摘要
以通用微处理器为核心,构成体外全数字化动物心脏起搏器,起搏器设有微机通信接口,通过微机设定起搏器参数。用该起搏器对家兔进行心外膜起搏,满足实验要求。该起搏器全部数字化控制,精度高、稳定性好、参数设定方便、读数直观;起搏器制作容易、成本低廉、体积小,可取代价格昂贵的医用心脏起搏器对动物心脏进行起搏。
In this research and development project,we used the general microprocessor as a core to constitute the animal cardiac pacemaker in vitro.Control of the pacemaker＇s settings was carried out by transmitting parameters through a serial communication interface.Finaly,our pacemaker reaches a satisfying test result in activating the cardiac outer membrane of the rabbits.Full digital pacemaker has high precision,good stability,and has an intuitive way to set parameters.Owing to its smaller size,lower cost,and easier mass production,the digital pacemaker is a good candidate to replace costly medical pacemakers for activating the animal＇s heart.
