Abstract:
1. An electrode module for use in a diagnostic card for sensing at least one component concentration in a fluid sample, comprising a substantially planar insulator layer; and a substantially planar metal conductor layer laminated to the insulator layer; the electrode module having a centrally located sensing region, a peripherally located contacting region and an intermediate heating region located between the sensing and contacting regions and surrounding the sensing region, the insulator layer in the sensing region having a number of throughgoing apertures, a sensor membrane in each aperture for contact with the sample and for electrical contact with the conductor layer, the conductor layer being divided into a corresponding number of conductor elements and a heater contact element electrically insulated from the conductor elements, each conductor element including a conductor path having a sensor end and an opposite contact pad end, the sensor ends being located in the sensing region of the module and below one of the apertures respectively and the contact pad ends being located in the contact region and the conductor path extending from the sensor end in the sensing region, through the heating region to the contact pad end in the contacting region, the heater contact element being located in the heating region between the sensing and contacting regions and electrically insulated from the conductor elements, the heater contact element being shaped to surround the sensing region except for a connecting gap extending between the sensing and contact regions, the conductor paths extending through the connecting gap.
