    • It has been discovered that the use of a substantially free-standing voice coil within a lancing device in coordination and combination with a stationary magnet and electronic circuit renders a much improved lancing device. The minimal weight of the free standing voice coil and the attractive forces of the magnet allow the battery-powered electronic circuit to maintain excellent control over the advancement and retraction of a lancet. When the electronic lancing device is initiated by a user, the voltage source within the electronic lancing device provides sufficient current through the voice coil such that the coil and lancet are repulsed from the magnet and propelled into the puncture site. The voltage source subsequently reverses the current through the voice coil to supply sufficient attractive current through the voice coil such that the dwell time of the lancet is minimized and the lancet is retracted from the puncture site and pulled toward the magnet within the housing of the electronic lancing device.
    • 已经发现,与固定磁体和电子电路协调并组合在采血装置内使用基本上独立的音圈使得大大改进的穿刺装置。 独立音圈的最小重量和磁铁的吸引力使得电池供电的电子电路能够对刺血针的前进和缩回保持优异的控制。 当电子穿刺装置由用户启动时,电子穿刺装置内的电压源通过音圈提供足够的电流,使得线圈和刺血针从磁体排斥并推进穿刺部位。 电压源随后反转通过音圈的电流,以通过音圈提供足够的吸引电流,使得柳叶刀的停留时间最小化,并且刺血针从穿刺位置缩回并被拉向电子机壳内的磁体 穿刺装置
