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. A retainer for securing an elongated medical article, comprising:

a first member;

a second member which is pivotally coupled to the first member and movable between an open position and a closed position so as to form a channel when in the closed position;

a keeper having at least one bar and an operator lever, at least a portion of the operator lever being accessible from outside the channel when the second member is in the closed position, the bar deflecting towards the channel when the operator lever is actuated and the second member is in the closed position so as to allow the second member to pivot to the open position; and

a latch having a receptacle capable of accepting at least a portion of the bar when the second member is in the closed position.

2. A retainer as in claim 1, wherein the operator lever is angled with respect to the first member when the second member is in the closed position.

3. A retainer as in claim 1, wherein the operator lever is configured to deflect the bar inwardly when a downward force is applied to the operator lever.

4. A retainer as in claim 1, wherein the keeper and the second member are formed as a unitary piece.

5. A retainer as in claim 1, wherein the latch and the first member are formed as a unitary piece.

6. A retainer as in claim 1 further comprising a plurality of tangs and plurality of notches, the plurality of tangs being configured to be disposed in the plurality of notches when the second member is in the closed position.

7. A retainer as in claim 1, wherein the latch comprises at least one chamfered surface.

8. A retainer as in claim 7, wherein the at least one chamfered surface is configured to cause the bar to deflect inward as the second member is moved from the open to the closed position.

9. A retainer as in claim 1 further comprising a relief disposed so as to receive at least a portion of the operator lever when the second member is in the closed position.

10. A retainer for securing an elongated medical article, 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 latch 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 latch in order to move the cover from the closed to the open position.

11. A retainer as in claim 10, wherein the operator lever is angled with respect to the base when the cover is in the closed position.

12. A retainer as in claim 10, wherein the latch further includes 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.

13. A retainer as in claim 10, wherein the operator lever is configured to deflect the member inwardly when a downward force is applied to the operator lever.

14. A retainer as in claim 10, wherein the keeper and the cover are formed as a unitary piece.

15. A retainer as in claim 10, wherein the latch and the base are formed as a unitary piece.

16. A retainer as in claim 10 further comprising a plurality of tangs and a plurality of notches, the plurality of tangs being configured to be disposed in the plurality of notches when the cover is in the closed position.

17. A retainer as in claim 10, wherein the latch comprises at least one chamfered surface configured to cause the member to deflect inward as the cover is moved from the open to the closed position.

18. A retainer as in claim 10, wherein the cover and the base cooperate to define a channel when the cover lies in the closed position and are configured to receive at least a portion of the elongated medical article.

19. A securement system comprising:

a medical article including a branching site at which point an elongated body of the medical article separates into two elongated bodies; and

a retainer comprising;

a base,

a cover which is attached to the base, the base and cover being configurable to surround at least the branching site of the 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 contacting at least a portion of the latch so as to inhibit the cover from moving away from the base, and the latch accepting at least a portion of the bar when the cover and base surround the branching site, the keeper also including an operator lever that can be actuated by a medical attendant to deflect the bar of the keeper toward the secured medical article to disengage the bar from the receptacle of the latch in order to release the latch from the keeper.

20. A securement system as in claim 19, wherein the bar comprises at least one tang, the tang being disposed on one side of the bar and the secured medical article being disposed on the other side of the bar.
