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.

First claim

1 .- 14 . (canceled)

15 . A handheld diabetes management device for managing blood glucose test data and continuous glucose monitoring data, comprising:
a port configured to receive a test measurement strip having a sample of blood from a patient; a wireless transceiver; a user interface processor; and a communication processor cooperatively operable with the wireless transceiver to periodically collect continuous glucose measurement data from a continuous glucose monitoring device and detect an error condition related to the continuous glucose measurement data or the collection thereof, wherein the communication processor invokes the user interface processor immediately to report the error condition to the interface processor upon detecting an error condition of a first type but defers reporting the error condition to the user interface processor upon detecting an error condition of a second type different than the first type, wherein the user interface processor is configured to operate in a low power mode, wherein the interface processor enters an active mode upon receipt of the error condition from the communication processor and generates an error notification in response to the error condition received from the communication processor, and wherein the user interface processor consumes electrical power in the active mode at a higher rate than in the low power mode.

16 . The diabetes management device of claim 15 , wherein the first type of error condition includes a status of active safety warnings and any of the following events: a warning threshold is crossed; a recommendation to calibrate state; a communication error in the transceiver or communications processor; loss of communication with continuous glucose monitoring device; and a non-zero status indicative of error from the continuous glucose monitoring device.

17 . The diabetes management device of claim 15 , wherein the second type of error condition includes a status of non-active safety warnings and any of the following events: a recommendation to calibrate; a communication error in the transceiver or communications processor; and a non-zero status indicative of error from the continuous glucose monitoring device.

18 . The diabetes management device of claim 15 , wherein the user interface processor enters an active mode upon receipt of a test measurement strip into the port and initiates a blood glucose measurement of a blood sample on the test measurement strip, wherein the communication processor powers down the wireless transceiver during the blood glucose measurement.

19 . The diabetes management device of claim 15 , wherein the user interface processor sends time offsets and time block limits to the communications processor and the communications processor applies the time offsets and time block limits to the data from the continuous glucose monitoring device.

20 . (canceled)

21 . A diabetes management device for managing blood glucose test data and continuous glucose monitoring data, comprising:
a port residing in the handheld diabetes management device and configured to receive a test strip; a wireless transceiver; a communications processor cooperatively operable with the wireless transceiver to periodically collect glucose measurement data from a continuous glucose monitoring device and detect an error condition related to the continuous glucose measurement data or the collection thereof; and a user interface processor in data communication with the communication processor and operates in an active mode to retrieve and process the glucose measurement data from the communication processor and operates in a low power mode asynchronously from the communications processor; wherein the communication processor wakes up the user interface processor from a low power mode to an active mode in response to detecting an error condition of a first type and defers reporting the error condition to the user interface processor in response to detecting an error condition of a second type different than the first type, such that the user interface processor consumes electrical power in the active mode at a higher rate than the first rate and the user interface processor consumes electrical power in the low power mode at a lower rate than the first rate.

22 . The diabetes management device of claim 21 , wherein communications processor stores the glucose measurement data in a first data storage module, and the user interface processor receives the glucose measurement data from the communications processor and stored the glucose measurement data in a second storage module.

23 . The diabetes management device of claim 21 , wherein when a test strip is inserted in the port, the communication processor operates to turn the wireless transceiver off.

24 . The diabetes management device of claim 21 , wherein the communications processor wakes up the user interface processor from the low power mode when safety warnings are active and a warning threshold is crossed.

25 . The diabetes management device of claim 21 , wherein the communications processor wakes up the user interface processor from the low power mode when safety warnings are active and calibration is recommended.

26 . The diabetes management device of claim 21 , wherein the communications processor wakes up the user interface processor from the low power mode when safety warnings are active and a communication error is detected in the wireless transceiver or the communications processor.

27 . The diabetes management device of claim 21 , wherein the communications processor wakes up the user interface processor from the low power mode when safety warnings are active and a non-zero status indicative of error is received from the continuous glucose monitoring device.

28 . The diabetes management device of claim 21 , wherein the communications processor wakes up the user interface processor from the low power mode when safety warnings are active and communication with continuous glucose monitoring device is lost.

29 . The diabetes management device of claim 21 , wherein the communications processor does not wake up the user interface processor from a sleep mode when safety warnings are not active and any of the following events is detected: recommendation to calibrate; a communication error in the transceiver or communications processor; and a non-zero status indicative of error from the continuous glucose monitoring device.

30 . The diabetes management device of claim 29 , wherein the communications processor stores the detected event and notifies the user interface processor when the user interface processor is in active mode.

31 . The diabetes management device of claim 21 , wherein the user interface processor sends time offsets and time block limits to the communications processor and the communications processor applies the time offsets and time block limits to the data from the continuous glucose monitoring device.
