A chemical analyzer includes a slide transport mechanism having a slide track adapted to hold a plurality of reagent test slides, a sample metering device, an incubator formed as a part of the slide transport mechanism to precisely maintain the temperature of the reagent test slides, a slide ejector mechanism to remove the slides from the slide transport mechanism, a sample preparation station, which includes a centrifuge, and associated electronics and software. The slide transport mechanism holds a plurality of trapezoidally-shaped reagent test slides about its circumference, which slides are loaded onto the transport mechanism by the slide inserter mechanism. The slide transport mechanism positions the reagent test slides under the sample metering device, which device deposits a predetermined volume of sample onto each slide. The slide transport mechanism also carries the slides above a reflectometer. After testing has been completed, the slide ejector mechanism automatically removes the reagent test slides from the slide transport mechanism.

A device for obtaining a sample from inside a body includes a tubular body portion defining a chamber for receiving a sample of material therein; a plunger assembly operatively associated with the tubular body portion, the plunger assembly having a stopper slidably disposed within the chamber of the body portion; feedback elements provided on the tubular body and/or the plunger assembly for providing a user with audible and/or tactile indications regarding an amount of displacement of the plunger assembly relative to the body portion; and a cutting element is provided to facilitate sample removal.

Tissue sampling device and method

A retaining clip for retaining reagent test slides in a stacked arrangement includes a first assembly having a first cover plate and at least two parallel, co-planar rails extending transversely from an inner surface of the first cover plate. A second assembly includes a second cover plate, and a rail receiving platform extending transversely from an inner surface of the second cover plate. The first cover plate and the second cover plate define between them a space for receiving the plurality of reagent test slides. The rails of the first assembly include ratchet teeth, and the rail receiving platform of the second assembly includes pawls. The pawls engage the ratchet teeth to prevent the separation of the first assembly and the second assembly and to securely but removably hold the plurality of reagent test slides in a stacked arrangement between the first and second cover plates.

Retaining clip for reagent test slides

Invention performs an assay to determine presence or quantity of specific analyte in fluid sample. Representative device has two separate flow paths established sequentially in device with a single user activation step. First flow path delivers sample, and conjugate soluble binding reagents to solid phase. If analyte is present, an analyte:conjugate complex is formed and immobilized. Sample volume delivered by first path determined by absorbent capacity of solid phase, and not by amount of sample added to device. User need not measure sample volume. Sample/conjugate mixture is prevented from entering second flow path because capillary and surface energy of second flow path prevent it from being wetted by this mixture. Second flow path allows wash reagent to remove unbound conjugate and sample from solid phase to the absorbant, and optionally deliver detection reagents. Adaptable for many formats including, sandwich immunoassays, colloidal gold, sol particle, heterogeneous generic capture, and competitive assays.
