Technical Field
[0001] The utility model belongs to the field of radiotherapy mouthpieces, in particular to a medical tumor radiotherapy mouthpiece. Background Art
[0002] Radiotherapy or comprehensive treatment mainly based on radiotherapy is the basic principle for treating head and neck tumors in the current medical field. Tumors require radiotherapy during their treatment. However, during radiotherapy, while killing mutant cells, the radiation will damage normal cells, causing damage to parotid gland function, oral mucosa and taste, etc. The incidence of radiation damage to the oral mucosa and tongue is extremely high. Therefore, it is necessary to use a radiotherapy mouthpiece to fix normal tissues as far away from the target area as possible to protect the inner wall of the oral cavity. In current clinical applications in hospitals, relatively simple radiotherapy mouthpieces such as medicine bottles, corks, tongue depressors, and syringe barrels are mostly used before radiotherapy to push the tongue and oral mucosa to the radiotherapy position. However, this relatively simple radiotherapy mouthpiece has a small area of contact with the inner wall of the oral cavity, and the fixing effect is general and it is easy to cause pressure injuries to the inner wall of the oral cavity. The existing radiotherapy mouthpiece cannot be adjusted, resulting in some patients with smaller mouths being unable to use it normally, and the patient's experience is poor. Utility Model Content
[0003] The utility model aims to provide a medical tumor radiotherapy mouthpiece, which has good fixing effect, does not cause damage to the inner wall of the oral cavity, and can adapt to different patients.
[0004] The medical tumor radiotherapy mouthpiece comprises two support platforms symmetrically arranged with an upper and lower interval, a plurality of telescopic rods are fixed between the two support platforms, a mounting groove is provided on the side of the two support platforms away from each other, braces are detachably installed in the mounting groove, and positioning grooves are provided on the side walls of the two braces facing the upper and lower front teeth respectively, a support plate is vertically fixed on one of the support platforms, a mounting opening is provided on the side wall of the support plate facing the inside of the oral cavity, a pressure plate is horizontally fixed on the mounting opening, an air bag is mounted on the pressure plate, the open end of the air bag is detachably fixed on the mounting opening, an trachea for connecting to an external air injection device and transmitting air to the air bag is connected on the side of the support plate away from the oral cavity, a through hole connecting the mounting opening and the trachea is provided on the support plate, and a blocking component for preventing air leakage is provided on the trachea.
[0005] Furthermore, the blocking assembly includes two splints, which are located on both sides of the trachea, one ends of the two splints are hinged to each other, and a buckle is provided between the other ends of the two splints for locking the swinging ends of the two splints after swinging.
[0006] Furthermore, the positioning groove is opened in an arc shape, and the cross section of the positioning groove is a "V"-shaped structure.
[0007] Furthermore, the airbag has a disc-shaped structure.
[0008] Furthermore, anti-slip grooves are provided on the upper and lower side walls of the airbag.
[0009] Furthermore, the braces are made of elastic material.
[0010] Furthermore, positioning lines are vertically provided on the side walls of the two support platforms facing outside the oral cavity.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] First, insert the airbag and pressure plate into the patient's mouth, and use the pressure plate to press the patient's tongue downward, so as to preliminarily position the patient's tongue and avoid the tongue from moving and deviating before the airbag is inflated; by extending the overall length of the telescopic rod, the distance between the two support platforms is adjusted to support the patient's upper and lower jaws and open the patient's mouth. Only two support platforms are needed to support the patient's upper and lower incisors, so that the volume is small and can adapt to patients with different mouth sizes; then the air injection device injects air into the airbag through the trachea, and the airbag inflates and fits on the upper jaw and tongue, thereby avoiding pressure injuries to the inner wall of the oral cavity. The inflated airbag lifts the patient's upper jaw and squeezes and fixes the patient's tongue, so that the normal tissue in the oral cavity is fixed as far away from the target area as possible, and the inner wall of the oral cavity is protected. Finally, the trachea is sealed through the blocking component to prevent air leakage in the airbag, which can be reused in subsequent radiotherapy. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
[0019] Example 1
[0020] The medical tumor radiotherapy mouthpiece described in this embodiment is as follows: Figure 1 , Figure 2 and Figure 4 As shown, it includes two support platforms 4 symmetrically arranged at an upper and lower interval, the support platforms 4 are arc-shaped, and are used to align with the upper and lower incisors of the human body respectively. Only two support platforms 4 are needed to support the upper and lower incisors of the patient, so the volume is small and can adapt to patients with different mouth sizes. The arc-shaped support platform 4 can reduce the volume while reducing the material, reduce the collision with the patient's lips, avoid damage to the lips, and reduce the discomfort of the patient's mouth during use;
[0021] A plurality of telescopic rods 7 (telescopic parts) are fixed between the two support platforms 4. In the present embodiment, the telescopic rods 7 are divided into two groups, and the two groups of telescopic rods 7 are symmetrically arranged at intervals. The telescopic rods 7 include a first pipe and a second pipe, and the second pipe is inserted into the first pipe. A fixing assembly is arranged on the first pipe. One end of the first pipe and the second pipe is respectively fixed on the two support platforms 4. The second pipe is moved in the first pipe to change the length of the combination of the two pipes, thereby adjusting the spacing between the two support platforms 4, and then fixed by the fixing assembly. The above-mentioned does not necessarily have to be a pipe, and can be other shapes, such as a rectangle; of course, the telescopic parts can also adopt a bidirectional threaded rod and two threaded sleeves, and the two threaded sleeves are respectively mounted on the two threaded sections of the bidirectional threaded rod, and one end of the two threaded sleeves is respectively fixed on the two support platforms 4. A handle is mounted on the middle section of the bidirectional threaded rod, so that the handle drives the bidirectional threaded rod to rotate by rotating the handle, so that the two threaded sleeves move relatively along the bidirectional threaded rod, thereby adjusting the spacing between the two support platforms 4;
[0022] A mounting groove is provided on one side of the two support platforms 4 which are away from each other, and a dental cap 5 is detachably mounted in the mounting groove. The dental cap 5 is made of materials such as silicone, natural rubber latex, nitrile rubber latex, chloroprene rubber latex, styrene-butadiene rubber or thermoplastic elastomer solution or emulsion, styrene-butadiene rubber emulsion, etc. The dental cap 5 is arc-shaped, and the curvature is the same as that of the support platform 4. The dental cap 5 is fixed to the groove wall of the groove by glue, and of course double-sided tape can also be used, which is convenient for disassembly and assembly, so that the mouthpiece can be used repeatedly.
[0023] Positioning lines 12 are vertically provided on the side walls of the two support platforms 4 facing the outside of the oral cavity. When the mouthpiece is used for the first time, the positioning lines 12 on the two support platforms 4 can be respectively aligned with the incisor gaps between the upper and lower incisors of the patient to position the mouthpiece. When it is reused subsequently, the positioning lines 12 on the two support platforms 4 can be respectively aligned with the incisor gaps between the upper and lower incisors of the patient, so that the mouthpiece can be located at the same position as the first time it is used during the subsequent use, so that the subsequent installation position and the first installation position can be more accurate, thereby avoiding changes in the position of normal oral tissue during subsequent radiotherapy;
[0024] The two mouthpieces 5 are provided with positioning grooves 6 on the side walls facing the upper and lower front teeth, respectively. The positioning grooves 6 are arc-shaped, and the cross section of the positioning grooves 6 is a "V"-shaped structure. The arc of the positioning grooves 6 is roughly the same as the arc of the upper and lower teeth of the human body. The positioning grooves 6 with a "V"-shaped cross section can make the front teeth fit fully with the groove wall of the positioning grooves 6, so that the mouthpiece can be better fixed in the patient's oral cavity;
[0025] A support plate 11 is vertically fixed on one of the support platforms 4. In the embodiment of this city, the support plate 11 is fixed on the top of the support platform 4 corresponding to the lower teeth of the human body;
[0026] A mounting opening 3 is provided on the side wall of the support plate 11 facing the inside of the oral cavity, and a pressing plate 2 is horizontally fixed on the mounting opening 3. The cross section of the mounting opening 3 is an elliptical structure, and of course other shapes such as square, circle, etc. can also be used; the pressing plate 2 is fixed to the end of the mounting opening 3 facing the inside of the oral cavity; when in use, the patient's tongue can be preliminarily positioned by the pressing plate 2 to prevent the tongue from moving and deviating before the airbag 1 is inflated;
[0027] The pressure plate 2 is provided with an airbag 1, which is in a disc-shaped structure. The upper and lower side walls of the airbag 1 are provided with anti-skid patterns 13. The disc-shaped airbag 1 can increase the fit between the patient's tongue and palate, and prevent the airbag 1 from rotating and deviating after expansion. After the airbag 1 is fitted with the patient's tongue and palate, the anti-skid patterns 13 can increase the friction between the surface of the airbag 1 and the patient's tongue and palate, thereby preventing the airbag 1 from moving in the patient's mouth.
[0028] The open end of the airbag 1 is detachably fixed on the mounting opening 3. In this embodiment, the open end of the airbag 1 is mounted on the mounting opening 3, and the open end of the airbag 1 and the mounting opening 3 are bonded by glue. When replacing the airbag 1, it is only necessary to clean the glue and reinstall the airbag 1. Of course, it can also be fixed by a rubber band. After the open end of the airbag 1 is mounted on the mounting opening 3, the open end of the airbag 1 is tied to the mounting opening 3 by a rubber band. The airbag 1 is made of soft materials such as medical rubber, silicone, latex, etc.
[0029] A trachea 9 for connecting to an external gas injection device to transmit air to the airbag 1 is connected on the side of the support plate 11 away from the oral cavity. A through hole connecting the mounting port 3 and the trachea 9 is provided on the support plate 11. In this embodiment, a connecting port 10 is fixed on the side of the support plate 11 away from the oral cavity. One end of the trachea 9 is sleeved on the connecting port 10. The through hole is connected to the connecting port 10 and the mounting port 3, so that the external gas injection device is connected to the trachea 9, thereby inflating the airbag 1 through the trachea 9, allowing the airbag 1 to expand and lift the patient's upper jaw and squeeze and fix the patient's tongue, so that the normal tissue in the oral cavity is fixed at a position as far away from the target area as possible, and the inner wall of the oral cavity is protected; the gas injection device can be an air pump or a syringe, etc.;
[0030] To further explain, Figure 1 , Figure 3 and Figure 4 As shown, the present embodiment preferably includes two splints 8, the two splints 8 are located on both sides of the trachea 9, one ends of the two splints 8 are hinged to each other, and one end of the two splints 8 is hinged by a pivot. During installation, a through hole for independent installation of the pivot is first opened on one of the splints 8, and the pivot is fixed on the other splint 8, so that one end of the two splints 8 is hinged, so that the two splints 8 can swing and clamp the trachea 9; a buckle (locking piece) for locking the swinging ends of the two splints 8 after swinging is provided between the other ends of the two splints 8, and the buckle includes a buckling portion provided on the swinging end of one of the splints 8, and the buckling portion is hook-shaped. When the swinging ends of the two splints 8 are closed, the swinging end of the other splint 8 will be engaged in the buckling portion, thereby locking the swinging ends of the two splints 8 after swinging and closing The two splints 8 are locked so that the trachea 9 is clamped and sealed. Of course, the locking member can also be a screw. A through hole for the screw to pass through is opened on the swinging end of one of the splints 8, and a threaded hole that threadedly cooperates with the screw is opened on the swinging end of the other splint 8. When the two splints 8 are swung closed, the screws are turned to lock the swinging ends of the two splints 8 by the screws. This section of the scheme as a whole constitutes a blocking component for preventing air leakage. Of course, the blocking component can also be a plug. The plug is made of materials such as silicone, natural rubber latex, nitrile rubber latex, chloroprene rubber latex, styrene-butadiene rubber or thermoplastic elastomer solution or emulsion, styrene-butadiene rubber emulsion, etc. When the airbag 1 is fully inflated, the plug is inserted into one end of the trachea 9, and one end of the trachea 9 is sealed by the elastic force of the plug itself.
[0031] In actual use, the airbag 1 and the pressure plate 2 are first inserted into the patient's oral cavity, and the patient's tongue is pressed downward by the pressure plate 2 to preliminarily position the patient's tongue. The positioning lines 12 on the two support platforms 4 are aligned with the gap between the patient's upper and lower front teeth to position the mouthpiece, so that when it is reused later, the mouthpiece can be quickly installed in the position when it was used for the first time to avoid changes in the position of normal oral tissue during subsequent radiotherapy. After the support platforms 4 are aligned, the overall length of the telescopic rod 7 is adjusted so that the two support platforms 4 are in opposite directions. Move the trachea 9 to allow the patient's upper and lower incisors to be respectively engaged in the positioning grooves 6 on the two braces 5, thereby supporting the patient's upper jaw and lower jaw and opening the patient's mouth. Then, connect one end of the trachea 9 to an external gas injection device, which injects air into the airbag 1 through the trachea 9 to expand the airbag 1 and lift the patient's upper jaw and squeeze and fix the patient's tongue, so that the normal tissue in the oral cavity is fixed at a position as far away from the target area as possible, and the inner wall of the oral cavity is protected. Finally, the two splints 8 are swung to clamp and seal the trachea 9 to prevent air leakage in the airbag 1.
