Abstract
A support device for preventing an occlusion of a catheter's root region including an extended, flexible member extending from an end of a catheter adapter. The flexible extension is tapered such that additional support is provided to the portions of the root region most susceptible to an occlusion. Additionally, the flexible extension provides shielding to the root region thereby preventing contamination of the same. Finally, the flexible extension provides a marking function whereby the technician may insert the catheter tube until such a point that the flexible extension contacts the patient thereby preventing over insertion of the catheter tube.
Claims20
A support device for a catheter adapter comprising a flexible member extending from a first end of the catheter adapter wherein the flexible member surrounds a root region of a catheter tube thereby protecting the catheter tube from contamination and unintended occlusion.
A method for protecting a root region of a catheter tube from an occlusion including:
- extending a first end of a catheter adapter such that the root region of the catheter tube is covered thereby buttressing the root region in a flexible extension of the catheter adapter;
- configuring the flexible extension to comprise a tapered outer surface such that a first outer diameter of the flexible extension is greater than a second outer diameter of the flexible extension;
- providing an air gap between an inner surface of the flexible extension and an outer surface of the root region of the catheter tube;
- and
- configuring the flexible extension to be generally less flexible than the catheter tube and generally more flexible than the first end of the catheter adapter.
A catheter adapter support system including a flexible means for flexibly supporting a root region of a catheter tube thereby protecting the root region of the catheter from an occlusion.
