Abstract
An analyte test device is constructed as an integrated, single-use, disposable cartridge which can be releasably installed into a compatible analyte test monitor. In use, the device can be used in conjunction with the monitor to lance the skin of a patient to create a blood sample, express the blood sample from the wound site using vacuum forces and calculate the concentration of a particular analyte in the expressed blood sample. In one embodiment, the device includes a base which includes a top surface and a bottom surface. The base is also shaped to define an aperture which extends transversely through its top and bottom surfaces. An electrochemical test sensor is affixed to the base in such a manner so that a vacuum path is at least partially defined between the base and the test sensor, the vacuum path being in fluid communication with the aperture. A cover is affixed to the top surface of the base over the aperture, the cover comprising a flexible dome-shaped member and a lancet coupled to the member, the lancet being orientated such that its longitudinal axis extends at an approximate right angle relative to the longitudinal axis of the test sensor. The bottom surface of the…
