Dragonfly

Stick-On Electrode for RLN monitoring

Dragonfly is the original EMG electrode that attaches to any size endotracheal tube for atraumatic laryngeal monitoring.

Product Overview

Dragonfly is the original atraumatic EMG electrode. The patented design is available in 1-Channel and 2-Channel configurations to monitor RLN activity in a variety of procedures. Dragonfly electrodes are applied to any standard ET tube and are compatible with any single channel or multi-channel nerve monitoring system.

Safe, effective, Reliable

Dragonfly laryngeal electrodes monitor nerve activity during thyroid and other surgeries where the RLN is at risk.

The atraumatic electrode attaches to any endotracheal tube (2 mm - 9.5 mm). In addition, all Dragonfly electrodes feature depth markings to guide placement and improve positioning for reliable EMG signals throughout the procedure.

Dragonfly is the original "stick-on" RLN electrode that features NMP patented technology.

RLN 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.

Multiple sizes, universal design

Dragonfly electrodes are available in multiple sizes and three designs. The flexible design is easy-to-use and allows a Dragonfly to be attached to an endotracheal tube (2 mm - 10 mm) to deliver continuous RLN monitoring on any nerve monitoring system.

Frequently Asked Questions

Dragonfly is a “stick-on” 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 electrodes are available in 1-channel, 2-channel, and a .5 channel with color-coded lead wires and standard DIN (42802) connectors for universal function and compatibility on single and multi-channel IOM systems.

Dragonfly easily attaches to most endotracheal tubes (size 2 mm to 10 mm).
The electrode should not be used with an ET tube pre-treated with silicone or other lubricants.

The EMG function of the Dragonfly is the same as an integrated EMG ET tube. The main difference is that a Dragonfly electrode is applied to the ET tube before the procedure and can be scaled to fit most ET tube sizes, including half sizes and as small as a 2 ID ET tube.

Dragonfly electrodes deliver EMG signals on most sizes and types of ET tubes and connect to most nerve monitoring systems. For example, EasyAim (LSE600MSP) attaches to ET tube sizes 2 ID, 3 ID, 4 ID, and 5 ID.

Dragonfly is universal, allowing for safe atraumatic RLN monitoring in smaller, more difficult airways on any IOM nerve monitoring system.

Anesthesiologists can select the preferred endotracheal tube type and size best suited for the patient and procedure.

Endotracheal tube size will determine what size Dragonfly is needed. Dragonfly is available in multiple sizes and is compatible with a range of standard ET tubes. The sizing guide is as follows:

Dragonfly 1-Channel
LSE500MS fits 6 – 7 mm endotracheal tubes
LSE500M fits 7.5 - 10 mm endotracheal tubes

Dragonfly 2-Channel
LSE500DCS fits 6 – 7.5 mm endotracheal tubes
LSE500DCL fits 8 - 10 mm endotracheal tubes

Dragonfly EasyAim .5-Channel
LSE600MSP fits 2 – 5.5 mm endotracheal tubes
LSE600M fits 6 – 10 mm endotracheal tubes

EasyAim Dragonfly (LSE600MSP) is designed for 2 - 5.5 mm endotracheal tubes.

EasyAim is a .5-channel electrode and requires an external reference electrode (included) to create a single-channel device.

EasyAim is an EMG electrode designed for smaller-sized endotracheal tubes for patients with tiny airways.

The application is easy and the instructions for use give a step-by-step guide for proper attachment. The Dragonfly positioning stripes facilitate proper alignment during attachment.

Dragonfly is used in procedures where the recurrent laryngeal nerve (RLN) is at risk of injury, e.g., ACDF, parathyroidectomy, thyroidectomy, and skull base procedures.

The Dragonfly attaches to the endotracheal tube to easily integrate EMG monitoring on the devices that maintains an open airway during surgery.

Under normal circumstances, the Dragonfly will remain attached to the ET tube throughout the procedure. Therefore, it is essential to follow the Instructions For Use to attach the electrode and improve the overall performance.

No, Dragonfly electrodes are not made with Latex or any other potential allergens.

Dragonfly follows nerve monitoring EMG standards. The blue lead wire(s) corresponds to the electrode on the patient’s left, and the red lead wire(s) corresponds with the electrode on the patient’s right.

EasyAim Dragonfly can tolerate subtle rotation if needed and still maintain an EMG signal.

The 1-channel and 2-channel Dragonfly electrodes need to be secured in and maintain a midline position during the procedures for a reliable EMG signal. Rotation of the ET tube should be avoided.

With a Dragonfly securely attached to the endotracheal tube, intubation follows the current medical techniques with a Glidescope for visual confirmation of placement. Before securing the ET tube in place, connect the lead wires to the nerve monitoring system and conduct an impedance test. Once contact with the vocal cords is confirmed, secure the tube and repeat the impedance test.
