The white-body and blue-topped "square box" covering an area of about 5 square meters can receive barcodes and clean test tubes through QR code scanning and registration. The nucleic acid sampling can be completed in as little as 30 seconds.
This is the "black technology" used in the prevention and control of the epidemic in Chengdu.
From sampling warehouses to mobile nucleic acid testing vehicles, from nucleic acid testing reagents to vaccine research and development, there is no lack of Chengdu science and technology in the national fight against the new crown pneumonia epidemic.
The fastest sampling efficiency in 30 seconds is increased by about 90%
"Check the pressure gauge again. Is there any problem with the communication system? This door must be kept closed at all times..." In the open space at the entrance of the emergency department of Chengdu Third People's Hospital, a white-body and blue-topped "square box" is very eye-catching. The building of the guard post is an anti-epidemic black technology-a mobile nucleic acid sampling warehouse.
In the warehouse body, Li Xiang, general manager of Sichuan Shiyang Purification Engineering Co., Ltd., is directing construction personnel to carry out the final commissioning and installation. Soon, this sampling warehouse will be formally "served" and put into epidemic prevention and control work.
Observing the sampling chamber from a close distance, it can be found that the body of this chamber is very "heavy".
"Although it looks very'heavy', the weight of the silo body itself is only about one ton. With the wheels and supporting parts under the silo body, it can be easily moved." Li Xiang introduced that the R&D and design of the silo body was developed by the company and The original intention of Sichuan University was to strengthen the protection of medical staff, create a more comfortable working environment for them, and reduce the chance of cross-infection between residents and medical staff during the sampling process.
The entire warehouse occupies an area of about 5 square meters. At the entrance of the door is a dressing room. The top is equipped with an ultraviolet and alcohol disinfection system. The dressing room and the operation room are isolated by a curtain.
Walking into the operating room, you can see that an air conditioner is installed on one wall, and a digital display is also hung on the adjacent wall, which can display the date, time and indoor temperature.
The two consoles are placed at 90°, one can place electronic equipment such as computers, and the other is close to the window, separated from the outside by two layers of glass, and rubber gloves that can extend outward are set on the window. It is convenient for medical staff to carry out nucleic acid tests on residents.
"Through the positive pressure system inside the warehouse, it is possible to completely ensure that the outside air enters after being filtered, and the carbon dioxide and other gases generated inside are filtered out after being filtered by the'fresh air system', which fully guarantees the safety of medical staff. In theory, medical staff can You don't need to wear protective clothing to work. At the same time, a constant temperature can also allow medical staff to have a relatively comfortable working environment in high temperature, rain and other weather." Li Xiang said.
"The unique design is that when using the sampling chamber for nucleic acid detection, except that the sampling needs to be done manually by medical staff through gloves extending from the inside to the outside, the rest can be done by the residents themselves." Li Xiang introduced, in the past, residents performed nucleic acid in the hospital. The test requires online registration and payment, and then go to the nucleic acid sampling site to register and confirm, and then receive the test tube and barcode for nucleic acid detection. Except for the registration payment, which can be operated by mobile phone, the rest of the process requires manual operation. The entire process takes about a few minutes at the fastest time.
"Considering the improvement of efficiency, we have set up a QR code scanning registration at the window of the sampling warehouse. Residents will receive an electronic barcode after directly scanning the QR code and filling in the information when queuing. When the detection starts, they can directly open the electronic barcode scanning to self-service. Receive the barcode and clean test tube. After sampling, the sample can be directly placed in the recycling bin at the corner of the bin." Li Xiang said that according to theoretical calculations, the entire testing process takes only 30 seconds at the fastest, and the sampling efficiency is increased by about 90%.
At present, mobile sampling warehouses have been put into use in Chengdu No. 1, 2, 3, 5, and 6 People's Hospital one after another, and Mianyang, Luzhou and other cities are also consulting and ordering.
"In the next step, the product will continue to be upgraded. For the elderly and children, how to make them more convenient to complete registration and sampling requires us to explore together with universities, relevant departments and medical institutions." Li Xiang said.
Rush to aid Chengdu forces in the epidemic of science and technology in many places
In addition to the mobile nucleic acid sampling vehicle, there is no shortage of Chengdu science and technology in the national fight against the new crown pneumonia epidemic.
Chengdu Gree Xinhui Medical Equipment Co., Ltd. is one of them.
In September last year, Chengdu Gree Xinhui launched the country's first new energy mobile P2+ nucleic acid testing vehicle to actively support epidemic prevention and control.
Recently, Gree New Energy Mobile P2+ nucleic acid testing vehicle also rushed to Nanjing for the first time to carry out first-line nucleic acid testing. This is also after the product has served Chengdu, Luoyang, Zhuhai, Changsha, Heihe, Hekou, Guangzhou and other places, it once again used technological innovation to help the epidemic Prevention and control.
In this testing vehicle, the laboratory information management system, high-throughput automated sample preparation system and air purification system are integrated, and it is equipped with high-precision testing equipment and digital processing technology. Increase the analysis area, sterilization area, buffer area, dressing area and other areas to realize automatic extraction, automatic detection and automatic management of samples, effectively reducing the possibility of personnel contact with pathogens, and rapid inspection and testing of collected samples, which is safe, reliable, fast and flexible ,high degree of automation.
The "black technology" forces made in Chengdu are still supporting the global war epidemic on a larger scale and at a broader level.
In terms of detection kits, the fully automatic nucleic acid analyzer and the supporting new coronavirus 2019-nCoV nucleic acid detection kit (fully integrated disc chip method) developed by Chengdu Boao Jingxin Biotechnology Co., Ltd. were approved by the State Food and Drug Administration as a medical device Registration has been widely used in nucleic acid detection in Zhuhai, Lanzhou, Wuhan and other places.
The three-target nucleic acid diagnostic reagent of Mike Biology Co., Ltd. played a full role in the environmental detection and virus traceability of the new coronavirus. It was first applied in Chengdu, Shijiazhuang, Yunnan, Heilongjiang, Guangzhou and other places. At the same time, it has obtained the European Union CE, The US FDA and other certifications have been sold to 89 countries and regions around the world.
In terms of vaccine research and development, the recombinant new coronavirus pneumonia vaccine developed by the State Key Laboratory of Biological Therapy of Sichuan University is currently undergoing Phase III clinical trials and is applying for marketing.
