BRIEF DESCRIPTION OF THE DRAWINGS
[0016] The present invention will be further described below in conjunction with the accompanying drawings:
[0017] Figure 1 is a schematic diagram of the overall structure of a medical mouthpiece in an embodiment of the present invention;
[0018] Figure 2 Schematic diagram of the structure of the mouthpiece body in an embodiment of the present invention. DETAILED DESCRIPTION
[0019] Reference Figure 1 , Figure 2 The present invention is a medical mouthpiece, comprising a mouthpiece body 1, a side of the mouthpiece body 1 that penetrates into the oral cavity is provided with an expandable and contractible capsule 2, and a pipe 3 connected to the capsule 2 is also provided. A valve 4 is provided at one end of the pipe 3, and one end of the valve 4 is connected to a filling device 8.
[0020] Specifically, when in use, the mouthpiece body 1 is placed in the patient's oral cavity with the side of the capsule 2 facing inward. After the mouthpiece body 1 is completely in the oral cavity, the capsule 2 can be filled with water using the filling device 8 according to the patient's tolerance, so that the capsule 2 expands to fit tightly against the patient's palate. Since the mouthpiece body has completely pressed the tongue underneath, the mouthpiece body 1 can effectively fix the patient's tongue, reduce movement caused by breathing and swallowing, and improve the accuracy of irradiation during radiotherapy. The capsule 2 after water injection can completely fit against the palate, thereby increasing the surface dose of the hard palate. When use is over, the liquid inside the capsule 2 can still be sucked out by the filling device 8 to reduce the volume of the capsule 2 and easily remove the medical mouthpiece.
[0021] As a special case, during the treatment of some patients, it is necessary to inject liquid medicine into the capsule 2 to achieve a certain fumigation effect, which can improve the absorption capacity of the irradiated target area to the radiation and improve the therapeutic effect of the radiation.
[0022] As a preferred embodiment of the present invention, the cross-sectional area of the mouthpiece body 1 gradually changes along the center line, and the area of the end surface of the mouthpiece body 1 that penetrates into the oral cavity is smaller than the area of the end surface of the mouthpiece body 1 that faces the outside of the body. Specifically, the area of each cross section of the mouthpiece body 1 gradually decreases from the end surface facing the outside of the body to the end surface that penetrates into the oral cavity, making it easier for the mouthpiece body 1 to be placed in the oral cavity.
[0023] As a preferred embodiment of the present invention, the pipeline 3 includes an internal channel arranged inside the mouthpiece body 1, one end of the internal channel is connected to the capsule 2, and the other end of the internal channel is connected to the external pipeline 3 located outside the mouthpiece body 1, and one end of the external pipeline 3 is connected to the valve 4. The internal channel is arranged on the mouthpiece body 1, which can effectively reduce the volume of the pipeline 3, making the structure of the entire medical mouthpiece more compact and more convenient to operate.
[0024] As a preferred embodiment of the present invention, a vent hole 5 for breathing is provided in the mouthpiece body 1, and the vent hole 5 runs through the mouthpiece body 1, and the width of the vent hole 5 is 5 mm. When the mouthpiece body 1 is placed in the oral cavity, the breathing passage will be blocked, so the vent hole 5 is provided to meet the breathing needs of the patient.
[0025] As a preferred embodiment of the present invention, the cross-sectional shape of the mouthpiece body 1 is an oblate circle, and the oblate circle cross-sectional shape conforms to ergonomics, so that when the mouthpiece body 1 is placed in the oral cavity, it can fully contact the oral cavity.
[0026] As a preferred embodiment of the present invention, a scale 6 for observing the mouth entry depth is provided on the side of the mouthpiece body 1. Medical staff can obtain the mouth entry depth of the mouthpiece by observing the scale 6, thereby controlling the degree of mouth opening of the patient, improving the repeatability of each irradiation of the target area and normal tissue, thereby ensuring the dose accuracy of the target area and normal tissue.
[0027] As a preferred embodiment of the present invention, a notch 7 is provided on the side of the mouthpiece body 1 that penetrates into the oral cavity to prevent over-stimulation of the hard palate from causing nausea.
[0028] As a preferred embodiment of the present invention, the notch 7 is U-shaped. The U-shaped notch 7 can prevent the mouthpiece body 1 from irritating the soft palate in the patient's oral cavity and causing adverse effects such as nausea.
[0029] As a preferred embodiment of the present invention, the mouthpiece body 1 is made of medical silicone material.
[0030] As a preferred embodiment of the present invention, the capsule 2 can be expanded by injecting liquid into it. After the capsule 2 is expanded, it becomes a rectangle with two corners cut off, and the side of the rectangle without two corners cut off faces the end of the mouthpiece body 1 that goes deep into the oral cavity. Since the shape of the upper palate in the oral cavity gradually widens from the mouth to the throat, in order to ensure that the capsule 2 can fully contact the upper palate of the oral cavity after expansion, so as to better increase the irradiation dose of the upper palate, the shape of the capsule 2 after expansion is designed to be a rectangle with two corners cut off, and the end of the rectangle without corners cut off faces the end of the mouthpiece body 1 that goes deep into the oral cavity. This design makes the shape of the capsule 2 after expansion more consistent with the shape of the oral cavity, conforms to ergonomics, and improves the comfort of use and the irradiation dose of the upper palate.
[0031] This medical mouthpiece is provided with a capsule 2 with a variable volume. The volume of the capsule 2 is changed by water injection, so that the capsule 2 can fit the patient's oral palate, thereby ensuring the accuracy of radiotherapy, improving the surface dose of the palate, and being able to meet the needs of patients in different situations. It has strong adaptability and a wide range of applications. The scale 6 can accurately control the depth of the mouthpiece body 1 into the mouth, thereby improving the repeatability of each exposure of the target area and normal tissue, ensuring the accuracy of the dose, and enhancing the effect of radiotherapy. The entire medical mouthpiece has a simple structure and is easy to operate, and has a high promotion value.
[0032] Of course, the invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
