DEVICE FOR IRRADIATION OF BIOLOGICAL LIQUID Russian patent published in 1994 - IPC

FIELD: medical engineering. SUBSTANCE: device comprises means for intake and return of liquid, irradiation unit, reversible pump, liquid receiver with main channel and pressure-equalizing channel which communicates with the atmosphere through conditioning unit incorporating air-processing device. The latter has the form of either a filter with porous element or an ultraviolet radiation source with reflector. Conditioning unit may have selector valve whose control circuit is connected to intake/return mode switchover unit which directs air flow through air-processing device only when air enters into container. EFFECT: higher sterility of liquid collection in the course of irradiation. 8 cl, 5 dwg
