Abstract
A blood-collecting device includes a suction device for suctioning and thereby swelling a portion of a patient's skin by decompression so that a movable paracentetic needle can be driven into the swollen skin to puncture the skin. Once the skin has been punctured, the paracentetic needle is withdrawn while suction is maintained on the swollen skin in order to draw a blood sample from the patient.
