Predawn Spirometry Bin in Tianjin Clinic Room

String lights cast a warm, uneven glow across a stainless steel bin holding disposable spirometry mouthpieces. The white plastic devices rest in neat rows within the perforated metal container, their translucent tips catching the soft illumination against the predawn darkness. The bin sits on a low counter beside a closed examination table draped in crisp white linen. Shadows pool in the corners of the room, deepening the contrast between the bright foreground and the dimming background. A small digital clock displays blue numbers on the wall, while the midsummer air remains still and quiet. The metallic surface of the bin reflects the string lights, creating sharp highlights along its rim. One mouthpiece lies slightly askew near the edge, its blue seal intact.
