COMBINED LANCET AND ELECTROCHEMICAL ANALYTE-TESTING APPARATUS

摘要

A sensor assembly for electrochemical detection of an analyte when associated with a meter unit, with a collar member (34), a skin-contact ring (3) and an electrochemical sensor (32), wherein the skin-contact ring comprises a wall member having a central opening with first and second open ends formed therethrough the electrochemical sensor is disposed adjacent to the skin-contact ring and extends across the first open end of the skin-contact ring, said sensor comprising reagents for generation of an electrochemical signal in response to the presence of analyte and an adsorptive member for absorbing fluid placed within the central opening of the ring and transporting the fluid into reactive proximity to the reagents, and an electrical contact for transmitting the electrochemical signal from the sensor; and the collar member comprises a wall member having a central opening for receiving a portion of the meter unit and holding it in position with respect to the sensor and the skin-contacting portion.
