Title: Mixing adaptor system

Abstract: A mixing adaptor enables a material to be transferred from a first delivery means to a second delivery means and enables another material to be transferred from the second delivery means to the first delivery means. The adaptor has (i) a hollow main body having a first end, a second end, an interior surface and an exterior surface; and (ii) a septum positioned within the interior surface of the main body. A first channel is defined by a first portion of the interior surface of the main body and by a first side of the septum. The first channel has a primary opening at the first end of the main body and a secondary opening at the second end of the main body. A second channel is defined by a second portion of the interior surface of the main body and by a second side of the septum. The second channel has a primary opening at the second end of the main body and a secondary opening at the first end of the main body. First and second substantially flexible members extend from opposing sides of the septum for selectively closing the secondary openings of the first and second channels. In one embodiment, the septum is movable between a first position and a second position.
