DOSED LIQUID SUPPLY DEVICE Russian patent published in 2016 - IPC A61M5/142 

FIELD: medical equipment.

SUBSTANCE: invention relates to medical equipment, namely, to dosed liquid supply devices. Device comprises a dropper with a tube, outlet of which is below the dropper, and electromechanical tube clamp, configured for squeezing its cross section, installed between the dropper and tube end, equipped with an electric drive, to control its operation via a control circuit. Small stepping motor is used as a driver of the electromechanical tube clamp. Dropper is detachable and installed on the actuator of a weight sensor, made to rigidly fix its position on a support, weight sensor output is electrically connected to the control input of the control circuit of the motor. Electromechanical clamp and the motor are rigidly and detachably fixed on a support, the clamp includes upper and lower slots, articulated to rotate around horizontal axis, and is fixed on a support so that the longitudinal axis of its upper slot, rigidly fixed on a support is parallel to the drive shaft, provided with thread and bonded coaxially with the motor shaft, on the drive shaft there is a nut, upper edge of which is borne against the lower surfaces of the upper and lower slots, with the possibility of reciprocal movement along them.

EFFECT: using the invention provides liquid supply under gravity force and control of flow rate from zero to maximum, simple design and production.
