  • Multi-stage color activated system to detect unauthorized processing of medical devices
    Patent number: 8432279
    Abstract: A medical device (101), such as a blood pressure cuff or other device, includes an unauthorized reprocessing warning (406) printed in a first printable media (103). The first printable media (103) is configured to change from a first state to a second state upon exposure to an applied stimulus (203). A mask (407) is printed on or about the unauthorized reprocessing warning (406) in a second printable media (106). The second printable media (106) is configured to also change state upon exposure to an applied stimulus (203). The unauthorized reprocessing warning (406) is legible only after exposure to the applied stimulus (203). However, application of a reversion stimulus 306 will render the unauthorized reprocessing warning (406) non-legible.
