Abstract (en)
[origin: WO2005110337A1] The invention relates to an enteral feeding tube comprising a jejunal tube (2) which is arranged in jejunum and comprises a proximal end, a distal end (3, 4), and a lumen (5) between said two ends. Said tube (2) comprises an at least double-layer structure with an outer first layer (2a) and a second layer (2b) adjacent to the outer layer, the first layer (2a) consisting of a material which is harder than the material of the second layer (2b). Preferably, the tube has a triple-layer structure with an outer layer (2a), an inner layer (2b), and an internal layer (2c), the internal layer (2b) being softer than the outer and inner layers (2a, 2c). The multiple-layer structure of the tube consisting of materials of different hardnesses improves the flexibility, advancing behaviour and buckling resistance of the feeding tube. The invention also relates to a tube system consisting of the feeding tube and a gastric tube.
