摘要： The priming method includes the steps of: in a state where a contrast agent bag (16) containing a contrast agent (Z) is coupled to a second tube (10B), moving a second piston (512B) in a second syringe (510B) backward to introduce the contrast agent to the second syringe (510B), and with a first tube (10A) kept open, moving the second piston (511 B) in the second syringe (510B) forward to discharge air in the second syringe (510B) to the outside and to fill the first tube (10A) with contrast agent (Z).

摘要： This stopcock flow path switching device includes: a three-way stopcock having a flow path switching cock and provided to, by switching of the flow path switching cock, allow flow path switching between a state in which a contrast agent introducing flow path is formed by coupling a flow path on the patient side to a flow path on the injector head side and a state in which a blood pressure measuring flow path is formed by coupling the flow path on the patient side to a flow path on the blood pressure transducer side; and a clamp mechanism for closing the flow path of the three-way stopcock communicating with the injector head side, in the state in which the blood pressure measuring flow path is formed.

摘要： An injector head for medical use is provided with a position plate serving as both the position plate and a nut, placed at a rear end portion of a plunger, as well as a screw axis engaging with the position plate. A mechanical stopper which can slide only in a direction of an axis of the plunger is provided to the plunger. A female thread is formed on the surface of the mechanical stopper. A main body portion is provided which accommodates the mechanical stopper, the plunger, and the position plate and has a male thread formed on its inner surface and screwed together with the female thread. By utilizing this structure, an injector head for medical use can be provided which is scaled down and simplified while keeping its mechanical safety mechanism.
