Abstract
Damping devices, including damping devices for automated peritoneal dialysis (APD) systems, and associated systems, devices, and methods are disclosed herein. In one embodiment, a damping device includes a body portion, a first membrane, and a second membrane. The body portion can include a first side, a second side opposite the first side, an inlet, and a cavity fluidly coupled to the inlet. The cavity can be defined at least in part by a lumen in the body portion extending from the first side to the second side. The first membrane can be affixed to the first side of the body portion such that the first membrane hermetically seals the cavity at the first side. The second membrane can be affixed to the second side of the body portion such that the second membrane hermetically seals the cavity at the second side.
