SYSTEM FOR FLUID DELIVERY AND ITS APPLICATION Russian patent published in 2017 - IPC A61M5/19 

FIELD: medicine.

SUBSTANCE: device comprises the first and the second syringe, similarly oriented for forming feed direction, and a connecting member attached to the first syringe piston and mechanically coupled to it. Syringe pistons are configured to slide within the respective syringe cylinder, the second syringe piston is adjustable in length. Mechanical coupling or uncoupling of the connecting member with the adjustable length piston of the second syringe is effected by piston lengthening or shortening. The ratio between greater and lesser lengths of the second syringe piston is at least 1.2. Connecting element movement in the feed direction ensures synchronized movement of each of the mechanically interlocked pistons longitudinally sliding inside the corresponding cylinders of the first and the second syringe.

EFFECT: possibility for one unit to supply different fluids while varying their ratio.
