ABSTRACT:
To enable conventional adapter assemblies used to accurately position a removable biosensor, to be used for measurements in the interior of the skull of small children, the disclosed is a support sleeve which ensures an axial length compensation, taking into account the thinner skull bone thickness, and at the same time ensures accurate alignment of the adapter assembly and the biosensor. The support sleeve also ensures a more even distribution of axial thrust forces when the adapter assembly and the biosensor are positioned. The support sleeve comprises an inwardly extending peripheral flange defining an annular space between the flange and a tubular element slidably inserted in the sleeve. A spring element disposed in the space assures adequate anchorage in the skull bone.
