Abstract: A reinforced hose (402) comprising an extruded core tube (404) having a circular cylindrical cross- section, a plurality of elongated reinforcement members (414), and a jacket layer (408). The plurality of elongated reinforcement members (414) are disposed within a wall of the core tube (404) and extend longitudinally between a first distal end of the core tube (404) and a second distal end of the core tube (404). The elongated reinforcement members (414) can extend in a substantially straight fashion or can extend in a helical fashion to thereby form a helix within the wall of the core tube (404). One or more of the plurality of elongated reinforcement members (414) has a greater rigidity than the wall of the core tube (404). A jacket layer (408) encapsulates the extruded core tube (404) and the plurality of elongated reinforcement members (414), and has a circular cylindrical cross-section that is larger than the circular cylindrical cross-section of the extruded core tube (404).

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.
