A fecal drainage system includes a collection bag and a catheter tube connectable to the collection bag. The catheter tube is a multi-layer odor barrier structure. The layers of the catheter tube include one or more thermoplastic elastomer layers and one or more odor barrier layers. For example, the catheter tube may comprise an inner thermoplastic elastomer (TPE) layer, an intermediate odor barrier film layer, and an outer TPE layer. Alternately, the multi-layer catheter tube includes an inner TPE layer sandwiched between outer layers of odor barrier film material.

The fecal drainage system of claim 1, wherein the collection bag has one or more walls having odor barrier properties. 8. The fecal drainage system of claim 1, further comprising a one or more additional layers of the catheter tube that are intermediate the first layer and the second layer in addition to the film layer. 9. A fecal drainage system comprising: a collection bag; anda catheter tube connectable to the collection bag, the catheter tube having a first layer including an odor barrier material, a second layer including an odor barrier material, and a third layer intermediate the first layer and the second layer, the third layer including a thermoplastic elastomer. 10. The fecal drainage system of claim 9, wherein the first layer of the catheter tube defines an internal surface of the catheter tube. 11. The fecal drainage system of claim 10, wherein the third layer of the catheter tube that is intermediate the first layer and the second layer is the thickest layer of the catheter tube. 12. The fecal drainage system of claim 9, wherein the first layer and the second layer of the catheter tube comprise nylon 669. 13. The fecal drainage system of claim 9, wherein the first layer and the second layer of the catheter tube comprise nylon 669 blended with a reactive rubber. 14. The fecal drainage system of claim 13, wherein the nylon 669 blended with a reactive rubber further comprises one or more lubricants. 15. The fecal drainage system of claim 9, wherein the collection bag has one or more walls having odor barrier properties. 16. A fecal drainage system comprising: a collection bag having one or more walls with odor barrier properties; anda catheter tube connectable to the collection bag, the catheter tube having a plurality of layers, at least one of the plurality of layers including an odor barrier material comprising nylon 669, and at least one of the other layers including a material selected from the group consisting of thermoplastic elastomer (TPE), ethylene methyl acrylate film (EMA), thermoplastic polyurethane (TPU), styrene-butadiene copolymer (SBC), thermoplastic vulcanisate (TPV), and ethylene propylene diene monomer (EPDM). 17. The fecal drainage system of claim 16, wherein the nylon 669 is blended with a reactive rubber. 18. The fecal drainage system of claim 17, wherein the nylon 669 blended with a reactive rubber further comprises one or more lubricants.
