FIELD: medical engineering.
SUBSTANCE: device has reservoir for keeping dosing liquid. The reservoir is connected by tube for supplying liquid to manually driven liquid-supplying pump for moving liquid from storage reservoir to outlet catheter via pipe for discharging measured dose. The pipe for discharging liquid has a unit for initiating movement of liquid. The pump has casing having pressurizing and dosing chamber separated with rigid partition perforated in the peripheral zone and having flexible membrane disposed in central zone on the same side with pumping chamber to close the perforated holes.
EFFECT: simplified design; high reliability of operation.
