Background
Laryngeal mask ventilation is a novel supraglottic airway management device, and a patient cannot breathe spontaneously during emergency and anesthesia operations, so that an artificial ventilation tube can be quickly established through the laryngeal mask. Most of the existing inflatable laryngeal masks in the market use complicated laryngeal masks, air needs to be pumped during placement and inflated during sealing, and the air pressure of an air bag needs to be checked at regular time during the use; if the air is excessively filled, the pressure of the air bag is excessively high, so that the sealing effect is poor, the pressure of the throat is increased, and the capillary vessel and soft tissue of the throat can be damaged when the throat is pressed for a long time; at the same time, the continuous high pressure also produces flatulence and increases the risk of regurgitation and aspiration.
The inflation-free laryngeal mask used in the prior art has only two channels, namely one ventilation channel and one drainage channel, and if the patient has airway abnormality such as pulmonary effusion and airway spasm in the operation process, the patient needs to be inserted into a bronchoscope for examination or other instruments for treatment, and the existing laryngeal mask is not easy to treat, so that the operation difficulty is very high. The laryngeal mask inevitably generates secretion or reflux in the using process, the problem of laryngeal mask displacement in the operation process is also increased, meanwhile, the laryngeal mask without inflation is sealed by the structure of the laryngeal mask without the air bag, and the fault tolerance is smaller than that of the inflatable laryngeal mask, so that the position of the laryngeal mask is required to be adjusted frequently in the operation.
