Abstract

A patient monitoring network pertaining to blood glucose and other analyte measurements includes wireless blood glucose or other analyte measuring devices and a networked computer or server. Each monitoring device is associated with a patient and is configured to measure the glucose level or other analyte from a given blood sample via inserted test strips, transmit the measurements to the networked computer, and display received messages. The blood glucose monitoring device includes means for substantially reducing factors that could affect the glucose measurement such as thermal and RF interference.

Claims

1. A handheld blood glucose monitoring device comprising:

a glucose sensing subsystem configured to measure a blood glucose level in a blood sample;

a temperature sensor configured to provide a temperature measurement during the measurement of the blood glucose level;

a radio transceiver subsystem electrically isolated from the glucose sensing subsystem and configured to receive the measured blood glucose level from the glucose sensing subsystem, and to transmit the measured blood glucose level over a wireless communications link; and

a display configured to display the measured blood glucose level,

wherein the radio transceiver subsystem includes a microcontroller configured to monitor and control the amount of heat produced by one or more components within the radio transceiver subsystem.

2. The device of claim 1, further comprising an RF shielding structure around at least a portion of the glucose sensing subsystem.

3. The device of claim 1, wherein the microcontroller is further configured to deactivate RF transmission from the radio transceiver subsystem when the glucose sensing subsystem is measuring the blood glucose level.

a display configured to display the measured analyte level,

wherein the radio transceiver subsystem includes a microcontroller configured to monitor and control the amount of heat produced by one or more components within the radio transceiver subsystem.

6. The device of claim 5, further comprising an RF shielding structure around at least a portion of the analyte sensing subsystem.

7. The device of claim 5, wherein the microcontroller is further configured to deactivate RF transmission from the radio transceiver subsystem when the analyte sensing subsystem is measuring the analyte level.
