The reporter learned from Liangjiang New Area that recently, the State Intellectual Property Office issued the "Decision of the State Intellectual Property Office on the Awarding of the 22nd China Patent Award" (Guozhi Shipping Zi [2021] No. 18). Among them, the "Artificial Liver and Kidney Support System" of SWS-5000 series continuous blood purification equipment independently developed and produced by Shanwaishan Company, an enterprise in Liangjiang New Area, won the 22nd China Patent Silver Award.
Gao Guangyong, chairman of Shanwaishan Company, introduced that the traditional blood purification equipment has a single function, requires the combination of multiple devices for multi-organ function support, lacks unified monitoring and safety monitoring, is complex to use, has high treatment costs, and cannot fully meet clinical needs in terms of fluid balance control accuracy and replacement liquid temperature control accuracy.
The SWS-5000 series of continuous blood purification equipment with complete independent intellectual property rights can not only complete the two major functions of lung, heart, kidney, liver support and toxin elimination at the same time, but also establish a core technical platform for extracorporeal circulation life support.
Not only that, the equipment has also realized a number of major technological innovations in the components and key control technologies of the multi-organ functional support system, forming a technical support system for the multi-organ functional in vitro support system.
Among them, the blood purification equipment thermal balance control system based on non-invasive liquid temperature measurement technology and displacement liquid indirect heating feedback regulation technology invented by Shanwaishan has truly realized the accurate feedback control of the displacement liquid temperature in various use environments for the first time in similar equipment, and the control accuracy has reached ±1 °C.
Gao Guangyong said that swS-5000 continuous blood purification equipment (artificial liver + CRRT) has obtained 48 intellectual property rights, including 15 invention patents, 24 utility models, 6 designs, 3 software copyrights, and participated in the drafting of 2 national standards and 1 industry standard.
At present, the equipment has been widely used in many large tertiary hospitals and international medical institutions in China, which has greatly improved the treatment level of kidney failure, liver failure, liver and kidney failure and multi-organ failure and the rescue level of poisoning emergencies.
It is worth mentioning that the equipment is driving the development of Chongqing's blood purification equipment manufacturing industry, parts supporting industry, and medical consumables industry. Gao Guangyong said that the biomedical industry in Liangjiang New Area has huge room for development, and the company will further improve the layout of the whole industrial chain of blood purification equipment and consumables to help the high-quality development of the biomedical industry in Liangjiang New Area.
