Micro -fluidic chip based on MHD control

The utility model discloses a micro -fluidic chip based on MHD control, this micro -fluidic chip adopts three layer construction based on exchanging MHD drive technique, and the first layer is PDMS cover plate layer 16, leaves electrode spliced pole 12, filling opening 19 and surveys mouthful 20 holes, the second floor is that layer 17 is said to the miniflow, and MHD driving pump 11, miniflow say 15 including exchanging, stock solution room 21 and detect room 22, wherein exchanges MHD driving pump 11 and includes the miniature solenoid coil 14 under electrode spliced pole 12, electrode 13 and the runner 15, the third layer is quartz glass piece 18, the higher authority is carved with the recess of placing miniature solenoid coil 14. Flow into predetermined measuring room 22 analysis and detection under the control that is exchanging MHD driving pump 11 after samples or reagent are injected into to the stock solution room of difference 21, perhaps can the multipath, detect simultaneously, improved detection e
