Cuffed Laryngeal Mask Airway,
Laryngeal Mask Airway Nontoxic,
Transparent Cuffed Oropharyngeal Airway
Laryngeal Mask Airway(Single Use PVC)
A laryngeal mask enables anaesthetists to channel oxygen or anaesthesia gas to a patient's lungs during surgery. It has an airway tube that connects to an elliptical mask with a cuff. When the cuff is inflated, the mask conforms to the anatomy with the bowl of the mask facing the space between the vocal cords. After correct insertion, the tip of the laryngeal mask sits in the throat against the muscular valve that is located at the upper portion of the oesophagus.
1. For short term surgery use;
2. Easy operation and less trauma caused to patients;
3. No need laryngoscope;
4. Paper-plastic Peer pouch packing;
5. CE, ISO 13485 approved.
Indications for laryngeal mask
1. For surgeries without the risk of vomiting or reflux. LMA is an alternative ventilation method for mask ventilation and endotracheal intubation ventilation, but if there is an indication for endotracheal intubation, LMA cannot replace endotracheal intubation ventilation.
2. During emergency resuscitation (CRP), the placement of a laryngeal mask is relatively simple, convenient to use, reliable in effect, and can save precious time.
3. LMA is used to handle difficult airways that are known or difficult to predict.
Principle of Laryngeal Mask Placement
The insertion principle of laryngeal mask is similar to the mechanism of swallowing. At the beginning of swallowing, the food ball wrapped in saliva is compressed by the tongue to the hard palate, forming a flat oval shaped food ball. Then the tongue pushes it up and back towards the entrance of the oropharynx, and through the coordinated movement of the oropharynx muscles, it enters the opening of the upper esophageal sphincter.
When the food ball is pushed between the oral cavity and the oropharynx, the soft palate becomes hard to prevent nasopharyngeal reflux and guide the food ball to move downward. When passing between the oropharynx and esophagus, movements such as pushing the food ball backwards, raising the glottis when the food ball passes, closing the glottis entrance, and covering the glottis with the epiglottis are used to prevent inhalation of food.
The neck is slightly bent, the head is slightly extended, and the mouth is closer to the pharyngeal cavity to form a straight line, further helping the food ball enter the pharynx from the mouth.
The similarities between laryngeal mask placement and swallowing include:
The shape of the food ball and the ventilation hood for air release are both flat and elliptical; Saliva and water-soluble lubricants cover the surface of the food ball and laryngeal mask respectively, reducing frictional movement through the mucosa; The tongue and fingers respectively push the food ball and laryngeal mask upwards against the hard palate, and move downwards along the palatopharyngeal curve to reduce insertion into the anterior pharyngeal structure; The position of the head and neck is the same, both presenting olfactory positions; Both the food ball and the laryngeal mask enter the lower pharynx.
