Disposable Double-Lumen Endobronchial Tubes

The disposable double-lumen endobronchial tube (DLT) is a special endotracheal intubation device used to achieve single-lung ventilation in The disposable double-lumen endobronchial tube (DLT) is a special endotracheal intubation device used to achieve single-lung ventilation in thoracic surgery. It is designed to separate the left and right main bronchi, allowing one lung to be ventilated while the other lung is collapsed, thereby providing a clear field of view for surgery and ensuring the patient's breathing safety. This product is widely used in thoracoscopic surgery, lobectomy, and complex thoracic surgery requiring single-lung ventilation.

Structure and design

Dual-chamber structure

Main tracheal cavity: connected to the ventilator, responsible for ventilation.

Bronchial cavity: inserted into the target bronchus (left or right), fixed and isolated by the cuff.

Cuff system:

Tracheal cuff (off-white inflation tube): located at the end of the main tracheal cavity, fixes the position of the catheter.

Bronchial cuff (orange-red inflation tube): ensures bronchial sealing and prevents gas leakage613.

X-ray marking ring: facilitates intraoperative positioning confirmation6.

Material and coating

Material: mostly natural rubber or medical-grade PVC, some imported products use silicone material (such as Fuji Silbroncho catheter), which has better flexibility and biocompatibility612.

Surface coating: SILKOLATEX® coating reduces friction and reduces the risk of intubation injury6.

Product features

Efficient lung isolation

The cuff has strong sealing after inflation, ensuring rapid collapse of the unilateral lung and providing a stable surgical field of view111.

Easy to operate

Some models (such as VivaSight-DL) have built-in cameras to monitor the position of the catheter in real time and reduce the reliance on fiberoptic bronchoscope positioning

Safety optimization

The thin-walled cuff design (such as PU material) reduces airway mucosal pressure and reduces the risk of ischemic injury

Wide range of indications

Applicable to endobronchial anesthesia, single-lung ventilation examination and thoracic surgery, especially for patients with difficult airways, visual laryngoscope-assisted intubation
