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