摘要

PROBLEM TO BE SOLVED: To provide a drug solution continuous injection instrument, and a drug solution continuous injection instrument including drug solution, in which temporary rise of flow speed is less likely to occur immediately before completion of injection of drug solution, and flow quantity precision is excellent along the whole injection.;SOLUTION: The instrument is provided with a body container having an open surface on one surface, a lid body engaged with the open surface of the body container, and a balloon installed on the lid body, and provided inside the body container. The lid body is provided with a drug solution injection part that is continuous with the inside of the balloon, and a drug solution feeding part to feed the drug solution stored in the balloon by shrinking force of the balloon. The balloon is repeatedly drawn over a yielding point prior to its use.;COPYRIGHT: (C)2010,JPO&INPIT
