FIELD: medical engineering.
SUBSTANCE: device has sealed reservoirs, containing substances, and piston mechanism, having piston cylinder, piston and piston rod. Device for moving liquid between the reservoirs is mounted in piston cylinder lumen. The device has separating piston and compression unit arranged in series. The unit designed as casing or carcass is mounted in projection of its external cylindrical part along the perimeter. Hollow internal lumen of has exit to piston projection inward from its external perimeter. The separating piston makes two connections with the piston cylinder and compression unit at the same time. The separating piston is movable into compression unit lumen with compression or change in shape taking place at the same time. The compression unit allows to make communication between reservoirs.
EFFECT: simplified design.
