Reinforced Silicone Laryngeal Mask Airway

Effect of the insertion position and angle of the reinforced silicone laryngeal mask airway on sealing
Ningbo Yuxin Medical Instruments Co., Ltd. is a high-tech enterprise specializing in the production of anesthesia respiratory consumables and gynecological products. The reinforced silicone laryngeal mask airway produced by it has a wide range of applications in the medical field. The design of the reinforced silicone laryngeal mask airway is specifically designed to solve the problem that the standard laryngeal mask airway tube may interfere with the surgical area, and is suitable for various head and neck positions. Compared with the traditional laryngeal mask, the reinforced silicone laryngeal mask uses a soft flexible metal tube to replace the semi-rigid airway tube while maintaining the same performance in all aspects, thus giving it greater flexibility and pressure resistance.
Effect of insertion position on sealing
The insertion position of the reinforced silicone laryngeal mask is one of the key factors affecting its sealing performance. The correct insertion position can ensure that the laryngeal mask fits the patient's laryngeal structure closely, thereby effectively preventing gas leakage.
Front end position of the laryngeal mask: The front end of the laryngeal mask should be located above the glottis to ensure that the gas can enter the trachea smoothly while avoiding compression of the glottis. If the front end of the laryngeal mask is too low, it may enter the trachea, causing airway obstruction or air leakage; if the position is too high, it may not be able to fully cover the glottis, causing air leakage.
Position of the side wings of the laryngeal mask: The side wings of the laryngeal mask should be close to both sides of the epiglottis to form an effective seal. If the side wings are not positioned correctly, such as too wide or too narrow, it may cause air leakage. Therefore, when inserting the laryngeal mask, make sure that the side wings match the patient's laryngeal structure to achieve the best sealing effect.
Depth of the laryngeal mask: The depth of the laryngeal mask is also an important factor affecting the sealing. Too deep insertion may cause the front end of the laryngeal mask to enter the esophagus or trachea, causing air leakage or aspiration; too shallow insertion may not be able to fully cover the glottis, also causing air leakage. Therefore, when inserting the laryngeal mask, the depth of the laryngeal mask should be adjusted according to the patient's specific situation and surgical needs to ensure the best sealing effect.
2. The impact of the insertion angle on the sealing
In addition to the insertion position, the insertion angle is also one of the key factors affecting the sealing performance of the reinforced silicone laryngeal mask. The correct insertion angle can ensure that the laryngeal mask matches the patient's laryngeal structure to form an effective seal.
Head and neck position: When inserting the laryngeal mask, the patient's head and neck position has an important impact on the sealing performance of the laryngeal mask. Generally, the patient's head should be tilted back slightly to better expose the glottis and laryngeal structure. If the head position is too low or too high, the laryngeal mask may not be inserted correctly or the sealing effect may be poor.
Relationship between the laryngeal mask and the tongue root: The insertion angle of the laryngeal mask should ensure that it maintains an appropriate distance from the tongue root to avoid compression or damage to the tongue root. If the laryngeal mask is too close to the tongue root, it may cause the tongue root to fall back, thereby increasing the risk of airway obstruction; if it is too far, an effective seal may not be formed. Therefore, when inserting the laryngeal mask, the insertion angle of the laryngeal mask should be adjusted according to the patient's tongue root position and size to ensure the best sealing effect.
Relationship between the laryngeal mask and the laryngeal structure: The insertion angle of the laryngeal mask should also take into account the characteristics of the patient's laryngeal structure. For example, for patients with narrow or wide larynx, the insertion angle of the laryngeal mask should be appropriately adjusted to ensure that it matches the laryngeal structure. In addition, for patients with laryngeal lesions or a history of surgery, the insertion angle should be chosen with caution to avoid further damage to the larynx.
