PROBLEM TO BE SOLVED: To provide a liquid feed device capable of reducing or preventing the mixing possibility of foreign matters from outside by feeding a liquid in a closed system. SOLUTION: Liquid storage parts 1 and 2 comprising a flexible material, first flow channels 3 and 4, liquid sending parts 5 and 6, second flow channels 7 and 8 and a discharge part 10 having a discharge orifice are allowed to successively communicate with each other and a series of these regions are set to the closed system not communicating with the outside excepting the discharge orifice of the discharge part 10. Energy for sending the liquid in the direction of the second flow channels 7 and 8 from the first flow channels 3 and 4 in the liquid sending parts 5 and 6 to discharge the liquid from the discharge orifice the discharge part 10 while respectively deforming the storage parts 1 and 2 to feed the same to the discharge part 10 from the storage parts 1 and 2. The liquids sent from a plurality of the storage parts 1 and 2 reach a detection part 11. COPYRIGHT: (C)2008,JPO&INPIT |
