Analyte monitoring device and methods of use

摘要

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.

主权项

1. A receiver unit in an analyte monitoring system, comprising:
a housing; a receiver coupled to the housing, the receiver configured to receive one or more signals related to an analyte level; an input device operatively coupled to the housing, the input device configured to initiate one or more functions of the receiver; and a display unit coupled to the housing, the display unit configured to display an indicator substantially corresponding to the received one or more signals related to the analyte level, where the indicator includes a directional arrow, and further, wherein a position of the displayed directional arrow substantially corresponds to the received one or more signals related to the analyte level;
wherein the receiver is configured to activate the directional arrow indicator upon detection of a predetermined condition associated with the received one or more signals related to the analyte level, the predetermined condition resulting from a comparison of the received one or more signals related to the analyte level to a threshold value and a determination that the comparison results in the received one or more signals related to the analyte level reaching the threshold value; and furtherwherein the receiver unit enters a sleep mode if the input device has not been activated for a predetermined period of time, and the sleep mode allows the receiver to receive information associated with the one or more signals related to the analyte level but not output the information on the display unit.
