Continuous glucose monitoring injection device
View Patent ↗An electronic insulin delivery device receives glucose data from a glucose monitor and sets a bolus dose amount. The device may take the form of an insulin pen with automatic priming and accurate dosing provided by a motor in connection with an encoder. The device may communicate with and be controlled by a smart phone device. The smart phone device provides a user interface to receive user data including patient weight, insulin to carbohydrate ratio and exercise factor, and to send instructions to the device, including dose amount. The dose amount is determined taking into account glucose level and trend, and other factors. The delivery device may be in continuous communication with the glucose monitor and smart phone to provide for near real-time adjustments in glucose treatment. Glucose data, insulin injection data, and other relevant data may be stored and accessible to interested parties.
