AUTOMATIC SWITCHABLE PUMP SYSTEM Russian patent published in 2013 - IPC A61M5/168 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medical equipment. An automatic switchable pump system comprises controllers connected with drivers for sequential fluid supply from a number of drug containers into a connector with a counterflow barrier to introduce the fluid into the patient. Internal fluid pressure in the connector is determined by a pressure sensor, or signal generators for the controllers. The controllers on the basis of at least sensor signals make the drivers working downstream and upstream so that decreasing and increasing fluid pressure in the connector during switching between an empty syringe and a filled syringe thereby eliminating formation of an excessive dose and completion of the injection therapy.

EFFECT: independent syringe pumps are connected in a switching network to form a module system.
