摘要: The present invention relates to planar electrochemical sensors with membrane coatings used to perform chemical analyses. The object of this invention is to provide unit-use disposable sensors of very simple and inexpensive construction, preferably with only a single membrane coating on an electrode. The invented devices are potentiometric salt-bridge reference electrodes and dissolved gas sensors constructed with a heterogeneous membrane coating of a conductor. The heterogeneous membrane, which is an intimate admixture of a hydrophobic and a hydrophilic compartment, concurrently supports constrained transport of non-volatile species through its hydrophilic compartment and rapid gas and water vapor transport through its hydrophobic compartment.

摘要: Planar devices incorporating electrodes for performing chemical analyses are disclosed. The device include an electrode module in a fluidic housing. The electrode module includes a carrier module and at least one electrode thereon. More specifically, the electrode module includes a planar carrier module made of laminate of a metal layer and an insulator layer, which metal layer is divided into at least two metal conductor elements; and at least one electrode formed directly on the carrier module and including a membrane element for imparting chemical sensitivity to the electrode, the membrane element being applied to the insulator layer to be in electrical contact with one of the metal conductor elements through the insulator layer. The insulator layer preferably has die cut perforations through which the membrane element extends into electrical contact with the conductor layer. In the most economical embodiment, the carrier module is a common chip carrier according to ISO 7816-2. The devices of cheaper construction than prior art chemical analysis chips, especially since they are of much simplified construction and of standardized format which allows the use of readily available low cost components.

摘要: Devices for cost-effectively performing in-vitro diagnostic chemical analyses at multiple distributed locations within a medical institution are disclosed. One object of this invention is to provide a network of distributed sensory devices that acquire sensor signals from blood specimens and deliver those signals through a connection to a central location for analysis by a general-purpose computer and generation of an analysis result. The analysis result is then sent to numerous locations on a network for display, including also possibly back to the location of signal acquisition. Cost-effective mobile sensing devices are also sdisclosed. The present system includes blood-sensor signal acquisition devices distributed throughout the hospital. The sensory signal-acquisition devices are card readers that acquire raw sensory signals from diagnostic cards inserted therein. These diagnostic cards are smart card-like devices modified for blood collection that contain sensory elements such as electrodes adapted to provide a raw sensory signal. The signal acquisition devices are modified smart card readers, which acquire the raw sensory data from an inserted smart card through a standardized contact arrangement and provide the raw data to data processing devices such as data acquisition cards. The system includes multiple remote ports for acquiring blood sensor signals. One or more card reader, when connected to a mobile general-purpose computer, can be converted into a complete mobile blood analyzer.

摘要: Devices with electrokinetic elements are disclosed as well as their method of microfabrication for use in micro-scale analysis, mixture separation and reaction. The devices consist of solid hydrophilic-matrix films (2) that have been microfabricated into a variety of micro-scale structures. These structures include hydrophilic-matrix conductors (2) for electrokinetic species transport and separation. They also include hydrophilic-matrix cladding containing chemical species adjacent to either an open conduit or a hydrophilic matrix conductor. Also described are other integrated microstructures consisting of hydrophilic-matrix materials (2) such as micro-reaction zones for retaining chemical species for on-chip chemical reactions and integrated detection structures for on-chip species detection. In general, a hydrophilic matrix on a substrate (1) functions as a conductor that is covered by an electrically insulating, preferably water permeable material (3).
