METHOD AND APPARATUS FOR BODY FLUID SAMPLING AND ANALYTE SENSING

摘要

The method comprises providing a lancing device comprising a penetrating member ( 68 ) driver having a position sensor ( 74 ) and a processor ( 60 ) that can determine the relative position and velocity of the penetrating member ( 18, 72 ) based on measuring relative position of the penetrating member with respect to time; providing a predetermined velocity control trajectory based on a model of the driver ( 68 ) and a model of tissue to be contacted. Furthermore, a feedforward control is able to maintain penetrating member velocity along the trajectory.
