DOSING FLUID MEDIUM IN AMOUNT OF LESS THAN ONE MILLILITER Russian patent published in 2019 - IPC F04B43/09 B65B3/04 

FIELD: physics.

SUBSTANCE: invention relates to a filling device operating with a peristaltic metering device, as well as a method for filling such a device. Device comprises flexible tube (13), element (12) with back pressure, multiple actuators (11), as well as drive (17). Flexible tube (13) is straightly laid along element with back pressure (12), thus forming longitudinal axis. Actuating elements (11) are arranged parallel to each other along longitudinal axis. They can be driven by drive (17) relative to flexible tube (13). Flexible tube (13) can be compressed between actuators (11) and element (12) with back pressure by moving actuators (11). Each of actuating elements (11) is independently and linearly movable by drive (17) along actuating axis, which is perpendicular to longitudinal axis of flexible tube (13) from initial position, in which flexible tube (13) is subjected to compression in least degree and in final position, in which flexible tube (13) is compressed and plugged between corresponding actuating element and counter pressure element (12).

EFFECT: peristaltic dosing device enables accurate and multiple delivery of doses in relatively small volumes in a sterile medium.
