The device for injection of medicinal preparations, according to the invention, comprises a changeable isolated capsule, an injection needle, and a drive to move pistons, made in the form of a spring-loaded pusher located inside the housing which supports the changeable isolated capsule. The housing has a stopping member to arrest said spring-loaded pusher. Inside said isolated capsule, installed coaxially therewith and with each other are a main piston closed by a partition on the side facing the chamber holding the first medicinal preparation and an additional piston. The partition is movable. The injection needle is installed inside the isolated capsule, fixed on the additional piston, and it in use passes through said partition, and has an aperture in the zone of the partition on the side of the chamber holding the first medicinal preparation. The additional piston is located in the channel of the main piston and limits the chamber for the second medicinal preparation. The drive of the pistons has an additional spring-loaded pusher interacting with the additional piston and is located coaxially with the spring-loaded pusher. The housing of the drive of the pistons has an additional stopping member for the additional spring-loaded pusher.
