The present invention relates to a personal portable painless lancing device and a blood glucose meter using the same, which can lance at the minimum without any pain and use it to measure the blood glucose. The minimum painless lancing device using an Er:AG laser suggested by the present invention, comprises an Er:YAG laser beam-generating section in which the laser beam is generated to punch skin and radiated in a single direction an adapter installed at the front end of the Er:YAG laser beam- generating section so that the laser beam can be locally concentrated on a skin punch portion a skin adhesion cap installed at the front end of the adapter so that it can be easily detached, and can reduce the contamination of the Er:YAG laser beam-generating section, which is produced at the time of the lancing, and the danger due to the reuse of it among the patients of lancing and a case for accommodating the Er:YAG laser beam-generating section and the adapter therein. In this regard, the blood glucose meter suggested by the present invention comprises a minimum painless lancing device with the structure as described above, a connector for inserting a blood glucose sensor strip, a blood glucose measuring circuit, and means for displaying the measure blood glucose value.Linvention concerne un dispositif dincision portatif personnel, sans douleur, et un glycomètre comprenant ce dispositif, permettant de pratiquer une incision minimale sans douleur et de mesurer la glycémie. Ce dispositif dincision minimale sans douleur utilisant un laser Er:YAG comprend une section génératrice de faisceau laser Er:YAG, dans laquelle le faisceau laser servant à inciser la peau est généré et émis dans une seule direction, un adaptateur monté à lextrémité avant de la section génératrice de faisceau laser Er:YAG, permettant de concentrer localement le faisceau laser sur une section de perforation de la peau, un embout dadhérence cutanée monté à lextrémité avant de ladaptateur dune manière perm
