  • Precision spring lancet
    Patent number: 4203446
    Abstract: A spring lancet holder for creating accurate standardized, reproducible puncture wounds in the skin for medical diagnostic purposes is disclosed in which accuracy and reproducibility is improved by minimizing the recoil transmitted to the lancet holder by actuation of the drive mechanism which pushes the lancet into the skin. In a preferred embodiment, a mass is shown which is caused to move in opposition to the motion of the lancet caused by a striker spring which is mounted between the lancet and the mass.
