Abstract

An intravenous catheter anchoring assembly is disclosed and includes a patient-contacting membrane, a platform, and a retaining strap for securing a catheter or tubing of an administration set to a patient. The strap is attached to the platform with adjustable pull-tabs that permit a variety of catheter shapes and sizes to be secured. The strap is also elastomeric so that the strap is stretchable and thereby grabs the secured catheter. The strap and platform further define a plurality of passageways that permit the catheter to be secured in a plurality of non-aligned directions.

Claims

1. An intravenous catheter anchoring device for securing a catheter to a patient, wherein the catheter includes a distal section configured to be at least partially inserted into the patient and a proximal section, the device comprising:

a platform configured for removable attachment to the patient and including a trough and a tubing catch defining an undercut side of the trough, the trough being configured to extend at least partly around the catheter and having a maximum cross-sectional dimension, the tubing catch projecting inwardly relative to the maximum cross-sectional dimension such that the tubing catch contacts and slightly deforms the catheter when the catheter is disposed in the trough so as to restrict axial movement of the secured catheter relative to the platform; and

a retaining strap cooperating with the platform to define a catheter-receiving passageway configured to receive a portion of the catheter with the proximal and distal sections projecting outwardly therefrom, wherein at least a portion of the tubing catch is disposed below the retaining strap so as to partially secure the portion of the catheter prior to attachment of the retaining strap to the platform, and wherein the retaining strap comprises an elastomeric body, the body being elastically stretched when the catheter portion is received in the passageway.

2. The intravenous catheter anchoring device as in claim 1, wherein the trough has an arcuate cross-sectional shape.

3. The intravenous catheter anchoring device as in claim 2, wherein the tubing catch extends radially inward relative to the arc.

4. The intravenous catheter anchoring device as in claim 1, wherein the trough extends about an arc equal to or less than about 180 degrees.

5. An intravenous catheter anchoring device for securing a catheter to a patient, wherein the catheter includes a distal section configured to be at least partially inserted into the patient and a proximal section, the device comprising:

a platform configured for removable attachment to the patient and having a connector, at least one trough, and at least one tubing catch defining an undercut side of the trough, the tubing catch projecting inward relative to the at least one trough such that the at least one tubing catch contacts and slightly deforms the catheter when the catheter is disposed in the at least one trough so as to restrict axial movement of the secured catheter relative to the platform; and

a retaining strap cooperating with the platform to define a catheter-receiving passageway configured to receive a portion of the catheter with the proximal and distal sections projecting outwardly therefrom, the retaining strap having an elongated flexible body with spaced apart opposite ends, one of which is coupled to the platform and the other which is removably attached to the connector, wherein at least a portion of the at least one tubing catch is disposed below the retaining strap so as to partially secure the portion of the catheter prior to attachment of the retaining strap to the platform, and wherein the retaining strap comprises an elastomeric body, the body being elastically stretched when the catheter portion is received in the passageway.

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

a platform having at least one trough and at least one tubing catch defining an undercut side of the trough, the at least one tubing catch projecting inwardly relative to the at least one trough such that the at least one tubing catch contacts and slightly deforms the catheter when the catheter is disposed in the trough so as to restrict axial movement of the secured catheter relative to the platform;

a plurality of connectors disposed on the platform; and

a retaining strap cooperating with the plurality of connectors to define a passageway between the retaining strap and the at least one trough, the passageway being configured to receive a portion of the catheter, wherein at least a portion of the at least one tubing catch is disposed below the retaining strap so as to partially secure the portion of the catheter prior to attachment of the retaining strap to the plurality of connectors, and wherein the retaining strap comprises an elastomeric body, the body being elastically stretched when the catheter portion is received in the passageway.

7. The anchoring device as in claim 6, wherein the body is configured so that strain varies along the length thereof when the body is elastically stretched.

8. The anchoring device as in claim 6, wherein the body includes a plurality of discrete attachment locations spaced along the length of the body, with each of the attachment locations being releasably connectable to at least one of the plurality of connectors.

9. The anchoring device as in claim 6, wherein the body comprises spaced apart pull-tabs.

10. The anchoring device as in claim 9, wherein the pull-tabs are removably attached to a corresponding one of the plurality of connectors.

11. The anchoring device as in claim 9, wherein the plurality of connectors each include a post extending from the platform for receiving the pull-tabs.

12. The anchoring device as in claim 6, wherein the at least one trough has an arcuate cross-sectional shape.

13. The anchoring device as in claim 6, wherein the trough includes opposite ends, the trough sloping downwardly toward one of the ends thereof.

14. The anchoring device as in claim 13 further comprising a stop disposed near one of the ends of the trough so as to resist axial movement of the catheter along the trough in the direction of the stop.

15. The anchoring device as in claim 6, wherein the trough extends at least partially around the catheter portion.

16. The anchoring device as in claim 6, wherein the trough has a maximum cross-sectional dimension and the at least one tubing catch projects inwardly relative to the maximum cross-sectional dimension.

17. The anchoring device as in claim 6, wherein the at least one trough extends about an arc equal to or less than about 180 degrees, and the tubing catch extends radially inward relative to the arc.

18. The anchoring device as in claim 6, wherein the platform includes a plurality of troughs and a plurality of tubing catches.
