| Zusammenfassung: | The device has a pierce element drive (8), alternating current voltage source (9), an electric measuring unit (10) and an evaluation unit (13). The source of alternating voltage is equipped in such a manner that the alternating voltage signal has a rectangular rising edge. The rising edge of the alternating voltage has amplitude of 10 milli-volts to 200 milli-volts and is a square wave voltage. Independent claims are included for the following: (1) piercing system (2) piercing element (3) a method for the determination of the necessary depth of a piercing element for extraction of body fluid from animals or humans. |
