Abstract
A method for the inspection of a condition, in particular for the detection of defects, of a cannula (or injection needle) mounted on a syringe, which is located under a protective cap, and devices for carrying out such methods. A method includes measuring a magnetic field, in particular a magnetic field distribution, in the vicinity of the cannula. The presence of a ferromagnetic cannula causes a local change in the course of the magnetic field lines. This can be measured and used to determine whether the cannula, as desired, is arranged straight and coaxially to the syringe longitudinal axis, or whether it has a defect, such as being bent, kinked, compressed, broken/severed, oblique to the longitudinal axis of the syringe or eccentric to the longitudinal axis of the syringe.
