TRACE FLUID CONTROL MECHANISM AND MICROCHIP WITH THE MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide a easy-to-manufacture useful trace fluid control mechanism functioning as an air vent valve or a check valve, and to provide a microchip with the mechanism.;SOLUTION: This trace fluid control mechanism has: a pressure chamber having a prescribed volume; a first microchannel extending into the pressure chamber; and a second microchannel communicating with a peripheral part of the pressure chamber. The circumference of the first microchannel inside the pressure chamber is divided by a gas-permeable partition.;COPYRIGHT: (C)2005,JPO&NCIPI
