ABSTRACT:
A delivery apparatus for pressurized medical liquids has a primary reservoir and a primary pressurizing arrangement configured for removably pressurizing medical liquid in the primary reservoir to a delivery pressure. A secondary reservoir has an inlet connected via a valve to receive pressurized liquid from the primary reservoir. As secondary pressurizing arrangement is arranged for supplying a compensating pressure to the received pressurized liquid to maintain it at substantially the delivery pressure as pressure is reduced in the primary reservoir, particularly during refilling with medical liquid from an unpressurized source.
