Abstract
Lancet system for pain-reduced blood withdrawal comprising an impulse generator which exerts an impulse on a body part in a sequence which is synchronized with the movement of a lancet. Method for the pain-reduced blood withdrawal in which an impulse is exerted on an adjacent body part in a sequence which is synchronized with the generation of an opening in the skin.
Claims17
Lancet system for pain-reduced blood withdrawal comprising,
- a housing with a contact surface which has an exit opening for the tip of a lancet,
- a lancet holder for holding the lancet which can move in the housing along a lancing path,
- a lancet drive for moving the lancet holder along the lancing path,
- an impulse generator which exerts an impulse on a body part in a sequence that is synchronized with the movement of the lancet holder.
