Abstract
A filling system for an anesthetic dispenser has an improved anesthetic-specific code. The adapter neck of the cylinder adapter has polygonally arranged outer surfaces (7, 71) as anesthetic-specific code. A filling device for anesthetics at the anesthetic dispenser has a filler neck for receiving the adapter neck, and polygonally arranged inner surfaces (27, 271) are formed as an anesthetic-specific code at the filler neck, which are designed corresponding to the outer surfaces (7, 71). At least one inner surface (271) has a projection (272) projecting from the inner surface, and at least one outer surface (71) has a depression (72) designed corresponding to the projection (272).
