Abstract: A kink-resistant hose comprises a tubing and at least one anti-kinking member disposed within an interior volume of the tubing. The outer diameter of the anti-kinking member is less than the inner diameter of the tubing, wherein the anti-kinking member and the tubing are coextruded such that the anti-kinking member is free-floating within the interior volume of the tubing. A cross-sectional area of the anti-kinking member is less than the area of a circle with diameter equal to the maximal diameter of the anti-kinking member. The anti-kinking member thereby defines propped open flow channels, extending radially between an outer surface of the anti-kinking member and an inner surface of the tubing at a kink point, for conveying fluid through a kink in the tubing. A restraint mechanism located in at least the first distal end of the tubing restrains longitudinal movement of the anti-kinking member through the tubing.
