Many epidemic prevention "black technologies" are in The first appearance at the Beijing Winter Olympics played a very important role in the smooth convening of the event.</span></p><p style="margin-left:0;text-indent:0;padding:0 0 0 0 ;text-align:justify;text-justify:inter-ideograph;background:rgb(255,255,255)"><span style="color: rgb(34, 34, 34); letter-spacing: 0px; font-size: 18px;">          1.

A few days ago, a reporter from Beiqing Daily saw this cute <a href="https://boocax.com/en/products/sprayer_disinfection_robots.html" target="_self">"atomizing robot"</a> in Ice Cube, with two big eyes and bright eyes, and a custom mask for the Beijing Winter Olympics attached to the mouth. It is reported that the robot uses an ultrasonic atomization device, and can be used for air environment and ground disinfection operations when used with designated disinfectants. Compatible with a variety of disinfectants, at the same time, the atomization speed and spray angle can be adjusted, and the intensity can be adjusted reasonably according to the particle size of different agents to meet the needs of different scenarios. The working area per hour can reach 1,000 square meters.</span></span></p><p style="margin-left:0;text-indent:0;padding:0 0 0 0 ;text-align:justify;text-justify:inter-ideograph;background:rgb(255,255,255)"><span style="color: rgb(34, 34, 34); font-size: 18px;"><img src="/en/upload/images/2022/2/9ee61bf03e47ee9.jpg" style="border: 0; max-width: 100%"/></span></p><p style="margin-left:0;text-indent:0;padding:0 0 0 0 ;text-align:justify;text-justify:inter-ideograph;background:rgb(255,255,255)"><span style="color: rgb(34, 34, 34); letter-spacing: 0px; font-size: 18px;">        The <a href="https://boocax.com/en/products/sprayer_disinfection_robots.html" target="_self">atomization disinfection robot</a> adopts the method of chemical disinfection. It can hold 16 liters of disinfection water at a time, and spray the liquefied gas into the air through the four-way nozzle on the top of the head. The disinfection area can reach 36 square meters in one minute, and a single robot can disinfect The area can cover more than 1,000 square meters at most, and the battery life is 4-5 hours. It is used for the killing of large scenes in the Winter Olympics venues.</span></p><p style="margin-left:0;text-indent:0;padding:0 0 0 0 ;text-align:justify;text-justify:inter-ideograph;background:rgb(255,255,255)"><span style="color: rgb(34, 34, 34); letter-spacing: 0px; font-size: 18px;"><img src="/en/upload/images/2022/2/40081484c70d3e8c.jpg" style="border: 0; max-width: 100%"/></span></p><p style="margin-left:0;text-indent:0;padding:0 0 0 0 ;text-align:justify;text-justify:inter-ideograph;background:rgb(255,255,255)"><span style="color: rgb(34, 34, 34); letter-spacing: 0px; font-size: 18px;">The <a href="https://www.boocax.com/en/products/uv_robots.html" target="_self">UV ultraviolet disinfection robot</a> sterilizes the area through the light wave of ultraviolet 254 nanometer ultraviolet wavelength, and the killing effect is very thorough.</span></p><p style="margin-left:0;text-indent:0;padding:0 0 0 0 ;text-align:justify;text-justify:inter-ideograph;background:rgb(255,255,255)"><span style="color: rgb(34, 34, 34); letter-spacing: 0px; font-size: 18px;">     </span><span style="color: rgb(34, 34, 34); font-size: 18px; letter-spacing: 0px;"> It is reported that the disinfection robot is favored by the organizing committee because of its convenient and easy-to-operate characteristics that only need to add disinfectant in advance every day, and it can start the disinfection task at the set time.</span></p><p style="text-indent: 0px; margin-left: 0px; padding: 0px; text-align: justify; background: rgb(255, 255, 255);"><span style="font-size: 18px;"><span style="letter-spacing: 0px; text-indent: 64px; font-size: 18px; color: rgb(34, 34, 34); font-family: "times new roman";" times="" new="">        </span><span style="font-size: 18px; color: rgb(51, 51, 51); letter-spacing: 0px; text-indent: 64px;" times="" new="">2.

We learned that this is the latest application technology jointly developed by researchers from Tsinghua University, Peking University and other researchers who took 8 months to urgently tackle key problems.</span></p><p style="text-indent: 0px; margin-left: 0px; padding: 0px; text-align: justify; background: rgb(255, 255, 255);"><span style="color: rgb(51, 51, 51); letter-spacing: 0px; text-indent: 64px; font-size: 18px;">    The diameter of the aerosol is less than 100 microns, the transmission distance is more than 1 meter, and it can be directly inhaled into the lungs. It is one of the important transmission routes of the new coronavirus. According to the project leader, the volume of aerosol samples in the air is large, but the viral load is relatively low, which requires very sensitive detection methods.</span></p><p style="text-indent: 0px; margin-left: 0px; padding: 0px; text-align: justify; background: rgb(255, 255, 255);"><span style="color: rgb(51, 51, 51); letter-spacing: 0px; text-indent: 64px; font-size: 18px;">    It is reported that the bio-aerosol new coronavirus nucleic acid monitoring system consists of a portable aerosol collector and an integrated high-sensitivity new coronavirus nucleic acid detector. Among them, the aerosol collector is small and lightweight, suitable for use in small confined spaces such as warm-up rooms and referee rooms. After the instrument is turned on, an air cyclone is guided into the collection tube at a flow rate of more than 400 liters per minute, and particulate matter such as aerosols in the air will be thrown into the collection tube. The collection tube contains 4 ml of virus inactivation solution. Once the aerosol contains virus, it will be inactivated to ensure the safety of sampling and subsequent testing personnel. </span></p><p style="text-indent: 0px; margin-left: 0px; padding: 0px; text-align: justify; background: rgb(255, 255, 255);"><span style="color: rgb(51, 51, 51); letter-spacing: 0px; text-indent: 64px; font-size: 18px;">    The testing personnel regularly take out the concentrated solution in the collection tube, transfer it into the sample tube, and then put it into the chip cartridge, and put it in the new coronavirus nucleic acid detector for testing. "Although the curve of the negative sample will fluctuate slightly, it is basically flat, while the curve of the positive sample will rise in an S shape, which is clearly distinguishable from the negative sample." The project leader introduced that the detector uses a microfluidic platform combined with a new type of Nucleic acid extraction and amplification technology makes the detection sensitivity of the new coronavirus 10 times higher than that of conventional methods.</span></p><p style="text-indent: 0px; margin-left: 0px; padding: 0px; text-align: justify; background: rgb(255, 255, 255);"><span style="color: rgb(51, 51, 51); font-size: 18px; letter-spacing: 0px; text-indent: 64px;">    During the Beijing Winter Olympics, more than 100 sample collectors will be "on duty" in multiple venues of the Winter Olympics, and multiple detectors will also be installed at the temporary testing station. The whole process from sampling to receiving and transporting to testing results will take no more than 4 hours. "If weak positive or positive samples are found in the test, the laboratory will immediately communicate with the epidemic prevention department and start a series of epidemic prevention processes such as environmental disinfection and personnel detection and tracking as soon as possible." The project leader said.</span></p><p style="margin-top:0;margin-right:0;margin-bottom:0;margin-left:0;text-indent:64px;padding:0 0 0 0 ;background:rgb(255,255,255)"><span style="color: rgb(51, 51, 51); letter-spacing: 0px; font-size: 18px;">For more coverage of the Winter Olympics, see The New York Times Sports Column, "The coronavirus continues to sideline Olympic athletes as they gear up for competition" by Alexandra E.
