Claim:
A re-use prevention mechanism for an apparatus having a reusable part and a single-use disposable part connectable to the reusable part, the re-use prevention mechanism comprising: a blocking portion disposed, during the single-use, between the connected disposable part and the reusable part, the blocking portion being adapted to engage a recess in the reusable part to rotationally lock the disposable part to the reusable part; and an actuating member operable between the blocking portion and one of the disposable part and the reusable part for moving the blocking portion into a blocking position upon disconnection of the disposable part from the reusable part; wherein, in the blocking position, the blocking portion engages an abutment surface on one of the disposable part and the reusable part if a user attempts to reconnect the disposable part to the reusable part and thereby prevents re-connection of the disposable part to the reusable part.
