为培训输液员提供量化评估的培训系统对于为罕见但危急的情况做好准备是很有价值的。开发了一种用于体外循环(ECC)训练的模拟系统ECCSIM-Lite。该系统由包含血液动力学条件模拟程序和带指令的训练场景的计算机系统、流量传感器单元、带有内置水位传感器的蓄水池和带有代表人体的软袋的ECC电路组成。该系统相对简单，易于操作，结构紧凑，价格合理。定量信息被记录下来，包括通过操作旋钮来改变动脉流量，通过操作夹子来改变静脉引流，以及储液器水位的改变；上述参数的时间进程以图形的形式呈现。为了增加训练的真实性，采用了数值-水力循环模型。根据音频和视频字幕形式的场景说明和解释，学员可以在没有教员或计算机操作员的情况下进行自学。为了验证该系统，使用一个简单的培训方案对三名初学者进行了培训；可以定量记录灌注期的表现。总之，ECCSIM-Lite系统有望发挥作用。对于灌流训练，由于记录了关于受训者表现的定量信息，因此可以使用这些数据进行评估和比较。
A training system with quantitative evaluation of performance for training perfusionists is valuable for preparation for rare but critical situations. A simulator system, ECCSIM-Lite, for extracorporeal circulation (ECC) training of perfusionists was developed. This system consists of a computer system containing a simulation program of the hemodynamic conditions and the training scenario with instructions, a flow sensor unit, a reservoir with a built-in water level sensor, and an ECC circuit with a soft bag representing the human body. This system is relatively simple, easy to handle, compact, and reasonably inexpensive. Quantitative information is recorded, including the changes in arterial flow by the manipulation of a knob, the changes in venous drainage by handling a clamp, and the change in reservoir level; the time courses of the above parameters are presented graphically. To increase the realism of the training, a numerical-hydraulic circulatory model was applied. Following the instruction and explanation of the scenario in the form of audio and video captions, it is possible for a trainee to undertake self-study without an instructor or a computer operator. To validate the system, a training session was given to three beginners using a simple training scenario; it was possible to record the performance of the perfusion sessions quantitatively. In conclusion, the ECCSIM-Lite system is expected to be useful. for perfusion training, since quantitative information about the trainee's performance is recorded and it is possible to use the data for assessment and comparison.
