Abstract
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.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
235 words
A combination sterile pad support and lancet comprising a member in the shape of the frustum of a cone containing a hollow cylinder extending along the axis of said cone and coaxial therewith, and one end of said cylinder terminating adjacent to, but spaced from, the base of said cone, the opposite end of said cylinder terminating in the top of the frustum of said cone, said cylinder being of a size and shape adapted frictionally to hold a conventional lancet, said lancet being positioned in said cylinder, said member provided with a centrally positioned recess in the base of said member, the depth of said recess being substantially less than the width of said recess, and absorbent pad in said recess containing an antiseptic fluid, said pad having a shape complementary to said recess and substantially filling said recess, said recess being deep enough to hold a quantity of said antiseptic fluid in addition to that antiseptic fluid which saturates said pad, a removable cover on said base completely covering said pad and adapted to cooperate with said recess to prevent said antiseptic from coming in contact with the atmosphere, said cover being separable from said pad whereby said pad will remain in said recess when said cover is removed from said base, a sharp lancet tip extending from the top of said conically-shaped member and a removable cover on said sharp lancet tip.
Claim 2
Dependent Claim
