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 and have a volume that is larger than a recess of the fluid transporter that receives fluid from a surface.

The application relates to the technical field of protection devices, and discloses a sputtering-preventing protection device for bone sawing and grinding, which comprises a protection device main body, a tightening belt and a fixing assembly. The protection device is provided with a first transparent plastic film and a second transparent plastic film. In the operation process of sawing a bone or grinding a hip socket, the splashed bone fragments, blood and tissues will first adhere to the surface of the first transparent plastic film. When the surgeon cannot see the internal surgical field through the film, the first transparent plastic film is pulled to drive the bent end of the second transparent plastic film to be unfolded, the adhesive material on the back surface is peeled off, and the first transparent plastic film is separated from the second transparent plastic film. At this time, the first transparent plastic film adhered with the bone fragments, blood or tissues is separated. The method can shield the splashed objects and effectively avoid the obstruction of the vision caused by the adhesion.
