She used it as a "medicine" to fight against inflammation

If there are only key technologies and no understanding of market demand, engineering prototypes and products cannot be formed, cannot enter the clinic, and cannot alleviate the pain of patients.

Shoulder-length hair, sweet smile, soft words, it is difficult to imagine such a gentle woman, before an interview with reporters, on the value of R & D results and market outlook, and financiers lip gun tongue sword.

"China-made medical devices may not be self-worth, by the price advantage of occupying the market, our technological strength, is not lost foreign products.

Today’s Cui Jinjiang, on the one hand, wants to find the excitement of doctors, leads the scientific research team to brainstorm with doctors, develops medical devices suitable for China’s national conditions, and relieves patients’ pain; on the other hand, he has to look for market opportunities and consider how to make domestically produced products that meet China’s national conditions Medical equipment enters hospitals and thousands of households.

"If there are only key technologies, no communication with doctors, and no understanding of market needs, engineering prototypes or products cannot be formed, cannot enter the clinic, and cannot alleviate the pain of patients.

The movie "Jiang Zhuying" illuminates the young optical dream

As a teenager, Cui Jinjiang dreamed of becoming a doctor or teacher.

"I still remember the scene in the movie where Jiang Zhuying, a famous optical expert in my country, was working on the optical machine debugging table of Changchun Institute of Optics and Precision Mechanics (the predecessor of Changchun University of Science and Technology).

Cui Jinjiang's optical enlightenment was inspired by optical pioneers and influenced by his peers.

A few years later, my cousin was admitted to the Changchun Institute of Optics and Fine Mechanics.

Changchun Institute of Optics and Fine Mechanics is the first university in New China that specializes in cultivating optical talents.

"Mysterious, challenging, and meaningful.

Approaching his Ph.

In 2009, the Suzhou Medical Institute began preparations, and Cui Jinjiang was tempted.

Cui Jinjiang submitted his first job application resume to Suzhou Medical Institute and successfully received the admission letter.

Closely aware of the pain of a loved one who died of cancer

As the first group of entrepreneurs in the Suzhou Medical Institute, Cui Jinjiang's scientific research road was not smooth.

“When we first applied for the project, we all hoped that the more innovative the technology, the better, but in the end we found that the results were not grounded, and it was difficult for companies to transform them into products, and it was difficult for the instrument to be popularized in clinical applications.
Then, we changed our thinking.
Facing the clinic, I hope to help doctors solve problems and relieve patients' pain.
" She recalled.

"As an electromagnetic wave, light can affect the distribution of ionic magnetic fields inside and outside the cell membrane of the human body.
Proper and deep illumination can help cells enhance their ability to fight inflammation, improve local immunity, promote drug absorption and metabolism, and promote body tissue repair.
" Cui Jinjiang said that at present, red, blue, and infrared have been widely used in clinical superficial treatment of the human body; but in the treatment of some organ diseases, it is necessary to deeply penetrate the body surface to reach the focus of the deep phototherapy equipment.
At that time, most of these equipment Come from abroad, and the price is expensive.

Having found this pain point, since 2014, Cui Jinjiang has led a team to develop a deep-layer spectroscopy device, hoping to enable Chinese patients to use high-quality and inexpensive advanced equipment, but they encountered difficulties in the initial stage.

“Deep light has a higher energy.
If you can’t turn down its energy, it’s easy to burn your skin.
We have spliced ​​various lasers and LED lights, combined various filters, and shaped beams, but none of them can Let the energy meet expectations, which makes us very distressed.
" Cui Jinjiang said.

Just when the project almost stagnated, Cui Jinjiang's inspiration came to light.
"If light interacts with organs, it must first pass through the skin, and human tissues, including skin tissues, have a water content of more than 70%.
I am thinking, if some liquid devices are added to the treatment equipment, will it be enough? Achieve safe deep penetration?" After verification, Cui Jinjiang found that this idea is feasible.

Later, the team installed a liquid device in the treatment instrument, used the liquid to absorb the heat of light, then used chemical components to simulate human skin tissue, and integrated environmental factors, and finally realized the world's leading deep treatment spectroscopy technology with its own technical solutions.
Won the gold medal of the 10th International Invention Exhibition in 2018.

something unexpected may happen any time.
The breakthrough in scientific research didn't make Cui Jinjiang excited for long, and life gave her a hard blow.

In January 2016, her close relatives were diagnosed with kidney cancer and it was in the advanced stage.
During that time, Cui Jinjiang would often accompany his family to the hospital to collect pleural effusion, but unfortunately, after 7 months, his family died unfortunately.
The departure of the loved ones made her feel the pain of the patient more deeply.
After that, she paid special attention to how to relieve the pain of cancer patients.

Cui Jinjiang still remembers that a 40-year-old male patient was suffering from pain caused by pleural and abdominal effusion.
The existing treatment plan could not relieve his pain.
With the idea of ​​giving it a try, the doctor recommended him to use the deep spectrum treatment instrument developed by Cui Jinjiang's team.

During the dozens of minutes of treatment, Cui Jinjiang stood in the corridor of the hospital, anxious and full of expectations.
When the patient finally gave a positive evaluation, she was so excited that she almost shed tears.
"At that moment I was very pleased, it was a great encouragement to me.
" She recalled.

Up to now, Cui Jinjiang has led the team to undertake more than ten national, provincial and municipal scientific research projects, developed more than ten advanced medical products with independent intellectual property rights, and successively obtained 17 national authorized invention patents.

Encouraging and calling for the development of the medical device industry

For many years, Cui Jinjiang, who has been wandering between patients and doctors, knows that if you want medical devices to enter the hospital and go to the patients with temperature, you must be friends with the doctor.
"Doctors have rich clinical experience.
Only by understanding the needs of doctors can they design medical equipment that they are willing to use and like to use," she said.

In the past two years, Cui Jinjiang has often traveled between major hospitals in search of scientific research inspiration, but at first he bumped into walls.
"Objectively speaking, due to the gap between domestic medical equipment and foreign products, many doctors prefer to use imported medical equipment, so when we first promoted it to hospitals, doctors were not very willing to use it.
" She said.

But Cui Jinjiang was not discouraged.
While perfecting her technique, she frequently communicated with doctors.
A few years ago, she met Hu Yi (a pseudonym), a dermatologist at a tertiary hospital in Shanghai.
With years of clinical practice, Hu Yi believes that the miniaturization and integration of dermoscopy will be the future trend.

And this judgment and the idea was Cui Jinjiang coincide, she immediately joint Hu Yi, the Shanghai Science and Technology Committee will be submitted to the scientific and technological achievements and industrialization project proposals should be developed in cooperation with Hu Mobile Optical dermoscopy , The project was finally approved.

In the following year, Cui Jinjiang's team began to design the divergence angle, color temperature, and light source distribution of the LED light source, and looked for customized equipment from the light source company.
In 2018, Cui Jinjiang's team developed the first medical-grade portable optical dermatoscope in China, and passed the classification of new medical device products.
The imaging quality surpassed imported products, and the cost was only half of foreign products.

"We must not only do scientific research in the laboratory, but also transform key core technologies into products.
This requires mobilizing more doctors to participate, starting from the needs of the industry, and engaging in joint research.
" Cui Jinjiang said that her unit has flexibility.
The combination of medical and industrial incentives to increase the participation of doctors.
"For example, if a doctor has an original scientific research idea, after it is converted into a product in the future, the doctor can have a certain percentage of conversion income, up to 60%.
"

Cui Jinjiang, who has constantly introduced new ideas in scientific research, is also advocating for the development of the medical device industry in participating in politics.
The subject of her research, "Recommendations on Promoting the High-Quality Development of the Medical Device Industry" was determined to be a collective proposal by the Suzhou Municipal Committee of the Jiu San Society.
This is the "Several Measures to Accelerate the High-Quality Development of the Suzhou Biomedical Industry" issued by Suzhou in 2019.
》Provides decision-making reference.

Today, Cui Jinjiang has a diverse identity, but what she values ​​most is the role of a scientific and technological worker.
"I hope to develop more domestic medical devices that can be recognized by doctors, enter clinical use, and have a certain market share.
In the future, when everyone talks about domestic medical devices, they will no longer just think of low-end consumables, but domestic medical devices will also It can be compared with international advanced products.
" She said.
