third generation of re-usable silicone LMA

New size: NO../ NO./ NO../ NO./ NO./ NO.

Clinical benefits:

  • Rapid, blind insertion (no laryngoscopy)
  • Allows single-handed ventilation
  • More secure than a face mask
  • hang Laryngeal Mask Airway with full line of pediatric sizes available
  • The re-useable Laryngeal Mask Airway is advantageous for the clean
  • The Laryngeal Mask Airway is advantageous for the bronchoscope insertion

The Laryngeal Mask Airway is made of medical-grade silicone rubber. IT has two kinds: for single use (with various of colours) and for re-useable. It consists of four main components: mask ,an airway tube,indicating ballonet and standard connector. The airway tube is a large-bore tube with a 15 mm standard connector and a fiberoptic scope. Its inserted end is fitted with a specially shaped cuff, which can be inflated and deflated via a valve on the end of the indicated cuff. The mask is designed to conform to the contours of the hypopharynx with its lumen facing the laryngeal opening.

Clinicians have successfully used the Laryngeal Mask Airway as a conduit for tracheal intubation, especially in the difficult airway situation. Therefore, if a patient who needs to insert a tube through the  Laryngeal Mask Airway is performed, using a fiberoptic scope will increase the likelihood of successful intubation. The single hole and mat finish designed for Laryngeal Mask Airway are advantageous for the insertion of Bronchoscope . The single hole Laryngeal Mask Airway is propitious to be cleaned, with no dead angle.Ideally, the Laryngeal Mask Airway should be considered as the proper option for blind intubation.

Tightly deflate the cuff so that it forms a smooth "spoon-shape" (Fig. 1). Lubricate the posterior surface of the mask with water-soluble lubricant.

Hold the Laryngeal Mask Airway like a pen, with the index finger placed at the junction of the cuff and the tube (Fig. 2).

With the head extended and the neck flexed, carefully flatten the Laryngeal Mask Airway tip against the hard palate (Fig. 3).

Use the index finger to push cranially, maintaining pressure on the tube with the finger. Note position of the wrist. Advance the mask until definite resistance is felt at the base of the hypopharynx (Fig. 4).

Gently maintain cranial pressure with the non-dominant hand while removing the index finger (Fig. 5).

Without holding the tube, inflate the cuff with just enough air to obtain a seal (to a pressure of approximately 60 cm H2O)(Fig. 6). Never overinflate the cuff.
