Abstract

A micropump in the form of a stack comprising, in succession, a flexible diaphragm (2), a pumping chamber (4) and a closing-off plate (3), said pumping chamber (4) communicating with the outside, for example via the flexible diaphragm (2); said diaphragm (2) being furthermore secured to an actuator (5) arranged outside the micropump, characterized in that said diaphragm (2) is secured to the actuator (5) by way of at least one element in the form of a strip (6), which is rigid along its main axis and flexible in the direction perpendicular to its main axis.
