Abstract
An apparatus for presenting an application status of a medical device that has a unused state and a used state. The apparatus includes a label having an electrochromic element. The label is at least partially disposed on an exterior surface of the medical device and is configured to display a predetermined feature in response to an electric current. A power source is disposed in or on the medical device for providing the electric current. A switch is configured to selectively connect or disconnect the label and the power source to one another for controlling the application of the electric current to the electrochromic element in response to actuation of the medical device from the unused state to the used state. The label may be scanned by a scan device that may connect to a medical organization for communicating information between the scan device and the medical organization.
