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 fining 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.

Claims

1. A securement device comprising:

a flexible anchor pad having a bottom surface at least partially covered by an adhesive layer; and

a retainer including a receiving area oriented so as to face away from the bottom surface;

an adhesive member disposed within at least a portion of the receiving area and having a shape corresponding to at least a portion of a fitting; and

a pedestal and at least one post being spaced in a generally lateral direction from the pedestal, the at least one post being configured to interact with the fitting so as to orient the fitting at least partially on the receiving area and in contact with at least a portion of the adhesive member, the at least one post being configured to interact with at least one hole in the fitting;

the retainer being attached to an upper side of the anchor pad such that the bottom surface is defined on one side of the anchor pad and the receiving area is accessible from an opposite side of the anchor pad.

2. A securement device as in claim 1, wherein the pedestal extends in a direction away from a patient'"'"'s body.

3. A securement device as in claim 1, wherein the receiving area has a planar shape.

4. A securement device as in claim 3, wherein the planar shape forms an acute angle with the bottom surface.

5. A securement device as in claim 4, wherein the acute angle ranges between about 0 degrees and 15 degrees.

6. A securement device as in claim 1, wherein at least a portion of the adhesive member is located on the pedestal.

7. A securement device for securing a fitting having at least one hole to a body of a patient, the securement device comprising:

an anchor pad;

at least one bottom surface on the anchor pad at least partially covered by an adhesive layer for attaching the securement device to the patient'"'"'s body;

a receiving area at least partially supported by the anchor pad along which the fitting lies when secured by the securement device;

an adhesive member disposed upon the receiving area such that the adhesive member lies in contact with the fitting and the securement device when the fitting is located in the receiving area;

at least one post configured to interact with the at least one hole in the fitting; and

a raised pedestal supported by the anchor pad and being spaced in a generally lateral direction from the at least one post, the pedestal configured to interact with the fitting so as to orient the fitting on the receiving area, the adhesive member at least partially positioned on the raised pedestal; and

a retainer attached to an upper side of the anchor pad, the retainer including the raised pedestal with the receiving area being defined on a side of the retainer facing away from the at least one bottom surface on the anchor pad.

8. A securement device as in claim 7, wherein the anchor pad comprises a foam layer.

9. A securement device as in claim 8, wherein the adhesive layer covers at least a portion of one side of the foam layer.

10. A securement device as in claim 7, wherein a surface of the pedestal forms an acute angle with the bottom surface.

11. A securement device as in claim 10, wherein the acute angle ranges between about 0 degrees and 15 degrees.

12. A securement device as in claim 7, wherein the receiving area has a planar shape.

13. A securement device for securing a fitting, having an elongated body and at least one hole, to a body of a patient, comprising:

a flexible anchor pad having a bottom surface at least partially covered by an adhesive layer for attaching the securement device to the patient'"'"'s body;

a retainer including a receiving area oriented so as to face away from the patient'"'"'s body; and

a pedestal and at least one post, the at least one post being spaced in a generally lateral direction from the pedestal, the receiving area being disposed on the pedestal, the at least one post being configured to interact with the at least one hole and to position the fitting on the receiving area relative to the pedestal;

the retainer being attached to an upper side of the anchor pad such that the bottom surface is defined on one side of the anchor pad and the receiving area is accessible from an opposite side of the anchor pad;

an adhesive member at least partially covering the receiving area and positioned to contact at least a portion of the fitting secured by the securement device.

14. A securement device as in claim 13, comprising at least a pair of posts spaced apart from each other.

15. A securement device as in claim 14, wherein the adhesive member is positioned between the pair of posts.

16. A securement device as in claim 14, wherein the retainer includes an upper surface positioned between the posts, and the adhesive member is located on the upper surface.

17. A securement device as in claim 16, wherein the upper surface forms an acute angle with the bottom surface.

18. A securement device as in claim 13, wherein a foam layer is interposed between the adhesive member and the pedestal.
