Abstract
The present invention generally relates to a micropump for the conveyance of fluidic media at low flow rates. The micropump comprises at least one flow duct. The flow duct also has at least three pinch areas. The micropump also includes at least three actuators for the pumping of fluidic media. The actuators are configured and arranged in such a way that a force can be exerted on the flow duct by at least one of the actuators in each of the three pinch regions. This results in the flow duct being narrowed or completely closed at the pinched points and the fluid which is located in this region is completely or partially displaced from this pinched region.
