초록
본 연구는 급성호흡부전환자를 치료하기 위하여 사용되고 있는 혈관 내 폐 보조장치의 기체전달을 향상시키기 위하여 중공사 막에 진동기법을 사용하여 기체전달을 향상시키고자 시도하였다. 그리고 혈관 내 폐 보조장치를 정맥에 삽입하기 전, 혈관 내 폐 보조장치의 설계조건을 실험적 모델을 통하여 기체전달을 예측할 수 있는 예측식을 만들고자 하였다. 실험결과, 본 연구에서는 진동기법이 기체전달을 향상시키는데 효과적임을 확인할 수 있었다. 뿐만 아니라, 충진율과 가진 주파수의 함수관계를 이용하여 기체전달을 예측할 수 있었다. 실험에 의하여 얻어진 결과는 예측 식에 의하여 얻어진 결과와 유사한 결과를 얻었다. 그러므로 본 연구에서는 충진율과 가진 주파수의 함수를 이용하여 VIVALD의 기체전달을 예측할 수 있었다.
In this paper, we tried to improve gas exchange of the vibrating intravascular lung assist device(VIVLAD) using vibrating method in the hollow fiber membrane, for the patients suffering from acute respiratory distress syndrome(ARDS). And we tried to formularize prediction equations to make a prediction about gas transfer for designing intravenous artificial lung assist device, and designed modules under various conditions were studied through an experimental modeling before inserted the artificial lung assist device into as venous. As a result, we are convinced that vibration method is very useful for the gas transfer increasing. Also, we can estimate the gas transfer as a function of the packing density and excited frequencies. The gas transfer obtained from the experiment was similar to that from the prediction equation, confirming the usefulness prediction equation. Therefore, we can estimate the gas transfer of the VIVLAD as a function of the packing density and excited frequencies.
