Abstract

A pinch valve, a chip including the pinch valve, a peristaltic pump including the pinch valve and a method for manufacturing the pinch valve. The pinch valve includes a first substrate, a second substrate, and a third substrate. The third substrate is formed from an elastic material and situated between the first and second substrates. The first substrate adjoins the third substrate and includes at least one first recess on the side adjacent to the third substrate. The second substrate adjoins the third substrate and includes at least one second recess on the side adjacent to the third substrate. The first recess and the second recess are situated at least partially opposite each other.
