1. A single-use skin pricking device comprising:
- a housing defining an opening at one end;
a lancet disposed within the housing, the lancet comprising a cap covering an end of a needle;
biasing means coupled between the housing and the lancet;
a trigger mounted telescopically within said opening of the housing for relative movement therewith, the trigger being releasably coupled to the lancet such that movement of the trigger in a first direction into an interior of the housing moves the lancet along a U-shaped guide track along an inner surface of the housing for guiding movement of the lancet in a direction to compress said biasing means, causes the cap to be removed from the lancet to expose the needle, and then causes release of the lancet from the trigger whereby said biasing means drives the lancet in a second direction substantially opposite to said first direction.
