  • Patent number: 12285589
    Abstract: An insulin monitoring system includes one or more processors, one or more computer-readable storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors. The program instructions include: first program instructions to track, in real time, the amount of insulin active in a patient; second program instructions to calculate the amount of insulin need of the patient by tracking the patient's metabolic states; third program instructions to compare the insulin active in the patient with the insulin need of the patient; and fourth program instructions to determine an insulin fault level based on the comparison.

  • Publication number: 20250090052
    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: 20250072793
    Abstract: Embodiments relate to a system for processing glucose data by efficient glucose database management. The system includes a physical data store containing glucose measurement data and a representation for at least one cluster of the glucose measurement data, wherein the representation approximates a glycemic profile vector array for a cluster of multiple glucose profiles segmented by plural time ranges. The system includes a processor and computer memory configured with instructions stored thereon that when executed will cause the processor to: 1) receive glucose measurements; 2) convert the glucose measurements into vectorial form; 3) search the physical data store by comparing a newly received glucose measurement to a centroid of a cluster using a similarity metric; 3) classify the newly received glucose measurement with a cluster having a matched similarity metric based on the comparing; and 4) ascribe a treatment to the newly received glucose measurement.

  • Publication number: 20240293047
    Abstract: Provided are a method, system and computer-readable storage medium for quantitative physiological assessment and prediction of clinical subtypes of glucose metabolism disorders, including but not limited to, Type 1 diabetes, obesity, pre-diabetes, gestational diabetes, or variants of Type 2 diabetes. The method allows a virtual population of in silico entities to be created, reproducing faithfully the clinical subtype distributions observed in vivo. Potential applications of this method may include, but are not limited to: (a) enabling in silico experiments assessing and/or predicting, for a real patient, treatment or intervention outcomes for a given population/clinical-subtype level; (b) pre-clinical testing of properties of new medications; (c) augmenting limited clinical trial data with in silico experiments to an extent that the domain of their validity and test corner cases may not be observed in vivo.

  • Patent number: 11842817
    Abstract: A method, system and computer readable medium for tracking changes in average glycemia in diabetes is based on a conceptually new approach to the retrieval of SMBG data. Using the understanding of HbA1c fluctuation as the measurable effect of the action of an underlying dynamical system, SMBG provides occasional glimpses at the state of this system and, using these measurements, the hidden underlying system trajectory can be reconstructed for individual diabetes patients. Using compartmental modeling a new two-step algorithm is provided that includes: (i) real-time estimate of HbA1c from fasting glucose readings, updated with any new incoming fasting SMBG data point(s), and (ii) initialization and calibration of the estimated HbA1c trace with daily SMBG profiles obtained periodically. The estimation of these profiles includes a factorial model capturing daily BG variability within two latent factors.
