Patent ID: 8747777

Claim:
A microfluidic apparatus comprising: at least one microfluidic device in which fluid channel paths are formed; a device receiving layer including a receiving part into which the at least one microfluidic device is inserted; and a plurality of fluid channel layers disposed on an upper surface of the device receiving layer, the fluid channel layers having fluid channels connected to the fluid channel paths of the at least one microfluidic device, wherein each of the plurality of fluid channel layers includes an upper surface and a lower surface, the lower surface of each of the plurality of fluid channel layers is disposed covering an entire upper surface of an adjacent lower layer thereof to prevent fluid leakage, a lower surface of an inner most fluid channel layer directly contacts the at least one microfluidic device, the inner most fluid channel layer being disposed to cover an entire surface of the upper surface of the device receiving layer, fluid channels of an outermost fluid channel layer comprise an inlet hole through which fluids are introduced into the at least on microfluidic device and an outlet hole through which fluids are discharged to an external environment from at least one microfluidic device, and each of the inlet hole and the outlet hole is passing through the upper surface and the lower surface of the outermost fluid channel layer.
