Abstract

This invention is directed to a cheap, disposable combination sterile pad support and lancet which may be used in connection with drawing blood for various tests including stat glucose levels for diabetics cholesterol determinations and others. It includes means for reinserting the lancet in the support following usage so that no individual will come in contact with the pointed end of the lancet. The sterile pad may be used to disinfect the end of the finger and then the lancet may be used to stick the finger to draw blood and the sterile pad may also be used on the stick site firmly thus aiding the blood clotting time after the drop of blood has been removed.

Claims

1. A combination sterile pad support and lancet comprising:

a member provided with a base and containing a hollow cylinder, one end of said cylinder being closed and terminating adjacent to said base, the opposite end of said cylinder being open and terminating in the end of said member opposite to said base,

a lancet, said cylinder being of a size and shape adapted frictionally to hold said lancet, said lancet being positioned in said cylinder,

said lancet having a sharp pointed end on one end thereof and a removable cover on said sharp pointed end,

said one end of said lancet extending out of said cylinder a distance so that said lancet may be readily pulled out of said cylinder,

said hollow cylinder containing means for gripping said lancet when said lancet is reinserted into said cylinder with said sharp pointed end extending into said cylinder, after said cover on said sharp pointed end has been removed,

said member being provided with a recess in the base of said member,

an absorbent pad in said recess containing an antiseptic fluid,

a removable cover on said base completely covering said pad and adapted to cooperate with said recess to prevent said antiseptic fluid 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.

2. The combination sterile pad support and lancet of claim 1 wherein said member is in the shape of the frustum of a cone with the base of the cone being coextensive with the base of the member.

3. The combination sterile pad support and lancet of claim 2 wherein said conically-shaped member is provided with indented finger engaging portions on its outer surface.

4. The combination sterile pad support and lancet of claim 1 wherein said means for gripping said lancet when said lancet is reinserted into said cylinder consists of an annular ring extending into the interior of said cylinder.

5. The combination sterile pad support and lancet of claim 1 wherein said cylinder is provided at its closed end with a recess of a size adapted to receive the sharp pointed end of said lancet when said lancet is reinserted into said cylinder.

6. The combination sterile pad support and lancet of claim 5 comprising a lancet of a length so that when it is reinserted into said cylinder with said sharp pointed end of said lancet extending into said cylinder, the end of said lancet opposite the pointed end will be flush with the end of said member opposite said base.
