Abstract
Pressure sensors, including pressure sensors for automated peritoneal dialysis (APD) systems, and associated systems, devices, and methods are disclosed herein. In one embodiment, an APD system includes a diaphragm positioned over an opening in a disposable set that includes one or more fluid lines. The diaphragm is affixed to the disposable set about a periphery of the opening. The APD system further includes a pressure sensor configured to measure a pressure of fluid flowing through the disposable set. The pressure sensor includes a load cell and an indenter. The indenter can be moveable along an axis such that, when the diaphragm is aligned with the axis, a convexly curved surface of the indenter can be positioned against the diaphragm. When the indenter is contacting the diaphragm, the load cell can measure a force applied to the load cell by the diaphragm and/or by the fluid flowing through the disposable set.
