Thank you for viewing. This is an adapter specifically for semi-solid enteral nutrition. Contains 20 pieces. This adapter is used to connect semi-solid formulas like Semi-Solid Lacol and Inosolid to pressure bags or gastrostomy tubes for administration into the stomach. I accidentally purchased these, so they are unused, but I opened one to check the type. It has only been opened and not used. (See photo 7) Compliant with ISO80369-3. Cannot be connected directly to a syringe. #AdapterForSemiSolidFormula #SemiSolidFormulaConnector #SemiSolidLacol #SemiSolidInosolid #Administration #Gastrostomy
