reusable laryngeal mask airway

Laryngeal mask has many advantages: (1) it is easy to use and can quickly establish artificial airway; (2) The success rate of placement was high. The success rate of untrained medical staff was 87%, and the total success rate was 99.81%; (3) Reliable ventilation; (4) Avoid injury of throat and tracheal mucosa; (5) Small stimulation and cardiovascular response; (6) It can be used for first aid.

A laryngeal mask airway (LMA) — also known as laryngeal mask— is a medical device that keeps a patient's airway open during anaesthesia or unconsciousness. It is a type of supraglottic airway. A laryngeal mask is composed of an airway tube that connects to an elliptical mask with a cuff which is inserted through the patient's mouth, down the windpipe, and once deployed forms an airtight seal on top the glottis (unlike tracheal tubes which pass through the glottis) allowing a secure airway to be managed by a health care provider. Reusable Reinforced LMA is equipped with a stainless steel spring to prevent the airway to be kinked during insertion.
