Disclosed herein are electrochemical sensor dispensing methods and apparatus. The sensors dispensers can include an elongate body having a proximal end and a distal, the elongate body including a proximally positioned dispensing surface with an opening for dispensing a sensor. A storage chamber having a series of connected sensors is positioned distally and can feed a proximally positioned sensor feeder mechanism. The feeder mechanism includes an elongate member having a first end and second end, the second end adapted to pivot between a sensor engaging position and a sensor feeding position.

Sensor dispenser device and method of use

Described and illustrated herein are exemplary methods of operating an analyte measurement system having a meter and a test strip. Such methods may be exemplarily achieved by determining a first glucose concentration by measuring a first reflectance at about a first wavelength at a testing surface of the pad; measuring a second reflectance at about a second wavelength; formulating at least one equation to correct the first glucose concentration for temperature or hematocrit effects using the second reflectance at about the second wavelength; determining a second glucose concentration using the first glucose concentration, the second reflectance at about a second wavelength; and displaying the second glucose concentration that is corrected for temperature and hematocrit effects.

Methods and systems to correct for hematocrit effects

Electrochemical sensors for investigating a physiological sample and methods of manufacture are disclosed. The sensor includes a longitudinally extending reaction cell, having electrodes and a reagent, and laterally spaced electrical contact points for electrically communication with a meter. An array of such sensors is further disclosed including connective flaps for joining adjacent sensors. In use, the array of sensors can be stored in a folded configuration and dispensed individually.

Method and apparatus for electrochemical analysis

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.

Methods of auto-calibrating a meter are disclosed. In one aspect, the method can include determining a set of calibration information applicable to a sensor and storing the calibration information onto a tag element associated with a sensor dispenser. The tag element can be placed into communication with a reader element that is associated with a meter and which is configured to receive the calibration information so as to allow the meter to use the calibration information in a calibration procedure. Various aspects of a system for auto-calibrating a meter are also disclosed.

A medical device package includes a body with at least one chamber therein, a proximal end and a distal end. The medical device package also includes at least one deformable projection within the chamber(s). Furthermore, the deformable projection is configured to deform resiliently upon contact with a medical device during insertion of the medical device into the chamber and, thereby, removably retain the medical device within the chamber.

Devices and methods for analyte concentration determination are provided. The subject devices have a housing having an aperture, a lancing element having a lancet held therein disposed within the housing, a manner for activating the lancing element to displace the lancet to provide an incision in an area of skin to provide physiological sample, and a manner for determining whether a sufficient amount of the physiological sample is present at the surface of the skin. The subject methods include lancing an area of skin to provide physiological sample at the surface of the area of skin, illuminating the physiological sample present at the surface of skin, detecting light reflected from the physiological sample, and determining whether the physiological sample is present in an amount sufficient for analyte concentration determination based upon the detected light. The subject invention also includes kits for use in practicing the subject methods.

A lancing device with automatic stick and lance return features is disclosed. A drive mechanism within the unit comprises a slider-crank linkage combination. It is biased by a spring member to cause automatic firing once a crank member advanced by a user causes movement of an internal linkage member beyond its fully-cocked position. After firing, the lance is withdrawn so as not to pose a threat of secondary injury to the user. In use, the device is substantially silent though its course of operation. Yet, its configuration lends itself to producing a very quick, virtually painless stick with minimal recoil or shock to the device.

The invention provides a substantially moisture-proof, air-tight apparatus for both dispensing a plurality of diagnostic test strips and testing a biological fluid dispensed onto the strip. One strip may be advanced for use in testing using a single, translational movement.

Test device with means for storing and dispensing diagnostic strips

Apparatuses and methods for determining the concentration of an analyte in a physiological sample are provided. The subject apparatuses include at least one light source, a detector array, means for determining whether a sufficient amount of sample is present on each of the plurality of different areas, and means for determining the concentration of the analyte based on the reflected light detected from those areas determined to have sufficient sample, where areas having insufficient sample are not used in analyte concentration determination. The subject methods include illuminating each area of a test strip, obtaining reflectance from each of the different areas, determining which areas have sufficient sample based on detected light therefrom and deriving analyte concentration from the areas determined to have sufficient sample, where areas determined not to have sufficient sample are not used in the derivation. Also provided are kits for use in practicing the subject methods.

A support for articles having an elongated portion has a single shaft and a head made of wire. The head is attached to one end of the shaft. The head consists of a single wire formed into loops. The loops are formed at an angle with the shaft. The form of the support can resemble a flower, with the shaft representing the flower stem, the head representing the flower head and the loops representing the shape and arrangement of the flower petals. The support can be made from a single piece of wire. The invention can be used to support plant stems, arrange cut flowers in a bouquet or store writing implements.

Support for articles having an elongated portion

A hollow, frustum-shaped disposable device is used in an apparatus for measuring the concentration of an analyte in a sample of a biological fluid. The smaller end of the frustum has a porous membrane, to which a sample of the fluid may be applied. Preferably, a reagent in the membrane reacts with the analyte to cause a color change. The device is mounted on a meter, which measures the color change and computes from the change the analyte concentration in the sample. The apparatus permits remote dosing of the device, which minimizes the likelihood of cross-contamination between the user and the meter. Devices can be mounted on the meter and released from the meter without touching them, to further protect against contamination.
