IPC: A61B18/00
Filed: 1999-06-22
Abstract: A blood viscosity measuring system and method that monitors the rising head of a column of fluid (42) representing a living being's blood in-vivo to determine the blood viscosity over a range of shears. The system includes a capillary tube (26), at least a portion of which is located within the vascular system (30) of the being, and a riser tube (44), having a liquid therein coupled to the capillary tube. A sensor (48, 50) and associated microprocessor (52) are provided to determine the change in the height of the liquid in the riser tube (44) at plural points along the length of the tube from which the viscosity is calculated. The system can be utilized to determine the deformability of the red blood cells of a living being's blood and/or the thixotropic properties of a living being's blood. Use of the system enables one to screen a pharmaceutical or other compound on a test subject, such as a living human being or laboratory animal, to determine the likely effect of the pharmaceutical in altering a parameter of the blood, e.g., viscosity, red blood cell deformability, or thixotropic nature, of a living, e.g., human, being to which the pharmaceutical will ultimately be administered.

The attachment component includes a substantially transparent scrim layer (30) of a polymeric film. This scrim layer is un-perforated and includes a pressure sensitive adhesive (36) on its first major surface (32); a heat activated adhesive (40) on its second major surface (34). After the imageable film layer is imaged, the heat activated adhesive may be used to laminate the attachment component to the imageable component to create a finished graphic article. The pressure sensitve adhesive on the attachment component may then be used to attach the graphic article to the transparent substrate (60). When the graphic articles of the present invention are mounted on a transparent substrate, an observer (70) on one side of the substrate may view an image or a message through the substrate, and an observer (72) on the opposite side of the substrate enjoys a substantially unobstructed view through the image and the substrate.
