Single use lancet sensor assembly and meter
First Claim
1. A single-use lancet cartridge for inserting into a multi-use lancet driver assembly, the single-use lancet cartridge comprising:
- an elongated lancet housing with an open end;
a lancet within the lancet housing and movable between a retracted and resting orientation to a piercing orientation through the open end; and
a re-use prevention component incorporated within the lancet cartridge and oriented to cooperatively engage with a driver piston of the multi-use lancet driver assembly external to the lancet cartridge only one time thereby preventing the lancet from being moved into a piercing orientation a second time, the re-use prevention component being an elongated cocking tab, the elongated cocking tab having a first tab end and a second tab end wherein the first tab end has a piston flange with a driver piston engageable surface and the second tab end has a needle cap interlocking mechanism, the piston flange extending laterally and downwardly from a first side edge of the elongated cocking tab.
