Abstract
Abstract A catheter structure for insertion in an opening of a body having a support member frictionally slidable along the catheter to a desired position; the support member which enters the body has an annular extension engaged by an adhesive patch which extends beyond the annular extension and may engage the skin of the body to position the catheter; a closure member may be provided for the outer end of the catheter to prevent loss of contents of inserted material until the closure is removed.

Claim 1
Independent Claim
203 words
A catheter assembly comprising the combination of a catheter tube and a supporting member on said tube having a hollow nipplelike configuration comprising a bulbous tip with an opening flexibly and frictionally gripping said catheter tube; said supporting member terminating in a radial flange having one face to engage the skin of a patient marginally about a body opening; an adhesive patch having an aperture and said catheter tube passing therethrough with said aperture in generally axial alignment with the opening in said bulbous tip so that said catheter tube may pass through said patch aperture and through said bulbous tip opening into a body opening; said adhesive patch marginally encompassing the opposite face of said flange and extending radially outward thereof for an area greater than the area of said flange and have adhesive thereon to adhere to the skin of a patient and to said opposite face of said flange to thereby secure said supporting member for support of said catheter tube within a body opening; wherein said catheter tube is adjustable to frictionally held positions in said supporting member and thereby in a body opening; and whereby said bulbous tip aids securement of said supporting member in a body opening.
Claim 2
Dependent Claim
