DIALYSIS CATHETER ANCHORING SYSTEM

摘要

An anchoring system (10) for securing a dialysis catheter to a patient comprises an anchor pad (12) and a retainer (20). The anchor pad is attached to the skin of the patient by an adhesive layer (16) on one side of the pad. The retainer is disposed upon the surface of the anchor pad opposite the adhesive layer and includes a base (22) and a cover (24) and a adhesive spot. A groove (30) upon the base is arranged to receive a Y-site portion of a dialysis catheter (8) where the lumens merge distal to the insertion site. A post (78) also protrudes from the base to the cover at a position which will be disposed between the two distal branches of the dialysis catheter. The cover closes over the base, securing the Y-site between the groove and the post. Closing the cover also places at least a portion of the catheter in contact with the adhesive spot. This contact between the retainer, adhesive spot and catheter thereby inhibits inadvertent motion of the catheter upon the patient. A latch mechanism (80) is disposed upon the retainer to maintain the cover in a closed position over the Y-site of the catheter on the base.
