PORTABLE, SELF-CONTAINED SYSTEM FOR ANALYZING BIOLOGICAL FLUIDS OR THE LIKE

摘要

A completely portable, self-powered system for rapidly and accurately measuring whole blood hematocrit and pH and levels of sodium, potassium, chloride and the other ions in blood and other fluids. The system includes a compact carrying case which contains an aluminum heat block with a glass electrode chamber therein. Individual selective ion electrodes are fitted in the electrode chamber. A reference electrode, a high-impedance electrode switch, a high-impedance solid-state electrometer, a direct readout scale calibrated in pH units and in milliequivalents per liter, and an integral rechargeable power supply are all contained in the carrying case. A heat control unit and a miniature centrifuge along with blood collecting accessories are included in the self-contained system for analyzing biological fluids.
