  • Publication number: 20260077121
    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.

  • Publication number: 20210386935
    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.
