Description

The 14Fr 2.0cm 45cm MIC-KEY Low Profile Gastric-Jejunal Tube by Avanos is a specialized medical device designed to meet the needs of both pediatric and adult patients requiring simultaneous jejunal feeding and gastric decompression. Its low-profile design ensures comfort and discretion, sitting close to the skin to minimize the risk of accidental dislodgement.

Key Features

• Dual Access: The tube provides dual access, allowing for effective feeding into the jejunum while enabling gastric decompression or medication administration through the stomach.
• Clearly Marked Ports: It features clearly marked gastric and jejunal ports for safe and accurate connections, along with a separate balloon port for inflation and deflation.
• Silicone Balloon Retention: The internal silicone balloon serves as a retention mechanism, with a recommended fill volume of 5–10 mL using sterile or distilled water.

Design and Visibility

• Weighted Jejunal Portion: The weighted jejunal portion helps maintain proper positioning within the small intestine, complemented by multiple jejunal exit ports for enhanced nutrient distribution.
• Radiopaque Stripe: A radiopaque stripe ensures visibility under X-ray, aiding in accurate placement confirmation.
• Anti-Reflux Valve: Equipped with an anti-reflux valve, the tube helps prevent leakage when not in use.

Ease of Use

• Tapered Distal Tip: The tapered distal tip facilitates easier insertion, reducing potential trauma.
• External Bolster: An external bolster secures the tube, ideally resting 1–3 mm above the skin.
• ENFit Connectors: ENFit connectors provide secure, standardized connections to extension sets and syringes.

Included Accessories

Detachable ENFit extension sets are included for feeding, medication, and venting purposes. These can be removed for discretion, allowing the tube to remain unobtrusive under clothing. Compatibility with MIC-KEY extension sets and ENFit syringes is recommended for optimal performance.

Intended Use

This tube is intended for long-term enteral nutrition, typically used as a replacement or transition tube after initial placement with a different device. Placement is performed through an abdominal stoma by a healthcare professional using image guidance. Home replacement is not advised, and proper clinical procedure is required for both placement and replacement.

Maintenance

Regular maintenance includes daily cleaning of the stoma site, external tube, and ports with mild soap and water. Balloon water volume should be checked weekly, and flushing with water before and after feeding or medication is essential to prevent blockages. Monitoring for signs of infection, irritation, leakage, or migration is crucial for safe and effective use.

Safety Notes

The tube should not be rotated to avoid migration or kinking, and if dislodged, immediate action is necessary to maintain tract patency. Feeding should be paused if the tube migrates into the stomach until proper positioning is confirmed by imaging. Regular changes every 4–6 months or as directed by a clinician ensure continued functionality and safety.
