PURPOSE: A contrast material pump system is provided to reduce the pollution and causes of troubles by using one-directional clutch bearing to form simply an injection pump and a collection pump. CONSTITUTION: A contrast material pump system includes a storage vessel(3), a collection vessel(5), a first pump(E), a second pump(F), an air supply line, and a control unit. The storage vessel(3) is used for supplying the contrast material. The collection vessel(5) is used for collecting and storing the contrast material. The first pump(E) is used for receiving the contrast material from the storage vessel and injecting the contrast material into a catheter(G) of a large intestine. The second pump(F) is used for collecting the contrast material from the catheter(G). The air supply line is used for supplying the air to the catheter. The control unit controls the first pump(E), the second pump(F), and the air supply line in order to inject and collect the contrast material and the air.
