Spike with non-return valve function and filling device of a liquid system with spike

摘要

Disclosed is an anti-contamination device for preventing contamination of a fluid stored in a fluid container with a spike and a manually operable fluid blocking mechanism arranged directly downstream of the spike. A non-return valve is arranged between the spike and the fluid blocking mechanism, and that valve is adapted to allow only a flow from the spike in the direction of the manually operable fluid blocking mechanism.
