摘要： A device for measuring blood coagulation time is formed from a first substrate; a second substrate; a spacer layer disposed between the first and second substrates, said spacer layer having an opening formed therein defining a sample receiving chamber, a vented sink chamber, and an elongated reservoir forming a conduit for liquid movement between the sample receiving chamber and the sink chamber; a first electrode disposed on the first substrate, said first electrode being exposed in the reservoir portion through a first opening in the spacer layer; and a second electrode disposed on the second substrate, said second electrode being exposed in the reservoir portion through a second opening in the spacer layer. The device of the invention is used in combination with an apparatus that is connected to the first and second electrodes for measuring current flow between the first and second electrodes. Changes in observed current are indicative of flow through the device, and a cessation of flow indicates coagulation.

摘要： A lancet cartridge has a U-shaped support with a pair of anchor portions, a base portion, and a pair of deformable leg portions connecting the anchor portions to the base portion. The pair of deformable leg portions change shape from an initial shape to an extended shape in response to an external applied force and recover to a retracted shape upon removal of the force. The lancet cartridge also has a lancet having a tip end, an opposing base end, and an axis extending between the tip end and the base end. A portion of the lancet is disposed between the pair of deformable leg portions of the U-shaped support. The lancet is movable between a starting position, an extended puncturing position, and an ending position along the axis of the lancet in a path defined by the U-shaped support. When the lancet is in the starting position, the tip end of the lancet is disposed at least partially through the base portion of the U-shaped support, and the U-shaped support is in the initial shape. When the lancet is in the extended puncturing position, the tip end of the lancet is extended through the base of the U-shaped support, and the U-shaped support is in the extended shape. When the U-shaped support recovers to its retracted shape upon removal of the force, the lancet is retracted to the end position.

摘要： Determination of an analyte such as glucose in a sample is done making use of a plurality of electron transfer reagents, for example two electron transfer reagents, that work together to transfer electrons between the enzyme and the electrodes. The first electron transfer agent is a mediator that interacts with the enzyme after it has acted on the analyte to regenerate enzyme in its active form. The second electron transfer agent is a shuttle that interacts with the electrodes and optionally the mediator. The oxidation and reduction of the shuttle serves as the major source of current that is measured as an indication of analyte.

摘要： Electrochemical test cells are made with precision and accuracy by adhering an electrically resistive sheet having a bound opening to a first electrically conductive sheet. A notching opening is then punched through the electrically resistive sheet and the first electrically conductive sheet. The notching opening intersects the first bound opening in the electrically resistive sheet, and transforms the first bound opening into a notch in the electrically resistive sheet. A second electrically conductive sheet is punched to have a notching opening corresponding to that of first electrically conductive sheet, and this is adhered to the other side of the electrically resistive sheet such that the notching openings are aligned. This structure is cleaved from surrounding material to form an electrochemical cell that has a sample space for receiving a sample defined by the first and second conductive sheets and the notch in the electrically resistive sheet.
