ABSTRACT:
A skin pricker has a housing (1) for a lancet (5) which, when released from a rearward cocked position, is propelled forwards by a spring momentarily to project its tip (3). During the forward motion a peg (12) within the housing (1) passes along a slot (10) in the lancet and, just before the tip (3) projects, snaps through a neck (11) at the rear end of the slot. If the lancet (5) is then pushed back, the peg (12) cannot re-enter the slot (10): instead it wedges the lancet sideways and, before it can be re-cocked, traps the lancet behind an abutment (13) ensuring that the tip (3) cannot be re-exposed.
