Figure 3 The simplified negative-pressure nasoesophageal drainage (SNPND) device and procedural demonstration. (A) Clinical photograph showing yellow purulent effluent drained through the nasogastric tube. (B) Composite schematic illustration combining the disposable negative pressure drainage ball and sagittal computed tomography imaging, demonstrating the SNPND procedure. The end of the nasogastric tube is positioned in the mid-esophagus, and it is connected to the external negative pressure ball. (C) Close-up photograph of the distal end of the 16-Fr nasogastric tube, showing 3 factory-manufactured side holes (each 3 mm in diameter) spaced 3 cm apart at different orientations along the distal segment.
