Flexible patch for fluid delivery and monitoring body analytes
First Claim
1. A method for measuring analyte utilizing a body analyte monitoring system, the body analyte monitoring system having a flexible patch, a first analyte sensor, a second analyte sensor, a power source, and a controller, wherein a plurality of sensor insertion sites are on the flexible patch, and wherein the flexible patch is configured to be worn on a skin surface and to receive one or more analyte sensors at one or more of the plurality of sensor insertion sites, the method comprising:
- inserting the first analyte sensor into one of the plurality of predefined sensor insertion sites through the skin surface and in contact with fluid under the skin surface at the one of the plurality of predefined sensor insertion sites;
removing the first analyte sensor from the one of the plurality of predefined sensor insertion sites after the lifetime of the first analyte sensor has expired while the flexible patch is retained on the skin surface;
inserting the second analyte sensor in another one of the plurality of predefined sensor insertion sites through the skin surface and in contact with the fluid under the skin surface at the another one of the plurality of predefined sensor insertion sites after the first analyte sensor is removed from the one of the predefined sensor insertion sites and while the flexible patch is retained on the skin surface; and
communicating signals from the second analyte sensor to the controller, wherein the controller is powered by the power source.

Abstract
A wearable, conductive textile patch is provided that may include any of a number of features for monitoring body analytes and/or delivering fluids to a body. In one embodiment of the invention, a single, patch-mounted system monitors glucose levels of a diabetic person and provides appropriate doses of insulin in response to the glucose measurements. A hand-held user interface can be provided for wirelessly controlling the system and/or receiving information from it. Conductive pathways can be formed in the fabric of the patch. Components that can be integrated into the flexible patch include a power source, controller, transmitter, antenna, temperature and other sensors, fluid pump, infusion set, electrical pathways, switches, controls, electrodes, connectors, resistors and other circuit elements. Such components can be embedded, interwoven or coated on to the flexible patch instead of or in addition to surface mounting. Methods associated with use of the flexible patch system are also covered.
