| titleOfInvention | FLOW SPEED DETECTOR AND / OR GAS CONCENTRATION. |
| abstract | The present invention describes a gas flow rate and / or gas concentration detector suitable for measuring the oxygen concentration and gas flow rate that is delivered to a patient for medical purposes. Two piezoelectric transducers are mounted on a printed circuit board that are interconnected by means of an elongated coiled tube. Gas is flowed around one of the transducers, through the tube, and around the other transducer. Periodically one of the transducers is activated with a short single pulse to transmit a conical wave through the gas to the other transducer. The travel time for the conical wave is measured. The two transducers are used alternatively as transmitters and receivers, in such a way that the wave travel time is measured with and against the direction of the gas flow. A transmitter is located in the center of the coiled tube to measure the gas temperature, from the measured times, the measured temperature and the stored formulas, a microprocessor calculates the oxygen concentration and / or flow rate for the gas. The detector can also be used to measure other components of a gas mixture. |
