Secure Data Exchange in Glucose Monitors

A method for retrieving analyte data from a glucose monitoring system without needing a wired connection or user credentials involves creating an association between patient records in the monitoring system and an electronic medical records (EMR) system. This association enables the EMR system to request new glucose data from the monitoring system, which then sends the data automatically without requiring user intervention or authentication.

Optimizing RF communication in medical devices, such as glucose monitors, enhances data transmission reliability and efficiency. The technique utilizes proximity commands to trigger specific functions on the device without the need to transmit full data packets. This separation of urgent and non-urgent data minimizes transmission time. The device positions itself within range, sends predefined commands, and receives responses. This approach allows tasks like sensor calibration to be segmented and transmitted separately while critical data is sent immediately.

Optimizing RF communication in medical devices like glucose monitors to improve data transmission efficiency. The optimization involves using close proximity commands to trigger specific functions on the device instead of sending all data at once. When the transmitter is close to the receiver, it sends predefined commands to request critical data like real-time glucose levels. This allows the transmitter to go into sleep mode between requests, conserving power. It also enables segmenting non-urgent data into packets and transmitting them separately. This separates time-sensitive critical data from less urgent data to reduce transmission time constraints. The close proximity commands are predefined and the receiver responds with requested data.

A system for managing glucose levels facilitates the transfer of sensor context information between disposable devices. The system includes a glucose sensor, electronics, and a receiving device. External disposable glucometers can communicate with both the sensor and the receiving device. When a user replaces a disposable glucometer, the system packages the sensor context information and transfers it to the new device. This ensures continuity of sensor performance without requiring user calibration or device setup when switching disposables.

Transmitting and receiving biometric information between a sensor and a device in a continuous monitoring system reduces the need to verify data receipt at every regular interval. Instead, the system checks for unreceived data only at extended intervals and selectively requests missing data when necessary. This approach minimizes processing demands and energy consumption compared to constant checking.

A system for augmenting wearable continuous glucose monitoring (CGM) devices with additional physiological data to provide more context and insights into glucose trends. The system involves using a secondary wearable device that can collect additional data like heart rate, sweat, or skin temperature. This secondary wearable is communicably coupled to the CGM device and both devices transmit their data to a central hub. The hub combines the CGM glucose data with the additional physiological data to provide a more complete picture of the user's health. This allows the hub to detect events like exercise or meals that may not be immediately apparent from glucose alone, as well as correlations between glucose and other physiological factors. The secondary wearable can have form factors that complement the CGM device to minimize size and complexity.

Notification method for continuous glucose monitoring systems that alert users when sensor module batteries are low and prevent reuse of expired sensors. The method involves a central device connecting to the sensor, calculating the remaining battery life, and notifying the user. If communication is lost, the central device verifies if the sensor truly failed vs just disconnected. If confirmed failed, it notifies to replace. This prevents users from mistakenly using expired sensors.

It involves using an image recognition code on the device to quickly connect it to a communication terminal. The code contains the device identifier and pin code. The terminal searches for devices using the identifier and then connects using the retrieved PIN code from the code. If the device is lost, the terminal requests the server to send the code.

Connecting a continuous glucose monitor to a communication device like a smartphone in a way that prevents mixing of data from different users and ensures proper functionality when reconnecting. The method involves checking if the monitor is new or previously used, verifying user identity, and checking if the monitor still has usable life left. If the monitor is reused, it connects without extra steps. If not, it terminates the connection to prevent mixing data. When reconnecting, it checks if the monitor is still usable and if the user is still authorized. This prevents using expired sensors or reusing ones by others.

A system to improve continuous glucose monitoring by optimizing data transfer between a continuous glucose meter (CGM) and a receiver device like a smartphone. The CGM can still transmit glucose data when disconnected from the receiver by sending a connection request with event information. If the receiver identifies an event like low glucose, it responds to reconnect and receive the CGM data immediately. This allows the CGM to conserve power by reducing transmissions when connected, but still provide urgent glucose alerts. The receiver adjusts connection request intervals based on events to balance efficiency and responsiveness.
