Abstract
Abstract A device for destructing needles and syringes includes a base housing (20) and an upper closure body (22). One side of the housing (20) is open to slidably receive a receptacle (21) to receive severed needles and associated parts. The body (22) includes a rotary die member (32,33) mounted therein for severing the needles and syringes. The receptacle (21) is automatically locked in a closed position upon withdrawal from the base housing (20).
