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.

Diabetes manager for glucose testing and continuous glucose monitoring

A hand-held device for measuring an analyte concentration in a sample of a body liquid includes a display means for displaying measured values; a measured-value storage for storing measured values; a measuring unit for generating measured values through measurements of the analyte concentration; a clock; a control unit for generating measured value datasets, each containing a measured value supplied by the measuring unit as well as the date and hour of the measurement by which the measured value was obtained, and for writing them into the measured-value storage; and operating elements that can be actuated by the user to set the clock, in which case the control unit will generate a time-correction dataset indicating the amount and direction of the setting effected. The control unit writes time-correction datasets into the measured-value storage so that a chronologically ordered sequence is generated containing time-correction datasets and measured value datasets.

Method of measuring an analyte concentration in a sample of a body liquid

The invention concerns an array and a method for dosing a hormone regulating the blood glucose, especially insulin, of a diabetic patient. In order to improve the administration of the hormone, the invention provides the following characteristic combination: a first sensor for measuring tissue glucose level; a controller having as an input the measured tissue glucose level from the first sensor, the controller having a control algorithm to determine an amount of hormone to be dosed based upon the measured tissue glucose level; a hormone dosing unit connected to the controller and automatically administering a hormone dose based upon a signal received from the controller; a second sensor for measuring an influencing patient variable; a pilot control device connected to the second sensor, the pilot control device connected to and forming a circuit with the controller, the pilot control device acting on the controller in accordance with the influencing patient variable that is measured by the second sensor, whereby the pilot control device reduces dead time of the controller.
