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. An anchoring system for securing a medical article to the body of a patient, comprising:

an anchor pad having an upper surface and a lower surface, at least a portion of the lower surface having an adhesive surface to attach the anchor pad to the body of the patient, and

a retainer mounted on the upper surface of the anchor pad, said retainer being capable of receiving a portion of the medical article, the retainer including a base, at least one post, and a cover assembly, said cover assembly including at least two covers, each cover being connected to the base by a hinge mechanism and being movable about a hinge axis, both hinge axes being generally parallel to each another, and having at least two positions, an open position and a closed position, and at least one post coupled to one of the base and covers, the post being arranged on the retainer so as to at least partially lie between the base and at least one of the covers when said cover is in the closed position, wherein the covers lie on opposite sides of the base relative to a longitudinal axis of the retainer such that a lateral axis intersects both hinge axes, the longitudinal axis being generally parallel to the received portion of the medical article, and the lateral axis being perpendicular to the longitudinal axis.

2. The anchoring system of claim 1, wherein the hinge axes of the covers are configured to be generally parallel to the longitudinal axis of the received portion of the medical article.

3. The anchoring system of claim 1, wherein the base and covers are formed as a unitary piece, the covers being independently adjustable between the closed and the open positions.

4. The anchoring system of claim 1, wherein the covers are configured to lie generally to opposite sides of the retainer in the open position to thereby expose the received portion of the medical article.

5. The anchoring system of claim 1, wherein at least one of the covers has a latching mechanism operating between the base and the cover.

6. The anchoring system of claim 1, wherein each cover has a latching mechanism operating between the base and the cover.

7. The anchoring system of claim 6, wherein each latching mechanism is disposed separately from the at least one post.

8. The anchoring system of claim 1 additionally comprising at least one additional post.

9. The anchoring system of claim 8, wherein each cover extends over at least part of the posts when in the closed position.

10. An anchoring system for securing a medical article to the body of a patient, comprising:

an anchor pad having an upper surface and a lower surface, at least a portion of the lower surface having an adhesive surface to attach the anchor pad to the body of the patient, and

a retainer mounted on the upper surface of the anchor pad, said retainer being capable of receiving a portion of the medical article, the retainer including a base, at least one post, and a cover assembly, said cover assembly including at least two covers, each cover being connected to the base by a hinge mechanism, and having at least two positions, an open position and a closed position, and at least one post coupled to one of the base and covers, the post being arranged on the retainer so as to at least partially lie between the base and at least one of the covers when said cover is in the closed position;

wherein the covers are juxtaposed along a lateral axis and are on opposite sides of the base relative to a longitudinal axis of the retainer such that each cover moves away from the other cover when said cover moves from the closed position to the open position, the longitudinal axis being generally parallel to the received portion of the medical article, and the lateral axis being perpendicular to the longitudinal axis; and

a latching mechanism operating between the base and at least one of the covers and being disposed separately from the at least one post.

11. The anchoring system of claim 10, wherein the base and covers are formed as a unitary piece, the covers being independently adjustable between the closed and the open positions.

12. The anchoring system of claim 10, wherein each cover has a latching mechanism operating between the base and the cover and is independently adjustable between the closed and the open positions.

13. The anchoring system of claim 10, wherein the covers are configured to lie generally to opposite sides of the retainer in the open position to thereby expose the received portion of the medical article.

14. The anchoring system of claim 10 additionally comprising at least one additional post.

15. The anchoring system of claim 14, wherein each cover extends over at least part of the posts when in the closed position.
