The ventilation mask at the front end of the laryngeal mask is oval in shape, which can wrap around the epiglottis and glottis, forming a sealed ventilation space on the glottis. The patient can breathe independently through the laryngeal mask. It is widely used in patients with general anesthesia, patients undergoing emergency treatment and resuscitation in the emergency department, ICU and various departments, and in difficult airway.

[0003] A search revealed Chinese patent document CN219481173U, which discloses a medical laryngeal mask that is easy to fix. The mask is provided with a bite ring to prevent the patient's teeth from squeezing the trachea. The bite ring abuts against the patient's teeth, thereby fixing the entire device. This achieves convenient fixation of the mask and prevents the patient from biting the trachea and causing blockage. However, the following defects still exist:

[0004] When the above-mentioned medical laryngeal mask that is easy to fix is ​​used, due to the different ages of patients, the different positions and curvatures of teeth in the oral cavity, the existing bite ring cannot fit the tooth surfaces of different patients for fixation, resulting in loosening during fixation.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] See also Figure 1-5 The utility model provides a medical laryngeal mask that is easy to fix, including an airway tube 1, a connecting tube 101, an air bag 2, an inflation tube 201, an air valve 202, a support tube 3, a limiting ring 301, a limiting slide 302, a lower connecting ring 4, a lower adjusting ring 401, a lower rotating shaft 402, a first connecting block 403, a lower bite block 404, a first limiting slider 405, an upper connecting ring 5, an upper adjusting ring 501, an upper rotating shaft 502, a second connecting block 503, an upper bite block 504, a second limiting slider 505, and an elastic bite piece. 6. One end of the air guide tube 1 is connected to the airbag 2, and the side of the airbag 2 close to the air guide tube 1 is connected to the inflation tube 201. The end of the inflation tube 201 away from the airbag 2 is provided with an air valve 202. The end of the air guide tube 1 away from the airbag 2 is connected to the connecting tube 101. The surface of the connecting tube 101 is fixed with a support tube 3, and the surface of the support tube 3 is a threaded structure. The upper and lower ends of the support tube 3 are fixed with a circular ring structure. The limiting ring 301 can prevent the lower connecting ring 4 and the upper connecting ring 5 from detaching from the support tube 3.

[0024] The surface of the support tube 3 is provided with a lower connecting ring 4 and an upper connecting ring 5 of a circular ring structure with the same shape and size. Two groups of first limiting sliders 405 are fixed on the inner side of the lower connecting ring 4, and a limiting slot 302 is provided at the connection between the two groups of first limiting sliders 405 and the surface of the support tube 3. The top of the lower connecting ring 4 is rotatably connected to the lower adjusting ring 401, and the lower adjusting ring 401 is threadedly connected to the support tube 3. A lower rotating shaft 402 is fixed to the top of the lower connecting ring 4 near the lower adjusting ring 401, and the lower adjusting ring 401 is connected to the lower connecting ring through the lower rotating shaft 402. The ring 4 is rotatably connected, so that the rotation of the lower adjustment ring 401 can adjust the position of the lower connecting ring 4, making it convenient for the lower bite block 404 and the elastic bite piece 6 on the lower connecting ring 4 to fit the inner side of the teeth. Two groups of first connecting blocks 403 are symmetrically fixed on the side of the lower connecting ring 4. The end of the first connecting block 403 away from the lower connecting ring 4 is connected to the lower bite block 404 with a surface covered with silicone material. The silicone material of the lower bite block 404 is softer when connected to the teeth, reducing discomfort, and the upper connecting ring 5 is arranged above the lower connecting ring 4.

[0025] The second connecting block 503 is fixed on both sides of the upper connecting ring 5, and the second connecting block 503 is fixed on the side away from the upper connecting ring 5 with an upper bite block 504 covered with silicone material on the surface. This makes it convenient for the upper bite block 504 to be connected to the teeth and avoids damage to the gums.

[0026] The thickness of the second connecting block 503 is greater than that of the upper bite block 504, and the thickness of the first connecting block 403 is greater than that of the lower bite block 404. In this way, the sides of the second connecting block 503 and the first connecting block 403 can block the front part of the teeth, making it easier to clamp the teeth. Elastic bite pieces 6 made of silicone material are fixed on both sides of the upper bite block 504 and the lower bite block 404, and the tops of the elastic bite pieces 6 on both sides of the lower bite block 404 are flush with the top of the lower bite block 404, and the bottoms of the elastic bite pieces 6 on both sides of the upper bite block 504 are flush with the bottom of the upper bite block 504, which can fit the surface of the teeth better and be fixed to the surface of the teeth.

[0027] When the embodiment of the present application is in use: by setting the lower connecting ring 4 and the upper connecting ring 5 with adjustable positions, when the air bag 2 is inserted into the throat tube, the position can be adjusted so that the lower bite block 404 and the upper bite block 504 are clamped on the upper and lower sides of the patient's teeth. When adjusting, the lower adjusting ring 401 is rotated. When the lower adjusting ring 401 rotates, it can move on the support tube 3 through the connected threaded structure, and the lower connecting ring 4 is driven by the lower rotating shaft 402 to push it close to the inner side of the replaced tooth. At this time, the first limiting slider 405 on the lower connecting ring 4 can prevent the lower connecting ring 4 from rotating, and when driving the lower bite block 404 to move upward, the elastic bite pieces 6 on both sides of the lower bite block 404 will also fit the inner side of the tooth, and then the upper adjusting ring 501 is rotated, and the upper adjusting ring 501 can drive the upper connecting ring 5 to move downward, and the downward movement of the upper connecting ring 5 will drive the upper bite block 504 and the elastic bite piece 6 to move downward. 04 and the lower bite block 404 are clamped on both sides of the teeth, so that the device can be fixed through the teeth, avoiding the shaking of the airway 1, and the lower bite block 404 and the upper bite block 504 can be adjusted separately, which is convenient for adapting to the tooth shape and tooth thickness of different patients.
