Abstract

A handheld diabetes management device for managing blood glucose test data and continuous glucose monitoring data includes a port configured to receive a test strip, a wireless transceiver, a communications processor, and a user interface processor. The communications processor communicates with the wireless transceiver to periodically collect glucose measurement data from a continuous glucose monitoring device and to store the glucose measurement data in a first data storage module. The communications processor is operable to consume electrical power at a first rate. The user interface processor communicates with the communication processor to receive the glucose measurement data and operable to display the glucose measurement data on the device. The communications processor operates asynchronously from operation of the user interface processor to collect the glucose measurement data and the user interface processor operates to consume electrical power at a second rate that is higher than the first rate.
