Catheter securement device

1. A securement device for a catheter, said securement device comprising:

a base configured for attachment to a patient's skin over a catheter insertion site, said base comprising a top surface, a bottom surface, and a central opening configured to accommodate the catheter inserted therethrough from the catheter insertion site;

a cover member attached to said base over said opening, said cover member movable from an open position to a closed position over the catheter insertion site, said cover member configured to secure the catheter in place;

an annular lip configured around at least a portion of said opening on said bottom surface of said base, wherein said lip is configured to reduce leakage from the catheter insertion site when the securement device is secured to the patient's skin; and

a housing mounted on said base and surrounding said opening, said housing comprising an outer-most annular perimeter wall and an annular top wall extending generally perpendicular from the annular perimeter wall towards the opening to define an annular interior space within the annular perimeter directly below the annular top wall and above the base, the annular interior space configured to receive the catheter therein, wherein said housing is configured such that the catheter coils within said annular interior space, the cover member positioned within the annular perimeter wall of the housing and spaced apart from the annular interior space in a radial direction.

2. The securement device of claim 1 , wherein said cover member is hinged to said base at a hinge line.

3. The securement device of claim 2 , further comprising a latch device, wherein said cover member latches to said base via said latch device when said cover member is in the closed position.

4. The securement device of claim 1 , wherein said cover member further comprises a groove configured to accommodate the catheter, wherein said groove is configured to frictionally engage the catheter without compromising a lumen within the catheter.

5. The securement device of claim 1 , wherein said lip surrounds said opening such that when said base is secured to the patient's skin, said lip forces the patient's skin around the catheter to form a seal and reduce leakage from the catheter insertion site.

6. The securement device of claim 5 , wherein said lip comprises an arcuate cross-sectional shape.

7. The securement device of claim 1 , wherein said housing further comprises one or more slots configured to receive the catheter.

8. The securement device of claim 7 , wherein said housing further comprises at least three slots, wherein each of said at least three slots is spaced approximately ninety degrees apart from another one of said at least three slots.

9. The securement device of claim 1 , wherein said housing is integral with said base.

10. The securement device of claim 1 , further comprising an attachment pad connected to a lower surface of said base, said attachment pad having an adhesive lower surface for attachment to the patient's skin.

11. A securement device assembly, comprising:

a catheter having a proximal end, a distal end, and walls defining a lumen;

a securement device, comprising:

a base configured for attachment to a patient's skin over a catheter insertion site, said base comprising top and bottom surfaces, an opening configured to accommodate the catheter inserted therethrough from the catheter insertion site;

a cover member configured with said base over said opening, said cover member movable from an open position to a closed position over the catheter insertion site, said cover member configured to secure the catheter;

a lip configured around at least a portion of said opening on said bottom surface of said base, wherein said lip is configured to reduce leakage from the catheter insertion site when the securement device is secured to the patient's skin; and

a housing mounted on said base and surrounding said opening, said housing comprising an outer-most annular perimeter wall and an annular top wall extending generally perpendicular from the annular perimeter wall towards the opening to define an annular interior space within the annular perimeter wall directly below the annular top wall and above the base, the annular interior space configured to receive the catheter therein, wherein said housing is configured such that the catheter coils within said annular interior space, the cover member positioned within the annular perimeter wall of the housing and spaced apart from the annular interior space in a radial direction.

12. The securement device assembly of claim 11 , wherein said cover member is hinged to said base at a hinge line.

13. The securement device assembly of claim 11 , further comprising a latch device, wherein said cover member latches to said base via said latch device when said cover member is in the closed position.

14. The securement device assembly of claim 11 , wherein said cover member further comprises a groove configured to accommodate the catheter, wherein said groove is configured to frictionally engage the catheter without compromising a lumen within the catheter.

15. The securement device assembly of claim 11 , wherein said lip surrounds said opening such that when said base is secured to the patient's skin, said lip forces the patient's skin around the catheter to form a seal and reduce leakage from the catheter insertion site.

16. The securement device assembly of claim 15 , wherein said lip comprises an arcuate cross-sectional shape.

17. The securement device assembly of claim 11 , further comprising an attachment pad connected to a lower surface of said base, said attachment pad having an adhesive lower surface for attachment to the patient's skin.
