An improved diagnostic analyte monitoring device has partially retractable hollow guide needles for the intradermal placement of diagnostic elements fixedly connected to measuring means within this device obviating the need to remove the guide needle and to connect the diagnostic elements to measuring means after placement into the skin. A flexible surface adhering to the skin serves for the subcutaneous implantation of the diagnostic elements within the guide needles and partial retraction of the guide needles exposes the active surface to body fluid, actuated by means designed for easy handling and safe operation. Concentration-time profiles of endogenous and exogenous analytes measured with the device are used to improve drug treatment modalities on an individualized basis.
A method for exposing an active surface of a diagnostic element to a body fluid for the measurement of a concentration of an analyte comprising a hollow guide needle for penetrating through a skin of a patient and housing the active surface, and connection lines to a measuring means of the diagnostic element, after insertion of the hollow guide needle, the hollow guide needle is only partially retracted, thereby exposing the active surface at a tip of the diagnostic element to the body fluid, without interfering with connections lines between the active surface, and the measuring means of the diagnostic element.
