Abstract

A securement device includes a retainer having at least one retention member extending into a channel of the retainer. The retention member is coupled to the retainer and includes a distal end. The distal end is movable relative to the retainer. The retention member can extend from the body and/or supports of the retainer on opposite sides of the channel axis. In some embodiments, a first set of retention members extends from a first support and a second set of retention members extends from the other support. The first set and the second set of retention members can be staggered laterally along the channel axis such that the lateral sides of the retainer are asymmetric which allow the same retainer to secure medical article having different shapes and sizes. The retainer may further include one or more abutment features or pills configured to contact the medical article.

Claims

1. A retainer for securing a medical article, 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 at least ingress of a portion of the medical article into the channel;

first and second supports disposed on the underside of the retainer and located on opposite sides of the channel; and

at least one retention member pivotably coupled to the body member or the first and second supports and having a distal end, at least a portion of the distal end being disposed in the channel so as to contact an outer surface of the portion of the medical article when the medical article is secured within the retainer.

2. The retainer of claim 1, wherein the distal end comprises a retention surface configured to engage a contact surface of the medical article.

3. The retainer of claim 2, wherein at least a portion of the retention surface is contoured so as to match a contact surface of the medical article.

4. The retainer of claim 2, wherein the retention surface includes at least an upper facing portion.

5. The retainer of claim 4, wherein the retention surface includes at least a lateral facing portion.

6. The retainer of claim 1, wherein the at least one retention member comprises an abutment surface extending generally normal to a central axis of the channel, the abutment surface being disposed so as to inhibit longitudinal translation of the medical article relative to the retainer.

7. The retainer of claim 1, wherein the at least one retention member comprises a first retention member and a second retention member, the first retention member extending from the first support and the second retention member extending from the second support.

8. The retainer of claim 7, wherein the first retention member and the second retention member are staggered laterally along a central axis of the channel.

9. The retainer of claim 7, wherein a length of the first retention member is different than a length of the second retention member.

10. The retainer of claim 7, wherein a distal end of the first retention member is movable relative to a distal end of the second retention member.

11. The retainer of claim 1, wherein the at least one retention member is movable between at least a first position and a second position, the at least one retention member being biased toward the first position.

12. The retainer of claim 1, wherein the at least one retention member is coupled to one of the first and second supports via a living hinge.

13. An apparatus for retaining a portion of a medical article, the apparatus comprising:

a body having a channel extending therethrough about a longitudinal axis, the channel being shaped to retain at least a portion of the medical article;

a first support and a second support located on the underside of the body and on opposite sides of the channel;

a plurality of retention members extending from the first and second supports and into the channel, the plurality of retention members being spaced along the longitudinal axis, each of the retention members having a secured end and an unsecured end, the unsecured end being movable relative to the secured end; and

a pair of anchors comprising lower adhesive surfaces configured to be secured to the skin of a patient, the anchors supporting the retainer.

14. The apparatus of claim 13, wherein the body comprises a proximal portion extending between the first and second supports and over the channel and a distal portion extending between the first and second supports and over the channel.

15. The apparatus of claim 13, wherein the plurality of retention members comprises a first set of retention members extending from the first support.

16. The apparatus of claim 15, wherein the plurality of retention members comprises a second set of retention members extending from the second support.

17. The apparatus of claim 16, wherein the first set of retention members and the second set of retention members are staggered laterally along the longitudinal axis such that the retainer is asymmetric across the longitudinal axis.

18. The apparatus of claim 14 further comprising a finger extending downward from the proximal portion into the channel, the finger being compressible in an upward direction.

19. The apparatus of claim 14, wherein the proximal portion and the distal portion at least partially define an opening therebetween, the opening being sized to receive at least a portion of an outwardly extending member of the medical article.

20. The apparatus of claim 14, wherein at least one of the proximal portion and the distal portion comprises at least one abutment surface configured to contact an outwardly extending member of the medical article so as to inhibit longitudinal movement of the medical article relative to the retainer.

21. A retainer for securing a medical article, 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 at least ingress of a portion of the medical article into the channel;

at least one retention member coupled to the body member and having a distal end, at least a portion of the distal end being disposed in the channel so as to contact an outer surface of the portion of the medical article when the medical article is secured within the retainer; and

a first support and a second support, each support being coupled to the body member so as to rotate between a first position and a second position, the first and second supports deflecting the body member when in the second position so as to increase a lateral dimension of the longitudinal access opening.

22. A method for releasably anchoring an elongated medical article, the method comprising:

providing a retainer having a body comprising at least one retention member, a channel which extends through at least a portion of the body, and a longitudinal access opening disposed on an underside of the body to allow at least ingress of a portion of the medical article into the channel, the at least one retention member being pivotably coupled to the body so as to move between at least a first position and a second position, the at least one retention member extending into the channel;

inserting the portion of the medical article through the access opening and into the channel; and

deflecting the at least one retention member from the first position to the second position so as to secure the medical article in the channel.
