摘要：
The medical puncturing device includes an actuator, a shield, and a skin puncturing assembly. The actuator and shield are movable relative to one another. The skin-puncturing assembly includes a carrier and a skin-puncturing element. A distal end of the skin puncturing element is adapted for puncturing the skin of a patient. The carrier is movable from a retracted position wherein the distal end of the skin-puncturing element is disposed within the shield to a puncturing position wherein the distal end of the skin-puncturing element is exposed to puncture the skin of a patient. The carrier is maintained in the retracted position by interference engagement between the carrier and shield. A drive spring is provided to move the carrier from the retracted to puncturing positions. A retraction spring is provided to return the carrier to a position wherein the shield encompasses the skin puncturing element.
