Claim:
1. An apparatus, comprising: a body assembly, having a proximal end, a proximal portion, a distal portion, and an orifice disposed at the distal portion; a knob cap extending from the proximal end of the body assembly; a guide member having a distal end and a proximal end, wherein a receptacle is located at the distal end of the guide member and the proximal end of the guide member is engaged with the knob cap, wherein the proximal end of the guide member is capable of being retracted to a first armed position or to a second position, which is further in a proximal direction from the first armed position, by pulling the knob cap in the proximal direction, the guide member being disposed in the body assembly for guiding a lancet received in the receptacle; and an ejection blade, fixedly disposed in the body assembly, and contacting the lancet to prevent retraction of the lancet relative to the body assembly when the proximal end of the guide member is being retracted to the second position, thereby ejecting the lancet from the receptacle at the distal end of the guide member through the orifice disposed at the distal portion of the body assembly.
