Specific tubing and equipment for enteral nutrition. (A) Gastric tubing with specific adapter for connecting enteral feeding tubings with built-in three-way stopcock, to which only specific food syringes can be connected. (B) and (C) Specific entry of a gastric tubing, which has a larger opening of 5 mm in diameter for connection of specific food syringes of different sizes (1 ml, 3 ml, 5 ml, 10 ml and 20 ml). Food syringes (color purple) have a larger cone with a diameter of 4 mm in comparison to an intravenous syringe (color green) cone (diameter 3 mm) for intravenous infusion systems. The intravenous syringe cone (green syringe) is too small and does not fit into the entry of gastric tubing (color purple). An additional safety feature is the consistent color coding (purple) for all parts used for the application of food.
