aseptic system for nutrition of patients with total parenteral nutrition

摘要

An improved flexible, collapsible container (10) for holding a sterile solution such as protein hydrolysate or amino acid solutions is disclosed, it being intended for sterile connection with another flexible, collapsible container (38) of carbohydrate solutions or the like. The two containers carry connector members (24, 34) of a specific design. A flexible tubular boot member (18) is provided to the container of this invention, which carries the connector and a tubular cannula (20) defining an inwardly-pointed spike adapted to penetrate puncturable diaphragm means (17) for opening the contents in sterile manner. The boot member is of a particular shape as disclosed to permit inward deflection of its end without forcing the sides to expand substantially outwardly.
