Abstract: An apparatus for filling and sealing intravenous solution bags in a sterile environment. Each bag has a weldably sealable opening for introducing intravenous solution into the bag. The apparatus includes a generally sealed enclosure defining an enclosed interior space sized and shaped for simultaneously containing a plurality of the intravenous solution bags to prevent contamination of the bags. Further, the apparatus includes an intravenous solution delivery system positioned at least partially inside the interior space of the enclosure for delivering intravenous solution through the openings of the bags to fill the bags while the bags are in the enclosure. In addition, the apparatus includes a welder positioned at least partially inside the interior space of the enclosure for hermetically sealing the openings of the bags after they have been filled with intravenous solution and while they are in the enclosure.
