Three Ten Ten Views Weihai | Why does this unicorn company an average invention patent per year?

On July 20th, Shandong Weizhong Blood Purifying Products Co., Ltd. Huanbao: overcome the "card neck" technology of domestic medical new materials, which is about to be produced in small batches. The only one in the city.

Behind good things is the continuous innovation support of the enterprise. This 18 -year -old enterprise can only be imported by the raw materials of the main products before 2014. Nowadays, not only do domestic alternatives, the products are also continuously improved, and the new series of products will be launched at the end of the year.

Behind the start of zero to the implementation and running and leading running is the practice of continuous impact towards the higher goals.

Break through the important indicators of "Card Neck" leading similar international products

Entering Shandong Wei Hye Hyepermia Products Co., Ltd.'s dialysis device workshop, the fully automatic production line is running at high speed, and a dialysis device is sent from here to all parts of the country.

For patients who need dialysis, the dialysis device is equivalent to "artificial kidney". The hollow fiber membrane is the core component in the dialysis. Almost all functions are implemented by it, and it is also the most difficult part of technology. Eight years ago, there were only three companies in the world.

At that time, the import cost of 7,000 large hollow fiber film "silk beams" was about $ 10. Packing a complete hemodialysis device required 12,460 silk. The high source cost was finally passed on to the patient. Yuan. The number of full dialysis is 3 times a week, which makes most patients unable to bear it.

"Can we get our own hollow fibrous membrane?" Weigao Group put forward higher goals. This goal finally wrote in 2010 in the five -year development plan of Shandong Weizhizhizhi Purification Products Co., Ltd. Talking about the original intention of the time, the idea of ​​Song Xiushan, the chairman of the enterprise, was pragmatic: "This is a matter of benefiting the patient. After realizing domestic replacement, the price can definitely fall."

After the news came out, there were disdain mockery abroad: I wanted to run without learning to leave? Domestic peers reminded goodwill: "This is a high investment, high risk, and long cycle.

Although the outside voice was complicated, the enterprise was "teaming" quickly, led by three academicians, more than 100 backbone personnel participated, and launched an impact on a hollow fiber membrane.

In 5 years, the company invested a total of 2.3 billion yuan to conduct research and development. Finally, good news came from: On October 9, 2014, Shandong Weizhizhizi Purification Co., Ltd. independently developed a hollow fiber film for application verification.

Authoritative experts have given high evaluation: hollow fiber membrane is one of the "card necks" technologies in the field of blood purification. The products of Shandong Weizhizhi Purification Products Co., Ltd. will accelerate the domestic process.

Various data show that the hollow fiber membrane independently developed by Shandong Weizhizhizhi Products Co., Ltd. has led similar international top products in important indicators such as removal rate and ultrafiltration coefficient.

Since then, Shandong Wei Hye Hyepermia Products Co., Ltd. has won the "tough battle" of domestic replacement, and has made China the fourth country to master the core technology of dialysis. The difficulty of breeding of the product once again showed that the "hard core" showed that the key core technologies could not be bought or invited. Only the hard work and innovation can not be "stuck".

Create an innovative advantage to strive for every product to lead the market

Zhang Cunming, the general manager of Shandong Weizhizhizhi Products Co., Ltd., often led the sales team to talk about the use of the product with the patients in the province's regional central hospitals, recording the suggestions and suggestions mentioned, and feedback to the enterprise R & D center.

There are 400 companies like this, and there are 400 enterprises, and they reach more than 3,000 hospitals across the country every day, just to perceive market demand and changes in the first time.

Focusing on market -oriented, the continuous development, benchmarking, and improvement of products are a must -have questions for enterprises in the past two years. Taking hollow fiber film products as an example, after mass production in October 2014, it has been improved 11 times in eight years. It is currently the fifth -generation product. The new product will reduce the dialysis time from an average of 6 hours to 3.5 hours, and the cost of single treatment has been reduced by one -third.

It is not easy to overcome the "stuck neck" technology that overcome the hollow fiber membrane and continue to maintain the product advantage. It is also difficult to develop the production equipment "by the way."

Entering the production workshop of the enterprise, the 14 processes required for a complete dialysis such as the composite of the raw material reaction synthesis, spinning, drying, injection molding, and molding are completed in one go. Looking at the scene in front of him, Song Xiushan remembered the situation of deciding self -made production line 10 years ago.

The hollow fiber membrane is as thin as a hair, and its production process is also called "spinning". At that time, a German production line needed hundreds of millions of yuan. However, what is more headache than the "buy" production line is later installation and debugging. For more than 10 months, the enterprise and the German expert team installed equipment to debug the production line, but the stability of the offline products and the production line always gapd up with expectations. It is this unconvinced equipment that makes companies decide that it is difficult to develop its own production line.

For more than 9 years, the enterprise had a difficult trek on the road of "spinning", and the light drawings were drawn thousands of sheets, and they had to install and debug themselves by themselves. In the end, in October 2014, the new equipment independently developed by the enterprise was successfully put into production and achieved stable production one after another. Since then, the production line of manufacturing dialysis has achieved localization and no longer depends on imports.

Nowadays, more than 40 products of enterprises have broken foreign monopolies, and have obtained an invention patent a year on average, and there have been 18 items.There are more than 50 varieties of hemodialysis series products, from high, medium, and low -pass clustering membrane dialysis, to blood filter, dialysis solution (powder), plasma separator and other super 100 segmentation products, complete the product step by step to complete the productFull coverage with the service.Time clockwise rotating is late at night. The R & D center of Shandong Weizhong Blood Purification Products Co., Ltd. is still brightly lit.Mu Jiajun, deputy president of the R & D Center, and colleagues sitting around the table to discuss and analyze the experimental data during the day.Right now, the company is related to a new material and miniaturization technology. After success, the size and weight of the dialysis equipment will be greatly reduced to achieve a portable "artificial kidney"."The market is changing. It is definitely not possible to keep a product and a market. We must continue to create new advantages." Mu Jiajun said.(Hi Weihai client reporter Sun Dawei Yang Caiming correspondent Wang Baoming text/picture)
