Liquid Conductivity Measuring System and Sample Cards Therefor Abstract A system for measuring a parameter of a liquid sample, such as the hematocrit and an approximation of hemoglobin for a blood sample. The system basically comprises an instrument and a disposable sample card. The instrument is a hand-held, battery-operated device used for the fast and simple measurement of a parameter such as blood conductivity. The instrument accepts the disposable sample card, which is used for the one-time conveyance and application of a liquid sample, such as blood, to the instrument. The instrument has provision for digital displays for readouts. There are no exter- nal switches on the instrument, and power is automati- cally applied when the disposable sample card is inserted into the instrument. The disposable sample card is a micro-volume conductivity cell precision molded from plastic with built-in stainless steel electrodes. The sample card comprises a planar base portion on which is defined a capillary tube. First and second electrodes are disposed within the capillary tube in a spaced rela- tionship and define a volume within the capillary tube. This volume constitutes a conductivity cell. The instrument basically comprises an electronic portion for processing data obtained from the liquid sample on the sample card, a front-end mechanism for positioning the sample card within the instrument, and a digital display for displaying in eye-readable form the results of a parameter measure- ment made in the instrument.
