動脈フィルター気泡除去装置の揺動振幅が気泡除去効率に与える影響調査

Bubble removal is indispensable in the priming of the artificial heart-lung circuit. This bubble removing operation is important to remove bubbles quickly and accurately, and in general it is a heavy burden on the person in charge to manually perform. Therefore, in order to reduce this burden, we have been studying bubble removal devices. In this study, the amplitude of the mechanical vibration of the arterial filter was changed, and the effect at each amplitude was investigate：ed as efficient bubble elimination was obtained by applying constant vibration to the arterial filter using this device. We conducted experiments to change the amplitude of the arterial filter in three steps. Three kinds of amplitude of 10 °,20 °,30 ° were given, and a vibration with a constant frequency of 10 Hz was given for 10 seconds. As a result of the experiment, bubbles could be eliminated satisfactorily at an amplitude of 30 °. However, at an amplitude of 20 °,10 °, minute bubbles remained. In the future, we will investigate the influence of the vibration cycle on bubble removal in the bubble removing device.
