Patent ID: 8588687

Claim:
A handheld diabetes management device that arbitrates priority among multiple communication modules having a shared antenna for communicating with a plurality of medical devices, the handheld diabetes management device comprising: a blood glucose measuring module that selectively measures blood glucose in a blood sample; a first communication module that selectively communicates in a first frequency band with an insulin infusion pump external to the handheld diabetes management device via a first antenna using a first wireless communication protocol; a second communication module that selectively communicates in the first frequency band with a continuous glucose monitor external to the handheld diabetes management device via the first antenna using a second wireless communication protocol; and an arbitration module that receives signals from the first and second communication modules for concurrent communication with the insulin infusion pump and the continuous glucose monitor, respectively, identifies the insulin infusion pump and the continuous glucose monitor as the source or destination of the signals, determines that the insulin infusion pump has a higher priority than the continuous glucose monitor, and grants permission to communicate to the first communication module, and denies permission to communicate to the second communication module; and a power management module that deactivates the first and second communication modules while the blood glucose measuring module measures the blood glucose in the blood sample.
