Publication number: 20120109176Abstract: Adjustment mechanisms are used in conjunction with integrated lancet test strips to adjust the position of the drive system, engagement system, or the drive coupling in a fixed stroke lancing system to thereby adjust the penetration depth of the lancet. In a variable drive stroke lancing system, the lancet penetration depth is adjusted by changing the stroke length of a drive system. The stroke length of a drive system is adjusted by rotating a cam or sliding a cam in a cam type drive system. In either the fixed or the variable drive stroke lancing system, the test strip and/or guidance foil of the integrated lancet test strip is immobilized while the lancet is actuated.Type: ApplicationFiled: November 3, 2010Publication date: May 3, 2012Inventors: Steven N.
