Protection element Needle-Trap

Label with a Protective Function

Protection element Needle-Trap

Used cannulas and hypodermic needles are a constant source of danger for those working in medical establishments. Schreiner MediPharm, an expert in functional labels for the pharmaceuticals industry has thus brought its Needle-Trap onto the market as an active system for avoiding injury from needles. The hazard potential derives less from the pinprick injury itself and more from the high infection risk through potentially contaminated blood.

Gerresheimer Wilden GmbH, Regensburg, Germany, was commissioned to develop the actual needle protection element. The services provided by this medical technology expert cover the development of the plastic part, construction of the mold and production in a clean room. One challenge encountered in the development of the plastic part was the design of the snap elements. The needle was to snap readily into the small arms of these elements yet was still to be held firmly in place by them. The series production of hundreds of millions of these articles is to take place at the German location of Pfreimd in an ISO Class-8 clean room.

The needle protection device is intended for pharmaceutical companies that fill glass syringes with active ingredient and place labels on the syringes on the packaging line. By slightly modifying the labeling unit, it is possible to apply the needle protection in the same way as a normal label. Existing packaging can also still be used, without any modification, according to Gerresheimer Wilden. When the syringe is used, the needle protection element is first folded out of the way, so that the syringe can be employed in the normal manner. After the syringe has been used, it is pressed down with just one hand on a stable surface. At an angle of approximately 45°, the needle audibly clicks into the protection device where it is held securely, and the syringe can be disposed of without any danger. The FDA has now authorized the Needle-Trap for sale on the US market by means of a Premarket Notification.
