Abstract

A medical article securement device 100 holds a medical article 300 such as a catheter hub or a connector fitting in position upon the body of a patient and inhibits movement of the medical article relative to the patient. The medical article 300 includes an elongated body 430, a pair of outwardly extending wings 301(a), 301(b), and a port 305. The securement device 100 includes a retainer 120 and at least one anchor pad 110. The retainer 120 forms a channel 140 into which at least a portion of the medical article 300 is secured. The retainer 120 includes at least one abutment that abuts against a contact point or surface on the port 305. The anchor pad 110 includes an adhesive layer that is attached to both an epidural layer of a patient and at least a portion of the pair of wings 301(a), 301(b).

Claims

1. A medical article securement system comprising:

a medical article comprising,

an elongated body having a longitudinal axis,

a pair of wings extending away from the elongated body, and

a port disposed on the elongated body and forming a contact surface, the port and the pair of wings being disposed along the longitudinal axis of the elongated body at the same general location;

at least one anchor pad including a lower adhesive surface for contacting both an epidural layer of a patient and at least a portion of the pair of wings; and

a retainer comprising,

a body member having a channel formed therethrough about a channel axis, the channel having a longitudinal length for receiving at least a portion of the elongated body and permitting access to the port at least when the medical article is secured within the channel, the body member having a longitudinal access opening disposed on an underside of the body member to allow at least ingress of the portion of the elongated body into the channel,

at least one abutment extending generally normal to the channel axis and configured to abut the contact surface on the port so as to inhibit longitudinal movement of the medical article relative to the retainer in at least one direction, and

at least one support disposed on the underside of the body member and to a side of the access opening opposite the channel axis, the support attached to the at least one anchor pad.

2. The system of claim 1, wherein the at least one abutment is a surface on a proximal end of the body member along the axis of the channel.

3. The system of claim 1, wherein the at least one abutment is a surface on a distal end of the body member along the axis of the channel.

4. The system of claim 1, wherein the medical article is a catheter hub.

5. The system of claim 1, wherein the medical article further comprises a spin nut having a diameter greater than the diameter of the elongated body.

6. The system of claim 1, wherein the port comprises a septum.

7. The system of claim 1, wherein the channel has an arc length of greater than 180°

.

8. The system of claim 1, wherein the channel has a first tapering shape.

9. The system of claim 8, wherein the channel has a second tapering shape.

10. The system of claim 9, wherein the first tapering shape and the second tapering shape cooperate together when the medical article is inserted into the channel to limit longitudinal movement of the medical article in a first direction.

11. The system of claim 1, wherein the retainer comprises a retention surface for inhibiting transverse motion of the medical article relative to the retainer.

12. The system of claim 11, wherein the retention surface is a movable wall.

13. The system of claim 11, wherein the retention surface is located in the channel.

14. The system of claim 13, wherein the retention surface provides a snap-fit securement with the portion of the medical article.

15. The system of claim 13, wherein the retention surface flexes when the medical article is inserted into the channel.

16. A system for securing a medical article to a patient comprising:

a medical article comprising,

an elongated body having a longitudinal axis,

a pair of wings extending in opposite lateral directions from the elongated body, and

a port disposed on the elongated body and extending generally in a transverse direction, the port being generally aligned with the pair of wings along the longitudinal axis;

a retainer comprising,

a body member having a channel formed therethrough about a channel axis, the channel receiving at least a portion of the elongated body and permitting access to the port at least when the medical article is received within the channel, the body member having a longitudinal access opening disposed on an underside of the body member to allow at least ingress of the portion of the elongated body into the channel, and

a pair of supports disposed on the underside of the body member and to the sides of the access opening opposite the channel axis; and

a pair of anchor pads attached to the pair of supports, the anchor pads including a lower adhesive surface for contacting both an epidural layer of a patient and at least a portion of each wing such that the wings are secured relative to both the epidural layer of the patient and the retainer.

17. The system of claim 16, wherein the body member is spaced from the port along the longitudinal axis when the anchor pads are attached to at least a portion of each wing.

18. The system of claim 16, wherein the port comprises a contact surface and the retainer comprises at least one abutment extending generally normal to the channel axis, the at least one abutment abutting the contact surface of the port so as to inhibit longitudinal movement of the medical article relative to the retainer.

19. The system of claim 18, wherein the contact surface is disposed on a distal side of the port.

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

providing a medical article comprising an elongated body having a longitudinal axis, a pair of wings and a port extending away from the elongated body at generally the same location along the longitudinal axis, the port defining a contact surface disposed on a distal side of the port;

providing a retainer comprising a body member and two anchor pads, the body member having a channel formed therethrough, the channel being configured to receive the medical article, and at least one abutment extending generally normal to the channel;

pressing the medical article into the channel through an opening formed on the underside of the retainer such that the port remains accessible and the medical article is inhibited from moving in both transverse and lateral directions,

abutting the contact surface on the port against the at least one abutment on the retainer so as to inhibit longitudinal motion of the medical article relative to the retainer in a first longitudinal direction; and

adhering the anchor pads to at least a portion of the pair of wings so as to inhibit longitudinal motion of the medical article relative to the retainer in a second longitudinal direction.
