1. An apparatus for drawing a sample and analyzing bodily fluids, comprising a handle holding a pneumatic actuator, and a sensor unit that comprises a microneedle attached to an elastic membrane and at least one sensor system, the handle and the sensor unit being detachably connected to each other and the pneumatic actuator exerting pressure on the elastic membrane so that the microneedle pierces the skin and subsequently, as the pressure is reduced, the elastic membrane returns to its original shape and thus produces reduced pressure in the interior of the sensor unit, as a result of which bodily fluid is directed to at least one sensor system and causes a physical or chemical property change of the sensor system.
