Abstract

An anchoring system secures a catheter to the body of a patient and arrests axial movement of the catheter without meaningfully impairing fluid flow through the catheter. The anchoring system includes an anchor pad that adheres to the patient'"'"'s skin and supports a retainer. The retainer includes interacting structure with a cooperating keeper and latch that releasably moves the retainer between an open and a closed position. When in the open position, the retainer can receive a portion of the catheter and be subsequently moved to the closed position. The retainer further includes one or more retention mechanisms that inhibit axial movement of the catheter relative to the retainer when the catheter is secured therein. In one mode, the retainer includes interacting structure with a keeper and latch. The keeper selectively cooperates with the latch to secure the retainer in a closed position where the cover is generally over to the base. In another mode, the anchoring system includes a mount that allows the retainer to rotate 360° relative to the anchor pad.

13. An anchoring system as in claim 12, wherein the projection has a length that is greater than a depth of the recess.

14. The anchoring system as in claim 1, wherein the retainer is rotatably attached to the anchor pad.

15. An anchoring system for securing an elongated medical article having at least one branching site to the skin of a patient, comprising:

an anchor pad having an upper surface and a lower surface, at least a portion of the lower surface formed with an adhesive layer;

a retainer rotatably attached to the upper surface of the anchor pad, and comprising a base, post, and a cover pivotally coupled to the base and moveable between an open position and a closed position, the cover and the base cooperating to define at least one channel when the cover lies in the closed position, the channel being configured to receive at least a portion of the elongated medical article, and the post being coupled to one of said base and said cover and being arranged on said retainer so as to at least partially lie between said cover and said base when the cover is in the closed position and fall within the branching site at least when the medical article is placed within the retainer and the cover is in the closed position; and

at least one retainer member projecting into the channel and arranged to be capable of engaging a portion of the medical article to inhibit axial movement of the medical article through the channel.

16. The anchoring system as in claim 15, wherein at least a portion of the channel includes a width, as measured in a lateral direction, which tapers in size.

17. The anchoring system as in claim 15, further comprising a latching mechanism operable between the base and the cover to secure the cover to the base when the cover is in the closed position.

18. The anchoring system as in claim 15, wherein the post is disposed within the receiving space.

19. The anchoring system as in claim 15 additionally comprising a mounting base fixed to the upper surface of the anchor pad, and a rotatable coupling connecting the mounting base to the base of the retainer.

20. An anchoring system as in claim 19, wherein the rotatable coupling is formed by a mounting post affixed to the mounting base and a receptacle formed in the retainer base, the receptacle receiving the mounting post which defines a rotational axis for the retainer.

21. An anchoring system for securing an elongated medical article having at least one Y-site to a patient, comprising:

an anchor pad having an upper surface and a lower surface; and

a retainer mounted on the upper surface of the anchor pad and capable of receiving a portion of the medical article, the retainer including;
