Abstract
A coupling system for a closed fluid transfer system includes at least one coupling member and at least one counter coupling member. The coupling member includes a coupling member sealing member that has at least one reversibly openable and closable coupling member sealing member opening facing a coupling side of the coupling member. At least one activation member engages the coupling member sealing member. The counter coupling member includes a counter coupling member sealing member that includes a reversibly openable and closable counter coupling member sealing member opening facing a coupling side of the counter coupling member, and is configured to move the activation member to a position with minimum distance to a fluid connection of the coupling member upon coupling of the coupling member and the counter coupling member. The counter coupling member sealing member opening is opened in a connected state by the coupling member sealing member.
