<P>PROBLEM TO BE SOLVED: To provide a liquid chemical injection system capable of injecting a plurality of liquid chemicals in an order to a patient by a simple structure. <P>SOLUTION: A liquid chemical syringe 200 filled with the liquid chemical and an extension tube to be connected to the patient are connected through a liquid chemical holding member 500, and a prescribed volume of the liquid chemical different from the liquid chemical syringe 200 is filled in a thin and long flow path in the liquid chemical holding member 500. When the piston member 210 of the liquid chemical syringe 200 is forcibly fitted to a piston member 220, the liquid chemical of the liquid chemical holding member 500 is pushed out by the liquid chemical of the liquid chemical syringe 200. When the liquid chemical is completely pushed out, the liquid chemical of the liquid chemical syringe 200 is pushed out through the liquid chemical holding member 500. Thus, the liquid chemicals of the liquid chemical holding member 500 and the liquid chemical syringe 200 are injected to the patient in the order. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
