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.

Claims

1. An anchoring system comprising:

a medical article having an elongated body extending about a longitudinal axis; and

a retainer comprising,

a base,

a cover having first and second longitudinal sides, the cover being pivotally coupled to the base and being 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 body of the medical article, wherein the medical article extends beyond the first and second longitudinal sides of the cover when the medical article is placed within the retainer, and

an adhesive spot disposed on the retainer at a location to cooperate with the medical article to provide an adhesive force so as to resist movement of the medical article relative to the retainer in at least a direction that is generally normal to a surface of the adhesive spot.

2. The anchoring system of claim 1, wherein a portion of the base extends beyond the cover in a longitudinal direction when the cover lies in the closed position.

3. The anchoring system of claim 1, wherein a portion of the base extends beyond the cover in a lateral direction when the cover lies in the closed position.

4. The anchoring system of claim 1, wherein a portion of the cover extends beyond the base in a longitudinal direction when the cover lies in the closed position.

5. The anchoring system of claim 1, wherein a portion of the cover extends beyond the base in a lateral direction when the cover lies in the closed position.

6. The anchoring system of claim 1, wherein the adhesive spot is disposed on the cover.

7. The anchoring system of claim 1, wherein the adhesive spot is disposed on the base.

8. A retainer for a medial article, the retainer comprising:

a base;

a cover being pivotally coupled to the base and being 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 a medical article, wherein the cover is configured such that the medical article extends axially beyond the cover when the medical article is placed within the retainer; and

an adhesive spot disposed on the retainer at a location to cooperate with the medical article to provide an adhesive force so as to resist movement of the medical article relative to the retainer in at least a direction that is generally normal to a surface of the adhesive spot.

9. The retainer of claim 8, wherein a portion of the base extends beyond the cover in a longitudinal direction when the cover lies in the closed position.

10. The retainer of claim 8, wherein a portion of the base extends beyond the cover in a lateral direction when the cover lies in the closed position.

11. The retainer of claim 8, wherein a portion of the cover extends beyond the base in a longitudinal direction when the cover lies in the closed position.

12. The retainer of claim 8, wherein a portion of the cover extends beyond the base in a lateral direction when the cover lies in the closed position.

13. The retainer of claim 8, wherein the base and the cover extend with equal lengths when the cover lies in the closed position.

14. The retainer of claim 8, wherein the adhesive spot is disposed on the cover.

15. The retainer of claim 8, wherein the adhesive spot is disposed on the base.

16. 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 sections and forms a valley of a Y-site therebetween, a portion of the medical article located proximal to the branching site having a cross-sectional shape; and

a retainer defining a channel and an abutment surface, the channel being configured to receive at least the branching site of the medical article, the channel having a first opening, a second opening, and a third opening, the first opening being sized at least as large as the cross-sectional shape of the proximal portion of the medical article, the second opening being configured to accept one of the two elongated sections, and the abutment surface being located between the second and third openings when the branching site is located with the channel.

17. The anchoring system of claim 16, further comprising an adhesive spot disposed on the retainer so as to form an adhesive force in at least a direction that is generally normal to a surface of the adhesive spot.

18. The anchoring system of claim 16, wherein at least a portion of the abutment surface has a curved surface, the curved surface inhibiting movement of the medical article in at least a first direction.

19. The anchoring system of claim 16, wherein at least a portion of the channel has a tapering shape.

20. The anchoring system of claim 19, wherein the tapering shape of the channel generally matches a tapering shape of at least a portion of the retained portion of the medical article to inhibit longitudinal movement of the retained medical article in a first direction when the retained portion of the medical article is inserted into the channel.
