Method and apparatus for controlled instrumentation of particles with a filter device

摘要

A method and apparatus for the controlled instrumentation processing of cells and other particles with a filter device measures a parameter of the flow through the filter device of a fluid carrying the particles. A measure of the change of fluid flow through the filter device yields desired information for quantizing the particles and for quantizing the obstruction of the filter device by the particles. The method and apparatus typically operate automatically. Cytological test methods and instruments can employ the invention to quantize and to collect cells.
