Hydrodynamics analysis of waveform of capacity model inspiratory phase / 中国医疗器械杂志

<p><b>PURPOSE</b>To make the capacity model of SMART new-type multi-functional ventilator achieve the capability that the flow can be stable and adjusted accurately.</p><p><b>METHODS</b>To analysis the problems in the course of development with fluid mechanics principle, find the deficiencies of original design and improve it.</p><p><b>RESULTS</b>The inspiratory phase waveform of IPPV. SIMV,etc, breathing pattern presented square wave, achieved the goal of adjustable flow.</p><p><b>CONCLUSIONS</b>Using the fluid mechanics principle guiding the design of ventilator gas circuit can get twice the result with half the effort.</p>
