4 results about "Blood or Tissue" patented technology

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.

The present invention relates to a sensor head (10) for measuring the concentration of an analyte in the blood or tissue of an animal or a human, which analyte passively diffused through the skin (2) of said animal or human (P), particularly a premature infant, comprising: a first membrane (30) having a first permeability with respect to the analyte, wherein the first membrane (30) comprises a first contact surface (30a) configured to contact the skin (2) to receive said analyte, a second membrane (31) having a second permeability with respect to the analyte, wherein the second membrane (31) comprises a second contact surface (31a) configured to contact said skin (2) to receive said analyte, and wherein the first permeability differs from the second permeability, wherein the first contact surface (30a) is arranged besides the second contact surface (31a), wherein the first and the second contact surface (30a, 31a) are interleaved.

The invention relates to a fluorescent RNA (Ribonucleic Acid) functionalized hydrogel kit, a preparation method and a method for detecting colorectal cancer miRNA-126, solves the technical problem of how to detect miRNA-126 in blood or tissue samples and is suitable for portable detection, and fluorescent RNA functionalized hydrogel is prepared from methacrylic acid hyaluronic acid, an acryloyl-modified fluorescent RNA aptamer and N, N-dimethylformamide. The fluorescent RNA aptamer is obtained by crosslinking the fluorescent RNA aptamer and N, N '-methylene bisacrylamide, and the covalent crosslinking between the fluorescent RNA aptamer and the hydrogel can prevent the RNA aptamer from being released into the external environment, so that the stability and the anti-interference capability of the hydrogel kit are improved.
