Abstract

A universal securing device for holding catheters of various shapes and sizes and the like in place includes a base and cover. The cover may be connected to the base by a hinge which allows the cover to be lifted open or pushed down into a closed position, over a catheter fitting. The base may have locating elements configured and arranged to fit around catheter fittings of various sizes, and the locating elements prevent substantial movement of a catheter fitting and catheter in various dimensions. The cover may include capture elements which act to grip and compress the catheter fitting when the securing device is in a closed position, thus preventing substantial movement of a catheter fitting and catheter in various dimensions. The base may be attached to a patient with an adhesive pad attached to the bottom surface of the base.
