  • Publication number: 20230368885
    Abstract: A structure, method, and computer program product for a diabetes control system provides, but is not limited thereto, the following: open-loop or closed-loop control of diabetes that adapts to individual physiologic characteristics and to the behavioral profile of each person. An exemplary aspect to this adaptation is biosystem (patient or subject) observation and modular control. Consequently, established is the fundamental architecture and the principal components for a modular system, which may include algorithmic observers of patients' behavior and metabolic state, as well as interacting control modules responsible for basal rate, insulin boluses, and hypoglycemia prevention.

  • Publication number: 20230352185
    Abstract: A method, system, and computer-readable medium are provided for modeling a time-varying representation of the glucose homeostasis of a patient with Type 1 diabetes (T1D) according to a computational model therefor. The model implements a reconstruction of data supporting a glucose time series for the patient, and based on the reconstruction, further implements model personalization and a variability control (VC) signal accounting for insulin sensitivity so as to enable the patient to learn an effect of adjustment to one or more portions of the data. Such knowledge is acquired upon a replay of the reconstruction implementing the adjustment.

  • Publication number: 20230293062
    Abstract: An aspect of an embodiment or partial embodiment of the present invention (or combinations of various embodiments in whole or in part of the present invention) comprises, but not limited thereto, a method and system (and related computer program product) for continually assessing the risk of hypoglycemia for a patient and then determining what action to take based on that risk assessment. A further embodiment results in two outputs: (1) an attenuation factor to be applied to the insulin rate command sent to the pump (either via conventional therapy or via open or closed loop control) and/or (2) a red/yellow/green light hypoglycemia alarm providing to the patient an indication of the risk of hypoglycemia. The two outputs of the CPHS can be used in combination or individually.

  • Publication number: 20220395200
    Abstract: A method, system, and computer-readable medium for providing a real-time estimation of laboratory glycosylated hemoglobin (HbA1c) at one or more intervals. The real-time estimation is conferred as a value of estimated, time variable A1e (eA1c) based on daily continuous glucose monitoring (CGM)-derived time in target range (TIR) (CGM-TIR). The eA1c value is adjusted based on a sole laboratory HbA1c value for an interval preceding an interval corresponding to the eA1c value so as to provide an expected value for a laboratory HbA1c value at the same corresponding interval.

  • Publication number: 20220386965
    Abstract: Embodiment relate to a system for developing a model to classify continuous glucose monitoring (CGM) data. The system includes a processor and computer memory having instructions stored thereon that when executed will cause the processor to determine whether two CGM profiles match based on a similarity of shapes of the two CGM profiles, each CGM profile including a data set of CGM measurements. The processor designates two matching CGM profiles as a CGM profile pair. The processor transforms the CGM profile pair into a motif. The processor labels the motif as a labelled motif based on a clinical characteristic. The processor recursively repeats the determine, designate and transform steps of a CGM profile pairing process until a finite set of motifs is created, which includes the labelled motif as a classified data point. The processor monitor, analyzes, or influences a concentration of glucose levels in a fluid.

  • Patent number: 11355238
    Abstract: A system, computer program product, method and algorithm for evaluation of blood glucose variability—one of the most important parameters of diabetes management. An embodiment of the method may use routine self-monitoring blood glucose (SMBG) data collected over a period of 2-6 weeks, for example, based on a theory of risk analysis of blood glucose data. One aspect may include a method, system and computer program product for computing the Average Daily Risk Range (ADRR)—a measure of overall glucose variability. Another aspect may include a method, system, and computer program product for estimating separately the glucose variability in the hypoglycemic range via a Low BG Index (LBGI) and the glucose variability in the high BG range via High BG Index (HBGI) followed by a combination of the two indices into a single variability display.
