1. Device for the in-vivo measurement of the concentration of an analyte in a body fluid comprising:
- a) a component with a flexible surface, b) means for securing adherence of that surface to the skin, c) a rigid part holding one or more subcutaneously implantable sensors, d) means for positioning the flexible surface relative to the sensors in such a way that in a first position the sensors are concealed by the surface and in a second position implantable parts of the sensors are exposed above the surface, and e) a releasable mechanism that when locked retains the means for positioning at the first position such that the surface deforms to a convex shape and when released permits the surface to move the means for positioning to the second position while inserting the implantable parts of the sensors into the skin.

Abstract
An improved diagnostic analyte monitoring device has immovable, rigid sensors connected stationarily to control and measuring means and a flexible surface adhering to the skin and serving for the subcutaneous implantation of the sensors, actuated by means designed for easy handling. Concentration time profiles of endogenous and exogenous analytes measured with the device are used to improve drug treatment modalities on an individualized basis.
