Pathology Specimen Preparation

In this arrangement of the conventional slide preparation method, pathology specimens are prepared on nonbreakable clear plastic chips and mounted in pathology aperture cards to facilitate compact storage and retrieval by data processing techniques.

Assume a gross tissue specimen is treated with formaldehyde, coated with paraffin, then microtomed, i.e., sliced in strata-like wafers into separate specimens, and placed in a water bath in conventional manner. A clear, flexible, plastic film chip 1 is removed from stack 2 on work table 3 and placed under spring clamp 4 on stiff plastic chip holder 5, the size of a conventional glass slide. An identifying number is applied to all chips 1 for a particular patient by hot- stamping or the like. The technician then scoops from the water bath onto chip 1 a microtomed specimen 6 and places 5 and 6 in an oven to melt the paraffin and evaporate the water, as in the conventional method. Chip 1, while retained on holder 5, is stained and rinsed, then placed at 8. It is then temporarily released from the holder, cleaned with solvent from well 9, and covered with mounting medium from well 10. A cover slip 11, is removed from stack 12, applied over specimen 6, and smoothed by a glass rod 13 kept in recess 14 to provide a chip- specimen-slip sandwich 15 that is temporarily placed in holder 5. then delivered to the physician for microscopic examination and diagnosis.

After sandwich 15 is returned to th...
