Patents by Inventor Pavel Vereshchetin

Pavel Vereshchetin has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11497851
    Abstract: A system and a method for management of diabetes are provided. The system includes an infusion pump, glucose sensor, and controller that is programmed to control insulin delivery based upon at least one stored variable. The controller calculates a maximum insulin delivery rate based on the default basal insulin delivery rate, temporary basal insulin delivery rate, extended bolus rate, or a combination thereof.
    Type: Grant

  • Patent number: 10729849
    Abstract: An artificial pancreas system includes a continuous glucose monitoring device, a drug delivery device configured to exchange data with the continuous glucose monitoring device and containing a control algorithm, and possibly a remote controller configured to exchange data with the drug delivery device. The algorithm contains an insulin-glucose model, but is decoupled mathematically from the insulin injected by the user to offset the ingested carbohydrates. The control algorithm is designed to calculate two versions of insulin-on-board-patient-facing insulin-on-board (PFIOB) and system-facing insulin-on-board (SFIOB) to properly parse boluses and inform the system of only the insulin that is intended for high glucose correction, but not carbohydrate offsetting.

  • Patent number: 10583249
    Abstract: A visualization and analysis tool is provided for an insulin delivery system, such as an artificial pancreas, in which insulin is delivered based upon a system algorithm using a pump that is patient controllable in order to adjust insulin delivery relative to a baseline delivery rate; e.g., pre-set basal rate and a sensor for measuring glucose levels. The tool is configured with a controller of the system to detect and log events that are based on differences between actual insulin delivered by the system and the baseline delivery rate. These detected events are metrics that provide information relating to the therapeutic value of the system which, without such metrics, may be overlooked or unnoticed, thereby fostering trust and confidence in the delivery system. In addition, information is provided which may enable further improved glucose control.

  • Patent number: 10154809
    Abstract: An electrochemical biosensor test strip device and compatible meter or processor for determining the amount of an analyte in a liquid sample received from a subject. The device may include: a substrate having a liquid sampling end and an electrical contact end; a circuit disposed in communication with the substrate; a reaction area formed at the liquid sampling end of the substrate; and a lancet having a pointed end and an opposite end, whereby the opposite end of the lancet is disposed in communication with the substrate and located at the reaction area. The device may also include an interface area that may be separate or integrated as part the reaction area (or the reaction area may be integrated with interaction area).
