CONTINUOUS GLUCOSE MONITORING INJECTION DEVICE
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.

8 . The device of claim 6 , wherein the continuous glucose monitoring information comprises a most recent blood glucose value received from the one or more external devices, wherein the processor is configured to determine the appropriate bolus dose for the patient based on the most recent blood glucose value received from the one or more external devices.
9 . The device of claim 1 , wherein the delivery device is configured to prime the cartridge and needle prior to medicament delivery.
10 . The device of claim 9 , wherein the processor is configured to initiate a notification that the delivery device is prepared for injection after priming of the cartridge and needle.
11 . The device of claim 1 , further comprising a blood glucose monitoring sensor and blood glucose monitoring test strip, wherein the blood glucose monitoring sensor is configured to measure blood glucose from the blood glucose monitoring test strip.
12 . The device of claim 11 , wherein the processor is configured to determine an appropriate bolus dose for the patient based on the measured blood glucose.
13 . The device of claim 1 , wherein the one or more external devices comprise one or more continuous glucose monitors.
14 . The device of claim 1 , wherein the continuous glucose monitoring information comprises blood glucose concentration measurement data.
15 . The device of claim 1 , wherein the processor is configured to generate a plot of blood glucose history based on the continuous glucose monitoring information.
16 . The device of claim 1 , wherein the patient status comprises one or more of a high or low glucose reading, a requirement of an insulin dose, a required insulin dosage amount, and a requirement of emergency medical treatment.
17 . A method in an electronic delivery device for delivering medicament to a patient, comprising:
receiving continuous glucose monitoring information from one or more external devices;
setting a bolus dosage amount based on the continuous glucose monitoring information;
activating a user interface on the delivery device or an external device to display a notification; and
delivering medicament from a cartridge of the delivery device to the patient through a needle.
18 . The method of claim 17 , wherein the notification comprises the bolus dosage amount.
19 . The method of claim 17 , further comprising measuring blood glucose from a blood glucose monitoring test strip using a blood glucose monitoring sensor within the electronic delivery device.
