Catheter anchoring system
DCFirst Claim
1. A catheterization system comprising:
- a catheter including an adaptor with a radially extending member that projects from said adaptor; and
a retainer including first and second channel portions which extend about a longitudinal axis, each channel portion generally having a truncated cross-sectional shape with an opening along said longitudinal axis, and the cross section of at least one of the first and second channel portions tapering along its length, each channel portion having an upper opening of a width that is smaller than a diameter size of the adaptor and each channel portion being sized to surround at least a portion of the adaptor through an arc of greater than 180°
about said longitudinal axis and at least one of the channel portions having walls which deflect outwardly as the adaptor is inserted through the opening and move inwardly toward their undeflected position once the adaptor is within the channel portion, and at least one lateral slot that extends generally perpendicular to said longitudinal axis and lies between said first and second channel portions, said slot having a longitudinal length so dimensioned to substantially equal the thickness of the radially extending member of said adaptor and to be less than the combined longitudinal lengths of said first and second channel portions to provide lateral stability of the adaptor within the retainer with the radially extending member positioned within said lateral slot.

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 takes the form of a conical-shaped fitting permanently attached to the collar and includes a radially extending member that projects from 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 lateral slots. Each slot is sized to receive and to capture the radically extending member (e.g., an annular collar) of the adaptor to prevent the adaptor from sliding within the channel.

about said longitudinal axis and at least one of the channel portions having walls which deflect outwardly as the adaptor is inserted through the opening and move inwardly toward their undeflected position once the adaptor is within the channel portion, and at least one lateral slot that extends generally perpendicular to said longitudinal axis and lies between said first and second channel portions, said slot having a longitudinal length so dimensioned to substantially equal the thickness of the radially extending member of said adaptor and to be less than the combined longitudinal lengths of said first and second channel portions to provide lateral stability of the adaptor within the retainer with the radially extending member positioned within said lateral slot.- View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15)

16. An anchoring system for use with a catheter having an adaptor with a radially extending member projecting therefrom, said anchoring system comprising:
-
a retainer including first and second channel portions which extend about a longitudinal axis, each channel portion generally having a truncated circular cross-sectional shape with an opening along said longitudinal axis, each channel portion being sized to surround at least a portion of the adaptor through an arc of greater than 180°
about said longitudinal axis wherein the cross section of at least one of the first and second channel portions tapers along its length to form a truncated conical shape and said retainer also including at least two lateral slots which extend generally perpendicular to said longitudinal axis and lie between said first and second channel portions, each of said slots having a longitudinal length so dimensioned to substantially equal the thickness of the radially extending member of said adaptor and to be less than the combined longitudinal lengths of said first and second channel portions to provide lateral stability of the adaptor within the retainer with the radially extending member positioned within said lateral slot, each lateral slot being so dimensioned to receive the radially extending member of the catheter adaptor to prevent the catheter from moving in a longitudinal direction, said lateral slots being arranged next to each other along the longitudinal axis of the retainer so as to provide multiple positions in the longitudinal direction in which to insert said radially extending member; and
a flexible anchor pad having an adhesive bottom surface and a top surface on which said retainer is mounted, said retainer being positioned on said top surface in a position exposing the openings of said channel portions. - View Dependent Claims (17, 18, 19, 20, 21)

22. An anchoring system for use with a catheter having an adaptor with a radially extending member projecting therefrom, said anchoring system comprising:
a retainer including first and second channel portions which extend about a longitudinal axis, each channel portion being configured to receive a corresponding portion of the catheter adaptor, and a plurality of lateral slots, each lateral slot being dimensioned so as to receive the radially extending member of the catheter adaptor to prevent the catheter from moving in a longitudinal direction, said lateral slots being arranged next to each other along the longitudinal axis so as to provide multiple positions in the longitudinal direction in which to insert the radially extending member. - View Dependent Claims (23, 24, 25, 26, 27)
