体外循环心脏手术模拟系统的研究

The Study of Simulation System for Cardiopulmonary Bypass Cardiac Surgery

根据临床体外循环手术的要求,建立了一套心脏体外循环手术模拟系统。该模拟系统主要由静脉储血腔、可变平衡腔、血液吸引腔、心室吸引腔、阻力阀、压力表以及管路组成。灌注师可利用该系统对预先制定的手术方案进行模拟,预判手术中可能出现的各种异常状况,并进行相应的紧急处理,提高手术成功率,以保证患者生命安全。

According to the clinical requirements of cardiopulmonary bypass surgery, this paper established a simulation system for cardiac surgery which consists of venous reservoir, variable balance chamber, blood suction bag, ventricle suction bag, resistance valves, pressure gauges and tubings. Using the proposed system, perfusionists can mimic the implementation of pre-established surgery strategy, predict various abnormal conditions in the operation, and accordingly take the urgent actions so as to improve the success rate of surgery and to ensure the safety of patients.
