Abstract

The invention relates to a system for withdrawing body fluid from a body part via a withdrawal site located on the surface of the body part, with at least one sensor for detecting at least one variable dependent on the location or state of the withdrawal site, and with an evaluation unit for evaluating the at least one variable detected by the at least one sensor and for triggering a reaction, dependent on the value of the detected variable, in the system for withdrawing body fluid, said reaction serving to prepare the system for puncturing the surface of the body part, and with at least one puncturing device for creating an opening in the body at the withdrawal site. The invention further relates to an integrated analysis system, to a method for configuring a system for withdrawal of body fluid, and to a method for selecting a menu item from a menu for controlling a system for withdrawing body fluid from a body part.
