Abstract

A catheter anchoring or securement device and system in combination with or for securing a catheter system to a patient'"'"'s skin in a fixed position, the invention having a flexible anchor sheet member having an adhesive backing that adheres the flexible anchor sheet member to the patient'"'"'s skin, a compressible catheter receiving pad mounted to the flexible anchor sheet member, and releasable securing strap covering the compressible catheter receiving pad, wherein the compressible catheter receiving pad is provided with a cavity or recess, the peripheral configuration of which corresponds to the footprint configuration of the catheter body member. The cavity has an axially-oriented channel extending the full width of the flexible anchor sheet member and opposing sets of retention walls defining lateral recesses, the combination of which precludes relative movement of the catheter fitting in all lateral directions.

Claims

1. In combination, a catheter anchoring device and catheter body member;

said catheter body member having a footprint configuration, a thickness and defining an axial direction corresponding to the direction of flow through said catheter body member, said catheter body member receiving one or more catheter tubes;

said catheter anchoring device comprising an adhesive-backed flexible anchor sheet member, a compressible catheter receiving pad mounted onto said flexible anchor sheet member, said compressible catheter receiving pad being composed of a polymer foam material, a cavity disposed in said compressible catheter receiving pad, and a releasable securing strap retaining said catheter body member within said cavity of said compressible catheter receiving pad;

said cavity comprising an elongated channel with open ends, said channel extending fully across said flexible anchor sheet member, said cavity further comprising sets of opposing retention walls, said cavity having a peripheral configuration matching and mating with said footprint configuration of said catheter body member; and

whereby said catheter body member is precluded from horizontal movement in all directions by said sets of opposing retention walls.

2. The combination of claim 1, further comprising an adhesive layer disposed within said cavity.

3. The combination of claim 1, said compressible catheter receiving pad having a thickness substantially equal to the thickness of said catheter body member.

4. The combination of claim 1, wherein one of said sets of opposing retention walls precludes movement of said catheter body member in the direction transverse to the axial direction and another of said sets of opposing retention walls precludes movement of said catheter body member in the axial direction.

5. The combination of claim 1, wherein said releasable securing strap comprises a hook-and-loop fastener assembly.

6. The combination of claim 1, further comprising an adhesive layer disposed on said releasable securing strap, said adhesive layer contacting said catheter body member.

7. The combination of claim 1, wherein said releasable securing strap compresses said compressible catheter receiving pad to define a smooth exterior profile across said catheter anchoring device.

8. In combination, a catheter anchoring device and catheter body member;

said catheter body member having a footprint configuration, a thickness and defining an axial direction corresponding to the direction of flow through said catheter body member, said catheter body member receiving one or more catheter tubes;

said catheter anchoring device comprising an adhesive-backed flexible anchor sheet member, a releasable securing strap mounted onto said flexible anchor sheet member, a compressible catheter receiving pad mounted onto said releasable securing strap, said compressible catheter receiving pad being composed of a polymer foam material, and a cavity disposed in said compressible catheter receiving pad, said releasable securing strap retaining said catheter body member within said cavity of said compressible catheter receiving pad and against said flexible anchor sheet member;

said cavity comprising an elongated channel with open ends, said channel extending fully across said flexible anchor sheet member, said cavity further comprising sets of opposing retention walls, said cavity having a peripheral configuration matching and mating with said footprint configuration of said catheter body member; and

whereby said catheter body member is precluded from horizontal movement in all directions by said sets of opposing retention walls.

9. The combination of claim 8, further comprising an adhesive layer disposed within said cavity.

10. The combination of claim 8, said compressible catheter receiving pad having a thickness substantially equal to the thickness of said catheter body member.

11. The combination of claim 8, wherein one of said sets of opposing retention walls precludes movement of said catheter body member in the direction transverse to the axial direction and another of said sets of opposing retention walls precludes movement of said catheter body member in the axial direction.

12. The combination of claim 8, wherein said releasable securing strap comprises a hook-and-loop fastener assembly.

13. The combination of claim 8, further comprising an adhesive layer disposed on said flexible anchor sheet member, said adhesive layer contacting said catheter body member.

14. The combination of claim 8, wherein said releasable securing strap compresses said compressible catheter receiving pad to define a smooth exterior profile across said catheter anchoring device.

15. In combination, a catheter anchoring device and catheter body member;

said catheter body member having a footprint configuration, a thickness and defining an axial direction corresponding to the direction of flow through said catheter body member, said catheter body member receiving one or more catheter tubes;

said catheter anchoring device comprising an adhesive-backed flexible anchor sheet member, a compressible catheter receiving pad mounted onto the underside of said flexible anchor sheet member, said compressible catheter receiving pad being composed of a polymer foam material, and a cavity disposed in said compressible catheter receiving pad;

said cavity comprising an elongated channel with open ends, said channel extending fully across said flexible anchor sheet member, said cavity further comprising sets of opposing retention walls, said cavity having a peripheral configuration matching and mating with said footprint configuration of said catheter body member; and

whereby said catheter body member is precluded from horizontal movement in all directions by said sets of opposing retention walls.

16. The combination of claim 15, further comprising an adhesive layer disposed within said cavity.

17. The combination of claim 15, said compressible catheter receiving pad having a thickness substantially equal to the thickness of said catheter body member.

18. The combination of claim 15, wherein one of said sets of opposing retention walls precludes movement of said catheter body member in the direction transverse to the axial direction and another of said sets of opposing retention walls precludes movement of said catheter body member in the axial direction.

19. The combination of claim 15, wherein said flexible anchor sheet member compresses said compressible catheter receiving pad to define a smooth exterior profile across said catheter anchoring device.
