After a needle is received in a loading position, the needle carriage (210) is rotated downwardly to a cutoff position. At the cutoff position, two opposing contact blades (220, 230) pinch the needle, which electrically connects the positive and negative terminals of a battery. Current flows through the contact blades (220, 230) and the needle, thereby melting the needle. A slight further rotation of the needle carriage (210) causes the contact blades (220, 230) to shear the needle. The sheared portion of the needle then falls into a waste compartment. When the syringe is removed from the needle carriage (210), the needle carriage (210) rotates upwardly and returns to the loading position. Torsion spring (236) provides constant pressure against a contact blade (230) to maintain the needle carriage (210) in the loading position in the absence of any downward pressure.
Après avoir placé l'aiguille sur le support d'aiguille (210) en position de chargement, on tourne le support vers le bas pour le mettre en position de découpage. Dans cette position, deux lames de contact opposées (220, 230) pincent l'aiguille, qui relie électriquement les bornes positive et négative d'un accumulateur. Le courant traverse les lames (220, 230) et l'aiguille, et fait fondre cette dernière. Si l'on fait tourner un peu plus le support d'aiguille (210), les lames cisaillent l'aiguille, dont la partie cisaillée tombe dans un compartiment à déchets. Quand on enlève la seringue du support d'aiguilles (210), celui-ci tourne vers le haut et revient en position de chargement. Un ressort de torsion (236) applique une pression constante sur une lame de contact (230), de façon à maintenir le support d'aiguille (210) dans la position de chargement en l'absence de toute pression vers le bas.
