Dragonfly
EMG Endotracheal Tube Electrode
"Original" laryngeal electrode creates a universal EMG Tube. Apply to 2.5 -10 mm ETT.
Product Overview
Dragonfly EMG endotracheal tube electrode for intraoperative neuromonitoring is universal in function and compatibility.¹ The patented design is available in 1-Channel and 2-Channel configurations for reliable recurrent laryngeal nerve monitoring during surgery. The atraumatic surface electrode applies to any ET tube and connects to any intraoperative nerve integrity monitoring system.
Dragonfly is proven universal and safe, creating the most reliable “EMG tube” on the market.

Product Features

Reliable Recurrent Laryngeal Nerve Monitoring
Dragonfly EMG endotracheal tube electrodes deliver safe and reliable recurrent laryngeal nerve monitoring.
Neurovision Medical Products’ patented EMG electrode attaches to ET tubes from 2.5 mm to 10 mm. Apply any endotracheal tube² for atraumatic laryngeal nerve monitoring.
Dragonfly has 20 years of proven efficacy and predictability in RLN monitoring during surgical procedures.

EMG Electrode For Small Airways
EasyAim Dragonfly 1-Channel Kit can scale to fit the smallest of ET Tubes.
EasyAim provides a 360° coverage of the vocal cords to reduce sensitivity to rotation.
Dragonfly allows clinicians to choose the appropriate ET tube for the patient based on their age and size but functions like an integrated EMG endotracheal tube.³ The EMG electrode is an effective recurrent laryngeal nerve integrity monitor during Thyroid surgery.⁴

Universal EMG Electrode, Seamless Neuromonitoring
Dragonfly EMG tube electrodes are available in multiple sizes and three designs.
Dragonfly is flexible and easy to use. The patented design allows the EMG electrode to be applied to any ET tube (2.5 – 10 ID).
EMG electrode features depth markings to guide placement and improve positioning for reliable EMG signals.
The patented electrode is universal in function and compatibility3,5 for nerve integrity monitoring on any IONM system.
Frequently Asked Questions
Dragonfly is a “stick-on” laryngeal EMG electrode that easily attaches to a standard endotracheal tube to monitor vocal cord activity during surgical procedures where the recurrent laryngeal nerve (RLN) is at risk of injury. Dragonfly has a universal application so most endotracheal tubes can be an EMG tube.
