Patent ID: 8920401

Claim:
An integrated diabetes management system for selectively switching between automated and fail-safe modes, the system comprising: a glucose sensor, wherein the glucose sensor is configured to substantially continuously measure glucose concentration in a host for a period exceeding one hour, and to output a data stream, including one or more sensor data points; and a processor module operably connected to the glucose sensor, wherein the processor module is configured to receive the data stream, to calculate a therapy comprising instructions for administration of a medicament, and to send the instructions to a medicament delivery device, wherein the processor module is configured to operate the integrated system in an automated mode unless a fail-safe mode is triggered, wherein the automated mode does not require user interaction to send the instructions to the medicament delivery device, wherein in the fail-safe mode, the processor module is configured to prompt the host for input before sending the instructions to the medicament delivery device, and wherein the fail-safe mode is automatically triggered responsive to a predetermined fail-safe condition.
