Abstract
A finger pricking apparatus is disclosed which includes a stop, a guide, a weight and a lancet. The lancet comprises a base, a handle and a needle. The needle is disposed centrally within the base and the handle such that it protrudes from the handle. The lancet is seated in a recess defined by the weight. The weight and lancet are free to reciprocate in the guide. The guide defines a first end and a second end. The stop is seated in the first end of the guide. The stop cooperates with the weight to control depth of puncture of the lancet. In use, the weighted lancet is loaded into the guide. The guide is held between two fingers and inverted. The weighted lancet is thereby caused to travel from the first end to the second end of the guide. When it reaches the first end, the weight contacts the stop, preventing further movement of the lancet. The needle of the lancet protrudes through an opening defined by the stop and pierces a finger, thereby allowing a drop of blood to be drawn.
