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 catheterization system for securing an elongated medical article to a patient, comprising:

an anchor pad having a first surface and a second surface, the second surface including an adhesive layer that covers at least a portion of 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 at least one post that extends from the base, the post having a securing portion arranged toward an outer end of the post; and

at least one clip formed on the retainer and sized and configured to engage at least a portion of the medical article.

2. An anchoring system as in claim 1, wherein the retainer includes a plurality of posts, and each of the posts has a shaft attached to and extending from the base, and the securing portion is sized and configured to permit engagement between a portion of the medical article and the shaft, 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 peripheral size larger than a peripheral size of the corresponding shaft.

4. An anchoring system as in claim 3, wherein a circumference of the head is larger than a circumference of the shaft.

5. An anchoring system as in claim 2, wherein the securing portion of at least one of the posts includes a hook portion.

6. An anchoring system as in claim 5, wherein the hook portion is spaced from the shaft.

7. An anchoring system as in claim 2, wherein at least two posts are spaced apart by sufficient distance to accommodate at least a portion of an elongated medical article between the posts.

8. An anchoring system as in claim 1, wherein the base, post and clips form a unitary structure.

9. An anchoring system for securing an elongated medical article to a patient, the medical article including at least one aperture, the anchoring system comprising an anchor pad and a retainer mounted to the anchor pad, the retainer including a first retention member being positioned generally upright relative to the anchor pad, and being configured to inserted through the corresponding aperture of the medical article, and a second retention member of which at least a portion is positioned to lie generally normal to the first retention member being spaced from the anchor pad by a distance so dimensioned to permit at least a section of the elongated medical article to be placed between the portion of the second retention member and the anchor pad.

10. An anchoring system as in claim 9, wherein the first retention member includes means for engaging a portion of the medical article about the aperture so as to inhibit unintentional disengagement of the medical article from the first retention member.

11. An anchoring system as in claim 9, wherein the second retention member includes means for inhibiting the section of the elongated medical article, which is received in an interposed position between the portion of the second retention member and the anchor pad, from dislodging from the interposed position.

12. An anchoring system as in claim 9, wherein the retainer comprises a third retention member that is positioned generally normal to the second retention member.

13. An anchoring system as in claim 12, wherein the third retention member lies generally parallel to the first retention member.

14. An anchoring system as in claim 13, wherein each of the first and third retention members includes a post having a stem and a securing portion.

15. An anchoring system as in claim 14, wherein the securing portion of each post includes a hooked section that extends toward the anchor pad, and the hooked section is spaced from the post.

16. An anchoring system as in claim 9, wherein the retainer includes a third retention member that is positioned generally parallel to the second retention member.

17. An anchoring system as in claim 9, in combination with an elongated medical article, wherein the aperture is formed is a wing section on the medical article.

18. A combination of claim 17, wherein the wing section is formed of a deformable material.

19. A method of securing a medical article to the body of a patient, the medical article including an elongated body with pliable wings extending from the body, each wing including at least one suture hole, the method comprising:

providing a retainer having at least first and second posts that are spaced apart and a clip that is positioned to the sides of the posts;

inserting the first posts into one of the suture holes;

stretching the wings to position the other suture hole over the second post;

hooking the wing over the second post while inserting the second post into the corresponding suture hole;

inserting a section of the elongated body within the clip so as to inhibit the elongated body from disengaging from the clip.

20. A method as in claim 19, additionally comprising adhering the retainer to the patient.
