Abstract
A respiratory tube assembly includes a three-way connector having first to third connecting sections, a container defining a receiving chamber and having a container surrounding wall and a projection projecting into the receiving chamber, a cover connected to the third connecting section and including a tubular recess, a recess bottom wall having a water-discharge opening, and an outer surrounding wall engaged detachably to the container surrounding wall, a valve head disposed movably within the tubular recess, and a valve rod extending into the receiving chamber. The valve head abuts against the third connecting section when the valve rod abuts against the projection so that the tubular recess communicates fluidly with the receiving chamber through the water-discharge opening. An inner tubular unit extends through the first and second connecting sections.
