Appl. No.:

10/230659

Inventors:

Derek O'Hara - Tourlestrane, IE
Brendan Duggan - Strandhill, IE
Gail Comer - Libertyville IL, US

Liliana Sanmiguel - Powell OH, US

International Classification:

A61M031/00

US Classification:

604/538000, 604/500000

Abstract:

Feeding tube assembly includes a feeding tube made of a polyurethane, preferably Carbothane, and a feeding tube adaptor including at least an inlet conduit and an outlet conduit. In one aspect, the feeding tube adaptor is made of a substantially rigid material, and the exterior surface of the outlet conduit defines a retention member to engage an interior surface at a first end portion of the feeding tube when the outlet end of the outlet conduit is inserted within a lumen defined in the feeding tube. In accordance with another aspect, the tube adaptor is provided with a removable cap to close selectively the inlet conduit, and both the inlet conduit and the cap are made of polyurethane. The cap has an engagement surface to engage a corresponding surface of the first inlet conduit, wherein the engagement surface of the cap has a surface configuration different than that of the corresponding surface of the first inlet conduit. This difference in surface configurations can be established by providing one or both of the surfaces with a series of protuberances, a series of indentations, a different cross-sectional shape, or a combination thereof.

International Classification:

US Classification:

604539, 604284, 604256

Abstract:

A feeding tube assembly includes a feeding tube, a polyurethane feeding tube adaptor having an inlet conduit and an outlet conduit, and a removable cap for selectively closing the inlet conduit. The surface configuration of the cap that causes frictional engagement with the inlet conduit is noncomplementary therewith in a common transverse plane and has a cross-sectional shape substantially different than that of the corresponding surface configuration of the inlet conduit. This difference in surface configurations can be established by providing one or both of the surfaces with a series of protuberances, indentations, or other surface variations.
