Blood-oxygen measurement and meter
Abstract
Abstract APPARATUS AND METHOD FOR ELECTRICALLY AND QUICKLY MEASURING AND INDICATING THE AMOUNT OF OXYGEN IN BLOOD. THROUGH THIS PROCESS THE IONIZED OXYGEN IS CONVERTED TO OXYGEN ATOMS IN A BLOOD-SAMPLE SOLUTION. THE TOTAL VALUE OF THE GRADUALLY REDUCING FLOW OF THESE IONS IS DETERMINED IN A CIRCUIT BY CURRENT DIVISION, AMPLIFICATION, AND SUMMATION IN A CAPACITOR. THE FINAL RESULT IS QUICKLY SEEN ON AN INDICATOR, CALIBRATED TO READ IN VOLUME UNITS OF OXYGEN IN A PREDETERMINED AMOUNT OF TESTED BLOOD. ECONOMICALLY DISPOSABLE, QUICKLY REPLACEABLE ELECTRODES ARE POSITIONED IN THE IONIZED SOLUTION. TO PREVENT ADHERENCE OF EFFICIENCYDESTROYING, BLOOD PARTICLES ON THEM THEY ARE VIBRATED BY AN ULTRASONIC GENERATOR.
