Description

The MIC-KEY Low Profile Jejunal Tube, crafted by Avanos Medical, is a specialized medical device designed for patients requiring enteral nutrition directly into the jejunum. Its low-profile, button-style design offers discretion and comfort, making it suitable for both pediatric and adult patients.

Key Features

• Comfortable Design: The tube sits flat against the skin, minimizing visibility and enhancing comfort. The external bolster allows air circulation and should ideally rest 2–3 mm above the skin.

• Secure Retention: An internal, inflatable silicone balloon secures the tube. The balloon is filled with water, with volumes typically ranging from 5–10 mL for adults and 3–5 mL for smaller tubes.

• Multiple Ports:

• Jejunal Port: Facilitates direct feeding into the small intestine.
• Gastric Port: Available on certain models for decompression, venting, or medication administration.

• Balloon Port: Allows easy inflation and deflation of the retention balloon using a Luer-slip syringe.

• Clear Labeling: Each port is clearly marked to ensure correct usage.

Connectivity and Compatibility

• Connector Options: Available with ENFit or catheter tip connectors, enhancing compatibility with various systems. It is designed to work seamlessly with MIC-KEY extension sets, though not interchangeable with other brands.

• Extension Sets: Detachable extension sets are included, recommended for change every two weeks. These sets swivel for added comfort and can be easily concealed under clothing.

Construction and Visibility

• Effective Feeding: The tube features multiple jejunal exit ports and a weighted portion for proper placement. A radiopaque stripe allows for visualization under imaging, and the tapered distal tip aids in easier insertion.

• Size Variability: Available in French sizes 14 Fr, 16 Fr, 18 Fr, and 22 Fr, with stoma lengths from 1.0 cm to 7.0 cm and jejunal lengths of 15 cm, 22 cm, 30 cm, and 45 cm.

Maintenance and Care

• Sterility: The tube is gamma sterilized and intended for prescription use only.

• Balloon Maintenance: Regular checks of the balloon water volume are advised, with adjustments as necessary for optimal retention.

• Daily Care: Cleaning the tube and stoma site with soap and water is recommended, along with regular rotation of the tube to prevent skin adherence and irritation.

• Flushing: Regular flushing with water before and after feedings and medications helps prevent clogging.

Placement and Use

• Professional Insertion: Typically inserted through a gastric stoma under endoscopic or fluoroscopic guidance. Home replacement is not advised; a trained specialist should handle replacements.

• Feeding Methods: Suitable for long-term enteral feeding and/or gastric decompression, compatible with both continuous and bolus feeding methods. Liquid medications can be administered as directed by a healthcare professional.

Precautions

• Monitoring: Users should monitor for complications such as redness, soreness, granulation tissue, leakage, blockage, or tube migration.

• Troubleshooting: In case of blockage, flushing with warm water is recommended. If balloon deflation issues arise, follow troubleshooting steps or seek medical assistance.

• Compatibility: Ensure only compatible MIC-KEY extension sets and accessories are used, and keep a replacement tube available in case of accidental dislodgement.
