Abstract

A securement device for retaining medical tubing, catheters, and other medical fixtures proximal a patient'"'"'s skin. The device has a base, at least one channel formed in the base, a flexible strap for overlying the base, and a coupling assembly for coupling the strap to the base. Embodiments for use with Foley catheters include a plurality of channels of differing diameters. Embodiments for use with a peripheral catheter include a single channel for retaining a spin nut. The coupling assembly includes left and right tracks in left and right sides of the base, and left and right rails on an underside of the flexible strap at left and right ends of a body of the strap. The left rail is removably coupled and held within the left track on the base, and the right rail is removably coupled and held within the right track on the base.

Claims

1. A securement device for a spin nut of a peripheral catheter comprising:

a base having front and rear ends and front and rear end walls;

a single channel formed in the base and being arcuate when viewed in vertical cross section, the channel having a primary channel length for receipt of the spin nut and a secondary channel length,

wherein the primary channel length has a first width and the secondary channel length has a second width smaller than the first width,

wherein the channel includes front and rear cut-outs at the front and rear end walls, and the secondary channel length is a combined length of each of the cut-outs,

wherein the cut-outs present front and rear end interior channel faces, such that the spin nut when placed within the primary channel length abuts against the front and rear end interior channel faces to thereby inhibit longitudinal movement of the spin nut relative to the base;

a flexible strap for securing the spin nut in the primary channel length during use of the securement device, the flexible strap having a body and a grasping tab; and

a coupling assembly for removably coupling the flexible strap to the base, said coupling assembly including—

left and right tracks formed in the left and right side walls of the base, and

left and right rails formed on an underside of the flexible strap at generally left and right ends of the body of the strap,

wherein said left rail is removably coupled and held within the left track, and said right rail is removably coupled and held within the right track.

2. The securement device of claim 1, further including an adhesive pad presenting a top side to which a bottom wall of the base is permanently secured and a bottom side having an adhesive surface for removably coupling with a patient'"'"'s skin.

3. The securement device of claim 1,

wherein each of the left and right rails formed on the strap has an elongated body extending from the underside of the strap and longitudinally along the length of the strap, and an elongated bead extending from an end of the elongated body;

and

wherein each of the left and right tracks formed in the base has an interior groove for receipt of the elongated bead of the rail and an exterior bearing for receipt of the elongated body of the rail.

4. The securement device of claim 3,

wherein each of the left and right tracks extend longitudinally through the left and right side walls of the base but do not extend through the entire longitudinal length of the left and right side walls of the base, such that each of the left and right tracks has a closed end and an open end;

and

wherein the exterior bearing of each of the left and right tracks is formed from bottom and top bearing walls, and a diameter of the elongated bead of each rail is greater than a height between the bottom and top bearing walls.

5. The securement device of claim 4, wherein a shape of the left and right rails is not the same, and further wherein a shape of the left and right tracks is not the same.

6. The securement device of claim 4, wherein a shape of the left and right rails is the same, and further wherein a shape of the left and right tracks is the same.

7. A securement device for a catheter comprising:

a base having front and rear ends and front and rear end walls;

a single channel formed in the base and being arcuate when viewed in vertical cross section;

a flexible strap for securing the catheter in the channel during use of the securement device, the flexible strap having a body and a grasping tab; and

a coupling assembly for removably coupling the flexible strap to the base, said coupling assembly including—

left and right tracks formed in the left and right side walls of the base, and

left and right rails formed on an underside of the flexible strap at generally left and right ends of the body of the strap,

wherein said left rail is removably coupled and held within the left track, and said right rail is removably coupled and held within the right track.

8. The securement device of claim 7, further including an adhesive pad presenting a top side to which the bottom wall of the base is permanently secured and a bottom side having an adhesive surface for removably coupling with a patient'"'"'s skin.

9. The securement device of claim 7,

wherein each of the left and right rails formed on the strap has an elongated body extending from the underside of the strap and longitudinally along the length of the strap, and an elongated bead extending from an end of the elongated body;

and

wherein each of the left and right tracks formed in the base has an interior groove for receipt of the elongated bead of the rail and an exterior bearing for receipt of the elongated body of the rail.

10. The securement device of claim 9,

wherein each of the left and right tracks extend longitudinally through the left and right side walls of the base but do not extend through the entire longitudinal length of the left and right side walls of the base, such that each of the left and right tracks has a closed end and an open end;

and

wherein the exterior bearing of each of the left and right tracks is formed from bottom and top bearing walls, and a diameter of the elongated bead of each rail is greater than a height between the bottom and top bearing walls.
