Abstract

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.

Claims

1. A blood analyzer device, comprising:

a housing with a top section coupled to a bottom section;

a driver;
