EEG Monitor Insulin Delivery Hypoglycemia Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current systems for managing blood glucose levels in diabetes patients lack a direct link between EEG monitoring and insulin delivery, preventing timely intervention in hypoglycemia.
Innovation Solution
A system that uses an EEG monitor to detect impending hypoglycemia and send a warning signal to an insulin delivery device, restricting insulin delivery and alerting the user or caregiver, while ensuring the EEG monitor is functioning correctly and providing continuous glucose monitoring data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If EEG monitoring is combined with insulin delivery device, then the ability to detect upcoming hypoglycemia is improved, but the device complexity increases
Solution Approach 1:
The patent combines EEG monitoring functionality with an insulin delivery device into an integrated system. The EEG sensor, processor, and insulin pump work together as a unified system, allowing the device to monitor brain activity patterns indicative of hypoglycemia and automatically respond by adjusting insulin delivery, thereby improving detection reliability while managing complexity through integration.
Solution Approach 2:
The insulin delivery device is enhanced with multiple functions: it not only delivers insulin but also monitors EEG signals, detects hypoglycemic episodes, and automatically adjusts delivery based on neurological state. This multi-functionality allows a single device to perform both traditional insulin delivery and neurological monitoring, improving detection capability without proportionally increasing overall system complexity.
2Reliability
If automatic restriction of insulin delivery is implemented, then safety is improved, but the device complexity increases
Solution Approach 1:
The system implements a feedback loop where EEG signals are continuously monitored, analyzed for hypoglycemia indicators, and used to automatically adjust insulin delivery in real-time. When the EEG processor detects patterns associated with upcoming hypoglycemia, it sends a signal to restrict insulin delivery, creating a closed-loop control system that enhances safety through automatic response to physiological changes.
Solution Approach 2:
The system performs preliminary action by detecting EEG patterns that precede hypoglycemic episodes and restricting insulin delivery before actual hypoglycemia occurs. This proactive approach allows the system to prevent low blood sugar events rather than merely responding to them, improving safety by anticipating and preventing adverse physiological states.
3Measurement precision
If EEG monitor continuously monitors brain activity, then detection precision is improved, but energy consumption increases
Solution Approach 1:
The EEG monitoring system operates by periodically analyzing brain activity signals for hypoglycemia indicators rather than continuously processing all data at full capacity. The system monitors EEG signals continuously but performs detailed analysis only when patterns suggestive of hypoglycemia are detected, allowing for high detection precision while reducing overall energy consumption through selective, event-driven processing.

AI summary
A system for adjusting blood glucose level including an insulin delivery device configured to release insulin into the body of a person, and an EEG monitor having an EEG sensing part including EEG electrodes. The EEG monitor can be arranged in the ear region of the person with the EEG sensing part arranged subcutaneously at the scalp or arranged in the ear canal. The EEG monitor includes an EEG signal processor arranged at the ear and adapted for identifying onset of hypoglycemia. The system further includes a wireless link between the EEG monitor and the insulin delivery device. The EEG monitor is configured to submit a warning signal to the insulin delivery device if an upcoming onset of hypoglycemia is identified. The warning message will cause the insulin delivery device to restrict insulin delivery for a predetermined time, and a warning is provided to the person or to a caregiver.
