Catheter anchoring system
First Claim
1. A securement system comprising:
- a medical article having a generally elongated body including a first body portion and a second body portion, and a side member disposed between the first and second body portions and projecting away from the body; and
a retainer having a first channel portion and a second channel portion, the first and second channel portions defining an inner channel surface, 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 inner channel surface contacting the first and second body portions of 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° and
defining an abutment surface, each abutment surface extending generally perpendicular to the longitudinal axis and together defining a slot between the first and second channel portions, the slot receiving the side member of the medical article with at least a portion of the side member projecting in a transverse downward direction below the inner channel surface of the retainer, a distance measured between the abutment surfaces along the longitudinal axis being substantially equal to the thickness of the side member of the medical article and being less than the combined longitudinal lengths of the first and second channel portions, and a base surface for supporting the retainer on the skin of the patient, the first and second channel portions being disposed relative to the base surface so that the longitudinal axis of the retainer defines an incident angle of approximately seven degrees with respect to the base surface.

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.

1. A securement system comprising:
-
a medical article having a generally elongated body including a first body portion and a second body portion, and a side member disposed between the first and second body portions and projecting away from the body; and a retainer having a first channel portion and a second channel portion, the first and second channel portions defining an inner channel surface, 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 inner channel surface contacting the first and second body portions of 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° and
defining an abutment surface, each abutment surface extending generally perpendicular to the longitudinal axis and together defining a slot between the first and second channel portions, the slot receiving the side member of the medical article with at least a portion of the side member projecting in a transverse downward direction below the inner channel surface of the retainer, a distance measured between the abutment surfaces along the longitudinal axis being substantially equal to the thickness of the side member of the medical article and being less than the combined longitudinal lengths of the first and second channel portions, and a base surface for supporting the retainer on the skin of the patient, the first and second channel portions being disposed relative to the base surface so that the longitudinal axis of the retainer defines an incident angle of approximately seven degrees with respect to the base surface. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11)

12. A securement system comprising:
-
a medical article having a generally elongated body including a first body portion and a second body portion, and a side member disposed between the first and second body portions and projecting away from the body; and a retainer having a first channel portion and a second channel portion, the first and second channel portions defining an inner channel surface, 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 inner channel surface contacting the first and second body portions of 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° and
defining an abutment surface, each abutment surface extending generally perpendicular to the longitudinal axis and together defining a slot between the first and second channel portions, the slot receiving the side member of the medical article with at least a portion of the side member projecting in a transverse downward direction below the inner channel surface of the retainer, a distance measured between the abutment surfaces along the longitudinal axis being substantially equal to the thickness of the side member of the medical article and being less than the combined longitudinal lengths of the first and second channel portions, and a base surface for supporting the retainer on the skin of the patient, the base surface being disposed so that a first distance measured in a transverse direction between the base surface and an intersection of the longitudinal axis with the first abutment surface and a second distance measured in the transverse direction between the base surface and an intersection of the longitudinal axis with the second abutment surface defines an incident angle between the longitudinal axis and the base surface of approximately seven degrees. - View Dependent Claims (13, 14, 15, 16, 17)

18. A securement system comprising:
-
a medical article having a generally elongated body including a first body portion and a second body portion, and a side member disposed between the first and second body portions and projecting away from the body; a channel having a first portion, a second portion, and a central axis, the first and second channel portions defining an inner channel surface, the channel portions being disposed about the central axis of the retainer and having a length measured in a direction parallel to the central axis of the retainer, the inner channel surface contacting the first and second body portions of the medical article along at least a substantial portion of the longitudinal lengths of the first and second channel portions, the channel being configured to retain at least a portion of the medical article with the retained portion extending entirely through the channel, the channel having a truncated cross-sectional shape with an opening along the central axis to allow ingress of at least the retained portion of the medical article; at least one slot disposed between the first and second channel portions, the at least one slot extending generally normal to the central axis of the channel and configured to inhibit longitudinal movement of the medical article relative to the retainer, the slot receiving the side member of the medical article with at least a portion of the side member projecting in a transverse downward direction below the inner channel surface of the retainer; and a base surface disposed on the underside of the retainer, wherein the base surface is disposed below the channel, wherein a proximal portion of the base surface is disposed at a first distance spaced from the central axis and a distal portion of the base surface is disposed at a second distance spaced from the central axis that is greater than the first distance so as to define an incident angle of approximately seven degrees, each of the first and second distances being spaced from the central axis so as to support the retained portion of the medical article away from the patient'"'"'s skin when the retainer is placed upon the patient'"'"'s skin. - View Dependent Claims (19, 20, 21, 22)
