摘要：
A crush and kink resilient tubing system for an infusion system. The tubing system has an inner sheath with an inner wall forming a passageway for an infusion fluid, and an outer sheath surrounding the inner sheath, wherein the inner sheath material which has a structural rigidity greater than a structural rigidity of the material of the outer sheath, such that a neutral strain line is formed closer to the tube's inner wall than to its outer wall. This combination of materials characteristics and relative thicknesses provides autonomous recovery and rebounding of the tube following removal of a shape deforming force.
