Abstract

A method of securing a medical article to the body of a patient is disclosed in which an anchoring device comprising an anchor and a retainer is used. The retainer is attached to an upper surface of the anchor and comprises a base, a cover and a post. The base is disposed on the upper surface of the anchor and the cover is connected to the base so as to move between an open and a closed position. When the cover is in the closed position, it lies above at least part of the base. The post is attached movably to either the base or the cover and is arranged so as to lie at least partially between the cover and the base when the cover is in the closed position. When securing a medical article, the cover is placed in the open position and the medical article placed onto the retainer. The cover may then be closed over the medical article and the anchoring device attached to the patient.

Claims

1. A securement device for securing a medical article to a patient, the medical article having an elongated body extending along a longitudinal axis, at least one lumen, and a pair of lateral wings extending in opposite directions from the elongated body on both sides of the at least one lumen, the securement device comprising:

an adhesive bottom layer for attaching to the skin of a patient;

a base member disposed above the adhesive bottom layer;

a post movably coupled to the base member; and

a first cover member and a second cover member being arranged generally in a side-by-side relationship with a gap existing between the cover members, each cover member cooperating with the base member to define a space of sufficient size to receive a wing of the medical article with at least a portion of the elongated body being disposed generally within the gap, each of the spaces defined by each cover having a lateral length wherein the combined lateral lengths of the spaces is greater than a lateral length of the gap.

2. The securement device of claim 1, wherein the first and second cover members move less than 180 degrees between a closed position and an open position.

3. The securement device of claim 1, wherein the first and second cover members have lateral lengths such that at least portions of the covers do not interact with each other at least when the medical article is secured within the securement device and the covers are in their closed position.

4. The securement device of claim 1, wherein each of the first and second cover members includes a skirt that extends about the base member, the skirts interacting with the medical article so as to inhibit movement of the medical article in at least a longitudinal direction relative to the securement device.

5. The securement device of claim 1, wherein the gap is sized to receive a bulky central portion of the elongated body of the medical article.

6. A securement device for securing a medical article which has at least one lumen and a pair of lateral wings extending in opposite directions on both sides of the at least one lumen, to the body of a patient, the securement device comprising:

an adhesive to attach the securement device to the body of the patient;

a lower member disposed above the adhesive;

a post movably coupled to the lower member; and

a cover assembly disposed above the lower member, the cover assembly including two covers, each cover being connected to the lower member and having at least two positions, a first position and a second position, the covers having a lateral length such that at least portions of the covers do not interact with each other at least when the medical article is secured within the securement device and the two covers are in the second position, at least a portion of each wing being disposed between the cover assembly and the lower member at least when the medical article is secured within the securement device and the two covers are in the second position, the combined lateral lengths of the two covers being greater than a lateral distance separating the covers when the medical article is secured within the securement device and the two covers are in their second position, the securement device receiving the medical article when the covers are in the first position.

7. The securement device of claim 6 further comprising flexible couplings between the cover assembly and the lower member.

8. The securement device of claim 6, wherein the covers move less than 180 degrees between the first and second positions.

9. The securement device of claim 6 further comprising a skirt extending about the lower member so as to inhibit movement of the secured medical article relative to the securement device in at least one direction.

10. The securement device of claim 9, wherein the skirt extends from the cover assembly in at least a transverse direction generally toward the lower member so as to inhibit longitudinal movement of the secured medical article relative to the securement device.

11. The securement device of claim 6 further comprising a flange attached to the cover assembly, the flange facilitating movement of the cover assembly relative to the lower member.

12. The securement device of claim 6, wherein the lower member is rigid.

13. A securement device for securing a medical article having at least one lumen and pair of lateral wings extending in opposite directions on both sides of the at least one lumen to a patient, the securement device comprising:

a first portion and a second portion disposed on the first portion, a post movably coupled to the first portion, at least two parts of the second portion generally opposing each other and being spaced apart to define a gap therebetween, the two parts of the second portion being movable relative to the first portion so as to receive a pair of wings between the first and second portions with a portion of the medical article being positioned in the gap, each of the two parts having a lateral length wherein the combined lateral lengths of the two parts is greater than a lateral length of the gap, the two parts of the second portion being independently movable relative to each other, and the second portion extending over and about at least a portion of both wings when the wings are received between the first and second portions.

14. The securement device of claim 13 further comprising an adhesive to attach the securement device to a body of the patient, and wherein the first portion is a base and the second portion is a cover assembly.

15. The securement device of claim 13, wherein the second portion comprises a skirt, the skirt extending about the wings so as to inhibit longitudinal movement of the secured medical article in at least one direction relative to the securement device.

16. The securement device of claim 15, wherein the skirt extends in at least a transverse direction generally toward the first portion so as to inhibit longitudinal movement of the secured medical article relative to the securement device.

17. The securement device of claim 13 further comprising a flange attached to the second portion, the flange facilitating movement of the second portion relative to the first portion.

18. A securement system comprising:

a medical article having a central portion and two wings extending in opposite lateral directions therefrom, the central portion having a transverse height greater than a transverse height of the two wings;

an adhesive to attach the securement device to the body of the patient;

a lower member disposed above the adhesive;

a post movably coupled to the lower member; and

a cover assembly disposed above the lower member and including two covers, the covers having lateral lengths such that a gap is formed between the covers at least when the medical article is secured within the securement device and the covers are in a closed position, the covers being disposed at a transverse height that is greater than the transverse height of the two wings and less than the transverse height of the central portion of the medical article at least when the medical article is secured within the securement device and the covers are in the closed position so that at least a portion of the central portion of the medical article is disposed in the gap.

19. The securement system of claim 18 further comprising skirts, the skirts defining a receiving space between the lower member and cover assembly, and wherein the two covers are arranged over the lower member so as to cover at least a portion of the receiving space when in the closed position, and wherein a first portion of the receiving space receives at least a portion of one of the wings and a second portion of the receiving space receives at least a portion of the other wing.
