Abstract

In one aspect, a catheter securement device comprises a body portion having an upper surface and a lower surface, the body portion having a pocket that comprises a substantially tubular channel, the channel being open at the upper surface, the pocket further including a port cavity in communication with the channel. The securement device further comprises a strap portion movable between a fully closed position and a range of open positions. The strap portion at least partially covers the pocket when in a closed position thereby closing the channel at the upper surface. The strap portion allows access to the channel when in an open position.

First claim

What is claimed is:

1. A catheter securement assembly comprising:
a securement device including:
a body portion having an upper surface and a lower surface, the body portion having a pocket that comprises a substantially tubular channel, the channel being open at the upper surface, the body portion including a protrusion that extends from an external surface of the body portion; and
a strap portion movable between a fully closed position and a range of open positions, the strap portion at least partially covering the pocket when in a closed position thereby closing the channel at the upper surface, the strap portion allowing access to the channel when in an open position, wherein the strap portion includes an opening extending therethrough, the opening sized to receive and engage the protrusion therein to secure the strap portion to the body portion in the fully closed position; and

a support structure connected to the lower surface of the body portion, the support structure including:
a retainer having an opening extending therethrough; and
a pivot member extending through the opening of the retainer to couple the retainer and the body portion.

2. The catheter securement assembly of claim 1 wherein the body portion includes opposing side surfaces and wherein the channel is a single tubular channel that extends from one side surface to the other side surface.

3. The catheter securement assembly of claim 1 wherein the retainer is generally rectangular, the support structure further comprising:
a support material connected to the lower surface of the body portion of the securement device, the support material having a surface area greater than a surface area of the lower surface of the body portion, the support material having a support material upper side that extends adjacent to the pivot member.

4. The catheter securement assembly of claim 1 , wherein the support structure further comprises:
a support material;
wherein the retainer is disposed at the lower surface of the body portion of the securement device; and

wherein the pivot member permits pivoting of the body portion relative to the support material.

5. The catheter securement assembly of claim 1 , the channel having an oblong cross-section.

6. The catheter securement assembly of claim 1 wherein the opening is larger than a cross section of the protrusion such that at least a portion of the opening is spaced from the protrusion when the strap portion is in the fully closed position.

7. The catheter securement assembly of claim 1 wherein a material of the strap portion entirely surrounds the opening.

8. The catheter securement assembly of claim 1 wherein the protrusion includes an enlarged portion and a lip that extends from the enlarged portion.

9. The catheter securement assembly of claim 8 wherein the lip extends from the enlarged portion in a direction generally corresponding to a closing direction of the strap portion.

10. A catheter securement device comprising:
a body portion having an upper surface and a lower surface, the body portion having a pocket that comprises a substantially tubular channel, the channel being open at the upper surface, the pocket further including a port cavity in communication with the channel;
a strap portion movable between a fully closed position and a range of open positions, the strap portion at least partially covering the pocket when in a closed position thereby closing the channel at the upper surface, the strap portion allowing access to the channel when in an open position; and
a support structure connected to the lower surface of the body portion, the support structure including:
a support material connected to the lower surface of the body portion of the securement device, the support material having a surface area greater than a surface area of the lower surface of the body portion, the support material having a support material upper side and a support material lower side; and
a retainer, the retainer having a first retainer portion disposed at the support material lower side and a second retainer portion that protrudes through the support material and that engages the securement device, the securement device and the retainer each being composed of silicone material having a Shore A durometer rating in the range of 40-80.

11. A catheter securement system comprising:
a catheter tube assembly that includes a tube structure and a fitting that includes a fluid outlet;
a securement device assembly comprising:
a securement device having:
a body portion with an upper surface and a lower surface, the body portion having a pocket sized to receive at least a portion of the fitting within the pocket, the pocket comprising a substantially tubular channel; and

a strap portion movable between a fully closed position and a range of open positions, the strap portion at least partially covering the pocket when in a closed position thereby closing the channel at the upper surface, the strap portion allowing access to the channel when in an open position, the strap portion including an opening extending therethrough, the opening at least partially aligned with the fluid outlet when the strap portion is in the closed position to permit fluidic communication from within the fitting through the opening of the strap.

12. The system of claim 11 wherein the body portion includes opposing side surfaces and wherein the channel is a single tubular channel that extends from one side surface to the other side surface.

13. The system of claim 11 wherein the fluid outlet is a luer port that extends at least partially through the opening of the strap portion when the strap portion is in the closed position.

14. The system of claim 11 , the channel having an oblong cross-section.

15. The system of claim 11 wherein the fluid outlet is exposed through the opening when the strap portion is in the closed position.

16. The system of claim 11 wherein the body portion includes a protrusion that extends from an external surface of the body portion, and wherein the opening of the strap portion surrounds at least a portion of the protrusion and at least a portion of the fluid outlet when the strap portion is in the closed position.

17. The system of claim 11 wherein the fluid outlet is a vent that is at least partially aligned with the opening of the strap portion when the strap portion is in the closed position.

18. The system of claim 11 further comprising a support structure, the support structure comprising:
a support material;
a retainer disposed at the lower surface of the body portion and having an opening extending therethrough; and
a pivot member extending through the opening of the retainer to pivotally connect the retainer to the body portion.

19. The system of claim 18 wherein the pivot member includes an upper pivot member and a lower pivot member that is secured to the upper pivot member.

20. The system of claim 18 wherein the pivot member includes an upper pivot member that extends at least partially within the tubular channel and a lower pivot member that extends between the retainer and the support material.

21. The system of claim 18 wherein the pivot member includes an upper pivot member having an upper planar portion that extends within the tubular channel and a lower pivot member having a lower planar portion that extends between the retainer and the support material.

22. A method comprising:
providing a catheter securement system that comprises a
