Single-use lancet sensor assembly and meter

摘要

A single-use lancet cartridge for inserting into a multi-use lancet driver assembly of a meter housing includes 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 that is a rotated drive wing incorporated within the lancet cartridge and oriented to cooperatively engage with a driver piston of the multi-use lancet driver assembly only one time thereby preventing the lancet from being moved into a piercing orientation a second time.

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 a rotatable drive wing having at least a first drive wing portion directly connected to a lancet body of the lancet and rotatable between a first position and a second position wherein the first position has the first drive wing portion extending laterally from a side of the lancet and wherein the second position has the first drive wing portion failing to extend beyond the side of the lancet, wherein when the first drive wing portion is in the first position the first drive wing portion is presented for cooperative engagement with the driver piston and when in the second position the first drive wing portion is incapable of cooperative engagement with the driver piston.
