Abstract
Abstract An intravenous bottle which dispenses intravenous fluids by gravity feed. The bottle includes a sterile expandable receptacle which is connected to the atmosphere via an inlet port. As the fluid for intravenous injection is dispensed from the bottle, air is drawn into the expandable receptacle. The expandable receptacle acts to prevent the contact of the air from the atmosphere with the fluid to prevent spoilage thereof.
