Abstract: An injection system has: an injection device that injects a drug solution; and a sound detection device that detects sound while a subject is being imaged and generates first data based on the sound, wherein the injection device has a data generation unit that acquires the first data, and a history generation unit that generates injection history data of the drug solution, and the data generation unit generates second data in which the first data is associated with time data in common with the injection history data.

Abstract: A safe and easy handling of a chemical-liquid circuit having various components. The opening/closing unit drive mechanism includes an opening/closing unit holder which detachably holds an opening/closing unit which includes a housing having flow channels and a piston for opening and closing the flow channels which is movably provided to the housing, a hook to be engaged with the piston of the opening/closing unit, which is disposed leaving a space from the opening/closing unit holder, and a linear motion mechanism which moves the hook back and forth. The opening/closing unit holder is movably supported between a first position at which the piston is engaged with the hook and a second position at which the piston is not engaged with the hook.

Abstract: An injection system includes: a syringe having a cylinder to be filled with a chemical liquid, a flange projecting laterally from the cylinder, an end portion through which the chemical liquid passes when the chemical liquid is pushed out, and a syringe screw portion formed on a side opposite to the end portion; an adapter for holding the syringe, the adapter having a receiving portion for receiving the cylinder, a regulating wall for abutting the flange, and an adapter screw portion engaged with the syringe screw portion; and an injection device provided with a holder to which the adapter is to be attached. In this injection system, a tightening direction by the syringe screw portion and the adapter screw portion is set in a direction toward the end portion.

Abstract: An injection system has: a gasket having multiple engaging claws, and a distal end portion having across-sectional shape in which a length in a height direction of the cross-sectional shape is longer than a length in a width direction; a ram engaged with the gasket; a cylinder into which the gasket is inserted; and an injection device configured to move the ram and injecting a chemical solution in the cylinder. Each of the engaging claws includes an inner surface which defines a hole having an inlet with an enlarged diameter and inclined in a direction away from a perpendicular line passing through a center of the hole. The engaging claws are displaced between a widened position and a narrowed position. Two engaging claws aligned in the height direction have the same shape and size, and two engaging claws aligned in the width direction have the same shape and size.

Abstract: In a chemical liquid injection conduit, there is a need to prevent a backflow of body fluid of a subject reaching the inside of a common conduit portion. This is solved by the chemical liquid injecting apparatus that includes: a common conduit portion that flows a chemical liquid from a chemical liquid injector to a replaceable conduit portion; a control device that controls the chemical liquid injector; and a flow blocking unit that is arranged inside the replaceable conduit or in a conduit of a boundary portion between the replaceable conduit and the common conduit portion, and by receiving a command from the control device, is switchable between an open state allowing a flow of the chemical liquid and a closed state blocking a flow of the chemical liquid.
