Patent ID: 8741231

Claim:
A channel control mechanism for a microchip for performing reaction and analysis of a sample, the microchip comprising: a first member which has a laminated structure formed of members including stretchable members, and comprises: a sample reservoir for packing the sample therein; a reaction reservoir in which mixture and the reaction of the sample are performed; and a channel formed in a middle layer of the laminated structure, for bringing the sample reservoir and the reaction reservoir into communication with each other, the first member performing the reaction and the analysis in such a manner that the sample is delivered into the reaction reservoir through the channel; and a second member which has a laminated structure formed of members including stretchable members, and comprises a pressurizing channel, wherein: the pressurizing channel partially overlaps the channel when the first member and the second member are superimposed on each other; the channel is closed through applying a pressurized medium to the pressurizing channel; and the channel is opened through releasing a pressure of the pressurized medium.
