Abstract

A fastening device has a support layer, an adhesive layer on one side of the support layer, and a removable liner on the adhesive layer opposite to the support layer, the support layer having an opening therethrough. The device facilitates securing of a catheter or like assembly to a patient. A preferred catheter assembly includes the fastening device, a needle, a cannula and a hub attached to the cannula.

Claims

1. A one-piece fastening device having two opposing ends and two opposing lateral edges extending between the two ends, said device comprising an one-piece support layer, an adhesive layer on one side of the support layer, and a removable liner on the adhesive layer opposite to the support layer, the support layer having an opening therethrough, wherein the opening does not communicate with the edges of the device and wherein said removable liner has an opening commensurate with the opening in the support layer and has two parts, each part having one end on the adhesive layer adjacent to an end of the fastening device and an opposite end of each part extending between the lateral edges of the fastening device, the two parts abutting in a position where a line drawn through the abutting parts would extend through the opening.

2. The fastening device of claim 1 wherein the support layer comprises of a pliant material.

3. The fastening device of claim 2 wherein the pliant material comprises a foamed polymeric material.

4. The fastening device of claim 2 wherein the pliant material comprises a closed cell polyethylene foam.

5. The fastening device of claim 1 wherein the removable liner comprises two adjacent pieces, each piece extending substantially to one side of the opening.

6. The fastening device of claim 5 wherein the adjacent pieces are a polymeric material that releases from the adhesive layer.

7. The fastening device of claim 1 wherein the adhesive layer contains an antibacterial agent.

8. The fastening device of claim 1 wherein the adhesive layer contains an antifungal agent.

9. The fastening device of claim 1 wherein the opening is centrally located.

10. The fastening device of claim 9 wherein the opening has a diameter of about 0.062 inch or greater.

11. The fastening device of claim 10 wherein the diameter is about 0.125 to about 0.156 inch.

12. The fastening device of claim 9 having at least one notch aligned axially with the opening.

13. The fastening device of claim 12 wherein the notch is semicircular.

14. The fastening device of claim 13 wherein the notch is `U` shaped.

15. The fastening device of claim 13 wherein the notch is `V` shaped.

16. An assembly comprising a catheter and the fastening device of claim 1, wherein the catheter comprises a catheter hub and the fastening device circumscribes and is frictionally adhered to the catheter hub.

17. A method of using the fastening device of claim 1 comprising:

a) inserting a catheter comprising a cannula, needle and catheter hub through the opening of the fastening device, thereby circumscribing the catheter hub with the fastening device;

b) pulling the fastening device onto the catheter hub to bend the fastening device away from the needle and toward the catheter hub;

c) inserting the catheter needle and cannula into a blood vessel of a patient;

d) removing the liner from the fastening device; and

e) adhering the fastening device to the patient and to the catheter hub.
