Universal catheter anchoring system
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.
1. A retainer for securing a medical article to a patient, the medical article having two apertures, comprising:
a pad having a lower surface, at least a portion of the lower surface being covered by an adhesive for attaching to the patient;
a base supported by the pad and having a central opening;
a post platform supported by the base;
an attachment button disposed within the central opening, the attachment button limiting movement of the post platform in at least a transverse direction relative to the base;
a first post extending from the base and being configured to fit within at least one of the two apertures in the medical article; and
a second post extending from the post platform and being configured to fit within at least one of the two apertures in the medical article, the second post being movable relative to the first post so as to vary a distance between the first and second posts.
2. The retainer of claim 1 , wherein the distance between the first and second posts varies along a lateral direction.
3. The retainer of claim 1 , wherein the distance between the first and second posts varies along a longitudinal direction.
4. The retainer of claim 1 , wherein the distance between the first and second posts varies along an axis that is skewed relative to a lateral direction.
5. The retainer of claim 1 further comprising at least one cover, the at least one cover being coupled to the base so as to move between an open position and a closed position.
6. The retainer of claim 5 , wherein the at least one cover is disposed above at least a portion of the base when in the closed position.
7. The retainer of claim 5 , wherein the at least one cover comprises a groove, at least a portion of one of the first and second posts being disposed in the groove when the at least one cover is in the closed position.
8. The retainer of claim 7 , wherein the groove inhibits longitudinal movement of the post relative to the at least one cover when the at least one cover is in the closed position.
9. The retainer of claim 1 , wherein the base is circular.
10. The retainer of claim 1 , wherein the base is square.
11. The retainer of claim 1 , wherein the base is trapezoidal.
12. A retainer for securing a medical article to a patient, the medical article having two apertures, comprising:
a base;
a first post platform supported by the base;
a second post platform supported by the base;
a first post extending from the first post platform and being configured to fit within at least one of the two apertures in the medical article; and
a second post extending from the second post platform and being configured to fit within at least one of the two apertures in the medical article, the second post platform being movable relative to the first post platform so as to vary a distance between the first and second posts.
13. The retainer of claim 12 further comprising an attachment button, the attachment button limiting movement of at least one of the first and second post platforms in at least a transverse direction relative to the base.
14. The retainer of claim 13 further comprising a pad having a lower surface and supporting the base, at least a portion of the lower surface being covered by an adhesive for attaching to the patient.
15. A retainer for securing a medical article having at least two apertures to the body of a patient, comprising:
a base defining a plane;
a platform supported by the base;
a first post extending from the base; and
a second post extending from the platform, the platform being movable in a direction parallel to the plane between a first position and a second position so as to vary a distance between the first and second posts.
16. The retainer of claim 15 further comprising a pad having a lower surface and supporting the base, at least a portion of the lower surface being covered by an adhesive for attaching to the patient.
17. The retainer of claim 15 further comprising at least one cover, the at least one cover being coupled to the base so as to move between an open position and a closed position.
18. The retainer of claim 15 , wherein the distance between the first and second posts when in the first position is greater when measured in at least a lateral direction than when in the second position.
19. The retainer of claim 15 , wherein the distance between the first and second posts when in the first position is greater when measured in at least a longitudinal direction than when in the second position.
20. A retainer for securing a medical article having at least two apertures to the body of a patient, comprising:
a base;
at least one post platform slidingly disposed on the base; and
two posts, at least one of the two posts being disposed on the at least one post platform so as to move relative to the other post, the two posts being spaced apart so as to be received within the at least two apertures in the medical article.
