Abstract

An anchoring system includes a device which permits a portion of a catheter or similar medical article to be easily anchored to a patient, desirably without the use of tape or needles and suture. The anchoring system comprises an anchor pad and a retainer mounted upon the anchor pad. The retainer includes at least one clip forming at least a portion of a central channel and that moves generally in a lateral direction to capture the medical article to be retained. In certain embodiments, the clip moves in lateral and transverse directions between closed and open positions. The medical article is secured within the central channel. The channel may have a straight or tapering shape depending on the medical article to be retained.

Claims

1. A securement system, comprising:

a retainer comprising a first clip and a second clip, the first and second clips being slidable in at least a lateral direction with respect to one another to establish a closed condition and an open condition, the first and second clips cooperating to form a channel between the first clip and the second clip, when the retainer is in the closed condition, the first clip having at least one surface which extends in a direction normal to the axis of the channel of the retainer;

an anchor supporting the retainer so that the first and second clips are inhibited from moving generally in the direction normal to the axis of the channel; and

a medical article comprising an elongated body and at least one radially extending member that extends from the elongated body in a direction normal to the axis of the elongated body, wherein the radially extending member of the medical article abuts the at least one surface of the retainer when the retainer is in the closed condition to inhibit longitudinal motion of the medical article through the retainer.

2. A securement system as in claim 1, wherein the radius of the channel tapers along the longitudinal length of the channel.

3. A securement system as in claim 1, wherein the radius of the channel is constant along its longitudinal length.

4. A securement system as in claim 1 wherein the channel of the retainer is formed between a first groove disposed upon the first clip and a second groove disposed upon the second clip such that the first groove and the second groove cooperate when the retainer is in the closed condition to form the channel of the retainer.

5. A securement system as in claim 1 further comprising a first base and a second base, each base being attached to the anchor and having a ratchet element, each of the first and second clips being slidingly mounted in one of the ratchet elements so as to move between the closed condition and the open condition.

6. A securement system as in claim 5, wherein at least one of the first and second bases and one of the ratchet elements are a unitary structure.

7. A securement system as in claim 5, wherein the first base and the second base are a unitary structure.

8. A securement system as in claim 1, wherein the channel additionally comprises at least one annular slot disposed along the length of the channel.

9. A securement system as in claim 8, wherein the at least one surface of the body is a lateral face of the at least one annular slot.

10. A securement system as in claim 9, wherein the radially extending member of the medical article is positioned within the slot of the channel when the radially extending member abuts the at least one surface of the retainer.

11. A securement device for securing a medical article having an elongated body to a body of a patient, comprising:

a flexible anchor having a mounting surface at least partially covered by an adhesive layer for attaching the securement device to the patient'"'"'s body; and

a retainer attached to an upper side of the anchor and having a first clip and a second clip, the first clip having a first groove and the second clip having a second groove, at least one of the first and second clips being slidable in at least a lateral direction so as to define a channel between the first and second clips when in a closed position, the channel being formed by the first and second grooves.

12. A securement device as in claim 11, wherein at least a portion of the surface of the channel extends about a central axis of the channel by more than 180 degrees.

13. A securement device as in claim 11, wherein the channel has a tapering surface.

14. A securement system, comprising:

a retainer comprising a body having a first portion and a second portion, the first and second portions being slidable in a lateral direction with respect to one another to establish a closed condition and an open condition, the first and second portions cooperating to form a channel between the first and second portions when the retainer is in the closed condition, the first portion of the body having at least one surface which extends in a direction normal to the axis of the channel of the retainer; and

a medical article comprising an elongated body and at least one radially extending member that extends from the elongated body in a direction normal to the axis of the elongated body, wherein the radially extending member of the medical article abuts the at least one surface of the retainer when the retainer is in the closed condition to inhibit longitudinal motion of the medical article through the retainer.

15. A securement system as in claim 14, wherein the radius of the channel tapers along the longitudinal length of the channel.

16. A securement system as in claim 14, wherein the channel additionally comprises at least one annular slot disposed along the length of the channel.

17. A securement system as in claim 14, wherein the retainer comprises a latch mechanism disposed between the body and the first and second portions.

18. A securement system as in claim 14, wherein the first and second portions each define a groove.

19. A securement system as in claim 14, wherein at least one of the first and second portions comprises a protrusion, and wherein the body comprises a receptacle configured to receive the protrusion to establish the closed condition.

20. A securement system as in claim 19, wherein a direction of movement of each of the first and second portions includes transverse and lateral components.

21. A securement system as in claim 18, wherein the grooves cooperate together when the retainer is in the closed position to form the channel of the retainer.

22. A method of releasably securing a medical article to a retainer, the method comprising the steps of:

providing a medical article comprising an elongated body and at least one radially extending member that extends from the elongated body in a direction normal to the axis of the elongated body;

providing a retainer comprising a first clip, a first base, a second clip, and a second base, the first clip slidingly engaging the first base and the second clip slidingly engaging the second base, the first and second clips having a closed configuration in which the first and second clips are slid toward each other and relative to the first and second bases, the first and second clips having an open configuration in which the first and second clips are slid away from each other and relative to the first and second bases, the retainer further comprising a first groove disposed upon the first clip and a second groove disposed upon the second clip such that when the retainer is in the closed position the first groove and the second groove cooperate to form a channel, and at least one slot disposed along the length of the channel;

sliding the first and second clips in opposite directions along an axis to place the retainer in the open configuration;

placing the elongated body of the medical article between the first and second grooves of the retainer;

coarsely aligning the radially extending member with the at least one slot; and

attaching the medical article to the retainer by sliding the first and second clips in opposite directions along the axis to place the retainer in the closed configuration and capture the radially extending member in the at least one slot.
