Salem Sump Anti Reflux Valve

The Salem Sump anti-reflux valve is a one-way valve accessory designed to attach to the vent lumen of double-lumen nasogastric tubes, preventing gastric content backflow while maintaining atmospheric venting. By sealing the vent port when reflux pressure occurs, it minimizes patient exposure to infectious materials and reduces unnecessary gown and bedding changes in clinical settings. These valves are supplied sterile and single‑use, ensuring adherence to infection control standards and simplifying bedside preparation. Their compatibility with standard NG tube connectors makes them an easy upgrade for existing enteral suction systems.

• Radiopaque Markings: Facilitates visualization under fluoroscopy or X‑ray for accurate placement verification.

  
  

• Biocompatible Materials: Constructed from medical‑grade silicone or PVC, remaining flexible for up to 30 days in situ.

  
  

• Universal Fit: Compatible with most 5–12 Fr Salem Sump tubes, accommodating varying patient anatomies and clinical needs.

  
  

• Sterile, Single‑Use Packaging: Individually wrapped to maintain sterility, streamline workflow, and reduce cross‑contamination.

Clinical Benefits

By preventing reflux through the vent lumen, the anti-reflux valve significantly reduces the need for gown and linen changes, cutting down on material costs and nursing time. It also neutralizes gastric vacuum pressure once suction is complete, protecting the gastric mucosa and enhancing patient comfort during prolonged decompression. Clinical studies report a marked decrease in NG tube repositioning and aspiration events when using anti‑reflux valves, improving overall patient safety and workflow efficiency.
