Abstract

Systems and methods for delivering to and/or receiving fluids or other materials, such as blood or interstitial fluid, from subjects, e.g., from the skin. Beading disruptors and/or capillaries may be used for facilitating the transport of fluids from a subject into a device. Beading disruptors may disrupt the “pooling” of bodily fluids such as blood on the surface of the skin and help influence flow in a desired way. A capillary may conduct flow of fluid in the device, e.g., to an inlet of a channel or other flow path that leads to a storage chamber. A vacuum (reduced pressure relative to ambient) may be used to receive fluid into the device, e.g., by using relatively low pressure to draw fluid into the inlet of a channel leading to a storage chamber. The vacuum source may be part of the device.
