Lancet sensor assembly and meter
First Claim
1. A lancet system comprising:
- a lancet assembly comprising;
an elongated carrier having a lancet member recess, an open end, a closed end, and a first elongated side opening; and
a lancet member having a lancet body, a lance extending from a first lancet body end, a sinuous portion that is non-compressible when initially disposed within said elongated carrier, said sinuous portion extending from a second lancet body end to a sinuous distal end, and a first drive wing fixedly attached to and extending outwardly from a first side of said lancet body, said lancet being disposed within said lancet member recess wherein said first drive wing extends through said first elongated side opening and is positioned within said first elongated side opening wherein said elongated side opening and said first drive wing prevents said sinuous portion from being compressed when said first drive wing is in an initial position, said lancet body and said drive wing being slidingly engagable between a retracted position and an extended position wherein said distal end of said sinuous portion is anchored by said elongated carrier adjacent said closed end.

Abstract
A blood glucose measuring system includes a lancet assembly and a meter for use with the lancet assembly. The lancet assembly has a lancet member with a lance, a lancet body having a drive wing extending outwardly from a side, and a sinuous portion, and an elongated carrier having a lancet member recess to contain the lancet member. The elongated carrier has an open end, a closed end, a side elongated opening for receiving the drive wing therethrough, and an anchoring member operatively connected to the end of the sinuous portion. The meter includes a measuring circuit, a lancet trigger, and a lancet driver where the lancet driver includes a driver piston engageable with the lancet trigger and a charging member that operatively engages with the driver piston to move the driver piston into an armed position and to stop the driver piston when released from the armed position.
