摘要

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 takes the form of a conical-shaped fitting permanently attached to the collar and includes a recess which extends around the circumference of the adaptor. The anchoring system additionally includes a flexible, adhesive anchor pad which 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 projections. Each projection is sized to be received by a recess of the adaptor to prevent the adaptor from sliding within the channel.
