Catheter anchoring system
First Claim
1. A catheterization system comprising:
- a catheter adaptor including at least one recess; and
a retainer including a channel that extends through the retainer about a longitudinal axis, the channel configured such that at least a portion of the channel has a truncated cross-sectional shape with an opening along the longitudinal axis and is sized to surround at least a portion of the adaptor through an arc of greater than 180°
about the longitudinal axis, and at least one projection that projects into the channel in a direction generally normal to the longitudinal axis, the projection having a longitudinal length so dimensioned to substantially equal the longitudinal length of the recess of the adaptor.

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.

19. An anchoring system for use with a catheter having an adaptor with a recess, the anchoring system comprising:
-
a retainer including a channel that extends through the retainer about a longitudinal axis, the channel configured such that at least a portion of the channel has a truncated cross-sectional shape with an opening along the longitudinal axis and is sized to surround at least a portion of the adaptor through an arc of greater than 180°
about the longitudinal axis, and at least one projection that projects into the channel in a direction generally normal to the longitudinal axis, the projection having a longitudinal length so dimensioned to substantially equal a longitudinal length of the recess of the adaptor; and
a flexible anchor pad having an adhesive bottom surface and a top surface on which the retainer is mounted. - View Dependent Claims (20, 21, 22, 23, 24, 25, 27)

26. A method of anchoring an indwelling catheter/tube interconnection to a patient, comprising the steps of:
-
providing an adaptor having a recess, the adaptor being attached to a catheter;
providing a retainer including a channel portions which extend about a longitudinal axis and at least one projection which projects into the channel generally toward the longitudinal axis;
providing an anchor pad with an adhesive back, the anchor pad supporting the retainer;
adhering the anchor pad to a patient'"'"'s skin proximate to the indwelling catheter;
positioning the recess of the adaptor above the projection of the retainer; and
pressing the adaptor into the retainer so that the adaptor is placed within the channel with the recess receiving the projection so as to inhibit movement of the adaptor in a longitudinal direction relative to the retainer.

- 28. A securement system for an elongated medical article comprising an adaptor including a body defined about a longitudinal axis, the body having at least one recess thereon, and a retainer including a first side and a second side that together define a space of sufficient size to receive a portion of the adaptor, the retainer receiving at least a portion of the adaptor within the space in a snap-fit manner, and a projection extending in a direction generally normal to the longitudinal axis of the adaptor, the projection having a longitudinal length so dimensioned to substantially equal a longitudinal length of the recess of the adaptor so as to cooperate with the recess of the adaptor in a manner substantially inhibiting axial motion of the adaptor within the retainer.
