US 4,516,968 A · Catheter shield and method of use

Abstract

A catheter shield comprising a dome surrounded by a peripheral, skin engaging flange. The dome defines a cavity, has a hole for the catheter, and has a radial slit extending to the edge of the shield to aid in placement of the shield around the catheter. Vents may be provided in the shield. The shield is held in place by holding the shield against the skin, moderately tensioning the catheter, providing means for preventing relative longitudinal motion between the catheter and the shield, and then releasing the catheter so the elasticity of the catheter and of the body parts which anchor it pull and hold the shield in place against the skin. A second method for securing the shield entails positioning the shield around the catheter, pressing the shield firmly downward against the skin, and applying a tape strip with one of its edges firmly against the top of the shield. When the hand pressure on the shield is released, the compressed portion of the body beneath the shield tries to expand and force the shield outwardly. However, since the tape strip prevents relative longitudinal motion between the shield and the catheter, the shield cannot move outwardly relative to the catheter and is thus held in place against the skin by the catheter and tape strip.

Dependent claims

A catheter shield kit, wherein said kit comprises an elastic catheter adapted to enter a body through a catheter entrance site, wherein during use a portion of said catheter is anchored in said body, and wherein during use a portion of said catheter is outside said body and is under tension;

wherein said kit further comprises a catheter anchor means and a catheter shield comprising a relatively stiff shield dome defining a shield cavity, a peripheral shield flange extending at least partially around said shield dome, and a catheter shield hole in the top of said shield dome generally aligned with said catheter entrance site;
wherein said catheter shield hole is sized to be adapted to receive said catheter therethrough;
wherein said catheter shield, during use, is adapted to be placed with said shield flange against said body, with said catheter entrance site under said shield dome, and with said catheter extending through said catheter shield hole;
wherein said catheter anchor means, during use, are for securing at least one of said catheter and said catheter shield, and wherein said catheter anchor means, during use, are adapted to prevent longitudinal motion of said catheter shield away from said body with respect to said catheter;
and wherein, during use, said tension of said portion of said catheter outside said body is adapted to pull on said catheter anchor means to urge said catheter shield snugly against said body, thereby eliminating the need to use adhesive media on said body to secure said catheter shield to said body.
