Description

Temporomandibular joint injury is with ware of opening one's mouth

Technical Field

The utility model belongs to the technical field of mechanical equipment and specifically relates to a temporomandibular joint is gag for damage.

Background

Many times people need to prop open the closed upper and lower objects, and a pry bar is used under most conditions. The pry bar is relatively coarse and violent, and when the upper and lower objects are relatively soft or the pry bar is inconvenient to use, a method that the upper and lower objects are more gentle and more difficult to damage needs to be adopted. After the upper and lower objects are opened, how to fix the opening angle is also needed to be considered. In conclusion, the mouth gag for temporomandibular joint injury is designed by the inventor, an upper object and a lower object can be expanded and opened along a small gap, the opened angle can be fixed, and the mouth gag can be used for mouth opening training after temporomandibular joint injury and can also be used in the field of industrial production after being modified.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome current defect, provide one kind can follow small gap expansion, two upper and lower objects open, but also can fix the angle of opening, the temporomandibular bone joint of simple operation is with gag. In order to solve the problem, the utility model adopts the following technical scheme:

the utility model provides a temporomandibular joint injury is with ware of opening one's mouth, includes preforming and lower preforming, upper and lower preforming head end is articulated through the connecting piece, the terminal inboard of upper and lower preforming is equipped with corresponding recess respectively, and the recess internal fixation has two gasbags that are used for strutting upper and lower preforming, and the both ends of recess are located respectively to two gasbags, two gasbags interconnect and link to each other with inflation equipment through the gas tube.

Furthermore, the tail ends of the upper and lower pressing sheets are of arc structures.

Furthermore, the inflation equipment is an electric inflation device, a manual inflator pump or a latex inflation ball.

The utility model relates to a temporomandibular joint injury uses gag, simple structure, convenient to use can make into the gag for temporomandibular joint injury of different sizes and configuration as required. The large-scale electric inflatable dilator can be used for repairing large-scale instruments after being reformed and can be manufactured into the large-scale electric inflatable dilator; the device is used for disassembling precise components and can be made into a latex inflatable ball type mouth gag and the like. When the inflation device stops inflating, the expanding angle can be fixed.

Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

The first embodiment is as follows:

as shown in fig. 1, the dilator comprises an upper pressing sheet 1 and a lower pressing sheet 2, the head ends of the upper pressing sheet 1 and the lower pressing sheet 2 are hinged through a connecting piece, the inner sides of the tail ends of the upper pressing sheet 1 and the lower pressing sheet 2 are respectively provided with a corresponding groove, two air bags 3 for opening the upper pressing sheet 1 and the lower pressing sheet 2 are fixed in the grooves, the two air bags 3 are respectively arranged at the two ends of the grooves, and the two air bags 3 are connected with each other and are connected with an inflation device through an inflation tube 4.

When the inflatable air bag is used, the upper pressing sheet 1 and the lower pressing sheet 2 can be covered with gaskets to prevent components from being scratched according to needs, and the air bag 3 is inflated by using an electric inflating device or a manual inflating pump to expand the upper pressing sheet 1 and the lower pressing sheet 2. When the inflation device stops inflating, the expanding angle can be fixed.

Example two:

as shown in figures 2-4, will temporomandibular joint damage use mouth gag be arranged in the medical field as the mouth gag uses because the head and neck malignant tumour patient can cause the damage of temporomandibular joint and masticatory muscle to form the difficulty of opening mouth after the radiation therapy, need carry out the mouth gag training. For convenient use, temporomandibular joint damage can be according to patient's gum model customization suitable size with the mouth gag to be equipped with the dental cast and use. In the embodiment, the head ends of the upper pressing sheet 2-1 and the lower pressing sheet 2-2 are hinged through a connecting piece, and the upper pressing sheet 2-1 and the lower pressing sheet 2-2 are arranged into an arc structure corresponding to the gum and are provided with a connecting structure (not shown in the figure) matched with the dental model for use. And (3) inflating the air bag 2-3 by using a latex inflatable ball to realize the opening and closing of the upper pressing sheet 2-1 and the lower pressing sheet 2-2, thereby completing the mouth opening training.

For convenience of use, two groups of air bags 2-3 are arranged in the embodiment, and the two groups of air bags 2-3 are respectively arranged at two ends of the groove 2-4 and are connected through an inflation tube. When in use, a patient or a nursing staff can hold the latex inflatable ball by hand to inflate the two groups of air bags 2-3, and the inflation amount and the opening amplitude of the upper pressing sheet 2-1 and the lower pressing sheet 2-2 can be adjusted according to the bearing limit of the patient. The patient or the nursing staff can judge the training effect of the patient by reading the scale value on the air bags 2-3.

Although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
