Abstract
Methods and apparatus are provided for manufacturing an analyte detecting device. In one embodiment, the apparatus comprises a housing; a penetrating member driver; a cartridge containing a plurality of penetrating members; a display on the cartridge; a linear slider on the housing, the slider coupled to a rod; and the rod moving with the slider, the rod having at least one roller. The device uses the linear motion of the slider to rotate the cartridge, punch open a new cavity and load a new penetrating member.
