Abstract

An anchoring system for securing a catheter to a patient includes an anchor pad and a retainer. The retainer is supported by the anchor pad and may include a base and a cover. A groove upon the base can be arranged to receive a branching site of a catheter where the lumens merge distal to the insertion site. One or more posts may also protrude from the base to the cover at a position disposed between the two distal branches of the catheter. The cover closes over the base securing the branching site between the groove and the posts. The contact between the retainer and catheter thereby inhibits inadvertent motion of the catheter upon the patient. A latch mechanism may be disposed upon the retainer to maintain the cover in a closed position over the branching site of the catheter on the base.

Claims

1. A catheter securement device, comprising:

a catheter;

an anchor pad having an adhesive layer disposed on at least a portion thereof;

a retainer including a channel configured to retain a portion of the catheter, the portion of the catheter comprising a branched section, the retainer comprising a first portion hingedly attached to a second portion, moveable between an open position and a closed position, the first portion including two posts and the second portion including two posts, the first portion posts configured to engage the second portion posts so as to form a portion of a distal surface of the retainer when the retainer is in the closed position; and

a latching mechanism configured to releasably secure the first and second portion in the closed position, the latching mechanism including;

at least one moveable keeper;

an operator lever; and

at least one latch post disposed between a of the channel wall and the at least one moveable keeper, and designed to engage an outer surface of the wall to prevent over-deflection of the at least one moveable keeper toward the portion of the catheter when a force is applied to the operator lever.

2. The catheter securement device according to claim 1, wherein the second portion posts are configured to engage the portion of the catheter so as to restrict movement of the catheter in at least a longitudinal direction.

3. The catheter securement device according to claim 1, wherein the retainer is rotatably coupled to the anchor pad.

4. The catheter securement device according to claim 1, wherein the posts on the first portion and the posts on the second portion define three openings in the distal surface of the retainer when the retainer is in the closed position.

5. The catheter securement device according to claim 1, wherein the retainer is composed of polypropylene.

6. The catheter securement device according to claim 1, wherein the first and second portions include a plurality of protrusions.

7. The catheter securement device according to claim 6, wherein the plurality of protrusions are positioned opposite one another.

8. The catheter securement device according to claim 6, wherein the plurality of protrusions inhibit longitudinal movement of the catheter.

9. The retainer according to claim 1, further comprising directional marks visible to a user when the retainer is in both the open and closed positions.

10. The retainer according to claim 9, wherein the directional marks are arrows.

11. The retainer according to claim 9, wherein the directional marks are on both a top and bottom of the retainer.

12. The retainer according to claim 1, wherein the at least one latch post prevents impingement of the portion of the catheter when a force is applied to the operator lever.

13. The retainer according to claim 1, wherein engagement between the at least one latch post and the outer surface of the wall resists bowing of at least one of the first and second portions of the retainer.

14. The retainer according to claim 1, wherein engagement between the at least one latch post and the outer surface of the wall resists bowing of at least one of the first and second portions of the retainer when a force is applied to the operator lever.

15. The retainer according to claim 1, wherein the at least one latch post is designed to prevent a deflecting force from traveling along a length of at least one of the first and second portions of the retainer.
