1. A mixing device comprising:

  • a swirling flow generating chamber adapted for generating a swirling flow;

    a first inflow opening adapted for introducing a first drug solution into the swirling flow generating chamber in a direction parallel to a central axis of the swirling flow;

    a second inflow opening adapted for introducing a second drug solution into the swirling flow generating chamber so as to generate a swirling flow of the second drug solution having a specific gravity lower than that of the first drug solution in the swirling flow generating chamber;

    an outflow opening adapted for discharging a mixed drug solution of the first drug solution and the second drug solution; and

    a narrowing chamber which is interposed between the swirling flow generating chamber and the outflow opening and has a space continuously narrowed toward the outflow opening.
