Novel coronavirus COVID-19 marker detector and detection method

Abstract

The invention relates to a novel coronavirus COVID-19 marker detector and a detection method. The detector comprises a laser emitting device, a light angle adjusting device, a beam expander, a gas receiving device, a signal processing device and a PC processing terminal, wherein the gas receiving device is internally provided with a triangular annular ring-down cavity, a temperature controller anda pressure gauge; laser emitted by the laser emitting device vertically enters the beam expander to be processed after passing through the light angle adjusting device, then enters the triangular annular ring-down cavity of the gas receiving device to be measured and is transmitted to the PC processing terminal through the signal processing device. According to the detection method, whether a patient with novel coronal pneumonia is diagnosed by detecting whether the concentrations of ethyl butyrate, butyraldehyde, isopropanol and acetone in respiratory gas are abnormal or not. The optical cavity ring-down spectroscopy technology has the advantages of being high in precision, short in time, low in detection cost, capable of greatly improving the medical diagnosis efficiency, good in economic space, large in research and development value and considerable in development space.

Description

technical field [0001] The present invention relates to the interdisciplinary field of physics and medicine, in particular to a novel coronavirus COVID-19 marker detector and detection method. Background technique [0002] At present, the detection method of the new coronavirus in medicine is mainly through nasopharyngeal swab, chest CT or blood routine examination. The nucleic acid detection of the new coronavirus generally takes 30 minutes to 120 minutes depending on the nucleic acid extraction method, and the nucleic acid amplification time is within 2 hours, and the time for manual operations such as reagent preparation, sample addition, and result analysis is added. An experiment takes 4-5 hours. If the circulation time of samples in the hospital is taken into account, it usually takes 6-8 hours from patient sampling to test results. The vast majority of grassroots hospital laboratories do not have the above-mentioned professionals and equipment and facilities, and wil...

Problems solved by technology

[0003] Most of the thermometers on the market that can be monitored by the public at any time, but only measuring temperature is not reliable enough for the detection of new coronary pneumonia. The common cold, fever and exercise can also cause changes in body temperature, resulting in inaccurate test results and misdiagnosis In addition, studies have shown that 87.9% of patients with new coronary pneumonia have clinical manifestations of fever, and some people do not have such symptoms

Therefore, temperature measurement is not perfect as a detection method.
