SYRINGE HOLDING STRUCTURE

摘要

A syringe holding structure to which various types of syringes can be easily mounted and which can reliably hold the mounted syringe so that the syringe does not come off. A syringe holding structure (1) is provided with a main adaptor (701) and a sub-adaptor (300) which is detachably mounted to a part of the main adaptor (701). The sub-adaptor (300) is provided with a flange receiver which receives a cylinder flange (211), a flange lock mechanism which locks the cylinder flange when a syringe (200) is rotated 90 degrees about the axis thereof with the cylinder flange received in the flange receiver; and an adaptor affixation mechanism which locks the sub-adaptor to the main adaptor. The sub-adaptor (300) is also provided with an unlocking prohibition mechanism which prohibits the locking effected by the adaptor affixation mechanism from being unlocked while the cylinder flange (211) is locked by the flange lock mechanism.
