Abstract

A 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 distal, longitudinal movement of the medical article. The securement device includes a retainer and at least one anchor pad. The retainer includes an abutment wall and a slot. The slot has a labyrinth shape leading to a cradle part of the slot. At least a portion of the medical article is inserted into the cradle part through the slot. The abutment wall includes at least one abutment that abuts against a contact point or surface on the medical article to inhibit distal, longitudinal movement of the medical article.

Claims

1. A medical article securement system comprising:

a medical article having a longitudinal axis;

at least one anchor pad including a lower adhesive surface configured to attach to a patient'"'"'s skin; and

a body member comprising,

an abutment wall extending generally normal to the longitudinal axis,

a slot in the abutment wall, the slot starting at an access opening and including a cradle portion, the slot being sized to pass at least a portion of the medical article between the access opening and the cradle portion,

a first support and a second support disposed on the underside of the body member and generally on opposite sides of the longitudinal axis, the first support and the second support extend generally along the longitudinal axis and at least one of the first and second supports are attached to the at least one anchor pad, and

a receiving space generally defined on a proximal side of the abutment wall and between the first and second supports, the receiving space being sized to receive at least a portion of the medical article.

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

3. A medical article securement system as in claim 2, wherein the at least one contact surface comprises a surface of the medical article.

4. A medical article securement system as in claim 1, wherein the cradle portion partially surrounds a retained portion of the medical article away from the patient'"'"'s skin.

5. A medical article securement system as in claim 1, wherein the abutment wall inhibits longitudinal movement of the medical article in at least one direction.

6. A medical article securement system as in claim 5, wherein the surface of the medical article extends about the longitudinal axis of the medical article.

7. A medical article securement system as in claim 1, additionally comprising a second anchor pad supporting the body member and ingress into the slot is achieved by passing at least a portion of the medical article between the anchor pads.

8. A medical article securement system as in claim 1, wherein the access opening into the slot is located on a lower side of the abutment wall.

9. A medical article securement system as in claim 1, wherein the access opening is located on an upper side of the abutment wall.

10. A medical article securement system as in claim 1, wherein the access opening is located on a side of the abutment wall.

11. A medical article securement system as in claim 1, wherein the at least one support includes a first mounting wing coupled to the body member and attached to the at least one anchor pad.

12. A medical article securement system as in claim 1 additionally comprising an adhesive, the adhesive adhering to the medical article when the medical article is inserted into the cradle portion.

13. A medical article securement system as in claim 1, wherein a portion of the body member is transparent.

14. A medical article securement system as in claim 1, wherein the slot has an inverted, hook-shape.

15. A medical article securement system as in claim 1, additionally comprising a web member extending between the first and second supports at a location near the abutment wall.

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

at least one anchor pad including a lower adhesive surface configured to attach to a patient'"'"'s skin; and

a body member comprising,

an abutment wall extending generally normal to the longitudinal axis,

a slot having a labyrinth shape between an access opening and a cradle portion, the slot being sized to pass the retained portion of the medical article therebetween, the access opening being disposed on the body member to allow at least ingress of the portion of the medical article into the slot,

a first support and a second support disposed on the underside of the body member and generally on opposite sides of the longitudinal axis, the first support and the second support extending generally along the longitudinal axis and being attached to the at least one anchor pad, and

a receiving space generally disposed on a proximal side of the abutment wall and between the first and second supports, the receiving space being sized to receive at least a portion of the medical article.

17. A retainer as in claim 16, additionally comprising a second anchor pad supporting the body member and ingress into the slot is achieved by passing at least a portion of the medical article between the anchor pads.

18. A retainer as in claim 16, wherein the access opening into the slot is located on a lower side of the abutment wall.

19. A retainer as in claim 16, wherein the access opening into the slot is located on a lower side of the body member.

20. A retainer as in claim 16, wherein the slot has an inverted, hook-shape.

21. A retainer as in claim 16, wherein the slot has a serpentine shape.

22. A method of securing a medical article to a patient, the method comprising:

positioning an elongated medical article on a body of a patient;

providing a retainer having an abutment wall and a slot, the abutment wall extending generally normal to a longitudinal axis of the medical article, at least a portion of the slot forms a cradle to hold at least a portion of the medical article away from the patient'"'"'s skin when the portion of the medical article is secured within the cradle;

inserting the portion of the medical article into the slot through an opening formed on a side of the retainer;

guiding the inserted portion of the medical article through the slot and into the cradle so as to position the medical article in the retainer; and

adhering the retainer relative to a patient'"'"'s skin.
