  • Lancing device having a releasable connector
    Patent number: 6197040
    Abstract: A lancing device has a spring-loaded lancet holder slidably mounted within a housing for carrying a disposable lancet and needle. A slider mounted in a slot in the housing is moved back for cocking the device and, after the lancet is fired, is moved forward to eject the used lancet. A releasable connector reversibly immobilizes the holder while the lancet is being ejected. The releasable connector permits a shortened ejection stroke, which, in turn, permits a shorter slot in the housing.

  • Lancing device causing reduced pain
    Patent number: 6045567
    Abstract: A lancing device has a spring-loaded lancet holder slidably mounted within a housing for carrying a disposable lancet and needle. A knob on the back of the device has forward-extending fingers that stop the lancet holder at an adjustable predetermined point after the device has been fired. The fingers not only control the penetration depth of the needle, but also absorb vibrations and reduce noise to cause less pain to the user.
