It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-4, an adjustable mouth gag includes:

the rectangular box 1 is hollow, sawtooth holes 10 are formed in the left side wall and the right side wall of the rectangular box 1, and vertical holes 11 are formed in the front side wall of the rectangular box;

the operating part 2 comprises a box body 20, an adjusting component 21 and two groups of adjusting handles 22, the adjusting handles 22 penetrate through the sawtooth-shaped holes 10 and are fixedly connected to the two ends of the box body 20, two strip-shaped holes 200 are formed in the upper end of the box body 20, and the adjusting component 21 is movably connected to the inner sides of the strip-shaped holes 200;

the occlusion part 3 comprises an occlusion piece 30 and a rectangular rod 31 which are fixedly connected, and the rectangular rod 31 penetrates through the strip-shaped hole 200 and is fixedly connected with the adjusting component 21.

When the device is used specifically, the position of the adjusting handle 22 is adjusted, so that the adjusting handles 22 at the two ends of the rectangular box 1 are adjusted to the grooves at the bottom sides of the saw-tooth-shaped holes 10, the position of the adjusting assembly 21 is adjusted to the lowest, then the rotating handle 210 is screwed, so that the two bite plates 30 are close to the middle position of the box body 20, after the adjustment is completed, the two bite plates 30 are put into the oral cavity of a patient, so that the teeth of the patient are positioned in the bite grooves 301 on the bite plates 30, then the chin buckle 12 is buckled on the chin of the patient for strengthening and fixing, then the rotating handle 210 is screwed, the rotating teeth 211 are driven to rotate by the rotation of the rotating handle 210, then the relative movement of the toothed plates 212 is driven by the meshing of the rotating teeth 211 and the toothed plates 212, so that the two toothed plates 212 are far away from each other, the oral cavity of the patient is enlarged, after the proper adjustment is completed, the height of the operating part 2 can be adjusted, and the chin buckle 12 and the chin of the patient, the position of the rectangular box 1 is fixed, the position of the regulating handle 22 in the sawtooth-shaped hole 10 is different, the vertical height of the operating part 2 in the rectangular box 1 is also different, and then the adjustment of the size of the oral cavity of the patient is achieved, and in the process of intubating the patient, the saliva generated by the oral cavity of the patient falls on the saliva bag 32 and then is discharged through the delivery pipe 320.

Specifically, the adjusting assembly 21 includes a rotating handle 210, a rotating tooth 211 and two toothed plates 212, the rotating handle 210 passes through the vertical hole 11 and is fixedly connected with the rotating tooth 211, the rectangular rod 31 passes through two bar holes 200 respectively and is fixedly connected to two ends of the toothed plates 212, and the toothed plates 212 are in meshed connection with the rotating tooth 211.

The rotation of the rotating teeth 211 is driven by the rotation of the rotating handle 210, the two toothed plates 212 are driven to move in opposite directions by the meshing of the rotating teeth 211 and the toothed plates 212, and then the oral cavity is enlarged and reduced by the toothed plates 212.

Specifically, the biting sheet 30 is arc-shaped, the inner side of the biting sheet is made of plastic material, the outer side of the biting sheet is made of silica gel material, and the middle position of the outer side of the biting sheet is provided with a biting groove 301; the inboard plastics material that adopts of bite piece 30 has certain hardness, can not make it take place big deformation and then lead to going out of effect because of the interlock of patient's mouth, and the outside because with the contact of patient oral cavity portion, the soft speciality of silica gel material makes bite piece 30 can not bring too big discomfort for the patient, and the setting up of bite groove 301 can effectively guarantee that the patient can be propped open by bite piece 30 and the condition that bite piece 30 received the extrusion and was spit out can not appear and take place.

Specifically, a chin buckle 12 fixedly connected with the rectangular box 1 is arranged at the lower end of the rectangular box 1, a plurality of connecting ropes 13 are fixedly connected to two ends of the bottom wall of the rectangular box 1, and the connecting ropes 13 are fixedly connected with the chin buckle 12; the chin bar 12 is arranged to hold the rectangular box 1 by its force applied to both ends of the bite piece 30.

Specifically, the engaging part 3 is further provided with a mouth water bag 32, and two ends of the mouth water bag 32 are respectively detachably connected to the lower ends of the two engaging pieces 30;

specifically, the saliva bag 32 is made of an elastic film material, and is provided with a delivery pipe 320 integrally connected with the saliva bag; when patient's oral cavity was strutted, produced saliva and belonged to the natural reaction, and the patient is inconvenient again to be spit out oral cavity under the condition of strutting the oral cavity, and the existence of saliva bag 32 can collect most saliva and outside the drainage oral cavity via delivery tube 320, makes things convenient for medical staff's further operation, reduces patient's uncomfortable simultaneously and feels.

Specifically, the length of the toothed plate 212 is greater than half of the length of the box body 20; the limitation of the length of the toothed plate 212 enables it to move to the top of the bar-shaped hole 200, while ensuring that it does not disengage from the rotating teeth 211.

The present invention has been further described with reference to the embodiments, but the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge of those skilled in the art.
