Patent number: 8636675Abstract: The present invention provides a method and a device for piercing a body part and determining whether a sufficient volume of blood has been withdrawn. A lancing element is rapidly inserted into a body part in a forward phase and retracted quickly to a lesser puncturing depth. Subsequently, the lancing element is retracted slower than during the first retraction movement and the distance retracted during the second retraction is shorter than the first retraction movement. During the second retraction movement, body fluid is collected in a collection phase by a capillary structure of the lancing element. Contact between the lancing element and the body fluid is detected after the forward phase at the beginning and the end of a waiting period.Type: GrantFiled: October 8, 2010Date of Patent: January 28, 2014Assignee: Roche Diagnostics Operations, Inc.Inventors: Heinz-Michael Hein, Reto Abt, Stephan Korner, Irio Giuseppe Calasso, Emad Sarofim, Patrick Griss, Rainer Jaeggi
