Dialysis catheter anchoring system
First Claim
1. An anchoring system for a medical article comprising:
- a medical article having an elongated body at least a portion of the medical article having a cross-sectional shape;
a retainer comprising a base, a cover and an adhesive spot, the cover being pivotally coupled to the base and movable between an open position and a closed position, the cover and the base cooperating to define a channel when the cover lies in the closed position, the channel being configured to receive at least the portion of the medical article and being sized at least as large as the cross-sectional shape of the portion of the medical article, and the adhesive spot being disposed upon the channel so as to form an adhesive bond with the medical article to provide an adhesive force in at least a transverse direction when the medical article is in contact with the adhesive spot.

Abstract
An anchoring system for securing a dialysis catheter to a patient comprises an anchor pad and a retainer. The anchor pad is attached to the skin of the patient by an adhesive layer 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 and a cover and a adhesive spot. A groove upon the base is arranged to receive a Y-site portion of a dialysis catheter where the lumens merge distal to the insertion site. A post 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 is disposed upon the retainer to maintain the cover in a closed position over the Y-site of the catheter on the base.

18. A method of releaseably anchoring an elongated medical article onto a patient which permits the medical article to be retained in the same position relative to the patient, comprising:
-
providing an anchoring device which provides an adhesive lower surface, and a retainer comprising a base, a cover, and an adhesive spot, the base further comprising at least a groove, and the base and the cover together forming a channel when the cover is secured in position over at least a portion of the base; inserting at least a portion of the medical article into the groove; positioning the cover over at least a portion of the groove; securing the cover in a position overlying the covered portion of the groove to press a retained portion of the medical article against the adhesive spot to provide an adhesive force in at least a transverse direction between the adhesive spot and the retained portion of the medical article; and securing the anchoring device to the skin of the patient via the adhesive lower surface of the anchoring device.
