Catheter anchoring system
First Claim
1. An anchoring system for securing an indwelling catheter within a body lumen of a patient and for securely interconnecting the indwelling catheter with a tube, said catheter of the type having a proximal end including a lure-lock connector, said anchoring system comprising:
- an adaptor having a generally tubular body with a distal end which is configured to engage the proximal end of the catheter, said distal end including a lure-lock connector which is adapted to engage the corresponding lure-lock connector of the catheter proximal end, said adaptor additionally comprising a radially extending member which projects from an exterior surface of said tubular body in a radial direction at a point distanced from said lure-lock connector of said adaptor distal end; and
a retainer comprising a channel configured to receive said tubular body of said adaptor, said retainer additionally comprising a series of lateral slots sized to receive and to capture said radially extending member of said adaptor with said adaptor positioned within said channel of said retainer so as to prevent said adaptor from sliding within said channel, whereby said series of slots provide multiple positions along said channel where said retainer can receive said radially extending member of said 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 includes a lure-lock fitting to lock onto a hub on the proximal end of the catheter. 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 lateral slots. Each slot is sized to receive and to capture a radically extending member (e.g., an annular collar) of the adaptor to prevent the adaptor from sliding within the channel.

10. A method of anchoring an indwelling catheter/tube interconnection to a patient, comprising the steps of:
-
providing an adaptor having a generally tubular body with a radially extending member and a distal end which is adapted to engage a lure-lock fitting at a proximal end of the catheter; providing an anchor pad with an adhesive back, said anchor pad supporting a retainer configured to securely receive said adaptor, said retainer comprising a central channel and a series of lateral slots, whereby said series of slots provide multiple positions along a longitudinal axis of said retainer where said retainer can receive said radially extending member of said adaptor; adhering said anchor pad to a patient'"'"'s skin proximate to said indwelling catheter; inserting the distal end of the adaptor into the proximal end of the catheter to join the adaptor distal end with the proximal end of the catheter; rotating the lure-lock fitting about the joined ends of the adaptor and catheter to interlock the joined ends; positioning said radially extending member above said series of lateral slots; and inserting said adaptor tubular body into said channel with the radially extending member slipping into one slot of said series of slots.
