Abstract
Official abstract text for this publication.
A multi-layer odor barrier catheter tube for a fecal drainage catheter. 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.
First claim
Opening claim text (preview).
We claim: 1. A catheter tube for a fecal drainage system comprising: a first layer including a thermoplastic elastomer; a second layer including a thermoplastic elastomer; and a film layer intermediate the first layer and the second layer, the film layer including an odor barrier material, wherein the film layer is nylon 669. 2. The catheter tube of claim 1 , wherein the first layer defines an internal surface of the catheter tube and is the thickest lay…
