一、引言呼吸器是一种常用的医疗器械,可用于各种呼吸不全、呼吸衰竭和循环呼吸停止的复苏抢救,以及呼吸管理等过程。为了安全、可靠地监护手术过程中的麻醉和呼吸,近年来国际上已发展了多种型式的气动呼吸器。我们研制的流控式气动呼吸器主要用于麻醉手术,实际上它也可以单独使用。 I. Introduction Respirator is a commonly used medical device that can be used for various respiratory insufficiency, resuscitation and resuscitation of respiratory failure and respiratory arrest, and respiratory management processes. In order to safely and reliably monitor anesthesia and respiration during surgery, various types of pneumotachors have been developed internationally in recent years. We developed flow-controlled pneumatic respirator is mainly used for anesthesia surgery, in fact, it can also be used alone.
