COEXISTENCE OF MULTIPLE RADIOS IN A MEDICAL DEVICE

摘要

A handheld diabetes management device having a plurality of communication modules for communicating with a plurality of medical devices via a shared antenna or multiple antennas, where the handheld diabetes management device includes a first communication module, a second communication module, and an arbitration module. The first communication module 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. The second communication module selectively communicates in the first frequency band with a continuous glucose monitor external to the handheld diabetes management device via a second antenna or the first antenna using a second wireless communication protocol. The arbitration module grants permission to communicate to the first communication module and denies permission to communicate to the second communication module when the first and second communication modules request permission to communicate concurrently.
