A compressible cannula valve comprises a housing having a housing wall around a cavity and a housing opening. It further comprises a cannula having a base, a cannula tip extending within the cavity from the base toward the housing opening, and a lumen extending from the base to a radially oriented opening. A resiliently compressible valve surrounds the cannula and has a shoulder and a protrusion axially aligned with the radially oriented opening, the shoulder extends radially toward the housing wall and the protrusion extends radially into the radially oriented opening.
