Abstract
An automated blood glucose control system is configured to generate a backup therapy protocol comprising insulin therapy instructions derived from autonomously determined doses of insulin. The system generates a dose control signal using a control algorithm configured to autonomously determine doses of insulin to be infused into a subject for the purpose of controlling blood glucose of the subject based at least in part on a glucose level signal received from a glucose sensor. The system can track insulin therapy administered to the subject over a tracking period, including storing an indication of the autonomously determined doses of insulin delivered to the subject as basal insulin, as correction boluses of insulin, or as mealtime boluses of insulin. The system can generate a backup injection therapy protocol or a backup pump therapy protocol with insulin therapy instructions based at least in part on the insulin therapy administered to the subject over the tracking period.
Core Innovation
The invention is an automated glucose level control system that generates a backup therapy protocol comprising insulin therapy dosing recommendations derived from autonomously determined doses of insulin. The system includes a medicament delivery interface configured to connect to a medicament pump for infusing medicament into a subject, and a hardware processor that executes stored computer-executable instructions.
The system tracks insulin therapy administered to the subject over a tracking period by storing indications of autonomously determined doses delivered as correction boluses of insulin or as basal doses of insulin. From the tracked autonomously determined insulin doses, the system generates the backup therapy protocol comprising at least one of a plurality of backup therapy dosing recommendations.
The plurality includes a correction dosing recommendation comprising a correction factor based on at least some of the correction boluses administered during the tracking period, and a basal dosing recommendation comprising a basal rate based on at least some of the basal doses administered during the tracking period. The backup therapy protocol is output for use when the automated glucose level control system is not providing therapy to the subject.
Claims Coverage
The document contains two independent claims. Across these independent claims, the core inventive features are structured around autonomously determined insulin dose tracking and generating a backup therapy protocol that includes both a correction dosing recommendation based on a correction factor and a basal dosing recommendation based on a basal rate, with the protocol output for use when automated therapy is not provided.
Track autonomously determined insulin dose history for correction boluses and basal doses
Tracking insulin therapy administered to the subject over a tracking period by storing an indication of autonomously determined doses of insulin delivered to the subject as correction boluses of insulin or as basal doses of insulin.
Generate backup therapy protocol with correction dosing recommendation based on correction factor
Generating the backup therapy protocol comprising at least one of a plurality of backup therapy dosing recommendations, wherein the plurality of backup therapy dosing recommendations comprises a correction dosing recommendation comprising a correction factor based on at least some of the correction boluses of insulin administered during the tracking period.
Generate backup therapy protocol with basal dosing recommendation based on basal rate
Generating the backup therapy protocol comprising at least one of a plurality of backup therapy dosing recommendations, wherein the plurality of backup therapy dosing recommendations comprises a basal dosing recommendation comprising a basal rate based on at least some of the basal doses of insulin administered during the tracking period.
Output backup therapy protocol for use when automated glucose control is not providing therapy
Output the backup therapy protocol as determined by the automated glucose level control system for the purpose of being used when the automated glucose level control system is not providing therapy to the subject.
Both independent claims converge on the same inventive structure: the system/method tracks autonomously determined insulin doses as correction boluses and basal doses over a tracking period, generates a backup therapy protocol that includes a correction dosing recommendation with a correction factor and a basal dosing recommendation with a basal rate, and outputs the protocol for use when the automated glucose level control system is not providing therapy.
