Abstract

Cases of cardiac arrests due to cardiovascular ailments have increased recently., portable Current portable resuscitators which can be automatically supply oxygen operated by the pressure of supplied oxygen without manual or electronic actuators are now widely used in emergency worldwide. However, reductions in Pressure drop characteristics through the extended use of this type of resuscitator, however, is are not well-known described. This paper describes the reduction in pressure loss drop performance of the various holes in within the flow control disc of with various hole size of the portable resuscitators using on breathing resistance through the CFD simulation, and suggests the an optimum optimal design of the hole shapes for the minimization of alteration in order to minimize this pressure drops.

최근 심장 혈관 질환 등으로 인한 심정지 발생이 증대됨에 따라, 응급 시 수동 작동 장치나 전기적 구동 장치 없이, 공급 산소의 압력만으로 자동으로 작동되는 휴대용 인공호흡기가 전 세계적으로 보급되고 있다. 그러나 이러한 인공호흡기의 구체적인 압력강하 특성에 대해서는 잘 알려진 바가 없어 본 논문에서는 호흡저항과 관련하여 핵심부품인 유량조절디스크의 다양한 홀 크기에 대한 압력강하 특성을 CFD 시뮬레이션 해석을 통하여 규명하고 압력강하를 최소화할 수 있는 홀 형상의 최적설계 안을 제시하였다.
