Patent ID: 8480980

Claim:
A thin film bio valve device comprising: at least one chamber for storing a fluid that is used for a biomaterial assay or a biochemical assay or for performing a biological or biochemical reaction; a specimen inlet for loading a specimen; a channel that connects the at least one chamber to allow the fluid to flow; a channel hole that is disposed at the center of the channel and connected to the channel; a magnetic valve for opening and closing the channel hole; a top substrate, an intermediate substrate and a bottom substrate in which the channel, the channel hole and the chamber are formed; a body in which the channel, the channel hole, the chamber, the specimen inlet, and the magnetic valve are integrated by stacking and binding the top substrate, the intermediate substrate and the bottom substrate; and a movable permanent magnet or scan magnet for opening the channel hole, wherein the channel hole is opened or closed by reversibly moving the magnetic valve in a clockwise or counter-clockwise direction due to an attractive force generated between the magnetic valve and the movable permanent magnet or an attractive force generated between the magnetic valve and the scan magnet.
