PROBLEM TO BE SOLVED: To facilitate a pumping operation for a contrast medium just with use of a commercial syringe. SOLUTION: In commercial syringe CR, a ring shaped first engaging part 53 such that fingers are connected to a cylinder part 51 is formed as a pair and a ring shaped second engaging part 54 such that fingers are connected to a plunger part 52 is formed. A second holding material 12 is installed on the top of a prop 3 of a base material 1 and a first holding material 11 is slidably fitted to the second holding material 12. A protruded first locking part 61 fitting to the first engaging part 53 is formed on the first holding material 11 and a protruded second locking part 62 fitting to the second engaging part 54 is formed on the second holding material 12. A foot pedal 5 installed at ht lower end of the base material 1 and an assembling body K of the holding materials 11 and 12 are connected by a double cable 31. The assembling body K is extended by operating the foot pedal 5 by foot and the plunger part 52 is pushed into the cylinder part 51 to pump the contrast medium in the cylinder part 51. |
