  • Patent number: 12611474
    Abstract: The present disclosure discloses a discharge plasma disinfection device and method thereof. In the disinfection device, a gliding arc electrode pair generates the RNS-dominated reactive gas under the excitation of a gliding arc high-voltage power supply; and a dielectric barrier discharge electrode pair generates the ROS-dominated reactive gas under the excitation of a dielectric barrier discharge high-voltage power supply. These two reactive gases are introduced into a mixing chamber in a specific ratio and are subjected to an effective mixing reaction through an internal recycle system to obtain RNS/ROS mixed reactive gas in which reactive nitrogen species and reactive oxygen species coexist. The RNS/ROS mixed reactive gas may be directly configured to perform disinfection, and may also be configured to process an aqueous solution and then perform disinfection by the processed plasma-activated water.

  • Patent number: 12605534
    Abstract: A disinfection cap or device for disinfecting medical connectors. The cap includes a visual indicator that changes color after sufficient scrubbing effort and time have been expended by a clinician to disinfect the medical device, giving positive visual feedback to the treating clinician. An external housing of the cap includes a disinfection medium, such as a disinfectant sponge that is coupled to a rotating collar. The housing is oriented so that the sponge contacts the medical device to be cleaned. Collar rotation in turn rotates the disinfectant sponge against the VAD, providing scrubbing action. A visualization chamber within the cap contains two isolated fluids of distinct colors. As the collar is rotated it mixes the two isolated fluids, changing color of the resultant mixture. When the visualization chamber shows the new, mixed third color, the medical device is disinfected.
