<p>A system comprising a disposable device (10) and hand held reader (150) can perform a variety of electrochemical measurements on blood or other fluids. In operation, a fluid sample is drawn into the disposable device through an orifice (108) by capillary action. The orifice is sealed off and the disposable device is inserted into the reader. The reader which controls the test sequence and flow of fluid causes a calibrant pouch (60) located inside the device to be pierced, releasing the calibrant fluid to flow across the sensor arrays (66) to perform calibration. Next an air bladder located in the device is depressed, forcing the sample across the sensors where the measurements are performed and read by the reader (150) which performs the calibrations. Once the measurements are made, the device can be withdrawn from the reader (150) and discarded.</p> |
