Description

Auxiliary device is put into to laryngeal mask

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to auxiliary device is put into to laryngeal mask.

Background

The laryngeal mask is widely applied to clinical airway management at present as an supraglottic ventilation device. The patient is greatly reduced in irritation because the laryngeal mask airway device does not require contact with the sensitive internal passages of the trachea, nor does it require the use of a laryngoscope. Meanwhile, the laryngeal mask has small operation actions on the head, the neck and the like of a patient when being inserted, so that the laryngeal mask can be successfully used for a patient with difficult intubation. The laryngeal mask is not inserted into the trachea, does not contact the vocal cords, and does not cause mechanical damage to the vocal cords and the trachea like a tracheal cannula. The postoperative patient has quick waking, no intubation general anesthesia and waking, drowsiness or dysphoria, no pain and memory in the whole process, and less complications such as nausea, vomiting, throat discomfort and the like.

When the laryngeal mask is used, the laryngeal mask is generally directly sent into the oral cavity of a patient by holding the laryngeal mask with fingers, and the laryngeal mask is pushed by force to sequentially enter the laryngeal part of the pharynx until the laryngeal mask reaches the position of an epiglottis. Although this method is simple, there may be problems in the insertion of the laryngeal mask: 1. the laryngeal mask has a certain volume, is influenced by the mouth opening degree of a patient when entering the oral cavity, often needs to be opened by hands, and is easily blocked by incisors when being placed; 2. when the laryngeal mask is pushed towards the throat in the mouth, the pushing resistance is increased or the laryngeal mask is deviated due to limited oral space and the influence of the tongue body; 3. when the tip of the laryngeal mask reaches the posterior pharyngeal wall, the tip of the laryngeal mask is easy to bend due to the physiological bending of the laryngeal part of the pharynx, when the pushing pressure is too high, the posterior pharyngeal wall can be bleeding and damaged, and hematoma can be generated partially. Clinically convenient placement may reduce this physiological curvature by tilting the cervical spine backwards, which is a dangerous maneuver for some patients who may have problems with the cervical spine.

Therefore, it is a considerable problem to provide a laryngeal mask insertion aid that facilitates the opening of the upper incisors and maintains the degree of opening.
