Integrated device for diagnostic purposes

A device for obtaining and analyzing a body fluid sample, comprising:

• a housing;
• a lancet body movably disposed in the housing, the lancet body defining a lancet having a tip;
• a motor;
• a mechanical energy store coupled to the motor, wherein energy from the motor is configured to be transferred to and stored by the mechanical energy store, the mechanical energy store being configured to release the stored energy to move the lancet body in a puncturing motion;
• a control guide block which is configured to guide the movement of the lancet;
• and
• an auxiliary functional component coupled to the motor, wherein additional energy from the motor is configured to be transferred to and used by the auxiliary functional component, wherein the energy from the motor is configured to be diverted to the mechanical energy store and the auxiliary functional component.

A method of operating an integrated testing device of the type having a lancet drive with a lancet for puncturing skin and a transport for transporting test elements, the method comprising:

• providing a mechanical energy store configured to drive the lancet drive;
• coupling a motor to the mechanical energy store and to the transport;
• transferring energy from the motor to advance the transport and to the mechanical energy store, the energy transferred to the mechanical energy store being at least partially stored;
• and
• releasing the stored energy of the mechanical energy store through a controlled guide block to the lancet to drive the lancet in a positively guided puncturing movement.
