Abstract
A disk for holding, centrifuging and microscopically viewing fluid samples is provided. The disk includes a plurality of reaction wells radiating outwardly and includes a barrier to restrain particles during centrifugation. This disk is used in the disclosed apparatus and method for blood typing and related procedures. The apparatus comprises sample loading, mixing, centrifuging, incubating, viewing and sterilizing stations. Additionally, a photomicrograph of the sample is taken, digitized, displayed, stored and printed along with corresponding test results and interpretation.
Claims6
A specimen disk for receiving a plurality of fluid specimens to be subjected to centrifugal separation and visual analyses comprising:
- a generally circular disk member having a plurality of reaction wells radiating outwardly from a central bore;
- means for accurately positioning said specimen disk during said centrifugal separation and visual analysis;
- means for introducing fluids into each of said reaction wells;
- a plurality of waste chambers each associated with a corresponding one of said plurality of reaction wells;
- and
- barrier means for trapping particulates when said disk is subjected to said centrifugal separation, said barrier means being positioned between each reaction chamber and a corresponding waste chamber and including an upstanding wall with inner and outer surfaces, an upper portion of said inner surface being substantially curved upward and inward toward said central bore in a generally C-shaped form in cross-section wherein
- each of said plurality of reaction wells includes a viewing area for containing a portion of said fluid specimen after said centrifugal separation and facilitating microscopic viewing of said fluid specimen therein.
