Abstract
Abstract A retainer of pliable construction having a conical portion for insertion into a fistula or other body opening to provide a seal to prevent outward passage of fluids. An end segment of the retainer is cylindrical and has an annular edge which grips the tube outer wall surface to prevent tube slippage. An open internal area of the retainer permits lateral tube displacement. A modified retainer receives multiple tubes. The retainer is held in place by an adhesive equipped strip rotatably positionable for securement to the body. The strip may be apertured at its ends for reception of a belt.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
126 words
A retainer for flexible tube entering an opening in the human body and comprising in combination, a base for disposition adjacent an opening in the body, flexible attachment means on said base and adapted for attachment to the exterior of the body, a conical projection on said base of a highly resilient nature including an end segment, said conical projection for partial insertion into the body opening so as to surfacially engage body tissue defining said opening to provide a seal therewith, said end segment having an annular edge for frictional engagement with the tube outer wall to retain same against axial displacement, said base and said conical projection defining a circular groove, said flexible attachment means having an inner edge rotatably confined in said groove.
