Patent ID: 8518071

Claim:
A device for the local puncturing of a skin comprising: a puncturing mechanism; a drive mechanism producing a repetitive thrust movement which is for the retraction/extension of the puncturing mechanism; a detection apparatus detecting a parameter indicative of a resistance force acting against the puncturing mechanism; a setting apparatus having multiple present conditions corresponding to different operation modes that are operable when said detection apparatus measures a change in the resistive force, the different operation modes including 1) an increased frequency mode where a frequency of the repetitive thrust movement is increased when said detection apparatus measures an increased resistive force, and 2) a reduced frequency mode where a frequency of the repetitive thrust movement is reduced when said detection apparatus measures an increased resistive force; and a control apparatus coupled to the detection apparatus and the setting apparatus, wherein depending on the preset condition of the setting apparatus, said control apparatus automatically causes the increased frequency of the increased frequency mode or the reduced frequency of the reduced frequency mode when said detection apparatus measures an increased resistive force.
