HYDRAULIC PUMP WITH DISPOSABLE COMPONENT Russian patent published in 2012 - IPC A61M5/142 

FIELD: medicine.

SUBSTANCE: group of inventions refers to medicine. A hydraulic pump comprises a drive unit having a body, a drive membrane, and at least one drive designed for moving the drive membrane between at least first and second positions. A driven device comprises a body, a liquid canal extending between an inlet to an outlet, and also at least one driven membrane limiting at least a portion of said liquid canal. The driven device is designed for random coupling with said driving device so that said driven membrane is coupled with said driving membrane to provide thereby movement of said driven membrane when moving said driving membrane causing thereby liquid injection through said driven device between the inlet to the outlet. A vacuum pumping means is designed for vacuum pumping of the coupling of the driven membrane and the driving membrane. What is disclosed is the method for liquid injection with using a hydraulic pump.

EFFECT: enabled accessible sterilisation.
