Catheter anchoring system
First Claim
1. A securement device for attaching a medical article to a patient, the medical article having a generally elongated body and a side member that projects away from the body, the securement device comprising:
- a retainer having a first channel portion and a second channel portion, the channel portions being disposed about a longitudinal axis of the retainer and having a length measured in a direction parallel to the longitudinal axis of the retainer, the retainer directly contacting the medical article along at least a substantial portion of the longitudinal lengths of the first and second channel portions, each channel portion curving about the longitudinal axis of the retainer by greater than 180°
, the first channel portion being spaced from the second channel portion, at least part of the first channel portion being wider, as measured perpendicularly to the longitudinal axis of the retainer, than another part of the first channel portion, the combined longitudinal lengths of the first and second channel portions being larger than a distance separating the first and second channel portions along the longitudinal axis of the retainer, said distance substantially equaling a dimension of the side member of the medical article as measured parallel to the longitudinal axis of the retainer;
a base, the retainer being coupled to the base so as to move in a longitudinal direction relative to the base; and
an interlocking mechanism, at least a portion of the interlocking mechanism being movable in a direction perpendicular to the longitudinal direction so as to limit the retainer from moving relative to the base.

Abstract
A catheter anchoring system is provided to securely anchor to a patient'"'"'s skin a catheter and fluid supply tube interconnection. The anchoring system comprises a retainer configured to receive a catheter adaptor in a variety of positions. The adaptor interconnects the catheter and the fluid supply tube. In one embodiment the adaptor has a radial recess that circumscribes the adaptor. The anchoring system additionally includes a flexible, adhesive anchor pad which can supports a tube clip, as well as the retainer. The retainer includes a channel that is configured to receive the adaptor in a snap-fit manner. The retainer also includes a plurality of laterally arranged projections that extend from a channel wall and into a channel. Each radial recess is sized to receive and to capture at least a portion of the projection of the retainer so as to inhibit the adaptor from moving within the channel.

15. A securement device for attaching a medical article to a patient, the medical article having a generally elongated body and a side member that projects away from the body, the securement device comprising:
-
an anchor pad; a base affixed to the anchor pad; and a retainer movably coupled to the base so as to move in a longitudinal direction relative to the base, the retainer comprising at least first and second channel portions arranged side-by-side along a longitudinal axis of the retainer with at least one gap occurring between the channel portions, the gap having a dimension in a direction parallel to the longitudinal axis of the retainer that generally matches a dimension of the side member of the medical article as measured parallel to the longitudinal axis of the retainer; and an interlocking mechanism, at least a portion of the interlocking mechanism being movable in a direction perpendicular to the longitudinal direction so as to limit the retainer from moving relative to the base. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A securement device for attaching a medical article to a patient, the medical article having a generally elongated body and a side member that projects away from the body, the securement device comprising:
-
a retainer including first and second channel portions that each curve about a longitudinal axis of the retainer by more than 180°
, the retainer directly contacting the medical article along at least a substantial portion of the longitudinal lengths of the first and second channel portions, each channel portion having an opening that extends along the longitudinal axis of the retainer, the first and second channel portions being disposed apart with at least one gap therebetween, a distance across the gap as measured in a direction parallel to the longitudinal axis of the retainer being substantially the same as a dimension of the side member of the medical article, which is measured along the longitudinal axis of the retainer, and being less than the combined lengths of the first and second channel portions as measured parallel to the longitudinal axis of the retainer;a base, the retainer being coupled to the base so as to move in a longitudinal direction relative to the base; an interlocking mechanism, at least a portion of the interlocking mechanism being movable in a direction perpendicular to the longitudinal direction so as to limit the retainer from moving relative to the base; and a flexible anchor having a bottom surface with an adhesive for attaching the anchor to the patient, the base being coupled to the anchor. - View Dependent Claims (31, 32, 33, 34, 35, 36)
