<P>PROBLEM TO BE SOLVED: To provide a method for producing a lancet device in a cost-effective fashion, which is small in size and designed to carry out a puncture performance so as to soothe the puncture pain at sufficiently high speed; to minimize the generation of noise and impact in puncturing; and to reduce as much as possible what a user has to do before use such as energizing a drive spring. <P>SOLUTION: A lancet is designed to vibrate and move freely up to the reverse position in the puncturing direction, so that the depth of a puncture wound to be caused by the lancet, which is supposed to be within a range set by a control unit, can not be affected by the restriction of a mechanical stopper. <P>COPYRIGHT: (C)2011,JPO&INPIT |
