Securement device for medical fixtures
A securement device for retaining medical tubing, catheters, and other medical fixtures proximal a patient's skin. The device has a base, at least one channel formed in the base, a flexible strap for overlying the base, and a coupling assembly for coupling the strap to the base. Embodiments for use with Foley catheters include a plurality of channels of differing diameters. Embodiments for use with a peripheral catheter include a single channel for retaining a spin nut. The coupling assembly includes left and right tracks in left and right sides of the base, and left and right rails on an underside of the flexible strap at left and right ends of a body of the strap. The left rail is removably coupled and held within the left track on the base, and the right rail is removably coupled and held within the right track on the base.
1. A securement device for a medical fixture comprising:
a base having a first end portion and a second end portion and a channel for receipt of a medical fixture therethrough;
a flexible strap for securing the medical fixture in the channel during use of the securement device, the flexible strap having a body; and
a coupling assembly for removably coupling the flexible strap to the base, said coupling assembly including—
a first track formed at the first end portion of the base,
a second track formed at the second end portion of the base, and
first and second rails formed on an underside of the body of the flexible strap,
wherein said first rail is removably coupled and held within the first track, and said second rail is removably coupled and held within the second track,
wherein each of the first and second tracks extends longitudinally through the respective first and second end portions of the base but does not extend through an entire longitudinal length of the respective first and second end portions of the base, such that each of the first and second tracks has a closed end and an open end.
2. The securement device of claim 1 , wherein the channel is curved along a generally horizontal plane, such that the medical fixture located in the channel is curved to prevent movement of the medical fixture relative to the base.
3. The securement device of claim 1 ,
wherein the first track is oriented in a first direction relative to the longitudinal length of the first end of the base,
wherein the second track is oriented in a second direction relative to the longitudinal length of the second end of the base,
wherein the first direction is opposite the second direction.
4. The securement device of claim 1 ,
wherein the base further includes a bottom wall, and
wherein the securement device further includes an adhesive pad presenting a top side to which the bottom wall of the base is secured and a bottom side having an adhesive surface for removably coupling with a patient's skin.
5. The securement device of claim 1 , wherein each of the first and second rails formed on the strap has an elongated body extending from the underside of the strap.
6. The securement device of claim 5 ,
wherein the respective elongated bodies of each of the first and second rails formed on the strap has an elongated bead extending from an end of said respective elongated body, and
wherein each of the first and second tracks formed in the base has an interior groove for receipt of the elongated bead of the rail and an exterior bearing for receipt of the elongated body of the rail.
7. The securement device of claim 1 , wherein the channel has a concavity formed along at least a portion of a length of the channel.
8. The securement device of claim 7 , wherein securement of the medical fixture in the channel causes the medical fixture to present an acclivity and a declivity along a vertical axis of the channel.
9. The securement device of claim 7 ,
wherein the channel further includes a bottom wall, and
wherein the concavity extends upwardly from the bottom wall of the channel along a vertical axis of the channel.
10. The securement device of claim 9 , wherein the concavity extends along at least approximately 50% the length of the channel.
11. The securement device of claim 9 ,
wherein the concavity is a first concavity, and
wherein the securement device further includes a second concavity formed in the channel along said at least a portion of the length of the channel.
12. The securement device of claim 9 , wherein a ratio of a largest height of the channel to a height of the channel's concavity is approximately greater than or equal to 2:1.
13. A method of securing a medical fixture comprising the steps of:
providing a securement device including—
a base having a first end portion and a second end portion, a bottom wall, and a channel for receipt of a medical fixture therethrough,
an adhesive pad presenting a top side to which the bottom wall of the base is secured and a bottom side having an adhesive surface for removably coupling with a patient's skin,
a flexible strap for securing the medical fixture in the channel during use of the securement device, the flexible strap having a body, and
a coupling assembly for removably coupling the flexible strap to the base, said coupling assembly including—
a first track formed at the first end portion of the base,
a second track formed at the second end portion of the base, and
first and second rails formed on an underside of the body of the flexible strap, wherein said first rail is configured to be removably coupled and held within the first track, and said second rail is configured to be removably coupled and held within the second track,
wherein each of the first and second tracks extends longitudinally through the respective first and second end portions of the base but does not extend through an entire longitudinal length of the respective first and second end portions of the base, such that each of the first and second tracks has a closed end and an open end;
instructing a user to couple the first rail with the first track, if said first rail is not provided to the user already coupled with said first track;
instructing the user to secure the base to the adhesive pad to the patient's skin;
instructing the user to place the medical fixture within the channel of the base; and
instructing the user to pull the strap over the base, including over at least a portion of the medical fixture located in the channel, and couple the second rail within the second track.
14. The method of claim 13 , wherein the channel is curved along a generally horizontal plane, such that the medical fixture placed in the channel is curved to prevent movement of the medical fixture relative to the base.
15. The method of claim 13 ,
wherein the first track is oriented in a first direction relative to the longitudinal length of the first end of the base,
wherein the second track is oriented in a second direction relative to the longitudinal length of the second end of the base,
wherein the first direction is opposite the second direction.
16. The method of claim 13 , wherein each of the first and second rails formed on the strap has an elongated body extending from the underside of the strap.
17. The method of claim 16 ,
wherein the respective elongated bodies of each of the first and second rails formed on the strap has an elongated bead extending from an end of said respective elongated body, and
wherein each of the first and second tracks formed in the base has an interior groove for receipt of the elongated bead of the rail and an exterior bearing for receipt of the elongated body of the rail.
18. The method of claim 13 , wherein the channel has a concavity formed along at least a portion of a length of the channel.
19. The method of claim 18 , wherein upon the medical fixture being placed within the channel of the base, the medical fixture presents an acclivity and a declivity along a vertical axis of the channel.
20. The method of claim 18 ,
wherein the channel further includes a bottom wall, and
wherein the concavity extends upwardly from the bottom wall of the channel along a vertical axis of the channel.
