Abstract:
A delivery apparatus for pressurized medical liquids has a reservoir for medical liquid and a pressurizing means configured for pressurizing medical liquid to a driving pressure; with a diffusion barrier arranged to float on medical liquid in the reservoir and disposed to cover substantially the entire surface of the medical liquid in the reservoir for the purpose of preventing diffusion of gas present in the reservoir into the medical liquid.
