Analyte monitoring device and methods of use
First Claim
1. A glucose monitoring device, comprising:
- a glucose sensor, at least a portion of which is adapted for implantation and contact with bodily fluid, the glucose sensor producing a signal representative of a level of glucose in the bodily fluid; and
a transmitter coupled to the glucose sensor so that the transmitter converts the signal representative of the level of glucose in the bodily fluid into a digital signal representing the level of glucose in the bodily fluid, assembles a plurality of data words into a data message, at least one of the data words containing data derived from the digital signal representing the level of glucose in the bodily fluid, each of the data words comprising a set of bits, wherein for at least two of the data words, the set of bits are organized into a set of data bits and a set of error correction bits, and transmits the plurality of data words in an interleaving sequence, wherein the interleaving sequence includes transmitting a first bit in each of the set of bits of each of the data words of the data message followed by transmitting a second bit in each of the set of bits of each of the data words of the data message until the assembled plurality of data words are transmitted.

Abstract
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.

13. A method comprising:
-
collecting, using a glucose sensor, an analog signal representing a level of glucose in a bodily fluid; converting, using a transmitter, the analog signal into a digital signal representing the level of glucose in the bodily fluid; assembling, using the transmitter, a plurality of data words into a data message, at least one of the data words containing data derived from the digital signal representing the level of glucose in the bodily fluid, each of the data words comprising a set of bits, wherein for at least two of the data words, the set of bits are organized into a set of data bits and a set of error correction bits; and transmitting, using the transmitter, the data message, such that the plurality of data words assembled into the data message are transmitted in an interleaving sequence, wherein the interleaving sequence includes transmitting a first bit in each of the set of bits of each of the data words of the data message followed by transmitting a second bit in each of the set of bits of each of the data words of the data message until the assembled plurality of data words are transmitted. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
