Description

A manual mouth opener

technical field

The utility model relates to the technical field of medical auxiliary equipment, in particular to a manual mouth opener.

Background technique

Clinically, it is very difficult to implement voluntary oral expansion when performing mouth opening training for patients or assisting in the nursing examination of patients with impaired consciousness, and a mouth opener is needed for adjuvant treatment.

At present, when the patient is trained to open the mouth, a wedge-shaped hard rubber block or a stepped wooden block of moderate thickness is generally used as the mouth opener, and the thickness is gradually increased to gradually increase the opening degree, so that the patient is trained to open the mouth, but the existing The mouth opener is bulky and needs to be repeatedly inserted into the mouth, which is likely to cause mechanical damage to the teeth, and the size of the mouth opening cannot be controlled according to the individual needs of the patient. The patient's compliance with use is poor. Nausea, what's more, if the mouth opener is left in the mouth during the mouth opening exercise, it can cause the patient's airway to be blocked and suffocate to death.

During the oral observation and treatment of patients, once the mouth opening time is too long, the facial muscles of the patient are prone to fatigue, resulting in a different size of the mouth opening, and it is impossible to cooperate with the doctor for treatment. In addition, it is usually necessary to use The mouth opener opens the patient's oral cavity, is not easy to fix, and is not convenient for a single person to perform the operation of cleaning the oral cavity and observe the situation in the oral cavity. Therefore the utility model comes.

Based on the above problems, the technical solution provided by the utility model is:

A manual mouth opener, comprising an upper opening assembly and a lower opening assembly, the upper opening assembly and the lower opening assembly are hinged through a connecting shaft, the upper opening assembly includes an upper opening plate and a first handle, the lower opening assembly The assembly includes a lower opening plate and a second handle, an elastic member is provided between the first handle and the second handle, a fixing bolt is provided on the second handle, a through hole is provided on the first handle, and the The fixing bolts are limited by nuts.

Further, the upper opening plate and the first handle are connected at an obtuse angle, and the lower opening plate and the second handle are connected at a right angle.

Further, the upper opening plate and the lower opening plate match the physiological curvature of human alveolar.

Further, flexible teeth pads are provided on the upper opening plate and the lower opening plate.

Further, the elastic component is a leaf spring.

Compared with the prior art, the utility model has the advantages of:

1. Adopting the technical solution of the utility model, the upper opening plate and the lower opening plate are placed in the oral cavity to fit the teeth, and the patient applies force to the handle to separate the two opening plates by a certain distance, so that the oral cavity is opened. Reduced, the two opening plates are reset under the action of the elastic parts of the handle, so repeated, so as to perform recovery training on the patient's bilateral masticatory muscles or soft tissues around the temporomandibular joint;

2. With the technical solution of the utility model, the doctor can operate the mouth opener with one hand, and adjust the position of the first handle through the nut to fix the opening angle of the patient's mouth, which is convenient for observation and treatment of the patient's mouth;

3. Adopting the technical scheme of the utility model, the mouth opening trainer has a simple structure, is easy to use, does not directly contact the oral mucosa, and can prevent oral infection.

In order to more clearly illustrate the technical solutions of the embodiments of the utility model, the following will briefly introduce the accompanying drawings that need to be used in the description of the embodiments. The accompanying drawings in the following description are only some embodiments of the utility model. Those of ordinary skill in the art can also obtain other drawings based on these drawings without any creative effort.

Fig. 1 is the structural representation of the embodiment of a kind of manual mouth opener of the present utility model;

Fig. 2 is a top view of the upper opening plate in Fig. 1;

Among them: 1. Upper opening plate; 2. Lower opening plate; 3. First handle; 4. Second handle; 5. Elastic component; 6. Bolt; 7. Nut.

Detailed ways

The above solution will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are used to illustrate the utility model and not limit the scope of the utility model. The implementation conditions used in the examples can be further adjusted according to the conditions of specific manufacturers, and the implementation conditions not indicated are usually the conditions in routine experiments.

Referring to Fig. 1, it is a structural schematic diagram of an embodiment of the present invention, providing a manual oral mouth opener, including an upper opening assembly and a lower opening assembly, and the upper opening assembly and the lower opening assembly are hinged by a connecting shaft, wherein the upper opening assembly includes The interconnected upper opening plate 1 and the first handle 3, the lower opening assembly includes the interconnected lower opening plate 2 and the second handle 4, an elastic member 5 is arranged between the first handle 3 and the second handle 4, and the elastic member 5 is a spring leaf, and a limit assembly is provided between the first handle 3 and the second handle 4, and the limit assembly makes the first handle 3 and the second handle 4 in a compressed state. In this example, on the second handle 4 A bolt 6 is provided, and a through hole is provided on the first handle 3 to facilitate the passage of the bolt 6 , and a nut 7 is provided to limit the position of the first handle 3 .

In order to improve the use comfort of the mouth opener of the utility model, the upper opening plate 1 and the first handle 3 are connected at an obtuse angle, and the lower opening plate 2 and the second handle 4 are connected at a right angle.

In order to further optimize the implementation effect of the utility model and increase the force-bearing area of the human oral cavity when opening the mouth, referring to Fig. 2, the upper opening plate 1 and the lower opening plate 2 are set to match the physiological radian of the human alveolar.

In order to prevent the upper opening plate 1 and the lower opening plate 2 from mechanically damaging the teeth, flexible tooth pads are respectively provided on the upper opening plate 1 and the lower opening plate 2 .

The usage method of the utility model is as follows: when the patient is trained to open the mouth, adjust the nut according to the patient's condition to adjust the maximum opening angle of the mouth opener, open a certain gap in the patient's oral cavity by hand, and place the upper opening plate and the lower opening plate Embedded in the oral cavity, the patient holds the handle with one hand and exerts force on the first handle, so that the two opening plates are opened, and the oral cavity is opened. By manually applying force, the greater the force, the larger the oral opening will be. When gradually reducing the grip When the force is applied, the first handle will automatically rebound under the action of the elastic component, and the two opening plates will be closed. Repeatedly, the mouth opening training can be carried out; when the patient needs to be observed or treated, the patient's mouth can be opened by hand Insert the upper opening plate and the lower opening plate into the oral cavity with a certain gap. The doctor holds the handle with one hand and applies force to the first handle to make the two opening plates open and open the oral cavity. When the oral cavity reaches the optimal opening angle , adjust the position of the nut to fix the position of the first handle, thereby facilitating the observation and treatment of the oral cavity of the patient.

The above examples are only to illustrate the technical concept and characteristics of the present utility model, and its purpose is to allow those familiar with this technology to understand the content of the present utility model and implement it accordingly, and cannot limit the protection scope of the present utility model with this.
