Dialysis catheter anchoring system
First Claim
1. An anchoring system for a medical article comprising:
- a medical article having an elongated body and a branching site at which point the elongated body separates into two elongated bodies;
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 and being configured to receive at least the branching site of the medical article, and the adhesive spot being disposed upon the channel such that the adhesive spot lies in contact with the retainer and the medical article when the cover is in the closed position and inhibits motion of the medical article relative to the retainer, the retainer further comprising a latching mechanism to releasably secure the cover in the closed position upon the base.

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.

7. A retainer for securing an elongated medical article, comprising:
-
a base;
a cover which is attached to the base, the base and cover being configurable to surround a portion of the elongated medical article; and
a latching mechanism operable between the base and the cover to releasably secure the cover to the base, the latching mechanism including a keeper and a latch, one of the keeper and the latch being disposed upon the base and the other of the keeper and the latch being disposed upon the cover, the keeper having at least one bar capable of interengaging with at least a portion of the latch, and the latch having a receptacle which accepts at least a portion of the bar when the cover and base surround the portion of the elongated medical article, the keeper also including an operator lever that can be actuated by the fingertip of a medical attendant to deflect the bar of the keeper toward the hinge to disengage the bar from the receptacle of the latch in order to release the latch from the keeper.

8. A retainer for securing an elongated medical article having a branching site, the medical article also having a winged portion disposed proximal of the branching site, the retainer comprising:
-
a base;
a cover movably coupled to the base and having an open configuration and a closed configuration, the cover and the base cooperating to define a channel in the closed configuration and being configured to receive at least a portion of the medical article, the channel being dimensioned such that when the winged portion of the medical article is positioned proximal to the cover and the cover is in the closed configuration, the winged portion of the medical article is inhibited from moving distally into the channel. - View Dependent Claims (9, 10)

11. A method of releaseably anchoring an elongated medical article including a branching site 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 a compressible member, 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 the branching site 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 compressible member to provide adhesion between the compressible member 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.
