Abstract: An ear oximeter functioning as a transducer for monitoring blood oxygen saturation and pulse rate comprising an ear clamp having a pair of opposed jaws between which body tissue may be clamped for transillumination by light emitted from one jaw into the clamped tissue. Thermostatically controlled heating means arterializes the transilluminated tissue and light emitter from the tissue is monitored by a photoelectric light-intensity meter for indication of percent oxygen in blood within the arterialized tissue.

Abstract: MEASURING OSMOTIC FRAGILITY OF ERYTHROCYTES FOR DIAGNOSIS OF BLOOD DYSCRASIAS. A BLOOD SAMPLE, DILUTED IN AN ISOTONIC SALINE SOLUTION, IS PLACED IN A TEST TUBE WHICH IN TURN, IS POSITIONED IN APPARATUS FOR MEASURING OSMOTIC FRAGILITY OF ERYTHOCYTES IN THE SAMPLE. IN THE APPARATUS, DISTILLED WATER IS DELIVERED DIRECTLY INTO THE SAMPLE AT A PREDETERMINED CONSTANT RATE WITH CONTINUOUS MIXING TO MAINTAIN EQUILIBRIUM OF TONICITY THROUGHOUT THE SAMPLE. THE SAMPLE IS TRANSILLUMINATED DURING SUCH DILUTION AND LIGHT TRANSMITTANCE THROUGH THE SAMPLE IS PHOTOELECTRICALLY MEASURED AND RECORDED TO INDICATE THE RATE AND PERCENT OF HEMOLYSIS VERSUS TIME OR TONICITY. TONICITIES OF THE SAMPLE AT WHICH HEMOLYSIS STARTS, ENDS AND/OR REACHES OTHER VALUES ARE DETERMINED FROM THE RECORDING FOR INTERPRETATION OF ERYTHROCYTIC OSMOTIC FRAGILITY.

Abstract: Measuring the concentration of bilirubin in unmodified blood serum by defining the light transmission of a microsample of the serum in terms of bilirubin concentration at two preselected specific wavelengths of light wherein the effect of hemoglobin on transmission through the sample is eliminated.
