Abstract

An anchor pad is disclosed having a self-adhesive material applied to one surface of the pad and one or more barbed uprights extending from the opposite surface of the pad in order to securely engage the suture holes of a central line catheter. The barbs permit slidable engagement with the catheter but prevent disengagement. In order to remove the catheter, the barbs can be easily snipped or cut.

Claims

1. An anchoring system for securing a catheter to the body of a patient comprising:

a catheter connector comprising a substantially planar seat having at least one suture hole formed therein; and

an anchoring apparatus comprising;

an adhesive member for secure attachment to the body of the patient; and

at least one retention member mounted on said adhesive member, said retention member being configured to insert through said suture hole of said catheter seat and to engage with the catheter seat about the suture hole to prevent accidental disengagement of said catheter from said adhesive member, whereby the catheter seat is attached to the adhesive member.

4. The apparatus of claim 1, wherein the diameter of said retention member is slightly larger than that of said suture hole.

2. An anchoring apparatus for securing a catheter to the body of a patient wherein said catheter is provided with a substantially planar seat having suture holes formed therein, the apparatus comprising:

an adhesive member for secure attachment to the body of the patient; and

at least one retention member mounted on said adhesive member spaced and configured to correspond with at last one of said suture holes for receiving said seat of said catheter in slidable engagement, said retention member preventing accidental disengagement of said catheter, wherein said retention member is barbed, permitting the planar seat of the catheter to move relative to said retention member in one direction only.

3. The apparatus of claim 2, wherein said apparatus includes a plurality of barbed retention members positioned on said adhesive member so as to be in alignment with said suture holes.

5. A method for attaching an intravenous catheterizaton connector to a body of a patient, wherein the catheterization connector including a substantially planar seat having suture holes formed therein, said method comprising the steps of:

providing an anchoring apparatus having an adhesive member and at least one retention member, said retention member extending outwardly from said adhesive member;

placing said adhesive member on said patient body to secure said anchoring apparatus thereon with said retention member extending away from said patient body; and

inserting said retention member through a suture hole of the catheterization connector planar seat to prevent unintentional disengagement between the retention member and the planar seat of the intravenous catheterization connector.

6. A method for attaching an intravenous catheterization connector to a body of a patient, comprising the steps of:

providing an anchoring apparatus having an adhesive member and at least one retention member, said retention member extending outwardly from said adhesive member;

configuring said retention member with a plurality of barbs radially extending towards said adhesive member acute to a longitudinal axis of the retention member;

placing said adhesive member on said patient body to secure said anchoring apparatus thereon with said retention member extending away from said patient body; and

coupling said intravenous catheterization connector with said retention member in a manner preventing unintentional disengagement between the retention member and the intravenous catheterization connector by inserting said retention member into a hole of said intravenous catheterization connector by elastically deforming said barbs to permit said retention member to insert into said hole but to prevent said retention member from extracting from said hole.

7. The method of claim 6, additionally comprising the steps of:

providing a plurality of retention members corresponding to the number of holes in said intravenous catheterization connector;

positioning said retention members on said anchoring apparatus such that each retention member position corresponds with a hole position of said intravenous catheterization connector.

8. A method for attaching an intravenous catheterization connector to a body of a patient, comprising the steps of:

providing an anchoring apparatus having an adhesive member and at least one retention member, said retention member extending outwardly from said adhesive member;

placing said adhesive member on said patient body to secure said anchoring apparatus thereon with said retention member extending away from said patient body;

coupling said intravenous catheterization connector with said retention member in a manner preventing unintentional disengagement between the retention member and the intravenous catheterization connector; and

severing the retention member between said adhesive member and said connector to permit disengagement between said connector and said adhesive member.

9. An anchoring apparatus for securing a catheterization connector to the body of a patient, wherein said catheterization connector comprises a substantially planar seat having suture holes formed therein, said anchoring apparatus comprising:

an adhesive member for secure attachment to the body of the patient; and

a plurality of retention members mounted on said adhesive member, said retention members being spaced apart from one another such that the spacing between a plurality of retention members correspond with the spacing between a corresponding plurality of suture holes of the connector seat, whereby the connector seat is attached to said adhesive member by inserting said retention members through the corresponding suture hole.

10. An anchoring apparatus for securing a catheterization connector to the body of a patient, wherein said catheterization connector comprises a substantially planar seat having suture holes formed therein, said anchoring apparatus comprising:

an adhesive member for secure attachment to the body of the patient; and

at least one retention member mounted on said adhesive member and configured to insert through a corresponding suture hole of the connector seat and to engage with the connector seat about the suture hole to prevent accidental disengagement of the catheterization connector from said adhesive member, whereby the connector seat is attached to the adhesive member.
