METHOD AND APPARATUS FOR FILTERING PARTICULATE MATTER FROM FLUIDS OF BIOMEDICAL INTEREST AND EXAMINING SAME

摘要

A flexible, disposable pouch with internal filters (9), compartments (7, 13) and reagents (18), and having a transparent wall (1, 2) is used to filter, treat, and microscopically examine the filtrate or residue without reopening the pouch. The specimen fluid is moved from one compartment (7) to another (13), or through the filters (9), and the reagents (18) are released as a result of the pressure exerted as the pouch is rolled.
