HYDRODYNAMIC FOCUSING DEVICE Russian patent published in 2024 - IPC F15B15/00 G01N15/10 G01N15/14 

FIELD: machine building.

SUBSTANCE: hydrodynamic focusing device, preferably made in the form of a microfluidic device, comprises first flow channel (4), second flow channel (8) of reduced size, coverage area (12) connected with arrangement on one axis between the first flow channel (4) and the second flow channel (8), and tube (14) containing housing (16) and channel (18) for inlet of analysed fluid medium and passing from preferably inclined wall (20), limiting coverage zone (12), inside said zone. Housing (16) and channel (18) for inlet of analysed fluid are both made with elongated, preferably drop-shaped profile, having front edge (28) facing the first flow channel (4), and opposite to each other long edges (30a, 30b), mutually narrowing towards rear edge (32).

EFFECT: broader functional capabilities.
