【摘要】透析用集中供液系统(dialysis centralized liquid supply system，CDS)在临床上的使用比例逐年增高，国内的集中供液设备起步较晚，且仍未有相关的国家标准。目前国内各类集中供液系统在使用上各具优势与不足，本文介绍了目前国内中央浓缩液供应系统(central dialysis concentrate supply system，CCDS)与中央透析液供应系统(central dialysis fluid delivery system，CDDS)2 大类透析用集中供液设备的基本原理，简述其使用现状，并展望了未来集中供液设备的发展趋势。

【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.
