Abstract

A securement device configured to secure an external portion of a medical device to the skin surface of a patient after an internal portion of the device has been placed in the patient is disclosed. The securement device includes a retainer that is employed to securely retain the external portion of the medical device in place. The retainer is attached to a base, such as an adhesive pad that adhesively attaches to the skin surface. In one embodiment, therefore, a retainer comprises a body defining a channel configured to receive therein a portion of the medical device, and at least one foot extending from the body that is configured to stabilize the retainer with respect to a skin surface. The retainer body further includes a nose that is configured to deflect a portion of the external portion of the medical device toward the skin insertion site.

7. The retainer as defined in claim 3, wherein the channel is configured to receive a portion of at least one of a hub and a strain relief of the catheter assembly.

8. The retainer as defined in claim 1, wherein the body further defines a notch configured to receive therein a portion of a skin-placed dressing.

9. The retainer as defined in claim 8, wherein the body of the retainer defining the notch is configured to impart a compressive force on the skin-placed dressing when the portion of the skin-placed dressing is received in the notch.

10. The retainer as defined in claim 8, wherein the skin-placed dressing is an antimicrobial disk.

11. The retainer as defined in claim 10, wherein the retainer includes two feet and wherein the feet are shaped to border an outer perimeter of the antimicrobial disk.

12. The retainer as defined in claim 1, wherein the at least one foot includes a living hinge configured to enable the at least one foot to bend about the skin surface,

13. The retainer as defined in claim 1, wherein the retainer comprises part of a securement device, the securement device including at least one adhesive anchor pad configured to anchor the retainer to the skin surface.

14. A securement device for retaining an external portion of a catheter assembly after insertion of an internal portion of the catheter assembly into a body of a patient via a skin insertion site, comprising:

a retainer comprising;

a body defining a channel configured to receive therein a portion of the external portion of the catheter assembly, the body further including a distal nose portion configured to deflect a distal portion of the external portion of the catheter assembly toward the skin insertion site; and

at least one foot extending from the body configured to stabilize the retainer with respect to a skin surface of the patient; and

at least one adhesive anchor pad permanently attached to the retainer and configured to anchor the catheter retainer system to the skin surface of the patient.

15. The securement device as defined in claim 14, wherein the at least one foot includes first and second feet, and wherein the at least one adhesive anchor pad includes first and second adhesive pads attached to the respective first and second feet.

16. The securement device as defined in claim 14, wherein the securement device is configured for placement on an arm of the patient and is configured to retain a peripheral IV catheter.

17. The securement device as defined in claim 14, wherein the channel is configured to receive portions of at least one of a hub and a strain relief of the catheter assembly in a snap-fit arrangement.

18. The securement device as defined in claim 17, wherein the channel includes first and second pockets configured to receive first and second nubs of the strain relief of the catheter assembly.

19. The securement device as defined in claim 18, wherein the nose is configured to deflect at least one of the strain relief and a catheter tube of the catheter assembly with respect to a relatively more proximal portion of the catheter assembly.

20. The securement device as defined in claim 14, wherein the body further defines a notch configured to receive therein a portion of a skin-placed dressing.

21. The securement device as defined in claim 20, wherein the body of the retainer defining the notch is configured to impart a compressive force on the skin-placed dressing when the portion of the skin-placed dressing is received in the notch.

22. The retainer as defined in claim 20, wherein the skin-placed dressing is an antimicrobial disk.

23. The securement device as defined in claim 22, wherein the at least one anchor pad is shaped to border an outer perimeter of the antimicrobial disk when the portion of the antimicrobial disk is received in the notch.

24. The securement device as defined in claim 14, wherein the body of the retainer includes a removable cap that enables a portion of the catheter assembly to be received in the channel.

25. The securement device as defined in claim 14, wherein the retainer includes first and second feet that extend proximally from the body of the retainer.

26. A securement device for retaining an external portion of a catheter assembly after insertion of an internal portion of the catheter assembly into a body of a patient via a skin insertion site, comprising:

a body defining a channel configured to receive therein portions of a hub and a strain relief of the catheter assembly, the body further including a nose configured to deflect the strain relief of the catheter assembly toward the skin insertion site;

a first foot and a second foot extending from the body;

a notch defined by the body and configured to enable a skin-placed dressing to be interposed between the body and the skin surface of the patient proximate the skin insertion site; and
