  • Patent number: 4635633
    Abstract: In order for diabetics to test themselves for stat glucose levels to determine whether or not they should self administer insulin, it is necessary to draw a drop of blood from the diabetic's finger, place the drop of blood on a commercially available blood glucose test media and compare the resulting color of the test strip with a standard chart to determine the blood glucose concentration. This invention is directed to a cheap, disposable, combination sterile pad support and lancet which may be used to disinfect the end of the finger area and then used to stick the finger to draw blood and the sterile pad may also be held on the stick site firmly, thus aiding the blood clotting time after the drop of blood has been placed on the blood glucose test strip.
