Abstract:
1. A respiratory tube assembly comprising: an outer tubular unit and an inner tubular unit, said outer tubular unit including a first three-way connector, a first tubular sleeve, a second tubular sleeve, and a water-collecting device; said first three-way connector having a first main tubular section, first and second connecting sections extending outwardly and respectively from two opposite ends of said first main tubular section and extending in two opposite directions along an axis of said first main tubular section, and a third connecting section extending from said first main tubular section between said first and second connecting sections along a direction transverse to said axis, each of said first, second, and third connecting sections having a diameter smaller than that of said first main tubular section; said first tubular sleeve having a first end portion sleeved on said first connecting section, and a second end portion opposite to said first end portion; said second tubular sleeve having a third end portion sleeved on said second connecting section, and a fourth end portion opposite to said third end portion; said water-collecting device including a container, and a cover covering said container and connected to said third connecting section, said container being connected detachably to said cover and having a container bottom wall, a container surrounding wall extending upwardly from and cooperating with said container bottom wall to define a receiving chamber, and a projection projecting from said container bottom wall into said receiving chamber, said cover including a top wall that is recessed downwardly to form a tubular recess, a recess surrounding wall surrounding said tubular recess, a recess bottom wall connected to said recess surrounding wall oppositely of said top wall, and an outer surrounding wall extending downwardly from an outer end periphery of said top wall, surrounding said recess surrounding wall, and engaged detachably to said container surrounding wall, said recess bottom wall extending into said receiving chamber and having a water-discharge opening; said water-collecting device further including a valve member that has a valve head disposed movably within said tubular recess, and a valve rod extending downwardly from said valve head into said receiving chamber through said water-discharge opening to abut against said projection, said valve head being spaced apart from said recess bottom wall and abutting against said third connecting section when said valve rod abuts against said projection so that said tubular recess communicates fluidly with said receiving chamber through said water-discharge opening; said inner tubular unit extending from said first tubular sleeve into said second tubular sleeve through said first and second connecting sections and said first main tubular section of said first three-way connector, and having a fifth end portion proximate to said second end portion, and a sixth end portion proximate to said fourth end portion.
