Abstract

An anchoring system includes a simply-structured device which permits a portion of a catheter or similar medical article to be easily anchored to a patient, desirably without the use of tape or needles and suturing. The anchoring system desirably includes a retainer and an anchor pad. The retainer is sized and configured to accept and retain a section of a catheter within the anchoring system and desirably includes a pair of posts and a clip. The posts are sized and configured to releasably accept holes formed in the catheter or catheter fitting. The clip is sized and configured to releasably accept a portion of the catheter. The anchor pad secures the retainer to a patient'"'"'s skin.

Claims

1. A securement system comprising:

a medical article having a fitting that includes a pair of laterally extending wings; and

a securement device comprising;

a mounting layer having a mounting surface at least partially covered by an adhesive for attaching the securement device to the body of the patient;

a base surface accessible from an opposite side of the mounting layer; and

first and second retention surfaces each being distanced in a transverse direction from the base surface by a sufficient distance so as to define a receiving space therebetween, the receiving space being of a size so as to releasably accept at least a portion of the laterally extending wings, the first and second retention surfaces being arranged relative to each other so as to define an entranceway into the receiving space along a longitudinal axis, the entranceway having a lateral width less than a width of the fitting.

2. The securement device of claim 1 further comprising first and second inverted L-shaped clips, wherein the first retention surface is a first portion of a clip interior of the first inverted L-shaped clip and the second retention surface is a first portion of a clip interior of the second inverted L-shaped clip.

3. The securement device of claim 2, wherein the first inverted L-shaped clip interior comprises a second portion extending transversely toward the base surface and the second inverted L-shaped clip interior comprises a second portion extending transversely toward the base surface, and wherein a lateral distance between the second portion of the clip interior of the first L-shaped clip and the second portion of the clip interior of the second L-shaped clip is greater than the lateral width of the entranceway.

4. The securement device of claim 3, wherein the lateral distance between the second portions of the first and second inverted L-shaped clips is greater than a transverse height of the receiving space.

5. The securement device of claim 3, wherein the lateral distance between the second portions of the first and second inverted L-shaped clips is less than the width of a body of the medical article.

6. The securement device of claim 1, wherein the distance between the first and second retention surfaces and the base surface is less than a transverse height of at least a portion of the medical article so that movement of the retained portion of the medical article is inhibited by a holding effect provided by the first and second retention surfaces when said portion of the medical article is placed within the receiving space.

7. The securement device of claim 1, additionally comprising at least one post disposed on the base surface and extending in a transverse direction, the first post having a securing portion arranged toward an outer end of the first post.

8. The securement device of claim 7, wherein the post comprises a shaft, and wherein the securing portion includes a head, at least a portion of the head having a perimeter sized larger than a perimeter size of the shaft.

9. The securement device of claim 7, additionally comprising another post being disposed on the base surface and having a securing portion arranged toward an outer end of the said post.

10. The securement device of claim 9, further comprising first and second inverted L-shaped clips, wherein the first retention surface is a first portion of a clip interior of the first clip and the second retention surface is a first portion of a clip interior of the second clip, and wherein the receiving space between the two clips lies along a line that substantially bisects a line extending between the two posts.

11. The securement device of claim 10, wherein the base surface, posts, and clips are all parts of a unitary structure.

12. A securement system comprising:

a medical article having an elongated body and a pair of laterally extending surfaces; and

a securement device comprising;

an anchor pad having a mounting surface at least partially covered by an adhesive layer for attaching the securement device to the patient'"'"'s body, and a receiving surface oriented so as to face away from the patient'"'"'s body, the receiving surface including a longitudinally extending section along which at least a portion of the medical article lies when secured by the securement device; and

a pair of retention surfaces being spaced in a transverse direction from the receiving surface by a sufficient distance to releasably accept at least a portion of the laterally extending surfaces between the pair of retention surfaces and the receiving surface, inner edges of the pair of retention surfaces defining an entranceway along a longitudinal axis, the pair of retention surfaces and the receiving surface together defining a receiving space, the receiving space having a lateral dimension which is greater than a lateral dimension of the entranceway, wherein at least a portion of the laterally extending surfaces of the medical article is retained within the receiving space.

13. The securement device of claim 12, wherein the retention surfaces are interior portions of clip comprising two inverted L-shaped clip members.

14. The securement device of claim 13, wherein a clip interior of one of the two inverted L-shaped clips faces the clip interior of the other inverted L-shaped clip.

15. The securement device of claim 12, wherein a lateral distance between a second portion of the clip interior of one of the two inverted L-shaped clips and a second portion of the clip interior of the other inverted L-shaped clip is greater than the lateral width of the entranceway.

16. The securement device of claim 15, wherein the lateral distance is greater than a transverse height of the receiving space at least when the medical article is secured within the receiving space.

17. The securement device of claim 12, wherein the distance between the first and second retention surfaces and the base surface is less than a transverse height of a retained portion of the medical article at least when the retained portion is not secured within the receiving space so that movement of the retained portion is inhibited by a holding effect provided by the first and second retention surfaces when the retained portion is secured within the receiving space.

18. The securement device of claim 12, additionally comprising at least a first post extending from said receiving surface, the first post having a securing portion arranged toward an outer end of the first post.

19. The securement device of claim 18, wherein the retention surfaces are portions of two clips, and wherein the receiving surface, post, and clips are part of a unitary structure.
