Patent number: 9724032Abstract: A lancing device and a method for using the lancing device includes a plunger mechanism having a permanent magnet housed therein. The lancing device includes a movable element having at least one attracting object and at least one repelling object. The attracting object attracts the permanent magnet to move the plunger into a retracted position. The repelling object repels the permanent magnet to move the plunger into a lancing position to pierce the skin of a test subject. The use of the permanent magnet in the plunger mechanism reduces or eliminates multiple punctures due to plunger bounce or oscillation that can occur while a body fluid sample is being drawn.Type: GrantFiled: January 24, 2014Date of Patent: August 8, 2017Assignee: Ascensia Diabetes Care Holdings AGInventor: Allen J.
