Catheter anchoring system

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.

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.
