    • A lancet device including a housing (12) and a lancet structure (70) having a puncturing element (74). The lancet structure disposed within the housing and adapted for movement between a retaining or pre-actuated position wherein the puncturing element is retained within the housing, and a puncturing position wherein the puncturing element extends through a forward end of the housing. The lancet device includes a drive spring (102) disposed within the housing for biasing the lancet structure toward the puncturing position, and a retaining hub (90) retaining the lancet structure in the retracted position against the bias of the drive spring. The retaining hub includes a pivotal lever (92) in interference engagement with the lancet structure. An actuator (47) within the housing pivots the lever, thereby moving the lancet structure toward the rearward end of the housing to at least partially compress the drive spring, and releasing the lever from interference engagement with the lancet structure.
    • 一种柳叶刀装置,其具有壳体(12)和具有穿刺元件(74)的刺血针​​结构(70)。 所述柳叶刀结构设置在所述壳体内并且适于在保持或预致动位置之间移动,其中所述穿刺元件保持在所述壳体内,以及穿刺位置,其中所述穿刺元件延伸穿过所述壳体的前端。 柳叶刀装置包括设置在壳体内的驱动弹簧(102),用于将刺血针结构朝向穿刺位置偏置;以及保持毂(90),其抵抗驱动弹簧的偏压将刺血针结构保持在缩回位置。 保持毂包括与柳叶刀结构干涉地接合的枢转杆(92)。 壳体内的致动器(47)使杠杆枢转,从而使柳叶刀结构朝向壳体的后端移动,以至少部分地压缩驱动弹簧,并释放杠杆以防止与刺血针结构的干涉接合。
