ABSTRACT Multipurpose automatic injector The multipurpose automatic injector for automatic injecting one or more different injection substances in liquid or powder aggregation ensures a several years long period of storage of these different and from each other separated substances and, accordingly, it ensures also the required chemical and pharmacolo- gical stability of the same. The injector according to this invention is very simple to be handled as there are only two operation steps required for it to be used, namely: to remove the safety cover (51) and place the tapered tip (15) of the barrel (10) to the administe- ring place and press it by force not exceeding 45 N. All the other operations are carried out by the injec- tor fully automatically so that, after the complete removal of the air from the chamber containing the substance in powder (40), it carries out mixing of the separately stored substances (40) and (42) and unlocking of the automatic discharge mechanism. This is followed by the emanation of the injection needle (22) from the barrel (10) and its entering into the body and at the same time injecting the injection solution. The injector is again ready for use after the discharge mechanism is afresh locked and a new barrel (10) is inserted with all its inner members and substances into the cylindrical body (50).
