    Abstract: Drainage systems for excess body fluids and associated methods are disclosed herein. A drainage system in accordance with an embodiment of the present technology can include, for example, a drainage catheter, a first reference line, a second reference line, and a pressure sensor assembly. The catheter can include a flexible interface member and an inlet can be placed in fluid communication with a site of excess body fluid within a patient. A first flexible region of the first reference line can be in pressure communication with the flexible interface member, and a second flexible region of the second reference line can be in pressure communication with the surrounding atmosphere. The pressure sensor assembly can be spaced apart from the flexible regions, and measure the pressures of the first and second reference lines. This information can be used to determine the pressure at the site of excess body fluid.

    Abstract: The present technology is directed to capillarity-based devices for performing chemical processes and associated system and methods. In one embodiment, for example, a device can include a source configured to receive one or more fluids, a first material adjacent to and in fluid connection with the source, a second material, and a dissolvable volume-metering element positioned between the first material and the second material. The volume-metering element can be configured to provide a fluid connection between the first material and the second material. The volume-metering element can also be configured to at least partially dissolve and break the fluid connection between the first material and second material once a predetermined volume of fluid flows therethrough.
