FIELD: medical engineering. SUBSTANCE: device has drug container having liquid inside for making injections. The container has two areas of which the first one is squeezable or flexible and the second one has at least one exit opening through which the liquid is extrudable outside. The flexible area is deformable under changing pressure in the enveloping container. The pressure changes due to gas generator coming into action. The gas generator operation starts due to liquid forced out through the at least one opening mentioned above. EFFECT: high sterility of injections; controlled liquid jet pressure. 36 cl, 21 dwg
