    • A skin pricker has a barrel (1, 11) in which a hammer (2, 29) released by a trigger mechanism (32, 34) can be shot forwards by a compressed spring (3, 38) to impact on a lancet (24) and momentarily project its tip. The rear end of the spring acts against a barrier (4, 39) adjustable axially of the barrel, so that the spring can be more or less compressed before release, causing the hammer to act with greater or lesser force on the lancet. The barrier (4, 39) may have projections (6, 8, 42) that engage in skew slots (7, 9, 43) in the barrel, so that rotation of the barrier axially adjusts it. A sleeve (44) over the rear part of the barrel instrumental in priming the device may co-operate with the projections and be rotatable to set the desired spring force.
    • 皮刺具有桶(1,11),其中由触发机构(32,34)释放的锤(2,29)能够通过压缩弹簧(3,38)向前射出以撞击刺血针(24 )并暂时投射其小费。 弹簧的后端作用在一个可调整的筒体轴向的挡板(4,39)上,以便弹簧在释放之前可以或多或少地被压缩,从而使得锤体以更大或更小的力作用在刺血针上。 屏障(4,39)可以具有接合在桶中的倾斜狭槽(7,9,43)中的突起(6,8,42),使得屏障的旋转轴向调整它。 在用于装填装置的机筒后部上方的套筒(44)可以与突起协作并且可旋转以设定期望的弹簧力。
