Abstract
The present invention relates to diagnostic devices incorporating electrode modules and fluidics for performing chemical analyses. The invented devices consist of at least one component sensor formed on an electrode module, the sensor being contained within a fluidic housing. The electrode module is a laminate of a perforated epoxy foil and a photo-formed metal foil with sensor membranes deposited into the perforations. The fluidic housing is a diagnostic card consisting of a plastic card-like body, the at least one component sensor, a sealed chamber defined in the card body for containing a fluid, a fluid conduit for fluidically connecting the chamber with the sensor region, a valve for fluidically connecting the chamber to the fluid conduit, and a delivery structure separate and distinct from the valve for forcing fluid from the chamber and into the fluid conduit.
