摘要:
A strip ejection system for holding and ejecting a strip is provided. The system includes a body and a strip movement section. The strip moving section includes all elements of the system that are involved with moving the strip, including a pressing element for pressing against the strip to move the strip from a first position to a second position. The pressing element is the only element of the strip movement section that is movable relative to the body.

There is disclosed a method of measuring formation of a barrier to restrict or reduce movement of an electroactive species. The method comprises providing an electrochemical cell (1, 2, 3) having a working electrode (23, 24) and a counter electrode (23, 24) spaced from the working electrode, providing a subject component, a testing component and at least one electroactive species within the cell, the subject and testing components being intended to cause the formation of a barrier to restrict or reduce movement of an electroactive species, applying a potential between the working electrode and the counter electrode sufficient to produce a current proportional to the concentration of the electroactive species being measured, and measuring the current at the working electrode to obtain a measure of the formation of the barrier to restrict or reduce movement of the electroactive species. The electrochemical cell may be in the form of a multi-cell strip (10) with cells (1, 2, 3) formed in cut-outs in an insulating spacer layer (20) interposed between upper and lower layers (21, 22).

摘要:
This invention relates to a biosensor and more particularly to an electrochemical biosensor for determining the concentration of an analyte in a carrier. The invention is particularly useful for determining the concentration of glucose in blood and is described herein with reference to that use but it should be understood that the invention is applicable to other analytic determinations.
摘要:
The invention disclosed in this application is a method and device for combining the sampling and analyzing of sub-dermal fluid samples, e.g., interstitial fluid or whole blood, in a device suitable for hospital bedside and home use. It is applicable to any analyte that exists in a usefully representative concentration in the fluid, and is especially suited to the monitoring of glucose.
摘要:
This invention describes a quantitative, inexpensive, disposable immunosensor that requires no wash steps and thus generates no liquid waste. Moreover, in preferred embodiments of the sensor no timing steps are required of the user, and the sensor can be readily adapted to antigen-antibody interactions over a wide kinetic range.
摘要:
Electrochemical sensors for investigating a physiological sample and methods of manufacture are disclosed. The sensor includes an electrochemical reaction cell, having electrodes and a reagent, and laterally spaced electrical contact points for electrically communication with a meter. Further described herein is a multi-chambered sensor having an electrochemical reaction cell and an immunological cell. The multi-chambered cell can also include a pre-chamber.
