Abstract:
1. A device for obtaining a body fluid, the device comprising: a lancing element having a tip for puncturing skin of a body part; a test field fluidically connected to the lancing element; and an actuator coupled to the lancing element for moving the lancing element forwardly to penetrate the skin and backwardly to retract from the skin, wherein the actuator drives the lancing element forwardly at a penetration speed less than 0.7 m/s and backwardly at an average retraction speed between 0.001 and 0.01 m/s, and wherein the penetration speed is less than 100 times the average retraction speed, wherein the actuator drives the tip of the lancing element forwardly to a deepest puncture position between 1 and 2 mm below the surface of the skin, and the actuator retracts the tip of the lancing element from the deepest puncture position to the surface of the skin during a retraction period of between 200 ms and 800 ms.
