    an inner tube releasable with the outer tube and having a through-channel for air communication between the cavity of the middle ear and the outside air, wherein the inner tube includes a flange at one end that prevents an opposite end of the inner tube from inadvertently being pushed too far into the middle ear yet past the internal end of the outer tube.
