NASA relies on intravenous (IV) fluid during crewed missions to treat medical conditions, addressing up to 30% of scenarios such as dehydration and burns. However, the shelf life of prepacked IV fluid is limited to 16 months, which is a challenge for missions lasting up to three years beyond low Earth orbit.
To solve this, scientists at NASA’s Glenn Research Center developed the IntraVenous Fluid GENeration Miniaturized (IVGEN Mini) system. IVGEN Mini converts water into sterile, medical-grade IV fluid on demand by filtering the space station’s drinking water and combining it with premeasured sodium chloride in an output bag, creating a critical liquid for use in orbit.
IVGEN Mini is a smaller, more efficient version of the original IVGEN system demonstrated on the International Space Station in 2010. The updated design eliminates gaseous nitrogen pumps, using miniaturized pumps to improve reliability and reduce mass and size.
The IVGEN Mini was delivered to the International Space Station aboard NASA’s Northrop Grumman Commercial Resupply Services 24 mission on April 11. Planned operations include generating 10 liters of IV fluid over two days, with the fluid returned to Earth for safety and quality analysis.
This technology reduces cargo mass and addresses the shelf life limits of traditional IV supplies, marking a critical step for sustainable medical resources in future deep space exploration missions.
