Abstract

A securement device includes a simply-structured retention mechanism that permits a portion of a catheter hub or a similar medical article to be easily anchored to a patient, without the use of tape or needles and suturing. A unitary retainer desirably includes a base defining a locator mechanism. The locator mechanism interacts with a fitting of the medical device so as to position the medical device relative to the retainer. The locator mechanism also desirably guides the medical device fitting into contact with an adhesive member mounted on an outer surface of the retainer. In one form, the locator mechanism includes one or more posts that engage mating holes defined in the medical device fitting. In other forms, the locator mechanism includes a cradle defining an arcuate channel to receive a convex surface of the medical device, or a recess shaped to matingly receive the fitting. The retainer is attached to a flexible anchor pad that includes an adhesive bottom surface, which can be attached to the patient'"'"'s skin. In use, a health care provider positions the medical device fitting on the retainer in a position established and guided by the locator mechanism, and attaches the fitting to the retainer via the adhesive member.

Claims

1. A securement device for securing a medical line to a body of a patient, the medical line having a fitting that includes a pair of laterally extending wings, the securement device comprising:

a base layer having a mounting surface at least partially covered by an adhesive for attaching the securement device to the body of the patient, and a receiving surface accessible from an opposite side of the first base layer, a retainer layer disposed on the first base layer and having a peripheral edge, and at least one interior wall formed by the retainer layer, the interior wall extending generally normal to the receiving surface and being disposed within the peripheral edge of the retainer layer, the interior wall and the receiving surface of the base layer together defining at least a portion of a space at least when the fitting is retained by the securement device, the space being configured to receive at least a portion of one of the laterally extending wing of the fitting.

2. A securement device as in claim 1, wherein at least a portion of the space has at least one dimension that is generally similar to a dimension of the corresponding laterally extending wing and is sized in a longitudinal direction so as to not be larger than the wings, the internal wall being configured to interact with the fitting for coarsely positioning the fitting on the receiving surface.

3. A securement device as in claim 1, wherein the space generally matches the dimensions of the wings.

4. A securement device as in claim 1, wherein the retainer layer is generally coextensive with the base layer.

5. A securement device as in claim 1, wherein the retainer layer comprises a plastic polymer.

6. A securement device as in claim 1, wherein the base layer comprises a laminate structure with an upper foam layer and the adhesive.

7. A securement device as in claim 1, wherein an adhesive coating covers at least a portion of the receiving surface.

8. A securement device as in claim 1, wherein the interior wall forms a shape that substantially matches the shape of the laterally extending wings.

9. A securement device as in claim 1, wherein the base layer and the retainer layer are made of similar materials.

11. A seeurement device as in claim 1, wherein the base layer is generally disposed parallel to the retainer layer.

12. A securement device as in claim 1, wherein the interior wall of the retainer layer does not extend above the fitting at least when the fitting is retained by the securement device.

10. A securement device for securing a fitting to a body of a patient, the fitting having laterally extending wings, the securement device comprising:

a generally planar base layer having a mounting surface at least partially covered by adhesive for attaching the securement device to the patient'"'"'s body, and a receiving area oriented so as to face away from the patient'"'"'s body and positioned to contact at least portions of the laterally extending wings of the fitting, the mounting surface being defined on one side of the base layer and the receiving area being accessible from an opposite side of the base layer; and

a retainer layer being attached to an upper side of the base layer and having an internal wall, the internal wall extending through the retainer layer so as to expose the receiving surface of the base layer at least when the fitting is retained by the securement device, the internal wall being configured to interact with the fitting so as to coarsely position the fitting on the receiving area relative to the retainer layer.
