Method and apparatus for a fluid sampling device
View Patent ↗A blood analyzer device has a housing with a top section coupled to a bottom section, a driver and a plurality of penetrating members housed in a disposable positionable in the housing. A gripper engages each penetrating member. A manually actuated button advances the disposable to move penetrating members into launch positions. A power is source coupled to the driver. A display is at the housing.
1. A blood analyzer device, comprising: a housing;
a penetrating member driver positioned in the housing; a plurality of penetrating members housed in a disposable positionable in the housing;
a gripper assembly that includes a gripper that engages a penetrating member of the plurality of penetrating members with the driver prior to launch of a penetrating member during a lancing event, an open channel that is positioned over the gripper in the gripper assembly, a gripper shaft assembly including a flag, a non-polymeric rod, a polymeric gripper shaft, a magnet and a stepped gripper portion that captures and retains a penetrating member;
an actuator assembly that includes a gripper track coupled to the gripper assembly, a sensor, and a gripper insertion arm;
a sweeper arm coupled to the gripper assembly, the sweeper arm configured to physically retain the gripper assembly and prevent it from accidentally exiting the housing; and
a power source coupled to a drive assembly and the penetrating member.
