Abstract

A medical article, such as a catheter hub, is stabilized on a patient with a retainer having a base and clamp or moveable collet. A lever is configured to move the collet in a longitudinal direction relative to the based to secure the medical article to the retainer. When rotated, the lever pulls the collet in a direction away from the patient while collapsing the collet around at least a portion of the catheter hub.

Claims

1. A securement device for securing a medical article to a patient, the device comprising:

an anchor pad having a lower surface, at least a portion of the lower surface being covered by an adhesive; and

a collet supported by the anchor pad, the collet being movable between an open position and a closed position, the collet exerting a radially and longitudinally inward clamping force on the medical article when in the closed position, the collet decreasing in cross-sectional area and moving in a distal direction relative to the anchor pad as the collet moves from the open to the closed position.

2. The securement device of claim 1 further comprising a locking mechanism forming a tapered sleeve, a first portion of the collet being disposed in the sleeve when in the open position and a second portion of the collet being disposed in the sleeve when in the closed position, the first portion being smaller than the second portion.

3. The securement device of claim 1 further comprising a lumen, the lumen being coaxially disposed within the collet and configured to flow a liquid through the medical article and into the patient.

4. The securement device of claim 1 further comprising an actuator, wherein movement of the actuator moves the collet between the open and closed positions.

5. The securement device of claim 1, wherein the collet generally moves along a longitudinal axis thereof.

6. The securement device of claim 1, wherein the collet comprises a plurality of latching members, the latching members applying the clamping force to the medical article when the collet is in the closed position.

7. A securement device for a medical article having a first lumen extending therethrough, comprising:

an anchor pad, at least a portion of a lower surface of the anchor pad being covered by an adhesive;

a base member supported by the anchor pad and forming a second lumen therethrough;

a member movable in a radially and longitudinally inward direction relative to the base member between an open position and a closed position, the member and base member defining a receptacle for receiving at least a portion of the medical article when in the open position; and

a lever moving the member from the open position to the closed position so as to secure a received portion of the medical article relative to the base member and form a flow passage between the first and second lumens.

8. The securement device of claim 7, wherein at least a portion of the member is rotatable with respect to the base member.

9. The securement device of claim 8, wherein the lever is configured to rotate the member from the open position to the closed position.

10. The securement device of claim 8, wherein the lever is rotatable about a longitudinal axis.

11. The securement device of claim 7, wherein the member forms a channel having a generally conical shape that decreases in diameter in a longitudinal direction.

12. The securement device of claim 7, wherein the receptacle extends in a longitudinal direction.

13. The securement device of claim 7, wherein the member is configured to inhibit movement of the medical article in a longitudinal direction when in the closed position.

14. The securement device of claim 7, wherein the received portion of the medical article comprises a catheter hub.

15. The securement device of claim 7, wherein the member comprises a locking mechanism.

16. The securement device of claim 7, wherein the member comprises a clamp.

17. The securement device of claim 16, wherein the clamp comprises a collapsing collet.

18. A retainer for a medical article having a first lumen extending therethrough, comprising:

a base member forming a second lumen therethrough;

a member movable in a radially and longitudinally inward direction relative to the base member between an open position and a closed position, the member and the base member defining a receptacle for receiving at least a portion of the medical article when in the open position; and

a lever for moving the member from the open position to the closed position so as to secure a received portion of the medical article relative to the base member.

19. The securement device of claim 18, wherein the member forms at least a portion of a channel, the channel having a generally tapering shape.

20. The securement device of claim 18, wherein the member comprises a clamp.
