Abstract

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.

An anchoring device as in claim 4, wherein each channel includes a chamfered section leading into said narrowed upper opening.
Claim 7
Dependent Claim 21 words
An anchoring device as in claim 1, wherein the spacing between adjacent dividers varies in a direction away from said base.
Claim 8
Dependent Claim 33 words
An anchoring device as in claim 6, wherein the spacing between adjacent distal ends of said dividers is closer than the spacing between said adjacent dividers at a point proximal to said base.
Claim 9
Dependent Claim 26 words
An anchoring device as in claim 1, wherein said flexible pad has a laminate structure formed by a cellulose foam layer and said adhesive bottom surface.
Claim 10
Dependent Claim 30 words
An anchoring device as in claim 1, wherein each channel includes an axis, and the channels are arranged such that at least two of the channels have generally parallel axes.
Claim 11
Dependent Claim 173 words
An anchoring device for securing an indwelling catheter within a body lumen of a patient proximal to an insertion site of the catheter into the body lumen, said anchoring device comprising: a clip comprising a plurality of upwardly extending dividers, at least two of the dividers being adjacent posts with flared outer ends, the dividers being spaced apart from one another to define at least three channels for receiving said catheter, said at least two adjacent posts defining at least a portion of each of said at least three channels, said channels being arranged adjacent to each other and in a non-overlapping manner, an opening of each channel near the flared outer ends of the posts being sized to be smaller than a diameter of the catheter to be retained by the anchoring device, whereby the catheter has a generally serpentine-like shape when positioned within said at least three adjacent channels; and a flexible anchor pad comprising an adhesive bottom surface that attaches to the patient's skin, said anchor pad supporting said clip.
Claim 12
Dependent Claim 173 words
An anchoring device for securing an indwelling catheter within a body lumen of a patient proximal to an insertion site of the catheter into the body lumen, said anchoring device comprising: a clip comprising a plurality of upwardly extending dividers, at least two of the dividers being adjacent posts with flared outer ends, the dividers being spaced apart from one another to define at least three channels for receiving said catheter, said at least two adjacent posts defining at least a portion of each of said at least three channels, said channels being arranged adjacent to each other and in a non-overlapping manner, an opening of each channel near the flared outer ends of the posts being sized to be smaller than a diameter of the catheter to be retained by the anchoring device, whereby the catheter has a generally serpentine-like shape when positioned within said at least three adjacent channels; and a flexible anchor pad comprising an adhesive bottom surface that attaches to the patient's skin, said anchor pad supporting said clip.
