LAYERED FLUID CIRCUIT FOR FLUID CARTRIDGE Russian patent published in 2023 - IPC B01L3/00 B29C53/06 G01N35/10 

FIELD: fluid cartridge device.

SUBSTANCE: group of inventions is related to a fluid cartridge device using a layered fluid circuit and to a method for assembling a fluid cartridge device. The device (100) contains: two or more layers (201, 202, 203) layer-by-layer connected to each other to form a planar substrate (122), one or more channels (124) formed within the substrate, and a flexible groove (126) , formed by a portion of the substrate containing a portion of at least one of the channels, which is partially separated or configured to be separated from the rest of the substrate. Moreover, the flexible groove includes the specified part of the substrate and the channel section contained therein and is configured to be deflected relative to the planar substrate from a non-deviated position, in which the flexible groove is essentially coplanar with the planar substrate, to a deflected position, in which part of the flexible groove is no longer aligned with the planar substrate. essentially a coplanar planar substrate.

EFFECT: creation of a device and method for a fluid cartridge, which provides the ability to selectively supply contained fluids to the observation area to perform one or more fluid operations on them and the ability to contain the fluid under a multilayer substrate.
