3 seconds, no contact with the hand!The invention of Shenzhen high school students makes the sampling staff directly call too convenient

Students participating in the invention show the use of hand disinfection instruments

"It only takes 3 seconds to complete the full coverage of the hand, it is fast and efficient and there is no contact, it is really convenient!" Recently, a portable epidemic called "epidemic companion wisdom" for first -line nucleic acid detection sampling personnel used The prevention and control intelligent atomization hand disinfection instrument fire, and what is unexpected is that the inventor of such a "black technology" product is a group of students from high school students from Guangming District.

What principle does this hand disinfection instrument use? What is the original intention of invention? The reporter came to the Guangming District Senior High School to find out.

Three generations of change liberation sampling personnel's hands

"Hello, disappear." "I am, do you need help?" "Open the device." "Okay, the" epidemic companion wisdom "has been opened." The small hand disinfection instrument is very conspicuous and is having an intelligent dialogue with the user. The students participating in the invention Ni Weihao and Zhan Kaijun introduced to reporters that the instrument uses the "atomized disinfection+UVC Deep UV" dual elimination, and adds gesture action recognition and laser distance induction technology to achieve rapid start. Rubbing repeatedly, you can cover your hands in 3 seconds. The instrument also connected "Baidu AI" through IoT technology to achieve intelligent voice control, exempt from contact throughout the process, and further reduced the possibility of virus transmission.

The initial cause of this invention stems from the hands of the nucleic acid sampling personnel under the epidemic. The relatives of Zheng Chenqi are engaged in the sampling of nucleic acid. Because the disinfectant is pressed for a long time, the back of the palm of the hand has bruises. 15 members formed a team.

From the simple drafts on the paper to the establishment of 3D models, to the first test ... In October 2021, the first generation of "epidemic companion wisdom" came out, but the team was distressed. "The evaluation given after the use of medical staff is not high, because the product is open, waste a lot of disinfectant, and also causes the detection point to diffuse the mist." Therefore, the project team Chen Junxin and 鄢 from the scientific mentor of the Star Maker Practice Room Chen Junxin and 鄢 鄢 鄢 鄢 鄢 鄢Kaiti for help. Under the guidance of the teacher, the members carefully analyzed and rectified, made the second -generation products, and optimized the size on the basis of this, and finally realized the research and development of the third -generation "epidemic companion". "Now our hands are not only suffering, but also greatly improved the efficiency of disinfection." The staff participating in the trial nucleic acid test said satisfactorily.

Applying for patents to learn the exhibition style

I learned that this invention of senior middle school students in Guangming District has been present to learn guidance in recent days. Zhao Jianhua, a professor at Southern University of Science and Technology, said that "epidemic companion wisdom" is very practical. Students have improved technical awareness, engineering thinking, innovative design, graphic expression, and materialization ability during the production process, which also meets the core literacy of general technology disciplines.

The school teacher Chen Junxin introduced that recently, the student team will bring this invention to participate in the eighth China International "Internet+" College Student Innovation and Entrepreneurship Competition Guangdong Provincial Entrepreneurship Finals. In addition, the product is currently applying for three intellectual property rights and patents, and will be incubated as soon as possible to timely invest in first -line nucleic acid testing.
