Abstract

1. Ventilation device (15) for a medical liquid system comprising an air-permeable hydrophobic layer (21) closing the liquid system, and a layer (21) of hydrophilic material provided at the hydrophobic layer (21) side confronted with the liquid and becoming substantially air-impermeable when wetted with the liquid, characterized in that the hydrophilic layer (20) and the hydrophobic layer (21) are closing in a direct mutual surface contact an opening of the liquid system.
