Abstract

A catheter securement device holds a medical article such as a catheter hub or a connector fitting in position upon the body of a patient and at least inhibits longitudinal movement of the medical article. The securement device includes a retainer and at least one anchor pad. The retainer forms a central channel into which at least a portion of the medical article is inserted. The retainer includes at least one abutment that can abut against a contact point or surface on the medical article. The abutment, in conjunction with a second abutment and/or a tapering shape of the central channel, inhibits motion of the medical article in proximal and distal directions through the central channel. For this purpose, the abutment surface(s) can lie either within or outside the channel.

2. A medical line securement system as in claim 1 wherein the medical article comprises at least one contact surface which is configured to abut against the at least one abutment to arrest movement of the medical article in at least one direction.

3. A medical line securement system as in claim 1 wherein the at least one abutment is located between proximal and distal ends of the body member along the axis of the channel.

4. A medical line securement system as in claim 1 wherein the at least one abutment is a surface on a proximal end of the body member along the axis of the channel.

5. A medical line securement system as in claim 1 wherein the at least one abutment is located on a distal end of the body member along the axis of the channel.

6. A medical line securement system as in claim 2 wherein the at least one contact surface comprises a surface of a radially extending member.

7. A medical line securement system as in claim 6, wherein the radially extending member extends about the circumference of the medical article.

8. A medical line securement system as in claim 6, wherein the radially extending member extends substantially parallel to the medical article.

9. A medical line securement system as in claim 6, wherein the retainer comprises two abutments disposed between the proximal and distal ends of the medical article to form a slot therebetween, and wherein the slot receives the radially extending member when the medical article is inserted into the channel.

10. A medical line securement system as in claim 1 wherein the medical article is a catheter hub.

11. A medical line securement system as in claim 1 wherein the medical article is a connector fitting.

12. A medical line securement system as in claim 1 wherein the medical article comprises two contact surfaces, and wherein the body member of the retainer is sized to fit between the two contact surfaces.

13. A medical line securement system as in claim 1 wherein the medical article comprises two contact surfaces and the body member of the retainer comprises two abutments, and wherein the two contact surfaces abut against the two abutments.

14. A medical line securement system as in claim 1, wherein the channel has an arc length of greater than 180 degrees.

15. A medical line securement system as in claim 1, wherein the channel has a first tapering shape.

16. A medical line securement system as in claim 15, wherein an outer surface of the medical article has a second tapering shape.

17. A medical line securement system as in claim 16, wherein the first tapering shape and the second tapering shape cooperate together when the medical article is inserted into the channel to limit longitudinal movement of the medical article in a first direction.

18. A medical line securement system as in claim 17 wherein the medical article comprises a contact surface which abuts against the at least one abutment to limit longitudinal movement of the medical article in a second direction.

19. A medical line securement system as in claim 1, wherein the retainer comprises a retention surface which is configured to inhibit transverse motion of the medical article.

20. A medical line securement system as in claim 19, wherein the retention surface is located in the channel.

21. A medical line securement system as in claim 20 wherein the retention surface provides a snap-fit securement with the portion of the medical article.

22. A medical line securement system as in claim 20, wherein the retention surface flexes when the medical article is inserted into the channel.

23. A medical line securement system as in claim 22, wherein the retention surface is a movable wall.

24. A medical line securement system as in claim 20, wherein the channel has a radius of R and wherein the retention surface is located at a distance of greater than R from the axis of the channel.

25. A medical line securement system as in claim 1, wherein the at least one support is a first mounting wing coupled to the body member and configured to attach to the at least one anchor pad.

26. A medical line securement system as in claim 1, wherein the abutment comprises an adhesive, the adhesive adhering to the medical article when the medical article is inserted into the retainer.

27. A medical line securement system as in claim 1, wherein a portion of the body member is transparent to facilitate alignment and ingress when inserting the medical article into the channel.

28. A medical line securement system as in claim 9, further comprising a stop member which extends into a portion of the slot such that when the medical article is inserted into the channel and rotated in a first direction around the axis of the channel, the radially extending member slides within the slot until the radially extending member contacts the stop member.

29. A medical line securement system as in claim 1, wherein the abutment comprises a wall of a slot.

30. A medical line securement system as in claim 1, wherein the abutment comprises a ridge.

31. A medical line securement system as in claim 1, wherein the abutment comprises a protuberance.

32. A medical line securement system comprising:

a medical article having a connector;

a retainer comprising,

a body member having a channel formed therethrough, the channel being configured to retain at least a portion of the medical article and having a longitudinal access opening disposed on an underside of the body member to allow ingress of the portion of the medical article into the channel,
