NASA\u2019s Northrop Grumman Commercial Resupply Services 24 mission<\/a> along with other supplies, experiments, and hardware. IVGEN Mini will produce IV fluid during demonstrations this spring and fall to verify that the design works as intended in space.<\/p>\nThe system operates by adding space station drinking water to a large supply bag. The bag is connected to IVGEN Mini, which filters the water to remove any particulates and mineral ions. The processed water flows into an output bag that contains premeasured sodium chloride, and the measured combination of both creates sterile, medical-grade IV fluid.<\/p>\n
\u201cFollowing launch, we have tentative operations planned for May,\u201d said Courtney Schkurko, engineering project manager at NASA Glenn. \u201cThe crew aboard the International Space Station will operate IVGEN Mini over the course of two days, and 10 liters of fluid will be generated. Those liters will then be prepared to return to Earth and analyzed to make sure the fluid that was generated in flight meets requirements and is safe to use.\u201d<\/p>\n
The IVGEN Mini system is the second iteration of this technology, originally called IVGEN, which was demonstrated aboard the space station in 2010. The original was much larger because it included additional sensing equipment to prove that the system worked as intended. Following the successful demonstration, the team created a miniaturized version.<\/p>\n
\u201cWith IVGEN Mini, we\u2019ve reduced the system\u2019s size and weight,\u201d Schkurko said. \u201cThe previous system used gaseous nitrogen to pump fluid through the system. Now, we have pumps that are miniaturized, which allow us to optimize our designs and refine the filtering process.\u201d<\/p>\n
In addition to solving the limited shelf life concerns of prepackaged IV fluid, IVGEN Mini also lightens cargo loads. During a deep space mission where crews may spend years in space, cargo must be as lightweight as possible. With IVGEN Mini, NASA won\u2019t need to pack an abundance of IV fluid \u2014 it can be produced as needed if supplies run low.<\/p>\n
\u201cOn a mission to Mars, if you needed to fly 100 liters of IV fluid, those 100 one-liter bags will take up a large amount of space, while IVGEN Mini takes up much less,\u201d Schkurko said. \u201cIt\u2019s that trade between packing IV fluid bags that are likely to expire during the mission or taking a small device and making it as you go. The latter means it will always be within expiration period, it will be available to the crew, and it\u2019s one less risk we have to worry about.\u201d<\/p>\n
Requirements for IVGEN Mini were based on what medical events could occur during a deep space mission, how much fluid it would take to treat those events, and how quickly the fluid can flow through the system. The current system can produce 1.2 liters of IV fluid per hour, which meets these needs. The team also is adhering to United States Pharmacopeia standards, which ensure the system and the fluid it produces meet required pH values and salinity tolerances, and do not contain bacteria, organic carbon, or particulates. Although IVGEN Mini testing will take place aboard the space station, none of the fluid produced will be administered to the crew.<\/p>\n
The IVGEN Mini team is currently planning for shelf-life testing of IV fluid produced by the system as a next phase of this technology. The system is managed by NASA\u2019s Mars Campaign Office as one of the many technologies developed to enable human exploration on the Moon and Mars.<\/p>\n
