Abstract: 【Abstract】The clinical use of centralized liquid supply system (CDS system) for dialysis has increased year by year. In China, the set-up of centralized liquid supply equipment is delayed, and no relevant national standards have yet been established. At present, different CDS systems in China have different advantages and disadvantages in clinical use. This paper introduces the basic principles of the two kinds of centralized liquid supply equipment in China, central dialysis concentrate supply system (CCDS) and central dialysis fluid delivery system (CDDS), briefly describes the current situation of clinical use, and expects to develop the centralized liquid supply equipment in the future.
