Teachers and students of Tai'an Technician College self -made "nucleic acid test tube fixed device" help medical staff to improve sampling efficiency

"Don't look at this small design inconspicuous, its role can be great, and it can help medical staff to perform nucleic acid detection and sampling quickly and well." Recently, Liu Dexun, a teacher of the Department of Mechanical Engineering of Tai'an Technician College, is designing and producing for him and students. The "nucleic acid test tube fixed device" apply for patent. "Regardless of the results, we mainly want to encourage students to enhance their awareness of innovation, improve the ability to invent and create, and hand -in -hand operations." Liu Dexun said.

In mid -May of this year, when the students of the Machinery Equipment Professional Skills Contest of the Mechanical Equipment of Tai'an Technician College participated in the test of the whole nucleic acid test, they found that the nucleic acid sampling test tube of the medical staff was unstable. Nucleic acid sampling efficiency. Seeing the "full armed" and hard sampling medical staff, the students wanted to use the design "test tube fixed device" as the starting point to improve the sampling speed of medical staff and help them save time and rest as soon as possible.

"Most of the test tube fixed bases used by medical staff are made of foam. After using it a few times, it becomes very unstable and severe damage. After this idea, I will take my classmates to find production in the training workshop. Materials of the test tube fixed device. "Liu Dexun told reporters that the materials they first used were waste heating tubes, and then based on the test tube data measured from the medical staff, they produced the first generation of products and got the school's nucleic acid testing work. Actual application. "The feedback from the medical staff is very good. After observation and thinking, we found that after using this fixed device, the sampling speed of the medical staff was increased by 20%. However, we also found that this material is easy to oxidize and rust. The size design is not very reasonable. , And it ’s a bit heavy, it is not convenient to carry, the base has insufficient friction, and it is easy to slip." Liu Dexun and the students subsequently improved three times to replace the material of the test tube base into a "aluminum material" that is light and oxidized. It is more beautiful and more reasonable in size. It also adds rubber leather cases to the base to increase friction.

The design and production process of the "nucleic acid test tube fixed device" has made students gain a lot. "Although this fixed device is small, the production process is not simple. We carried out measurement, design, and drawing in the early stage. During the production process, we used professional technologies such as welding, turning, drilling, and numerical control processing." Liu Changshuai told reporters that through the design and production of the "nucleic acid test tube fixor", the hands -on ability with his classmates and the ability to find problems in life and solve problems have been improved. After the praise of the personnel, we feel particularly happy and proud. We will continue to give play to professional expertise and use the skills learned to contribute to the society for society. "

The relevant person in charge of the college introduced to reporters that the teachers and students of the college currently produce 96 nucleic acid test tube fixers, which will be presented to more than 30 schools in Tai'an. "Teachers and students are at a young age, focus on innovation, excellence, and improving the spirit of the craftsmanship, one by one, one -time procedures, and experiments to solve practical problems in work, study, and life. The vast world, "said the relevant person in charge of the school.
