Abstract

A medical article securement device holds a medical article in position upon the body of a patient and can be used to inhibit lateral and longitudinal motion of the medical article. The securement device includes a retainer with a base and at least one post, and at least one cap. The cap is attached to the base of the retainer by a flexible connection, and can be placed into either a covered or uncovered configuration with respect to the post. The cap includes a recess which can receive a protrusion at the end of the post of the retainer. By placing the post through an appropriate opening in the medical article to be retained and then securing the medical article to the retainer by placing the cap into the covered position over the post, longitudinal and lateral motion of the medical article is inhibited.

Claims

1. A retainer for securing a medical article to the skin of a patient, the retainer comprising:

a base having a lower surface and an upper surface;

two posts disposed on the base, each post having a shaft and a protrusion disposed near a distal end of the shaft;

a receiving area disposed on the base and between the two posts; and

two caps, each cap being attached to the base by a flexible connection and having an internal recess, each cap being movable between a covered configuration in which the protrusion is engaged with the recess of the cap, and an uncovered configuration, wherein the protrusion is held within the recess of the cap by a snap-fit arrangement between the protrusion and the cap.

2. The retainer of claim 1, wherein each cap further comprises an opening disposed at an open end of the recess, the opening being narrower than the recess.

3. The retainer of claim 1 further comprising an anchor pad supporting the retainer and having an upper surface and a lower surface, at least a portion of the lower surface being covered by an adhesive.

4. The retainer of claim 1, wherein each cap comprises a tab that extends from the cap to provide a surface upon which a medical practitioner may press to remove the cap from the post when the cap is in the covered configuration.

5. The retainer of claim 1, wherein the base has a rounded shape.

6. The retainer of claim 1, wherein the protrusion of each post extends to the same extent around the entire circumference of the post.

7. The retainer of claim 1, wherein the protrusion of each post extends in a lateral direction from the post.

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

providing a medical article having an elongated body;

providing a retainer having a base, two posts, and two caps, the two posts being disposed on the base and defining a receiving area there between, each post having a shaft and a protrusion disposed near a distal end of the shaft, each cap being attached to the base by a flexible connection and having an internal recess, each cap being movable between a covered configuration in which the protrusion is engaged with the recess of the cap, and an uncovered configuration;

placing the medical article on the receiving area such that the medical article is disposed at least partially between the two posts; and

moving the two caps to the covered configuration, wherein the protrusion is held within the recess of the cap by a snap-fit arrangement between the protrusion and the cap.

9. The method of claim 8, wherein the medical article comprises at least one hole disposed to a lateral side of the elongated body.

10. The method of claim 9 further comprising inserting at least one post through the at least one hole of the medical article.

11. A securement system comprising:

medical article including a pair of apertures; and

a retainer comprising;

base,

a first post and a second post disposed on the base and configured to extend through the pair of apertures, each of the first and second posts having a shaft and a protrusion disposed near a distal end of the shaft,

a receiving area disposed on the base and between the first post and the second post to receive at least a portion of the medical article,

at least one cap being movable in a direction parallel to the shaft when moving from an open configuration to a closed configuration and having a recess and a collar, the recess engaging the protrusion of at least one of the first and second posts after the protrusion passes through the collar when the cap is moved to the closed configuration so as to inhibit movement of the cap back to the open configuration, wherein the protrusion is held within the recess of the cap in the closed configuration by a snap-fit arrangement between the protrusion and the cap.

12. The securement system of claim 11, wherein the at least one cap is attached to the base by a flexible connection.

13. The securement system of claim 11, wherein the collar is disposed at an open end of the recess and is narrower than the recess.

14. The securement system of claim 11 further comprising an anchor pad supporting the retainer, the anchor pad having a surface at least partially covered by adhesive.

15. The securement system of claim 11, wherein the at least one cap comprises a tab against which a medical practitioner may press to remove the at least one cap from the first post.

16. The securement system of claim 11, wherein the protrusion extends to the same extent around the entire circumference of the first post.

17. The securement system of claim 11, wherein the protrusion extends in a lateral direction from the first post.

18. The securement system of claim 11, wherein at least a portion of the shaft of the first post has a diameter.
