摘要： A fluid transportation system includes: a micropump provided with a chamber and a diaphragm driven by an actuator; fluid communication sections communicating with both ends of the chamber of the micropump; a pressure absorbing section that is provided at least one of the fluid communication sections so as to absorb or reduce a fluid vibration pressure; and a narrow section that is provided at a position further than the pressure absorbing section from the chamber so as to narrow a flow path cross-section, wherein, when R represents a flow path resistance value of the narrow section and C represents an acoustic capacitance value of the pressure absorbing section, a value obtained by multiplication between R and C is not smaller than a driving cycle period value of the micropump.

摘要： A testing microchip includes a specimen storage section; a reagent storage section; a reaction section; a testing section for a test of a reaction product obtained from the reaction; a liquid feed control section; and a gas bubble trapping structure. The sections are connected continuously by a series of flow channels. The liquid feed control section stops passing of liquid until a liquid feeding pressure reaches a predetermined pressure, and passes the liquid when the liquid feeding pressure becomes higher than the predetermined pressure; and the gas bubble trapping structure traps a gas bubble in the liquid that flows in the flow channel so that the gas bubble does not flow to the downstream side and only the liquid passes to the downstream side. A testing apparatus that performs testing in the testing section of the testing microchip, wherein the testing microchip is attachably and detachably mounted to the apparatus.
