Description

The MIC-KEY Low Profile Gastric-Jejunal Tube by Avanos is a specialized enteral feeding solution designed for both pediatric and adult patients. This device facilitates simultaneous jejunal feeding and gastric decompression, providing essential access to the stomach and jejunum for the administration of tube feeds, liquids, medications, and decompression.

Key Features

• Tube Specifications:
• Diameter: 14 French (Fr)
• Stoma Length: 2.5 cm

• Jejunal Length: 45 cm

• Design:

• Low-profile design sits close to the skin, enhancing comfort and minimizing the risk of dislodgement.
• Multiple jejunal exit ports for improved nutrient distribution.

• Weighted jejunal portion to help maintain position.

• Visibility and Safety:

• Radiopaque stripe for X-ray visibility.

• Clearly marked gastric and jejunal ports for safe and correct connections.

• Retention and Anti-Reflux:

• Internal balloon retention system with a recommended fill volume of 7 mL (max 10 mL) using sterile or distilled water.

• Anti-reflux valves on the external base to minimize leakage.

• Insertion and Connection:

• Tapered distal tip for easier insertion.
• ENFit connectors for secure, standardized connections.

Kit Contents

• ENFit extension sets (continuous and bolus feed extension sets, typically 12 inches each)
• 35 mL syringe for venting, priming, and flushing
• 6 mL Luer slip syringe for balloon inflation and deflation

Material

Constructed from medical-grade silicone, this tube is designed for long-term use, suitable for both pediatric and adult patients.

Maintenance and Care

• Daily Care: Clean the tube and stoma site with mild soap and water.
• Balloon Maintenance: Check balloon volume weekly and refill as needed.
• Flushing: Flush the tube before and after each use to prevent blockages.
• Rotation: Do not rotate the tube as it extends into the jejunum.

Compatibility

• Use only MIC-KEY extension sets; extensions from other brands are not interchangeable.
• Replace extension sets as recommended.

Monitoring

• Monitor for signs of infection, leakage, or displacement.
• Ensure the external base rests 1–3 mm above the skin.
• Tube replacement should be determined by a clinician, especially if stoma length or patient weight changes.

Special Instructions

• Placement requires an endoscopic procedure and cannot be replaced at home.
• Administer medications through the jejunal port only if advised by a healthcare professional.
• Align black lines and turn extension tubes clockwise up to ¾ turn to connect; do not overtighten.

Troubleshooting

Common issues such as leakage, blockage, or tube migration can be managed by checking balloon volume and flushing with warm water. Regular care helps prevent complications like granulation tissue, skin irritation, and leakage.
