Dialysis catheter anchoring system
First Claim
1. A catheterization system comprising:
- a catheter including a branching site at which point the elongated body of the catheter separates into two elongated bodies and also including a winged catheter portion disposed proximal of the branching site;
an anchoring system comprising an anchor pad and a retainer, the anchor pad comprising an upper surface and a lower surface, at least a portion of the lower surface formed with an adhesive layer, and the retainer comprising a base, a cover and an adhesive spot, the base having a substantially disc shaped lower surface which is attached to the upper surface of the anchor pad, and 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 a portion of the catheter including the branching site, and the adhesive spot being disposed upon the channel such that at least when the cover is in the closed position, the adhesive spot lies in contact with both the retainer and a portion of the catheter and inhibits motion of the catheter within the channel of the retainer, the retainer further comprising at least one retainer member projecting into the channel and arranged to engage a portion of the catheter to inhibit axial movement of the catheter through the channel, and the retainer further comprising a latching mechanism operable between the base and the cover to selectively secure the cover to the base when the cover is in the closed position.

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.

1. A catheterization system comprising:
-
a catheter including a branching site at which point the elongated body of the catheter separates into two elongated bodies and also including a winged catheter portion disposed proximal of the branching site;
an anchoring system comprising an anchor pad and a retainer, the anchor pad comprising an upper surface and a lower surface, at least a portion of the lower surface formed with an adhesive layer, and the retainer comprising a base, a cover and an adhesive spot, the base having a substantially disc shaped lower surface which is attached to the upper surface of the anchor pad, and 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 a portion of the catheter including the branching site, and the adhesive spot being disposed upon the channel such that at least when the cover is in the closed position, the adhesive spot lies in contact with both the retainer and a portion of the catheter and inhibits motion of the catheter within the channel of the retainer, the retainer further comprising at least one retainer member projecting into the channel and arranged to engage a portion of the catheter to inhibit axial movement of the catheter through the channel, and the retainer further comprising a latching mechanism operable between the base and the cover to selectively secure the cover to the base when the cover is in the closed position. - View Dependent Claims (2)

3. An anchoring system for securing an elongated medical article to the skin of a patient, comprising:
-
an anchor pad having an upper surface and a lower surface, at least a portion of the lower surface formed with an adhesive layer;
a retainer attached to the upper surface of the anchor pad, and comprising a base, a cover and an adhesive spot, the base having a substantially disc shaped lower surface which is attached to the upper surface of the anchor pad, and 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 a portion of the elongated medical article, and the adhesive spot being disposed upon the channel such that at least when the cover is in the closed position, the adhesive spot lies in contact with both the retainer and a portion of the medical article and inhibits motion of the medical article within the channel of the retainer;
at least one retainer member projecting into the channel and arranged to engage a portion of the medical article to inhibit axial movement of the medical article through the channel; and
a latching mechanism operable between the base and the cover to selectively secure the cover to the base when the cover is in the closed position. - View Dependent Claims (4, 5)

6. A retainer for securing an elongated medical article to an anchor pad disposed upon the skin of a patient, comprising:
-
a base;
a cover which is pivotally coupled to the base and movable between an open and a closed position; and
a latching mechanism operable between the base and the cover to selectively secure the cover to the base when the cover is in the closed position, the latching mechanism including a keeper and a latch, the keeper having at least one member capable of interengaging with at least a portion of the base, and the latch having a recess which accepts at least a portion of the member when the cover is in the closed position, the keeper also including an operator lever that can be actuated by the fingertip of a medical attendant to deflect the member of the keeper inwardly to disengage the member from the recess of the latch in order to move the cover from the closed to the open position, the latch also including a relief within which the operator lever lies when the latch is in the closed position and which allows the member to deflect inward as the cover is moved from the open to the closed position.

7. 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, a compressible member and a retaining 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 such that at least one branch of the medical article lies to each side of the retaining member;
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.
