During the NPC and CPPCC this year, west China hospital of sichuan university, dean of wei-ming li hongxing news reporter interview, said the west China hospital experts introduced ─ ─ team led by professor walter hu, through the multidisciplinary cross cooperation, have developed a portable, rapid nucleic acid detection reagent instrument, it can make people to the nucleic acid detection can be at home.
This "Made in Chengdu" COVID-19 integrated nucleic acid test kit was officially unveiled at the "Science and Technology Empowerment Games" event held in Chengdu today (March 24). The reporter saw that the nucleic acid detection box looks like a lighter. How does it work? Field staff conducted a simple demonstration: the staff removed the nasal swab, put it in the test box, removed the card buckle, and gently pressed the sealing cap like a cigarette lighter. After powering on, wait for about 30 minutes. The test results are presented in the form of bright lights on the card box. "With this lighter-sized device, nucleic acid testing can be done at home, which is very convenient and can be easily used by people without a medical background."
"It is also the industry's first 'lighter' rapid nucleic acid self-test product, suitable for all kinds of infectious diseases, anyone anywhere can carry out nucleic acid testing." Staff, nucleic acid detection box of the microfluidic chip technology breakthrough "instrument and reagent" existing in nucleic acids detection with traditional model, integration of the sample preparation, amplification and detection of three steps in a test box the size of a cigarette lighter, with the help of a thermostatic expansion technology after the special craft processing, the reagent for nucleic acid amplification by freeze-drying processing pre-installed in the test kits, Greatly reduce the sample premix and sample adding operation may occur human error, also eliminate the contamination of nucleic acid products. "It is equivalent to providing a whole new PCR laboratory for each sample, with possible cross-contamination and pathogen transmission risks contained within a closed test box." It not only ensures the detection accuracy, but also protects the safety of testing personnel. It can be widely used in home testing, hospital outpatients, primary medical institutions and public places for rapid nucleic acid screening. Along with the test kit, the company also unveiled a portable reading device for COVID-19 nucleic acid tests.
The reader is shaped like a circle, about the size of a fist. The field staff said that this is a Mini handheld reader, the principle is similar to the detection box, after putting the sample, the indicator light quickly discriminated, 30 minutes to complete the test to obtain the results. It is worth mentioning that the reader can be reused. Staff metaphor: "The reader is like a razor, and the sample box is like a razor blade. You only need to put samples in the test, so you can flexibly respond to real-time and accurate detection in the field." At present, the research and development of the two products has been basically completed, and we are applying for the medical device registration certificate with relevant partners.
