He dialyzed himself four times a day to maintain his life, but he produced six inventions in two years. He didn't know which came first, tomorrow or the accident, but applied for a patent to save others' lives in time; He hid his suicide note under his pillow, but gave his selfless love to the world; He is the one who needs help most, but he has become the one who helps others the most.
"The flower of dreams will bloom in despair, so we are healthy. What reason is there not to struggle? ! "His classmate Hu's words made us read the whole meaning of a strong life. The world kissed me painfully, and I want to sing it back. In the face of this noble soul, what can we do except shed tears?
On March 2 1, Zou Yongsong got a new patent authorization notice issued by China Patent Office: "* * * enjoys the printer". In the past two years, he applied for six patents and software copyrights. Zou Yongsong is a graduate student of Computer and Communication Engineering College of Changsha University of Science and Technology 15. Born in poverty, he suffered from nephritis since he was a child, and now he has entered the advanced stage. After interviewing Zou Yongsong for several months, the reporter repeatedly recalled the attitude of this young man who lives on dialysis four times a day-if his heart is sunny, he will bloom fearlessly.
Tents in the wind support the desire for life.
Zou Yongsong is doing dialysis for himself in a tent on the outdoor balcony on the 15th floor. Outside the balcony, the north wind roared, as if to tear up the small tent. At noon on February 10, the reporter saw Zou Yongsong for the first time in the rental house in Sifangping, Changsha, and was shocked by this scene.
The dialysate is heated in a heating box, sterilized by ultraviolet lamp and dialyzed in a tent. Every few hours, Zou Yongsong needs to change the dialysate to expel toxins from his body. A bag of two kilograms of dialysate is introduced into the body. If air is accidentally let in, the bones will ache all over. He sneezed in the tent. At this time, the temperature in Changsha is only 3 degrees Celsius.
Since the operation from June 2065438 to June 2007, Zou Yongsong has given himself dialysis four times a day without his relatives. Up to now it has exceeded 1000 times.
Zou Yongsong was born in a peasant family in Lumao Village, Xinhua County, Hunan Province, and suffered from nephritis since childhood. In order to earn money to treat Zou Yongsong, parents, brothers and sisters all left home to work in Guangdong. If he can't find a suitable kidney source, he will always rely on peritoneal dialysis to maintain his life.
"Dad, mom, the condition has deteriorated sharply recently, and the creatinine has exceeded 700. I can't breathe, and I don't have the strength to talk ... The best memory of my childhood is your shoulders, how many roads I walked behind my back, how many mountains I climbed, and how hungry I was. I used to think that after graduation, I would definitely let you live a happy old age. But it backfired. If there is an afterlife, be your son again and repay the kindness of raising in this life. -Your son Zou Yongsong, on the evening of May 2, 20 17. "
Zou Yongsong hid this suicide note under the pillow and took it out every night before going to bed. "One day, I heard my parents say outside the ward,' As long as he is alive, no matter how difficult it is, he must be cured'. I cried at that time. My relatives have not given up, how can I give up? I still have a lot of things to do, and I have to work hard to survive, "Zou Yongsong said.
Zou Yongsong finished her graduation thesis ahead of schedule in her sophomore year, and is currently working as an intern in the unmanned research institute of a university. Get up at 7 o'clock in the first round of dialysis, go out half an hour later, buy breakfast on the way, and walk to work while eating. 12 went home from work for the second round of dialysis. Lunch was cooked the day before and can be eaten as soon as it is hot. 14 went out to work. In the evening, I went to the market and bought some vegetables to go home. The food is ready, and I start the third round of dialysis. Dialysis is over, and scientific research is continued after meals. Dialysis again before going to bed at 23 o'clock-this is a day's life in Zou Yongsong.
On the 27th of the twelfth lunar month, Zou Yongsong's parents came back from Guangdong early to celebrate the New Year with their son. As soon as they entered the door, they saw many paper boxes by the wall-dialysate boxes that my son had been packing for months.
Dialysis solution is bought in a drugstore and delivered to your door every month. 15 boxes once, with 8 bags in each box and 34 yuan in each bag. This is a big expense for Zou Yongsong. He supports his living and medical expenses with the money he earns from working.
Zou Yongsong opened a box of dialysate, slowly flattened the paper box and told his parents, "Waste paper boxes can sell money."
My son is going to have dialysis again. My mother asked with concern, "Why not put the tent in the house to keep warm?"
"This house is shared. I only have a small single room. Putting it in the living room will affect others. " Zou Yongsong replied.
Dinner is ready! In the dim light, a bowl of fish, a bowl of vegetables and meat are fried and eaten. Zou Yongsong and his parents, a family of three, are having a family reunion dinner.
The cold wind whistling, can't blow away the yearning for life, can't blow away the deep affection.
Zou Yongsong, lying in a hospital bed, was haggard. He had just finished surgery, and a dialysis catheter was inserted in his abdomen, but he kept writing something with his mobile phone in his hand. Zou Yongsong greeted his classmates with a smile.
Zou Yongsong's classmates and teachers described this scene to reporters. "Shocked, sick like that, incredibly still doing scientific research! Jon jonsson has been talking with a smile, but we are crying in our hearts. " Classmate Liu Wei said.
During his stay in hospital, Zou Yongsong insisted on using his mobile phone to write application materials for patents and software copyrights.
Since graduate school, Zou Yongsong has successively won the second prize at the provincial level, the third prize at the national level and the national scholarship. He focused on all kinds of inventions, and applied for a patent in March, 2065438+2006-"an emergency rescue method", aiming at providing the best choice for help seekers in the shortest time. If someone is injured and needs treatment, the system will sort the surrounding hospitals from near to far according to the user's location information, and the helper can freely choose according to the feedback information and contact the intended hospital for assistance. It not only improves the efficiency of rescue, but also meets the independent choice needs of help seekers.
Zou Yongsong's research direction is multi-sensor fusion positioning. When he was in hospital, he improved the algorithm of the software package and compiled the real-time electronic map and multi-source fusion positioning system software built by lidar.
"Multi-source fusion positioning can improve the accuracy of unmanned positioning," Zou Yongsong explained. On this basis, another invention patent-the navigation method and navigation system of intelligent robot was born.
Zou Yongsong said that the satellite positioning system may be affected by the environment or weather, resulting in signal loss, so wheel speed or inertial navigation is usually used to obtain the instantaneous displacement increment of the vehicle to calculate the trajectory, thus assisting GPS positioning. However, there is a disadvantage in calculating trajectory with inertial data, that is, errors will accumulate over time. Therefore, he studies how to complement each other by installing various types of sensors on unmanned vehicles, and uses data fusion algorithm to achieve higher precision positioning.
The sickbed can't bind the wings of thinking.
The idea of "* * * enjoying the printer" originated from WeChat photo printer. More than 20 days after the operation, Zou Yongsong returned to the rental house to recuperate. His creative words "* * * Enjoy the printer" have taken shape and started to create in kind. He bought a second-hand printer, used a computer and a QR code scanner online, and then bought a mobile phone card and a network card, and asked colleagues in the research room to design the printer shell packaging. Then, register the portal "Print it" to buy a virtual host and code the software.
The invention can overcome the shortcomings of traditional printing. Zou Yongsong said, "It's very convenient. Users only need to register an account on the website, upload the file to be printed, click on the system to generate a QR code, save it in the mobile phone, and then aim at the QR code scanning port on the printer to print the file. "
2065438+In August, 2007, Zou Yongsong submitted an application for patent authorization of utility model "* * * enjoying printer"; In September, we submitted an application for invention patent authorization of intelligent robot navigation method and navigation system, as well as three software copyright applications of multi-source fusion positioning system, real-time map software built by lidar and automatic printing software.
Why do you do peritoneal dialysis at home instead of hemodialysis with a higher reimbursement rate?
Zou Yongsong explained: "Hemodialysis needs to go to the hospital every 2-3 days, and it takes 4 hours at a time. That is to say, I will go to the hospital every 2-3 days after I leave the hospital, which will definitely delay my work. If I can't make my invention as planned, it will be really painful for me to live. "
"That night I went to the ward to see Song Yong. He is reading a professional Java book. A male student suffering from uremia and wearing a white gown is skinny and wet, but he is still studying hard. The bedside is a flower sent by my classmates ... this scene will never be forgotten by me. Dream flowers will bloom in despair, so why don't we struggle when we are healthy? ! "Classmate Hu said with emotion.
