DETAILED DESCRIPTION

[0022] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0023] like Figure 1-5As shown, the utility model provides a technical solution: a mouth-opening device fixing device, comprising a mask 1, both sides of the mask 1 are fixedly connected with elastic bands 2, the elastic bands 2 are hung on the ears, and the mask 1 can be worn on the patient's face by tightening the elastic bands 2, thereby preventing the mask 1 from falling off, both sides of the mask 1 are provided with ventilation holes 4, and the ventilation holes 4 can keep the mask 1 ventilated, thereby facilitating the patient's breathing, and the front side of the mask 1 is fixedly connected with a first elastic layer 3, the first elastic layer 3 is made of rubber material, the rubber material not only has elastic contractility, but also has softness, the first elastic layer 3 is in a trumpet shape, and the first elastic layer 3 is in a trumpet shape, so that the first elastic layer 3 is in a trumpet shape. The layer 3 can be folded to clamp the bite tube of the mouth opener with the first through hole 7, and the narrow end of the trumpet mouth is arranged forward to prevent the mouth opener from being moved due to thrust. A first through hole 7 is opened in the middle of the first elastic layer 3. The setting of the first through hole 7 facilitates the insertion of the bite tube of the mouth opener. The inside of the mask 1 is fixedly connected with a fixing plate 5, and a second elastic layer 8 corresponding to the first elastic layer 3 is fixedly connected to the fixing plate 5. The second elastic layer 8 is made of rubber and is in the shape of a trumpet. The trumpet mouth of the second elastic layer 8 contracts and closes the second through hole 9, so that the mouth opener can be fixed, and the narrow mouth of the trumpet mouth is arranged backward, so that the trumpet mouth can pre-tighten the bite tube of the mouth opener to prevent the mouth opener from generating In order to solve the problem of displacement, the second elastic layer 8 and the first elastic layer 3 are arranged with the horns opposite to each other, and a second through hole 9 is provided in the middle of the second elastic layer 8, through which the bite tube of the mouth opener can be conveniently inserted, so that the bite tube of the mouth opener can enter the patient's mouth, and a support structure 6 is inserted on the front side of the mask 1, and the support structure 6 includes a support sleeve 63, through which the smooth sliding of the connecting column 61 can be ensured, and the support sleeve 63 is fixedly connected to the mask 1, and the connecting column 61 is slidably connected inside the support sleeve 63, and the front end of the connecting column 61 is a raised ball, so as to provide a force point for medical staff, which is convenient for medical staff to operate the connecting column 61, and one end of the connecting column 61 is fixed A connecting plate 65 is connected, and a bucket ring 64 is fixedly connected to the end of the connecting plate 65. The connecting plate 65 is driven to move by pulling the connecting column 61, so that the connecting plate 65 drives the bucket ring 64 to smoothly open the first elastic layer 3, thereby facilitating the insertion of the mouth opener into the first through hole 7, avoiding the problem that the mouth opener is difficult to insert from the narrow end of the bell mouth. A spring 62 is fixedly connected to the connecting plate 65, and the elastic force of the spring 62 can push the connecting plate 65 to reset, so that the connecting plate 65 drives the bucket ring 64 to reset, and the bucket ring 64 is separated from the first elastic layer 3, so that the first elastic layer 3 can smoothly realize the operation of shrinking and tightening the mouth opener. One end of the spring 62 is fixedly connected to the support sleeve 63.

[0024] The number of the first through hole 7 and the second through hole 9 is one, preferably two, one group on each side; one group is suitable for adults and the other group is suitable for children; the two groups may also be of the same size for easy replacement.

[0025] The working principle of the utility model is:

[0026] When fixing the mouth opener, first wear the mask 1 on the patient's face, then fit the elastic band 2 on the ear, and then pull the connecting column 61 to make the connecting column 61 drive the connecting plate 65 to move, and make the connecting plate 65 drive the bucket ring 64 to move, so that the bucket ring 64 opens the first elastic layer 3, and the opening of the first through hole 7 can be enlarged, and then the mouth opener is inserted into the first through hole 7 and passes out through the bucket ring 64, and then passes out smoothly through the flared end of the trumpet of the second elastic layer 8, so that the bite tube of the mouth opener enters the patient's mouth, and the first elastic layer 3 and the second elastic layer 8 are elastically contracted, so that the first through hole 7 and the second through hole 9 are reduced to press against the bite tube of the mouth opener to complete the fixation.
