Race with the epidemic, Yantai high-tech enterprises, colleges and universities in tobacco to make scientific research, a number of technological achievements to accelerate research and development applications.
Virus detection time is expected to be as low as 1 hour
Testing is a key part of the diagnosis of new coronary pneumonia patients. For conventional detection methods, it takes about 3 hours for a single sample.
A few days ago, relying on Yantai City Key Laboratory of Animal Pathogenic Microbiology and Immunology, Ludong University School of Life Sciences began "new coronavirus (2019-nCoV) epidemic aerosol detection and environmental control technology research and development", this research and development results are expected to make the new coronavirus detection time limit as low as 1 hour.
"In the early stage, we used nanomaterials, isothermal amplification technology, virus aerosol sampling and evaluation technology, etc., to carry out the establishment of a variety of pathogenic microorganism detection methods including coronavirus and environmental disinfection research, and accumulated a large amount of basic data and research results." Zhang Xingxiao, deputy dean of the School of Life Sciences at Ludong University, said, "The college has done a lot of tests around other viruses, and the compliance rate has reached 93%, but this time the test for the new coronavirus is still under development."
"On February 9, we received the R & D task, and the R & D team of more than 10 people immediately entered the wartime state. Preliminary results have been achieved in 4 days. Today we will conduct laboratory testing. If successful, we will send it to the Municipal Center for Disease Control and Prevention for further testing." Zhang Xingxiao said that this time, a fast and simple detection kit was assembled by establishing a technical specification for virus sampling in the air and developing a new method for loop-mediated isothermal amplification combined with nucleic acid immunochromatography. The detection time limit for a single sample was as low as 1 hour, which was about 3 hours compared with the conventional detection method, thus greatly shortening the detection time.
After the virus is spread through droplets, space disinfection is particularly important. Junxiu Biology is a high-tech enterprise specializing in the research and development and production of medical supplies. Its new antibacterial, antiviral and epidemic prevention products have been approved. Recently, it is stepping up equipment debugging and arranging production.
Jiang Hong, deputy general manager of Shandong Junxiu Biotechnology Co., Ltd., said that the new antibacterial and antiviral protective solution is quick-acting and can kill pathogens in a short time, kill bacteria in 10 seconds, kill mold in 30 seconds, and kill viruses within 5 minutes. The effective rate is 99.99.
Intelligent screening of close contacts identifies how to accurately screen out abnormal persons and close contacts in crowded places such as stations and docks?
Shandong Henghao Information Technology Co., Ltd. emergency research "global population body temperature screening and path tracking system", can realize the rapid screening of all-weather population body temperature, and the use of image fusion, body recognition, cross-border tracking and other technologies, to achieve abnormal personnel path tracking, automatic identification of close contact personnel.
"The system also has a fusion command and dispatch function, which can release the information of abnormal personnel and close contacts to the front line for timely prevention and control, greatly reducing the possibility of cross-infection and doubling the efficiency of epidemic prevention and control." Jiang Xiao, technical director of Shandong Henghao Information Technology Co., Ltd., said that with the strong support of the Municipal Science and Technology Bureau, the "Global Population Temperature Screening and Path Tracking System" has won a special project for the prevention and control of novel coronavirus infection in 2020. The company is conducting urgent research and development. The research and development cycle has been adjusted from one year to 4-5 months, firmly winning the epidemic.
The key technology research and application project of medical ultra-low resistance return air device independently developed by Yantai Baoyuan Purification Co., Ltd. is currently being accelerated.
"During SARS in 2003, we urgently supplied various air filters and chemical filters to Beijing Xiaotangshan Hospital and others." Yu Ziqiang, general manager of Yantai Baoyuan Purification Co., Ltd., said, "During the SARS period, studies have found that the return air outlet of the hospital's air conditioning system is replaced with a medium-efficiency filter to prevent germs from entering the air conditioning system from the return air outlet, which can solve the air supply. Safety issues, ensure the normal use of the air conditioning system, and provide a good environment for medical staff."
Based on this, Baoyuan Purification independently developed a medical ultra-low resistance return air purification device, which has the advantages of ultra-low resistance, high efficiency and low energy consumption. "A number of hospitals have come to inquire for purchase urgently. At present, our emergency supply of ultra-low resistance return air filter device has provided products for 11 hospital renovation projects." Yu Ziqiang said.
Non-contact temperature detection takes only 1 second
How to achieve rapid and accurate temperature detection of people? The non-contact temperature detection system, a new type of temperature measurement method independently developed by Shandong Hanxin Technology Co., Ltd., is now officially launched to achieve ultra-high precision temperature detection of infrared thermal imaging system "black body", to quickly measure pedestrians, to detect abnormal body temperature and alarm in time, and is being applied to major office buildings in Yantai.
At more than 10 a.m. on the 9th, several technicians from Hanxin Technology Co., Ltd. were busy debugging temperature measuring equipment on the 11th floor of Block B, Blue Ocean International Software Park, Yantai High-tech Zone. With the opening of the temperature measurement system, the reporter saw that the picture on the computer screen was divided into two parts, the left part showed the monitoring real-time picture, and the right part showed the thermal imaging picture. Whenever a person passes through the monitoring area, his body temperature can be displayed on the computer screen in real time, and the whole temperature measurement process takes less than 1 second.
"The system consists of a human body temperature measurement thermal imaging camera, a high-precision blackbody, and a computer terminal. It is very convenient to use. The thermal imaging equipment can simultaneously detect and measure the temperature of multiple people's faces. The detection results are displayed in real time around the clock, and the detection accuracy is controlled at ± 0.3 ℃." Ge Jian, technical director of Hanxin Technology's non-contact body temperature detection project team, told reporters that once the system detects abnormal body temperature, the thermal imaging camera will start a flash alarm and issue a voice prompt to help the detection point staff intercept the abnormal body temperature.
As a collaborative platform for industrial product development and design, Orange Cloud has received a lot of production line and equipment docking needs since the outbreak, such as mask automation production line, unmanned disinfection robot, medical supplies packaging equipment and so on. With the advantages of orange cloud OrangeCDS platform such as online office, precise docking, collaborative design, resource sharing and tripartite supervision, from the Spring Festival to the present, a number of production equipment needs to be efficiently landed on orange cloud platform.
At the same time, Orange Cloud is concerned about the spread of the epidemic, the rapid spread of the virus, the shortage of medical manpower and other problems, and makes use of its own technical advantages to efficiently develop an autonomous navigation electrostatic sprayer disinfection robot in only two weeks. It can help hospitals, schools, industrial plants, shopping malls and other large public places to carry out disinfection work.
