Patent ID: 7537028

Claim:
A device for a fluid processor comprising: a plate-shaped base material; a micro conduit completely enclosed within the plate-shaped base material, configured to pass fluid formed in the base material so as to extend in a plane direction thereof; a valve completely enclosed within the plate-shaped base material, configured to open and close the micro conduit, and including a spherical space forming a valve chamber with a valve particle that includes a magnetizable material; and a valve control mechanism, configured to change a position of the valve particle with respect to an opening of the micro conduit linked with the valve chamber to control the valve between a closed state and an opened state, said valve control mechanism including a magnetizable film attached to a top surface of the plate-shaped base material and configured to apply a magnetic field to the valve particle to change the position of the valve particle, wherein the state of the valve is controlled by the valve control mechanism to form the fluid processor.
