A kind of pumping phlegm pipe cleaning mechanism is arranged in one endotracheal tube of what, and taking out phlegm pipe cleaning mechanism includes a pumping phlegm tube body and an at least scraper component. Taking out phlegm tube body has a proximal end and a distal end, and an at least scraper component system sets the inner wall that takes out the distal end of phlegm tube body and supports tug what endotracheal tube, and scraper component system in bowl shape and has elasticity； Wherein, when length direction back and forth movement of at least scraper component along the endotracheal tube, which swings and the inner wall for the what endotracheal tube that exerts a force with respect to the pumping phlegm tube body, the dirt on inner wall to remove the attachment what endotracheal tube.一種抽痰管清潔機構，設置於一氣管內管中，抽痰管清潔機構包括一抽痰管本體及至少一刮除構件。抽痰管本體具有一近端及一遠端，所述至少一刮除構件係設於抽痰管本體之遠端並抵掣於氣管內管之內壁，且刮除構件係呈碗杯狀且具有彈性；其中，當該至少一刮除構件沿著該氣管內管的長度方向往返運動時，該至少一刮除構件相對該抽痰管本體擺動而施力於該氣管內管之內壁，以去除附著於該氣管內管之內壁上的汙垢。
