FIELD: medicine.
SUBSTANCE: venous blood filtration apparatus comprises a glass graduated cylinder 1 with an inlet 12 for venous blood supply and an outlet 13 for venous blood outflow, enclosed in a transparent plastic casing 2 with two tubes 3 and 4. The lower tube 4 is designed to deliver water heated to +36°C to the casing 2, while the upper tube 3 is used for air outlet from the casing 2. At the bottom of the glass graduated cylinder 1, there is a plastic grating 5 whereon a calibrated filter 7 of pore diametre equal to 5 mcm is fixed with a metal ring 6. The cylinder 1 accommodates an in-built piston 8 with a rod 9, and the piston has two channels 10 of different diametres on a junction of which there is a metal ball 11 for air discharge from the cylinder 1.
EFFECT: accelerated venous blood examination result with maintained precision of blood cancer cell detection, simplified designed of the related apparatus.
