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.

Claims

1. A medical line securement system comprising:

a medical article;

two anchor pads, each including a lower adhesive surface configured to attach to an epidermal layer of a patient; and

a retainer comprising,

a body member having a channel formed therethrough about a channel axis, 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 at least ingress of the portion of the medical article into the channel,

at least one abutment extending generally normal to the channel axis and configured to inhibit longitudinal movement of the medical article, and

two supports disposed on the underside of the retainer and to both sides of the access opening opposite the channel axis, each support being attached to one of the two anchor pads.

2. A medical line securement system as in claim 1 wherein the channel further comprises an inner surface, at least a portion of said inner surface coated with an adhesive and configured to contact the portion of the medical article.

3. A medical line securement system as in claim 2 wherein the portion of said inner surface coated with the adhesive is located opposite the longitudinal access opening.

4. 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.

5. 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.

6. 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.

7. 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.

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

9. A medical line securement system as in claim 8, wherein an outer surface of the medical article has a second tapering shape.

10. A medical line securement system as in claim 9, 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.

11. A medical line securement system as in claim 1, wherein the two supports are mounting wings coupled to the body member and configured to attach to the two anchor pads.

12. A retainer configured for use with a medical article, the retainer comprising:

a body member comprising,

a channel formed through the body member, the channel having an inner surface, at least a portion of said inner surface coated with an adhesive and configured to contact at least a portion of the medical article, and having a longitudinal access opening disposed opposite the portion of said inner surface coated with the adhesive on an underside of the body member to allow at least ingress of the portion of the medical article into the channel,

at least one abutment extending generally normal to an axis of the inverted channel and configured to inhibit longitudinal movement of the medical article in at least one direction, and

at least one support disposed on the underside of the retainer and to a side of the access opening opposite the channel axis.

13. A retainer as in claim 12, wherein the at least one abutment is disposed at a distal end of the channel.

14. A retainer as in claim 12, wherein the at least one abutment is configured to abut against a contact surface on the medical article.

15. A retainer as in claim 14, wherein the contact surface comprises a surface of a radially extending member.

16. 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 having an inner surface, at least a portion of said inner surface coated with an adhesive and configured to contact 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,

an abutment extending generally normal to an axis of the channel at a distal end of the channel and configured to inhibit longitudinal movement of the medical article in at least one direction,

at least one support surface disposed on the underside of the retainer and to a side of the access opening opposite the channel axis.

17. A medical line securement system as in claim 16, wherein the medical article is a catheter hub.

18. A medical line securement system as in claim 16, wherein the medical article is a connector fitting.

19. A medical line securement system as in claim 16, wherein the medical article comprises at least one contact surface which is configured to abut against the abutment to arrest movement of the medical article in a proximal direction.

20. A retainer configured for use with a medical article comprising a spin nut, the retainer comprising:

a body member comprising,

a channel formed through the body member, the channel having an inner surface, at least a portion of said inner surface coated with an adhesive and configured to contact at least a portion of the medical article lying proximal from the spin nut, and having a longitudinal access opening disposed opposite the portion of said inner surface coated with the adhesive on an underside of the body member to allow at least ingress of the portion of the medical article into the channel,

an abutment extending generally normal to an axis of the channel at a distal end surface of the channel, and configured to contact the spin nut and inhibit longitudinal movement of the medical article in a proximal direction, and

two supports disposed on an underside of the retainer and to opposite sides of the access opening opposite the channel axis.
