A simple, practical, low cost barrier device is presented called the TT-Topper (Tracheostomy Tube Topper) to protect healthcare professionals and other caregivers from droplet infection via tracheostomies. The testing of the device using an ultraviolet lit simulation is also demonstrated. The TT-Topper was found to be very effective in curbing droplet spread. It could be used with ease in the community as well as in the hospital setting and could potentially be an adjunct to routine protection standards in clinical care.
