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.Un système de soupape sans aiguille comprend une canule comprenant une pointe de canule ; une soupape comprenant une pointe de soupape dans laquelle la soupape est disposée autour de la canule; et un boîtier comprenant un boîtier de pointe, dans lequel la pointe de la canule, la pointe de soupape et la pointe du boîtier comprennent une surface plate lorsque le système de soupape sans aiguille est dans une position étanche.
