Abstract
A pharmaceutical injection device comprises a main body case (2); a pharmaceutical syringe mounting component (3) that is provided inside the main body case (2) and onto which a pharmaceutical syringe (4) is mounted; a piston (5) provided movably with respect to the pharmaceutical syringe (4) mounted onto the pharmaceutical syringe mounting component (3); a drive mechanism (6) for driving the piston (5); a memory (46) that stores a preset pharmaceutical injection schedule; and a controller (7) that resets a current pharmaceutical dose by comparing a planned cumulative pharmaceutical dose, which is a planned cumulative amount of pharmaceutical injected up to the last time on the basis of the pharmaceutical injection schedule stored in the memory, and an actual cumulative pharmaceutical dose, which is a cumulative amount of pharmaceutical actually injected up to the last time.
