The silicone Salem Sump™ tube with pre-attached anti-reflux valve provides the patient with optimal comfort and protection. The soft silicone tube can dwell up to 30 days. The silicone material remains flexible for optimal patient comfort during nasogastric tube use and removal. The anti-reflux valve prevents stomach contents from exiting the vent lumen. This prevents unnecessary patient gown and bedding changes and reduces the risk of exposure to potentially infectious materials.
