Abstract
A sensor for use in a sensor dispensing instrument so that fluids can be tested when the sensor is ejected from within a sensor cavity of a sensor pack sealed by a foil. The sensor has a generally flat, rectangular shape, is formed by a base and a lid, and has perpendicularly extending longitudinal and transverse axes. A notch in a rear end of the sensor is engaged by a knife blade within the sensor dispensing instrument as the sensor is being ejected through the foil. A front testing edge of the lid overhangs a front testing edge of the base of the sensor. One side edge of the sensor adjacent the front edges of the base and lid is beveled at about a 25.degree. angle. The front base edge extends from the beveled side portion across the entire remaining width of the sensor at an angle of approximately 10.degree. with respect to the transverse axis. A portion of the front lid edge extends from the beveled side portion across a significant portion of the width of the sensor at an angle of about 15.degree. with respect to the transverse axis. The other portion of the front lid edge extends at an angle of about 25.degree. with respect to the transverse axis so that a relatively pointed …
