Laryngeal Tube LTS-D

The 2nd generation
supraglottic airway device

Easy insertion

Reduction of aerosol spread

Atraumatic for patients

Efficient ventilation

The Laryngeal Tube LTS-D is a 2nd generation supraglottic airway (with drain tube) and an alternative adjunct to temporarily secure the airway during emergency situations, e.g. cardiopulmonary resuscitation, in hospital as well as prehospital environments.



Multiple ventilation outlets for efficient ventilation


Drain tube to prevent the risk of aspiration


Thin walled cuffs allow maximum airway leak pressure and reduce the spread of aerosol thanks to efficient pharyngeal sealing. This is achieved at low cuff pressure (<60 cmH20) making the LTS-D atraumatic to the mucosa.


Teeth mark as indicator for correct depth of insertion

Easy Insertion

The LTS-D is easy to insert and use, even with minimal training (1). In situations with limited space or in patients with minimal mouth opening the slim design of the laryngeal tube facilitates insertion (2). The teeth mark is an indicator regarding the correct depth of insertion and for orientation and repositioning purposes.

Drain Tube / Gastric Tube

  • Drain tube recommended as current standard in international guidelines. All LTS-D sizes include the drain tube as standard
  • Providing the largest suction capability with easy access can accomodate up to 18 Fr gastric tube
  • Insertion of a gastric tube is helpful to confirm correct placement of the LTS-D

Colour Coding

The colour coded system has proven invaluable in emergencies as the syringe and connectors indicate the recommended maximum inflation volume.

——Clinical Features

Exchange of LTS-D for Tracheal Tube

Possibility of exchanging the LTS-D (in situ with deflated cuffs) for a Tracheal Tube using Video Laryngoscopy and a Bougie.

Reduction of Aerosol Spread (3)

The application of the LTS-D in combination with a breathing system filter leads to a remarkable reduction of aerosol spread during aerosol generating procedures (AGP) e. g. chest compressions.

Easy to insert especially in cases of cardiac arrest without interruption of chest compressions. This leads to significant reduction in no-flow-time (4).

Uninterrupted Chest Compressions
Due to a very high airway leak pressure, uninterrupted chest compressions during CPR are possible.

Higher Survival

(Higher 72-hour survival in adults with OHCA (LTS-D compared to ETI) (5).
