Cannula`s coupling, has socket and/or plug comprising opening, so that opening connects channel for providing fluid in environment in one resting position, and isolating fluid from environment in another resting position

摘要

The coupling has a plug (12) lockable into a socket (14) in two resting positions. The socket and/or the plug comprise an opening (28), so that the opening connects a channel (16) for providing fluid e.g. blood, in the environment in one resting position, and isolating the fluid from the environment in another resting position. The channel is arranged in such a manner that the fluid flows through the coupling in a locked condition.
