Air/Water Channel in Flexible Medical Endoscopes

The Air/Water Channel is a critical functional lumen in flexible medical endoscopes. It is used to deliver air (or CO₂) and water to the distal end of the endoscope to support visualization and clinical operation.

Functions:

1. Air Insufflation
   In gastrointestinal endoscopy, the water & air channel delivers air or CO₂ into the gastrointestinal tract to achieve controlled lumen distension and mucosal fold expansion, thereby improving visualization and procedural conditions.

2. Water Irrigation
   Water is delivered to the distal nozzle to rinse mucus, blood, or tissue debris from the objective lens, ensuring clear and stable imaging.

3. Air/Water Control
   The delivery of air and water is controlled via the air/water valve on the control body, allowing switching between air and water functions.

Materials：

The air & water channel requires excellent flexibility, biocompatibility, and resistance to chemical disinfectants. Commonly used materials include:

• PTFE (Polytetrafluoroethylene)
  Provides an extremely smooth inner surface and outstanding chemical resistance, suitable for applications requiring high durability against disinfectants.

Applications:

Compatible with: Olympus®,Pentax®,Fujinon®
