Abstract: A device for assisting the visually impaired to collect blood samples for a glucose testing unit is disclosed. The device includes a finger attachment unit having a shape and size that is complementary to a portion of a human finger. An aperture is disposed along a middle section of the finger attachment unit and is in communication with a collection funnel. The collection funnel and the finger engagement unit are arranged at a substantially perpendicular angle to each other, and the collection unit provides an unobstructed pathway through the aperture.

Abstract: This invention relates generally to a tool for setting grading heights and more particularly to a tool for rapid and efficient measurement of grading heights between adjacent or opposing edges. Briefly stated, the preferred embodiment of the present invention consists of two grading pins spaced apart from each other and inserted into the surface adjacent where grading measurements are desired. Slidably disposed on one of the grading pins is a line casing having a spring loaded retractable string therein with the string having a hook on one end whereby the string is effectively stretched between the two grading pins. Thereafter the string is used as a reference line in order to determine the desired grade height.
