本呼吸器是用有机玻璃制作的一种压力限定型(定压式)呼吸器。它直接用射流元件的本体做为呼吸器,结构简单,没有可动部分的磨擦,省掉了某些控制活瓣,而同样可达到呼气和吸气的切换。射流控制装置易于制作,灵敏、稳定、可靠,可以同步辅助呼吸,且适应性强。一、附壁式射流元件的工作原理 Coanda于1932年发现了高速气(或液)流的附壁特性(又名Coanda效应)。如图1所示,其工作原理是从喷嘴喷出的射流与其附
The respirator is made of plexiglass pressure-limiting (constant pressure type) respirator. It directly uses the jet body as a respirator body, simple structure, no friction of the movable part, eliminating some of the control valve, and can achieve the same breath and inspiration switch. Jet control device easy to produce, sensitive, stable and reliable, can be assisted breathing, and adaptability. First, the principle of Coanda Jet Components Coanda discovered in 1932 the Coanda effect (also known as Coanda effect) of high-speed gas (or liquid) flow. As shown in Figure 1, the working principle is that the jet ejected from the nozzle is attached to it
