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 a hand-held instrument and a disposable sample card. 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. The disposable sample card is a micro-volume conductivity cell precision molded from plastic with built-in stainless steel electrodes. 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 measurement made in the instrument.
