A nasal cannula includes a distribution conduit running along a virtual distribution path. The distribution path defines a longitudinal direction and has two branch openings. A respective supply conduit branches off from each branch opening. The distribution conduit also has two coupling openings arranged spaced apart from the branch openings. The nasal cannula has a plug via which one of the two coupling openings can be sealed as a closure opening. Another of the two coupling openings is designed as a supply opening. The plug has a flow-directing configuration with an exposed flow-directing surface. In a reference state in which the plug is closing the closure opening, the flow-directing surface is arranged in the distribution conduit in the longitudinal extension region of at least one branch opening and positioned relative to the distribution path to deflect treatment gas flowing in the distribution conduit from the supply opening along the distribution path towards at least one of the branch openings.

A magnetic isolating apparatus () for isolating magnetic particles () from a suspension has an immersion section () which is designed to be temporarily immersed in the suspension, a guide apparatus () which extends along a guide path (F), a magnet arrangement () which is guided by the guide apparatus () such that it can be moved between an active position which is situated close to the immersion section () and an inactive position which is positioned further away from the immersion section () along the guide path (F), so that a magnetic field in the region of the immersion section () can be changed by moving the magnet arrangement () between the active position and the inactive position, and a drive apparatus () by which the magnet arrangement () can be driven to move at least in a direction between the active position and the inactive position, wherein the drive apparatus () is coupled in a non-physical manner to the magnet arrangement () by a force field and/or a fluid so as to transmit drive force.
