急救人员插入了一根管子以确保气道畅通。

The paramedics inserted a tube to secure the airway.

简单来说，这个充气袋连着一根管子，管子伸到牛的胃里，它能收集奶牛所排放的气体，充满袋子。

Basically, this inflatable bag is connected to a tube running to the cows' stomachs, which collects the gas the cows emits, which fills the bag.

看起来像是P过的吧？但是这是魔法水龙头喷泉，这些水流里其实是藏了一根管子。

It looks Photoshopped, but this Magic Tap fountain actually has a pipe hidden in the stream of water.

我的手上插满了透明的软管，一根管子一样的东西缠在我的脸上，就在我的鼻子下方。我抬起手，想把它拿开。

My hands were all twisted up with clear tubes, and something was taped across my face, under my nose. I lifted my hand to rip it off.
