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 and is formed by a base and a lid. The sensor has a perpendicularly extending longitudinal and transverse axes. A rear end of the sensor has a notch that is engaged by a knife blade within the sensor dispensing instrument as the sensor is being ejected through the foil from the sensor cavity. 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° 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° with respect to the transverse axis. A first major 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° with respect to the transverse axis of the sensor. The other portion of the front lid edge extends at an angle of about 25° with respect to the transverse axis of the sensor so that a relatively pointed tip at the side edge opposite from the beveled side portion is formed to pierce the foil as the sensor is being ejected from the cavity.
