Abstract

A medical device, such as a vascular access device, is disclosed for providing access to a medical fluid flow path for the introduction or withdrawal of medical fluids to and from the flow path. The access device includes an indicator for providing a visual indication when the access device has been exposed to an antiseptic agent.

Claims

1. A medical fluid access device comprising:

an access site for the introduction or withdrawal of medical fluids; and

an antiseptic indicator comprising a surface layer including a micropattern configured to selectively reflect one or more wavelengths of light, the micropattern including a plurality of grooves and ridges having a groove spacing between about 0.1 μ

m and about 0.7 μ

m, the antiseptic indicator located at the access site and configured to change from a first appearance to a second appearance upon exposure to an antiseptic agent, and wherein the antiseptic indicator substantially resumes the first appearance after a period of time.

2. The access device of claim 1, including a housing and a valve member, the antiseptic indicator attached to at least one of the housing and the valve member.

3. The access device of claim 1, wherein the antiseptic indicator includes a dye configured to have a first color in the first appearance and a second color in the second appearance.

4. The access device of claim 3, wherein the dye includes a compound having the structure

5. The access device of claim 3, wherein the dye is a merocyanine dye or a salt or derivative thereof, or Reichardt'"'"'s dye or a salt or a derivative thereof.

6. The access device of claim 1, wherein the antiseptic indicator is affixed to the access site by one of solvent bonding, adhesive bonding, sonic welding, melding, molding, laser welding and chemical bonding.

7. The access device of claim 1, further comprising a protective member atop the antiseptic indicator and configured to protect the antiseptic indicator.

8. The access device of claim 1, wherein the micropattern is configured to display an image in the first appearance and the image appears to disappear in the second appearance.

9. The access device of claim 1, wherein the micropattern is a radiation curable resin attached to a surface of the access site.

10. The access device of claim 1, wherein the micropattern is in the form of an image on a surface of the access site.

11. A medical device, comprising:

a medical device having a surface; and

an antiseptic indicator comprising a micropattern including a plurality of grooves and ridges, having a groove spacing from about 0.1 μ

m to about 0.7 μ

m on the surface, the antiseptic indicator configured to change from a first appearance to a second appearance upon exposure to an antiseptic solution, and wherein the antiseptic indicator substantially resumes the first appearance after a period of time.

12. The medical device of claim 11, wherein the device is selected from the group consisting of catheters, drug vial spikes, connectors, vascular access devices, luer access devices, access ports, medication ports, pigtail connectors, prosthetics, endoscopes, bronchoscopes, stethoscopes, and infusion pumps.
