Abstract
A method and apparatus for non-invasively withdrawing and accurately evaluating analytes quickly, painlessly and reliably from a biological subject automatically and controlling subsequent administration of therapeutic agents in response to such analyte sample analysis. Improvements are provided in electro-osmotic sample withdrawal, dosimetry and iontophoretic delivery subsystems, biosensors electrode construction and arrangement, intervenors, mediators, bolus delivery, and related subsystems.
Claims7
In a biosensor system the combination, comprising:
- an electrode at a high electrical potential, and
- means for physically and electrically isolating said electrode from the skin of a biological subject said means including a dropping resistor.
In a biosensor device, the combination comprising:
- a pair of electrodes;
- and
- a multi-layer membrane between said electrodes, said membrane being adapted to place one end of said membrane in contact with the skin of a biological subject.
In a sensor, the combination comprising:
- a pair of electrodes;
- means for applying a high D.C. voltage to said electrodes to generate a reducing agent;
- measurement means for measuring the electrical results of reaction to said reducing agent;
- and
- means for automatically reducing said high voltage to a low voltage for operation of said measurement means.
