The Merlyn EndoTube 420055 is a preformed oral endotracheal tube designed for use in airway management during anesthesia, ventilation, or intensive care settings. The 5.5 mm inner diameter is suitable for smaller adult or pediatric patients (depending on clinical judgment). With a built‑in anatomical curve (Magill curve), insertion is facilitated along the natural contour of the airway, reducing resistance and alignment issues. The Murphy tip and accompanying Murphy eye (a side opening near the tip) help maintain ventilation even if the main orifice becomes occluded.

This tube features a high volume / low pressure cuff that is intended to achieve an effective seal against the tracheal wall while minimizing localized pressure on the mucosa, which can reduce ischemic injury during prolonged intubation. The cuff and pilot balloon system are factory tested for leaks, ensuring reliability in sealing performance. The inclusion of a radiopaque line allows confirmation of correct tube placement on imaging, which is critical in airway management scenarios. The universal 15 mm connector ensures compatibility with standard ventilator circuits and breathing systems.

Because the Merlyn EndoTube is packaged sterile and made from medical‑grade resins in a latex‑free format, it adheres to typical safety and compatibility standards expected in clinical use. The tubes are quality controlled for smooth internal surfaces (especially at the Murphy eye), minimizing potential trauma to airway tissues during insertion or manipulation. In practice, this tube offers a combination of dependable sealing, ease of placement, and imaging verification features, making it a useful option in settings requiring reliable airway access and ventilation.
