Abstract
A pinch valve, a chip including a pinch valve of this type, a peristaltic pump including a pinch valve of this type and a method for manufacturing same. The pinch valve includes a first substrate, a second substrate, and a third substrate, the third substrate being farmed from an elastic material and situated between the first and second substrates, the first substrate adjoining the third substrate and having at least one first recess on the side adjacent to the third substrate, the second substrate adjoining the third substrate and having at least one second recess on the side adjacent to the third substrate, the first recess and the second recess being situated at least partially opposite each other.
