However, when the cover is pressed towards the ele ⁇ rode, only the narrower part of the stepped portion will protrude into the T-shaped opening.

Abstract

Ensemble électrode (20) destiné à un dispositif de destruction d'aiguilles, possédant une première zone dans laquelle on peut faire passer longitudinalement un courant à travers une aiguille, ainsi qu'une seconde zone dans laquelle on élimine tout tronçon d'aiguille subsistant après le passage dudit courant en faisant passer à travers ce tronçon un courant transversal. On décrit deux dispositifs portatifs de destruction d'aiguilles dont l'ensemble électrode (20, 116) est logé dans une cassette jetable (4, 102). Ces cassettes jetables (4, 102) comportent également un compartiment destiné aux déchets qui est séparé de l'ensemble électrode (20, 116) par un portillon (25, 118), lequel s'ouvre lorsque l'on excite l'ensemble électrode (20, 116) afin de permettre aux déchets d'aiguilles de tomber dans le compartiment destiné à cet effet.
