CHEMICAL LIQUID INJECTING APPARATUS

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.
