New double-bag system in Japan

An unusual double-bag system is being used for delivery of liquid for enteral nutrition in various Japanese hospitals. The system includes an aseptically filled inner Elopouch® bag, the kind often used for UHT milks.

Elopouch was developed through a strategic alliance between Elopak (New Hudson, MI) and Robert Bosch (Bridgman, MI) GmbH. The outer nutriBag® was designed and developed by Nutrichem, of Ross, Germany.

Relying on ultraclean packaging equipment, Nutrichem places the filled Elopouch into the nutriBag. In use at the hospital, a special fitment on the nutriBag penetrates the Elopouch, releasing its liquid contents into the nutriBag. The fitment on the nutriBag also has a tube through which the liquid is delivered directly to the patient’s stomach or small intestine. Unlike glass bottles traditionally used for enteral nutrition, the nutriBag is light, it won’t break and it eliminates the need to fill into another container. Its cost relative to other delivery systems was not available at press time.
