The invention relates to a system for the extraction and infusion of a body fluid, in particular a system for the extraction and infusion of blood, having a fluid distribution device with an outer structural element at which several connection ports are formed and an inner structural element which is arranged, at least partially, in a seat in the outer structural element, is displaceable between positions and has a hollow space configured for the intake and discharge of a fluid. The invention also relates to a method for operating a system for the extraction and infusion of a body fluid.

System for removal and infusion of body fluid, and method for its operation

The invention relates to an apparatus and a method for determining an analyte in a fluid. Provided in the device is a stirring zone formed in an optionally microfluidic three-dimensional structure, into which stirring zone a sample of the fluid can be introduced and in which there is a stirring device which can be operated in a contactless manner and is optionally designed as a microstirrer, the stirring device being configured so as to stir the sample of fluid introduced into the stirring zone and being loaded with at least one reagent which reacts with the analyte. The invention also provides a stirring device which can be operated in a contactless manner and is optionally designed as a microstirrer, the stirring device being loaded with the at least one reagent which reacts with the analyte.
