Patent number: 10753923Abstract: A test meter for analyzing a body fluid sample applied to a test strip includes an outer housing having an opening, an actuator, and a cartridge positioned adjacent the outer housing. The cartridge further includes a dispensing member connected to the actuator, a plurality of stacked test strips biased toward the dispensing member, and a cartridge outer housing that is adjacent at least a portion of the dispensing member. Each time the actuator is actuated, the dispensing member is rotated to cause movement of one test strip from the plurality of stacked test strips through the opening, and another test strip is biased toward the dispensing member.Type: GrantFiled: May 7, 2019Date of Patent: August 25, 2020Assignee: Ascensia Diabetes Care Holdings AGInventors: Eugene R. Prais, Michael A. Botta, Narasinha Parasnis, Serban Peteu, John Creaven, Simin Yao
