摘要
本文针对目前一些国产呼吸机控制电路的缺陷，提出了用单片机程控系统取代原有的模拟电路控制系统的方法。改进后明显提高了呼吸机的稳定性，可靠性和安全性，且成本低，易于操作。经过临床实用，效果良好。
In order to improve the performance of the domestic ventilator a single-chip microprocessor system substituting original analogue circuits is suggested by the authors. The new control system greatly improved the stability, reliability, and safety of the ventilator. The refitment is easy to implement, and the cost is low. It's effect is good after clinical application.
