An apparatus with a housing (1) containing a first, stationary lower plate electrode (9) and a second, movable upper plate electrode (10), wherein both plate electrodes are electrically conductive, mutually insulated and electrically connected to respective terminals of a battery (7). The second plate electrode (10) is freely movable, spaced apart from the first plate electrode (9) and provided with an opening (17). A syringe needle (16) to be destroyed may be inserted into the opening (17) such that it contacts both plate electrodes (9, 10) and an electric current flows through the needle to melt and thus destroy said needle. The molten metal resulting from the destruction of the needle (16) falls into a collecting compartment (18). An electric current control circuit inhibits operation when the electrodes are dirty. A reliable apparatus guaranteeing the destruction of the needle (16) to provide effective decontamination is thus achieved.

L'appareil selon l'invention comprend, dans un boîtier (1), une première plaque électrode (9) inférieure fixe et une seconde plaque électrode (10) supérieure mobile, toutes deux conductrices de l'électricité, isolées l'une de l'autre et connectées électriquement aux bornes respectives d'un accumulateur (7). La seconde plaque électrode (10) est librement mobile vers et à l'écart de la première plaque électrode (9), et comporte une lumière (17). Une aiguille (16) de seringue à détruire peut être engagée dans la lumière (17) et, par contact entre les deux plaques électrodes (9, 10), est parcourue par un courant électrique qui provoque sa fusion et sa destruction. Le métal fondu résultant de la destruction de l'aiguille (16) s'écoule et tombe dans un compartiment récepteur (18). Un circuit de commande de courant électrique inhibe le fonctionnement en cas de présence d'un encrassement sur les électrodes. On assure ainsi un fonctionnement fiable de l'appareil, qui détruit à coup sûr une aiguille (16) pour assurer une décontamination efficace.
