A sensor utilizing a non-leachable or diffusible redox mediator is described. The sensor includes a sample chamber to hold a sample in electrolytic contact with a working electrode, and in at least some instances, the sensor also contains a non-leachable or a diffusible second electron transfer agent. The sensor and/or the methods used produce a sensor signal in response to the analyte that can be distinguished from a background signal caused by the mediator. The invention can be used to determine the concentration of a biomolecule, such as glucose or lactate, in a biological fluid, such as blood or serum, using techniques such as coulometry, amperometry, and potentiometry. An enzyme capable of catalyzing the electrooxidation or electroreduction of the biomolecule is typically provided as a second electron transfer agent.

An improved medication infusion set is provided of the type having a soft cannula for subcutaneous delivery of a selected medication to a patient. The infusion set comprises a cannula housing having a soft cannula protruding therefrom and a self-sealing septum mounted at an upstream end of the cannula. The cannula housing is initially assembled with an insertion hub having an elongated insertion needle extending through the septum and cannula for transcutaneously placing the cannula followed by separation of the insertion hub from the cannula housing. An infusion hub is then assembled with the cannula housing and includes a short infusion needle for coupling the cannula with the selected medication supplied from a source via a length of infusion tubing. The infusion hub includes a protective shroud plate protruding beyond a tip end of the infusion needle to minimize risk of patient contact therewith, and adapted for slide-fit reception into a matingly shaped slot formed in the cannula housing to insure a one-way and high strength interconnection between the cannula housing and infusion hub. Releasible latch members interlock the infusion hub with the cannula housing in a manner permitting periodic separation when desired.

An analyte monitor includes a sensor, a sensor control unit, and a display unit. The sensor has, for example, a substrate, a recessed channel formed in the substrate, and conductive material disposed in the recessed channel to form a working electrode. The sensor control unit typically has a housing adapted for placement on skin and is adapted to receive a portion of an electrochemical sensor. The sensor control unit also includes two or more conductive contacts disposed on the housing and configured for coupling to two or more contact pads on the sensor. A transmitter is disposed in the housing and coupled to the plurality of conductive contacts for transmitting data obtained using the sensor. The display unit has a receiver for receiving data transmitted by the transmitter of the sensor control unit and a display coupled to the receiver for displaying an indication of a level of an analyte. The analyte monitor may also be part of a drug delivery system to alter the level of the analyte based on the data obtained using the sensor.

A small volume sensor, and methods of making, for determining the concentration of an analyte, such as glucose or lactate, in a biological fluid, such as blood or serum, using techniques such as coulometry, amperometry, and potentiometry. The sensor includes a working electrode and a counter electrode, and can include an insertion monitoring trace to determine correct positioning of the sensor in a connector. In one embodiment, the sensor determines the concentration of the analyte by discharging an amount of charge into the sample, determining the time needed to discharge the charge, and determining the current used to electrolyze a portion of the analyte using the amount of charge and the amount of time.
