Every time the quarantine hotel opens its doors, it may face the risk of a virus spreading;
Every time the protective clothing is taken off, it needs to go through 13 procedures, and if you are not careful, you may "take a look" with the new crown virus;
Express delivery, parcels, goods, and cold chain items mailed from high-risk areas at home and abroad may become the carriers of the new crown virus...
In the normalization stage of epidemic prevention and control, how to avoid these key risk points?
On the morning of April 2, the special work conference on the prevention and control of the new crown epidemic under the new situation was held at the Guangzhou Municipal Center for Disease Control and Prevention, and a number of Guangzhou epidemic prevention technology innovations and achievements were unveiled.
【Protective clothing disinfection cabin】
10 seconds of irradiation destroys 99% of the virus
With the global epidemic of the new crown virus, no matter whether it is day or night, wherever there is a need, there is a "big white" figure wearing protective clothing.
However, the removal of secondary protective clothing is demanding, the process is complicated, the time is long, the action is difficult, and it takes 13 procedures to take off once, each of which is a risk point for epidemic prevention and control, and a little carelessness may "take a look" with the new crown virus.
Is it possible to reduce risk by reinventing the Secondary Protective Extraction Process?
To this end, the Guangzhou Municipal Center for Disease Control and Prevention has designed a movable "secondary virus rapid removal cabin" to reshape the secondary protection extraction process and pre-position the virus removal process.
At the exhibition site, a staff member dressed in secondary protection stood in front of the disinfection cabin and pointed the QR code on the 100% UV protection patented face screen above his head to the screen, and the hatch automatically opened. After the personnel entered, the hatch was closed, and more than 4,000 LED ultraviolet lamp beads distributed at different angles disinfected the surface of the secondary protective equipment, including finger seams, armpits, soles of feet and other dead corners.
The entire disinfection process has also been shortened from the original 10 to 20 minutes to about 10 seconds. Studies have shown that after 10 seconds of irradiation, 99% of the virus can be eliminated, greatly reducing the risk of infection during the unloading process.
"The glass door of the disinfection chamber device adopts the design of anti-ultraviolet rays, so that there is zero leakage of ultraviolet rays and no ozone is generated during use. The QR code design also prevents people who are not wearing secondary protection from opening the door by mistake. According to Liu Tong, chief technician of the disinfection department of the Guangzhou Municipal Center for Disease Control and Prevention, the disinfection cabin has been widely used in health stations, isolation hotels, Baiyun Airport and other places.
【Non-contact sampling disinfection door】
Let the quarantine hotel "open the door" every time
All can be sterilized without contact UV
Since last year, there have been cases of infection of workers in centralized isolation places or cross-infection between isolated personnel in many parts of the country.
In the centralized isolation place, the door and door of each routine operation such as measuring body temperature, nucleic acid sampling, food delivery, and garbage collection may cause the risk of virus transmission in the room.
The contactless sampling disinfection "door" workbench presented at the conference can realize the above operations without opening the door during the isolation period of the personnel, and the staff can perform the above operations without contact under the condition of complete physical isolation.
The item delivery compartment on the door is equipped with an LED UV light set that disinfects the items transmitted to the door, including air, for 10 seconds.
At the same time, the door is set up with intercom system, automatic temperature measurement device, door alarm and other modules, which is conducive to the management of isolated personnel, and the privacy button can switch the glass state with one key to protect the privacy of isolated personnel.
【Digital article disinfection machine】
Don't let the logistics chain become a chain of virus transmission
While continuing to do a good job of "external defense input and internal defense rebound", it is also necessary to do a good job of "character defense".
The current logistics industry has established a series of prevention and control and disinfection process measures, but there is still a lack of at-a-glance assessment, recording and traceability of disinfection effects.
In response to this pain point, the Guangzhou Municipal Center for Disease Control and Prevention has developed a digital six-sided disinfection machine to realize that the disinfection effect can be quantified, monitored and traced.
When the package enters the disinfection machine, the ultraviolet light group uniformly illuminates the upper, lower, left, right, front and rear sides of the package, and the position, time and intensity of each beam of light are digitally accurately monitored and automatically reported to the background cloud space, and the killing rate can be directly calculated to ensure that the 6 sides of each item are 100% effectively disinfected. Finally, the machine will print a two-dimensional code on the outer packaging of the package, and the data such as the disinfection effect of the package can be traced by scanning the code.
【Epidemic Prevention and Control Personnel Path Management System】
Precise positioning and quick inspection of close connections
As we all know, large-scale conferences, exhibitions and other crowd gathering activities, it is more difficult to control, once the infected person is found, it is difficult to quickly find close contacts.
The path management system for epidemic prevention and control personnel composed of carriers, base stations and management platforms can provide a sense of security for the public's epidemic management.
Carriers such as card labels have the function of accurately identifying the position, the function of close-range alarm, and the function of automatically identifying the entry and exit, and the corresponding base station measurement results are accurate. It can realize the combination of local data and real-time upload, secure storage of positioning ranging data, support data export, suitable for indoor personnel trajectory tracking, and realize the integrated management of "one person, one code, one label" for multi-information interaction such as personnel identity, indoor positioning, health, and behavior. When an epidemic occurs, the trajectory of personnel can be accurately located and close contacts can be quickly checked.
【Sensorless code checking pass equipment】
No need to brighten the code, brush your face to verify the health code, the itinerary card
In today's normalization of epidemic prevention and control, all units must not slacken off, but the traditional verification of health codes and itinerary cards has a large workload and low efficiency.
To this end, some enterprises have developed a sensorless code access device, through the face recognition technology means, to achieve no sense of mild verification code, the public through the access control through the recognition of face verification health code, itinerary card, improve the health code scan rate and verification speed.
More importantly, the high scanning rate can help trace the source of the epidemic flow, fully grasp the information of the public places visited by risky personnel, and improve the efficiency of epidemic prevention.
The use of the product to reduce labor costs, suitable for health care institutions, office buildings, industrial parks, gate entrances, school gates, property community gates, gymnasium gates, park attractions, government agencies, airports, customs security offices and various business places, but also make the people's lives more convenient, improve the scanning rate.
