US Patent 10330234 Peristaltic pulse dampener

A peristaltic pump dampener apparatus includes a first chamber and a second chamber separated by a flexible diaphragm. The first chamber of the peristaltic pulse dampener apparatus receives a first input flow tangent to the walls of the first chamber, and the second chamber of the peristaltic pulse dampener apparatus receives a second input flow tangent to the walls of the second chamber. The flexible diaphragm of the peristaltic pulse dampener apparatus acts to equalize the pressure between the first chamber and the second chamber so as to generate two substantially even, constant output flows.
