Description

Technical Field

[0001] The utility model relates to the technical field of laryngeal mask production, in particular to automated equipment for laryngeal mask gluing. Background Art

[0002] Laryngeal mask, full name laryngeal mask airway (LMA), is an artificial airway placed in the throat cavity, using an air bag to seal the esophagus and throat cavity, and ventilating through the throat cavity, avoiding tracheal intubation, but more effective than using a mask. The reinforced laryngeal mask is an upgraded product of the traditional single-chamber laryngeal mask. It consists of a cuff, airway, inflation tube, check valve, etc. Unlike the traditional laryngeal mask, the reinforced laryngeal mask has an additional compression spring-shaped reinforcement rib in the airway channel. The ventilation tube of the reinforced laryngeal mask with the reinforcement spring is soft, flexible and bendable. Compared with ordinary laryngeal masks, the ventilation channel is not easy to angle, thereby reducing the risk of airway blockage. During the production process of the laryngeal mask, in order to ensure the subsequent processing and use, the laryngeal mask and the mask bag need to be coated with glue to bond them together;

[0003] The bonding surface between the disposable laryngeal mask airway tube and the mask bag in the existing technology is an irregular elliptical surface. During production, a manual gluing process is generally adopted, which is labor-intensive. Since the gluing of the laryngeal mask airway tube may be shaken by hand, the gluing may be uneven, which reduces the production qualification rate. Therefore, we need to propose an automated equipment for gluing the laryngeal mask. Utility Model Content
