AUTONOMOUS, AMBULATORY ANALYTE MONITOR OR DRUG DELIVERY DEVICE

摘要

The invention relates to analyte monitoring/drug (pharmaceutical agent) delivery device (10). The invention is suited for monitoring various blood constituents such as glucose. The device has a housing (12) that at least partially encloses a plurality of microneedles (14) disposed on a carrier (1 6) and an electronics portion (18). Each microneedle (14) is in fluid communication with a corresponding microchannel (20). Each microneedle (14) is individually addressable. That is, each microneedle (14) can be extended and retracted individually via an actuator (22). The electronics portion (18) includes a processor (30) and associated circuitry (e.g., memory, supporting electronics and the like), a motor (32) or the like, a sensor (34), a power supply (e.g., battery) (36) and optionally an interface (38). In general, th e processor (30) controls the operation of the device (10) and is data communication with the actuator (22), motor (34) and interface.
