Abstract

An anchoring device for securing a catheter to a patient includes a platform and a retaining strap. The platform includes a plurality of connectors extending outwardly from a base, each of the connectors including a head at a distal end of a post. The retaining strap cooperates with the platform to define a catheter-receiving passageway designed to receive a portion of the catheter. The retaining strap may include a first end including a first pull tab and a second pull tab, a second end including a third pull tab and a fourth pull tab, and a stretch portion between the first end and the second end. The retaining strap may also include a plurality of attachment locations, each of the attachment locations including a through-hole designed to receive the head of one of the plurality of connectors.

Claims

1. An anchoring device for securing a catheter to a patient, comprising:

a platform including a plurality of connectors extending outwardly from a base, each of the connectors including a post, each post including a head at a distal end; and

a retaining strap cooperating with the platform to define a catheter-receiving passageway designed to receive a portion of the catheter, the retaining strap comprising;

a first end including a first pull tab and a second pull tab;

a second end including a third pull tab and a fourth pull tab;

a stretch portion between the first end and the second end; and

a plurality of attachment locations, each of the attachment locations including a through-hole, each through-hole designed to receive a respective one of the heads of the plurality of connectors, at least one of the first, second, third and fourth pull tabs including more than one attachment location.

2. The anchoring device according to claim 1, wherein the retaining strap comprises an elastomeric body, the body being elastically stretched when the catheter is retained by the retaining strap.

3. The anchoring device according to claim 2, wherein the body is designed to vary strain along a length thereof when the body is elastically stretched.

4. The anchoring device according to claim 1, wherein at least one of the attachment locations includes reinforced ribs surrounding its through-hole.

5. The anchoring device according to claim 4, wherein the at least one of the attachment locations further includes a deflecting surface.

6. The anchoring device according to claim 5, wherein the deflecting surface forms a conical frustum and the ribs are shaped to provide a countersunk portion.

7. The anchoring device according to claim 1, wherein each of the first, second, third and fourth pull-tabs has a thickness greater than a thickness of the stretch portion.

8. The anchoring device according to claim 7, wherein the thickness of the stretch portion is in a range of about 0.010 inch to about 0.180 inch.

9. The anchoring device according to claim 1, wherein the stretch portion is centrally located to partially define the catheter-receiving passageway.

10. The anchoring device according to claim 1, wherein the retaining strap further comprises a lobe extending from a lower surface thereof, the lobe including a slot for receiving at least a portion of an upstanding wall projecting inwardly from one of the posts of the plurality of connectors.

11. The anchoring device according to claim 1, wherein the retaining strap includes an upper surface and a lower surface, and wherein at least one of the attachment locations includes a reinforced rib, circumscribing its through-hole, on each of the upper surface and the lower surface, each reinforced rib including a deflecting surface tapering inwardly as it extends away from the respective upper surface and lower surface.

12. The anchoring device according to claim 11, wherein the retaining strap further comprises a lobe extending from the lower surface thereof, the lobe projecting radially from at least one of the reinforced ribs, the lobe including a slot for receiving at least a portion of an upstanding wall projecting inwardly from one of the posts of the plurality of connectors.

13. The anchoring device according to claim 1, wherein each head of the plurality of connectors has a diameter larger than a diameter of its post, and wherein each head has a cross-sectional dimension larger than a cross-sectional dimension of the through-hole of each of the attachment locations.

14. The anchoring device according to claim 1, wherein the head of each of the plurality of connectors has a frusto-spherical shape.

15. The anchoring device according to claim 1, wherein at least a portion of the base is rigid.

16. The anchoring device according to claim 1, further comprising a flexible and permeable membrane designed to removably attach the platform to the patient.

17. The anchoring device according to claim 16, wherein the platform and the membrane are adhesively interconnected along a grooved connection surface of the platform.

18. The anchoring device according to claim 1, wherein the stretch portion includes a surface finish of about 125 microinch or less.
