PROBLEM TO BE SOLVED: To provide an additional injector for medicinal solution that can be expected to attain positive sealing and improvement in the durability of a storage bag. SOLUTION: This additional injector is provided with a casing 1 and an operating cap 2 rotatably supported to the casing 1. A medicinal solution filling storage bag 3 with an upstream solution transport tube 4 and a downstream solution transport tube 5 connected thereto is disposed on the casing side. A plurality of protrusions are provided on the back face side of the operating cap 2, while a stopper 6 abutting one of the protrusions to seal the downstream solution transport tube 5 of the storage bag 3, and a pusher 7 abutting one of the protrusions to discharge the filled medicinal solution in the storage bag 3, are interposed between the casing 1 and the operating cap 2. A means for sealing the downstream solution transport tube 5, and a means for discharging the filled medicinal solution in the storage bag 3, therefore exist separately as the stopper 6 and the pusher 7 so as to make a great contribution to certainty of sealing and durability of the storage bag 3. |
