IVGEN

Abstract

The Exploration Medical Capabilities Element of NASA's Human Research Program chartered the IV fluid GENeration (IVGEN) project at the NASA Glenn Research Center to develop a system that could produce IV fluid in a microgravity environment meeting USP standards. NASA's flight surgeons have identified medical conditions likely to arise during exploration missions of various length and distance from the earth. Adequately treating some of those conditions will require the ability to utilize Intravenous (IV) therapy to either serve as a method for delivering pharmaceuticals that can only be administered via that route, or to hydrate patients that are unable to hydrate themselves. Given that need, NASA currently maintains a reserve of IV fluid on ISS sufficient to treat an astronaut until they can be returned to earth, which is generally within 24 hours. Because such a rapid return will not be an designed to produce United States Pharmacopeia ( USP) grade IV fluid in a reduced gravity p option for missions extending beyond low earth orbit, NASA must either fly as many as 100 liters of IV fluid, with a total mass of 100 Kg, or provide systems that can use vehicle resources to produce such fluid if it is needed. The IVGEN hardware, a compact water purification and mixing system, was environment using available resources.
