The manufacturer of disposable laryngeal mask airway catheter said that the laryngeal mask airway is an artificial airway often used in modern clinical emergency resuscitation and general anesthesia. It is mainly used to keep the airway unobstructed and ensure the ventilation and oxygenation of patients.

 

The laryngeal mask airway consists of two parts, the ventilation catheter and the ventilation mask. Ventilation catheter is similar to ordinary trachea. It is made of silica gel. One end of the ventilation catheter can be connected with anesthesia machine or ventilator. The other end is a ventilation mask. The ventilation mask forms an airway at the throat. The ventilation mask is made of soft rubber in an oval shape with a peripheral bulge. The inside is a cavity. At the connection between the ventilation catheter and the ventilation mask, the slope of the catheter cavity is 30 °, and the black line behind the ventilation catheter is helpful to identify the twist. There are two vertical fences on the upper part of the entrance of the ventilation catheter into the ventilation hood, which form several longitudinal fissures to prevent the epiglottis from blocking the lumen. The proximal end of the ventilation mask is connected with the gas injection tube, which can be inflated by injecting gas into the gas injection tube.

 

Disposable laryngeal mask airway catheter is actually an artificial airway that is mainly placed in the throat cavity, closed the esophagus and throat cavity with a balloon, and ventilated through the throat cavity. In this way, it will be very good to avoid tracheal intubation, but it is more effective than using a mask. Of course, its advantages during operation are also more based on its own characteristics and uses. Of course, if it is available, the laryngeal mask can be divided into four categories: ordinary laryngeal mask (used to maintain spontaneous breathing during anesthesia), reinforced laryngeal mask (used to control breathing), intubation laryngeal mask (assisted endotracheal intubation) and double lumen laryngeal mask. Of course, its products are mainly used for mechanical ventilation of eyes, nose, throat, skull and oral surgery.

 

Disposable laryngeal mask airway tubes can be autoclaved and reused. In addition, its advantages are also reflected in other places, such as no laryngoscope insertion, glottis exposure, glottis catheter inserted through the glottis and other mechanical stimulation, less prone to laryngeal edema, vocal cord injury, recurrent laryngeal nerve paralysis and other complications. If the disposable laryngeal mask airway catheter is inserted with light stimulation, less secretion and no influence on tracheal cilia activity, it will be very good for expectoration and can maintain the self-cleaning effect of airway. In this way, postoperative cough, atelectasis, pneumonia and other pulmonary complications are less. In addition, the product mentioned for everyone today is simple and easy to operate. As long as the patient has no difficulty in opening the mouth, the laryngeal mask can be inserted, and it is easy to fix and not easy to come out. It is suggested that everyone should fold or rotate the ventilation cover and overinflate the ventilation cover when using it. And its temperature rise or N2O dispersion increases the volume of the ventilation hood and closes the glottis.
