Processing Basket and Probes Disposable Utility Lining System

Abstract

Improvements in a processing basket lining system for slide maker-stainer instrument. The utility liner is configured to sit on top of the processing baskets that are customarily occupied/filled with the processing reagents. The probe jackets are shaped to slip in and out without interfere with its capacity to dispense-drain reagents while submerged to the intended reagents in the processing baskets. The liners provide a surface between the processing baskets or probes and the reagents where debris can accumulate as a waste by-product of the process largely in quantities or simply just by the length of use time. The disposable utility lining system, processing basket and probe cover are disposable. The liners are preferably made of plastics. The material of choice is tested not to react with the processing reagent for a period of time, depending on the manufacturer's maintenance requirement.

Reference Numbers in the Figures

[0041] 10 processing basket. [0042] 20 basket utility liner. [0043] 21 lip. [0044] 29 alternative embodiment basket utility liner. [0045] 30 slide cassette. [0046] 31 slide. [0047] 32 robotic arm. [0048] 40 cover. [0049] 45 fill probe. [0050] 50 drain probe.

[0051] Medical instruments require daily maintenance of draining old and/or used reagents, and commonly replace the basket with a clean set, if available, and refill the basket with new reagents. Laboratory personnel will then clean the old set of baskets with methanol, dry the baskets and prepared for the next maintenance cycle. On occasion, when a second set of baskets are not available, the recently cleaned baskets will be placed back for use. The probes are dried and wiped clean with methanol to get rid of any residue that forms between cleaning cycles/periods that could interfere in the reading of the stained slides that could compromise the test results.

[0052] FIG. 1 shows the preferred embodiment of the basket utility liner 20 separated from the processing basket. The basket utility liner 20 is ideally a thin, molded liner that mimics the interior contour of a sink and sits inside the processing baskets 10. The molded liner is between 0.002 and 0.020 thick. The current basket utility liner 20 allows holding of filled reagents during processing. This processing basket utility liner 20 is configured to sit on a bar holder that is customarily occupied by numerous processing basket units.

[0068] The cleaning solution of methanol is the biggest hazard due to its classification which according to MSDS NO: 6000 Prepared by Alcohol QA, Technical Services, and Regulatory Affairs Department (909) 790-7500 Date Feb. 1, 2014 “Toxicological Data is flammable liquid and although practically non-toxic to animals, it is very toxic to humans.

[0069] The Notes to Physician during Emergency and First Aid procedure states that it is a very toxic substance, capable of producing blindness and death. The WHMIS Classification and Synergistic Materials is a flammable liquid, very toxic material and eye irritant. Unusual Fire and Explosion Hazards is associated with the vapors produced and may travel or be moved by air currents and ignited by pilot lights, other flames, sparks, heaters, electrical equipment, static discharges, and ignition sources at locations that are distal to the staining solution.

[0070] Thus, specific embodiments of a processing basket disposable utility lining system have been disclosed. It should be apparent, however, to those skilled in the art that many more modifications besides those described are possible without departing from the inventive concepts herein. The inventive subject matter, therefore, is not to be restricted except in the spirit of the appended claims.
