Systems and methods for collecting fluid from a subject
First Claim
1. A device for receiving bodily fluid from a subject, the device comprising:
- a fluid transporter including a flow activator having one or more needles, the fluid transporter further including an opening into the device and a recess extending upwardly from the opening such that the opening is at a lowermost portion of the recess, the opening and the recess being in fluid communication, wherein the opening is arranged to receive bodily fluid from a subject and the recess has a substantially vertical inner surface defining an internal width of the recess;
a channel having an inlet in fluid communication with the fluid transporter; and
a beading disruptor located with respect to the fluid transporter to interact with fluid entering the opening of the fluid transporter and influence flow of the fluid to the inlet, the beading disruptor comprising a plurality of protrusions cantilevered from the substantially vertical inner surface of the recess into the recess,wherein the protrusions are spaced apart from one another,and wherein the protrusions are spaced apart from and positioned above the opening into the device such that a portion of the substantially vertical inner surface of the recess is positioned below the protrusions.

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.
