Fluid control structure of the microchannel, the manufacturing method of the fluid control structure of the microchannel, and closing member operating device

摘要

PROBLEM TO BE SOLVED: To provide a fluid control structure of a micro flow passage having no restriction on a substrate material of a microchip and capable of blocking the flow passage securely to ensure pressure proof property and to provide a blocking member, the microchip, various application devices, and a blocking member operation device.;SOLUTION: This structure is constituted by pushing a valve 30 into a hole 20 of the microchip 1 to block the flow passage FA, a movable part for blocking the flow passage FA is the valve 30 itself, and there is no necessity for blocking the flow passage FA by deforming substrates 11, 12. For this reason, even a hard material can be used in the substrates 11, 12 of the microchip 1 to improve reliability and general-purpose property greatly. Since an elastic member 32 comes into close contact with a peripheral fringe 21 of the hole 20 and an end part 142 of a channel 14 due to elastic deformation, the flow passage FA is securely blocked to ensure pressure proof property. The operation device provided with a pressing means of the valve 30 arranged in the microchip 1 is also provided.;COPYRIGHT: (C)2007,JPO&INPIT
