Description

Auxiliary device for laryngeal mask placement Technical Field The invention relates to the technical field of medical appliances, in particular to an auxiliary device for laryngeal mask placement. Background The laryngeal mask belongs to an artificial airway medical device, and comprises a ventilation mask and a ventilation tube, wherein the ventilation mask is placed in a pharyngeal cavity and can seal the periphery of the larynx, so that gas is prevented from leaking out of the ventilation mask and secretion in the pharyngeal cavity from entering the laryngeal cavity. The ventilation tube of the laryngeal mask communicates with the mask to supply air to the mask and to maintain the patient's breathing. The flexible and bendable nature of the laryngeal mask airway prevents the laryngeal mask from being pushed into the pharyngeal cavity via the airway, and instead requires the manipulation of the bendable laryngeal mask by the fingers in combination with specific manipulations, which is inconvenient. Particularly, when the bendable laryngeal mask is used for infants, the bendable laryngeal mask is easy to exceed the opening degree of the infants by finger operation, so that the bendable laryngeal mask is difficult to put in, the center of the ventilation mask of the laryngeal mask is recessed, the tongue body often enters the recess of the ventilation mask in the process of putting the ventilation mask into a pharyngeal cavity, so that the friction force is increased in the process of putting the ventilation mask, and the operation is inconvenient.
