Application‑based segmentation isolates three functional clusters: Diagnostic Endoscopy, Therapeutic Endoscopy, and Surgical Endoscopy. Diagnostic procedures, encompassing gastroscopy, colonoscopy, and bronchoscopy, generate the largest demand for water bottles, representing an estimated 45 % of market revenue due to the high frequency of routine examinations and the need for continuous irrigation. Therapeutic endoscopy, which includes polypectomy, hemostasis, and dilation, contributes about 35 % of the market; the complexity of interventions raises the volume of fluid required for lesion management and device cooling. Surgical endoscopy, covering minimally invasive laparoscopic and thoracoscopic operations, accounts for the remaining 20 % of sales, reflecting its lower procedural count but higher per‑procedure fluid consumption for tissue irrigation and instrument flushing. These application segments collectively define the market’s demand profile, informing production scaling and distribution strategies.
