[0020] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] like Figure 1 、 Figure 2 As shown, a disposable medical laryngeal mask includes a cuff 1, a laryngeal tube 2 and an inflation tube 3, the inflation tube 3 is connected to the cuff 1, and also includes a bite component 5, the bite component 5 includes a bite plate 501 and a sleeve 502, the sleeve 502 is sleeved on the laryngeal tube 2, and the sleeve 502 is sequentially provided with a bite plate 501 and a baffle 505, the bite plate 501 is rotatably connected to the sleeve 502 through a rotating shaft 508, and the baffle 505 is set away from the cuff 1, and also includes a control device, which is used to control the tilt direction of the bite plate 501.

[0022] Before use, the bite plate 501 is adjusted to be tilted toward one end of the cuff 1, that is, the bite plate 501 forms an obtuse angle with the inflation tube 3 near one end of the cuff 1. During the process of inserting the laryngeal mask into the patient's mouth, the patient's teeth gradually approach the bite plate 501. Since the bite plate 501 is tilted, when the medical staff continues to insert the laryngeal mask, the patient's mouth gradually opens under the action of the tilted bite plate 501. After the patient's teeth pass through the rotating shaft 508, the bite plate 501 rotates around the rotating shaft 508, and the end of the bite plate 501 close to the cuff 1 is tilted, and the tilted end is placed in the patient's mouth. Without using the control device, the laryngeal mask will only move outward when the patient's mouth is opened again. At the same time, the baffle 505 is outside the patient's mouth to prevent the laryngeal mask from moving inward, thereby achieving fixation of the laryngeal mask.

[0023] The control component can be an air bag arranged on the side of the sleeve 502 at the end of the bite plate 501 away from the cuff 1. By inflating the air bag, the end of the bite plate 501 away from the cuff 1 can be lifted, and then the laryngeal mask can be smoothly removed from the patient's mouth. It should be noted that if this design is adopted, the initial state of the bite plate 501 should be tilted toward the end of the cuff 1, so that the patient's teeth can smoothly bite on the bite plate 501 when inserted.

[0024] During actual design, the bite plate 501 can be designed according to the curvature of the oral cavity, thereby improving the comfort of the patient.

[0025] In a specific embodiment, the bite plates 501 are provided in two groups and are symmetrically arranged about the axis of the sleeve 502 .

[0026] In actual use, the two sets of bite plates 501 correspond to the patient's upper teeth and lower teeth respectively, which is beneficial to improving the stability of the laryngeal mask and can prevent the throat 2 from being blocked by the patient's teeth during the operation, thereby reducing the risk of surgery.

[0027] In a specific embodiment, Figure 3 As shown, the control device includes a connecting rod 503, which is rotatably connected to the end of the bite plate 501 away from the cuff 1. A sliding groove 504 is provided on the sleeve 502, and a slider 509 is slidably connected in the sliding groove 504. The end of the connecting rod 503 away from the bite plate 501 is rotatably connected to the slider 509.

[0028] In actual use, the tilting direction of the bite plate 501 can be controlled by controlling the position of the slider 509 in the slide groove 504 .

[0029] In a specific embodiment, Figure 4 As shown, a first spring 510 is provided in the slide groove 504, one end of the first spring 510 is connected to the slider 509, and the other end is connected to the inner wall of the slide groove 504, the slider 509 is provided with a cavity 511 with an upper end open at one end away from the connecting rod 503, and a wedge block 513 is connected to the cavity 511 through a second spring 512, and a ring 514 is further provided on the sleeve 502, and a cavity 515 is provided in the ring 514, and a push plate 516 is provided in the cavity 515, and the push plate 516 is connected to a button 518 through a connecting column 517, and the button 518 is provided outside the ring 514, and a third spring 519 is provided on the end of the connecting column 517 close to the button 518.

[0030] During use, when the patient's teeth bite on the end of the bite plate 501 away from the cuff 1, the connecting rod 503 pushes the slider 509, so that the wedge 513 moves into the cavity 515. At this time, the first spring 510 is in a compressed state, so that the tilt direction of the bite plate 501 is fixed. When the laryngeal mask needs to be removed from the patient's mouth, just press the button 518, use the push plate 516 to push the wedge 513 and squeeze it into the cavity 511. The elastic force of the first spring 510 is released, and then the medical staff cooperates to pull out the laryngeal tube 2, so that the tilt direction of the bite plate 501 changes, so that the laryngeal mask can be smoothly removed from the patient's mouth.

[0031] In a specific embodiment, a limiting hole 506 is provided on the baffle 505 , and the inflation tube 3 is disposed in the limiting hole 506 .

[0032] In a specific embodiment, the sleeve 502 is threadedly connected to the throat pipe 2 .

[0033] In actual use, since the lengths of the oral cavity of different patients are different, the occlusal position needs to be adjusted. By threading the control sleeve 502 to the throat tube 2, the position of the sleeve 502 can be adjusted according to actual conditions.

[0034] In a specific embodiment, the end of the bite plate 501 close to the cuff 1 is configured as a curved surface.

[0035] Principle of use: Under normal circumstances, the bite plate 501 is in a state of being tilted toward the cuff 1. When the medical staff inserts the laryngeal mask into the patient's mouth, as the laryngeal mask goes deeper, the patient's teeth gradually come into contact with the bite plate 501. The setting of the arc surface allows the patient to bite smoothly on the bite plate 501. When the patient's teeth pass through the rotating shaft 508, the bite plate 501 rotates around the rotating shaft 508. One end of the bite plate 501 close to the cuff 1 is tilted, and the other end pushes the slider 509 through the connecting rod 503, so that the wedge block 513 moves into the cavity 515. At this time, the first spring 510 is in a compressed state. , to achieve the fixation of the state of the bite plate 501, to prevent the laryngeal mask from moving out of the oral cavity, the baffle 505 is outside the oral cavity, which can prevent the laryngeal mask from moving into the oral cavity, thereby achieving the fixation of the laryngeal mask. When the laryngeal mask is fixed, the inflatable airbag 4 is used to inflate the cuff 1, which is convenient for subsequent operations. When the laryngeal mask needs to be removed, the button 518 is pressed, and the push plate 516 is used to push the wedge 513 and squeeze it into the cavity 511. The elastic force of the first spring 510 is released, and then the medical staff cooperates with the laryngeal tube 2 to pull out, so that the tilt direction of the bite plate 501 changes, so that the laryngeal mask can be smoothly taken out of the patient's mouth;

[0036] This setting can avoid the use of straps to fix the laryngeal mask, which not only improves the stability of the laryngeal mask, but also reduces the patient's discomfort. At the same time, through the threaded connection between the sleeve 502 and the laryngeal tube 2, the occlusal position can be controlled in real time, which is more practical.

[0037] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the scope of the present invention, all of which fall within the scope of protection of the present invention.
