Abstract
Abstract A catheter support comprising an anchoring pad and a flexible strap, a portion of which is attached thereto, is disclosed. One side of the anchoring pad carries an adhesive compatible for use with human skin. One side of the strap carries a fastener material. With the pad in place, a catheter is laid against the pad, and the free end of the strap is folded across the catheter. The fastener material of the free end is pressed against the fastener material attached to the pad to hold the catheter in place. Alternatively, the side of the pad opposite the side with the adhesive carries fastener material, and the flexible strap is separate therefrom. A channel is present through the fastener material on either the pad, flexible strap or both to receive the catheter.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
183 words
A catheter support for securing a catheter to a living body comprising: an anchoring pad having a body compatible adhesive carried by one side thereof; a flexible strap comprising a layer of fastener material on one side thereof, a portion of said flexible strap being attached to a side of said anchoring pad; said fastener material comprising a plurality of spaced apart resilient and deformable curved plastic elements which are arranged in a planar array with equal spacing of elements in each row of the array and with every other row offset from an adjacent row; said fastener material on said portion of strap attached to said pad having a channel formed therethrough for receiving said catheter; said fastener material divided into an area on said anchoring pad and a remaining area on said strap separated by a hinge area separate from said channel; said flexible strap adapted to fold at said hinge area across said catheter in said channel to secure it to said pad when said remaining area of fastener material is pressed together with said area on said anchoring pad.
Claim 2
Dependent Claim
