My design is a portable IV device. The device straps onto your bicep, and then gives the astronaut the dose of medicine, saline, or plasma. It will be printed out of flexible filament, such as NinjaFlex. This will be a valuable medical tool, as it can be worn under suits on Mars’s surface, or under normal clothing on the ship. It will allow the astronauts to keep working, even if they need an IV, instead of hauling around a bulky IV stand. The basin for the medicine is refillable, so the tool is reusable, after wash. Overall, I believe this tool will help astronauts on the way, and on Mars.
