Abstract

A securement device for securing a medical article is disclosed. The securement device comprises a base and a first securing portion comprising a strap that is movable between an open position and a closed position and a connector disposed on the base. The strap cooperates with the connector in the closed position to form an enclosure. The strap further comprises a curvilinear segment that projects inwardly into the enclosure in a convex orientation when the strap is in the closed position. Securement systems for securing medical articles and methods of securing at least a portion of a medical article to a patient are also provided.

First claim

What is claimed is:

1. A securement device for securing a medical article, comprising:
a base having a longitudinal axis, a top face, and a bottom face, wherein the longitudinal axis defines a longitudinal direction;
a first securing portion comprising
a strap extending from the top face of the base, wherein the strap has a length, and wherein the strap is moveable between an open position and a closed position; and
a connector disposed on the top face of the base;
wherein the strap cooperates with the connector in the closed position to form an enclosure; and
wherein the strap comprises a curvilinear segment, wherein the curvilinear segment has a length perpendicular to the longitudinal axis, wherein the length of the curvilinear segment projects inwardly into the enclosure in a convex orientation when the strap is in the closed position, wherein the length of the curvilinear segment is about one-third of the length of the strap, and wherein at least a portion of the curvilinear segment deforms or partially deforms such that at least a portion of the curvilinear segment becomes flat or concave with respect to the enclosure when the strap is in the closed position and when the curvilinear segment is compressed against the medical article.

2. The securement device of claim 1 , further comprising a second securing portion comprising
a frame disposed on the top face of the base and defining an interior aperture; and
an entry gap in at least a portion of the frame.

3. The securement device of claim 2 , wherein the entry gap in the frame is smaller than the interior aperture defined by the frame.

4. The securement device of claim 1 , wherein at least a portion of the enclosure of the first securing portion tapers from a wider shape to a narrower shape in the longitudinal direction.

5. The securement device of claim 2 , wherein the first securing portion and the second securing portion are each independently coupled to the base and are spaced a longitudinal distance apart.

6. The securement device of claim 1 , wherein the strap has a proximal end where the strap is joined to the base and a distal end located away from the base when the strap is in the open position; and wherein the strap further comprises a tab located at the distal end.

7. The securement device of claim 6 , wherein the connector comprises a post extending from the top face of the base and a catch mechanism, wherein the catch mechanism engages with the tab when the securement device is in a closed position to form the generally annular enclosure.

8. The securement device of claim 1 , wherein a first flexible joint permanently couples the strap to the base and a second flexible joint permanently couples the strap to the curvilinear segment.

9. The securement device of claim 1 , wherein the curvilinear segment is positioned between the strap and the base and the curvilinear segment is permanently coupled to both the strap and the base.

10. The securement device of claim 1 , wherein the curvilinear segment is positioned in the middle of the strap such that the strap is on either side of the curvilinear segment.

11. The securement device of claim 1 , wherein a flexible joint permanently couples the curvilinear segment to the strap.

12. The securement device of claim 2 , wherein the base, the first securing portion, and the second securing portion are formed as a unitary piece.

13. The securement device claim 1 , further comprising indicia comprising directional cues, such that the indicia provides a visual cue for orienting the securement device on a patient's body.

14. The securement device of claim 1 , wherein the bottom face of the base is secured to a support device, wherein the support device comprises:
a backing layer comprising a first surface and second surface, opposite the first surface, wherein the first surface of the backing layer is liquid water impermeable;
a cushioning element positioned adjacent the second surface of the backing layer;
a base layer comprising a first surface adjacent the cushioning element and a second surface, opposite the first surface of the base layer.

15. The securement device of claim 14 , wherein the second surface of the base layer comprises an adhesive.

16. The securement device of claim 14 , wherein the base layer is entirely contiguous.

17. A securement system for securing a medical article, comprising:
a support device comprising:
a backing layer comprising a first surface and second surface, opposite the first surface, wherein the first surface of the backing layer is liquid water impermeable;
a cushioning element positioned adjacent the second surface of the backing layer;
a base layer comprising a first surface adjacent the cushioning element and a second surface, opposite the first surface of the base layer;
wherein the base layer is entirely contiguous;
wherein the second surface of the base layer comprises an adhesive;
wherein the base layer and backing layer connect entirely around the cushioning element; and

a securement device secured to the first surface of the backing layer of the support device, the securement device comprising:
a base having a longitudinal axis, a top face, and a bottom face, wherein the longitudinal axis defines a longitudinal direction;
a first securing portion comprising:
a strap extending from the top face of the base, wherein the strap has a length, and wherein the strap is moveable between an open position and a closed position; and
a connector disposed on the top face of the base;

wherein the strap cooperates with the connector in the closed position to form an enclosure; and
wherein the strap comprises a curvilinear segment, wherein the curvilinear segment has a length perpendicular to the longitudinal axis, wherein the length of the curvilinear segment projects inwardly into the enclosure in a convex orientation when the strap is in the closed position, wherein the length of the curvilinear segment is about one-third of the length of the strap, and wherein at least a portion of the curvilinear segment deforms or partially deforms such that at least a portion of the curvilinear segment becomes flat or concave with respect to the enclosure when the strap is in the closed position and when the curvilinear segment is compressed against the medical article.

18. The securement system of claim 17 , further comprising indicia comprising directional cues, such that the indicia provides a visual cue for orienting the securement system on a patient's body.
