Abstract

An apparatus for storing and dispensing a continuous band of medical reagent test strips is disclosed which includes chambers for the storage of used and unused portions of the continuous strip separated by barrier member to prevent cross-contamination there between. A substantially flat interim space is provided between the accesses to the chambers wherein tests may be run utilizing the samples in conjunction with the strips. Mechanical means is provided for advancing the band of medical test strips as necessary. The apparatus may be fabricated of suitable, moldable plastic material which may be discarded after the band of unused medical reagent test strips is exhausted.

Claims

1. A self-contained, disposable cartridge unit for storing and dispensing a continuous band of chemical reagent test strips for use with the chemical analyzing apparatus, said cartridge unit comprising:

a first chamber for containing the unused portion of said band of test strips in substantially coil form;

a second chamber for containing the used portion of said band of test strips in substantially coil form;

barrier means in said cartridge unit internally isolating said second chamber from said first chamber;

oppositely facing spaced slotted openings in said first and said second chambers to permit the passage of said band of test strips from said first to said second chamber;

integral fixed platen for continuously supporting said band of said test strips between said first and second chambers wherein the addition of specimens to said test strips and the testing thereof may take place;

a single, drivable take-up reel associated with said second chamber having a sprocket adapted to be externally driven; and

alignment slots for positioning said disposable cartridge unit in said chemical analyzing unit.

2. The apparatus of claim 1 wherein an extension of said platen provides a substantially smooth curve exit channel for said first chamber for the protection of exiting unused strips.

3. The apparatus of claim 1 further comprising closure means associated with said slotted openings to prevent contamination of said test strips when not in use.

4. The apparatus of claim 1 including means for positioning said strips in said band in said intervening space.

5. The apparatus of claim 4 including a desiccant ascociated with the volume of said first chamber to preserve said unused strips.
