Patent ID: 7291497

Claim:
A medical device comprising a disposable patch capable of detecting an analyte of unknown concentration in a bodily fluid, said patch comprising: at least one microneedle capable of obtaining a sample of a bodily fluid; a buffer reservoir; a microchannel having at least a first inlet, a second inlet, and a microarray attached onto the microchannel, said microarray comprising at least one bioactive agent, wherein the first inlet is in fluid communication with the at least one microneedle and channels a flow of bodily fluid into the microchannel, and wherein the second inlet channels a flow of buffer from said buffer reservoir into the microchannel, such that the analyte in the bodily fluid diffuses into the flow of buffer to effect an interaction between the bioactive agent and the analyte therein; a microarray scanning device to detect the interaction between the bioactive agent and the analyte in the bodily fluid; and an interface device capable of facilitating communications between said microarray scanning device and a biometric recognition device.
