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 such as Semi-Solid Lacol and Inosolid to a pressure bag or gastrostomy tube for administration into a gastrostomy. I accidentally purchased these, so they are unused, but one was opened to check the type. It has only been opened and not used. (See photo 7) Compliant with ISO80369-3. Cannot be directly connected to a syringe. #AdapterForSemiSolidFormula #SemiSolidFormulaConnectorForAspiration #SemiSolidLacol #SemiSolidInosolid #Administration #Gastrostomy
