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.

Claims

1-26. -26. (canceled)

27. An anchoring system for securing a Y-site of an elongated medical article to the skin of a patient comprising:

a retainer including a first member and a second member disposed relative to each other to define a channel to receive portions of the medical article at the Y-site, the channel being configured to surround at least one of the portions of the elongated medical article; and

an anchor pad disposed generally between the channel and the skin of the patient, the retainer being rotatable relative to the anchor pad so as to allow the retained medical article to swivel with respect to the patient, wherein the Y-site at least partially lies within the channel when the medical article is placed within the retainer.

28. The anchoring system of claim 27, wherein at least a portion of the channel tapers.

29. An anchoring system comprising:

a medical article having an elongated body with a branching site at which point the elongated body separates into two elongated sections, at least a portion of the medical article extending proximal of the branching site; and

a retainer defining a channel and an abutment surface, the channel being configured to retain at least the branching site of the medical article, the retainer having at least a first opening, a second opening, and a third opening, the first opening being sized to receive the proximal portion of the medical article, the second opening being configured to receive one of the two elongated sections, and the abutment surface being disposed between the first opening and the third opening so as to inhibit movement of the medical article in a first direction when the branching site is retained by the retainer.

30. The anchoring system of claim 29, wherein the abutment surface is disposed between the second opening and the third opening, the third opening being configured to receive one of the two elongated sections, the abutment surface being disposed between the two elongated sections of the medical article with the branching site retained by the retainer, wherein the first direction is in a distal direction.

31. The anchoring system of claim 29, wherein the abutment surface is disposed between the first opening and the second opening, the abutment surface being disposed between one of the two elongated sections and the proximal portion of the medical article with the branching site retained by the retainer, wherein the first direction is in a proximal direction.

32. The anchoring system of claim 29, wherein axes through the second opening and the third opening are skewed relative to each other.

33. An anchoring system for securing an elongated medical article having a Y-site to the skin of a patient, comprising:

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

a mounting base attached to the anchor pad and being more rigid than the flexible anchor pad; and

a retainer being rotatable relative to the mounting base and comprising a channel configured to generally surround at least a portion of the Y-site when at least the portion of the Y-site lies within the channel, the retainer being more rigid that the elongated medical article.

34. The anchoring system of claim 33, wherein the retainer is rotatably connected to the mounting base by a rotatable coupling.

35. The anchoring system of claim 34, wherein the rotatable coupling is formed by a generally circular member affixed to the mounting base and a receptacle formed in the retainer, the receptacle receiving the circular member which defines a rotational axis for the retainer.

36. The anchoring system of claim 35, wherein the circular member defines at least one bearing surface about which the retainer rotates.

37. The anchoring system of claim 36, wherein the at least one bearing surface includes a peripheral rim.

38. The anchoring system of claim 33, wherein the retainer includes three openings to receive the three sections of the Y-site.

39. An anchoring system for securing a Y-site of an elongated medical article to the skin of a patient comprising:

a retainer including a channel to receive portions of the medical article at the Y-site, the channel being configured to surround at least one of the portions of the elongated medical article; and

an anchor pad disposed generally between the channel and the skin of the patient, the retainer being rotatable relative to the anchor pad so as to allow the retained medical article to swivel with respect to the patient, wherein the Y-site at least partially lies within the channel when the medical article is placed within the retainer.

40. An anchoring system for securing a Y-site of an elongated medical article to the skin of a patient comprising:

a retainer including a channel to receive at least one portion of the medical article at the Y-site, the channel being configured to surround at least one of the portions of the elongated medical article; and

an anchor pad disposed generally between the channel and the skin of the patient, the retainer being rotatable relative to the anchor pad so as to allow the retained medical article to swivel with respect to the patient, wherein the Y-site at least partially lies within the channel when the medical article is placed within the retainer.
