report and provide a GUI on the display. A processor populates the GUI based upon received and processed medical information from the host server component and arranges the medical information in predetermined, inter-related levels. A cursor is provided to allow the user to point to an area of interest in the display and a further level of information pertaining to one or more layers of medical information is viewable by a user when the cursor is pointed over an image on the display.

  • Publication number: 20100298685
    Abstract: A proactive system and method in which levels of glucose are monitored after a meal signal and compared to a safe range. If a monitored glucose level is outside the safe range, a post-prandial vertex of the glucose level is identified and an action is provided to more rapidly return the glucose level to a target level within the safe range than if no action was provided. In another aspect a control parameter in an IDM system is adjusted by determining a performance metric of the system as a function of the levels of glucose and a medication administration signal over a first window of time; and, if the performance metric is outside an expected range, adjusting the control parameter to adjust an amount of medication and to bring the performance metric inside the expected range.
