Keyed lancet with generic mounting compatibility
First Claim
1. A lancet for use with a lancing device having a keyed female coupling profile, said lancet comprising a keyed male coupling profile generally matching the keyed female coupling profile of the lancing device, said keyed male coupling profile of said lancet circumscribable within a circle having a predetermined diameter.

Abstract
A lancet having a coupling profile that is compatible with lancet holding features of standard lancing devices, but is keyed for mounting in a non-standard lancing device having a cooperating keyed coupling profile; a lancing device having a keyed lancet coupling for receiving a correspondingly keyed lancet but preventing use of unauthorized lancets; and a method of preventing use of unauthorized lancets with a lancing device.

18. In combination:
-
a lancing device having a first keyed coupling profile comprising a non-circular cross section at at least one point along a length thereof; and
a lancet having a second keyed coupling profile for cooperative engagement within the first keyed coupling profile of said lancet. - View Dependent Claims (19)

20. A method of preventing use of an unauthorized lancet in a non-standard lancing device having a non-cylindrical lancet coupling for engaging an authorized lancet, while permitting use of the authorized lancet in a lancet coupling of a standard lancing device, said method comprising providing the authorized lancet with a non-cylindrical coupling profile that is compatible with the non-cylindrical lancet coupling of the non-standard lancing device and the lancet coupling of the standard lancing device.
