Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an oral opening and closing exercise device. Background Art

[0002] Radiotherapy is an important treatment method for patients with head and neck tumors, including nasopharyngeal carcinoma, oral cancer, hypopharyngeal cancer, etc. Due to radiotherapy causing local tissue edema, cell damage and fibrosis, patients are prone to have difficulty in opening their mouths, and early functional exercise can effectively prevent and improve the symptoms of difficulty in opening the mouth.

[0003] Currently, for nasopharyngeal cancer radiotherapy patients, mouth opening training mainly uses patients to hold a wooden plug or other round objects in their mouths and bite the wooden plug with their teeth to force the mouth to open. Since many patients have poor compliance and cannot cooperate with the treatment for a long time, and the size of the wooden plug is fixed and cannot be changed according to the different conditions of patients, it is impossible to carry out targeted treatment for patients, resulting in limited effect of oral opening and closing exercise.

[0004] Therefore, an oral opening and closing exercise device is needed to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide an oral opening and closing exercise device to solve the above problems.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme:

[0007] An oral opening and closing exercise device includes a fixed block, on which two symmetrically distributed fixed columns are fixedly connected. A spring is fixedly connected to the fixed block and sleeved on the fixed column. The fixed column is slidably connected to a sliding hole opened on a slider. A tension arm is fixedly connected to the slider, and an adjusting member for adjusting the moving distance of the slider is provided on the fixed block.

[0008] Preferably, the adjusting member includes a vertical rod fixedly connected to the fixed block. A through hole slidably connected to the vertical rod is opened on the slider, and the vertical rod is threadedly connected with a screw sleeve.

[0009] Preferably, an elastic rubber gasket protrudes from the part of the bottom of the screw sleeve in contact with the slider.

[0010] Preferably, a bent rod is fixedly connected to the fixed column, and a handle is installed on the bent rod.

[0011] Preferably, a clamping groove is opened on the tension arm, and the clamping groove is engaged with a clamping block fixedly connected to a silica gel block.

[0012] Preferably, one end of the spring is fixedly connected to the fixed block, and the other end is fixedly connected to the slider, and the elastic forces of the two springs push the two sliders away from each other.

[0013] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are as follows:

[0014] 1. In this application, under the action of the elastic forces of the two springs above and below the fixed block, the two sliders above and below the fixed block are pushed away from each other. When the upper and lower teeth of the patient bite on the tension arms, the two tension arms can be caused to approach each other, that is, the effect of opening and closing exercise is achieved. By rotating the screw sleeve, the moving distance of the slider in the vertical direction can be changed, that is, the size of the opening and closing exercise can be changed, which is relatively convenient.

[0015] 2. In this application, the silicone block connected to the tension arm contacts the patient's teeth. The silicone block has a certain elasticity. Therefore, when the patient's teeth bite on the silicone block, it is relatively soft, which can effectively improve the comfort of the opening and closing exercise. Moreover, even if the silicone block is deformed, it can be easily removed from the tension arm and a new silicone block can be replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0022] Please refer to Figures 1-3 , the present utility model provides a technical solution:

[0023] Oral opening and closing exercise device, including a fixed block 1, two symmetrically distributed fixed columns 2 fixedly connected to the fixed block 1, a spring 5 fixedly connected to the fixed block 1, and the spring 5 is sleeved on the fixed column 2. The fixed column 2 is slidably connected to a sliding hole 8 opened on the slider 6. A tension arm 7 is fixedly connected to the slider 6. One end of the spring 5 is fixedly connected to the fixed block 1, and the other end is fixedly connected to the slider 6. The elastic forces of the two springs 5 push the two sliders 6 away from each other. An adjusting member for adjusting the moving distance of the slider 6 is provided on the fixed block 1. There are sliders 6 on the upper and lower sides of the fixed block 1 respectively. The patient's teeth bite on the tension arms 7 on the sliders 6, causing the two tension arms 7 to approach each other, that is, achieving the exercise effect of oral opening and closing.

[0024] Specifically, as Figure 1 shown, the adjusting member includes a vertical rod 10 fixedly connected to the fixed block 1. A through hole 9 slidably connected to the vertical rod 10 is opened on the slider 6. The vertical rod 10 is threadedly connected with a screw sleeve 11. An elastic rubber gasket protrudes from the part of the bottom of the screw sleeve 11 in contact with the slider 6. When the screw sleeve 11 is rotated, the moving distance of the slider 6 on the fixed column 2 can be changed, that is, the moving distance between the two sliders 6 is changed, playing a role in changing the degree of oral opening and closing. Therefore, the patient can adjust the position of the screw sleeve 11 on the vertical rod 10 by himself to perform targeted oral opening and closing exercises.

[0025] Specifically, as Figure 3 shown, a bent rod 3 is fixedly connected to the fixed column 2, and a handle 4 is installed on the bent rod 3. The exercise device can be more conveniently controlled through the handle 4.

[0026] Specifically, as Figure 3 shown, a clamping groove 12 is opened on the tension arm 7, and the clamping groove 12 is engaged with a clamping block 14 fixedly connected to the silica gel block 13. Therefore, when the silica gel block 13 is deformed by being bitten by the patient's teeth during long-term use, a new silica gel block 13 can be easily replaced.

[0027] In summary, the patient in this embodiment can determine the distance between the two tension arms 7 according to the degree to which his own oral cavity can open. Subsequently, the screw sleeve 11 can be rotated, resulting in the two tension arms 7 moving closer to or away from each other. After the tension arms 7 move to a suitable position. The patient can bite on the silica gel blocks 13 on the two tension arms 7. During the opening and closing of the oral cavity, the two tension arms 7 move away from or close to each other, that is, performing oral opening and closing exercises.

[0028] The above description of the embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. Therefore, the present utility model will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
