A reagent test strip for measuring an analyte concentration in a biological fluid has a spreading mesh sandwiched between a support and a reagent matrix as discussed by the authors, which is covered by the mesh.Abstract:
A reagent test strip for measuring an analyte concentration in a biological fluid has a spreading mesh sandwiched between a support and a reagent matrix. The support has a through hole that is covered by the mesh. In use, a sample of the fluid is applied through the hole in the support to the spreading mesh. The sample then passes through the mesh to the matrix, which contains a reagent that indicates the analyte concentration by causing a corresponding change in reflectance at its free surface. Optionally, an adhesive layer attaches the mesh, and optionally the matrix as well, to the support.read more

TL;DR: In this article, a method and apparatus for obtaining a sample of blood from a patient for subsequent diagnostic tests, e.g., glucose monitoring, is described. But the method comprises the steps of: (a) forming an unobstructed opening in the area of the skin from which the sample is to be extracted; and (b) extracting the sample of the blood from the unobstructed open in the skin, with the aid of a vacuum and a stretching of skin.
