A device for the transport of small volumes of a fluid, in particular a micropump or microvalve

摘要

The invention relates to a microfluidic device for the transport of a fluid, in particular a micropump or microvalve. The device according to the invention is characterized by means of foils (2, 3) which, with their flat surfaces of the opposite contact with one another and with limitation of a between the films (2, 3) to be formed of conveying channel (19) are connected to one another, as well as by deflection no directions to the formation of the conveying channel (19) under the joint deflection of the adjoining sheets (2, 3) in a direction perpendicular to the flat surfaces, wherein a deflectable surface area (12) in the direction of deflection of the rear foil (2) within the deflectable, by means of the connection (15) between the films (2, 3) limited surface area (14) in the direction of deflection of the front film (3) is.
