Date Dec. 30, 1998After removal of a protective cap, the forward end of a barrel (1) of a skin pricker is placed against the skin and the user presses the projecting end of a trigger (6) forwards. As the trigger pivots about a fulcrum (9) of the barrel (1), a thin bridge onto a lancet (2) shears. The lancet is released, and shoots forward as a spring (3) extends, thus projecting a needle tip (4) to prick the skin. This projection is only momentary and the lancet (2), which is captive to the spring (3), is pulled back as the spring (3) reverts to a recovery position where the needle tip is safe inside the barrel. The trigger (6), although broken away from the lancet, remains captive to the barrel by the enlargement (11). The lancet cannot again be operated to eject the needle and the pricker is then intended to be discarded.

Glucose sensor product and related manufacturing and packaging methods

A glucose sensor product is manufactured by a process that maintains the sterility of the glucose sensor while allowing gaseous manufacturing by-products to be vented from the inside of the glucose sensor package. The method begins by placing a glucose sensor assembly into a plastic package tray having a sealing surface surrounding an opening. The method continues by covering the opening with a microbial barrier material such that the microbial barrier material overlies the sealing surface, forming a seal between the sealing surface and the microbial barrier material, resulting in a sealed package tray containing the glucose sensor assembly, and sterilizing the glucose sensor assembly inside the sealed package tray. The microbial barrier material maintains sterility of the glucose sensor assembly while allowing volatile by-products outgassed from the glucose sensor assembly and the plastic package tray to pass therethrough.
