Glucose Monitoring Sensors with Dormant RF Hypoglycemia Alerts
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing analyte monitoring systems fail to provide timely and efficient notifications for adverse physiological conditions such as hypoglycemic conditions, requiring user-initiated data communication that may delay critical interventions.
Innovation Solution
In vivo analyte monitoring systems with integrated sensor electronics that autonomously detect adverse conditions like hypoglycemia, using RF communication to immediately notify users through a separate RF module, while conserving power by dormant communication until a condition is confirmed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If user-initiated data communication is used to conserve power, then power consumption is reduced, but notification timeliness deteriorates
Solution Approach 1:
The communication module dynamically switches between dormant state and active transmission state based on detected adverse conditions. During normal operation, the module remains dormant to conserve power. When an adverse condition is detected, the module activates to transmit notifications immediately, thus resolving the contradiction between power conservation and notification timeliness.
Solution Approach 2:
The sensor electronics autonomously detect adverse conditions and trigger notifications without requiring user initiation. The system self-manages the communication activation based on internal condition detection, eliminating the need for user-initiated communication while maintaining power efficiency through selective activation.
2Loss of time
If continuous data transmission is implemented to ensure timely notifications, then notification timeliness is improved, but power consumption increases
Solution Approach 1:
Instead of continuous transmission, the system employs periodic checking of adverse conditions with transmission occurring only when conditions warrant notification. The communication module activates periodically to check for adverse conditions and transmits only when necessary, reducing overall power consumption while maintaining timely notification capability.
Solution Approach 2:
The system extracts and transmits only the critical information (adverse condition notifications) rather than continuously transmitting all sensor data. By separating the notification function from continuous data transmission, the system achieves timely notification for critical events while minimizing power consumption by transmitting data only when adverse conditions are present.
3Reliability
If RF communication module is activated continuously to ensure immediate notification, then notification reliability is improved, but device complexity increases
Solution Approach 1:
The RF communication module transitions between dormant and active states based on detected adverse conditions. This dynamic state management ensures reliable notification transmission when needed while simplifying the operational complexity by maintaining a dormant state during normal operation, thus resolving the contradiction between reliability and device complexity.
4Loss of time
If sensor electronics autonomously detect and transmit notifications, then notification timeliness is improved, but device complexity increases
Solution Approach 1:
The sensor electronics autonomously detect adverse conditions and trigger notifications without external user initiation. This self-service capability eliminates the need for user intervention, ensuring timely notifications while managing complexity through integrated autonomous detection and communication triggering within the sensor electronics.

AI summary
Methods, devices, systems, and kits are provided that buffer the time spaced glucose signals in a memory, and when a request for real time glucose level information is detected, transmit the buffered glucose signals and real time monitored glucose level information to a remotely located device, process a subset of the received glucose signals to identify a predetermined number of consecutive glucose data points indicating an adverse condition such as an impending hypoglycemic condition, confirm the adverse condition based on comparison of the predetermined number of consecutive glucose data points to a stored glucose data profile associated with the adverse condition, where confirming the adverse condition includes generating a notification signal when the impending hypoglycemic condition is confirmed, and activate a radio frequency (RF) communication module to wirelessly transmit the generated notification signal to the remotely located device only when the notification signal is generated.
