MEDICAL FLUID ACCESS DEVICE WITH ANTISEPTIC INDICATOR

摘要

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. The indicator includes a substrate and a microporous layer disposed on the substrate. The microporous layer is made from a polymer material having an index of refraction from about 1.25 to about 1.6 and is configured to change from a substantially opaque state to a substantially transparent state upon exposure to an antiseptic solution. The microporous layer resumes the substantially opaque state after a period of time.
