Abstract

A medical article securement device holds a medical article in position upon the body of a patient and can be used to inhibit lateral and longitudinal motion of the medical article. The securement device includes a retainer with a base and at least one post, and at least one cap. The cap is attached to the base of the retainer by a flexible connection, and can be placed into either a covered or uncovered configuration with respect to the post. The cap includes a recess which can receive a protrusion at the end of the post of the retainer. By placing the post through an appropriate opening in the medical article to be retained and then securing the medical article to the retainer by placing the cap into the covered position over the post, longitudinal and lateral motion of the medical article is inhibited.

Claims

1. A securement system comprising:

a medical article having a central lumen and a side lumen extending outwardly from the central lumen;

a retainer having a base and an adhesive layer;

two posts disposed upon the base of the retainer and extending away from a side of the base of the retainer opposite the side of the base of the retainer to which the adhesive layer is disposed;

a receiving space disposed on the base and between the two posts, the receiving space receiving at least a portion of the central lumen of the medical article;

two caps covering the two posts, each cap having at least two configurations including a covered configuration in which a portion of the post is disposed within the cap, and an uncovered configuration in which a portion of the post is not disposed within the cap; and

two flexible connectors connecting the base of the retainer to the two caps, at least one of the two flexible connectors and at least one of the two posts forming a side channel therebetween at least when the post is disposed within the cap, the side channel surrounding at least a portion of the side lumen of the medical article, the side channel and receiving space being disposed on different sides of the at least one of the two posts.

2. The device of claim 1, wherein each post comprises a shaft and a protrusion disposed near the end of the shaft away from the base of the retainer.

3. The device of claim 2, wherein each cap comprises a recess configured to receive the protrusion of one of the posts.

4. The device of claim 3, wherein the protrusion is held within the recess of the cap in the covered configuration by a snap-fit arrangement between the protrusion and the cap.

5. The device of claim 3, wherein the each cap further comprises a collar disposed at the end of the recess and the size of the an opening of the collar is smaller than a dimension of the protrusion of the post that is to be received within the recess of each cap.

6. The device of claim 1 further comprising an anchor pad having an upper surface and a lower surface, the retainer being disposed upon the upper surface of the anchor pad and the adhesive layer being disposed upon the lower surface of the anchor pad.

7. The device of claim 1, wherein the at least one of the flexible connectors forms a loop so as to extends for at least 180 degrees around the portion of the side lumen of the medical article.

8. A releasable medical line securement system comprising:

a medical article having a first tubing section extending in a longitudinal direction and a second tubing section coupled with the first tubing section, the second tubing section extending in an outward direction from the first tubing section;

a retainer having a base and a plurality of posts disposed upon the base of the retainer and extending away from the base, each post comprising a shaft and an enlarged head disposed near the end of the shaft, and at least one cap covering each post, each cap comprising a recess configured to receive the enlarged head of one of the plurality of posts, the each cap having at least two configurations including a covered configuration in which the enlarged head of the post is at least partially disposed and secured within the recess of the cap, and an uncovered configuration in which the enlarged head of the post is not disposed within the recess of the cap; and

at least one flexible connection connecting one of the at least one cap to the base, the at least one flexible connection forming a loop at least when the corresponding post is disposed within the at least one cap, the second tubing section of the medical article extending through the loop away from the first tubing section when the corresponding post is disposed within the at least one cap.

9. The releasable medical line securement system of claim 8, wherein the head is held within the recess of the at least one cap in the covered configuration by a snap-fit arrangement between the head of the post and the cap.

10. The releasable medical line securement system of claim 8, wherein the at least one cap further comprises a collar disposed at an open end of the recess and the size of an opening of the collar is smaller than a lateral dimension of the head of the post that is to be received within the recess of the cap.

11. The releasable medical line securement system of claim 8 further comprising an anchor pad having an upper surface and a lower surface, the retainer being disposed upon the upper surface of the anchor pad and an adhesive layer being disposed upon the lower surface of the anchor pad.

12. The releasable medical line securement system of claim 8, wherein the at least one cap of the retainer further comprises a tab that extends from the cap to provide a surface upon which a medical practitioner may press to remove the cap from the post when the cap is in the covered configuration.

13. The releasable medical line securement system of claim 8, wherein the base, the at least one cap, and the plurality of posts of the retainer are integrally formed.

14. A device for securing a medical article to a patient, the medical article having a first lumen and a second lumen, the device comprising:

a retainer having a base and an adhesive layer;

a first post and a second post disposed upon the base of the retainer and extending away from a side of the base of the retainer opposite the side of the base of the retainer to which the adhesive layer is disposed, a receiving space being defined between the first post and the second post; and

at least one cap configured to cover the first post, the at least one cap being attached to the base of the retainer by a flexible connection,

wherein the at least one cap, the flexible connection, and the first post together form a channel which the second lumen of the medical article extends through when a recess of the at least one cap receives a portion of the first post, and wherein the first lumen of the medical article extends through the receiving space.

15. The device of claim 14, wherein the channel is configured to inhibit at least longitudinal and lateral movement of the medical article, and wherein the receiving space is configured to inhibit at least lateral movement of the medical article.

16. The device of claim 14, wherein the at least one cap has at least two configurations including a covered configuration in which a portion of the first post is disposed within the recess of the cap and an uncovered configuration in which a portion of the first post is not disposed within the recess of the cap.

17. The device of claim 14, wherein the flexible connection forms a loop so as to extend for at least 180 degrees around the portion of the medical article.

18. The device of claim 14, wherein the base, the at least one cap, the first post, and the second post of the retainer are integrally formed.

19. The device of claim 14, wherein the flexible connection is integral with the base.
