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. An anchoring system for securing a medical article including at least one aperture to a patient, comprising:

an anchor pad having a first surface and a second surface,

a retainer mounted on the first surface of the anchor pad for receiving a portion of the medical article, the retainer having a base attached to the first surface and a plurality of posts that extend from the base, at least one of the plurality of posts being configured to fit within the at least one aperture; and

at least one clip extending from the base having an interior configured to receive at least a portion of the medical device.

2. An anchoring system as in claim 1, wherein the retainer includes two posts, and each of the posts having a shaft attached to and extending from the base, and each of the posts include a securing portion that is sized and configured to permit engagement between a portion of the medical article and the shafts and to inhibit unintentional disengagement of the portion of the medical article from the shaft once engaged.

3. An anchoring system as in claim 2, wherein the securing portion of each post includes a head, at least a portion of the head having a perimeter size larger than a perimeter size of the corresponding shaft.

4. An anchoring system as in claim 3, wherein one of the posts has a head that further comprises a radially extended portion that faces away from the head of the other post.

5. An anchoring system as in claim 4, wherein the extended portion is angled toward the retainer base.

6. An anchoring system as in claim 5, wherein the extended portion has a taper directed toward an outer end of the extended portion.

7. An anchoring system as in claim 3, wherein at least one of the posts has a head with a blunt rounded end distal of the retainer.

8. An anchoring system as in claim 3, wherein at least a portion of each of the heads has a generally flat underside surface to inhibit unintentional disengagement of the medical article from the post once engaged.

9. An anchoring system as in claim 2, wherein the securing portion of each post includes a bulb, at least a portion of the bulb having a perimeter size larger than a perimeter size of the corresponding shaft.

10. An anchoring system as in claim 9, wherein one of the posts has a bulb that further comprises a radially extended portion that faces away from the bulb of the other post.

11. An anchoring system as in claim 10, wherein the extended portion is curved toward the retainer base and has a taper directed toward an outer end of the extended portion to form a hook that further assists in engagement between the medical article and the post and inhibits unintentional disengagement of the medical article from the post once engaged.

12. An anchoring system as in claim 1, wherein the clip has a hook portion that extends toward the retainer and narrows an entranceway into an interior of the clip to inhibit unintentional disengagement of the medical article from the clip once engaged.

13. An anchoring system as in claim 12, wherein the hook portion is so configured to narrow the entranceway to a transverse height that is less than three-quarters of the transverse height of the engaged portion of the medical article.

14. An anchoring system as in claim 13, wherein the hook portion is so configured to narrow the entranceway to a transverse height that is about one-half of the transverse height of the engaged portion of the medical article.
