Care and Maintenance

Maintenance Requirements: Regular cleaning of the tube site, monitoring for signs of infection, and ensuring proper function of the tube are essential components of jejunostomy tube care and maintenance.

Additional Information

Related Devices

Associated Terms: Feeding pump, extension sets, and tube securement devices are commonly used in conjunction with jejunostomy tubes to facilitate enteral nutrition delivery.

Innovations and Advancements

Recent Developments: Advancements in jejunostomy tube design have focused on improving tube longevity, reducing the risk of complications, and enhancing patient comfort during use.

Regulatory and Safety Notes

Regulations: Jejunostomy tubes are regulated medical devices, and their use must adhere to relevant medical device regulations and guidelines to ensure patient safety and optimal outcomes.
