Patent ID: 7824529

Claim:
An electrode module for use in a diagnostic device for performing chemical analysis of a species in a sample fluid and for electrical contact with a contacting element of a connector device, comprising a chip carrier module made of a planar laminated bi-layer of a metal layer and an insulator layer, the insulator layer having opposing first and second sides, the metal layer being located on the first side, forming a lowermost surface of the module and being divided into at least two conductor elements; and a membrane element located on the opposite, second side of the insulator layer, the membrane element being in electrical contact with one of the conductor elements through the insulator layer and together with the one conductor element forming an electrode, the membrane element being configured to contact the sample fluid; the membrane element being made of electrochemical material for imparting chemical sensitivity to the electrode and for developing an electrical signal at the electrode when the species comes into contact with the membrane element; the electrode module having an insulator side and a conductor element side and being configured to permit simultaneous electrical and sample fluid contact with the electrode through physical, electrical contact of the contacting element with the one conductor element on the lowermost surface of the electrode module and simultaneous sample fluid contact with the membrane element on the insulator side of the electrode module.
