Even more precision during the pre-filled syringe inspection!

The HEUFT Syringer now also detects inconspicuous needle hooks using innovative additional optics.

Almost as hard to find as a needle in a haystack: the micrometre deformations on the tip of the cannula are hardly visible to the naked eye. Nevertheless they represent a not inconsiderable risk to the functionality and safety of pre-filled syringes – and therefore also to the health and well-being of the patient receiving the injection. That is why it is essential that such needle hooks are detected during the packaging process and the syringes in question removed in good time. This is now achieved reliably with the further developed HEUFT Syringer.

For this the compact detection unit can be upgraded with innovative additional optics for detecting needle hooks which extends the unique pulsed X-ray technology for a careful and precise pre-filled syringe inspection optimally. An intelligent colour sensor camera, developed by HEUFT, examines the tiny needle tips from above even before the protective covers have been added. The special light dispersion of the adaptive LED lighting used for this purpose ensures that even the smallest shape faults become visible.

Pulsed X-rays for the cannula and protective cap inspection

The already thoroughly tried and tested X-ray detection identifies numerous other safety and integrity defects of pre-filled syringes after the caps have been applied with unrivalled low radiation – such as soft and rigid needle shields (SNS / RNS) pierced by the hypodermic needle, bent and deformed cannulas or incorrectly assembled, unsafe to use, defective or leaking luer lock screw adapters and tamper evident closures of disposable syringes.

The further developed HEUFT Syringer which fulfils fundamental FDA, GMP, GAMP5 and 21 CFR Part 11 requirements consistently is extremely compact and very easy to integrate into packaging machines for such pre-filled injection instruments. And faults and defects become visible with the new additional optics which are almost as difficult to find as the proverbial needle in a haystack.
