Abstract
A blood sampling device has a lancet ( ) captive within a housing ( ), to be released from a rearward primed position by pressing a trigger ( ) on the side of the housing. A spring ( ) shoots the lancet ( ) forwards, momentarily to project its tip. The lancet ( ) is initially held by a hooked tongue ( ) that latches behind a transverse web ( ) within the housing, the trigger action dislodging that engagement. The tongue ( ) either springs back after release and so will abut the trigger ( ) or the front of the web ( ) if pushed back in an attempt to re-latch, or it will stay permanently deformed and thus be unable to re-engage the web ( ). Alternatively, the trigger ( ) may slice off the hook ( ), making re-use impossible.
