Catheter anchoring system
First Claim
1. A retainer for securely anchoring a catheter adaptor of the type having an elongated tubular body, a support arm attaching a clip to the adaptor body, and a protuberance disposed on the clip proximal of the support arm, said retainer comprising:
- a pair of opposing longitudinal walls, each wall defining a series of slots with each slot being sized to receive a portion of the support arm of the catheter adaptor which extends through the slot, and to prevent the support arm from moving in a direction parallel to a longitudinal axis of the retainer; and
a central channel extending through said retainer about an axis which is generally parallel to said retainer longitudinal axis, said channel being interposed between said opposing longitudinal walls and having a truncated circular cross-sectional shape which extends through an angle greater than 180°
about said channel axis, such that with the adaptor tubular body positioned within the central channel, said longitudinal walls prevent the adaptor from moving either in transverse or lateral directions which are normal to the longitudinal axis of the retainer.

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 an catheter adaptor in a variety of positions. The adaptor interconnects the catheter and the fluid supply tube. The anchoring system additionally includes an flexible, adhesive base pad which supports a tube clip, as well as the retainer. The retainer desirably slide relative to the base pad to precisely position the retainer relative to the catheter. The retainer advantageously includes an interlocking element which secures the retainer in the manually selected position relative to the catheter.

7. A catheter anchoring system for securely retaining a catheter adaptor interconnecting a catheter and a fluid supply tube, said anchoring system comprising:
-
a base having at least one rail extending along a longitudinal axis of said base; a retainer configured to receive and retain the catheter adaptor, said retainer comprising a groove configured to receive said rail of said base such that said retainer slides over said base, said retainer groove and said rail being configured to prevent said retainer from moving away from said rail in a transverse direction; and an interlocking element preventing said retainer from sliding over said rail with the retainer holding the catheter adaptor. - View Dependent Claims (8)

9. A catheter anchoring system comprising:
-
a catheter adaptor having a tubular body connected to a radially extending support arm supporting a clip which pivots relative to said tubular body; a retainer comprising; a pair of opposing longitudinal walls, each wall defining a series of slots with each slot being sized such that a portion of said support arm of said catheter adaptor extends through the slot, and being sized to prevent said support arm from moving in a direction parallel to a longitudinal axis of said retainer; and a central channel extending through said retainer about an axis which is generally parallel to said retainer longitudinal axis, said channel being interposed between said opposing longitudinal walls and having a truncated circular cross-sectional shape sized to encompass said tubular body through an angle greater than 180°
; anda base pad comprising an adhesive bottom surface which attaches to a patient'"'"'s skin, said base pad supporting said retainer. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method of anchoring a catheter to a patient'"'"'s skin comprising the steps of:
-
positioning a base proximate to an indwelling catheter; sliding a retainer over said base to locate said retainer in a desired position relative to said indwelling catheter; inserting a catheter adaptor into said retainer to prevent said adaptor from moving relative to said retainer; and interlocking said retainer and said base to prevent said catheter adaptor from moving relative to said indwelling catheter. - View Dependent Claims (17, 18, 19, 20)
