The endoscopic laryngeal mask is usually made of soft medical materials such as rubber or plastic. It is a tubular structure sleeved outside the endoscope. One end is connected to the endoscope control rod, and the other end is used to cover and protect the patient's oral cavity and pharynx. The endoscopic laryngeal mask can conveniently operate the endoscope through the control rod, enabling doctors to accurately observe and examine the lesions in the oral cavity and pharynx. The endoscopic laryngeal mask is widely used in endoscopic examinations, especially for diseases that require further examination of parts such as the oral cavity and throat, such as oral ulcers, vocal cord polyps, and laryngeal cancer. In addition, the endoscopic laryngeal mask is also commonly used for removing foreign bodies, performing vocal cord examinations, sampling, or performing surgical operations.

[0021] Please refer to Figures 1 to 4 , in this practical embodiment, an endoscope diagnostic laryngeal mask includes a laryngeal mask tube body 1, whose internal channel is used to insert an endoscope to protect the oral cavity and esophagus. The outer side wall of the lower end of the laryngeal mask tube body 1 is fixedly connected with a mask bladder 2. The upper side of the mask bladder 2 is communicated with an inflation tube 3. The mask bladder 2 is inflated and collided by the inflation tube 3, and the device can be fixed on the inner wall of the patient's esophagus. An air pressure monitoring gauge 4 is arranged on the inflation tube 3. The air pressure monitoring gauge 4 can monitor the air pressure in the mask bladder 2 to prevent excessive air pressure from causing damage to the patient's esophagus and improve protection. A ventilation tube 5 is inserted through the side wall of the mask bladder 2 to maintain ventilation with the patient's trachea. A heating mechanism is fixedly connected to the outer side wall of the laryngeal mask tube body 1, and one end of the heating mechanism penetrates into the mask bladder 2;

[0022] The heating mechanism includes a water inlet valve tube 6 located on one side of the laryngeal mask tube body 1. One end of the water inlet valve tube 6 penetrates into the mask bladder 2 and is communicated with a spiral heating water pipe 7. The spiral heating water pipe 7 is sleeved on the outer side walls of the laryngeal mask tube body 1 and the ventilation tube 5. One end of the spiral heating water pipe 7 away from the water inlet valve tube 6 is communicated with a water outlet valve tube 8. One end of the water outlet valve tube 8 penetrates to the outside of the mask bladder 2. The water inlet valve tube 6 is externally connected to a circulating hot water device. Hot water is introduced into the spiral heating water pipe 7 from the water inlet valve tube 6, and the laryngeal mask tube body 1 can be heated. The temperature can be maintained at about 38 degrees Celsius. Then, the hot water flows back to the circulating hot water device through the water outlet valve tube 8, avoiding being too cold in winter and improving the comfort of this device.

[0023] As Figure 1 shown: The outer side wall of the laryngeal mask tube body 1 is fixedly connected to the side walls of the inflation tube 3, the ventilation tube 5, the water inlet valve tube 6 and the water outlet valve tube 8 to prevent the offset of each pipeline.

[0024] As Figure 3 shown: The lower end of the laryngeal mask tube body 1 is arranged in a wedge-shaped structure, which is convenient for inserting into the laryngeal tube. One side of the opening at the lower end of the laryngeal mask tube body 1 is movably connected with a check valve piece 10 through a memory spring piece 9. The memory spring piece 9 can be made of elastic materials such as rubber. When the endoscope passes through the outlet end of the laryngeal mask tube body 1, the memory spring piece 9 can be pushed to swing and closely adhere to the inner wall of the esophagus. When the endoscope is taken out, the characteristic of the memory spring piece 9 is used to drive the check valve piece 10 to reset and block the lower end of the laryngeal mask tube body 1, thereby preventing the backflow of materials in the esophagus.

[0025] As Figure 2As shown in the figure: A limiting ring plate 11 is fixedly connected to the outer side wall of the upper end of the laryngeal mask tube body 1. A first avoidance groove 12 corresponding to the inflation tube 3 is provided on the side wall of the limiting ring plate 11. The ventilation tube 5 penetrates through the limiting ring plate 11. A second avoidance groove 13 corresponding to the water inlet valve tube 6 and the water outlet valve tube 8 is provided on the side wall of the limiting ring plate 11, which is convenient for tube threading and has a limiting effect on the pipeline, preventing excessive deviation.

[0026] As Figure 2 shown in the figure: A one-way valve 14 is provided at one end of the inflation tube 3 away from the cuff 2 to prevent air leakage from the cuff 2.

[0027] As Figure 3 shown in the figure: A spherical ventilation head 15 is fixedly connected to one end of the ventilation tube 5 passing through the cuff 2, and the ventilation effect is good.

[0028] Working principle: When using this device, the laryngeal mask tube body 1 is inserted into the esophagus from the oral cavity, and the cuff 2 is inflated through the inflation tube 3, so that the device can be fixed on the inner wall of the patient's esophagus. The air pressure monitoring table 4 can monitor the air pressure in the cuff 2 to prevent excessive air pressure from causing damage to the patient's esophagus and improve protection. Secondly, the water inlet valve tube 6 is externally connected to a circulating hot water device, and hot water is introduced into the spiral heating water pipe 7 through the water inlet valve tube 6 to heat the laryngeal mask tube body 1, and the temperature can be maintained at about 38 degrees Celsius. Then, the hot water flows back to the circulating hot water device through the water outlet valve tube 8 to avoid being too cold in winter and improve the comfort of this device. Secondly, when the endoscope passes through the outlet end of the laryngeal mask tube body 1, the memory elastic piece 9 can be pushed to swing and closely adhere to the inner wall of the esophagus. When the endoscope is taken out, the characteristic of the memory elastic piece 9 is used to drive the check valve piece 10 to reset and block the lower end of the laryngeal mask tube body 1, thereby preventing the backflow of materials in the esophagus.
