Patent ID: 7988845

Claim:
A device to determine the concentration of glucose in blood from a patient, comprising: a piercing member adapted to pierce and retract from a site on the patient to cause blood to flow therefrom; a sensor adapted to receive the blood flowing from the site to generate an electrical signal indicative of the concentration of glucose in the blood, the sensor having a proximal end into which the blood enters, the sensor and the piercing member forming an integrated unit, the piercing member facing in the same direction as the proximal end of the sensor and being movable in a parallel manner relative to the sensor, the sensor comprising a first non-conductive substrate and a second non-conductive substrate between which is disposed a sample receiving area having a volume of less than about 1 μl and a working electrode with a glucose-responsive enzyme in communication with the sample receiving area; and a glucose monitor operatively connected to the sensor and adapted to measure the signal generated by the sensor.
