Analyte monitoring device and methods of use
An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte. The analyte monitor may also be part of a drug delivery system to alter the level of the analyte based on the data obtained using the sensor.
1. A communication device, comprising:
an input unit configured to receive an indication associated with one or more parameters related to a patient condition including a monitored analyte level, the input unit including a radio frequency (RF) receiver configured to receive remotely generated signals associated with the monitored analyte level;
a processor operatively coupled to the input unit, the processor configured to process information related to the received indication, the processor configured to determine an acceleration of the monitored analyte level increase or decrease;
an output unit operatively coupled to the processor and configured to output an output indication based on the processed information; and
an RF transmitter operatively coupled to the processor and configured to wirelessly transmit one or more signals associated with the processed information;
wherein the communication device is configured to enter a sleep mode when the input unit has not been activated for a predetermined period of time such that during the sleep mode, the processor continues to process data while the output unit is not activated.
