Title: Blood and interstitial fluid sampling device

Abstract: A device and method for lancing a patient, virtually simultaneously producing and collecting a small fluid sample from a body. The device comprises a blood collection system including a lancing needle, drive mechanism, kneading or vibration mechanism, optional suction system, and sample ejection mechanism. The device is preferably sized to be hand-held in one hand and operable with one hand. The device can optionally contain integral testing or analysis component for receiving the sample and providing testing or analysis indication or readout for the user. A method involves piercing the skin at a rapid rate, kneading the surrounding area by ultrasonic action, piezoelectric or mechanical oscillation to stimulate the blood flow from the wound, drawing the fluid using a pumping system.
