Title: DRUG SOLUTION INJECTION DEVICE
Abstract:
Provided is a drug solution injection device, for which the size of the overall device can be decreased while reducing the chances of a medical practitioner coming in contact with the drug solution. The drug solution container (3) is provided with: a cylinder (10) with an introducing section (28); a piston (11) provided inside the cylinder (10); and an operating member (12), which is connected to the piston (11) and is for operating the piston (11) from the outside of the cylinder (10). A dynamic force-supplying mechanism comprises a pump (4) capable of supplying dynamic force for driving the drug solution out of the drug solution container (3) by suction of drug solution stored inside a storing chamber (10a) formed between the cylinder (10) and the piston (11). The operating member (12) can be detached from the piston (11).
