DEVICE FOR CONTROL OF LOW FLOW RATES Russian patent published in 2023 - IPC A61M5/175 G05D7/06 

FIELD: medicine.

SUBSTANCE: devices for regulating low rates of flows moving in elastic capillary tubes. A drive rod is installed in the housing with the possibility of reciprocating movement and interaction with an elastic tube installed in a removable U-shaped element in the form of a bracket connected from the outside to the housing, in which a hole is made for the drive rod to pass when the flow area of the elastic tube changes. The drive and actuator parts of the device are mounted in the housing, interconnected by a gear train of two gears designed to receive a mechanical impulse from the drive gear of the drive part to the driven gear of the executive part and open or close the section of the elastic tube during the reciprocating movement of the rod forming screw-nut transmission with driven gear.

EFFECT: device for regulating low flow rates moving in elastic capillary tubes, simple in design, compact, reliable and easy to use, the principle of operation of which is based on mechanical clamping of the tube flow area by a drive regulator for use in medicine and in a wide range of devices both laboratory and process.
