Lancing system for withdrawing body fluid having a lancing element and a lancing instrument, which includes a lancing drive, by which a lancing movement of a lancing element is driven. The lancing drive comprises a drive source and a transmission having a housing coupling mechanism which includes at least two transmission links, a housing bearing, and a coupling element adapted for coupling a lancing element thereto. A lancing depth limiting stop is positioned in the housing so that a stop surface of the lancing element contacts the lancing depth limiting stop during the forward phase of the lancing movement. The housing coupling mechanism comprises a length compensation device to ensure a distance adaptation of the spacing between the lancing element and a housing bearing of the housing coupling mechanism during contact of the stops and further movement of the lancing drive.

Lancing system for withdrawing a body fluid

The present invention provides an integrated measuring device that includes a blood collection system for collecting blood for diagnostic purposes. The blood collection system comprises an electric motor which provides energy for propelling a lancet. The blood collection system comprises a mechanical energy store in which the electric energy that is converted by the motor is stored in the form of mechanical energy. The use of a mechanical energy store allows the use of known mechanical drive elements. The blood collection system can also be electrically activated and is thus easy to use for the operator. The motor can also be coupled to another system component, such as a test strip or lancet drum, to operate it.
