Results in 3 minutes! A new device that can measure the new crown by blowing air is here, and finally there is no need to poke the nose and throat

Several years have passed since the discovery of the new crown pneumonia epidemic. The "cunning" virus has also mutated many times during this period, making it impossible for us to guard against it. Today, human beings are still fighting against the virus, and they have also figured out some ways to deal with it: if you want to stop the spread, you must quickly conduct isolation screening.

To quickly and accurately "hold" the epidemic when it is likely to spread, it is inseparable from rapid testing and obtaining results. Not long ago, the US FDA (Food and Drug Administration) issued an emergency use authorization for the new coronavirus pneumonia (COVID-19) test.

The emergency use authorization was obtained by drug-testing company InspectIR, which has developed a mobile and rapid detection of the new coronavirus, called the "PNY-1000," with results in about three minutes.

The device, developed by InspectIR, is used in a somewhat similar way to common alcohol testers: the person to be tested blows air into the test analyzer through a tube for about 10 seconds, after which the device quickly detects the presence of a breath sample. 5 distinct volatile organic compounds associated with 2019-nCoV infection.

The test is performed by a trained and qualified operator under the supervision of a health care provider licensed or authorized by state law, and results are available in about 3 minutes, faster than the rapid tests that can usually be performed at home, and Accuracy is comparable.

According to the FDA statement, after testing 2,409 people, both symptomatic and asymptomatic, the InspectIR COVID-19 breathalyzer was 91.2 percent accurate for positive samples and 99.3 percent accurate for negative samples. In addition, the accuracy of the detector was also quite stable in the clinical study on the mutant strain of Omicron.

The InspectIR new crown breath detector looks like a small suitcase, but it is actually a gas chromatography mass spectrometry (GC-MS), which can separate and identify chemical mixtures. , it needs to be confirmed by molecular biological detection methods such as PCR (polymerase chain reaction).

However, a negative test result should not be taken lightly, and should be considered in conjunction with the person being tested’s recent exposure, medical history, and clinical signs and symptoms consistent with COVID-19. A negative result does not rule out COVID-19 infection and should not be used as the sole basis for treatment, patient management decisions, or infection control decisions.

The breathalyzers are expected to be produced in about 100 units per week, and each instrument can be used to test approximately 160 samples per day. At this production level and testing capacity, it is expected to increase by approximately 64,000 samples per month.

The FDA's Jeff Shuren, MD, said the authorization is another example of rapid innovation in diagnostic tests for COVID-19. The FDA continues to support the development of COVID-19 disease detection technology with the goal of advancing technologies that can help address the current pandemic and put the United States in a better position for the next public health emergency.

In fact, no matter which country it is, to fight the virus, it is indispensable to speed up the testing.

Nowadays, there are many detection methods for the new coronavirus. Whether it is to centralize the samples to the laboratory or use the kits, most of them need to collect samples through nasal swabs or throat swabs. Although the operation is not difficult, non-professionals It still takes some time to learn, and the time to wait for the results varies from tens of minutes to hours, sometimes even longer.

This tester, which is urgently approved by the FDA, can avoid cross-infection to a certain extent, and cooperate with other test methods to speed up the overall speed of the test. Moreover, it is small and mobile, and the applicable scenarios are more flexible, which is quite helpful in the field of new coronavirus detection.

In the race against the virus, human beings have been working hard.
