摘　　要：目前市场上便携式医疗设备采用以锂电池为主,电源适配器为辅的双电源供电模式,需同时配备锂电池充电器和电源适配器,使用过程中很不方便。针对此缺陷,需重新设计电源系统,通过MAX1873实现系统直接由电源适配器进行供电和对锂电池充电,真正实现系统的双电源供电。At present,the power supply of portable medical equipment on the market is lithium battery primary and power adapter supplementary,because it needs the lithium battery chargers and power adapter,it is inconvenient in practice.Aiming at the defects,a novel power supply system is designed to directly charge for the power adapter for lithium battery power by using MAX1873 and to realize the actual double power supply of the system.
