Microfluidic coupling device with a variable flow resistance and the microfluidic arrangement

摘要

Microfluidic coupling device (63, 77, 95) comprising:a connection (49, 67, 69),a microfluidic flow path (5, 7), which is at the connection (49, 67, 69) is coupled,a valve spool (1, 35, 53, 65, 79, 97) with a microfluidic control element (3, 13) for controlling the flow within the microfluidic flow path (5, 7),characterized in that the control element (3, 13) of the valve slide (1, 35, 53, 65, 79, 97) a tapering flow path (5, 7) with a variable flow resistance, wherein the tapered flow path (5, 7) an inlet (5,7,47) with an outlet (5, 7, 47), the microfluidic coupling device (63, 77, 95) from a flat more layers of film (103, 105) is built up, and wherein the more layers of film (103, 105) three layers (103, 105) and the valve spool in a central position (103) of the more layers of film (103, 105) is designed.
