  • Intelligent therapy recommendation algorithm and method of using the same
    Patent number: 9056165
    Abstract: An algorithm and method of making intelligent therapy recommendations for insulin pump parameters is described. The pump parameters include basal rates, carbohydrate-to-insulin ratios (CIR), and insulin sensitivity factors (ISF). A determination of whether a therapy recommendation should be made is based on comparing an updated recommended change with a threshold. The updated recommended change to the pump parameter is made based on a previous recommended change to the pump parameter and the difference between a current blood glucose value and a targeted blood glucose level. The algorithm and method confirms the therapy recommendation is within safety parameters before displaying the therapy recommendation.

  • CLOSED-LOOP CONTROL OF GLUCOSE ACCORDING TO A PREDICTED BLOOD GLUCOSE TRAJECTORY
    Publication number: 20150157794
    Abstract: Presented here are techniques for controlling glucose levels of a patient based on predicted time to a target glucose level. One methodology predicts a trajectory of the blood glucose level based on past observations of the blood glucose level, determines a cost expression based on the trajectory, and affects a future command to an infusion pump to affect a cost value according to the cost expression. Another methodology defines a target blood glucose concentration level for the patient, observes a current blood glucose concentration for the patient based on signals received from a blood-glucose sensor, and predicts a duration of time for the patient's blood glucose concentration to reach the target blood glucose concentration level based on the observed current blood glucose concentration.

  • Occlusion detection for a fluid infusion device
    Patent number: 9050406
    Abstract: A device for delivering fluid to a user includes a housing, a drive motor assembly in the housing, a force sensor, and an electronics module. The drive motor assembly regulates delivery of fluid by actuating a piston of a fluid reservoir, and the force sensor generates output levels in response to force imparted thereto during, for example, fluid delivery operations. The electronics module processes the output levels of the force sensor to assess the operating health of the force sensor, to check for occlusions in the fluid delivery path, and to monitor the seating status of the fluid reservoir.
