Abstract

A securement device for securing a medical article includes two supports extending from a base. Lever arms extend from each of the supports. One or both of the lever arms include a channel portion. The lever arms are pivotable about the ends of the supports to define an open position and a closed position. In the open position, the lever arms extend generally upwardly from the supports. In the closed position, the lever arms extend generally downwardly from the supports, and the channel portion or portions at least partially surround the medical article. As the lever arms move from the open position to the closed position, they exert an outward force on the ends of the supports.

Claims

1. A securement device for securing a medical article, the device comprising:

a base;

first and second supports extending away from the base, each of the first and second supports having a distal end which is spaced apart from the base;

a first lever arm pivotable about the distal end of the first support, the first lever arm comprising a first channel portion;

a second lever arm pivotable about the distal end of the second support, the second lever arm comprising a second channel portion;

the first and second lever arms being movable between an open position, in which the first and second lever arms extend above a line defined by the distal ends of the supports, and a closed position, in which the first and second lever arms extend below the line, the first and second channel portions cooperating to define a receiving area for the medical article when in the open position and cooperating to at least partially surround the medical article when in the closed position.

2. The securement device of claim 1, wherein the supports in the open position extend normal to the base.

3. The securement device of claim 2, wherein the supports in the closed position are angled laterally outward.

4. The securement device of claim 1, wherein the supports in the open position are angled laterally inward.

5. The securement device of claim 1, wherein the distal ends of the first and second supports are spaced apart laterally by a first distance in the open position, the supports passing through an intermediate position as they move towards the closed position, the supports being spaced apart by a second distance in the intermediate position, the second distance being greater than the first distance.

6. The securement device of claim 1, wherein the first and second lever arms are independently movable.

7. The securement device of claim 1, wherein the first and second lever arms are pivotably coupled.

8. The securement device of claim 7, wherein a distal end of the first channel portion is pivotably coupled to a distal end of the second channel portion.

9. The securement device of claim 7, wherein a distal end of the first channel portion is pivotably coupled to a proximal end of the second channel portion.

10. The securement device of claim 7, wherein a distal end of a straight portion of the first lever arm is pivotably coupled to a distal end of a channel portion of the second lever arm.

11. The securement device of claim 7, wherein a distal end of a straight portion of the first lever arm is pivotably coupled to a distal end of a straight portion of the second lever arm.

12. The securement device of claim 1, wherein each of the first and second lever arms comprises a substantially straight portion.

13. The securement device of claim 12, wherein the first and second lever arms pass through an intermediate position as they move from the open position to the closed position, the straight portions of the first and second lever arms being aligned with one another and exerting a lateral force on the distal ends of the first and second supports in the intermediate position.

14. The securement device of claim 13, wherein the distal ends of the first and second supports are elastically deformed in a lateral direction in at least the intermediate position.

15. The securement device of claim 14, wherein the distal ends of the first and second supports are elastically deformed in a lateral direction in the closed position.

16. The securement device of claim 1, wherein the first and second lever arms define a center pivot point in at least the closed position, the center pivot point being lower than the line defined by the distal ends of the first and second supports when the device is in the closed position.

17. The securement device of claim 1, wherein at least one of the first and second channel portions includes an adhesive.

18. The securement device of claim 1, wherein the first and second channel portions are continuous with one another.

19. The securement device of claim 1, further comprising a latch configured to secure the device in the closed position.

20. The securement device of claim 19, wherein the latch is a ratcheting latch.

21. The securement device of claim 19, wherein the latch includes one or more protrusions configured to grip the medical article when the device is in the closed position.

22. A retainer for securing a medical article, the retainer comprising:

a base;

a first support extending from the base;

a second support extending from the base;

a first lever arm coupled to the first support at a first point;

a second lever arm coupled to the second support at a second point; and

at least one channel portion coupled to at least one of the first and second lever arms, at least a portion of the retainer being movable between a first position, in which the first and second lever arms extend generally upward of the first and second points, and a second position, in which the first and second lever arms extend generally downward of the first and second points, the at least one channel portion being configured to at least partially surround the medical article when the retainer is in the second position.

23. The retainer of claim 22, wherein the at least one channel portion is coupled to both the first and second lever arms.

24. The retainer of claim 22, wherein the at least one channel portion is flexible.

25. The retainer of claim 22, wherein the device comprises two channel portions, each channel portion being coupled to one of the first and second lever arms.

26. The retainer of claim 25, wherein the two channel portions are pivotably connected.

27. A securement device for securing a medical article, the device comprising:

a retainer having a first portion and a second portion disposed above a base, the first and second portions being movable in at least a transverse direction with respect to first and second points to define an open position and a closed position, the first and second points being spaced apart from the base, the first and second portions extending generally away from the first and second points when in the open position, the first and second portions extending generally downwardly from the first and second points when in the closed position, the first and second portions causing the first and second points to move laterally outward as the first and second portions move from the open position to the closed position, the first and second portions defining a channel in the closed position, the channel being configured to at least partially surround the medical article in the closed position.

28. A method of securing a medical article to a patient, the method comprising:

providing a retainer comprising a base, first and second supports extending upwardly from the base, a first lever arm pivotable about a distal region of the first support, a second lever arm pivotable about a distal region of the second support, a first channel portion movable with the first lever arm, a second channel portion movable with the second lever arm, the first and second lever arms being movable between an open position, in which the first and second lever arms extend above a line defined by the distal ends of the supports, and a closed position, in which the first and second lever arms extend below the line, the first and second channel portions configured to allow placement of the medical article therebetween in the open position, the first and second channel portions cooperating to at least partially surround the medical article in the closed position;

placing the medical article between at least portions of the first and second channel portions when in an open position; and

applying downward force on at least one of the medical article and the retainer so as to move the lever arms past an intermediate position in which the lever arms are horizontally aligned and into the closed position.
